find the volume of the cone

Answer:

f(x)=5x+3

Step-by-step explanation:

The slop is 5 and the y intercept is 3

So if you put that in an equation it makes 5x+3

I used the slope formula to find the slope

Subtract the y values over x values

Answer:

[tex]\frac{49}{28}[/tex]

Step-by-step explanation:

Evaluate g(- 4) and f(- 4) by substituting x = - 4 into g(x) and f(x), that is

f(- 4) = - 10(- 4) + 9 = 40 + 9 = 49

g(- 4) = (- 4)² + 12 = 16 + 12 = 28

Then

[tex]\frac{f(-4)}{g(-4)}[/tex] = [tex]\frac{49}{28}[/tex] = [tex]\frac{7}{4}[/tex]

Answer:

Total weight = 111.6 lbs

Step-by-step explanation:

Given the following data;

Length = 1 feet

Width = 9.5 feet

Height = 13.5 feet

Mass of contents = 0.87 pounds per cubic foot

To find the weight of the contents in the container;

First of all, we would determine the volume of the rectangular prism;

Volume = length * width * height

Volume = 1 * 9.5 * 13.5

Volume = 128.25 cubic feet

Next, we find the overall weight;

Total weight = volume * mass of contents

Total weight = 128.25 * 0.87

Total weight = 111.6 lbs

The right solution  is "[tex]9.7\times 10^{-10}[/tex]".

Step-by-step explanation:

According to the question,

The probability that male professional golfer makes hole in one will be:

[tex]P=\frac{1}{2780}[/tex]

Number of players,

n = 36

and,

[tex]q=1-P=\frac{2779}{2780}[/tex]

By using the Binomial theorem, we get

⇒ [tex]P(x=r) = \binom{n}{r} p^r q^{n-r}[/tex]

Bu substituting the values, we get

                   [tex]=\binom{36}{4} (\frac{1}{2780} )^4 (\frac{2779}{2780} )^{32}[/tex]

                   [tex]=9.74929\times 10^{-10}[/tex]

or,

                   [tex]=9.7\times 10^{-10}[/tex]

Answer:

B. SAS Theorem

Step-by-step explanation:

SAS means that there are 2 corresponding sides with an angle in between. This condition is satisfied in this case because AC corresponds to DF (18/2 = 9), angle c and angle f are congruent, and BC corresponds to EF

By ''SAS theorem'' triangle ABC is similar to DEF.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

To find the theorem which can be used to verify triangle ABC is similar to DEF.

Now,, By figure,

There are one angle are common.

And, Ratio of two sides are equal.

Hence, By ''SAS theorem'' triangle ABC is similar to DEF.

Answer:

x = 30

Step-by-step explanation:

The angle in the bottom right is 120

Call is y

y+60 = 180

y = 180-60

y =120

Opposite angles in a parallelogram are equal so the upper left angle is 120

Call the 3x +z = 120

We also know that 2x+90 +z = 180 since it forms a straight line

Subtract 90 from each side

2x+z = 90

Using 3x+z = 120 and 2x+z =90 and subtracting the second equation

3x+z = 120  

-2x-z =-90

------------------

x = 30

The surface area is 324

Answer:

The surface area of this rectangular prism is 324 [tex]inches^{2}[/tex].

Step-by-step explanation:

The formula for surface area of a rectangular prism is this :

A = 2(wl + hl + hw)

l = 6, w = 5, h = 12.

Now knowing these values, we can solve for A.

A = 2(wl + hl + hw) = 2(5 · 6 + 12 · 6 + 12 · 5) = 324

The surface area of this rectangular prism is 324 [tex]inches^{2}[/tex].

