Answer:
sinA = 12/13, cosA = 5/13, tanA = 12/5
sinB = 5/13, cosB = 5/13, tanB = 5/12
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
Sin(A) = 12/13
Sin(B) = 5/13
Cos(A) = 5/13
Cos(B) = 12/13
Tan(A) = 12/5
Tan(B) = 5/12

If there is a boy to girl ratio of 3:4, how many girls are there if there
are 18 boys? Complete the table to determine the answer.
Boys
Girls
Answers
Answer:
24 Girls
Step-by-step explanation:
3/4 = 18/x
3*x = 18*4
3x=72
3x/3=72/3
x=24
Because the ratio of boys to girls is 3:4, for every 3 boys there are 4 girls. 3 goes into 18 6 times and because the number of boys has increased by 6x, all we need to do is multiply 4 by 6 which is 25

Suzy makes 20 dollars an hour at her job. Bill only makes 10 dollars an hour but he has a starting bonus of 20. When will Suzy and Bill make the same amount of money for the same number of hours worked? How much will they both earn at the same time?
Answers
Answer:
2 hours
Suzy would earn $40
Bill will earn $40
they will both earn $80
Step-by-step explanation:
The total amount suzy earns is a function of the total hours worked. Let t represent time
total income of suzy = $20t eqn 1
Bill's income = starting bonus + variable pay
= $20 + $10t
We are looking for when they would earn the same amount :
20t = $20 + $10t eqn 2
collect like terms and solve for t
10t = $20
t = 2 hours
Substitute for t in either eqn 1 or 2
20(2) = $40
Suzy would earn $40
Bill will earn $40
they will both earn $80

when a graph line is vertical, it indicates that the relation is?
Answers
Answer:
When a vertical line is placed across the plot of this relation, it intersects the graph more than once for some values of x. If a graph shows two or more intersections with a vertical line, then an input (x-coordinate) can have more than one output (y-coordinate), and y is not a function of x.

Answer:

Step-by-step explanation:
Given
The missing equations are:
[tex]7 / \frac{1}{4} =[/tex]
[tex]7 * 4 =[/tex]
Required
Make a generalization about the equations
First, we solve both equations.
(1)
[tex]7 / \frac{1}{4} =[/tex]
[tex]7 / \frac{1}{4} = 7 * 4[/tex]
[tex]7 / \frac{1}{4} = 28[/tex]
(2)
[tex]7 * 4 =[/tex]
[tex]7 * 4 = 28[/tex]
From the solutions to the above equations, we can see that both equations have the same end result;
i.e.
[tex]7 / \frac{1}{4} = 7 * 4 = 28[/tex]
Hence;
A generalization can be: "they have the same end results"

Answers
Answer:
8c2 - 4c - 12
Step-by-step explanation:
Answer:
8c^2-4c-12
Step-by-step explanation
So you have to multiply 4c into 2c and -3 first and then 4 into 2c and -3.
(4c+4)(2c-3)
4c X 2c is 8c^2
(4c+4)(2c-3)
4c X -3 is -12c
So for the 4c multiplying in you would get 8c^2 and -12c, but we still have to multiply in the 4
4 X 2c is 8c
(4c+4)(2c-3)
4 X -3 is -12
So then we would get 8c^2-12c+8c-12, however we can still combine the -12c and the 8c. Combining those would get -4c. So the final answer is 8c^2-4c-12

A marine biologist is researching the population density of dolphins. The marine biologist counts 175 dolphins within a radius of 2.5 miles of a half-circle off of Clearwater Beach.
What is the population density of the dolphins?
Use 3.14 for pi, and round to the nearest whole number.
Answers
Answer:
Density = 9 dolphins / mi^2 This is the result.
Step-by-step explanation:
Number of dolphins = 175
Radius = 2.5 mi
1. - Calculate the area
Area = pi* r^2
Area = 3.14*2.5^2
Area = 3.14*6.25
Area = 19.625 mi^2
2. - Calculate the density
density = dolphins/mi^2
- Substitution
density = 175 / 19.625
Result
density = 8.9 dolphins/mi^2
Rounding to the nearest whole number
Density = 9 dolphins / mi^2
Answer:
Area of half circle = 1/2 x π x r^2
= 1/2 x 3.14 x 2.5^2
= 9.8125 miles²
For the density divide the number of dolphins by the area:
Density =population/area= 175/9.8125 = 17.83 dolphins/mile²
the population density of the dolphins is 18dolphin/miles²
