H(x) = 3x2 - 2x + 13 h(3) [?]

Mathematics
1 answer:
kow [346]3 years ago
6 0

Answer:

25

Step-by-step explanation:

When you substitute x for 3, the new equation would be ; 3(3)(2) - 2(3) + 13

using order of operations from left to right, you would start by multiplying

3(3)(2) and 3(3) is 9, and 9(2) is 18. The next step is to multiply 2 and 3 which is 6. Once you have both groups of numbers simplified, you can plug them back in : 18 - 6 + 13 ; 18 - 6 is 12, and 12 + 13 is 25, so the answer is 25.

If 3x-y=123x−x=123, x, minus, y, equals, 12, what is the value of \frac{8^x}{2^y} 2 y 8 x ​ start fraction, 8, start superscript
nlexa [21]

Answer:

\frac{8^x}{2^y} = 4096

Step-by-step explanation:

Rules:

  1. \frac{a^m}{a^n}=a^{m-n}
  2. a^m\times a^n= a^{m+n}
  3. (a^m)^n=a^{m\times n}

Given that,

3x-y =12

Therefore

\frac{8^x}{2^y}

=\frac{(2^3)^x}{2^y}  [ since 8=2^3 ]

=\frac{2^{3x}}{2^y}   [ applying 3rd rule]

=2^{3x-y} [ applying 2nd rule]

=2^{12}   [ since 3x-y =12]

=4096

3x-13=74 solve for x
never [62]

Answer:

x=29

Step-by-step explanation:

3x-13=74

We want to solve for x, so we need to isolate it.

The first step is to add 13 to each side.

3x-13+13=74+13

3x = 87

Then we divide by 3 on each side

3x/3 = 87/3

x= 29

A cylinder has radius r and height h. a. How many times greater is the surface area of a cylinder when both dimensions are multi
kondor19780726 [428]
To find it directly

A = 2 pi r h

A is proportional to rh

factor 2

A is multiplied by 2 * 2 = 4

factor 3

3 * 3 =9

factor 5

5 * 5 = 25

factor 10 

10 * 10 = 100

(b) the increase in A by factor x is x^2

c(20)^2 = 400
