Answer:

The next step is to find the point on the circle which makes a tangent line that passes through the outside point.

Step-by-step explanation:

A tangent line to a circle is a line that touches the circle at exactly one point. You need two points to draw a line. You already have one point and the circle, then you need the other point, which lies on the circle. These two points have to lie on the same line. Notice that there are two possible tangent lines.

Answer:

connect the center of the circle to the point outside the circle

Answer:

A

Step-by-step explanation:

E2021

Answer:

w⁴ - 36

=> ( w² )² - ( 6 )²

=> ( w² + 6 ) ( w² - 6 )

=> w² + 6 = 0 and w² - 6 = 0

=> w = √-6 and w = √6

The value of w is √-6 and √6 .

An identity is an equation that is true for all values of the variables.

For example:

The above equation is true for all possible values of x and y, so it is called an identity.

According to question one such identity will be used

[tex]a^{2} - b^{2} = (a+b)(a-b)[/tex]

w⁴ - 36

= ( w² )² - ( 6 )²

= ( w² + 6 ) ( w² - 6 )

= w² + 6 = 0 and w² - 6 = 0

= w = √-6 and w = √6

Hence, w is a quadratic term so it have two value √-6 , √6 .

Answer:

64pi

Step-by-step explanation:

To find the raidus we divide the diameter by 2

Radius = 16/2 = 8

Area = pi*8^2 = 64pi

Answer:

64pi

Step-by-step explanation:

Answer:

D.

Step-by-step explanation:

area of a square = side^2

area of a cube = 6 x side^2

let the side be a .

6a^2 = 600

=> a^2 = 600/6

=> a^2 = 100

Hence the area of one of its faces is 100 square inches.

or in plain terms without using those formulas,

6 faces of the cube have 600 square inches

=> 1 face of the cube has 600/6 = 100 square inches

Answer: 20 servings

Step-by-step explanation:

From the question, Sara is having a dinner party for four friends and she needs to reduce the serving size of the meatloaf recipe. Sara used the equation x/4=5 . To get the number of servings the recipe originally made, we have to find the value of x.

x/4 = 5

x = 4 × 5

x = 20

This means that the recipe that was used originally made 20 servings.

Answer:

Missing value is -4/3 and whole solution can be written as  ( 8,-4/3)

Step-by-step explanation:

Given equation 2x+3y=12

solution ( 8,)

solution is form (x,y) hence in (8,) x is given as 8 while y  is missing to find y

we will plug 8 as value of x in equation  2x+3y=12. From this equation we will find the missing value.

2x+3y=12

=> 2*8+3y=12

=> 16 + 3y = 12

=> 3y = 12-16= -4

=> y = -4/3

Thus, missing value is -4/3 and whole solution can be written as  ( 8,-4/3)

Step-by-step explanation:

Answer:

Interpreting as: 2(a+b)=-8.1

Input:

2 (a + b) = -8.1

In Given the expression

                               2( a + b) = 8.1  ..........................(1)

now divide both sides of the first equation by 2 ,

                         2 (a + b) /2 = 8.1 /2

                        (a + b) = 4.05

expression    -0.5(a + b) ................(2)

 simply put the value of (a + b) in (2),

                          - 0. 5( 4.05) = -0.5 * 4.05

                                          = 2.025

Value of expression is 2.025.

Answer:

B. -8 and 8

Step-by-step explanation:

To solve this equation, we need to get x by itself. To do this, perform the opposite of what is being done to the equation. Keep in mind everything must be done to both sides of the equation.

x^2=64

x is being squared. The opposite of being squared is taking the square root. Take the square root of both sides.

√x^2=√64

The exponent and square root on the left will cancel, and x will be left by itself.

x=√64

x=±8

The solutions of the equation are x=8 and x= -8

Therefore, the answer is B. -8, 8
