Answer: The surface area of the rectangular prism is 140 and 3/16 square centimeters.

To find A, we need to take the derivative of the given function:

ddx[−−17.6sin(34.4−5.2x)] = −5.2*17.6cos(34.4−5.2x)

= −91.52cos(34.4−5.2x)

Comparing with the given function:

AcosB = −91.52cos(34.4−5.2x)

Therefore, A = |-91.52| = 91.52

Hence, A is 91.52.

The value of the numeric expression 1/3+1/4➗2/4 is given as follows:

5/6.

The numeric expression in the context of this problem is defined as follows:

1/3+1/4➗2/4.

The division operation takes precedence over the addition operation, hence:

(1/4)/(2/4) = 1/2 -> as we can simplify the denominator of 4 for both the factors, leaving with a quotient of 1/2.

Then the expression is given as follows:

1/3 + 1/2.

The least common factor of 2 and 3 is of six, hence the result of the sum is given as follows:

1/3 + 1/2 = (2 + 3)/6 = 5/6.

The tension in cable B is 400 N.

What is tension in cable ?

Tension is the force transmitted through a string, rope, cable, or wire when it is pulled taut by forces acting from opposite ends. It is the pulling force that exists between two objects that are connected by a rope or cable and is usually measured in newtons (N) or pounds (lbs). The tension in a cable or rope can be calculated using the principles of equilibrium, where the sum of the forces acting on the object is equal to zero. In other words, the tension in a cable is the force that must be applied to the cable in order to keep it taut and maintain its position or prevent it from breaking.

According to the question:
To solve this problem, we need to use the fact that the sum of the forces acting on the sign must be zero in order for the sign to be in equilibrium. We can break down the weight of the sign into its components parallel and perpendicular to the cables:

F_parallel = 800 N * sin(30°) = 400 N

F_perpendicular = 800 N * cos(30°) = 693.2 N

The tension in cable A must balance the perpendicular component of the weight of the sign, so we have:

Tension_A = 693.2 N

The tension in cable B must balance the horizontal component of the weight of the sign, so we have:

Tension_B = 400 N

Therefore, the tension in cable B is 400 N.

Answer:

[tex]h(0) = -16(0)^2 + 128[/tex]

[tex]= 128[/tex]

Therefore, the rocket goes to a maximum height of 128 feet.

4. The axis of symmetry of the parabolic path of the rocket is the vertical line that passes through the vertex of the parabola. Since the coefficient of [tex]t^2[/tex] is negative, the parabola opens downwards, and the vertex represents the maximum point of the path. As we found in question 2, the time at which the maximum height occurs is t = 0, so the axis of symmetry is the vertical line passing through t = 0.

5. To find when the rocket hits the ground, we need to find the time t at which h(t) = 0. Substituting [tex]h(t) = -16t^2 + 128[/tex], we get:

[tex]-16t^2 + 128 = 0[/tex]

Solving for t using the quadratic formula, we get:

t = (0 ± √(0^2 - 4(-16)(128))) / (2(-16))

= (±√8192) / (-32)

= ±8

Since time cannot be negative, the rocket hits the ground after approximately 8 seconds.

6. To find how high the rocket is at t = 2 seconds, we can substitute t = 2 into the equation h(t) = -16t^2 + 128:

h(2) = -16(2)^2 + 128

= -64 + 128

= 64 feet

Therefore, the rocket is at a height of 64 feet at 2 seconds.

7. To find when the rocket is at a height of 252 feet, we need to solve the equation [tex]-16t^2 + 128 = 252[/tex]. Rearranging and solving for t, we get:

[tex]-16t^2 + 128 = 252[/tex]

[tex]-16t^2 = 124[/tex]

[tex]t^2 = -124/-16[/tex]

t^2 = 7.75

t ≈ ±2.78 seconds

Since time cannot be negative, the rocket is at a height of 252 feet after approximately 2.78 seconds.

8. The graph coordinates of the rocket's path can be plotted using the function [tex]h(t) = -16t^2 + 128[/tex]. The x-axis represents time t in seconds and the y-axis represents the height of the rocket in feet. We can plot points on the graph by substituting different values of t into the equation and plotting the resulting height. For example, some common points to plot include the vertex at (0, 128), the point where the rocket hits the ground at approximately (8, 0), and the point where the rocket is at a height of 252 feet at approximately (2.78, 252). We can also plot other points by substituting different values of t into the equation and plotting the resulting height.

The x-intercept of the equation is (16, 0), which means that after 16 hours of driving, Xavier will have used up all the gas in his tank.

To find the x-intercept of the equation G = 12 - 0.75t, we need to set G = 0 and solve for t:

0 = 12 - 0.75t

0.75t = 12

t = 16

As a result, the equation's x-intercept is (16, 0), indicating that Xavier will run out of gas after 16 hours of driving.

