Answer:

5.2 cubic ft

Step-by-step explanation:

took the test

The volume of given cone is 5.23 cubic feet.

Volume is the measure of the capacity that an object holds.

[tex]v = \frac{1}{3} \pi r^{2} h[/tex]

where,

v is the volume of cone

r is the radius of cone

h is the height of cone

According to the question we have

Diameter of cone is 2ft

⇒ radius of the cone = [tex]\frac{2}{2} = 1 feet[/tex]

Height of the cone is 5ft.

Therefore,

The volume of the cone  = [tex]\frac{1}{3}(1)\pi( 1)^{2} (5)[/tex]

Volume of cone = [tex]\frac{1}{3} (3.14)(1)(5) = 5.23 cubic feet[/tex]

Hence, hence the volume of given cone is 5.23 cubic feet.

Answer:

angle 1 is = 124 angle 2 is = 56

Step-by-step explanation:

supplementary angles always add up to 180 so you can set up the equation (2x+2)+(x-5)=180 to find x. After solving you get x = 61 and then once you have x you plug it into the 2 equations you got for the angles to solve for 1 and 2.

Answer:

for f(3)=2 is y=(2/3)x

Step-by-step explanation:

y=ax

and plug x and y into the parent function.

Answer:

Step-by-step explanation:

f(0) = 6 means y-intercept b = 6

So we have:

                  f(x) = mx + 6     and   f(3) = 2

        So:

                2 = m×3 + 6

                  3m + 6 = 2

                   3m = 2 - 6

                   3m = -4

                    m = -⁴/₃

Therefore the function:

Answer:

x=28°

Step-by-step explanation:

2x+3x-10+50=180

5x+40=180

5x=180-40

5x=140

x=140/5

x=28°

The angle measure of a triangle are shown in the diagram.

What is the value of x?

As, In a triangle measure of all three angles is always 180°.

[tex] \sf : \implies \angle A + \angle B + \angle C = 180\degree[/tex]

[tex] \sf : \implies 50\degree + (2x)\degree + (3x - 10)\degree = 180\degree[/tex]

[tex] \sf : \implies 50 + 2x + 3x - 10 = 180\degree[/tex]

[tex] \sf : \implies 40 + 5x = 180\degree[/tex]

[tex] \sf : \implies 5x = 180\degree - 40\degree[/tex]

[tex] \sf : \implies 5x = 140\degree[/tex]

[tex] \sf : \implies x = \cancel{\dfrac{140\degree}{5}}[/tex]

[tex] \sf : \implies x = 28\degree[/tex]

[tex] \large \underline{\boxed{\bf{x = 28\degree}}}[/tex]

Hence, value of x is 28°.

Answer:

3 rd one

Step-by-step explanation:

The conic section represented by the given equation is Circle.

Circle is a two dimensional figure which consist of set of all the points which are at equal distance from a point which is fixed called the center of the circle.

Standard form of a circle is,

(x - h)² + (y - k)² = r²

where, (h, k) is the center of the circle and r is the radius of the circle.

Expanding, we get,

x² - 2hx + h² + y² - 2ky + k² = r²

x² - 2hx + y² - 2ky + (h² + k² - r²) = 0

The given equation is,

5x² – x + 5y² – 3y + 4 = 0

This is same as the standard form of the circle.

Hence the given equation is that of a circle.

Answer:

A

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

(h, k) are the coordinates of the vertex and a is a multiplier

Given

f(x) = - 2x² - 12x - 16

To complete the square the coefficient of the x² term must be 1

Factor out - 2 from - 2x² - 12x

f(x) = - 2(x² + 6x) - 16

add/ subtract ( half the coefficient of the x- term )² to x² + 6x

f(x) = - 2(x² + 2(3)x + 9 - 9 ) - 16

     = - 2(x + 3)² + 18 - 16

     = - 2(x + 3)² + 2 ; y = 2
