Vhich graph represents the function f(x) = x2 + 5?

For this case we have that by definition, the area of a circle is given by:

[tex]A = \pi * r ^ 2[/tex]

Where:

r: It is the radius of the circle

Circle 1:

[tex]A_ {1} = \pi * (10) ^ 2 = 100 \pi \ in ^ 2[/tex]

Circle 2:

[tex]A_ {2} = \pi * (6)^2 = 36 \pi \ in ^ 2[/tex]

Thus, the area of the region bounded is given by:

[tex]A = 100 \pi-36 \pi = 64 \pi \ in ^ 2[/tex]

Answer:

[tex]64 \pi \ in ^ 2[/tex]

Option B

Step-by-step explanation:

x^3 - 5x^2 - 4x + 20 (I'm assuming this is what you meant)

(1)^3 - 5(1)^2 - 4(1) + 20 = 1 - 5 - 4 + 20 = 12

(-1)^3 - 5(-1)^2 - 4(-1) + 20 = -1 - 5 + 4 + 20 = 18

(2)^3 - 5(2)^2 - 4(2) + 20 = 8 - 20 - 8 + 20 = 0

Now I know (x-2) is a factor of the polynomial.

Synthetic division

2 | 1. -5. -4. 20

| 2. -6. -20

-----------------------------

1. -3. -10. 0

x^2 -3x -10

Factor -> (x-5)(x+2)

So the factors of the original polynomial are (x-5), (x+2), and (x-2)

f(x) = 0 when x = -2,2,or 5

Answer:

Step-by-step explanation:

P(AUB)=P(A)+P(B)+P(A∧B),P(A∧B)=0 as both the events are independent.

P(AUB)=1/2+1/3=(3+2)/6=5/6

The probability value of P(A u B) is 2/3

The probability values are given as:

P(A) = 1/2

P(B) = 1/3

The required probability is then calculated using:

P(A u B) = P(A) + P(B) - P(A) * P(B)

This gives

P(A u B) = 1/2 + 1/3 - 1/2 * 1/3

Evaluate the product

P(A u B) = 1/2 + 1/3 - 1/6

Take the LCM

P(A u B) = (3 + 2 - 1)/6

Evaluate

P(A u B) = 2/3

Hence, the probability value of P(A u B) is 2/3

Answer:

Area is 491.07m to the nearest tenth

Step-by-step explanation:

Answer :

Toby: 4 of the $1.64, 1 of the $0.77, and 1 of the $3.59

Elisa: 3 of the $3.59

Heidi: 3 of the $3.59, and 1 of the $0.77

The question is a math problem about calculating the total cost of purchased fruits within a given budget. It requires us to determine the fruit combinations that match the total spending amount and the number of items bought for each individual.

The problem is a typical mathematics question focusing on money and budgeting. Toby, Elisa, and Heidi each have a budget between $10 and $12 to spend on fruit. Each fruit item's cost is given, and we need to assign a combination of fruits to each person that matches their total spending amount. Toby bought 6 items, Elisa bought 3, and Heidi bought 4.

For example, if Toby bought 6 bananas at 20 cents each, his total would be $1.20. As he needs to spend between $10 and $12, you would continue to mix and match the rest of the fruits until his purchase meets the criteria of total amount spent and number of items bought.

Step-by-step explanation:

see.... l is a perpendicular bisector of m.... so line l makes an angle 90° with m

so equation becomes

6(2x+1)= 90

12x + 6 = 90

12x = 90 - 6

12x = 84

x = 7

Thus the given expression is factored

Final answer:

The expression x²−12x+36 is factored as (x-6)(x-6) or (x-6)².

Explanation:

The expression x²−12x+36 represents a quadratic equation. To factor this expression, we look for two numbers that both add to the middle term, -12, and multiply to the constant term, 36. The numbers that fit this requirement are -6 and -6, since (-6) + (-6) = -12 and (-6) × (-6) = 36. Therefore, the expression in factored form is (x-6)(x-6), which can also be written as (x-6)².

Answer:

y = [tex]\frac{1}{3}[/tex] x + 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 1 ← is in slope- intercept form

with slope m = - 3

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-3}[/tex] = [tex]\frac{1}{3}[/tex], thus

y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation of the perpendicular line

To find c substitute (6, 3) into the partial equation

3 = 2 + c ⇒ c = 3 - 2 = 1

y = [tex]\frac{1}{3}[/tex] x + 1 ← equation of perpendicular line

The equation of the line that is perpendicular to y = -3x + 1 and passes through the point (6, 3) is y = 1/3x + 1

To find the equation of the line that is perpendicular to y = -3x + 1 and passes through the point (6, 3), we first need to find the slope of our new line. The slope of a line perpendicular to another is the negative reciprocal of the original slope. Since the slope of the original line is -3, the slope of the new, perpendicular line will be 1/3.

The general equation of a line is y = mx + b, where m is the slope and b is the y-intercept. We already have the slope, m = 1/3, and a point through which the line passes (6, 3). Substituting these values into the equation gives us 3 = 1/3 * 6 + b. Solving for b gives us b = 1.

Therefore, the equation of the line that is perpendicular to y = -3x + 1 and passes through the point (6, 3) is y = 1/3x + 1.

