if c and d vary inversely, and d=5/3 and c=5. write a function that models inverse variation and find d when c=10
9514 1404 393
Answer:
cd = 25/3d = 5/6Step-by-step explanation:
The inverse variation described can be either of ...
c = k/d
or
d = k/c
Either way, the equation can also be written as ...
cd = k
For the given values of c and d, the value of k is ...
(5)(5/3) = k = 25/3
So, the model can be written as ...
cd = 25/3
or
d = (25/3)/c
__
For c=10, the value of d is ...
d = (25/3)/10 = 25/30
d = 5/6

Answer:
B. 45
Step-by-step explanation:
we know the sum of both angles is 90 because of the small sqaure in the corner.
90 = 2x+20
70 = 2x
45 = x
Answer:
35
Step-by-step explanation:
Because of the box in the graph, you can tell that this is a 90-degree angle
2x means the next angle will be twice of the answer choice number
because the end product must be 70 the answer must be 35
35 x 2 = 70

10. The table shows the change in your hair length over a year.
January
February
August
September
December
Month
Change in hair
length (inches)
2
-1
3
4
3
a. What is the total change in your hair length at the end of the year?
b. Is your hair longer in January or December? Explain your reasoning.
c. When is your hair the longest? Explain your reasoning.
Answer:
3
December. total change in December is greater than change in January. 3 is greater than 2
August. the total change in hair growth is 4.
Step-by-step explanation:
total change in hair length = 2 - 1 + 3 - 4 + 3 = 3
My hair is longer in January .
total change in hair length in February = 2 -1 = 1
total change in hair length in August = 1 + 3 = 4
total change in hair length in September = 4 - 4 = 0
total change in hair length in December = 0 + 3 = 3
My hair is the longest in August because that is the month that has the highest change in hair length

Find the following trigonometric Fourier Series:
(a) Extend the definition of f(x) to make it an even function f*(x),
[tex]f^*(x)=\begin{cases}0&\text{if }-2\le x<-1\\1&\text{if }0\le x\le1\\0&\text{if }1<x\le2\end{cases}[/tex]
and we take f* to be periodic over an interval of length P = 4. We compute the coefficients of the cosine series:
[tex]a_n = \displaystyle\frac2P \int_{-2}^2 f^*(x)\cos\left(\frac{2n\pi}Px\right)\,\mathrm dx = \frac{2\sin\left(\frac{n\pi}2\right)}{n\pi}[/tex]
Note that a₀ = 1 (you can compute the integral again without the cosine, or just take the limit as n -> 0). For all other even integers n, the numerator vanishes, so we split off the odd case for n = 2k - 1 :
[tex]a_{2k-1} = \dfrac{2\sin\left(\frac{(2k-1)\pi}2\right)}{(2k-1)\pi}[/tex]
Then the cosine series of f(x) is
[tex]\displaystyle \frac{a_0}2 + \sum_{k=1}^\infty a_{2k-1}\cos\left(\frac{(2k-1)\pi}2x\right)[/tex]
(b) For the sine series, you instead extend f(x) to an odd function f*(x),
[tex]f^*(x)=\begin{cases}-1&\text{if }-2\le x\le-1\\x&\text{if }-1<x<1\\1&\text{if }1\le x\le2\end{cases}[/tex]
Again, P = 4, and the coefficient of the sine series are given by
[tex]b_n = \displaystyle\frac2P\int_{-2}^2f^*(x)\sin\left(\frac{2n\pi}Px\right)\,\mathrm dx[/tex]
which we can again split into the even/odd cases,
[tex]b_{2k} = -\dfrac1{k\pi}[/tex]
[tex]b_{2k-1} = \dfrac{4(-1)^{k+1}+2(2k-1)\pi}{(2k-1)^2\pi^2}[/tex]
So the sine series is
[tex]\displaystyle \sum_{k=1}^\infty\left(b_{2k}\sin\left(k\pi x\right) + b_{2k-1}\sin\left(\frac{(2k-1)\pi}2x\right)\right)[/tex]
I've attached plots of the extended versions of f(x) along with the corresponding series up to degree 4.

