Answer:
<h2>8 or -8</h2>
Step-by-step explanation:
The absolute value of number a:
|a| = a for a ≥ 0
|a| = -a for a < 0
|a| = 8 ⇔ a = 8 or a = -8

Answer:
106 m
Step-by-step explanation:
The law of sines is useful.
The angle opposite the given side of 50 m is ...
180° -83° -69° = 28°
Then the distance (d) opposite the 83° angle is ...
d/sin(83°) = (50 m)/sin(28°)
d = (sin(83°)/sin(28°))×(50 m) = 105.709 m
The ball is about 106 meters from the pin.
In the table, it shows the x values and the corresponding y values under it [aka f(x)].
The problem is basically asking which equation, a,b,c or d will get the y values with the x values.
we can try this with x value 3 and y value 7
a. 3^x=3^3=3*3*3=27
27 is so far away from 7 so a must be wrong
b.3x=3*3=9
still not 7 therefore b is also wrong
c. 2^x-1= 2^3-1=8-1=7
7=7 therefore this one might be right, but to make sure we have to check if d is correct or not
d. 2x+1=2*3+1=7
7=7 so d is also correct for the first set of values.
Next we should use the next available values until one of the answers c or d is confirmed wrong
x value 4 and y value 15
c. 2^4-1=16-1=15
15=15
d. 2x+1=8+1=9
9 does not work
Therefore, the answer should be c.
