When using the vertical line test the vertical line can only go through the graph ____ times for it to be a function.
Answer:
once
Step-by-step explanation:
The vertical line test shows how many outputs (y-value) there are for one input (x-value). There can only one output for each input because only one value should satisfy an equation that represents a function. If the vertical line goes through the graph twice, that shows there are two outputs for a single x-value. This would mean it is not a function.

On one night, a scientist needs to determine the distance she is away from the International Space Station. At the specific time she is determining this the space station distance they are both on the same line of longitude 77' E. Furthermore, she is on a latitude of 29° N and the space station is orbiting just above a latitude of 61.4°N. In short, the central angle between the two is 32.4°. If the Earth's radius is 3959 miles and the space station orbits 205 miles above the surface of the Earth, then how far is the scientist away from the space station?

A car dealer earns $100 a week plus 5.5% on all sales. If he sold $57,000 in cars this week, how much did he earn?
Pls show work if possible
5.5% in decimal form is .055
From this, we can multiply $57,000 by .055, getting $3,135. And since the car dealer gets an extra $100 this week, he gets a total of $3,235.
Answer:
3235
Step-by-step explanation:
100$ a week plus 3135 which is 5.5% if 57,000

Part (a)
Answer: 87------------------
Work Shown:
v = u + a*t
v = 7 + 10*8 ... plug in the given values
v = 7 + 80
v = 87
==================================================
Part (b)
Answer: 10------------------
Work Shown:
v = u + a*t
80 = 20 + 6*t .... plug in the given values
80-20 = 6t .... subtracting 20 from both sides
60 = 6t
6t = 60
t = 60/6 .... divide both sides by 6
t = 10

Step-by-step explanation:
An automobile manufacturer finds that 1 in every 2500 automobiles produced has a particular manufacturing defect. (a) Use a binomial distribution to find the probability of finding 4 cars with the defect in a random sample of 7000 cars. (b) The Poisson distribution can be used to approximate the binomial distribution for large values of n and small values of p. Repeat (a) using a Poisson distribution and compare the results.
Answer:
a) 0.1558 = 15.58% probability of finding 4 cars with the defect in a random sample of 7000 cars.
b) 0.1557 = 15.57% probability of finding 4 cars with the defect in a random sample of 7000 cars. These probabilities are very close, which means that the approximation works.
Step-by-step explanation:
Binomial distribution:
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Poisson distribution:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
In which
x is the number of sucesses
e = 2.71828 is the Euler number
[tex]\mu[/tex] is the mean in the given interval.
To use the Poisson approximation for the binomial, we have that:
[tex]\mu = np[/tex]
1 in every 2500 automobiles produced has a particular manufacturing defect.
This means that [tex]p = \frac{1}{2500} = 0.0004[/tex]
a) Use a binomial distribution to find the probability of finding 4 cars with the defect in a random sample of 7000 cars.
This is [tex]P(X = 4)[/tex] when [tex]n = 7000[/tex]. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 4) = C_{7000,4}.(0.0004)^{4}.(0.9996)^{6996} = 0.1558[/tex]
0.1558 = 15.58% probability of finding 4 cars with the defect in a random sample of 7000 cars.
(b) The Poisson distribution can be used to approximate the binomial distribution for large values of n and small values of p.
Using the approximation:
[tex]\mu = np = 7000*0.0004 = 2.8[/tex]. So
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 4) = \frac{e^{-2.8}*(2.8)^{4}}{(4)!} = 0.1557[/tex]
0.1557 = 15.57% probability of finding 4 cars with the defect in a random sample of 7000 cars. These probabilities are very close, which means that the approximation works.

A bank is offering 3.5% simple interest on a savings account. If you deposit
$7,500, how much interest will you earn in 2 years?
Answer: $525
Step-by-step explanation:
The formula for Simple interest is calculated as PRT where
P = Principal = $7500
R = Rate = 3.5%
T = Time = 2 years
Interest = PRT
= 7500 × 3.5% × 2
= 7500 × 0.035 × 2
= $525

If <A and <B are supplementary angles and m<A = 4m<B, find m<A and m<B.
help !!! urgent!!!!!!
Answer:
m∠A = 144°, m∠B = 36°
Step-by-step explanation:
Supplementary angles are angles that add up to 180 degrees.
Substitute 4(m∠B) for m∠A.
4(m∠B) + m∠B = 180
5(m∠B) = 180
m∠B = 36°
Substitute 36 for m∠B.
4(36) = m∠A
m∠A = 144°

A rectangle is drawn so that the width is I feet
shorter than the length. The area of the rectangle
is 12 square feet. Find the length of the
rectangle,
Answer:
Length = 4 feet
Step-by-step explanation:
Let the length of a rectangle be x.
Width is 1 feet shorter than the length, b = x-1
The area of the rectangle is 12 sq feet.
The area of a rectangle is given by :
A = length × width
So,
[tex]x(x-1)=12\\\\x^2-x-12=0\\\\x^2-4x+3x-12=0\\\\x(x-4)+3(x-4)=0\\\\(x+3)(x-4)=0\\\\x=-3\ and \ x=4[/tex]
Neglecting the negative side, the length of the rectangle is equal to 4 feet.