Answer:

$1.918

Step-by-step explanation:

The volume of a right circular cone is obtained using the formular :

V = 1/3πr²h

From the question:

Diameter = 9 inches ; height = 10 inches

Radius = diameter /2 = 9/2 = 4.5 inches

V = 1/3*π*4.5²*10

V = 211.95 in³

Volume in ft³ = 211.95 / 1728 = 0.12265625 ft³

Density of popcorn = 34 ounces / ft³

Density of popcorn CONTAINER = x

1 ft³ = 34 ounce

0.12265625 ft³ = x

Cross multiply

x = 34 * 0.12265625 ft³

x = 4.1703125 ounce

Hence, popcorn continer has a density of 4.1703125 ounce

If price per container = $8

The price per ounce = $8 / 4.1703125

= $1.918

Hence, price per ounce is $1.918

Answer:

y(x) = -1/(x^2 + c_1 x)

Step-by-step explanation:

Solve Bernoulli's equation ( dy(x))/( dx) + y(x)/x = x y(x)^2:

Divide both sides by -y(x)^2:

-(( dy(x))/( dx))/y(x)^2 - 1/(x y(x)) = -x

Let v(x) = 1/y(x), which gives ( dv(x))/( dx) = -(( dy(x))/( dx))/y(x)^2:

( dv(x))/( dx) - v(x)/x = -x

Let μ(x) = e^( integral-1/x dx) = 1/x.

Multiply both sides by μ(x):

(( dv(x))/( dx))/x - v(x)/x^2 = -1

Substitute -1/x^2 = d/( dx)(1/x):

(( dv(x))/( dx))/x + d/( dx)(1/x) v(x) = -1

Apply the reverse product rule f ( dg)/( dx) + g ( df)/( dx) = d/( dx)(f g) to the left-hand side:

d/( dx)(v(x)/x) = -1

Integrate both sides with respect to x:

integral d/( dx)(v(x)/x) dx = integral-1 dx

Evaluate the integrals:

v(x)/x = -x + c_1, where c_1 is an arbitrary constant.

Divide both sides by μ(x) = 1/x:

v(x) = x (-x + c_1)

Solve for y(x):

y(x) = 1/v(x) = -1/(x^2 - c_1 x)

Simplify the arbitrary constants:

Answer: y(x) = -1/(x^2 + c_1 x)

Answer:

Jamie's estimate is correct, since the result is 2.1% less than the estimated number.

Step-by-step explanation:

Given that Jamie says the value of the expression 1.43 x (19/37) is close to 0.75, to determine if Jamie's estimate seems reasonable the following calculation must be performed:

1.43 x (19/37) = X

1.43 x 0.513 = X

0.7343 = X

0.75 = 100

0.7343 = X

0.7343 x 100 / 0.75 = X

97.9 = X

Therefore, Jamie's estimate is correct, since the result is 2.1% less than the estimated number.

Answer:

Logic is the study of how to critically think about propositions or statements that are either true or false.

Logic is very useful in the world of mathematics. Mathematicians use logic all the time to prove theorems and other mathematical facts. Everything we know about math right now is based off of these logical proofs. Without these, we wouldn't have our formulas, like the wonderful quadratic formula or the very useful Pythagorean Theorem.

Using logic in math is about mixing the specific language used in logic with the specific symbols used in math.

Answer:

-1/2

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes.

The solution is, -1/2 is the slope of a line that is perpendicular to the line

shown on the graph.

In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

here, we have,

we have to,

find the slope of the line shown using

the formula, m = y1- y2 / x1- x2

from the given graph we get,

Let

P1(0,1)

P2(1,3)

now we get,

replacing

m = 2/1

   = 2

so, here, m1 = 2

two lines are perpendicular  when

m1 * m2 = -1

as, we know that,

Perpendicular lines have negative reciprocal slopes.

so, we get ,

m2 = -1/2

Hence, The solution is, -1/2 is the slope of a line that is perpendicular to the line

shown on the graph.

Answer:

9x^3 y^5

Step-by-step explanation:

Since the formula to finding area is (L*W = A), we first have to find the width.

Width: 3x^3 y^5 times 2 = 6x^3 y^5

Then we add them. So, 3x^3 y^5 + 6x^3 y^5 = 9x^3 y^5

Answer:

4 litres

Step-by-step explanation:

First, we are going to find 60% of 20 litres.

20 × [tex]\frac{60}{100}[/tex] = 12 litres

∴ Pure milk 12 litres.

Now we find 40% of 20 litres.

20 × [tex]\frac{40}{100}[/tex] = 8 litres

To find the quantity of water to be added we subtract the 8 litres from the 12 litres.

12 - 8 = 4 litres

∴ 4 litres of water should be added so that pure milk becomes 40%
