Can someone help me on #7 and #9? It is to find x and y in a parallelogram. Thanks! Will give 12 points.

Answer:

72°

Step-by-step explanation:

Given

Zy = 108°

Zx = ?

We know

Zx + Zy = 180° {being supplementary angles }

Zx + 108° = 180°

Zx = 180° - 108°

Zx = 72°

Hope it will help :)

Answer:

B

Step-by-step explanation:

Essentially, the -3 in this equation is the slope, and when you multiply slope by -1 you are reflecting over the x axis.

Answer:

$57400

Step-by-step explanation:

Given data

P= $10,000

R= 6%

T= 30 years

Let us Assume the investment is compounded Anually

A= P(1+r)^t

A=10000(1+0.06)^30

A=10000(1.06)^30

A=10000*5.74

A=$57400

Hence the Final Amount after 30 years compounded anually is $57400

Answer:

Answer:

4

Step-by-step explanation:

Using Euler's rule for polyhedra

F + V - E = 2 ( F - faces, V- vertices, E- edges )

10 + V - 12 = 2

V - 2 = 2 ( add 2 to both sides )

V = 4

Answer:

The answer is -(4/5)y - 3.

Step-by-step explanation:

The steps are :

[tex] \frac{1}{5} y - \frac{3}{5} y + 5 - \frac{2}{5} y - 8[/tex]

[tex] = ( \frac{1 - 3 - 2}{5} y) + (5 - 8)[/tex]

[tex] = - \frac{4}{5} y - 3[/tex]

Step-by-step explanation:

⅕y - ⅗y + 5 - ⅖y - 8

-0.8y-3

Answer: About 7.3 units

Step-by-step explanation: I got it right

The length of the segment GH is given by the distance D = 7.3 units

The distance of a line between 2 points is always positive and given by the formula

Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )

The distance between A and B is D , and the distance D is

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

Given data ,

Let the first point be G ( -9 , -4 )

Let the second point be H ( -2 , -6 )

Let the length of the segment GH = D

Now , distance between G and H is D , and the distance D is

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

On simplifying , we get

D = √ ( -9 - ( - 2 ) )² + ( -4 - ( -6 ) )²

D = √ ( -7 )² + ( 2 )²

On further simplification , we get

D = √ ( 49 + 4 )

D = √53

D = 7.28 ≈ 7.3 units

Hence , the distance is 7.3 units

Given:

The endpoints of line segment CD are C(-2,0) and D(4,9).

To find:

The midpoint of CD.

Solution:

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Using the midpoint formula, the midpoint of CD is

[tex]Midpoint=\left(\dfrac{-2+4}{2},\dfrac{0+9}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{2}{2},\dfrac{9}{2}\right)[/tex]

[tex]Midpoint=\left(1,4.5\right)[/tex]

Therefore, the midpoint of the line segment CD is (1,4.5).

Answer:

(13x * 10^53) + 10.

Step-by-step explanation:

To simplify the expression "13x 10^53--10" and write it using only positive exponents, we can follow these steps:

Step 1: Remove the double negative signs by converting them to positive signs:

13x 10^53 + 10

Step 2: Rewrite the expression by moving the term with a positive exponent to the denominator:

13x / (10^-53) + 10

Step 3: To simplify the denominator, we can rewrite 10^-53 as (1/10^53):

13x / (1/10^53) + 10

Step 4: Simplify the division of a fraction by multiplying by its reciprocal:

13x * (10^53/1) + 10

Step 5: Multiply 13x by 10^53:

(13x * 10^53) + 10

The simplified expression, written using only positive exponents, is (13x * 10^53) + 1
