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

$5 = t$

$t = 5\ seconds$

There is 3/4 of pizza leftover from the night before . how many 1/8 portions are there

serg [7]

We want to know how many 1/8's are in 3/4, so we divide.

$\sf\dfrac{3}{4}\div\dfrac{1}{8}$

Flip the 2nd fraction and multiply:

$\sf\dfrac{3}{4}\times\dfrac{8}{1}$

Multiply the numerators and denominators together:

$\sf\dfrac{3\times8}{4\times1}\rightarrow\dfrac{24}{4}$

Divide:

$\boxed{\sf6}$

I WILL GIVE YOU BRAINLIEST IF YOU ANSWER THE WHOLE QUESTION.

kicyunya [14]

Answer:

B) $y=2x$ and C) $y=-7x+9$

Step-by-step explanation:

Once a linear function has a constant rate of change, you just have to find the linear functions. Also, the other ones are quadratic functions, and their graph are parabolas, which don't have a constant rate of change.

Considering $f(x)=y$

$f(x) = 2x$ has a constant positive rate of slope 2.

$\frac{dy}{dx}=2$

$f(x)=-7x+9$ has a constant negative rate of slope -7

$\frac{dy}{dx}=-7$
