12²=(√2d/10)²

144=2d/10

2d=(144)(10)

d=1440/2

Yup! Many people find this counter-intuitive at first because they forget that changes in the direction of motion of an object—even if the object is maintaining a constant speed—still count as acceleration.

Then simplify

7x^2 - 7x + 6

Answer:

errr polynomials ahaha

so basically we can multiply the power outside of the parantheses with the exponents on the inside:

so

[tex]-3x^{2*4} y^{1*4}[/tex]

this will give us:

-3x^8y^4

we also unfortunately, have to use the power on the coefficient -3 as well  and we cant just MULTIPLY -3 by 4, we are going to have to multiply -3 with -3 4 TIMES(anytime we see a coefficient we MUST multiply the coefficient by itself according to the number outside of the parantheses)

so:

-3*-3*-3*-3=81

final expression

[tex]81x^{8}y^{4}[/tex]

Answer:

The value of x is 120°

Step-by-step explanation:

We should draw a line parallel to the given parallel lines and passes through the vertex of the measure x and divides it into two angles of measures x1 and x2, look at the attached figure

In the given figure

∵ The dashed line is parallel to the given line up

∴ The angle of the measure 70° and the angle x1 are alternate angles

∵ The alternate angles are equal in measures

∴ x1 = 70°

∵ The dashed line is parallel to the given line down

∴ The angle of the measure 50° and the angle x2 are alternate angles

∵ The alternate angles are equal in measures

∴ x2 = 50°

∵ x = x1 + x2

∴ x = 70 + 50

∴ x = 120°

∴ The value of x is 120°

Answer:

x= 120

Step-by-step explanation:

Alternated angles  are 50 and 70

The answer is "descriptive statistics".

Step-by-step explanation:

Descriptive statistics are short descriptive factors that add up a production set, that can be either a reflection of a whole or a sample population. It is broken down into cumulative frequency measurements and variance measurements. The study uses descriptive statistics to explain the profile of the respondents. People give simple summaries about the sample as well as the actions.

Answer:

Step-by-step explanation:

Answer:

2x + 19.

Step-by-step explanation:

The reasoning behind this is that one must find the disparity between the first and second expressions - 9x+14 and 7x-5.  To do this, one subtracts 7x-5 from 9x+14.  Set this up as though it were a normal subtraction problem - 9x+14 over 7x-5 with the little subtraction symbol to the left.  When subtracting the negative five from fourteen, one adds the five to the fourteen due to the fact that the five was already negative and as such the negatives cancel out.  The 7x is simply subtracted from the 9x, resulting in 2x.  This leads to 2x + 19.

Answer:

Step-by-step explanation:

z=5

x=9

y=3

plug the numbers into a calculator

(9-3)=6

5^2=25

25*6=150

Step-by-step explanation: To handle these evaluation problems, you must be able to deal with positives and negatives, and you must know your order of operations. In addition, it's a good idea to get into the habit of using parenthses when substituting numbers in for variables.

Notice that we have a set of parenthses in our problem and remember that we use parenthses when substituting our numbers into the problem.

To avoid the confusion of having too many sets of parenthses,

let's change the parenthses in the original problem to brackets.

Now let's substitute using parenthses.

So we have (5)² · [(9) - (3)].

Since the parenthses were in the original problem were replaced

by brackets and parenthses come first in your order of operations,

in our problem the brackets are going to come first.

So first simplify 9 - 3 which is 6.

So we have (5)² [(6)].

Exponents come next so we square the 5 to get 25

and that gives us (25) [(6)] which is 150.

Answer:

x=4; x1=1; x2=-0.8

Step-by-step explanation:

The area of triangle WXY with altitude YZ is: 8 square units.

Area = 1/2(base × height)

Altitude = height.

Given:

Base = WX = distance between W(2, −1) and X(6, 3):

Using distance formula, [tex]WX = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}[/tex]:

[tex]WX = \sqrt{(3 - (-1))^2 + (6 - 2)^2}\\\\\mathbf{WX = 5.7 $ units}[/tex]

Altitude/height = YZ = distance between Y(7, 0), and Z(5, 2):

[tex]YZ = \sqrt{(0 - 2)^2 + (7 - 5)^2}\\\\\mathbf{YZ = 2.8 $ units}[/tex]

Area of triangle WXY = 1/2(WX × YZ)

Area of triangle WXY = 1/2(5.7 × 2.8) = 7.98

Area = 8 square units.

Answer:

S = 83 g and 650 kg.

Step-by-step explanation:

Gram (g)= 1000 kilograms (kg).

Jill (J)= 92000 + 250 kg.

J = 92250 kg

Sister (S) = J - (8000 + 600 kg)

S = 92250 - 8600 kg

S = 83650 kg.

S = 83 g and 650 kg.
