If the point (6, 9) is on the graph of an even function, what other point must also be on the graph?
Answer:
b/c it's an even function you know that f(x) = f(-x) too so whether you put in a positive X or a negative X you get the same answer so you know.. that (-6,9) is also on the graph of this function
Step-by-step explanation:
Given that the function is even and we know that (6, 9) is on its graph, we know that (-6, 9) must also be on the graph.
Even functions:
A function f(x) is even if:
f(x) = f(-x)
Now, we know that the point (6, 9) is on the graph of our function, this means that:
f(6) = 9
And because our function is even, we must have:
f(6) = f(-6) = 9
Then the point (-6, 9) must also be on the graph of the function.

The members of the Math team contributed a total of $9.10 for the party after their practice. Each member contributed the same amount of money in dimes only. How many members are in the team and how much money did everyone contribute? Give all possible answers.
Answer:
Number of possibilities
1) 91 members that contribute 1 dime each ($0.10)
2) 13 members that contribute 7 dimes each ($0.10 × 7 = $0.70)
3) 70 members that contribute 13 dimes each ($0.10 × 13 = $0.13)
Step-by-step explanation:
A dime = $0.10 in dollars
We are told that:
The total amount contributed = $9.10 for the party after their practice.
Each member contributed the same amount of money in dimes only.
Let the number of members be represented as: x
Number of possibilities
We find the factors of $9.1
= 1, 0.7, 0.13, 9.1
= 1 × 9.1
= 0.7 × 13
= 0.13 × 70
Hence:
1) $0.10 × x = $9.10
x = $9.10/$0.10
x = 91
Therefore, from the calculation above, there are 91 members and each of them contributed the same amount which was 1 dime ($0.10).
2)
7($0.10 )× x = $9.10
x = $9.10/$0.70
x = 13
Therefore, from the calculation above, there are 13 members that contribute 7 dimes each ($0.10 × 7 = $0.70)
3) 13($0.10) × x = $9.10
x = $9.10/$0.13
x = 70
Therefore, from the calculation above, there are 70 members that contribute 13 dimes each ($0.10 × 13 = $0.13)

O D. 3
Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 3, 4)
m = [tex]\frac{4-2}{-3-3}[/tex] = [tex]\frac{2}{-6}[/tex] = - [tex]\frac{1}{3}[/tex] → C
The slope of the line is -1/3 through the points(3, 2) and (-3, 4) which is correct option (C).
What is slope of line?Slope of line is defined as the angle of line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
What is graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
From the given graph we can pick the points which can tell us about the nature of the line that slope of line is negative.
Given,
Points of line is (3, 2) and (-3, 4)
Let
x₁ = 3, y₁ = 2
x₂ = -3, y₂ = 4
∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )
Substitute values in formula
m = (4 - 2)/(-3 - 3)
m = 2/(-6)
m = -1/3
Hence, the slope of the line is -1/3

Step-by-step explanation: First you find a using the equation they gave you. A=42.5. Then you plug it into the measures of the angles. But just by looking at the angles you can tell 2a would be the largest so you just plug a in there and you get your answer!
Yumiko has a rectangular-shaped patio. She wants to double the area of the patio by increasing the length and the width by the same amount.
The length is 14 and the width is 10.
a. Write a function, in factored form, to calculate the number of feet Yumiko would need to add to the length and width.
b. What are the dimensions of the patio, rounded to the nearest hundredth feet?
I am not very good with completing the square and would like to understand it better. Any help would be very appreciated!
Answer:
For a rectangle of length L and width W, the area is:
A = L*W
In this case, we start with:
L = 14ft
W = 10ft
Then the initial area is:
A = 14ft*10ft = 140ft^2
a) Now she wants to increase the same amount in each measure, then the new measures will be:
L = 14ft + x
W = 10ft + x
Now we want this new area to be twice the one that we got before, then the equation will be:
(14ft + x)*(10ft + x) = 2*140ft^2 = 280ft^2.
b) Let's solve the equation:
(14ft + x)*(10ft + x) = 280ft^2
First lets distribute the multiplication:
140ft + x*10ft + 14ft*x + x^2 = 280ft
Now let's group terms with the same power of x.
x^2 + (10ft + 14ft)*x + 140ft - 280ft = 0.
x^2 + 24ft*x - 140ft = 0.
Now we need to solve this quadratic equation, here we must use the Bhaskara equation for quadratic equations, and we will get two solutions for x.
[tex]x = \frac{-24ft +- \sqrt{(24ft)^2 - 4*140ft*1} }{2*1} = \frac{-24ft +- 33.7ft}{2}[/tex]
Then the two solutions are:
x = (-24ft - 33.7ft)/2 = -28.9 ft
This solution is negative, so it does not make sense and we can discard it.
x = (-24ft + 33.7ft)/2 = 4.85ft
This is positive, so we can use this.
Now we can find the new length and width:
L = 14ft + 4.85ft = 18.85ft
W = 10ft + 4.85ft = 14.85ft

