The square root parent function is:
B. F(x)= √x
Answer:
y = 25
Step-by-step explanation:
Given y = kx and k = 5 then
y = 5x ← equation of variation
When x = 5 , then
y = 5 × 5 = 25
There is no problem to solve in your picture
Answer:
x = 2.564 ( to 3 dec. places )
Step-by-step explanation:
Using the rule of logarithms
log
⇔ n logx
Given
= 62 ( take the ln of both sides )
ln
= ln 62, that is
x ln5 = ln 62 ( divide both sides by ln 5 )
x =
≈ 2.564
2,200*14=30,800
2,000*13=26,000
14+13=27
30,800+26,000=56,000
Your answer is C, 13(:
