Lena [83]

Mia walked 7km/h so after 1 hour, she is 7 km north of the house of Julia

Samantha walked 11km/h so after 1 hour, she is 11 km west of the house of Julia.

The points where Mia and Samantha are after 1 hour , and the house of Julia form a right triangle with sides 7 and 11 km. The distance between the girls, is the hypotenuse of his triangle.

by the pythagorean theorem:

$MS= \sqrt{ 7^{2} + 11^{2} }= \sqrt{49+121}= \sqrt{170}= 13 (km)$

Answer: 13 km

1. ESSENTIAL QUESTION How can you

olasank [31]

Answer:

If the increases are roughly the same, then linear is best. If the multiple factor is roughly the same, then an exponential is best. If the rate at which the increase increases is roughly the same (so A-B=1, B-C=3 C-D=5.2), then quadratic is best.

Which expressions are equivalent to the one below? Check all that apply. log2 16 + log2 16 A. log2(28) B. 8 C. log 256 D. log2 2

eduard

Answer:

B. 8.

D. log2 256.

Step-by-step explanation:

Generally:

loga b + loga b

= loga b^2.

Therefore log2 16 + log2 16

= log2 16^2

= log2 256.

From the above:

256 = 2^x where x is the log.

Now 2^8 = 256 so the original log2 16 + log2 16 = 8.
