The price of a pair of shoes is $45.90. The sales tax rate is 5%. How much sales tax do you need to pay?

Ne4ueva [31]

Multiply the price by the 5% by turning the percent into a decimal.
5% = 0.05
45.90 x 0.05 = $2.295
Which can be rounded to 2.30 if needed.

Find the length of the missing side. If necessary, round to the nearest tenth.

svetlana [45]

The pythagorean theorem states that the sum of the squares of two legs of a right triangle is equivalent to the hypotenuse.

So:

35^2 + b^2 = 40^2

1225 + b^2 = 1600

b^2 = 375

b = $\sqrt{375}$

b = 19.3649

The missing side's length rounded to the nearest tenth is Option C, 19.4

What is the range of the function f(x) = 12 − 3x for the domain {-4, -2, 0, 2, 4}?

Sphinxa [80]

Answer:

{24, 18, 12, 6, 0} is the range of the above function

Step-by-step explanation:

solution:

let, x= -4

f(-2) = 12-3*(-2)

= 12+12

=24

let,x= -2

f(-2) = 12-3*(-2)

=12+6

let,x =0

f(0)= 12-3*0

=12-0

=12

let,x=2

f(2) = 12-3*2

=12-6

let,x=4

f(4) = 12-3*4

=12-12

Q # 2 Graph TWX and it's image after a rotation of 90° counterclockwise about the origen

const2013 [10]

For a rotation of 90o: (x, y) ⇒ (–y, x)
T(3,4) ⇒⇒⇒ T'(-4,3)
W(-2,-1) ⇒⇒⇒ W'(1,-2)
x(-3,3) ⇒⇒⇒ x'(-3,-3)

Solve for f(-2) PLEASE HELPPPPP

viva [34]

Answer:

5/9

Step-by-step explanation:

f(x) = 5 * 3^x

Let x = -2

f(-2) = 5 * 3^-2

We know a^-b = 1/a^b

= 5 * 1/3^2

= 5/9
