In looking for f(g(x)), one has to substitute the expression of g(x) in place of the variable "x" in f(x). This is shown below:
Given:
f(x) = 9x - 2
g(x) = -x + 3
f(g(x)) = 9(-x + 3) - 2
f<span>(g(x)) = -9x + 27 - 2
</span>f<span>(g(x)) = -9x + 25</span>
Answer:
- 13
Step-by-step explanation:
Plug 3 in for x:
-5(3)+2
Simplify :
-15+2
=-13
Vsphere=(4/3)pir³
d/2=r
d=6.2
6.2/2=r=3.1
vsphere=(4/3)pi3.1³
vsphere=(4/3)pi29.791
Vsphere=124.72498666666666666666666666667
answer is 124.72498666666666666666666666667 cubic feet
or rounded to neares whole, 125 square feet
Answer:
The tempature decreased or "dropped" 15 degrees.
Step-by-step explanation:
Answer:
24 yards
Step-by-step explanation:
Circumference is πd where d is the diameter. You can derive this to isolate diameter by dividing both sides by π
D=C/π Now just plug the numbers for your variables.
D=75.36/3.14
D=24
The diameter is 24 yards
