Answer:
8%
Step-by-step explanation:
Motivation to learn represents a 40% of the learning acquired and its rated from 1 to 10. An increase from 7 to 9 represents an increase (of motivation to learn of 20%) But since this quality represent 40% of the total, the real increase in learning is 0.2*0.4=0.08 or 8%.
Let the battery life = X
then 9.54% of X = 1.908
solve for X. <span>9.54% is very close to 1/10. So you can estimate which of the choices comes nearest to 1.908 by finding one tenth of each choice. Then check the choice by multiplying its value by 0.0954 to see if you get 1.908. Phone B which is 25.

Answer:
x= 32 ± √29
Step-by-step explanation:
x² - 8x - 13 = 0
ax² + bx + c = 0
Comparing equations we get,
a=1
b=(-8)
c=(-13)
Using quadratic formula,
________
x= b² ± √ b²-4ac
—————————
2a
Substituting the values
__________
x= 64 ± √( 64 + 52)
______________
2
= 32 ± √29
Hope this answer helps you....
Answer:
1) f(x) = x/8 - 7
2) f(x) = 1 - x/3
3) f(x) = 20 - 0.25x
4) f(x) = x + 7
Step-by-step explanation:
f^-1 = 8(x + 7)
x + 7 = y/8
x = y/8 - 7
f(x) = x/8 - 7
f^-1 = -3(x - 1)
y/-3 = x - 1
x = 1 - y/3
f(x) = 1 - x/3
f^-1 = 4(20 - x)
y/4 = 20 - x
x = 20 - y/4
f(x) = 20 - x/4
f(x) = 20 - 0.25x
f^-1 = x - 7
y = x - 7
x = y + 7
f(x) = x + 7
Answer:
I think 4
Step-by-step explanation:
If FG = 2 and EF looks very similar, EG would be 4 and EH=8, 8-4=4
