Please help with this geometry problem and explain it step by step

Answers

Answer 1

Answer:

x = 26

Step-by-step explanation:

Angles ABC and CBD are supplementary, so they add up to 180.

(2x - 10) + (5x +8) = 180

7x - 2 = 180

7x = 182

x = 182/7 = 26

Wendy and Connor each deposit 8,300 into accounts that earn 3.5% interest for 25 years Wendy's account earns annual simple interest sand Connor's account earns an annual compound interest who will earn more interest of 25 years and how much interest they will earn

Answers

Answer:

Connor will earn more interest because he is getting compound interest.

Step-by-step explanation:

I have to assume in this case that the interest is 3.5% Per year:

Simple Interest = P(r + t)

{P = Principle, r = interest rate, t = time)

Wendy = $8,300 x (3.5% x 25)

Wendy = $7,262.50 (2 d.p)

Wendy = $8,300 + $7,262.50

Wendy = $15,562.50

Compound Interest = [tex]P (1 +r )^{t}[/tex]

{P = Principle, r = interest rate, t = time)

Connor = $8,300 x [tex](1 + 0.035)^{25}[/tex]

Connor = $19,614.93

Wendy's Interest = $15,562.50 - $8,300 = $7,262.50

Connor's interest = $ 19,614.93 - $8,300 = $11,314.93

Connor earned more interest by $4,052.43

A quadratic function y = f(x) is plotted on a graph and the vertex of the resulting
parabola is (-4,-6). What is the vertex of the function defined as
g(x) = f(x) + 3?

Answers

Answer:

(- 4, - 3 )

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

For

g(x) = f(x) + 3

This is the graph of f(x) shifted 3 units up

Given the vertex of f(x) = (- 4, - 6 ), then

vertex of g(x) = (- 4, - 6 + 3) = (- 4, - 3 )

A circular plate has a diameter of 9 inches. What is the area of the plate? Explain the steps you follow to get to your answer

Answers

Answer:

The area of the circular plate is: " 63.59 in² " .

______________________________________________________

Note:

______________________________________________

diameter, "d" = 9 in. (given).

radius, "r" = "d/ 2 " = "(9 inches) / 2 " = 4.5 in.

______________________________________________

Area of a circle, "A" :

A = * r² ;

in which: "A = Area of circle ("plate"); in units of "square inches"; or "in² " ;

" = 3.14 " {approximation we shall use} ;

"r = radius = 4.5 in." ;

________________________________________________________

Plug in our known values to solve for the area, "A" :

A = (3.14) * (4.5 in)² ;

A = (3.14) * (4.5)² * (in²) ;

A = (3.14) * (4.5) * (4.5) * (in²) ;

A = 63.585 in² ; round to: " 63.59 in² " .

Answers

Answer:

x=-6, y=0

Step-by-step explanation:

Use the 3x-9y=-18 equation and add 9y to both sides to have 3x on its own on the left side. Then, divide by 3 on both sides. Then you'll have x=-6+3y. Plus this back into the 5x+4y=-30 equation and you'll get 5(-6+3y)+4y=-30. Use the distributive property and you'll get -30+15y+4y=-30. Simplify and get -30+19y=-30, then add 30 to both sides and you'll get 19y=0. Divide by 19 on both sides and you'll get y=0. Now that we know y=0, plug that back into the 5x+4y=-30 equation, and you'll get 5x+4(0)=-30. Simplify and you'll get 5x=-30. Divide by 5 on both sides and you'll get x=-6.

How to determine the true statement?

When a figure is rotated, the side lengths and the angle measures of the figure remain unchanged.

This means that:

The figure RST is congruent to the figure OPQ.

The choice of option that supports the above highlight is

m<S = m<P

Hence, the true statement is (d) m<S = m<P
