Which graph represents an exponential function?
Answer:
the linear graph man
please why ask ezzy questions
what is the equation of the following graph?
Answer:
Step-by-step explanation:
When figuring out the graph of a sinusoidal, I keep in mind the acronym FPARHM:
F - function (sine or cosine)
P - period
A - amplitude
R - reflections
H - horizontal/phase shift
M - midline
Looking at the graph, we can figure out that the function is sine (since it intersects the origin at its midpoint, the period is [tex]\pi[/tex] (because it repeats every [tex]/pi[/tex] units in the x-direction, the amplitude is 2 (because the graph's extreme points are 2 units away from the midline in the y-direction, there are no reflections, no horizontal/phase shift, and the midline is [tex]y=0[/tex] (since the graph isn't shifted up or down in the y-direction.
Finally, knowing all these parts, we can piece together the equation of the sinusoidal graph. In general, the equations of sinusoidal graphs are in the form [tex]y=a\sin(bx+c)+d[/tex] where [tex]|a|[/tex] is the amplitude, [tex] \frac{2\pi}{|b|}[/tex] is the period, [tex] \frac{c}{b}[/tex] is the horizontal shift, and [tex]d[/tex] is the midline. Additionally, if [tex]a[/tex] is negative, the graph needs to be reflected over the x-axis and if [tex]b[/tex] is negative, the graph needs to be reflected over the y-axis. Knowing this, all we need to do is plug in the amplitude, period, phase shift, and midline to the equation. The equation is [tex]y=2\sin(2x)[/tex]

Given P(E or F) = 0.69, P(E) = 0.49, and P(E and F) = 0.06, what is P(F)?
Answer:
P(F) = 0.26
Step-by-step explanation:
Given:
P(E ∪ F) = 0.69P(E) = 0.49P(E ∩ F) = 0.06Using formula: P(A ∪ B) = P(A) + P(B) - P(A ∩ B)
⇒ P(E ∪ F) = P(E) + P(F) - P(E ∩ F)
⇒ 0.69 = 0.49 + P(F) - 0.06
⇒ 0.69 = 0.43 + P(F)
⇒ P(F) = 0.69 - 0.43
⇒ P(F) = 0.26

Darya is a real estate broker with a house listing. She estimates that this listing will cost her $2300 for various expenses. If Darya sells the house within 6 months, she will receive a commission of $20,000. If it takes longer than 6 months, the listing will expire, and she'll lose the $2300 she spent on expenses. She estimates the probability that she'll sell the house within 6 months is 80%. Determine Darya's expectation for this listing.
Using a discrete distribution, it is found that Darya's expectation for this listing is of $13,700.
What is the mean of a discrete distribution?The expected value of a discrete distribution is given by the sum of each outcome multiplied by it's respective probability.
In this problem, considering the situation described in the text, the distribution is given by:
P(X = 17,700) = 0.8.P(X = -2,300) = 0.2.Hence, her expectation is given by:
E(X) = 0.8 x 17,700 - 0.2 x 2,300 = $13,700.

Answer:
[tex]\dfrac{1}{102}[/tex]
Step-by-step explanation:
Average rate of change of function [tex]f(x)[/tex] over the interval [tex]a \leq x \leq b[/tex] is:
[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]
Given function:
[tex]f(x)=\dfrac{2x-2}{5x-6}[/tex]
Given interval [tex]0\leq x\leq 8[/tex] :
when [tex]x=0[/tex]:
[tex]f(0)=\dfrac{2(0)-2}{5(0)-6}=\dfrac13[/tex]
when [tex]x=8[/tex]:
[tex]f(8)=\dfrac{2(8)-2}{5(8)-6}=\dfrac{7}{17}[/tex]
Therefore, average rate of change:
[tex]\dfrac{f(8)-f(0)}{8-0}=\dfrac{\frac{7}{17}-\frac13}{8}=\dfrac{1}{102}[/tex]

The radius of a circle is 14 centimeters. What is the circle's circumference?
Hello!
To solve this exercise, we must use the formula below:
[tex]\mathrm{C=2\cdot\pi\cdot r}[/tex]
C = ?π = 3.14r = 14cmKnowing these values, let's replace them in the formula to obtain r:
[tex]\mathrm{C=2\cdot 3.14 \cdot 14}\\\mathrm{C=6.28 \cdot 14}\\\\\boxed{\mathrm{C=87.92}}[/tex]
So, the circle's circumference is 87.92cm.
Hope this helps!
Answer:
[tex]\boxed{\sf{87.92cm}}[/tex]Step-by-step explanation:
To solve this problem, you need to multiply the radius of a circle by the circumference formula.
Circumference formula:
[tex]\sf{C=2\pi r}[/tex]
[tex]\sf{C=2*\pi r}[/tex]
C=?
π= 3.14
r= 14
[tex]\sf{2*3.14*14}[/tex]
Solve.
[tex]\sf{2*3.14=6.28}[/tex]
[tex]\sf{6.28*14=\boxed{\sf{87.92}}[/tex]
Therefore, the correct answer is 87.92cm.I hope this helps you! Let me know if my answer is wrong or not.

A missionary used his plane to take an injured girl 855 kilometers to the hospital. If he flew at an average speed of 171 kilometers per hour, how long did it take to reach the hospital?
Step-by-step explanation:
171 km/h
travel distance = 855 km
855 / 171 = 5 hours
it took him 5 hours to fly the 855 km (theoretically to the hospital).
normally, with a plane, you can't land on or at a hospital. you would need a helicopter to be able to do that.
so, he could only fly to a nearby airport, and then travel from there to the hospital. but we have no information about that.
