Hi there! :)

Answer:

\huge\boxed{\frac{17}{7} }

Given ratio of 51 boys to 21 girls:

Write as a ratio:

51 : 21

Divide both terms by GCF, or 3:

\frac{51}{3} : \frac{21}{3}

17 : 7 or \frac{17}{7}

Therefore, the ratio is 17 boys to 7 girls, or   \boxed {\frac{17}{7}}

A fish swims over the waterfall. The distance y (in feet) that the fish falls is given by the function y=16t2 , where t is the t
inessss [21]

Answer:

See Explanation

Step-by-step explanation:

Given

y = 16t^2

The equation is incomplete. However, a possible question could be to calculate the distance of the fish at a particular time

e.g. Time, t = 4,

The distance is:

y = 16t^2

y = 16 * 4^2

y = 16 * 16

y = 256ft

Another possible question is to determine the time taken to cover a certain distance

e.g.

Distance, y = 400

This gives:

y = 16t^2

400 = 16t^2

Divide by 16

25 = t^2

Take square roots

5 = t

t = 5\ seconds

I need answers for 1 and 2
Snowcat [4.5K]

1. Slope 3/4, through (4,-1)

y = 3/4 x + b

-1 = 3/4(4) + b

-1 = 3 + b

-1 - 3 = b

-4 = b

y = 3/4 x - 4

2. Slope = - 1/2, through (3,0)

y = -1/2 x + b

0 = -1/2(3) + b

0 = -1.5 + b

0 + 1.5 = b

1.5 = b

y = -1/2 x + 1.5
