ANSWER

The area of the shaded sector is

[tex]Area =\pi \: {in}^{2} [/tex]

EXPLANATION

The area of a sector is calculated using the formula,

[tex]Area = \frac{central \: angle}{360 \degree} \: \times \pi \: {r}^{2} [/tex]

Fro the diagram, the central angle is 90°

The radius of the circle is 2 in.

[tex]Area = \frac{90 \degree}{360 \degree} \: \times \pi \: {2}^{2} {in}^{2} [/tex]

[tex]Area = \frac{1}{4} \: \times \pi \: 4 {in}^{2} [/tex]

This finally simplifies to

[tex]Area =\pi \: {in}^{2} [/tex]

Answer:

Area of shaded region = 3.14  in²

Step-by-step explanation:

Formula:-

Area of circle = πr²

Where 'r' is the radius of circle

It is given a circle with radius 2 in.

To find the area of circle

Here r = 2 in

Area = πr²  = 3.14 * 2² = 12.56 in²

To find the area of shaded region

Here central angle of sector = 90°

area of sector= (90/360) * area of circle

 = (1/4)12.56 = 3.14  in²

The Remainder Theorem states that when we divide a polynomial f(x)

by x − a the remainder R equals f(a).

a = -2

Syntetic substitution.

1. Write only the coefficients of x in the dividend inside an upside-down division symbol.

[tex]\underline{\begin{array}{c|ccccccc}\ &1&-3&0&5&0\\\ \end{array}}[/tex]

2. Put the divisor at the left.

[tex]\underline{\begin{array}{c|ccccccc}-2&1&-3&0&5&0\\\ \end{array}}[/tex]

3. Drop the first coefficient of the dividend below the division symbol.

[tex]\underline{\begin{array}{c|ccccccc}-2&1&-3&0&5&0\\\ \end{array}}\\\begin{array}{ccccccccc}\ \ \ \ &1\end{array}[/tex]

4. Multiply the drop-down by the divisor, and put the result in the next column.

[tex]\underline{\begin{array}{c|ccccccc}-2&1&-3&0&5&0\\\ &&-2\end{array}}\\\begin{array}{ccccccccc}\ \ \ \ &1\end{array}[/tex]

5. Add down the column.

[tex]\underline{\begin{array}{c|ccccccc}-2&1&-3&0&5&0\\\ &&-2\end{array}}\\\begin{array}{ccccccccc}\ \ \ \ &1&-5\end{array}[/tex]

6. Repeat 4 and 5 until you can go no farther

[tex]\underline{\begin{array}{c|ccccccc}-2&1&-3&0&5&0\\\ &&-2&10&-20&30\end{array}}\\\begin{array}{ccccccccc}\ \ \ \ &1&-5&10&-15&30\end{array}[/tex]

The remainder is 30, so f(-2) = 30.

Check:

Answer:

Yes, she has enough paint, since she does not need to paint the window. The area that needs to be painted is only 87 ft², and she has enough paint for 90 ft².

Step-by-step explanation:

Area of the wall (including window)

= 12 x 8

= 96 ft²

Area of the window

= 3 x 3

= 9 ft²

Area of the wall that needs to be covered with paint

= 96 - 9

= 87 ft²

Answer:

Yes, she has enough paint. The area to be painted is the area of the wall minus the area of the window. A = (12)(8) = 96; A = (3)(3) = 9; area to be painted: 96 – 9 = 87 square feet.

Answer:

Step-by-step explanation:

Moving from (0, 4) to (2, 3), we see x increasing by 2 from 0 to 2 and y decreasing by 1 from 4 to 3.

Thus, the slope of this line is m = rise / run = -1/2.

Starting with y = mx + b, we substitute 0 for x, 4 for y and -1/2 for b, obtaining:

4 = (-1/2)(0) + b.  Therefore, b = 4, and the desired equation is:

y = (-1/2)x + 4

Step-by-step explanation:

The ratio received = 9 : 13 : 18

Sum the parts of the ratio 9 + 13 + 18 = 40

Divide the amount by 40 to find the value of one part of the ratio

[tex]\frac{800}{40}[/tex] = £20 ← value of 1 part of ratio

Eli gets 9 × £20 = £180

Freda gets 13 × £20 = £260

Geoff gets 18 × £20 = £360

To divide £800 between Eli, Freda and Geoff based on their ages, we need to find the ratio of their ages and divide the total amount by this ratio. Eli will get £180, Freda will get £260, and Geoff will get £360.

To find out how much each person will get, we need to divide the total amount of money by the sum of their ages in the given ratio.

The sum of their ages is 9 + 13 + 18 = 40.

The ratio is 9:13:18.

Answer:

Step-by-step explanation:

The measure of angle H from the given figure is 67.5 degree.

Vertical angles theorem or vertically opposite angles theorem states that two opposite vertical angles formed when two lines intersect each other are always equal (congruent) to each other.

