Answer:

a. The expression is R = 5t

b. The area of the circle in terms of R is A = πR²

c. The area of the circle in terms of t is A = π(5t)²

d. The area of the circle in terms of t in the expanded form is A = 25π×t²

Linear systemIt is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

CircleIt is a locus of a point drawn at an equidistant from the center. The distance from the center to the circumference is called the radius of the circle.

Given

R = 5t where R is the radius, and t be the time.

Thus, the answer will be

a. The expression will be

R = 5t

b. The area of the circle in terms of R will be

Area = πR²

c. The area of the circle in terms of t will be

Area = πR²

Area = π(5t)²

d. The area of the circle in terms of t in the expanded form will be

Area = πR²

Area = π(5t)²

Area = 25π×t²

Answer:

Answer:

a. r = 5t

b.

c.

d.

Step-by-step explanation:

a. Since the radius is increasing at a constant rate of 5 cm per second.

r = 5t

where r is the radius at time t (seconds)

b. Area of circle

c. We can substitute r = 5t into the area formula to have

d. In expand form

Simplify square root of negative 121

No solution bc you can’t square a negative number and that’s on the quadratic equation sweetie

Answer:

No solutions

Step-by-step explanation:

A negative number can not be square rooted because it is impossible to get a negative square. When you square a negative number you would get a positive number, and when you square a positive number you would still get a positive number

Russell ate several candies on Halloween, and each day after Halloween ate 6 fewer candies than the day before. His candies lasted exactly five days, and he ate 100 candies in total. How many did he eat on the third day?

Let a = the number of candies eaten on the first day.

Because the number of candies eaten decreases by 6 every day after, the number of candies eaten creates the arithmetic sequence

a, a-6, a-12, a-18, ...,

After 5 days, the total candies eaten is 5a - 60.

Therefore

5a - 60 = 100

5a = 160

a = 32

On the third day, the number of candies eaten is

a - 12 = 32 - 12 = 20

Answer: 20

Because the number of candies eaten decreases by 6 every day after, the number of candies eaten creates the arithmetic sequence

a, a-6, a-12, a-18, ...,

After 5 days, the total candies eaten is 5a - 60.

Therefore

5a - 60 = 100

5a = 160

a = 32

On the third day, the number of candies eaten is

a - 12 = 32 - 12 = 20

What are the values of a, b, and c in the quadratic equation 0 = = x2 – 3x – 2?

a=1 h=30-2

Answer:

- a = 1
- b = -3
- c = -2

Step-by-step explanation:

The general form of a quadratic equation is often written as ...

ax² +bx +c = 0

The references to "a", "b", and "c" are to the coefficients in this form. Comparing this to your equation ...

x²-3x -2 = 0

we see that the coefficient of x², is 1, so a=1; the coefficient of x is -3, so b=-3, and the constant is -2, so c=-2.

Nick, you have $ 7.00. Bagels cost $ 0.75 each, and a small container of cream cheese costs $ 1.29. Write an inequality to find the numbers of bagels Nick can buy. Identify what your variable represents.

Let b= number of bagels you can buy and c = number of containers of cream cheese.

0.75b+1.29c

0.75b+1.29c

HIGH SCHOOL

Jakes has $20 to spend on notebooks and pencils the notebooks and pencils. the notebooks cost 3.25 and the pencils cost $.50 what is the maximum number of notebooks he can buy if he buys 8 pencil

Hey there. So basically, find out how much the pencils and notebooks cost first.

The notebooks cost = $3.25

The pencils cost = $0.50

Then, think about what you need to figure out in this problem.

Jake has $20. You need to find how many notebooks Jake can buy in maximum after buying 8 pencils.

If Jake buys 8 pencils that costs $0.50 each, he spends $4 on the pencils.

So now, to find out how many notebooks he can buy, do 20 minus 4.

Jake's got $16 left.

If the notebooks cost $3.25 each, we need to find out how many notebooks he can buy by dividing them. So, 16 divided by 3.25 equals 4.923... and so on.

That means, Jake can buy 4 notebooks with his remaining money.

The notebooks cost = $3.25

The pencils cost = $0.50

Then, think about what you need to figure out in this problem.
