Which expression is equivalent to x^−4 ?

Answer:

The standard deviation of the set is 4.2

Step-by-step explanation:

The standard deviation (sd) for the set is calculated as follows:

sd² = [(x1 - mean)² + (x2 - mean)² + ... ]/N

where x1, x2, et cetera are the values in the set and N is the number of elements in the set. Replacing with data:

sd² = [(2 - 7)² + (4 - 7)² + (6 - 7)² + (9 - 7)² + (14 - 7)²]/5

sd = √17.6

sd = 4.2

Answer:

[tex]6m^{2}[/tex]

Step-by-step explanation:

well we are looking for a face of the rectangular prism.

the front face of the rectangular prism is length times height

which is 3 times 2 = [tex]6^{2}[/tex]

if we did any other face, like the side which is width times height ( 8 meters) it is not one of the answers.

so the only face that can be answers is length times height.

therefore the answer is

6m^2

Answer:

C, factored is either 4(p + 4)^2 or (2p + 8)^2

Step-by-step explanation:

4(p^2 + 8p + 16)

4(p + 4)(p + 4)

4(p + 4)^2

OR

(4p^2 + 32p + 64)

(2p + 8)(2p + 8)

(2p + 8)^2

Answer:

x would equal -11 or 13

Step-by-step Explanation:

x(x - 2) - 143 = 0

x^2 - 2x - 143 = 0

-2x + x^2 = 143

-143 + (-2x) + x^2 = 0

(x - 13)(x + 11)

x - 13 = 0

Add 13 to both sides

x = 13

x + 11 = 0

Subtract 11 from both sides

x = -11

Answer:

45%

Step-by-step explanation:

Let P = be the unknown percent

is means equals and of means multiply

27 = P * 60

Divide each side by 60

27/60 = P60/60

.45 = P

Change to percent form

45% = P

Answer:

Its 45

Step-by-step explanation:

27/60    */100

Cross multiply

27x100

2700

2700/60

=45%

Answer:

62.83 cm squared

Step-by-step explanation:

A = 2πrh+2πr^2

A = 2π(2)(3)+2π(2)^2

A = 2π(6)+2π4

A = 12π+8π

A = 20π

A = 20(3.14)

A = 62.83 cm squared

Answer:

A. (2, 10)

Step-by-step explanation:

If there are two points (x1,y1) and (x2,y2) on a coordinates plane then

coordinates of the midpoint is given by (x1+x2)/2, (y1+y2)/2

__________________________________________________

Given

one endpoint is (–6, 4) and midpoint is (–2, 7)

let coordinates of other endpoint be (x,y)

now if one endpoint is (–6, 4) and other endpoint is (x,y)

then coordinates of midpoint is ((-6+x)/2 , (4+y)/2)

while the coordinates of midpoint given  is  (–2, 7)

thus (–2, 7) should be equal to ((-6+x)/2 , (4+y)/2)

-2 = (-6+x)/2             and   7 = (4+y)/2

=> -2*2 = -6+x                 => 7*2 = 4+y

=> -4 = -6+x                    => 14 = 4+y

=> -4+6 = x                     => 14-4 = y

=> x = 2                           => 10 = y

Thus, coordinates of the other endpoint is(2,10)

Answer:

a = 80

Step-by-step explanation:

This is a right triangle so we can use the Pythagorean theorem

a^2 + b^2 = c^2  where a and b are the legs and c is the hypotenuse

a^2 + 60^2 = 100 ^2

a^2 +3600=10000

Subtract 3600 from each side

a^2 = 10000-3600

a^2 =6400

Take the square root of each side

a = sqrt(6400)

a = 80

Answer:

Result at time x = 4 seconds the soccer ball hit the ground.

Step-by-step explanation:

At the moment just before the ball is kicked, it is on the ground and so the height f(x) is zero meters. After the kick, the ball goes through the air and it's path can be described by a (mountain) parabola.

So lets see after how many second (x) the height = 0 once again.

f(x) = 8x-2x^2

f(x) = 0

8x - 2x^2 = 0

Try to write the formula in two terms

-2x * (x - 4) = 0

When a product of two or more terms equals zero, then at least one of the terms must be zero.

Now solve each term = 0 separately, meaning, solve as many equations as there are terms in the product.

Any solution of term = 0 solves product = 0.

Solve the first term:

-2x = 0

Multiply left an right from the = singn with the factor -1 gives this outcome:

2x = 0

x = 0

Solve the second term:

x-4 = 0

x = 4

Result at time x = 4 seconds the soccer ball hit the ground.

x = 4

x = 0

The additive is what you add to a number to get zero.

The negative of a number.

Example:

The additive inverse of −5 is +5, because −5 + 5 = 0

The additive inverse of +5 is −5, because +5 − 5 = 0

Additive inverses are negated numbers.

The points on the number line are additive inverses.

For a number x, the additive inverse is -x.

The first point on the number line is:

[tex]\mathbf{x = 3}[/tex]

Negate both sides

[tex]\mathbf{-x = -3}[/tex]

-3 represents the additive inverse of 3.

Hence, the points on the number line are additive inverses.

Answer:

x² + (y - 3)² = 9

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (0, 3) and r = 3, thus

(x - 0)² + (y - 3)² = 3², that is

x² + (y - 3)² = 9 ← equation of circle
