(24.7C) The area of a rectangle is equal to x2 +
16x + 55 square units. If the length of the
rectangle is equal to x + 11 units, what expression
represents its width?
Answers
Answer:
x + 5
Step-by-step explanation:
A = LW
W = A/L
W = (x^2 + 16x + 55)/(x + 11)
W = [(x + 11)(x + 5)]/(x + 11)
W = x + 5

The x-intercepts of the function f(x) are:
Left x-intercept: (-3, 0)
Right x-intercept: (7, 0)
Given is a function, f(x) = -2(x + 3)(x - 7).
We need to find the x-intercept of the function,
To find the x-intercepts of the function f(x), we set f(x) equal to zero and solve for x:
-2(x + 3)(x - 7) = 0
Now, we can use the zero product property, which states that if a product of factors is equal to zero, then at least one of the factors must be zero.
So, we have two cases to consider:
Case 1: x + 3 = 0
Solving this equation, we subtract 3 from both sides:
x = -3
Case 2: x - 7 = 0
Solving this equation, we add 7 to both sides:
x = 7
Therefore, the x-intercepts of the function f(x) are -3 and 7.
Writing them as ordered pairs, we have:
Left x-intercept: (-3, 0)
Right x-intercept: (7, 0)

In this figure, angles R and S are complementary. Find the measure of angle S.
Answers
Answer:
S = 28 degrees
Step-by-step explanation:
The given angles are R = 62 and Q = 90 since there's the square showing its a right angle.
It says that R and S are complimentary which means together their total is 90 degrees. So there are two ways to do this;
R + S = 90
62 + S = 90
-62 -62
S = 28
OR
R + S + Q = 180
62 + S + 90 = 180
152 + S = 180
-152 -152
S= 28
Answer:
The answer I got was 28°
Step-by-step explanation:
1. Triangles add up to 180°
2. The "square" in the triangle means that angle is equal to 90°
3. Add the 90° angle with the 62° angle
4. Subtract the answer (152°) from the total (180°)
5. The answer is 28°

Find all values of 1 for which the ball's height is 11 meters.

Answers
Answer:
The ball height is 11 meters at t = 0.59 seconds and t = 3.41 seconds.
Step-by-step explanation:
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
The height of the ball after t seconds is given by:
[tex]h(t) = 1 + 20t - 5t^2[/tex]
Find all values of t for which the ball's height is 11 meters.
This is t for which [tex]h(t) = 11[/tex]. So
[tex]h(t) = 1 + 20t - 5t^2[/tex]
[tex]11 = 1 + 20t - 5t^2[/tex]
[tex]5t^2 - 20t + 10 = 0[/tex]
Simplifying by 5
[tex]t^2 - 4t + 2 = 0[/tex]
Which means that [tex]a = 1, b = -4, c = 2[/tex]
[tex]\Delta = (-4)^2 - 4(1)(2) = 8[/tex]
[tex]t_{1} = \frac{-(-4) + \sqrt{8}}{2} = 3.41[/tex]
[tex]t_{2} = \frac{-(-4) - \sqrt{8}}{2} = 0.59[/tex]
The ball height is 11 meters at t = 0.59 seconds and t = 3.41 seconds.

How to calculate the volume of the square pyramidFrom the question, we have the following parameters that can be used in our computation:
The figure
The volume of the square pyramid is calculated as
Volume = 1/3 * Base area * Height
using the above as a guide, we have the following:
Base area = 14 * 14
Base area = 196
Also, we have
Height = 22
Substitute the known values in the above equation, so, we have the following representation
Volume = 1/3 * 196 * 22
Evaluate
Volume = 1437.33
Hence, the volume of the pyramid is 1437.33 cubic cm
