Lines b and c are parallel. What is the measure of <6?
m<6 = 45
m<6 = 54
m<6 = 117
m<6 = 126
Answers
Answer:
m<6 = 54
St,ep-by-step explanation:
Lines b and c are parallel.
13x +9 and 5x+9 are consecutive exterior angles.
Consecutive exterior angles are supplementary.
[tex]13x+9+5x+9= 180[/tex]
Now we solve for x. combine like terms
[tex]18x+18= 180[/tex]
Subtract 18 from both sides
[tex]18x=162[/tex]
Divide both sides by 18
x=9
So the value of x=9
angle 6 and 5x+9 are vertical opposite angles . they are equal
m<6= 5x+9
Plug in 9 for x
m<6= 5(9)+9=54
m<6 = 54
Answer:
m<6 = 54

1. How would you prove that circles are similar?
3.Find the center and the radius for the circle, given the equation:
x^2-14x+y^2+8y=16
Answers
we know that
All circles are similar. Figures can be proven similar if one, or more, similarity transformations (reflections, translations, rotations, dilations) can be found that map one figure onto another. In our attempt to prove all circles are similar, a translation and a scale factor (from a dilation) will be found to map one circle onto another

Answers
First you have to find the missing angle in the triangle
The angles in a triangle add to 180°
180 - 97 - 30 = 53
The angle we just found and angle x form a straight line meaning they add to 180°
180 - 53 = 127
The answer is 127°
Hope this helps!
X is part of a straight angle, which should add up to 180°.
So first we need to figure out what the other side of this straight angle is. Since the other side is inside the triangle, it should be easy.
All angles in any triangle always add up to exactly 180°. To figure out what the last angle is in the triangle, we just need to add the two existing angle measurements together and subtract the sum from 180.
97 + 30 = 127
180 - 127 = 53
So the last angle in the triangle is 53°.
Now, we can figure out the value of x. Since x is part of a 180° straight angle, and we know that half of said angle is 53°, we can find x by subtracting 53 from 180.
180 - 53 = 127
x = 127
Hope this helps :)

The sides of a rectangle are in a 3:4 ratio. What is the length of the shorter sides of the rectangle if it's perimeter is 42cm
Answers
Given a rectangle with sides in a 3:4 ratio and a perimeter of 42 cm, the length of the shortest side is 9 cm.
Explanation:We are given that the sides of the rectangle are in a 3:4 ratio and that the perimeter is 42 cm. The rectangular perimeter is calculated by the formula 2*(length + width). In this case, because the sides are in a 3:4 ratio, we can say 2*(3x + 4x) = 42, where 'x' represents the length of the shortest side.
Solve this equation, 2*(7x) = 42, we find that 'x' is 3. So the length of the shorter side, 3x, is 9 cm. Applying the same 3:4 ratio, the longer side, 4x, is 12 cm.

To find the length of the shorter side of a rectangle with sides in a 3:4 ratio and a perimeter of 42cm, we set up an equation using the ratio values as coefficients and the known perimeter. Solving this equation shows that a unit in the ratio equals 3cm and the shorter side is 9cm.
Explanation:In this mathematics problem, we are trying to find the length of the shorter side of a rectangle, knowing that the sides are in a 3:4 ratio and that the perimeter is 42cm. The perimeter of a rectangle can be found by using the equation [tex]P=2L+2W[/tex] (Perimeter equals twice the length plus twice the width).
If we represent the shorter side as 3x and longer side as 4x, we can establish the following equation based on the given perimeter:[tex]2*(3x)+2*(4x)=42c[/tex]m. Simplifying this equation gives 14x=42cm. Solving for 'x', we find x=3. Therefore, each unit in the ratio corresponds to 3cm, and the length of the shorter side, represented by 3x, is [tex]3*3=9[/tex]cm.

Answers
c(x) = 3x2 − 10x + 200
and
r(x)=−2x2 + 100x + 50
Profit is given by:
P(x)=r(x)-c(x)
P(x)=(−2x2 + 100x + 50)-(3x2 − 10x + 200)
P(x)=-5x^2+110x-150

where A is the monthly payment,
P is the current balance (4645),
r is the annual rate (.197),
n is the number of compoundings per year (12), and

