Point B is a point of tangency. Find the radius r of ⊙C.
Since Point B is a point of tangency, there is a right angle being created on the edge of that circle.
This means that the Pythagorean Theorem can be applied to solve for r.
[tex]a^2+b^2=c^2[/tex]
[tex]r^2+24^2=(16+r)^2[/tex]
*A common mistake here is distributing the square to both 16 and r, whereas you should be multiplying 16+r by itself (FOIL).*
[tex]r^2+576=r^2+32r+256[/tex]
The [tex]r^2[/tex]s cancel.
[tex]32r+256=576[/tex]
[tex]32r=320[/tex]
[tex]r=10[/tex]
The radius r of Circle C is 10.
Hope this helps!

For what values of x is the rational expression below undefined x-4/3x^2-65
parallel lines p and q are cut by two non parallel lines m and n as shown in the figure the value of x is ? degrees and the value of y is ? degrees
Answer:
Step-by-step explanation:
x+102+115+(180-115)=360
x+282=360
x=78 degrees
y=115 degrees
Answer:
x = 78
y= 115
Step-by-step explanation:
On the angle where p and m meet, we have congruent angles that both equal 102 degrees. The adjacent angles will add up to 180 degrees on a line. So, to find the missing angle, do this:
180-102 = 78 degrees
x is equal to the top right angle where p meets m as they are congruent.
x = 78
You can find y by realizing that the given angle on q meets n are congruent angles. If this angle equals 115 degrees, then y must also equal 115 degrees.
If a car has tires with a radius of 1.5 ft and the tires are spinning at 840 rpm (revolutions per
minute), how fast is the car traveling in mph?
[There are 5280 feet in 1 mile) Round your final answer to 2 decimal places.
Answer:
89·98 mph
Step-by-step explanation:
First, we get the circumference of the tires:
Circumference = [tex]\pi[/tex] × (radius × 2)
Circumference = 3.142 × (1·5 × 2)
Circumference = 3·142 × 3
Circumference = 9·426 ft
The circumference of the tire is equal to one round.
1 round = 9·426 ft
840 rounds = ?
We cross multiply to get the length that the tires would cover in a minute
= 840 × 9·426
1
1 minute = 7917·84 ft
60 minutes = ?
60 × 7917·84
1
= 475070·4 ft
5280 feet = 1 mile
475070·4 feet = ?
475070·4 × 1
5280
475070·4 ÷ 5280 = speed of the car in mph
89·97545
Round this off to 2 decimal places...
= 89·98 mph

Assume that the Poisson distribution applies and that the mean number of hurricanes in a certain area is 5.1 per year.
a. Find the probability that, in a year, there will be 4 hurricanes.
b. In a 45-year period, how many years are expected to have 4 hurricanes?
c. How does the result from part (b) compare to a recent period of 45 years in which 7 years had 4 hurricanes? Does the Poisson
distribution work well here?
a. The probability is 0.172
(Round to three decimal places as needed.)
b. The expected number of years with 4 hurricanes is 3.62
(Round to one decimal place as needed.)
Answer:
a) 0.172 probability that, in a year, there will be 4 hurricanes.
b) The expected number of years with 4 hurricanes is 7.7.
c) 7 years is close to the expected value of 7.7, which means that the Poisson distribution works well here.
Step-by-step explanation:
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.
The mean number of hurricanes in a certain area is 5.1 per year.
This means that [tex]\mu = 5.1[/tex]
a. Find the probability that, in a year, there will be 4 hurricanes.
This is P(X = 4).
[tex]P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}[/tex]
[tex]P(X = 4) = \frac{e^{-5.1}*(5.1)^{4}}{(4)!} = 0.172[/tex]
0.172 probability that, in a year, there will be 4 hurricanes.
b. In a 45-year period, how many years are expected to have 4 hurricanes?
Each year, 0.172 probability of 4 hurricanes. So for 45 years, the mean is 45*0.172 = 7.7.
The expected number of years with 4 hurricanes is 7.7.
c. How does the result from part (b) compare to a recent period of 45 years in which 7 years had 4 hurricanes? Does the Poisson distribution work well here?
7 years is close to the expected value of 7.7, which means that the Poisson distribution works well here.
If f(x) = x + 9 and g(x) = 9x – 4,
which statement is true?
Click on the correct answer.
3 is not in the domain of fºg.
3 is in the domain of fºg.
The true statement is (b) 3 is in the domain of f º g.
How to determine the true statementThe functions are given as:
[tex]f(x) = \sqrt{x + 9[/tex]
g(x) = 9x - 4
The function f º g(x) is calculated using:
f º g(x) = f(x)* g(x)
This gives
[tex]f\ o\ g(x) = \sqrt{x + 9} *(9x - 4)[/tex]
Set the radicand greater to 0
[tex]x + 9 \ge 0[/tex]
Solve for x
[tex]x \ge - 9[/tex]
This means that the domain is greater than or equal to -9
Hence, the true statement is (b) 3 is in the domain of f º g.

At the beginning of the Occupation, the Nazis basically let the Jews go about their business. This all changes in October 1940. Measures are introduced one after the other. Civil servants must sign an official declaration stating whether they are Jewish or not. Just like in Germany earlier on, Jewish civil servants and teachers are fired from their jobs. At the beginning of 1941, all Jews in the Netherlands must register.

6. How many solutions does the given system have?
y = 3x - 1
6x - 2y = -2
A. one solution
B. two solutions
C. infinite solutions
D. no solution
Answer:
C. Infinite, I think.
Step-by-step explanation:
Because if you plug in y=3x-1 the equation would be: 6x-2(3x-1)=-2 and when you distribute the 2, the equation becomes: 6x-6x-2=-2. Then you do 6x-6x which =0 and then subtract another 2 and you get -2=-2
