Answer:

$34.56

Step-by-step explanation:

First, find the discount price.

20% of 40

20/100 x 40= $8

Deduct the discount from the original price.

40 - 8 = $32

This is the discount price.

Now, find 8% (tax) of the price.

8/100 x 32 = $2.56

Add it to the price.

32 + 2.56 = $34.56

Hope this helps!

Three functions are given below: f(x), g(x), and h(x).

Rzqust [24]

Answer: The axis of symmetry is x=1.

Explanation:

The given function is,

$g(x)=5x^2-10x+7$

The degree of the equation is 2. SInce it is a quadratic function therefore the graph of the function is a parabola.

The axis of symmetry of a parabolic function $f(x)=ax^2+bx+c$ is a vertical line,

$x=-\frac{b}{2a}$

Since the value of a is 5m b is -10 and c is 7, So the axis of symmetry is,

$x=-\frac{(-10)}{2(5)}$

$x=\frac{10}{10}$

$x=1$

Therefore, the axis of symmetry is x=1.

Suppose that the world's current oil reserves is

SOVA2 [1]

Answer:

A) R = 1900 -24t

B) 1684 billion barrels

C) 79.17 years

Step-by-step explanation:

Reserves start at 1900 billion barrels and decrease by 24 billion barrels each year. The value for t=0 is 1900; the value for t=1 is 24 less.

R = 1900 -24t

For t=9, the reserves will be ...

R = 1900 -24(9) = 1900 -216 = 1684 . . . . billion barrels

The reserve will be 0 when ...

0 = 1900 -24t

24t = 1900 . . . . . add 24t

t ≈ 79.17 . . . . divide by 24

Reserves will be gone in about 79.17 years.
