Answer:

A' (8,-7)

B' (8,-7)

When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative

Which of the following equations could be solved to determine the length of RS?
stich3 [128]

Answer:

\frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}

Step-by-step explanation:

Given:

S = 52.5°

s = QR = 7

Q = 80°

q = RS = ?

Required:

Equation that could be used to find the length of RS

Solution:

We would need the law of Sines which is given as:

\frac{Sin(A)}{a} = \frac{Sin(B)}{b} = \frac{Sin(C)}{c}

Applying the Law of Sines, we would have the following equation:

\frac{Sin(Q)}{q} = \frac{Sin(S)}{s}

Plug in the values

\frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}

Therefore, the equation that can be used to determine the length of RS is \frac{Sin(80)}{RS} = \frac{Sin(52.5)}{7}

In the first week of​ July, a record 1,060 people went to the local swimming pool. In the second​ week, 100 fewer people went to
vovikov84 [41]

(Can I have Brainlist?)

Answer:

10%

Step-by-step explanation:

The following information can be gotten from the question regarding the number of people that went to the swimming pool are:

First week of July = 1020

Second week = 1020 - 100 = 920

Third week = 920 + 130 = 1050

Fourth week = 1050 - 132 = 918

The percentage decrease over the four weeks will be:

= (1020 - 918)/1020 × 100

= 102/1020 × 100

= 10%
