Graph the ellipse with equation x2/9+y2/16 = 1

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:

Given

Diameter of round pizza [tex]d=16\ in.[/tex]

Side of square pizza [tex]a=15\ in.[/tex]

Area of circle [tex]\pi r^2[/tex]

The area of a square is [tex]a^2[/tex]

[tex]\therefore \text{Area of round Pizza}=\pi \times (\frac{16}{2})^2\\\Rightarrow A_1=\pi \times 8^2=201.088\ in.^2[/tex]

The area of square pizza is

[tex]A_2=15^2=225\ in.^2[/tex]

Clearly, the area of square pizza is more and the difference in their area is

[tex]\Rightarrow A_2-A_1=225-201.088=23.91\approx\ 24\ in.^2[/tex]

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:

(3, -4)

Step.

The coordinates of the point which lies on the equation is A ( 3 , -4 )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

y + 4 = 4 ( x - 3 )   be equation (1)

when x = 3 and and y = -4

Substituting the values of x and y in the equation , we get

-4 + 4 = 4 ( 3 - 3 )

0 = 4 ( 0 )

0 = 0

Therefore , the point A ( 3 , -4 ) lies in the equation

Hence , the coordinates of the point is A ( 3 , -4 )

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

6 feet and 10 feet are the possible measurement of the  third side.

A triangle is a three-sided polygon that consists of three edges and three vertices.

To determine the possible measurement of the third side of the sail, we can use the triangle inequality theorem,

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Let's check the answer choices using the triangle inequality theorem:

A. 15 + 8 > 6

23 > 6

This is true, so 6 feet could be a possible measurement of the third side.

B. 15 + 8 > 10

23 > 10

This is true, so 10 feet could be a possible measurement of the third side.

C. 15+8 > 23

23=23

This is false, so 23 feet is not possible measurement of the third sid

D. 15+8 > 30

23>30

This is false, so 30 feet is not possible measurement of the third side

Hence, 6 feet and 10 feet are the possible measurement of the  third side.

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,

#SPJ2

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
