Answer:
the last two
Step-by-step explanation:
Answer: f(g(x))= -2x+43
Step-by-step explanation:
Here, you would start by substituting the equation for g(x) into the x value of f(x) equation.
Since g(x)=1/4x+5, f(g(x)) would be:
f(g(x))= 3-8(1/4x+5)
Then you would simplify.
f(g(x))= 3-8(1/4x+5)
= 3-2x+40
=-2x+43
I would say 8:00 between 6:00 and 10:00 cause it seems to be progressing in increments of 2 hours
Answer:
A) 300 cm2
Step-by-step explanation:
First you have to find height
use Pythagorean theorem: a2 + b2 = c2
![h^{2}+ 8^{2} = 17^{2}](https://tex.z-dn.net/?f=h%5E%7B2%7D%2B%208%5E%7B2%7D%20%3D%2017%5E%7B2%7D)
h2 + 64 =289
h2 = 289-64
h2 = 225
h= 15
now the area
A = a * h
A = 20 * 15
A = 300 cm2
Answer:
It will take Malik 23.157 additional hours of work to save total of $320 into his savings. Which is $220 of what he needs to match Linda.
Malik will work total 23.157 + 10.526hrs = 33.683 to save $320
Linda will work 45.714 hrs to save $320.
Step-by-step explanation:
Linda - $320 / 7hr rate = 45.714 hours worked to earn this amount.
Find out how many hours Malik worked to save $100 first.
$100 current savings divided by his hourly rate of $9.50 = 10.526 hours worked.
To find out how many hours Malik must work to have $320 in his account, we subtract what he has now $100 from what he needs $220 to match with Linda's $320. Next find how many hours it will take for Malik to save $220.
To get this take $220 / 9.5 hr rate which is what he gets paid per hour to get 23.157.
