Is the function f(x) = 9x2 + 4x – 2 linear, quadratic, or exponential?

Answers

Answer 1

Answer:

According to me it is quadratic function.

Answer 2

Answer

The function [tex]f(x)=9x^2+4x-2[/tex] is a quadratic function.

Linear functions

Linear functions are the functions having the highest power as one, whereas the quadratic functions have two as the highest power. On the other hand, the function which has the form of [tex]f(x)=\text{e}^x[/tex] is known as an exponential function.

How to determine whether the function is quadratic or not?

The function [tex]f(x)=9x^2+4x-2[/tex] has the highest power of [tex]2[/tex].

Thus, the function [tex]f(x)=9x^2+4x-2[/tex] is a quadratic function.

Answer:

64 pretzels = 16 oz

16 pretzels = 4 oz

1  pretzel = .25 oz

4 pretzels = 1 oz

Step-by-step explanation:

If you know that 64 equals 16 ounces than you can divide 64 by 16 to get 4. This means that one ounce equals four pretzels. Then you can multiply 1 oz by 4 and 4 pretzels by 4 to get 16 pretzels that equal 4 oz. If 4 pretzels equals 1 oz then 1 pretzel equals 1 oz divided by 4.

Jimmy bought a refrigerator that cost $525 before tax. He paid 8% of this amount in tax. What was the total cost of the refrigerator including tax?

Answers

Answer:

$567 after tax

Step-by-step explanation:

first, let's multiply 525 by 0.08 because he paid 8% (0.08) of 525 in tax.

525(0.08)= 42

now, let's add them together, because the question asks for the total cost.

525+42=567

$567 after tax

Which expression could be used to determine the perimeter of the triangle?

A 9x + 4
B 9(x + 4)
C 13x
D 13(x + 1)

Answers

Answer:

A. 9x + 4

Step-by-step explanation:

Perimeter of a triangle = side A + side B + side C

Side A = 2.5x + 3

Side B = x + 6

Side C = 5.5x - 5

Perimeter of a triangle = side A + side B + side C

= (2.5x + 3) + (x + 6) + (5.5x - 5)

= 2.5x + 3 + x + 6 + 5.5x - 5

= 2.5x + x + 5.5x + 3 + 6 - 5

= 9x + 4

Perimeter of a triangle = 9x + 4

The correct answer is A. 9x + 4

Answers

Answer:

=72(pi) × h

226.194671059 × h = 4750.1

h = 21 feet
