Step-by-step explanation:
So first thing is to determine which trigonometric ratio we use here. Theta is adjacent to 5 and 8 is the hypotenuse, so we should be using Cosine.
So we set up the equation
cos θ = adj/hype
cos θ = 5/8
θ = [tex]cos^{-1} (5/8)[/tex]
θ=51.3178125...
θ=51°

SAS Similarity Theorem C. SSS Similarity Theorem D. Any of the above could be used to show that the triangles are similar.
Answers
Answer:
1) Please find attached the given plot and sketch of the points created with Microsoft Word
2) The correct option is;
A. AA Similarity Postulate
Step-by-step explanation:
1) Please find attached the given plot and sketch of the points created with Microsoft Word
2) The given parameters are;
The coordinates of the points are A(0, 0), B(1, 0), C(1, 2), D(2, 0) and E(2, 4)
Therefore, we have;
The length of segment AB = 1
The length of segment BC = 2
The length of segment AD = 2
The length of segment DE = 4
Therefore, we have;
∠ABC = ∠ADE = 90°
∠BAC = = artctan(2/1) = ∠DAE = artctan(4/2) = 63.435°
Therefore, ΔABC and ΔADE are similar by AA Similarity Postulate

point slope form is below. since you have the slope already, all you have to do is plug in the point for x1 and y1 and then the slope for m

You buy x pounds of cherries for $2.99/b. What is a function rule for the
amount of change C you receive from a $50 bill?
Answers
A. C = 2.99x - 50
B. C = 50 - 2.99x
C. C = 50x - 2.99
D. C = 2.99 - 50x
2.99x
That’s the money you owe for the cherries. That eliminates choices C and D.
50 - 2.99x
When x is zero you should get 50 dollars back, so that eliminates A. You get 50 dollars back minus the money that you owe for the cherries, so that's choice B.
B. C = 50 - 2.99x

1. A(x)=x^2+6x+13
2. A(x)=2x^2+8x+14
Answers
Step-by-step explanation:
These aren't a perfect square bec. 1 st and 3rd terms must be perfect square
A(X) = X^2+6X +13 be perfect square if 13 Changed to 9
= X ^2+6X +9
A(x)= 2X^2+8X +14 be perfect square
= 4X ^2+ 8X + 16
Reagan and Nathan are 40 miles apart on a bike trail when they start pedaling toward each other on their b bicycles. Reagan rides at a constant speed of 8 miles per hour, and Nathan rides a constant speed of 10 miles per hour. How long does it take until Reagan and Nathan meet?
Answers
Answer:
They meet in 2.22 hours.
Step-by-step explanation:
We can find the time at which Reagan and Nathan meet by equaling the time as follows:
[tex] v_{R} = \frac{x_{R}}{t} [/tex]
[tex] x_{R} = v_{R}t [/tex] (1)
[tex] v_{N} = \frac{x_{N}}{t} [/tex]
[tex] x_{N} = v_{N}t [/tex] (2)
Where R is for Reagan and N for Nathan.
Knowing that:
[tex] x_{R} + x_{N} = 40 mi [/tex]
By adding equations (1) and (2) we have:
[tex] x_{R} + x_{N} = v_{R}t + v_{N}t [/tex]
[tex] t = \frac{x_{R} + x_{N}}{|v_{R}| + |v_{N}|} = \frac{40 mi}{8 mi/h + 10 mi/h} = 2.22 h [/tex]
Therefore, they meet in 2.22 hours.
I hope it helps you!

Which is the graph of the linear inequality x – 2y > –6?
Answers
Answer:
uhhh d????
Step-by-step explanation:
Graph D represents the linear inequality x – 2y > –6.
The given inequality is x – 2y > –6.
We rearrange the inequality as y < (1/2)x + 3
Now we have the inequality in slope-intercept form, y < mx + b, where m is the slope (1/2) and b is the y-intercept (3).
To graph this inequality, you can start by plotting the y-intercept, which is the point (0, 3).
The slope of the graph is 1/2.
However, the inequality is y < (1/2)x + 3, which means the shaded region is below the line.
Hence, graph D represents the linear inequality x – 2y > –6.

In 2007, the population of Ecuador was estimated at
13.8 million, with an annual growth rate of 1.6%. If this
rate continues, estimate when the population will reach
15 million.
Answers
Answer:
In 2012 , the population will be 15 million
Step-by-step explanation:
We start by setting up an exponential equation that defines the increase
P(t) = I(1 + r)^t
P(t) represents the present population = 15 million
I is the population in 2007 which is 13.8 million
r is 1.6% = 0.016
t is what we want to calculate
15 million = 13.8 million (1 + 0.016)^t
15/13.8 = (1.016)^t
1.09 = (1.016)^t
ln 1.09 = t ln 1.016
t = ln 1.09/ln 1.016
t = 5.429 which is approximately 5
So in 2007 + 5 = 2012, the population will be 15 million

Kiran paid $54.00 for 3 tickets to go to a corn maze. At the same rate, what is the cost of 5 tickets to the maze? *
Answers
Answer:90
Step-by-step explanation:
Answer: $90
Step-by-step explanation:
You can set up a proportion.
$54 = 3 tickets
x = 5 tickets
To find x, multiply 54 and 5.
54 × 5 = 270
Then divide 270 by 3.
270 ÷ 3 = $90
Since we figured out x = $90, this means that it costs $90 for 5 tickets.
