The two shorter sides of an right triangle measure 15 inches and 3 feet. What is the length of the longest side?

Answer:

Step-by-step explanation:

Carlos can expect the value of the computer to be $580 in 3 years after purchase.

To find the exponential equation in the form y=a(b)ˣ that models the value of the computer, we need to determine the initial value and the rate of decay.

The initial value of the computer is $1,350, and its value after one year is $810.

We can use this information to find the rate of decay as follows:

810 = 1350 × b¹

b = 0.6

So the exponential equation is:

y = 1350(0.6)ˣ

To find the value of the computer 3 years after purchase, we can substitute x = 3 into the equation:

y = 1350(0.6)³= 583.2

Hence, Carlos can expect the value of the computer to be $580 in 3 years after purchase.

The value of x is 15 when y =8

If x varies indirectly as y, then we can write:

x = k/y

where k is the constant of variation. To find the value of k, we can use the given information that x = 5 when y = 24:

5 = k/24

Multiplying both sides by 24, we get:

k = 120

Now we can use this value of k to find x when y = 8:

x = 120/8 = 15

Therefore, the answer is A. 15.

A ratio that depicts the association between the independent variable (x) and the dependent variable is known as a constant of variation (k) (y). In the event that both of those variables have known values, it can be calculated by dividing y by x.

The height of the triangle is approximately 7.31 units.

What is  Pythagorean theorem ?

The Pythagorean theorem is a fundamental theorem in geometry that relates to the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

In mathematical notation, the Pythagorean theorem can be written as:

a^2 + b^2 = c^2

where a and b are the lengths of the legs (the sides adjacent to the right angle) and c is the length of the hypotenuse.

According to the question:

Since triangle ABC is a right triangle with angle B = 90 degrees, we can use the Pythagorean theorem to find the length of side BC:

[tex]BC^2 = AC^2 - AB^2[/tex]

[tex]BC^2 = 30^2 - h^2[/tex]

[tex]BC = \sqrt{30^2 - h^2}[/tex]

Now, let's consider triangle ABD. We know that AD = 25 and DC = 11, so BD = BC - DC:

BD = BC - DC

[tex]BD = \sqrt{30^2 - h^2} - 11[/tex]

Since the line passing through vertex A is perpendicular to BC, we know that triangles ABD and ABC are similar. Therefore, we can use the ratio of corresponding sides to find the value of h:

h/AB = AB/AC

h/AB = AB/30

[tex]AB^2 = h*30[/tex]

[tex]AB =\ sqrt{h*30}[/tex]

Now, using the fact that AD + DC = BC, we can write:

AD + DC = BD + AB

[tex]25 + 11 = \sqrt{30^2 - h^2} - 11 +\sqrt{h*30}[/tex]

[tex]36 = \sqrt{30^2 - h^2} + \sqrt{h*30}[/tex]

Squaring both sides, we get:

[tex]1296 = 30^2 - h^2 + 2\sqrt{h*30}\sqrt{30^2 - h^2} + h*30[/tex]

[tex]1296 = 900 - h^2 + 2\sqrt{30h - h^3} + 30*h[/tex]

[tex]396 = 32\sqrt{30*h - h^3}[/tex]

Squaring again, we get:

[tex]156816 = 960h^2 - 96h^4[/tex]

[tex]h^4 - 10h^2 + 1639/12 = 0[/tex]

Using the quadratic formula, we get:

[tex]h^2 = (10 \± \sqrt{10^2 - 4(1)(1639/12))}/2[/tex]

[tex]h^2 = (10 \± \sqrt{1561})/2[/tex]

Since h must be positive, we take the positive square root:

[tex]h = \sqrt{(10 + sqrt(1561)}/2) \approx 7.31[/tex]

Therefore, the height of the triangle is approximately 7.31 units.

Based on the information provided, the relationship between velocity and time taken is V = 4 + 0.5t.

We can start by using the formula for velocity with constant acceleration:

V = Vo + at

where V is the final velocity, Vo is the initial velocity, a is the constant acceleration, and t is the time taken.

We know that the velocity is partly constant and partly varies with time, so we can write:

V = Vc + Vv

where Vc is the constant part of the velocity and Vv is the part that varies with time.

Using the given information, we can set up a system of equations:

9 = Vc + Vv (when t = 8s)

11 = Vc + Vv (when t = 12s)

Subtracting the first equation from the second, we get:

11 - 9 = (Vc + Vv) - (Vc + Vv)

2 = Vv (when t = 12s) - Vv (when t = 8s)

2 = Vv (12) - Vv (8)

2 = 4Vv

Vv = 0.5 m/s

Now we can use either of the two original equations to find Vc:

9 = Vc + 0.5(8)

Vc = 4 m/s

Therefore, the relationship between the velocity and the time taken is:

V = 4 + 0.5t

According to the question, it takes Mina 80 minutes to commute to work.

