Answer:

the height is 15

Answer:

B) 15

Step-by-step explanation:

Volume of a cone formula:

V = πr²(h/3)

D/2 = r

10/2 = r

r = 5

393 = (3.14)5²(h/3)

393 = 78.5(h/3)

h = 15.02

h = 15

We need to know the Angle subtended by the slice at the center of the pizza i.e. Θ, Radius of the pizza i.e. r about each slice of pizza in order to calculate which one had a larger area.

Area is defined as the quantity that expresses the extent of a region on the plane or on a curved surface.

Area of sector [tex]=\frac{\theta}{360}\pi r^2[/tex]

Here,

Θ = angle subtended by the arc at the center.

We have,

Slice of pizza,

So,

As per the mentioned formula,

we need to know,

So, that we can calculate the area of the slice or pizza.

i.e.

Area of slice [tex]=\frac{\theta}{360}\pi r^2[/tex]

Hence, , we can say that the We need to know the Angle subtended by the slice at the center of the pizza i.e. Θ, Radius of the pizza i.e. r about each slice of pizza in order to calculate which one had a larger area.

-2x² - 8x + 15 = 0

Step-by-step explanation:

Given the following algebraic expression;

x² – 7x + 5

-3x² - x + 10

To add the equation together;

x² – 7x + 5 + (-3x² - x + 10) = 0

x² – 7x + 5 - 3x² - x + 10 = 0

Collecting like terms, we have;

(x² - 3x²) - (7x + x) + (5 + 10) = 0

-2x² - 8x + 15 = 0

Answer:

x = 25

Step-by-step explanation:

By the property,

Equal chords subtend equal angles at the center of the circle. Therefore, measures of arcs having equal central angles will be equal.

2x + 4x + (3x + 30) + (3x + 30) = 360°

(2x + 4x + 3x + 3x) + (30 + 30) = 360

12x + 60 = 360

12x = 300

x = [tex]\frac{300}{12}[/tex]

x = 25

Step-by-step explanation:

Point 1

(xA,yA)= (9, 8)

Point

(xB,yB) = (5, 3)

Formula :

Distance between two points =

√(xB−xA)2+(yB−yA)2

Solution :

Distance between two points =

√(5−9)2+(3−8)2= √(−4)2+(−5)2= √16+25= √41 = 6.4031

Distance between points (9, 8) and (5, 3) is 6.4031

Answer:

58

Step-by-step explanation:

The angles inside a triangle always sum to 180°. We already have a 32° angle and a 90° - totalling 122° - and when we add x°, we'd like the sum to be 180°. So x must be 180 - 122 = 58.

Answer:

58

Step-by-step explanation:

The total should be 180 degrees. We know the the top angle is 32 degrees and the bottom left is 90 degrees because it has a square there. So 32+90=122. If we subtract 122 from 180 we are left with 58 degrees so x=58

Answer:

  a) x = {-1, 3, 4}

  b) (0.472, 13.128)

  c) (3.528, -1.128)

  d) x < 0.472 U x > 3.528

  e) 0.472 < x < 3.528

Step-by-step explanation:

This is a cubic (odd degree) function with a positive leading coefficient, so it will be increasing until the first turning point, and after the last turning point. It will be decreasing between the turning points.

a) A graph shows the zeros to be x = -1, x = 3, x = 4.

b) A graph shows the local maximum to be approximately (0.472, 13.128). The x-coordinate of this point is exactly 2-√(7/3).

c) The local minimum is about (3.528, -1.128). Its x-coordinate is exactly 2+√(7/3).

d) As stated above, the increasing intervals are (-∞, 0.428) ∪ (3.528, ∞).

e) The decreasing interval is (0.428, 3.528).

Additional comments

The sum of odd-degree term coefficients is the same as the sum of coefficients of even-degree terms, so you know one of the roots is -1. Factoring that out gives the quadratic x^2 -7x +12 = (x -3)(x -4), so the other two roots are 3 and 4.

The derivative is 3x^2 -12x +5 = 3(x -2)^2 -7, so its roots (turning points of f(x)) are 2±√(7/3).

I find a graphing calculator can show me the roots and turning points easily.

Answer: x=5

Explanation:

Rearrange the equation

42-x=37 is the same as 37+x=42

Isolate the variable x by subtracting 37 from both sides

37-37 cancels out and 42-37 is 5

X=5 is what you’re left with

Answer:

The volume of the Cylinder is 424.1 Cubuc centimeter.

Step-by-step explanation:

The formula to find the volume of a cylinder is,

[tex]v = \pi \times {r}^{2} \times h[/tex]

Where V is the volume, R is the radius And H is the hight of the Cylinder.

So, in this case, you have

[tex]r = 3cm[/tex]

Because

[tex]radius \: = \frac{diameter}{2} [/tex]

[tex]h = 15cm[/tex]

[tex]v = \pi \times {r}^{2} \times h[/tex]

[tex]v = \pi \times (3cm)^{2} \times 15cm[/tex]

[tex]v = \pi \times 9cm^{2} \times 15cm[/tex]

[tex]v = 424.cm ^{3} [/tex]

Therefor, the volume of the Cylinder is 424.1 Cubic centimeter.
