Change divide sign to multiplication sign, and flip second fraction
= 41/21 × 23/8

multiply top numbers together and multiply bottom numbers together
= (42×23)/(21×8)
=943/168

You can do the multiplicative inverse by mutiplying 41/21 and 8/23. But, you have to switch the second number to 23/8. Once it's switched, you just multiples straight across. So, it is 943/168. Just simplify it

An arch is in the shape of a parabola. It has a span of 100 feet and a maximum height of 25 ft.

Answer:

$y=-\frac{1}{100}(x-50)^2+25$

the height of the arch 10 feet from the center is 24 feet

Step-by-step explanation:

An arch is in the shape of a parabola. It has a span of 100 feet, the vertex lies at the center 50 and the maximum height of 25 ft.

Vertex at (50,25)

vertex form of the equation is

$y=a(x-h)^2+k$ , (h,k) is the center

$y=a(x-50)^2+25$

the parabola starts at (0,0) that is (x,y)

$0=a(0-50)^2+25$

subtract 25 from both sides

$-25=a(-50)^2$

$-25=a(2500)$

divide both sides by 2500

$a=-\frac{1}{100}$

$y=-\frac{1}{100}(x-50)^2+25$

the height of the arch 10 feet from the center.

center is at 50, 10 feet from the center so x=40 and x=60

$y=-\frac{1}{100}(40-50)^2+25$

y=24

the height of the arch 10 feet from the center is 24 feet

A fish with 68 meters at a constant speed in 8 minutes. On her homework assignment, Tracy said the fish traveled 60 meters per m

Natasha2012 [34]

Morgan is right because to find how much something is per minute you need to divide. In this case, you need to divide 68 and 8. The answer then is 8.5
