Answer:

y = (-3)2^x

Step-by-step explanation:

We can substitute the two points in the equation y = abˣ and we get two equations. By solving the two equations, we can find the values of a and b.

Substitute (0, -3)  in the equation y = abˣ            

-3 = a * b⁰            

-3 = a * 1              

[tex]\boxed{\bf a = -3}[/tex]

Substitute (4, -48) in the equation y =abˣ

-48 = (-3) * b⁴

[tex]\dfrac{-48}{-3}=b^4\\\\ b^4 = 16\\\\b^4 = 2^4\\\\ \boxed{\bf b = 2}[/tex]

Table 4

Step-by-step explanation:

The first table is a linear function, with the points of (-240), (-72), (0), (2), and (6).

The second table is also a linear function, with the points of (-768), (-16), (0), (48), and (384)

The third table is a linear function, with the points of (-48), (-6), (0), (6), and (48)

The fourth table is the only one that is a linear function because the first four points are (0) and the last one is (-12)

The appropriate choice is for all actual x values of x 1.5, the function is declining.

A linear polynomial is a polynomial of degree one, which means it is a polynomial that has only one variable raised to the power of one and no other variables or exponents.

A function f(x), which is made up of two linear polynomials, is given as follows:

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

We now know that when we multiply the two linear polynomials, a quadratic polynomial results.

As a result, the function f(x) will be shown as:

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

f(x)=x²+x-4x-4

f(x)=x²-3x-4

In order to determine which claims about the function are accurate, we shall plot the function's graph.

1) The function increases for all real x values greater than zero.

Since we get from the graph that function f(x) is decreasing for x<0.

This statement is false.

2)The function is increasing for all real values of x where x < –1 and where x > 4.

This option is incorrect as the function is decreasing for x<-1

whereas it is increasing for x>4.

3)Where -1 <x<4, the function decrements for all real values of x.

This is the incorrect choice.

Because of the function's dual trend of growing and dropping in the interval (-1,4).

4)For all actual x values of x< 1.5, the function is declining.

This choice is the best one.

since, it is obvious from the graph that the function declines for x<1.5.

Answer:

Step-by-step explanation:

Carl is boarding a plane. he has 2 checked bags of equal weight and a backpack that weighs 4kg. The total weight of Carls baggage is 35 kg.

2w + 4= 35

2w=31

w= 31/2

w=15.5

The weight of each bag is 15.5 kg.

To solve this problem, we can use the formula for probability:

Probability = (Number of favorable outcomes) / (Total number of outcomes)

A. To find the probability that a student likes vanilla or chocolate ice cream, but not both, we need to subtract the number of students who like both from the total number of students who like vanilla or chocolate:

Number of students who like vanilla or chocolate = 258 + 142 = 400

Number of students who like both = 102

Number of students who like only vanilla or only chocolate = 400 - 102 = 298

Probability = 298/300 = 0.9933

B. To find the probability that a student likes neither vanilla nor chocolate ice cream, we need to subtract the total number of students who like either or both flavors from the total number of students:

Total number of students = 300

Number of students who like vanilla or chocolate = 258 + 142 = 400

Number of students who like both = 102

Number of students who like neither flavor = 300 - 400 + 102 = 2

Probability = 2/300 = 0.0067

C. To find the probability that a student likes vanilla ice cream but not chocolate ice cream, we need to subtract the number of students who like both from the total number of students who like vanilla:

Number of students who like vanilla = 142

Number of students who like both = 102

Number of students who like only vanilla = 142 - 102 = 40

Probability = 40/300 = 0.1333

cot θ = 7/4 and θ in degrees = 29.744881 degrees. In this case, the adjacent side is 7 and the opposite side is 4.

Cotangent (cot) is the ratio of the adjacent side to the opposite side of a right triangle.

In this right angle triangle, cot θ can be calculated using the formula

cot θ = adjacent/opposite.

In this case, the adjacent side is 7 and the opposite side is 4.

Therefore, cot θ = 7/4.

Now, to find theta in degrees, we can use the inverse cotangent function, arccot.

arccot (cot θ) = θ.

Therefore, θ = arccot (7/4).

Using a calculator, arccot (7/4) = 29.744881 degrees

Therefore, cot θ = 7/4 and θ in degrees = 29.744881 degrees.

Answer:

  40°

Step-by-step explanation:

You want the measure of ∠LNO, marked as y°, given the two vertical angle pairs {100°, (x -y)°} and {y°, 2/7x°}.