Q2) What are the rules for probability distributions ? I
Answer:
Probability Distributions
A listing of all the values the random variable can assume with their corresponding probabilities make a probability distribution.
A note about random variables. A random variable does not mean that the values can be anything (a random number). Random variables have a well defined set of outcomes and well defined probabilities for the occurrence of each outcome. The random refers to the fact that the outcomes happen by chance -- that is, you don't know which outcome will occur next.

Word problem will mark brainly
Answer:
A) Replace L with the length of the skid mark:
Speed = √(20(208))
Speed= √(4160)
Speed = 64.5 miles per hour
B) set the equation to the speed and solve for L:
47 = sqrt(20L)
Square both sides:
2209 = 20L
Divide both sides by 20:
L = 110.5 feet
The odds in favor of Frank McKinnis winning a hot dog eating contest are 2:7.
simple
a. Determine the probability that Frank will win the contest.
nas 0.216
b. Determine the probability that Frank will not win the contest.
a. The probability that Frank will win the contest is
b. The probability that Frank will not win the contest
Answer:
the probability of winning & not winning the contest is 2 ÷ 9 and 7 ÷ 9 respectively
Step-by-step explanation:
The computation is shown below
a. The probability of Frank win the contest is
= 2 ÷ 2 + 7
= 2 ÷ 9
b. The probability of Frank that not win the contest is
= 1 - 2 ÷ 9
= 7 ÷ 9
hence, the probability of winning & not winning the contest is 2 ÷ 9 and 7 ÷ 9 respectively
The same would be relevant

In the polyhedron above x=5 mm, y=9 mm, and z=4 mm. The volume of the polyhedron is _____ mm3. Round your answer to the tenths place.
Answer:
180 mm³
Step-by-step explanation:
The polyhedron is an oblique rectangular prism
Area of the oblique rectangular prism = base area * height
height = z = 4 mm
Base area = L*W
L = y = 9 mm
W = x = 5 mm
Base area = 9*5 = 45 mm²
Area of the oblique rectangular prism = 45*4 = 180 mm³

37
Please select the best answer from the choices provided
ОООО
Oo
Answer:
d. 12√37 / 37
Step-by-step explanation:
standard formula for the distance between a point (x₀,y₀) and a line ax+by+c=0 is |a*x₀ + b*y₀ + c| / √a²+b²
(x₀,y₀) : (-2 , 3)
ax+by+c=0 : 6x - y +3 = 0
x₀ = -2 y₀ = 3 a = 6 b = -1 c = 3
d = | 6*(-2) + (-1)*3 + 3 | / √6²+(-1)²
d = 12 / √37 = 12√37 / 37
Hey guys I don’t understand this one so can y’all please help me? :))))
Answer:
11) c = 16.1
12) c = 11.4
Step-by-step explanation:
11)
a² + b² = c²
8² + 14² = c²
64 + 196 = c²
c² = 260
[tex]\sqrt{c^2} =\sqrt{260}[/tex]
c = 16.1
12)
a² + b² = c²
7² + 9² = c²
49 + 81 = c²
c² = 130
[tex]\sqrt{c^2} =\sqrt{130}[/tex]
c = 11.4

what kind of angle does an acute triangle have
Answer:
An acute angle is an angle that measures less than 90 degrees. A triangle formed by all angles measuring less than 90˚ is also known as an acute triangle. For example, in an equilateral triangle, all three angles measure 60˚, making it an acute triangle.

What is the value of m in mn= 12?
A) m= 12-n
B) m = 14
C) m= 12n
D) m = 12 + n
Answer: There is no choice available for the answer.
Step-by-step explanation:
The question is asking for the value of m in terms of n, so we need to isolate m to one side.
Given
mn=12
Divide n on both sides
mn/n=12/n
m=12/n
