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°

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

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

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.

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.

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.

A. C = 2.99x - 50
B. C = 50 - 2.99x
C. C = 50x - 2.99
D. C = 2.99 - 50x

That’s the money you owe for the cherries. That eliminates choices C and D.