Vertical angles have the same measure, so we can write the equations ...

We want the value of y, so it makes sense to solve these equations using a method that eliminates x. Rewriting the second equation to solve for x, we have ...

  x° = 7/2y°

Substituting this into the first equation gives ...

  100° + (7/2y -y)°

  100° = 5/2y°

  2/5(100) = y° = 40°

The measure of ∠LNO is 40°.

If the scooter travels 4.4km with the given radius, the wheel have number of revolutions about 1567 times.

In order to solve this issue, we must first determine the scooter wheel's circumference, which is given by the formula C = 2[tex]\pi[/tex]r, where r is radius of the wheel. Hence, the circumference of a wheel with a 14 cm radius would be:

C = 2[tex]\pi[/tex](14cm) = 28[tex]\pi[/tex] cm

We must translate the distance from kilometres to centimetres in order to determine how many revolutions the wheel completes if the scooter travels 4.4 kilometres. 1 km equals 100,000 cm, so 4.4 km is equal to 440,000 cm.

Now, we can calculate the number of rotations by dividing the distance travelled by the wheel's circumference:

Distance travelled divided by circumference equals the number of revolutions.

440,000 cm / 28 cm divided by the number of revolutions

1566.99 revolutions were made.

Therefore if the scooter travels 4.4km, the wheel will turn about 1567 times.

Assumptions for above case:

1-Equal payments are made monthly.

2-Total amount deposited throughout the year are compounded by end of the year.

3-Annual interest is 6%

4-Total Amount invested plus interest at maturity are reinvested the following year.

Given above, if you create a table in excel for those calculations, you would get $296.330 /month which amounts to $12,000.00 in 3 years approximately.

Year 1 = $3,555.96 Pre-interest =>$3769.32 Post 6% interest

Year 2 = $7,325.28 Pre-interest =>$7,325.28 Post 6% interest

the area of a rectangle is

length × width.

so, the original area is

40 × 21 = 840 cm²

now, we add x to length and width, and we get :

(40 + x) × (21 + x) = 2262 cm²

let's do the multiplication :

40×21 + 40x + 21x + x² = 2262

840 + 61x + x² = 2262

x² + 61x = 1422

x² + 61x - 1422 = 0

a quadratic equation

ax² + bx + c = 0

has the general solution

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

a = 1

b = 61

c = -1422

x = (-61 ± sqrt(61² - 4×1×-1422))/(2×1) =

= (-61 ± sqrt(3721 + 5688))/2 =

= (-61 ± sqrt(9409))/2 =

= (-61 ± 97)/2

x1 = (-61 + 97)/2 = 36/2 = 18

x2 = (-61 - 97)/2 = -158/2 = -79

x2 would make the side lengths negative, and that does not make any sense for an actual shape, so

x = 18

is our valid solution.

that means the new length is

40 + 18 = 58 cm

the new width is

21 + 18 = 39 cm

The length of BC is 16cm, the length of AB is 8√3cm, and the length of AC is 8cm. In a right triangle, the side opposite the right angle is the hypotenuse, while the other two sides are the legs.

Let's label the sides of the triangle ABC as follows:

BC is the hypotenuse, opposite to the right angle at B.

AB is a leg, adjacent to the angle A.

AC is a leg, opposite to the angle A.

Given that the area of the triangle is 32√3cm^2, we have:

(area) = (1/2) x (base) x (height)

Substituting the values we know, we get:

32√3 = (1/2) x AB x AC

Simplifying, we get:

AB x AC = 64√3

We also know that <A = 30 degrees, which means that <C = 60 degrees (since the angles in a triangle add up to 180 degrees).

Now we can use the trigonometric ratios to find the lengths of the sides. We have:

sin(30) = AC/BC

cos(30) = AB/BC

Solving for AC and AB, we get:

AC = BC x sin(30) = BC/2

AB = BC x cos(30) = BC√3/2

Substituting these values into the equation we got earlier, we get:

(BC/2) x (BC√3/2) = 64√3

Simplifying, we get:

BC^2 = 256

Taking the positive square root, we get:

BC = 16

Substituting this value into the equations we got for AB and AC, we get:

AB = BC√3/2 = 8√3

AC = BC/2 = 8

Therefore, the length of BC is 16cm, the length of AB is 8√3cm, and the length of AC is 8cm.

so,

length×width = 48 cm²

2×length + 2×width = 28 cm

length + width = 14 cm

length = 14 - width

we use this in the first equation :

14×width - width² = 48

-width² + 14×width - 48 = 0
