Please help with answering this problem.

Answer:

False; True; True.

Step-by-step explanation:

In this situation, the y-intercept would represent the amount of money in her account at x=0 weeks, or the beginning of the year.  This is not the x-intercept, so the first statement is false.

The slope is the rate of change.  This would describe how her account changes every week, so this represents the amount of money she deposits into her account each week.  This means the second statement is true.

The line goes through the point (4, 0).  Since x is the number of weeks, this would represent the amount in her account after 4 weeks.  Since the y-value is 0, this means she no longer has an overdraft balance after 4 weeks.  This means the second statement is true.

Following are the response to the given points:

Therefore, the final answer is "false, true, and true".

Answer:

The unit rate is 235 calories per hour.

Step-by-step explanation:

General house cleaning (sweeping the floor vacuuming laundry) can burn 470 calories every two hour determine the unit rate.

Unit rate means we have to find the calories burned in 1 hour.

Hence, calories burned in 1 hour = [tex]\frac{470}{2}= 235[/tex]

Answer :

The unit rate is 235 calories per hour.

Alex broke 3 glasses during the unpacking of the glasses.

As mentioned in the question, Alex was hired to unpack 576 items of glass wear, at five cents per piece unpacked. For every item broken in the process, however, Alex had to pay $1.98. At the end of the job, Alex received $22.71.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

The total amount earned for 576 glasses is given as,
= 576 × 0.05
= $28.80.

Amount earned = $22.71
Amount paid by Alex for the broken glass = $28.80 - $22.71 = 6.09
Total glass broked = 6.09 / 1.98 ≈ 3

Thus, Alex broke 3 glasses during the unpacking of the glasses.

Answer:

Answer when we  round off 446,221 to the nearest ten is 446,220

Step-by-step explanation:

We need to round off 446,221 to the nearest ten.

Nearest ten to the 446,221 can be 446,220 or 446,230

Difference between 446,221 and 446,220 = 446,221 - 446,220 = 1

Difference between 446,221 and 446,230 = 446,230 - 446,221 = 9

Here the difference is minimum for 446,220

Answer when we  round off 446,221 to the nearest ten is 446,220

Answer:

the answer is t = 20.625

Step-by-step explanation:

To begin, you would need to find the displacement of the first car and the equation to find that is d = 1/2at^2. So you would plug in what you have from the problem into the equation: d = (1/2)3(6)^2 and d is equal to 54 m. THIS IS YOUR DISPLACEMENT FOR THE FIRST CAR.

Next, you need to find the velocity of the car and the equation would be v = at. Plug in what you know from the problem: v = 3(6) which is 18. THIS IS YOUR INITIAL VELOCITY.

Next, we need to find out the distance of the 2nd car and we would use d = 1/2at^2. Plug in what you now from the problem: d = (1/2)5t^2 which would be d = 2.5t^2.

Next, you would equal these two equations together: 2.5t^2 = 1.5t^2 + 18t +54.  All these values are from when we solved them from above, and once you solve it you will get 20.625. (SOLVE FOR T)

Let the number of half dollars be x,

number of quarters = x + 2

amount of half dollars = 0.5x

amount of quarters = 0.25(x + 2)

= 0.25x + 0.5

total amount = 0.5x + 0.25x + 0.5

= 0.75x + 0.5

0.75x + 0.5 = 11.75

0.75x = 11.25

x = 15

number of quarters = x + 2

= 15 + 2

= 17

There are 17 quarters and 15 half dollars.

To calculate the balance after 6 years with compound interest, use the formula Balance = Principal * (1 + Interest Rate)^Time. Substituting the values, we find the balance to be approximately $2,243.89.

To calculate the balance after 6 years, we need to use the formula for compound interest:

Given that the principal (initial investment) is $1600 and the interest rate is 6.5%, we can substitute these values into the formula:

Calculating this, we find that the balance after 6 years is approximately $2,243.89.

The balance after 6 years is approximately $2105.69.

To find the balance after 6 years, we can use the formula for compound interest:

Balance = Principal(1 + Interest Rate)^Ti

Plugging in the given values, we have:

Balance = $1600(1 + 0.065)^6

Simplifying, we get:

Balance = $1600(1.065)^6

Calculating, we find that the balance after 6 years is approximately $oxed{2105.69}.

To express 645,300 in expanded form using exponents, it is written as [tex]6x10^{5} + 4x10^{4} + 5x10^{3}+ 3x10^{2}[/tex]x, breaking down each digit by its place value and expressing each as a power of 10.

To write the number 645,300 in expanded form using exponents, we break down each digit according to its place value and then express each of these as a power of 10. The place values for the number 645,300 are as follows:

The equation of the circle passing through the point (−5, −2) and center at (−2, 3) is  [tex]\bold{( x +2 )^2 + ( y - 3 )^2 = 34}[/tex]

The general equation of the circle whose center at (h, k) and radius r is,

[tex]( x - h )^2 + ( y - k )^2 = r^2[/tex]

For given example,

the circle passing through the point (−5, −2) whose center is at (−2, 3).

The radius of the circle is the distance between point (-5, -2) and the center (-2, 3).

Using distance formula the radius of a circle would be,

⇒ [tex]r=\sqrt{(-2-3)^2 + (-5-(-2))^2}[/tex]

⇒ [tex]r=\sqrt{(-5)^2+(-3)^2}[/tex]

⇒ [tex]r=\sqrt{25+9}[/tex]

⇒ [tex]r=\sqrt{34}[/tex] units

Let center (h, k) = (-2, 3)

Using the general form of the circle,

⇒ [tex]( x - h )^2 + ( y - k )^2 = r^2[/tex]

⇒ [tex]( x - (-2) )^2 + ( y - 3 )^2 = (\sqrt{34})^2[/tex]

⇒ [tex]( x +2 )^2 + ( y - 3 )^2 = 34[/tex]

Therefore, the equation of the circle passing through the point (−5, −2) whose center is at (−2,3) would be [tex]\bold{( x +2 )^2 + ( y - 3 )^2 = 34}[/tex]
