Answer:

452.16 cm^2

Step-by-step explanation:

To find the area of a circle with the circumference we can say that half of the circumference is the radius. Hence our radius will be 12 cm.

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

A=[tex]\pi[/tex]12^2

A=[tex]\pi[/tex]144

A=144[tex]\pi[/tex]

We replace pi with 3.14

A=144*3.14

A=452.16

Answer:

Plug in those values for the x in the equations.

Step-by-step explanation:

f(x) = x^2 + x

   (x = -1) :: f(-1) = (-1)^2 + (-1)

                 f(-1) = -1 + -1

                 f(-1) = -2

   (x = 2) :: f(2) = (2)^2 + (2)

                 f(2) = 4 + 2

                 f(2) = 6

f(x) = x^2 - x

   (x = -1) :: f(-1) = (-1)^2 - (-1)

                 f(-1) = 1 - (-1)

                 f(-1) = 2

   (x = 2) :: f(2) = (2)^2 - (2)

                f(2) = 4 - 2

                f(2) = 2

f(x) = -x^2 - x

   (x = -1) :: f(-1) = -(-1)^2 - (-1)

                 f(-1) = -1 + 1

                 f(-1) = 0

   (x = 2) :: f(2) = -(2)^2 - (2)

                 f(2) = -4 - 2

                 f(2) = -6

Answer:

-35

Step-by-step explanation:

Using the rules of BIMDAS, division goes before addition, hence -20/2 which gives you -10

Put that in the equation and it would be:

-10 + (-15)

A negative and a positive make a negative hence, you could simply write it as:

-10 - 15

Which equals -35

Lets shift

[tex]\\ \rm\Rrightarrow f(x)=x^2[/tex]

[tex]\\ \rm\Rrightarrow g(x)=(x+2)^2[/tex]

[tex]\\ \rm\Rrightarrow g(x)=x^2+2x+4[/tex]

Answer:

g(x) = (x + 2)²

Step-by-step explanation:

In function notation, if we want to shift a function to the left, we add the number we are asked to move to the left inside the function's argument:

⇒ To shift f(x) b units to left → f(x + b)

Similarly, if we want to shift a function to the right, we subtract the number we are asked to move to the right inside the function's argument:

⇒ To shift f(x) b units to right → f(x - b)

Given function f(x) = x²

Shift 2 units to the left:  f(x + 2) = (x + 2)²

Therefore, g(x) = (x + 2)²

Answer:

y=(x-5)^2

Step-by-step explanation:

Y= (x-5)^2

Y= 1/3x +8

Y - 4 = 2(x-1)

9x - 2y = -18

This equation is exponential so it won't have a straight slope.

[tex] \sqrt{75} + \sqrt{108} = a \sqrt{b} [/tex]

[tex] \sqrt{75} = \sqrt{3 \times 5 {}^{2} } = 5 \sqrt{3} [/tex]

[tex] \sqrt{108} = \sqrt{2 {}^{2} + 3 {}^{3} } = 2 \times 3 \sqrt{3} = 6 \sqrt{3} [/tex]

[tex] \sqrt{75} + \sqrt{108} = 5\sqrt{3} + 6 \sqrt{3} = 11 \sqrt{3} [/tex]

[tex]a = 11[/tex]

Answer:

21 students earn the reward

Step-by-step explanation:

15% is equivalent to the fraction 3/20 so, you must divide 140 by 20 then multiply by 3 to get the final answer of 21 students.

15% = 3/20
140 divided by 20 = 70
70 x 3 = 210
210 divided by 10 = 21

In conclusion, your answer would be that 21 students get the Presidential Physical Fitness Award.

Step-by-step explanation:

The length of the arc subtending a central angle of 9π/5 radians is 152.12m.

The radius of the given circle r = 26.9m

The measure of the central angle α = [tex]\frac{9\pi }{5}[/tex] radians

The arc of a circle is defined as the part or segment of the circumference of a circle. Its length is the product of the central angle(in radian) and radius of the circle.

So, the length of the arc subtending a central angle of 9π/5 radians

l = rα

l = 26.9 * 9π/5

l = 152.12m

Therefore, the length of the arc subtending a central angle of 9π/5 radians is 152.12m.

Answer:

The correct option is A....

Step-by-step explanation:

We have a table of x,y pairs. To compute the slope we can use any two pairs, say the first two, and plug them into our formula:

m = y2-y1 / x2-x1

m = 5-13/ 0-(-2)

m = -8/0+2

m = -8/2

m = -4

We can check this answer by using a different pair: Take the last two pairs.

m = -27-(-15)/ 8-5

m = -27+15/3

m = -12/3

m = -4

Thus the slope is -4

Using the area of a rectangle, it is found that her patio should have a width of 12 feet and a length of 27 feet.

The area of a rectangle of length l and width w is given by:

A = lw.

In this problem:

Thus:

324 = w(15 + w)

w^2 + 15w - 324 = 0

w = -27 or w = 12.

We take the positive value, hence l = 15 + w = 15 + 12 = 27 feet.

The dimensions should be a width of 12 feet and a length of 27 feet.

Answer:

Greatest common factor (GCF) of 60 and 64 is 4.

Step-by-step explanation:

The HCF of two numbers 60 and 64 is 4.

LCM is the least common multiple is the smallest number that is divisible by two or more than two given numbers.

We know that the greatest common factor of two or more than two numbers is the largest number that divides the given numbers completely.

Given we have to find HCF of 60 and 64.

2 can divide both the numbers but 4 also divides the numbers and n such no. more than 4 divide them completely and simultaneously.

∴ HCF of 60 and 64 is 4.

The balance in his account at the end of 4 years will be $289.67.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Principal amount (P) = $250

Rate (r) = 3.75%

Time (t) = 4 years

Now,

Since, We know that;

⇒ [tex]A = P (1 + \frac{r}{100} )^t[/tex]

Where, A is the future amount.

P is the principal amount.

t is the time.

r is the rate.

Thus, By substitute all the values, we get;

⇒ [tex]A = P (1 + \frac{r}{100} )^t[/tex]

⇒ A = 250 (1 + 3.75/100)⁴

⇒ A = 250 (103.75/100)⁴

⇒ A = $289.67

Thus, The balance in his account at the end of 4 years will be $289.67.
