I need assistance with "What does the area of the rectangle depend on", the graph section, and the relationship section.
DanielleElmas [232]

The area equation here is:

A=2w^2

That means that the area depends on the width measurement of the rectangle.

To graph a quadratic function you have to see if the parabole is positive and the transformations, in this case, are positive and have a multiplication by two, which means that the graphics in x=1 and x=-1 will be y=2

Finally, you can conclude that there, you have a relationship between the area and the width of the rectangle because is a quadratic relationship and the area will increase in a quadratic form according to the increase of the width.

Please help. Approximately how many cubic feet of water does she need?
maria [59]

Answer:

The amount of water she needs to pump in:

V = Base area x Height x 1/2 = (4/2)^2 x pi x 0.75 x 1/2 = 1.5pi = ~4.7 (ft3)

Tpy6a [65]

Answer:

Extracting out that inner right angle.

Hypotenuse = 8

Height = h

Adjacent :

=  \frac{10}{5}  = 2

Height, h :

{ \tt{h =  \sqrt{ {8}^{2}  -  {5}^{2} } }} \\ { \tt{h =  \sqrt{64 - 25} }} \\ { \tt{h =  \sqrt{39} }} \\ the \: height \: is \: { \boxed{6.2}} \: units

1/2(n-5)=1/2(23-5) I cannot find what’s half of 23-5
liraira [26]

Answer:

n = 23

Step-by-step explanation:

if 1/2 (n-5) = 1/2 (23-5)

that must mean that n=23.

and if you are just looking for 1/2 of 23-5 that is just 9. (23-5) = 18 and half of 18 is 9

Jason owns a small business selling bagels. He knows that in the last week 45 customers paid cash, 8 customers used a debit card
tatuchka [14]

The probability that the next customer will pay with cash is 0.76

<h3>What is the probability?</h3>

Formula to find the probability of an event is:

P(A) = n(A)/n(S)

where;

n(A) is the number of favorable outcomes of an event A

n(S) is the total number of outcomes for an experiment/survey

We are given that;

45 customers paid cash

8 customers used a debit card

6 customers used a credit card.

Thus, the total number of customers:

n(S) = 45 + 8 + 6

n(S) = 59

Let event A be the event that the next customer will pay with cash. Thus, n(A) = 45

Therefore, the probability that the next customer will pay with cash would be;

P(A) = n(A)/n(S)

P(A) = 45/59

P(A) = 0.76
