The circumference of circle is 150.72 millimetres.

In simpler terms, circumference in the perimeter of circle. Thus, it will represent the measure of length of the line of circle. The relationship between circumference of circle and it's diameter will be represented as formula -

C = πd, where C is circumference and d is diameter.

Keep the value of diameter in the formula to find the exact circumference of the circle.

Circumference = 3.14×48

Performing multiplication to find the circumference of the circle

Circumference = 150.72 millimetres.

Therefore, the circumference of the circle with 48 millimetres diameter is 150.72 millimetres.

Answer:

The height will reach 128 feet after 1 second.

The object will reach the ground after 3 seconds.

Step-by-step explanation:

Plug in the height into the equation: h(t)=144-16t^2

Solve for t.

Ex:

128=144-16t^2, subtract 144 on both sides

-16=-16t^2, divide -16 on both sides

1=t^2, find the square root of both sides

1=t

Answer:

Perpendicular

Explanation:

Given the coordinates

A(-2,-5), B(4.7) C(0, 2) and D(8,-2)​, we are to determine whether AB is parallel, perpendicular to CD or neither

To do this, we need to find he slope of AB and CD first. Using the formula for calculating slope as shown;

m = y2-y1/x2-x1

For AB:

slope = 7-(-5)/4-(-2)

Slope = 7+5/4+2

Slope of AB = 12/6

Slope of AB = 2

For CD

Slope of CD = -2-2/8-0

Slope of CD = -4/8

Slope of CD = -1/2

Note that for AB to be perpendicular to CD, the product of their slope must be -1.

Given

mAB = 2

mCD = -1/2

Taking their product

mAB * mCD = 2 * -1/2

mAB * mCD = -1

Since the product is -1, hence AB is PERPENDICULAR to CD

Since the cost of each medium pizza is $7, then

Assume that the number of pizzas is x and the total cost is y, then

Multiply x by x to find y

The algebraic rule is

a) Let us complete the table

x: Process: y

0 0 x 7 = 0 0

1 1 x 7 = 7 7

2 2 x 7 = 14 14

3 3 x 7 = 21 21

4 4 x 7 = 28 28

a) We need to find the cost of 10 pizzas, then

Substitute x by 10 in the algebraic rule

The cost of the 10 pizzas is $70

b) If you have exactly $84, then substitute y by 84 to find x

Divide both sides by 7 to find x

You can buy 12 pizzas buy $84

c) If you buy 0 pizza, then the cost of it is

Since zero multiplied by any number give zero

The cost of zero pizza is zero

Because 0 x $7 = $0

Exponent

Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.

We are given two numbers [tex]7/10^2[/tex] and [tex]7/10^3[/tex].

We have to find the relationship between the two given numbers.

We know that,

[tex]7/10^2[/tex] can be written as 7/100 and [tex]7/10^3[/tex] can be written as 7/1000.

We can write,

7/1000 = (7/100) *(1/10)

Hence, 7/1000 is one-tenth of 7/100.

Also, we can write,

7/100 = (7/1000)*10

Step-by-step explanation:

Congruent angles are two or more angles that are identical to each other.  the measure of these angles is equal to each other. The type of angles does not make any difference in the congruence of angles, which means they can be acute, obtuse, exterior, or interior angles.

Given:

To Determine: The value of x

Solution

Solve the derived equation by factorizing completing

Therefore

Hence, the value of x is 0.693

The given equation is

This equation belongs to an uptrend line because the variable x is positive. The line has to have a y-intercept at -1 because that's the constant term.

Following the characteristics of the equation, we can deduct that the correct graph is A.

Using the properties of parallel lines we find the value of x is 9 and the value of y is 13.

In geometry, parallel lines are coplanar, straight lines that never intersect.

15). In the given figure the two angles represented by 12x+1 and 15x -26 are equal. as they are alternate exterior angles.

We know from the property of parallel lines that they are equal.

Therefore:

12x+1 = 15x -26

or, 12x-15x = -26-1

or, -3x = -27

or, x = 9

Therefore the angles are 12x + 1 = 109

Now,

109 + 4y-9 +28 =180

or, 4y = 180 - 128

or, y = 13.

Therefore as the line l and m are parallel the value of x is 9 and the value of y is 13 .

The two other linear factors of the polynomial when it is given that k = -1 is a  zero of the given polynomial are  (x+1)(x-4)

In the above question, A cubic polynomial is given as follows

P(x) = [tex]x^{3}[/tex] - 2[tex]x^{2}[/tex] - 7x - 4

K = -1

We need to find the, linear factors of the polynomial when it is given that k = -1 is a  zero of the given polynomial

So, we got that ( x +1 ) is a one linear factor of P(x). As the highest degree of the polynomial is 3 so there will be three zeroes of the given polynomial. Therefore, We need to find others two

If we divide P(x) = [tex]x^{3}[/tex] - 2[tex]x^{2}[/tex] - 7x - 4 by ( x + 1 ) by long division method we'll get, [tex]x^{2}[/tex] -3x - 4

Now we'll solve the quotient by squaring method, to get the other two

Let's say h(x) =  [tex]x^{2}[/tex] -3x - 4

h(x) =  [tex]x^{2}[/tex] -3x - 4

h(x) =  [tex]x^{2}[/tex] -( 4 -1) x - 4

h(x) =  [tex]x^{2}[/tex] -4x + x - 4

h(x) =  x( x-4) + 1( x -4 )

h(x) =  (x+1)(x-4)
