Answer:

50.3 cm³

Step-by-step explanation:

Use the cylinder volume formula:

V = [tex]\pi[/tex]r²h, where r is the radius and h is the height.

Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.

Plug in the radius and height into the equation:

V = [tex]\pi[/tex]r²h

V = [tex]\pi[/tex](2²)(4)

V = 16[tex]\pi[/tex]

V = 50.3 cm³

Answer:

50.3 cm³

Step-by-step explanation:

Use the cylinder volume formula:

V = r²h, where r is the radius and h is the height.

Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.

Plug in the radius and height into the equation:

V = r²h

V = (2²)(4)

V = 16

V = 50.3 cm³

Answer:

61, C

Step-by-step explanation:

So, congruent means all the same. The question is just saying that 3 lines intersect at one point and form 6 angle. The 6 angles are not all the same. Given that, what is the smallest possible largest angle. Obviously, if all angles could be congruent, then, it would be 6 60° angles. However, they aren't. So, to minimize the largest angle, we can just make 1 angle 61° and another 59°. Therefore, the answer should be C which is 61° as you would have the 6 angles being:

59°, 60°, 60°, 60°, 60°, and 61°.

8.7 is greater than 8.5 because the 7 is more than the 5 and the number 5 is less. Hope this helps :)

Answer:

wrong

Step-by-step explanation:

(a+b)^2=(a+b)(a+b)

=a(a+b)b(a+b)

=a^2+ab+ab+b^2

=a^2+2ab+b^2

Answer:

(2x−5)(x−6)

Step-by-step explanation:

2x^2-12x-5x+30

2x(x-6)-5(x-6)

(2x-5)(x-6)

K’: (0, 1)

L’: (-3, 1)

M’: (-2, 3)

N’: (-1, 3)

You are reflecting across the x = 2, so the line is vertical on 2 like |. It’s as many points away on each side for the other side. Ex. K is 2 points to the right of x = 2 so then it would be 2 points to the left of x = 2.

Answer:

Farmer Anne's land = 173 acres

Farmer Cassius = 519 acres

Farmer Mel = 1,557 acres

Step-by-step explanation:

Total acre = 2,249

Let

Farmer Anne's land = x

Farmer Cassius = 3x

Farmer Mel = 3(3x) = 9x

x + 3x + 9x = 2,249

13x = 2,249

x = 173

Farmer Anne's land = x = 173 acres

Farmer Cassius = 3x

= 3(173)

= 519 acres

Farmer Mel = 3(3x) = 9x

= 9(173)

= 1,557 acres

Therefore,

Farmer Anne's land = 173 acres

Farmer Cassius = 519 acres

Farmer Mel = 1,557 acres

Answer:

see below

Step-by-step explanation:

f(x)= -0.08x(x^2-11x+18)

Factor

f(x)= -0.08x(x-9)(x-2)

Using the zero product property to find the zeros

0= -0.08x(x-2)(x-9)

-0.8x =0    x-2 =0  x-9 =0

x=0            x=2           x=9

Multiply out

f(x) =  -0.08 x^3 + 0.88 x^2 - 1.44 x

The highest power is x^3

f(-∞) = -0.08( -∞)^3 = - ( -∞) = ∞

As x goes to -∞  f(x) goes to +∞

f(∞) = -0.08( ∞)^3 = - ( ∞) = -∞

As x goes to ∞  f(x) goes to -∞

Edg 2020

Answer:

B. 8

Step-by-step explanation:

Given the equation, [tex] s = 1.7f - 7.2 [/tex],

where,

s = shoe size,

f = foot length,

To determine the shoe size of a man that has a foot length (f) of 9 in, substitute f = 9 into the equation.

[tex] s = 1.7f - 7.2 [/tex]

[tex] s = 1.7(9) - 7.2 [/tex] (substitution)

[tex] s = 15.3 - 7.2 [/tex]

[tex] s = 15.3 - 7.2 [/tex]

[tex] s = 8.1 [/tex]

His shoe size is approximately 8 inches

Answer:

x = 66/7 & area = 132/7

Step-by-step explanation:

7x-9=0

x=9/7

substitute value of x in 5x-3;

5(9/7)+3=66/7

Then, a*a,

thus, 2(66/7) = 132/7

Answer:

The input when the output is 17 is x=6.

Step-by-step explanation:

Functions

Assume the input is called x and the output is the function f(x). Two times the input is 2x. 5 more than that is 2x+5.

Knowing the output of the function is 5 more than 2 times the input, we can write the function as:

f(x)=2x+5

Now find the input x when the output is 17:

17=2x+5

Swap sides of the equation:

2x+5=17

Subtract 5:

2x=17-5=12

Divide by 2:

x=12/6=6

The input when the output is 17 is x=6.

Answer:

The inverse of a power function of exponent n is a nth root radical function. For example, the inverse of y = 10x^2 is y = √(x/10) (at least for positive values of x and y).

Answer:

It will take the master baker 2.86 hours to finish the remaining order after 2 hours.

Step-by-step explanation:

the time taken for the master baker to fill the order = 6 hours

the time taken for the student baker to fill the order = 8 hours

let the time taken for both to finish the work together if they work at the same rate = x

[tex]\frac{x}{8} + \frac{x}{6} =1\\\\\frac{3x + 4x}{24} = 1\\\\7x = 24\\\\x = \frac{24}{7}\\\\x = 3.43 \ hours[/tex]

After 2 hours, the remaining time for them to finish the work together is given by;

t(remaining) = 3.43 hours - 2 hours = 1.43 hours

Working at the same rate, 2 persons will take 1.43 hours to finish the remaining work.

One person will take hour many hours ?

2 persons working at the same rate  --------> 1.43 hours

1 person working at the same rate -----> ?

= 2 x 1.43 hours

= 2.86 hours

Therefore, it will take the master baker 2.86 hours to finish the remaining order after 2 hours.

Answer: x- intercept: (-2, 0)   y- intercept:  (0,_5)

Step-by-step explanation:

Answer:

Z = A - x - 5

Step-by-step explanation:

A = x + 5 + z

Make the equation equal to z by moving the x and 5 to the side of the = with A. Move the x and 5 by subtracting x and 5 from both sides.

A - x = 5 + z

A - x - 5 = z

So, Z is equal to A - x - 5
