Hello,
To solve this function for f(4) we need to plug 4 into f(x) and the result will be our answer. We know that f(x) is

. Plugging in 4 we get

. Therefore, f(4)=41. Hope this helps!
Answer:
The volume of the rectangular prism is 
Step-by-step explanation:
A rectangular prism is in the shape of cuboid which has three dimensions i.e Length, width and height.
Given: Length =8.5 cm width= 3.2 cm and Height= 6 cm
The volume of a Cuboid = 
Applying the given dimensions in the formula:
The volume of a Cuboid= 
= 
The volume of the rectangular prism is 
Answer:
No because one is negative and the other one is positive
Step-by-step explanation:
Answer:
y = 10
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin30° =
, then
sin30° =
=
=
( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
Answer:
w = 36
Step-by-step explanation:
You can make a ratio 98 : 84 = 42 : w

49w = 1764
w = 36
