80
<span>Using the rule of 3, 60x100% =6000(obviously) and 6000/75 = 80</span>
2(30)=60+30=90. thats a right angle which is 90 degrees so the answer is 30
The value of f –1(13) is 4
<h3>How to determine the inverse value?</h3>
The table of values is given as:
x –4 0 2 5 9 13
f (x) –11 1 7 16 28 40
A linear function is represented as:
y = mx + b
Where b represents the y-intercept and m represents the slope
From the graph, when x = 0, y = 1.
This means that b = 1
So, we have
y = mx + 1
Also from the graph, when x = 2, y = 7.
So, we have:
7 = 2m + 1
Subtract 1 from both sides
7 - 1 = 2m + 1 - 1
Evaluate the difference
6 = 2m
Rewrite the above equation as:
2m = 6
Divide both sides of the equation by 2
m = 3
Substitute m = 3 in y = mx + 1
y = 3x + 1
The notation f –1(13) implies that y = 13
So, we have
13 = 3x + 1
Subtract by 1
3x = 12
Divide by 3
x = 4
Hence, the value of f –1(13) is 4

Answer:
2nd option
Step-by-step explanation:
Using the rule of exponents/ radicals
⇔ ![(\sqrt[n]{a}) ^{m}](https://tex.z-dn.net/?f=%28%5Csqrt%5Bn%5D%7Ba%7D%29%20%5E%7Bm%7D)
, then
= ![(\sqrt[4]{10}) ^{3x}](https://tex.z-dn.net/?f=%28%5Csqrt%5B4%5D%7B10%7D%29%20%5E%7B3x%7D)
