Answer:

 =22.47

Step-by-step explanation:

We are buying 2 shirts

Before discount  2*15 = 30

We get 30% off.  That means we pay 70 percent of the price

$30 * 70% =

30 *.7

21

The cost of the shirts before tax is 21 dollars

Tax is the cost of the shirts after discount  times the tax rate

tax = 21 * 7%

tax = 21 *.07

tax =1.47

We add the tax to the cost of the shirts

Final cost = discount price + tax

                =21+1.47

                =22.47

Will mark brainliest!!!!!!! Please help!! 18 points for right answer!

I think it should be 1.7?

a^2 + b^2 = c^2

c^2 = 16

Square root of 16 is 4.

1 + 3 = 4

Square root of 1 is 1 and square root of 3 is given, which is 1.7.

An equilateral has two right triangles out together, so basically that would be a rectangle.

1 x 1.7 = 1.7

For the graph of the function below, identify the axis of symmetry, vertex and formula for the function
zhannawk [14.2K]
Well the first obvious thing is that the axis of symmetry is 0.5, so we can automatically cross out (C).

All the answers have the correct vertex, so lets find the formula for the function.

Fortunately, from my point of view, I can see two points that have their coordinates as integers, (-1, -3) and (2, 3), we can plug these into the already given "formulas" in the options (A), (B), and (D).

Out of the three choices, the formula in option (D) satisfies both coordinates, thus option (D) is correct.
