Answer:
x = -3
Step-by-step explanation:
4x - 8 = -4 (11 + 2x) (distribute the -4 to the numbers in the parenthesis)
4x - 8 = -44 + -8x (add 8x on both sides)
12x - 8 = -44 (add 8 on both sides)
12x = -36 (divide both sides by 12)
x = -3

Step-by-step explanation:
Sakura's house is at an elevation between 113 m and 120 m above sea level. Her friend Ted lives about 15 m below her. Choose the compound inequality that describes the elevation x of Ted's house. Part B Ted lives between _____m and _______m above sea level.
The compound inequality to describe the elevation of Ted's house is 135 > x > 128.
Ted lives between 128m and 135m above sea level.
How to explain the inequality?Now it is given that,
Sakura's house is at an elevation between 113 m and 120 m above sea level.
Let x be the elevation of Sakura's house.
So, 120 > x > 113
Now Ted lives about 15 m below her
Ted's house elevation = x - 15
So, the compound inequality to describe the elevation of Ted's house,
120 > x - 15 > 113
Adding 15 to the inequality we get,
120 + 15 > x - 15 + 15 > 113 + 15
Solving we get,
135 > x > 128
This is the required compound inequality.
Thus, the compound inequality to describe the elevation of Ted's house is 135 > x > 128.

2. A rocket is launched from rest, at ground level. The graph of the rocket's velocity with respect to
time looks as follows: y= 0.15x2
How fast is the rocket traveling after 15 seconds?
Insert the graph picture here:
Graph please
Answer:
y = 33.75 m/s.
Step-by-step explanation:
The graph of the rocket's velocity with respect to time looks as follows :
[tex]y=0.15x^2[/tex] ...(1)
Where x is time in seconds
We need to find the velocity of rocket after 15 seconds. Put x = 15 in equation (1).
[tex]y=0.15\times (15)^2\\\\=33.75\ m/s[/tex]
Hence, the speed of the rocket after 15 seconds is 33.75 m/s.
Find the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4].
The average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is 111.
According to the given question.
We have a function g(x) = 7x^2 + 8x^3.
And a interval [-3, 4].
As we know that, the average rate of change of y over an interval between 2 points (a, f(a)) and (b, f(b)) is the slope of the secant line connecting the 2 points.
To calculate the average rate of change between the 2 points we use the formula
f(b) - f(a)/ b - a
Therefore, the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is given by
[7(4)^2 + 8(4)^3 - 7(-3)^(2) - 8(-3)^3]/4 + 3
= [112 + 512 - 63 + 216]/7
= 777/7
= 111
Hence, the average rate of change of g ( x ) = 7 x 2 + 8 x 3 on the interval [-3, 4] is 111.

Answer:
D) 41.81 degrees
Step-by-step explanation:
In this problem, we are given a leg length (a=12) and the hypotenuse (c=18).
We need to select which trigonometric identity to use with the acronym SOHCAHTOA:
SOH -> sine=opposite/hypotenuse
CAH -> cosine=adjacent/hypotenuse
TOA -> tangent=opposite/adjacent
Given side a is opposite of angle A and side c is the hypotenuse, we clearly need to use the sine function.
Set up an equation based on the information you have:
sin(A)=12/18
Now take the inverse:
sin^-1(sin(A))=sin^-1(12/18)
A=41.8103149
So the best option is answer D) 41.81 degrees