Two equations are considered to be comparable when their roots and solutions line up. To create an equivalent equation, the identical quantity, symbol, or expression must always be added to or removed from both of the equation's two sides. We can also create a similar equation simply multiplying or dividing either sides of the an equation by a nonnegative value.

Let's denote the time it takes Mina to commute to work by "m" (in minutes).

The issue states that Katie's train trip requires 10 minutes or more half as much time as Mina's drive. Instead, we might write:

Katie's commute time = (1/2) * Mina's commute time + 10

We also know that it takes Katie 30 minutes to get to work, so we can write:

Katie's commute time + 30 minutes = total time to get to work

The result of putting the very first equation into to the second equation is:

[(1/2) * Mina's commute time + 10] + 30 minutes = total time to get to work

Simplifying the equation, we get:

(1/2) * Mina's commute time + 40 minutes = total time to get to work

Now we can set this equation equal to "m" to solve for Mina's commute time:

(1/2) * m + 40 = m

Subtracting (1/2) * m from both sides, we get:

40 = (1/2) * m

Multiplying both sides by 2, we get:

m = 80

Therefore, it takes Mina 80 minutes to commute to work.

Given sin∠X = cos∠Y and m∠X = 72°, we can find the measure of angle Y to be 18° since angles X and Y are complementary.

The problem states that sin∠X = cos∠Y and m∠X = 72°, and we are asked to find the measure of angle Y.

The first thing to notice is that sin∠X = cos∠Y means that the sine of angle X is equal to the cosine of angle Y. By the definition of sine and cosine, we know that:

sin∠X = opposite/hypotenuse

cos∠Y = adjacent/hypotenuse

where "opposite" and "adjacent" are the lengths of the sides of a right triangle that correspond to angles X and Y, respectively, and "hypotenuse" is the length of the hypotenuse of the triangle.

Since sin∠X = cos∠Y, we can set the two expressions equal to each other:

sin∠X = cos∠Y

opposite/hypotenuse = adjacent/hypotenuse

opposite = adjacent

This tells us that the lengths of the opposite and adjacent sides of the right triangle are equal. Since these sides are opposite and adjacent to angles X and Y, respectively, this means that angles X and Y are complementary angles (i.e., the sum of their measures is 90°).

We know that angle X has a measure of 72°, so we can use the fact that angles X and Y are complementary to find the measure of angle Y:

m∠Y = 90° - m∠X

m∠Y = 90° - 72°

m∠Y = 18°

Therefore, the measure of angle Y is 18°.

Two airplanes are flying in the air at the same height. airplane a is flying east at 453 mi/h and airplane b is flying north at 508 mi/h. if they are both heading to the same airport, located 7 miles east of airplane a and 8 miles north of airplane b, at the rate at which the distance between the two airplanes is changing is approximately 473 mi/h.

What is the distance between the airplanes?

We may use the Pythagorean theorem to find the distance between the two airplanes. Let’s use A to represent the position of Airplane A and B to represent the position of Airplane B.

Let d be the distance between the airplanes. Then, using the Pythagorean Theorem, we have:

d² = (8 miles)² + (7 miles)² d² = 64 + 49d² = 113d = sqrt(113) miles

Since Airplane A is flying straight to the airport, its rate of approach to the airport is its speed, 453 mi/h.

Since Airplane B is flying straight to the airport, its rate of approach to the airport is its speed, 508 mi/h.

Let d be the distance between the airplanes at some point in time t. We need to find the rate at which the distance is changing, or the derivative of d with respect to t. We may use the Pythagorean theorem to find the distance between the two airplanes.

Let A represent the position of Airplane A and B represent the position of Airplane B.Let d be the distance between the airplanes. Then, using the Pythagorean Theorem, we have:

d² = (8 miles)² + (7 miles)² d² = 64 + 49d² = 113d = sqrt(113) miles

At some time t, let A(t) represent the position of Airplane A, and let B(t) represent the position of Airplane B. We have that:

A(t) = 453t B(t) = 508t

Therefore, the distance between the airplanes is given by:

d(t)² = (453t)² + (508t)²d(t)² = 205,609t² + 258,064t²d(t)² = 463,673t²

We take the derivative of both sides with respect to t, noting that d²/dt² = 2dd/dt:

2d(t)d'(t) = 927,346t

Then, dividing both sides by 2d(t), we have:

[tex]d'(t) = 927,346t/(2d(t))d'(t) = 927,346t/(2sqrt(113)) miles/h[/tex]

Using t = 1 hour (since we are asked for the rate at which the distance between the airplanes is changing), we have:

[tex]d'(1) = 927,346/(2sqrt(113))d'(1) ≈ 473 miles/h[/tex]

The area of the triangle with sides of lengths 10, 9, and 6 is approximately 37 square units.

