Given The Diagram Below, What Is MD?

Answers

Answer 1

Answer:

A

Step-by-step explanation:

Answer 2

Answer:

A. 72

Step-by-step explanation:

There are two ways to solve this problem. First of all, this quadrilateral is a trapezoid because the top two angles are congruent and there is one pair of parallel lines. One way to solve the problem is to remember all trapezoids have a measure of 360. So, mD=360-(108+108+72); this equals 72. Additionally, in a trapezoid, the bottom two angles are always congruent; therefore, angle D must equal 72 degrees.

Step-by-step explanation:

Arc GHJ is 81*2= 162 (the arc measure of an inscribed angle that does not cross the center of the circle is 2 times the measure of the angle

since arc GH is 84 and we need HJ, subtract 84 from 162=78

Answers

Answer:

m∡P = 40°

Step-by-step explanation:

15m + 17 + 4m - 10 + 7m - 9 = 180

26m - 2 = 180

26m = 182

m = 7

∡P = 7(7) - 9 = 49 - 9 = 40

Step-by-step explanation:

Plug in 2 for x

(2)^3+6(2)^2+3(2)-5=

Answer:

B

Step-by-step explanation:

Remark

F(2) means that wherever you see an x on the right side of the equal sign, you substitute 2 for.

Suppose the question was f(2) = 3x + 5

Put a 2 where the x is.

f(2) = 3*2 + 5

f(2) = 6 + 5

f(2) = 11

Equation

f(x) = x3 + 6x2 + 3x -5.

Solution

f(2) = 2^3 + 6*2^2 + 3*2 - 5

f(2) =  8 + 6*4 + 6 - 5

f(2) = 8 + 24 + 1

f(2) = 33

Yes it is! To find slope you need to find the rise over run, which you can see it rises up 2 times and over once, so 2/1 which is equal to 2 :)

Answer:

Slope (m) = 2

Step-by-step explanation:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

consider 2 points - (20,20) and (30,40)

[tex]m = \frac{40-20}{30-20}[/tex]

[tex]m=\frac{20}{10}[/tex]

[tex]m=2\\[/tex]

∴ Slope (m) = 2

The length of a rectangle is 3 yards less than 5 times the width. If the perimeter is 102 yards, find the length and the width of the rectangle.

Answers

Answer:

Width = 9 yards, length = 42 yards

Step-by-step explanation:

Perimeter = 2xlength + 2xwidth. Let's call length L and width W. The question also states that L = 5W-3. Therefore, 102 = 2x (5W-3) + 2W. Then, 102 = 12W - 6. 108 = 12W, so W = 9 yards. Since L = 5W - 3, we get 45-3 = 42 yards.

W = 9 yards L= 42 yards

Which of the following are mathematical sentences? Check all that applu
A. 4- d= 12
B. 4-V> 2
C. 3 + 2
D. 59
E. 6 + a = 13
F. 12x

Answers

Answer:

The correct options are:

A, B, and E.

Step-by-step explanation:

A mathematical sentence (or a mathematical statement) is a sentence that can be true or false.

This is the only criteria we need to check, now let's analyze each option.

A: 4 - d = 12

This can be true or false, for example, if d = 0 the sentence is false because:

4 - 0 = 12

4 = 12 is false.

and if d = -8 the sentence is true, because:

4 - (-8) = 12

4 + 8 = 12

12 = 12

is true.

B: 4 - V > 2

This sentence can be true or false, same reasoning as before, we can find values of V such that this is true or false.

C: 3 + 2

Now, here we can't say if this is true or false, so this is not a mathematical sentence.

D: 59

Same as before, this is just a number.

E: 6 + a = 13

This can be true or false, depending on the value of a, then this is a mathematical sentence.

F: 12*x

Here we can not say if this is true or false, so this is not a mathematical sentence.

The correct options are:

A, B, and E.

Answer:

Step-by-step explanation:

[tex]g(x)= 4x^2 + 4x + 2[/tex]

[tex]h(x)= 3x^2 - 3[/tex]

[tex]f(3)[/tex]

We have:

[tex]f(x)= - 4x-4[/tex]

Substitute [tex]x = 3[/tex]

[tex]f(3) = -4 * 3 - 4[/tex]

[tex]f(3) = -12 - 4[/tex]

Using the following data set calculate the mean 9,14,14,9,20,6,8,19,17,13,9

Answers

12.545 is the answer

Answer:

12.54

Step-by-step explanation:

When finding the mean, first you add all the numbers in the data:

9+14+14+9+20+6+8+19+17+13+9=138

And then you divide it by the following numbers in the set. In this data set, since there are 11 numbers, you would divide 138 by 11.

138\11=12.5454545

So the answer would be 12.54 if your rounding to the nearest hundred. If your rounding it by a whole number, it would be 13.