A crowd of 50,000 fans is expected to attend the homecoming football game. if the typical vendor can serve 1,500 customers per hour and the game will last for four hours, how many vendors are needed to ensure that each fan can be served during the game? (round to the nearest whole number.) a) 9 b) 10 c) 8 d) 1
Answers
Since every hour, a vendor sells to 1500 customers, we multiply by hours, like this:
1500 * 4 = 6000.
Then we divide 50000/6000, and that would give us 8.33333333, and we round that to the next number which is 9, and that's the answer.
Answer: 9 vendors.
Hope this helped! c:
Using Multiplication, There are 9 vendors are needed to ensure that each fan can be served during the game.
What is Multiplication?Multiplication is to "increase a number by the number of times mentioned".
According to the question,
Number of fans expected to attend a football game = 50,000
Number of customer to be served = 1,500per hour
To find number of customer to be served for 50,000 fans
The game has to be last for 4 hours.
Formula : 1 vendor is to sell 1,500 customer per hour
4*1500 = 6000
A vendor has to sell 6000 customers in 4 hours.
In order to find the number of vendors have to sell 50,000 customers in 4 hours
Let 'x' be the number of vendors
To find the number of vendors only if we divide 50,000 by 6000
=[tex]\frac{50,000}{6000}[/tex] = 8.333 ≈ 9
Hence, there are 9 vendors are needed to ensure that each fan can be served during the game.

What is cos (x)?
A) 48/58
B) 58/48
C) 26/58
D) 58/26
Answers
In order to solve for the Cos(x), you need to find the missing side. You can do that by finding the Sin(x) first and then the Cos of x or you can just use the Pythagorean theorem. I'm going to do the latter.
Formula
a^2 + b^2 = c^2
Givens
a = ???
b = 32
c = 58
Sub and solve
a^2 = ???
b^2 = 1024
c^2 = 3364
a^2 + 32^2 = 58^2
1024 + a^2 = 3364 Subtract 1024 from both sides.
a^2 = 3364 - 1024
a^2 = 2340 Take the square root of both sides.
sqrt(a^2) = sqrt(2340) Break a into its prime factors.
a = sqrt(2 * 2 * 5 * 3 * 3 * 13)
Rule
For every pair of equal factors, one can be brought outside the root sign and the other is discarded.
a = 2 * 3 * sqrt(5*13)
a = 6 sqrt(65)
The cos of an angle = opposite / hypotenuse.
Cos(x) = 6*sqrt(65) / 58 <<<<< This should be the answer

Which function has the greatest maximum y-value?
a. f(x)
b. g(x)
c. g(x) and h(x)
d. f(x) and h(x)
Answers
Given an arbitrary function '[tex]f(x)[/tex]' we find the point of slope 0 by taking its first derivative and equaling to 0 ('[tex] \frac{d}{dx}f(x)=0 [/tex]').
Lets, first, find the local extremes of the first function:
[tex]f(x)=cos(x)[/tex]
[tex] \frac{d}{dx} f(x)=\frac{d}{dx}cos(x)=-sin(x)=0[/tex]
[tex]x=sin^{-1} (0)=0[/tex]
So our first function has a maxima at '[tex]x=0[/tex]' or at '[tex]y=f(0)=cos(0)=1[/tex]'.
Now we get the extremes for the second function:
[tex]h(x)=2cos(x)+1[/tex]
[tex]\frac{d}{dx} h(x)=\frac{d}{dx}[2cos(x)+1]=-2sin(x)=0[/tex]
[tex]x=0[/tex]
So our second function has a maxima at '[tex]x=0[/tex]' or at '[tex]y=h(0)=2cos(0)+1=3[/tex]'.
Clearly, '[tex]h(0)=3\ \textgreater \ f(0)=1[/tex]', this means the second function '[tex]h(x)[/tex]' has the largest maxima -y value-.
Answer:
f(x) and h(x)
Step-by-step explanation:
f(x) and h(x) have the greatest maximum y-value because if you graph out all the equations you can determine by graph which ones have the greatest y-value. When you graph the equations you find that f(x) and h(x) both have a greatest y-value of 3! While g(x) has a greatest y-value of -2.
*Please note that it is looking for the greatest y-VALUE not the greatest y-INTERCEPT.

The hypotenuse of a right triangle is 5 m long. The longer leg is 1 m longer than the shorter leg. Find the side lengths of the triangle.
Answers
The Pythagorean theorem is used to determine the lengths of a right triangle's sides. When we know the hypotenuse length and the fact that one leg is 1m longer than the other, we can solve for the lengths to be approximately 3m and 4m.
Explanation:The subject of your question is related to the geometric concept of right triangles and the Pythagorean theorem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be written as: a² + b² = c².
In this problem, we know the hypotenuse = 5m and the longer leg is 1m longer than the shorter leg. Let's denote the shorter leg as 'x' m. Consequently, the longer leg is 'x+1' m. Applying the Pythagorean theorem, we get: (x)² + (x+1)² = 5².
Solving this equation, we find x~3m (shorter leg) and x+1~4m (longer leg). These are the lengths of the sides of your right triangle.