2/7x + 1/5x = 34 x= what?
Answer:
70
Step-by-step explanation:
[tex]\frac{2}{7}x +\frac{1}{5}x=34[/tex]
We need to combine like terms but since they are fractions we first need to find a common denominator. The common multiple of 5 and 7 is 35 so we need to multiply 7 by 5 and 5 by 7, but we have to do the same to the numerator too.
[tex]\frac{2*5}{7*5} +\frac{1*7}{5*7}[/tex]
[tex]\frac{10}{35}x+\frac{7}{35} x=34[/tex]
Combine like terms
[tex]\frac{17}{35}x=34[/tex]
Divide 34 by [tex]\frac{17}{35}[/tex]
[tex]\frac{34}{1} *\frac{35}{17} =\frac{1190}{17} =70[/tex]

1-cos2a/1+cosa if 1/3 how much sin²a
Answer:
(1-cos2A) /(1+cos2A) =tan²A
Proof:
We know that,
cos(A+B) =cosA.cosB-sinA.sinB
=>cos2A=cos(A+A)
=>cos2A=cosA.cosA - sinA.sinA
=>cos2A=cos²A-sin²A
=>cos2A=(cos²A-sin²A)/(cos²A+sin²A
Since {cos²A+sin²A=1}
Divide the numerator & the denominator by (cos²A) to get,
cos2A = {(cos²A-sin²A) ÷cos²A} / {(cos²A+sin²A) ÷cos²A}
cos2A ={(1-tan²A)/(1+tan²A)}
Then,
1-cos2A = 1-[{(1–tan²A)/(1+tan²A)}]
1-cos2A =(1+tan²A-1+tan²A)/(1+tan²A)
1-cos2A=(2tan²A)/(1+tan²A)
And now.......
1+cos2A=1+[{(1-tan²A)/(1+tan²A)}]
1+cos2A={1+tan²A+1-tan²A}/{1+tan²A}
1+cos2A=2/(1+tan²A)
So now,
(1-cos2A)/(1+cos2A)= {2tan²A/(1+tan²A)}÷{2/(1+tan²A)}
={(2tan²A)(1+tan²A)}÷{2(1+tan²A)}
=tan²A

Solve the proportion 9/x = 18/5
Answer:
22.5
Step-by-step explanation:
Answer:
2.5
Step-by-step explanation:
Cross multiply:
9 * 5 = x * 18
Simplifying
9 * 5 = x * 18
Multiply 9 * 5
45 = x * 18
Reorder the terms for easier multiplication:
45 = 18x
Solving
45 = 18x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-18x' to each side of the equation.
45 + -18x = 18x + -18x
Combine like terms: 18x + -18x = 0
45 + -18x = 0
Add '-45' to each side of the equation.
45 + -45 + -18x = 0 + -45
Combine like terms: 45 + -45 = 0
0 + -18x = 0 + -45
-18x = 0 + -45
Combine like terms: 0 + -45 = -45
-18x = -45
Divide each side by '-18'.
x = 2.5
Simplifying
x = 2.5
