sin^2α
Step-by-step explanation:
I will just pose x instead of alpha here to make things simpler
[tex]\tan ^2\left(x\right)\left(2\cos ^2\left(x\right)+\sin ^2\left(x\right)-1\right)\\\\[/tex]
we know that sin^2x = 1 - cos^2x so...
[tex]=\left(-1+1-\cos ^2\left(x\right)+2\cos ^2\left(x\right)\right)\tan ^2\left(x\right)[/tex]
[tex]=\cos ^2\left(x\right)\tan ^2\left(x\right)[/tex]
we can rewrite using trigonometric identities (tan = sin/cos)...
[tex]=\left(\frac{\sin \left(x\right)}{\cos \left(x\right)}\right)^2\cos ^2\left(x\right)\\= \sin ^2\left(x\right)[/tex]

6. The sum of the measures of the angles in any triangle is 180 degrees. In triangle ABC, angles A and B have the same measures, while angle C is 57 degrees larger than the other two angles. Find the measure of angle C. a. 41 degrees b. 98 degrees c. 82 degrees d. 139 degrees Answer:
Answers
Answer:
well, if we want to know the measure angle c. we need to know the other angles measures. We know that c. is 57 more than a. and b.
So, if the triangle is 180 degrees in total, than we need to subtract 57 frm 180 to get 123. Now we divide that by 2 because that is what the other 2 angles will measure. 123 divides by 2 is 61.5.
now we subtract 61.5 from 180 to get 118.5
now to subtract 61.5 again because the 2 angles are the same measure. 118.5-61.5 is 57. so it cant be any of the answers you provided if angle a and b are the same

A high school football team scored 39 points in the game last night, with a combination of touchdowns (6 points each), extra points (1 point each), and field goals (3 points each).
The team make 1 more extra point than field goals, represented by the equation e=f+1, where e is the number of extra points and f is the number of field points scored.
They also scored five times as many points on touchdowns as field goals, represented by the equation 6t=15f, where t is the number of touchdowns and f is the number of field goals scored.
Write a system of equations representing this situation and use it to complete the statement.
The team scored __ touchdowns, __ extra points, and __ field goals.

A football team needs to move the ball at least 10 yards forward from the original starting point in order to get a first down. Angel runs for 6 yards on the first play. On the second play, he is sacked for −9 yards. At least how many yards does his team need on the third play to get a first down?
Answers
Answer:
13 yards
Step-by-step explanation:
Required distance moved from original position should be ≥ 10 yards in other to get a first down.
Run on first play = 6 yards
Second play = - 9yards
The least number of yards needed on third play :
Let yard needed on third play = x
First play + second play + third play = 10
6 + (-9) + x = 10
6 - 9 + x = 10
-3 + x = 10
x = 10 + 3
x = 13 yards
At least 13 yards is needed on third playbto get a first down.
Show that x + y : x - y= 3 : 2
Answers
Answer:
x + y : x - y = (5/2+1/2) : (5/2-1/2)
x + y : x - y = 3 : 2
Therefore, x + y : x - y= 3 : 2 is proved.
Step-by-step explanation:
Given
x + y : x - y = 3 : 2
As
[tex]x + y = 3[/tex]
[tex]x - y = 2[/tex]
Solving to find x and y
[tex]\begin{bmatrix}x+y=3\\ x-y=2\end{bmatrix}[/tex]
[tex]x-y=2[/tex]
[tex]-[/tex]
[tex]\underline{x+y=3}[/tex]
[tex]-2y=-1[/tex]
[tex]\begin{bmatrix}x+y=3\\ -2y=-1\end{bmatrix}[/tex]
solve for y
[tex]-2y=-1[/tex]
Divide both sides by 2
[tex]\frac{-2y}{-2}=\frac{-1}{-2}[/tex]
[tex]y=\frac{1}{2}[/tex]
[tex]\mathrm{For\:}x+y=3\mathrm{\:plug\:in\:}y=\frac{1}{2}[/tex]
[tex]x+\frac{1}{2}=3[/tex]
[tex]x+\frac{1}{2}-\frac{1}{2}=3-\frac{1}{2}[/tex]
[tex]x=\frac{5}{2}[/tex]
so
[tex]x=\frac{5}{2},\:y=\frac{1}{2}[/tex]
Thus,
x + y : x - y = (5/2+1/2) : (5/2-1/2)
x + y : x - y = 3 : 2
Therefore, x + y : x - y= 3 : 2 is proved.
A cab company charges $2.75 per mile, plus an extra surcharge. Bernardo took a cab to the
airport, which was 8 miles from his home. His total fare came to $29.50. Let x represent the
number of miles and y represent the total cost of the cab ride.
a. What is the slope-intercept equation of the line that fits this information?
b. If a customer paid $35, how many miles did they travel in the cab?
Answers
Answer:
a) $7.50
b) 10 miles
Step-by-step explanation:
a)
y=mx+b
y=$29.50
x=8
m=$2.75
b=unknown
29.50=2.75(8)+b
29.50-22=22-22+b
7.50=b
Check:
2.75(8)+7.50=29.50
b)
y=$35
x=unknown
m=2.75
b=7.50
35-7.50=2.75x+7.50-7.50
27.5/2.75=2.75/2.75x
10=x

2) Compare the following functions to determine which has the greater rate of change. Function 1: y = 2x + 6 Function 2: 0 4 -2 2 Y ] == a
Answers
You did not clearly mention the second function. So, I am assuming you meant to say that the second function has the table values such as:
x y
0 4
-2 2
So, I am solving the question based on this information table of the 2nd function, which anyways will clear your concept.
Answer:
We conclude that the rate of change of a function '1' is greater than the rate of change of function '2'.
Step-by-step explanation:
Given the function 1
[tex]y = 2x + 6[/tex]
Comparing the function with the slope-intercept form of the line equation of a linear function
[tex]y=mx+b[/tex]where m is the rate of change or slope of the line
so
[tex]y = 2x + 6[/tex]
rate of change = m = 2
Now, given the function 2
x y
0 4
-2 2
Taking the slope of the two points in the table
(0 4), (-2, 2)
[tex]\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(0,\:4\right),\:\left(x_2,\:y_2\right)=\left(-2,\:2\right)[/tex]
[tex]m=\frac{2-4}{-2-0}[/tex]
[tex]m=1[/tex]
So, the rate of change or slope of the function 2 is: m = 1
Hence, we observe that:
Rate of change of function 1 = m = 2Rate of change of function 2 = m = 1As the rate of change of a function '1' is greater than the rate of change of function 2.
i.e.
m = 2 > m = 1
Therefore, we conclude that the rate of change of a function '1' is greater than the rate of change of function '2'.