What is the Pythagorean theorem?

In a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

To find the area of a triangle, we can use the formula:

Area = 1/2 * base * height

In this case, we need to identify the base and height of the triangle.

The longest side of the triangle is 10, which is opposite to the largest angle, so we can take that as the base. Let's call it b.

To find the height, we need to draw an altitude from the vertex opposite the base. Let's call the height h.

Now, we can use the Pythagorean theorem to find the height:

h^2 = 10^2 - (9^2 + 6^2)/2^2

h^2 = 100 - 45.25

h^2 = 54.75

h = sqrt(54.75)

h = 7.4 (rounded to one decimal place)

Now that we have the base and height, we can use the formula to find the area:

Area = 1/2 * base * height

Area = 1/2 * 10 * 7.4

Area = 37 square units (rounded to the nearest whole number)

Therefore, the area of the triangle with sides of length 10, 9, and 6 is approximately 37 square units.

Now, as we are given mean and standard deviation, we can standardize the normal distribution and then use the Z table or calculator to find the probability.
The formula for standardizing the normally distributed curve:
Z = (X - μ) / σ
where
Z = Standardized score
X = Score value
μ = Mean
σ = Standard deviation
Here, we have to find the probability of a randomly selected box of cold medicine will cost more than $13.
So, the formula becomes:

After computing the composition of f(g(x)) and g(f(x)), it is clear that f(x) and g(x) are not inverse functions of each other.

To determine whether f(x) and g(x) are inverse functions of each other, we need to check whether the composition of the two functions f(g(x)) and g(f(x)) result in the identity function, which is equal to x.

First, let's find f(g(x)):

f(g(x)) = f(5x - 5/4) (substituting g(x) into f(x))

f(g(x)) = 4/5(5x - 5/4) + 1 (substituting the expression for f(x))

f(g(x)) = 4x - 1 + 1

f(g(x)) = 4x

Now let's find g(f(x)):

g(f(x)) = g(4/5x + 1) (substituting f(x) into g(x))

g(f(x)) = 5(4/5x + 1) - 5/4 (substituting the expression for g(x))

g(f(x)) = 4x + 5 - 5/4

g(f(x)) = 4x + 20/4 - 5/4

g(f(x)) = 4x + 15/4

Since f(g(x)) = 4x and g(f(x)) = 4x + 15/4, we can see that the two compositions are not equal to x, which means that f(x) and g(x) are not inverse functions of each other.

Therefore, we can conclude that f(x) and g(x) are not inverse functions of each other.

Answer:

Step-by-step explanation:

For the given function f(x)=  [tex]-8(2)^{3x}[/tex] + 3 which contains variable x , whose value on substituting as zero is found to be (calculated without using calculator)

What is variable?

Variable is a term used in algebra or algebraic expressions and equations to represent the unknown values or whose value is not fixed. variables and constants are combined to form algebraic expressions or equations. The difference between expression and an equation is that expressions do not contain 'equal to' sign and equations shows balance between left hand side and the right side using 'equal to' sign.

Here the function is f(x)=  [tex]-8(2)^{3x}[/tex] + 3

To find the value of given function at x= 0 , we need to substititute zero in place of x.

f(x) at x=0 will be [tex]-8(2)^{3(0)}[/tex] + 3

                        = [tex]-8(2)^{0}[/tex] + 3

                        = [tex]-8(1)[/tex] + 3  { we know that [tex]m^{0} = 1[/tex] }

                        = - 8 + 3

                        = -5

∴The value of function at x=0 is found to be -5

there are 407,230 possible coupon codes that can be generated using the given format.

To find the number of possible coupon codes, we need to count the total number of ways to choose three letters from 23, one digit from 10, and one letter from 23 (since we can repeat letters). Combinations

The number of ways to choose three letters from 23 is:  

23[tex]C_{3}[/tex] = (232221)/(321) = 1771    

The number of ways to choose one digit from 10 is simply 10.

The number of ways to choose one letter from 23 (allowing repetition) is 23.

Therefore, the total number of possible coupon codes is:

1771 * 10 * 23 = 407,230

So there are 407,230 possible coupon codes that can be generated using the given format.
