A.

80,846

B.

68,486

C.

88,604

D.

64,808

D I’m pretty sure because 8 times itself = 64

**Answer:**

i think its D

**Step-by-step explanation:**

i think its D

**Answer: The value of y is 8**

**Step-by-step explanation:**

Since we know x=2 we can sub in 2 for x in the equation

y=2(2)+4

y=4+4

y=8

x/2 is the same thing as 1/2x

**Answer:**

week 3

**Step-by-step explanation:**

week 3 is correct, because both of their teams have 3 wins for week 3 as stated on Bailey's table and plotted on Jade's graph.

that is height

h=16t^2+16t+480

when h=0 is when it hits the water

0=16t^2+16t+480

undistribbute 16 for ease

0=16(t^2+t+30)

16*0=0 so assume

t^2+t+30=0

factor

(t+6)(t-5)=0

set to zero

t+6=0

minus 6

t=-6

false, since you cannot have negative time

t-5=0

add 5

t=5

at t=5 she hits the water

5 seconds

h=16t^2+16t+480

when h=0 is when it hits the water

0=16t^2+16t+480

undistribbute 16 for ease

0=16(t^2+t+30)

16*0=0 so assume

t^2+t+30=0

factor

(t+6)(t-5)=0

set to zero

t+6=0

minus 6

t=-6

false, since you cannot have negative time

t-5=0

add 5

t=5

Find a formula for y in terms of x

**Answer:**

**Step-by-step explanation:**

y being *directly proportional* to the square of x means that the ratio between the two will always be equal to some constant (let's call it **k**). In equation form, we'd say:

We're told that y = 96 when x = 4, so we can plug those values in to find k:

Our more general equation is now

If we want to put y in terms of x, we need to get the y by itself on one side of the equation, which we can do here by multiplying both sides by x², giving us

The question is about finding the equation given that y is directly **proportional **to the square of x. Based on the values in the question, the constant of proportionality 'k' is calculated as 6. Hence, the formula for y in terms of x is y = 6 * x^2.

When we say, *y* is directly proportional to the square of *x*, it simply means there is a constant **constant of proportionality 'k'**, such that *y = k * x**2*. Given in the problem, when *x* = 4, *y* = 96, we can substitute these values into the equation to solve for 'k'. This results in 96 = k * (42) which simplifies to 96 = 16k, and solving this gives us **k = 6**. Therefore, the formula for y in terms of x is **y = 6 * x****2**.
