On what intervals are the function's values positive?
10.
What are the zeros of the function?

Answer: [tex]V = 24,416.64m^{3}[/tex]

Step-by-step explanation:

Solve for v  by simplifying both sides of the equation, then isolating the variable.

Formula: [tex]v = \frac{4}{3} \pi r^{3}[/tex]

Plugin the variable: [tex]v = \frac{3}{4}\pi (18^{3})[/tex]

Solve:

[tex]v = \frac{4}{3} 3.14 (5,832)[/tex]

[tex]v = 4.18666666(5,832)[/tex]

[tex]V = 24,416.64m^{3}[/tex]

Answer:

​7.14*10^-4rand

Step-by-step explanation:

If the cost of cereal is 35rand for 1 kg, this can be expressed as;

35 and = 1kg

To get the cost of 25grams, we can write

25g = x

0.025 kg  = x

Divide both expressions

35/0.025 = 1/x

35x = 0.025

x = 0.025/35

x = ​7.14*10^-4rand

Hence the cost of 25g is  ​7.14*10^-4rand

Answer:

True

Step-by-step explanation:

12*13=156

12*0.5=6

156+6=162

Then we put a money sign in front and a . point after the 2 and two 0's and we get $162.00

Answer:

  see attached

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships between sides and trig functions. The relevant relations here are ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

In your diagram, leg 'a' is opposite angle α and adjacent to angle β. Similarly, leg 'b' is opposite angle β and adjacent to angle α. The hypotenuse is 'c' in all cases.

So, filling the table is a matter of identifying adjacent and opposite legs. You will notice that the sine of α is the cosine of β and vice versa.

Answer:

9.43 ft

Step-by-step explanation:

First, we need to find the area of the entire circle(shaded & unshaded), which is 12.57, with a radius of 2 ft. Next, we find the area of the white area, and NOT the shaded area, which is 3.14, with a radius of 1 ft. Now, we need to subtract the white area(3.14) from the total area(12.57), which is 9.43.

Hope this helps!

Answer:

R V

1  9π in³ 

2  36π in³

3  81π in³

Step-by-step explanation:

For, r = 1

V = π(1)²9 = 9π in³

For, r = 2

V = π(2)²9 = 4*9π in³ = 36π in³

For r = 3

V = π(3)²9 = 9*9π in³ = 81π in

R V

1  9π in³ 

2  36π in³

3  81π in³

Answer: 3.9ft²

Step-by-step explanation:

Find the area of the rectangle first:

= Length * Width

= 2 * 1.5

= 3 ft²

Find the area of the semi-circle by finding the area of a circle and dividing it by 2:

= πr²

= 3.14 * 1.5/2 * 1.5/2

= 1.76625‬ft²

Divide by 2:

= 1.76625‬/ 2

= 0.88 ft²

Add the area of the rectangle to the semi-circle:

= 3 + 0.88

= 3.9ft²

Answer:

-31104

Step-by-step explanation:

They are each Multiplying by 6 so 5184 which also multiply and add the negative sign so you get -31104

Answer:

x⁴ - 11x² + 28

= x⁴ - 4x² - 7x² + 28

= x²(x² - 4) - 7(x² - 4)

= (x² - 7)(x² - 4)

[tex] = (x - \sqrt{7} )(x + \sqrt{7} )(x - 2)(x + 2)[/tex]

Answer:

1 1/4 kg

Step-by-step explanation:

Maggie made 3kg of fudge. She and her friends ate some and now there are 1 3/4 kg left. How many kg of fudge did maggie and her friends eat?

The kg of fudge thay maggie and her friends ate is calculated as:

Initial kg of fudge - kg of fudge left

= 3 kg - 1 3/4 kg

3/1 kg - 7/4 kg

Lowest common denominator = 4

= 12 - 7/4 kg

= 5/4 kg

= 1 1/4 kg

Answer:

h=3

Step-by-step explanation:

(12-6)/(h--5)=3/4 ~ basic slope equation

6/(h+5)=3/4 ~ simplification

24=3(h+5) ~ multiply both sides by (h+5) and 4 to clear the fractions

24=3h+15 ~ distribute the 3

9=3h ~ subtract 15

h=3 ~ divide by 3

Answer:

Step-by-step explanation:

slope = -3

slope = (h-6)/(8-6) = (h-6)/2 = -3

h-6 = -6

h = 0

Answer:

4:6 or 2:3

Step-by-step explanation:

Let me know if this is correct!

Answer: 3

Step-by-step explanation:

f(x)= -x + 4

Therefore f(-1)= -(-1)+4= 1+4= 5

h(x)= (3/2)x - 1

Therefore h(2)= (3/2)(2) -1= 3-1= 2

f(-1) - h(2)= 5 - 2= 3

Answer:

Yes ; Yes ; Yes it makes sense

Step-by-step explanation:

1.) Lydia used subtraction operator to define and establish a relationship between her best and worst game times ; Hence we could conclude that Lydia is correct as this gives the range between both times.

From the numbers given in the question as their is no graph attached :

4 1/4 - 1 1/2

17/4 - 3/2

(17 - 6) / 4

11 /4

= 2 3/4

The subtracted numbers represent the duration of each of the three times game was played ; Hence the numbers represents the game times.

Yes ; Her conclusion makes sense ; as she was able to deduce the range between her best and worst game time

Step-by-step explanation:

step 1. a circle with r = 2 has area of (pi)r^2 = (pi)(4) = 4pi

step 2. a circle with r = 3 has area of (pi)r^2 = (pi)(9) = 9pi

step 3. the area, A, of a circle is half the sum of the area of the circles with r = 2 and r = 3

step 4. A = (4pi + 9pi)/2 = 13pi/2 = 6.5(pi).

step 5. the answer is not 6.5 but is 6.5(pi) or 6.5 times pi.
