REPOST!!!!!! 20 POINTS!!!!!!

Mathematics
1 answer:
kkurt [141]2 years ago
6 0

Answer:

A

Step-by-step explanation:

according to tangent property

we get

  • AM=BM
  • AN=CN
  • BK=CK

Given that

  • AM=6
  • BK=4

Thus our equation is

\rm \displaystyle 2AM + 2AN + 2BK = 34

substitute the given values

\rm \displaystyle 2.6+ 2AN+ 2.4 = 34

simplify multiplication:

\rm \displaystyle 12+ 2AN+ 8 = 34

simplify addition:

\rm \displaystyle 2AN+ 20= 34

cancel 20 from both sides:

\rm \displaystyle 2AN=14

divide both sides by 2:

\rm \displaystyle AN=7

AN=CN

hence,CN=7

therefore our answer is A

Problem 1

Answer: C) No solution

---------------------------

Explanation:

We have z = -4 and 4z = -4 at the same time. Solving 4z = -4 leads to z = -1

So in effect we have z = -4 and z = -1 at the same time, but this is a contradiction. A variable can only hold one number at a time.

======================================================

Problem 2

Answer: C) Infinitely many solutions

---------------------------

Explanation:

The two equations are equivalent. You can prove as such by isolating 2y in the first equation.

5x = 8-2y

5x+2y = 8

2y = 8-5x

2y = -5x+8

-5x+8 = 2y

This shows the first equation is equivalent to the second, and vice versa. They both graph the same line. Any point along the line is a solution. So that's why there are infinitely many of them.

======================================================

Problem 3

Answer: Choice A) -6 < y \le 3

---------------------------

Explanation:

The range is the set of the possible y values. We're concerned with every y coordinate of each (x,y) solution. So we only focus on the shaded region.

The dashed line means we exclude the boundary. It's an electric fence we cannot touch. So y > -6 or -6 < y describes part of the range

The other part is y \le 3 since y = 3 is the when the highest point occurs.

So writing -6 < y \le 3 describes all possible y values of each (x,y) solution in the shaded region.

The tires on your bicycle have a diameter of 9 inches. How many rotations does each tire make when you travel 300 feet? Round yo
kherson [118]
So we know that the tire is 9 inches and its traveling 300 feet so 
1 foot = 12 inches
300 feet x 12 = 3600 inches
3600 inches divided by 9 = 400 rotations
