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]

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.

Evaluate ab - 0.5.b when a= 1 and b = 5
Answers
Answer:
2.5
Step-by-step explanation:
a=1 and b=5 so it would be 1 times 5 minus 0.5 time 5. to get this you must used PEMDAS and multiplication goes before subtraction. 1 times 5 is 5 and 0.5 times 5 is 2.5 so now you can subtract one from another which would give you your answer.

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

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, - 448Step-by-step explanation:
The terms are:
a₁, a₂, a₃, a₄Given:
a₁ = a₂ + 35a₃ = a₄ + 560Use the nth term formula:
a₂ = a₁ra₃ = a₁r²a₄ = a₁r³Substitute:
a₁ = a₁r + 35 ⇒ a₁(1 - r) = 35a₁r² = a₁r³ + 560 ⇒ a₁(1 - r)r² = 560Divide the second equation by the first:
r² = 560/35r² = 16r = √16r = ± 4Use the first equation to find the first term:
a₁( 1 ± 4) = 351. a₁ = 35/-3 = -35/32. a₁ = 35/5 = 7We have two sequences:
r = 4
-35/3, -140/3, - 560/3, -2240/3r = -4