4.36 + 2.89 is equal 7.25 and 6.8 - 5.42 is equal 1.38

Step-by-step explanation:

4.36 + 2.89 = 7.25

6.8 - 5.42 = 1.38

Answer:

7.25

1.38

Step-by-step explanation:

a)  For first addition

4.36 + 2.89

Start adding from the right side. Take the last number and add them together.

9+6 = 15.................. write 5 and keep 1

Bring forward the kept "1"

3+8 + 1 = 12............. write 2 and keep 1

Bring forward the kept "1"

4+2 + 1 = 7...............write 7

∴ 7.25

b) For second subtraction

6.8 - 5.42 = 1.38

Start from the right side of each number

0 - 2 requires that you borrow "1" from "8" now turning "0" to "10" and "8" to "7".

now, 10 - 2 = 8...........write 8

         7 - 4 = 3.............write 3

         6 - 5 = 1..............write 1

∴ 1.38

Brady White lost 4 pounds in the first month, leaving him at 193 pounds. To reach his goal weight of 184 pounds, he needs to lose an additional 9 pounds.

(a) To find out how much weight Brady White lost in the first month, we subtract his weight at the end of the month from his initial weight.

Initial weight = 197 pounds

Weight at the end of the first month = 193 pounds

So, the weight lost = Initial weight - Weight at the end of the first month

= 197 pounds - 193 pounds

= 4 pounds

Therefore, Brady White lost 4 pounds in the first month.

(b) To determine how much more weight Brady needs to lose to reach his goal of 184 pounds, we need to find the difference between his current weight and his goal weight.

Current weight = 193 pounds

Goal weight = 184 pounds

So, the amount of weight Brady needs to lose = Current weight - Goal weight

= 193 pounds - 184 pounds

= 9 pounds

Therefore, Brady needs to lose 9 more pounds to reach his goal weight of 184 pounds.

Jasmine calculates the selling price of her jewelry by adding a markup percentage to the cost price. The sale price is equivalent to the cost price plus the percentage markup applied to this cost. For example, if the jewelry cost is $10 with a markup of 20%, the selling price will become $12.

Jasmine's method of pricing involves costs and percentage markup into consideration. To determine the selling price, she first calculates the cost to make the jewelry. This could include the cost of beads, thread, and her time. Afterwards, she determines the percentage markup. This is the additional amount on top of the cost price to generate profit. The equation can be written as: Selling price = Cost price + (Percent markup/100 * Cost Price).

For example, if it costs her $10 to make a piece of jewelry and she uses a markup of 20%, the amount of markup added would be $2 (20/100 x $10). Therefore, she would sell the jewelry for $12 ($10 + $2).

Step-by-step explanation: edge 2021

Answer:

For this, we can use the formula

A=P(1+rt).

We know that A=1,000, r=4%=0.04 and t=5, so we can rearrange the formula for P to give

P=A1+rt,

and substituting the known quantities gives

P=1,0001+(0.04)(5)=1,0001.2≈$833.33

to the nearest cent. So, to the nearest dollar she must deposit $833.

Step-by-step explanation:

Final answer:

Mary must deposit approximately $800 today into her account with a simple interest rate of 4% per year to have it worth $1,000 in 5 years.

Explanation:

To find out how much Mary must deposit today to have her account worth $1,000 in 5 years with a simple interest rate of 4% per year, we need to use the simple interest formula.

The formula for simple interest is I = P × r × t, where I is the interest, P is the principal amount (initial deposit), r is the annual interest rate (in decimal form), and t is the time in years.

The total amount A after t years is given by A = P + I. Since we know that A is $1,000, t is 5 years, and r is 0.04, we can rearrange the formula to solve for P:

In this case, the total interest earned in 5 years would be I = $1,000 - P. We can plug this into the interest formula: $1,000 - P = P × 0.04 × 5.

After simplifying, we'll find that P = $1,000 / (1 + 0.04 × 5), which calculates to P being approximately $800. So, Mary would need to deposit $800 today.

25x + 15y = 265

x+y = 13

Step-by-step explanation:

Step 1:

Given

Number of shirts Leah can iron in an hour = 25 shirts

Number of shirts Christopher can iron in an hour = 15 shirts

Total number of hours worked by both = 13 hours

Total number of shirts ironed by them = 265 shirts

Step 2 :

Let x represent the number of hours Leah works and y represent the number of hours Christopher works

Leah irons 25 shirts in one hour, so in x hours he would iron 25x shirts

Christopher irons 15 shirts in one hour, so in y hours he would iron 15y shirts

Given total shirts ironed by them together is 265 , we have

25x + 15y = 265

They worked a combined of 13 hours, so

x+y = 13

Step 3:

The system of equations that could be used to determine the number of hours Leah worked and the number of hours Christopher worked are ,

25x + 15y = 265

x+y = 13

Answer:

System of Equations:

x + y = 13

25x + 15y = 265

Answer:

16

Step-by-step explanation:

If it is compounded quarterly, that's 4 times a year.

If you do this for 4 years that's 4×4.

That would be 16.

We have been given invest $500 in an account that has a annual interest rate of 5%, compounded quarterly for four years. 16 times will the money be compounded.

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]

We have been given invest $500 in an account that has a annual interest rate of 5%, compounded quarterly for four years.

Since the interest is compounded quarterly so it will be compounded 4 times a year.

Now, 4 x 4 is 16, so it will be compounded 16 times.

Then we have to divide the 5% by four to get how much will be compounded each quarter.

So, (0.05 / 4) = 0.0125, which is 1.25%.
