Answer:

The answer is $28.56

Step-by-step explanation:

To find the 2% sales tax, you need to multiply the 2% or 0.02 by 28.

Doing this will give you 0.56.

Then you add 0.56 to 28 to get 28.56, hence, $28.56 is the total cost.

Hope it helps!

Find the length of RS with endpoints R(4,5) and S(-1, – 4).

Artist 52 [7]

Answer:

$d=\sqrt{106}$

Step-by-step explanation:

Distance Formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Simply plug in your 2 coordinates into the distance formula to find distance <em>d</em>:

$d=\sqrt{(-1-4)^2+(-4-5)^2}$

$d=\sqrt{(-5)^2+(-9)^2}$

$d=\sqrt{25+81}$

$d=\sqrt{106}$

Find x in the triangle below. Round your answer to the nearest tenth.

jonny [76]

Answer:

Step-by-step explanation:

Remark

x is opposite the 90 degree angle. It is the hypotenuse.
13 makes up the 57 degree angle. It is the side adjacent.
The adjacent side and the hypotenuse define the cos(theta).

Formula

cos(theta) = adjacent side / hypotenuse

Givens

Theta = 57 degrees

Hypotenuse = x

Side adjacent = 13

Solution

Cos(57) = 13 / x Multiply both sides by x
x*cos(57) = 13 Divide by cos(theta)
x = 13/cos(57)
x = 13 / cos(57)
cos(57) = 0.5446
x = 13/ 0.5446
x = 23.87