The x-intercept in the problem denotes the moment at which Xavier runs out of gas and his car comes to a complete stop. This is a crucial factor to take into account when organising a lengthy road trip because it shows how long Xavier can travel before needing to refuel.

There are 90 distinct arrangements of the letters in SPINNING.

In mathematics, permutation refers to the arrangement of objects in a specific order. A permutation of a set of objects is an ordered arrangement of those objects. For example, if we have a set of three objects {A, B, C}, then the permutations of this set would be {ABC, ACB, BAC, BCA, CAB, CBA}. The number of permutations of a set of n objects is denoted by n!. Permutations are commonly used in combinatorics, probability theory, and other areas of mathematics and science.

In the given question,

The word SPINNING has 8 letters, out of which two letters appear twice.

Let's first consider the distinct arrangements of the 6 unique letters (ignoring the repeated letters).

There are 6! ways to arrange these 6 letters in a row.

However, we need to adjust for the repeated letters. The letter "N" appears twice, so we divide by 2! to account for the fact that the two N's can be arranged in 2! = 2 ways without changing the arrangement of the other letters. Similarly, the letter "I" also appears twice, so we divide by another 2!.

Therefore, the total number of distinct arrangements of the letters in SPINNING is:

6! / (2! x 2!) = 360 / 4 = 90.

So there are 90 distinct arrangements of the letters in SPINNING.

In the function k(x) = 3(2^(-8x)), the domain is all real numbers (-∞, +∞) and the range is all positive real numbers (0, +∞).

Hi! I'd be happy to help you find the domain and range of the function k(x) = 3(2^(-8x)). The domain of a function is the set of all possible input values (x-values) for which the function is defined, while the range is the set of all possible output values (y-values) that the function can produce.

For k(x) = 3(2^(-8x)), the function is an exponential function, and exponential functions are defined for all real numbers. This means that you can input any real number value for x, and the function will produce a valid output. Therefore, the domain of k(x) is all real numbers, which can be represented as (-∞, +∞) or R.

To find the range, we need to consider the behavior of the exponential function as x increases and decreases. As x goes to negative infinity, 2^(-8x) approaches infinity, and thus 3(2^(-8x)) also approaches infinity. As x goes to positive infinity, 2^(-8x) approaches 0, but since we are multiplying by 3, the minimum value of k(x) is 0. However, the function never actually reaches 0, so the range is all positive real numbers, which can be represented as (0, +∞).

Answer: the radius of the circle is 14 cm. :)

Step-by-step explanation:

To find,

The radius of the circle.

Solution,

The radius of the circle will be 14 cm.

We can easily solve this problem by following the given steps.

According to the question,

Length of a rectangular wire = 32 cm

The breadth of a rectangular wire = 12 cm

This wire is bent into the shape of a circle.

So,

The perimeter of the rectangle = Circumference of the circle

We know the formula for the perimeter of a rectangle is as follows:

P = 2(Length+Breadth)

P = 2(32+12) cm

P = 2(44) cm

P = 88 cm

We know that the formula to find the circumference of the circle is given as follows:

C =

2πr = 88 cm

2×22r/7 = 88

44r/7 = 88

Using the cross multiplication method,

44r = (88×7)

r = (88×7)/44

r = (2×7) cm

r = 14 cm

Hence, the radius of the circle is 14 cm.

Answer:

14.01 cm

Step-by-step explanation:

The length of the wire is equal to the perimeter of the rectangle. So, the length of the wire is:

When this wire is bent into a circle, its length becomes equal to the circumference of the circle. The formula for the circumference of a circle is:

(let r = radius)

2 × π × r

So, we can write:

Solving for r, we get:

So, the exact value of the radius of the circle formed by bending this rectangular wire is 14.01 cm.

You do not use lines to connect the dots.

Therefore after rewrite the expression we get 1/33 = 27.

Define negative exponent?

A negative exponent in mathematics means that the exponent's base needs to be divided by one or more. For instance, the equivalent of the mathematical expression 3-2 is:

1 / (3²) = 1/9

We can use the rule: to rewrite 1/3-3 without an exponent.

a⁻ⁿ = 1/aⁿ

where n is a positive integer and an is a non-zero number.

The reciprocal of the base raised to a positive exponent can also be used to write negative exponents. For instance:

3⁻ = (1/3²) = 1/9

In scientific notation, where numbers are written as powers of 10, negative exponents are frequently utilized

When we change this rule's 3-3 to:

3⁻³ = 1/3³

As a result, 1/3-3 can now be written as:

1/3⁻³ = 1/(1/3³)
