32 divided by -2 equals -16. c:
So here, you just put in the value inside the parenthesis of the function into the actual function itself.
Here, for h(f(2)), the first one to put in is the one in f, which is 2.
Since f(x) = 3*2^x, and since x here is equal to 2, (because h(f(2)), we can just put in the 2 in place of the x.
3 * 2 ^ 2
And then you get:
3 * 4
Or 12.
So now you have
h(12)
Now do the same thing.
2 * 12 - 7
24 - 7
17
Answer:
y = 4
Step-by-step explanation:
2[2y-1]+5=19 (by PEDMAS, distribute parentheses first)
(2)(2y) - (2)(1) + 5 = 19
4y - 2 + 5 = 19
4y +3 = 19 (subtract 3 from both sides)
4y = 19 - 3
4y = 16 (divide both sides by 4)
y = 16/4
y = 4
Answer:
Ratio of the perimeters =3:1
Step-by-step explanation:
We have given that : Ratio of the sides of two squares is 3:1
To find : Ratio of their perimeters
Solution : Let the length of the sides are 3:1 = 3x : x
Formula of perimeter of square = 4(side)
Using the formula ,
Perimeter of 1 square = 4×3x= 12x
Perimeter of 2 square = 4×x= 4x
Ratio of the perimeter of 1 square and 2 square = 12x : 4x
= 3 : 1
