Answer:

13) cos D = 0.4706

14) cos G = 0.28

15) cos M = 0.6667

Step-by-step explanation:

13) Cos D = 8/17 = 0.4706

14) GI² = 7² + 24²

GI² = 49 + 576 = 625

GI = 25

cos G = 7/25 = 0.28

15) MN² = 3²- (√5)²

MN² = 9 - 5 = 4

MN = 2

cos M = 2/3 = 0.6667

Hundred tens one

The question is asking for to round to the nearest hundred (100) which means is rounding to [9] in this question.

The number of the place before the hundreds place is [8] on the tens place.

  • When numbers are greater than or equal to 5, you round up a digit.
  • When numbers are less than 5, you round down a digit.

[8] is greater than 5, so you round 9 up. When rounding 9 up, you get 10.

What is the Slope and y intercept
Inessa [10]

Answer:

The slope is .075 and the y intercept is -.125

Step-by-step explanation:

8y = .2(3x -5)

Distribute the .2

8y = .6x - 1

Divide by 8

8y/8 = .6x/8 -1/8

y = .075x -.125

This is in slope intercept form  y= mx+b  where m is the slope and b is the y intercept.

The slope is .075 and the y intercept is -.125
