Need to find x, and measure of angle DEF

Answers

Answer:

x = 5

[tex] m\angle DEF = 90\degree [/tex]

Step-by-step explanation:

GE is the angle bisector of quadrilateral DEFG,

Thus, by angle bisector property:

9x°= (5x + 20)°

9x = 5x + 20

9x - 5x = 20

4x = 20

x = 20/4

x = 5

[tex] m\angle DEF = 9x\degree + (5x+20)\degree [/tex]

[tex] m\angle DEF = (14x+20)\degree [/tex]

[tex] m\angle DEF = (14\times 5+20)\degree [/tex]

[tex] m\angle DEF = (70+20)\degree [/tex]

[tex] m\angle DEF = 90\degree [/tex]

Find Four Numbers that form a geometric progression such that the second term is less than the first by 35, and the third term is greater than the fourth term by 560. (Note: there should be 3 different possible geometric sequences)

Answers

Answer:

-35/3, -140/3, - 560/3, -2240/37, -28, 112, - 448  

Step-by-step explanation:

The terms are:

a₁, a₂, a₃, a₄

Given:

a₁ = a₂ + 35a₃ = a₄ + 560

Use the nth term formula:

a₂ = a₁ra₃ = a₁r²a₄ = a₁r³

Substitute:

a₁ = a₁r + 35 ⇒ a₁(1 - r) = 35a₁r² = a₁r³ + 560  ⇒ a₁(1 - r)r² = 560

Divide the second equation by the first:

r² = 560/35r² = 16r = √16r = ± 4

Use the first equation to find the first term:

a₁( 1 ± 4) = 351. a₁ = 35/-3 = -35/32. a₁ = 35/5 = 7

We have two sequences:

r = 4

-35/3, -140/3, - 560/3, -2240/3

r = -4

What are the domain and range of g ( x ) =
-1/4( x - 17)2 + 61?

Answers

Answer:

Find the domain by finding where the function is defined. The range is the set of values that correspond with the domain.

Domain: (−∞,∞),{x|x∈R}

Range: (−∞,∞),{y|y∈R}

Step-by-step explanation:

Step-by-step explanation:

step 1. I assume g(x) = -(1/4)(x - 17)^2 + 61

step 2. domain is all the possible x's. all x's are permissible

step 3. domain: "all x" written as ( inf, -inf )

step 4. range is all the possible y values. g(x) is a quadratic pointing downward. the vertex (17,61) is the highest included y value

step 5. range: [61, -inf).

A ladder needs to reach a second-story window that is 15 feet above the ground and make an angle with the ground of 71°. How far out from the building does the base of the ladder need to be positioned? Round your answer to the nearest tenth.


The base of the ladder needs to be ______ feet away from the wall.

Answers

Answer:

5.2 feet

Step-by-step explanation:

It helps if you can make a drawing.

You are looking for the adjacent side of the 71° angle in a right triangle and 15 is the opposite side of the angle.

Let x = the distance from the building to the base of the ladder

Tan 71 = 15/x

xtan71 = 15

x = 15/tan 71 = 5.2 feet

You purchase a t-shirt for $9.55 and a pair of jeans for 18.12 from Old Army at 7% sales tax.

How much change should you receive if you give the cashier two twenty-dollar bills?

Answers

Answer:

$10.39 is the change

Step-by-step explanation:

We start by calculating the total score

9.55 + 18.12 = 27.67

we now calculate the sales tax

This is 7% of the total

= 7% of 27.67

7/100 * 27.67

= $1.94

The total now comes;

1.94 + 27.67 = $29.61

The total was 2 * 20 = $40

The change was;

$40 - $29.61 = $10.39

Calculate the gradient of the line using rise/run method.

Answers

Given:

The graph of line.

To find:

The gradient of the line using rise/run method.

Solution:

We know that the gradient of a line is also known as slope.

[tex]Slope=\dfrac{Rise}{Run}[/tex]

Consider the two intercepts, then rise is distance between origin and y-intercept and run is the distance between origin and the x-intercept. But rise must be negative because the value of y decreased from 3 to 0.

[tex]Rise=-3[/tex]

[tex]Run=2[/tex]

Now,

[tex]Slope=\dfrac{Rise}{Run}[/tex]

[tex]Slope=\dfrac{-3}{2}[/tex]

The gradient of the line is [tex]-\dfrac{3}{2}[/tex].

Therefore, the correct option is C.

What is the main difference between different types of map projections This is a problem about a child pushing a stack of two blocks along a horizontal floor. The masses of the blocks, and the coefficients of friction between the two blocks and between the lower block and the floor will be given. In order to do the pushing, the child will only be touching one of the two blocks. The mass of the upper block in the stack is 0.760 kg . The mass of the lower block in the stack is 1.630 kg . The coefficients of friction between the two blocks are: static 0.790, and kinetic 0.660. The child's mother, who likes to encourage his experiments, has oiled a small strip of the horizontal floor so that it is very slick; the coefficient of kinetic friction between the oiled section of floor and the lower block is only 0.080 and the coefficient of static friction is insignificantly different. Before the pushing starts, here is a question about the vertical forces acting on the two blocks. Required:What is the vertical component of the contact force on the lower block by the floor?
