Evaluate the expression when r = 8.2 and s = –3.7. r – 2s
a. –22.94
b. 0.8
c. 4.5
d. 15.6

Answers

Answer 1

Answer: When you plug in the numbers for the integers, you get
8.2-2(-3.7)
If you multiply -2 and -3.7, you get 7.4 because the negatives cancel each other out.
If you then add 8.2, you get 15.6. So the answer is D.
Hope it Helps! :)

6. Which of the following is NOT coterminal to 337°?23 deg
697 deg
-23 deg
-383 deg

Answers

Answer:

23º is not coterminal to 337º

Step-by-step explanation:

The coterminal angles ( $\theta$ ) of 337º can be represented as:

$\theta=337\º+360\ºn, n \in \mathbb{Z}$

If $n=1$

$\theta=337\º+360\º\n\theta=697$

If $n=-1$

$\theta=337\º-360\º\n\theta=-23$

If $n=-2$

$\theta=337\º-720\º\n\theta=-383$

Final answer:

The angle that is not coterminal with 337° is -383°. Coterminal angles differ by a multiple of 360°. The angles coterminal with 337° include -23°, 337°, and 697°.

Explanation:

In mathematics, two angles are said to be coterminal if they measure the same position when you start from the initial side and rotate to the terminal side. They differ by an integral multiple of 360°.

So, to find the angles that are coterminal with 337° we can add and subtract multiples of 360°. The options given are 23°, -23°, 697°, and -383°.

Adding and subtracting multiples of 360° from 337° gives us the following coterminal angles: -23°, 337°, 697°.

Therefore, the angle that is NOT coterminal to 337° is -383°

Raphael paid $167 for a camera during a 75% off sale. what was the cameras regular price?

Answers

As the camera was at 25% of the original price, this means you've got to multiply this number to by 4 to get the original price.
167*4= 668
Therefore, the camera's regular price is $668
Hope this helps :)

The original price of the camera was $292.25. I changed 75 percent to a decimal which became 0.75. Then I added $167 plus 0.75 which equals 292.25. When the dollar sign was added, $292.25 was the camera's original price.

Hope I helped! :)

log8 (x(x + 6)) = log8 (5x+12)

Please help me!

Answers

As log8(x(x+6)) = log8(5x+12) we can raise e by each side this getting x^2 + 6x = 5x + 12
x^2 + x - 12 = 0
(x+4)(x-3)=0
x=3, x=-4
However we can only do logs of positive number and when -4 is substituted into the equation it gives a negative number so the only true solution is x=3
