Answer:

  904.8 cm²

Step-by-step explanation:

The formula for the area of a circle is ...

  A = πr²

The area of a circle with radius 24 cm is ...

  A = π(24 cm)² = 576π cm²

A semicircle is half a circle, so its area will be ...

  (1/2)(576π cm²) = 288π cm² ≈ 904.8 cm² . . . area of the semicircle

He has given away 6/8 of his fraction.

Step-by-step explanation:

2/8 to sister + 4/8 to friend=6/8 just want to say would you give more of a fraction of your coins to your friend or sister?

any way 4+2=6 and 6/8 is the fraction he gave away so he has 2/8 left

Answer:

m = [tex]\frac{5}{4}[/tex]

Step-by-step explanation:

To find the slope, we have to use the slope formula:

m = [tex]\frac{y_2 -y_1}{x_2 - x_1}[/tex].

Let [tex](x_1,y_1) = (7, -2)[/tex] and [tex](x_2,y_2) = (3, -7)[/tex]. Then

m = [tex]\frac{(-7)-(-2)}{3-7} = \frac{-5}{-4} = \frac{5}{4}[/tex]

Answer:

  3/4 = 9/12

  5/3 = 20/12

Step-by-step explanation:

You can find the numerator of the fraction by multiplying the fraction by 12. Equivalently, find the factor the denominator must be multiplied by to make 12. Multiply the numerator by that same factor.

  3/4 = (3/4)(3/3) = (3∙3)/(4∙3) = 9/12

  5/3 = (5/3)(4/4) = (5∙4)/(3∙4) = 20/12

I don't really know but I would say number 2 is true

Answer:

1. -2 , 10        2. False       3.  13

Step-by-step explanation:

1. if we move 4 steps of -6, it can negative and also positive.

so fr positive: -6 + 4 = -2 , for negative: -6 - 4 = 10

2. False, they are at different distance.

3. successor of 6 is 7 and adding them 6 + 7 = 13.

Answer:D

u have 4 already and multiply the 3.5 by how many hours they choose to skate so h times 3.5 is 3.5h+ 4

which is the original rental price

Step-by-step explanation:

Option D is correct as it's most approximately close

​The approximate solution of the provided equation after three iterations of successive approximations is when x is about is -37/16.

The Iteration method is the process which takes the initial value to produce the series of successive approximations of the solution of the equation.

The equation given in the problem is,

[tex]\dfrac{2}{x+4}= 3^x + 1[/tex]

Solve it further,

[tex]-3^x -1+\dfrac{2}{x+4}= 0[/tex]

Let the above function if f(x),

[tex]f(x)=-3^x - 1+\dfrac{2}{x+4}[/tex]

The differentiations of the above function is,

[tex]f'(x)=-3^x \ln3-\dfrac{2}{(x+4)^2}[/tex]

Here, for this function

x             0,           -1,                -2,          -3    

x          -1.5,       -0.667,        -0.111,       0.963    

Here, the function,

[tex]f(-3)=0.963 > 0 \;\;\;\text{and}\\f(-2)=-0.111 < 0[/tex]

Hence, the roots lies between -3 and -2.

[tex]x_o=\dfrac{-3+-2}{2}\\x_o=-2.5[/tex]

This value is more near to the value -37/16 from the given option.

Thus, the approximate solution of provided equation after three iterations of successive approximations is when x is about is -37/16.

The dog eats 6 cupcakes in 22 days.

(don't know why a dog would be eating cupcakes in the first place, but sometimes math questions don't make the most sense)

Answer:

6 cupcakes

Step-by-step explanation:

"Every 11 days, my dog eats 3 cupcakes" can be written as a proportional relationship in fraction form: [tex]\frac{11}{3}[/tex].

Now, let's set a proportion between the values given.

As you can see, the number of days is multiplied by 2 to get 22 days. Whatever we do to the numerator, we must do to the denominator. Then, 3 multiplied by 2 is 6.

Therefore, the answer is 6 cupcakes.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Step-by-step explanation:

you have 18 choices for the birthday cards.

for each of these 18 choices you have 6 choices to get well cards. that means there are 18×6 choices just for these 2 card types alone.

for each of these 18×6 choices you have then 9 choices of graduation cards. that is in total 18×6×9 choices.

for each of these 18×6×9 choices you have then 12 choices of anniversary cards. that is in total

18×6×9×12 choices = 11,664 choices or ways the cards can be selected.

Answer:

141

Step-by-step explanation:

The given polynomial to us is ,

[tex]\implies f(x) = 4x^5 + 3x^2 + 1 [/tex]

And we need to find out the remainder when it is divided by ,

[tex]\implies g(x) = x - 2 [/tex]

Using the Remainder Theorem , firstly equate [tex] g(x) [/tex] with zero . So that ,

[tex]\implies x - 2 = 0 [/tex]

Add 2 on both sides ,

[tex]\implies x = 2 [/tex]

Therefore here the remainder will be [tex]f(2)[/tex].Now substitute x = 2 in f(x) .

[tex]\implies f(2) = 4(2)^5 + 3(2)^2 + 1 [/tex]

Simplify the exponents ,

[tex]\implies f(2) = 4 (32) + 3(4) + 1[/tex]

Solve the brackets ,

[tex]\implies f(2) = 128 + 12 +1 [/tex]

Add the terms ,

[tex]\implies \boxed{\quad f(2) = 141 \quad} [/tex]

Hence the remainder is 141 when f(x) is divided by (x-2) .

Answer:

12

Step-by-step explanation:

90 divided by 8 = 11.25, so you need 12 vans

to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".

[tex]\stackrel{f(x)}{y}=\cfrac{1}{x^2}\implies \stackrel{\textit{quick switcheroo}}{x=\cfrac{1}{y^2}}\implies y^2=\cfrac{1}{x}\implies y=\sqrt{\cfrac{1}{x}}\implies \stackrel{f^{-1}(x)}{y}=\cfrac{1}{\sqrt{x}}[/tex]
