Final answer:

To solve the equation 4 = 12x - 2, we need to find the value of x. The value that satisfies the equation is x = 1/2.

Explanation:

To find the value of x that makes the equation 4 = 12x - 2 true, we need to solve for x.

12x - 2 = 4

12x = 6

x = 6/12

x = 1/2

So, the value of x that satisfies the equation is x = 1/2.

Step-by-step explanation:

I will assume a circular pizza with 8 pie shaped pieces.

Each of the 8 sectors is one piece of pizza.  So find the area of the the circle, radius = 16/2 = 8, that is π * 8^2 and divide by 8 getting 8π for the area of each slice.  Note:  8π ≈ 8 * 3.1416 ≈ 25.13 in^2.

Answer:

25.13in^2

Step-by-step explanation:

Answer:

78.5%

Step-by-step explanation:

Area of a 100ft radius circle = 628sqm

Area of rectangle = 800sqm

= 172sqm difference in size

if 800 sqm = 100%

Then 600 sqm = 3/4 = 75%

60sqm =3/40 = 7.5%

6sq m =3/400 =0.75%

2 sq m = 0.25%

30sqm = 1/2 of 7.5%= 3.75

3.75-0.25 = 3.50%

3.50% + 75 = 78.5%

Answer:

90 so c

Step-by-step explanation:

The measure of Angle c when  3 lines intersect to form 6 angles is 90 degrees.

For a regular polygon of any number of sides, the sum of its exterior angle is 360° (full angle).

Exterior angle is an measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.Consider that it be having 'n' sides, all the exterior angles are of same measure, and therefore, their measure is (360/n)°.

We are given that;

The 3 lines intersect and form 6 angles.

Now,

To find angle c, we need to use the fact that the angles around a point add up to 360 degrees. The six angles formed by the three intersecting lines include all the angles around a point, so we have to set up another equation;

Angle c + 48 degrees + 42 degrees + 90 degrees + 48 degrees + 42 degrees = 360 degrees

Simplifying and solving for angle c, we get:

Angle c = 360 degrees - 270 degrees

Angle c = 90 degrees

Therefore, by interior and exterior angles the measure of angle c is 90 degrees.

Answer:

all real number

Step-by-step explanation:

since h(x) is polynomial function

Final answer:

The domain of the function h(x)=x-4 is all real numbers, as there are no restrictions on the value of x.

Explanation:

The domain of a function represents all the possible values that can be input into the function. For the function h(x)=x-4, there are no restrictions on the value of x, since x represents a real number and there are no denominators or square roots to consider.

Therefore, the function h(x)=x-4 is defined for all real numbers, making the domain of h to be all real numbers, which is often denoted by the symbol (-∞, +∞) or simply written as 'all real numbers'.

Answer: The radius of the circle in 11

Final answer:

The equation is in the standard form (x - h)² + (y - k)² = r², where r is the radius. Thus, the square root of the constant term 121 would give the radius, which is 11.

Explanation:

To find the radius from an equation of a circle in the form (x - h)² + (y - k)² = r², where (h, k) is the center of the circle, and r is the radius, we need to compare it to the given equation.

As per the standard form, the number on the right side of the equation is r², the square of the radius.

We have (x - 3)² + (4 + 4)² = 121, which can be written as (x - 3)² + (8 - 0)² = 121, considering (3,0) as the center of the circle, the radius would be the square root of 121, which is 11.

7 cupcakes=17.5

40-17.5=22.5

donuts are 1.50

22.5 divided by 1.5 is 15

The maximum number of donuts Cooper can buy is 15.

Given that, the cost of cupcakes = $2.50 and the cost of donuts = $1.50.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Let the number of cupcakes be x and the number of donuts be y.

Cooper wans to buy a minimum of 18 cupcakes and donuts altogether

That is, x+y≥18

Cooper has $40 to spend on cupcakes and donuts.

So, 2.50x+1.50y≤40

Cooper decided to buy 7 cupcakes

Then number of donuts will be

2.50(7)+1.50y≤40

⇒17.5+1.50y≤40

Subtract 17.5 on both the sides of a inequality, we get

17.5+1.50y-17.50≤40-17.50

⇒1.50y≤22.5

Divide 1.50 on both the sides of a inequality, we get

1.50y/1.50≤22.5/1.50

⇒y≤15

Therefore, the maximum number of donuts Cooper can buy is 15.

Answer: -3

Step-by-step explanation: plug -2 into f(x)=x^2+10 and you get 14, then plug the -1 into that same equation and end up with 11, now you subtract the 11 from the 14 and get 3 but since you subtracted or in other words the number decreased it would be -3

The average rate of change of f(x) over the interval [-2,-1] is 3.

To find the average rate of change of f(x) over the interval [-2,-1], we need to calculate the difference in the function values at the endpoints and divide it by the difference in the x-values. Let's substitute the endpoints into the function:

f(-2) = (-2)² + 10 = 4 + 10 = 14

f(-1) = (-1)² + 10 = 1 + 10 = 11

The difference in function values is 14 - 11 = 3, and the difference in x-values is -1 - (-2) = -1 + 2 = 1. Therefore, the average rate of change is 3/1 = 3.
