Suppose a car going 65 mph is traveling north parallel to a train going 50 mph. Once the front of the car is as far north as the

scoray [572]

Answer:

0.75 Miles

Step-by-step explanation:

To find the answer we have to find the difference in the distance the train and car travelled

65/60 is 1.083333 which is miles per minute then multiplied by 3 is 3.25 mile gone in 3 minutes

For the train it is 50/60 which is 0.833333 and the times 3 is 2.5 miles in three minutes

3.25 miles minus 2.5 miles is 0.75 miles so that is how long the train is

Multiply: k+3 4k−2 ×(12 k 2 +2k − 4)

Dmitriy789 [7]

K+3 * 4k=12k
2(12k * 2 + 2k - 4) = 2(26k - 4)
= k + 12k - 2 (26k - 4)
- 2 (26k - 4) : -52k+8
=k + 12k - 52k = -39k
FINAL ANSWER = -39k + 8

What is the length of leg y of the right triangle?

xz_007 [3.2K]

Answer:

13

Step-by-step explanation:

We need to use the Pythagorean Theorem to solve this problem:

$a^{2} +b^{2} = c^{2}$ , where a and b are the legs of the right triangle and c is the hypotenuse

In this case, we already know b (b = 84) and c (c = 85), so we need to solve for a:

$a^{2} = c^{2} - b^{2} = 85^{2} - 84^{2} = 169 = 13^{2}$

Thus, a = y = 13.

Answer:

So the answer is A

Step-by-step explanation:

A)

$f(x)=815.03(1.38)^{x}$

f(1) = 1124.74

f(2)= 1552.143

f(3) = 2141.9575

f(4)= 2955.901

f(5)= 4079.1439

So the answer is A

B)

$f(x)=1.38x^{2} -2.64x+815.03$

f(1) = 813.77

wrong!

C)

$f(x)= 1.38x+815.03$

f(1) = 816.14

D)

$f(x)=815.03\sqrt{x} -1.38$

f(1)= 813.65

wrong!
