PLEASE HELP QUICK!!!find The Volume Of The Cone. Either Enter An Exact Answer In Terms Of Pi Or Use 3.14

Answers

Answer 1
The answer is 50pi.
Answer 2

The formula for the volume of a cone is [tex]V=\pi r^2\frac{h}{3}[/tex]

Plug in the values we know.

[tex]V=\pi (5)^2\frac{6}{3}[/tex]

[tex]V=\pi*25*2[/tex]

[tex]V=50\pi[/tex]

[tex]V=157[/tex]

^ If 3.14 was used for [tex]\pi[/tex]

Hope this helps.

Given the function f(x)=2x-4 find x if f(x)=10

Answers

Answer:

7

Step-by-step explanation:

Since f(x)=10 is equivalent to f(x)=2x-4, make these equations equivalent. Add 4 to both sides, and simplify to get 2x=14. Divide both sides by 2 to get 7 as your answer.

Answer:

x = 7

Step-by-step explanation:

Given

f(x) = 2x - 4 and f(x) = 10, then equating gives

2x - 4 = 10 ( add 4 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

ugh no body knows this? Suppose a square garden represented by 16x2 ft2. a. What is the length of each side? b. What is the perimeter of the garden? c. If each side was increased by 5 feet what would be the new perimeter?

Answers

Answer:

A. [tex]4x[/tex]

B. [tex]16x[/tex]

C. [tex]16x+20[/tex]

Step-by-step explanation:

A square's area will be the length of each side squared (that's why it's called squared).

Since we know the area, we can find the square root of [tex]16x^2[/tex] to find the length of each side.

We know that [tex]4^2 = 16[/tex] and [tex]x^2 = x^2[/tex], so [tex]4x\cdot 4x[/tex] should be equal to [tex]16x^2[/tex].

This means the side length is [tex]4x[/tex].

The perimeter of a square will be 4 times it's side length. We know the side length, so the perimeter is [tex]4x \cdot 4 = 16x[/tex].

If we added 5 to the length of each side, the new side length would be [tex]4x + 5[/tex]. Again, the perimeter is 4 times the side length so the perimeter would be [tex]4(4x + 5) = 16x + 20[/tex].

Two forces are given by j = (-2,1] and K = (-5,3), in
Newtons. What is the magnitude of j+k ?

Answers

Answer:

[tex]\sqrt{65}[/tex]

Step-by-step explanation:

The magnitude of a vector < x, y > is calculated as

| < x, y > | = [tex]\sqrt{x^2+y^2}[/tex]

Thus

j + k = < - 2, 1 > + < - 5, 3 > = < - 2 - 5, 1 + 3 > = < - 7, 4 >

Then

| < - 7, 4 > | = [tex]\sqrt{(-7)^2+4^2}[/tex] = [tex]\sqrt{49+16}[/tex] = [tex]\sqrt{65}[/tex]

D is between C and E, CD = x 2 , CE = 32-2x, and DE = 12x. Find CD, DE, and CE.

Answers

Answer:

CD = 4DE = 24CE = 28

Step-by-step explanation:

The segment addition theorem tells you ...

  CD +DE = CE

  x^2 +12x = 32 -2x

Subtract the right side to put this in standard form.

  x^2 +14x -32 = 0

  (x +16)(x -2) = 0

  x = -16 or 2

In order for DE to have a positive length, we must have x > 0. So ...

  CD = x^2 = 2^2 = 4

  DE = 12x = 12(2) = 24

  CE = 32 -2x = 32 -2(2) = 28

Answers

Answer:

2y=x+16

Step-by-step explanation:

condition for a perpendicular line to the previous line is that the gradient M1=-1/M2. looking at the question above the equation of the line given y=-2x+3 that is the first M1=-2. so to get the gradient M2 of the line perpendicular, then M2=-1/-2=1/2. so M2=1/2. so the equation of the new line is y=1/2x+C. so we can find C. since the line passes through (-4,6). when x=-4, y=6, 6=1/2(-4)+C..C=6+2=8. so the equation of the new line y=1/2x+8 we can multiply via 2. so we have 2y=x+16

the equation is 2y=x+16

An angle measures 50° less than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer:

20° and 70°

Step-by-step explanation:

Complementary angles sum up to 90°.

The angle = x

Its complement = x + 50

x + x + 50 = 90

2x = 40

x° = 20°

20+50=70

Answer: 70°  and 20°

Step-by-step explanation:

Complementary angles add up to 90 degrees  and we now that one angles measure is 50 degrees less than the other. So we can represent it by the expression   x = y -50    where x  and y are the two angles. We don't the value of y so it will be just y .

Now we know that if we add them,they will equation 90 degrees so we can represent it by the equation,

y + y-50 = 90  Now solve for y

2y - 50 = 90  

      +50  +50

2y = 140

y = 70  

Now we know one angles is 70 degrees and the other is 50  less than it so the other angle will be   70 - 50 = 20

[tex]\boxed{\bold{\huge{\boxed{Area\ of\ Trapezium = 150\ cm\²}}}}[/tex]

Step-by-step explanation:

Using Pythagorean Theorem first to find EC

[tex]\sf CB^2 = EB^2+EC^2\\Where \ CB = 13 \ and \ EB = 5 \\13^2 = 5^2 + EC^2 \\169 - 25 = EC^2 \\EC^2 = 144\\Taking \ sqrt \ on \ both \ sides\\EC = 12 \ cm[/tex]

Given that:

AE = EC

AE = 12 cm

Now,

AB = AE + EB

AB = 12 + 5

AB = 17 cm

ABCD is a trapezoid / trapezium

So,

Area of Trapezium = [tex]\sf \frac{AB+DC}{2} (EC)[/tex]

Where AB = 17 , DC = 8 and EC = 12

Area of Trapezium = [tex]\sf \frac{17+8}{2} ( 12)[/tex]

Area of Trapezium = (25)(6)

Area of Trapezium = 150 cm²
