It would be option 2. 20 miles per hour
(1/2(AC) * DC) / (1/2(BC) * DC) = 3/4
AC / BC = 3/4
The coordinate of C be (x, y), then
((4(1) + 3(8))/7, (4(-9) + 3(-2))/7) = ((4 + 24)/7, (-36 - 6)/7) = (28/7, -42/7) = (4, -6)
The answer is 5000 ft
His displacement is actually the hypotenuse (c) of the triangle with sides 6 blocks and 8 blocks.
According to the Pythagorean theoreme:
c² = a² + b²
c² = 6² + 8²
c² = 36 + 64
c² = 100
c = √100
c = 10 blocks
Since 1 block is 500ft long, then 10 blocks are 5000 ft long:
1 : 500ft = 10 : x
x = 10 * 500ft / 1 = 5000 ft
Answer:
It's nine plus negative three
Answer:
3
Step-by-step explanation:
To find the common ration, we take the 2nd term and divide it by the first term
15/5 = 3
Let check by taking the third term and dividing by the 2nd term
45/15 =3
The common ratio is 3