Given that measure of angle F is 67.5°

The angles formed when two lines cross each other are known as vertical angles. Vertically opposite angles are the opposing angles created by these lines.

In simple words, vertical angles are located across from one another in the corners of the "X" formed by two straight lines.

From the given figure,

∠F=∠H (Vertically opposite angles are equal)

Angle F= Angle H=67.5°

So, angle H is 67.5 degree

Therefore, the measure of angle H is 67.5 degree.

Answer:

A, B and D.

Step-by-step explanation:

A:  because 5* 5^(x-1) = 5^(x - 1 + 1) = 5^x.

B. 15^x / 3 = 5^x

D. (15/3)^x = 5^x.

( Note C = 5 , E = 5^(x+2) and x^5 not = 5^x.)

Final answer:

The equivalent expressions to 5^x are 5*5^(x-1), 15^x/3^x, and (15/3)^x. These follow the rules of adding exponents when multiplying with the same base and raising an entire factor to a power.

Explanation:

The student has asked which expression is equivalent to 5x. To find expressions equivalent to exponents, we use rules such as the product of powers, which states that when multiplying expressions that have the same base, we can add their exponents (e.g., 5a  imes 5b = 5a+b). Similarly, to raise an exponential factor to a power, we multiply the exponent by the power.

The probability of selecting a boat from Rhode Island is 7 out of 14, which simplifies to 1/2, or 50%. There's an equal chance of picking a boat from Rhode Island as not.

The probability of selecting a boat from Rhode Island at the marina is calculated by dividing the number of Rhode Island boats by the total number of boats.

There are 7 boats from Rhode Island and 14 boats in total.

Therefore, the probability is 7 out of 14, which simplifies to 1/2 when reduced.

This can also be written as a decimal, 0.5, or a percentage, 50%, indicating that there is an equal chance of selecting a Rhode Island boat as there is of selecting a boat from another place.

Thus, there's an equal chance of picking a boat from Rhode Island as not.

Final answer:

The probability that a randomly selected boat will be from Rhode Island is 1/2.

Explanation:

To calculate the probability that a randomly selected boat at the marina is from Rhode Island, we use the basic probability formula:

Probability (P) of an event = (Number of favorable outcomes) / (Total number of possible outcomes)

Given that there are 7 boats from Rhode Island and a total of 14 boats at the marina, the probability (P) that a randomly selected boat is from Rhode Island is:

P(Rhode Island) = 7 / 14 = 1/2.

Therefore, the simplified fraction representing the probability is 1/2.

Answer:

Formula

r = d/2

r = 10/2

r = 5

SA = 2*pi*r^2 + pi*d*h

Solution

SA = 2 * pi * 5^2 + pi * 10 * 20

SA = 2 * 25 *pi  + pi * 200

SA = 50 pi + 200 pi

SA = 250*pi

Step-by-step explanation:

1 pound of carrot and 1.5 pounds of squash cost $7.00.

1c + 1.5s = 7 ----------------- [ 1 ]

4.5 pounds of carrot and 1.75 pound of squash cost $14.00.

4.5c + 1.75s = 14 ----------------- [ 2 ]

[ 1 ] x 4.5:

4.5c + 6.75s = 31.5 ----------------- [ 1a ]

[1a] - [2]:

5s = 17.5

s = $3.50

Sub s = 3.5 into [ 1 ]:

1c + 1.5 (3.5)  = 7

1c + 5.25 = 7

1c = $1.75

By setting up and solving a system of linear equations based on the purchases made by two customers, we calculated the price of carrots to be $2.00 per pound.

To determine the price per pound for carrots, we can set up a system of linear equations based on the provided information and solve it. Let 'c' represent the cost per pound of carrots and 's' represent the cost per pound of squash.

Multiplying Equation 1 by 3 gives us:

Now, let's subtract Equation 2 from this new equation to eliminate 's' and solve for 'c'.

After calculating, we find that c = $2.00 per pound for carrots.

   Parabola defined by the equation y = -x² - 3x + 6 will be represented by the picture attached.

Equation of the parabola given in the question is,

y = -x² - 3x + 6

Convert this equation in the vertex form, [y = a(x - h)² + k, here (h, k) is the vertex of the parabola]

y = -x² - 2(1.5)x - (1.5)² + (1.5)² + 6

  = -(x + 1.5)²+ (1.5)² + 6

  = -(x + 1.5)² + 2.25 + 6

  = -(x + 1.5)² + 8.25

From this equation vertex of the parabola will be (-1.5, 8.25).

Leading coefficient 'a' = -1 (negative)

y - intercept of the equation → y = -(0 - 1.5)² + 8.25

                                                  y = 6

x- intercept of the equation → 0 = -(x - 1.5)² + 8.25

                                                 (x - 1.5) = √8.25

                                                 x = 1.372, -4.372

  Therefore, parabola will open downwards (a is negative), y-intercept (0, 6) and x-intercepts as (-4.372, 0), (1.372, 0) and vertex as (1.5, 8.25).
