Write the standard form of the equation of the circle with the center (0,2) that passes through (7,3)
Answer:
x²+y²-4y-46=0
Step-by-step explanation:
the equation of a circle is in the form (x - a)² + (y - b)² = r², where (a,b) is the center of the circle
the equation is (x - 0)² + (y - 2)² = r², where r is the radius. But r is the distance from (0,2) to (7,3)
the distance from two points is given by r² = (x₁ -x₂)² + (y₁ - y₂)²
r²= (0 - 7)² + (2 - 3)²
r² = 49 + 1 = 50
hence the equation is
(x)² + (y - 2)² = 50
x²+y²-4y+4 = 50
x²+y²-4y-46= 0
A rock is dropped from a bridge 320 feet above the river. The pathway that the rock takes can be modeled by the equation h= -16t2+320. How long will it take the rock to reach the river?
Answer:
288
Step-by-step explanation:
Answer: 4.47 seconds.
Step-by-step explanation:
Hi, the rock will reach the river when the height (h) is 0.
So, replacing in the equation given:
h= -16t2+320
Where t is the time
0= -16t2+320
Solving for t
-320 = -16t2
-320/-16 =t2
20 = t2
√20 =t
4.47 = t
Assuming that t is the time in seconds, the rock will reach the river after 4.47 seconds.

Please select the best answer from the choices provided
A
B
C
D
Answer:
Option C will have greatest number of permutations.
Step-by-step explanation:
A.
The number of license plates with 4 letters followed by 3 numbers, where letters and digits cannot be repeated.
We have total 26 letters (A_Z) and the letters can't be repeated. So we have 26 letter options for 1st letter
25 letters options for 2nd letter
24 letter options for 3rd letter
23 letter options for 4th letter.
So total options for 4 letters 26*25*24*23 = 358800
Now, 3 numbers are required. We have total 10 numbers (0-9)
10 number options for 1st number
9 number options for 2nd number
8 number options for 3rd number
Total options for 3 numbers= 10*9*8 = 720
total options for 4 letters and 3 numbers will be: 358800 * 720 = 258,336,000
B.
The number of license plates with 3 letters followed by 4 numbers, where letters and digits cannot be repeated.
We have total 26 letters (A_Z) and the letters can't be repeated. So we have 26 letter options for 1st letter
25 letters options for 2nd letter
24 letter options for 3rd letter
So total options for 3 letters= 26*25*24 = 15600
Now, 4 numbers are required. We have total 10 numbers (0-9)
10 number options for 1st number
9 number options for 2nd number
8 number options for 3rd number
7 number options for 4th number
Total options for 4 numbers = 10*9*8*7 = 5040
total options for 4 letters and 3 numbers will be: 15600 * 5040 = 78,624,000
C. The number of license plates with 4 letters followed by 3 numbers, where letters and digits can be repeated.
Now, the letters and digits can be repeated. So we have 26 options for each 4 letters and 10 options for each 3 numbers
26*26*26*26 *10*10*10 = 456,976 * 10,00 = 456,976,000
total options for 4 letters and 3 numbers will be: 456,976,000
D.
The number of license plates with 3 letters followed by 4 numbers, where letters and digits can be repeated.
Now, the letters and digits can be repeated. So we have 26 options for each 3 letters and 10 options for each 4 numbers
26*26*26 *10*10*10*10 = 17,576 * 10,000 = 175,760,000
total options for 3 letters and 4 numbers will be: 175,760,000
So, Option C will have greatest number of permutations.

Question:
A ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour. Which type of functions best models this situation?
A) exponential
B) linear
C) quadratic
D) radical
Answer & Step-by-step explanation:
It is given that a ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour.
If a function has constant rate of change, then the it is a linear function.
It the given case the rate of change is constant so linear function best model this situation.
The slope intercept form of linear function is
f(x)=mx+b ... (1)
where, m is slope and b is y-intercept or initial value.
Ski resort has 18 inches of snow on the ground it means initial value is 18.
The snow is falling at a rate of 4 inches per hour. So, m=4.
Substitute m=4 and b=18 in equation (1).
f(x)=4x+18
Therefore Linear decreasing function best model this situation and the required function is f(x)=4x+18.

Use the following information to find the test statistic of the sample used to test the claim that FICO credit scores are greater than 675. n = 50, = 719, s = 92
t = 32.437
t = –32.437
t = –3.382
t = 3.382
Answer:
t = –3.382
Step-by-step explanation:
Claim: FICO credit scores are greater than 675
Thus, x = 675
We are given:
Sample size = n = 50
Sample Mean = u = 719
Sample Standard deviation = s = 92
The formula to find the t-statistic is:
[tex]t=\frac{x-u}{\frac{s}{\sqrt{n} } }[/tex]
Using the above values, we get:
[tex]t=\frac{675-719}{\frac{92}{\sqrt{50} } }\\\\ t=-3.382[/tex]
Thus, the value of test statistic is -3.382. So 3rd option gives the correct answer.

Which angle is congruent to angle 1?
The angle that is congruent to angle 1 is angle 4 (m∠ 4).
What is congruent angle?
Congruent angles are angles that have the same measure in degrees or radians. So, if two angles are congruent, it means that they are equal in size.
From the diagram of the parallel lines, the angle that is all congruent to angle 1 include;
m∠ 1 = m∠ 4 (vertically opposite angles are equal)
m∠ 2 = m∠ 5 (vertically opposite angles)
m∠ 3 = m∠ 6 (vertically opposite angles)
So m∠ 1 = m∠ 4
Thus, the angle that is congruent to angle 1 is angle 4.

10x - 4 = +(8x + 14)
Simplify brackets
10x - 4 = 8x + 14
Add 4 to both sides
10x = 8x + 14 + 4
Simplify 8x + 14 + 4 to 8x + 18
10x = 8x + 18
Subtract 8x from both sides
10x - 8x = 18
Simplify 10x - 8x to 2x
2x = 18
Divide both sides by 2
x = 18/2
Simplify 18/2 to 9
x = 9
10x - 4 = 8x + 14
Step 1: Combine like terms
x's go with x's (10x and 8x). To do this subtract 8x to both sides
(10x - 8x) - 4 = (8x-8x) + 14
2x - 4 = 14
Normal numbers go with normal numbers (-4 and 14). To do this add 4 to both sides
2x + (-4 + 4) = 14 + 4
2x = 18
Step 2: Isolate x by dividing 2 to both sides
2x/2 = 18/2
x = 9

B. [tex]m\angle CAD=\frac{m\widehat {CD}-m\widehat {GE}}{2}[/tex].
Step-by-step explanation:
We have been given an image of a circle. We are asked to find the measure of angle CAD.
We can see that angle CAD is formed by two intersecting secants outside the circle.
Intersecting secants theorem states that when two secants intersects outside a circle, then the measure of angle formed by secants is half the difference of intercepted arcs.
[tex]m\angle CAD=\frac{\text{Larger arc-Smaller arc}}{2}[/tex]
[tex]m\angle CAD=\frac{m\widehat {CD}-m\widehat {GE}}{2}[/tex]
Therefore, option B is the correct choice.
