Answer:
(x+10) ^2 + (y-6)^2 = 64
Step-by-step explanation:
The equation of a circle can be written as
(x-h) ^2 + (y-k)^2 = r^2 where( (h,k) is the center and r is the radius
(x- -10) ^2 + (y-6)^2 = 8^2
(x+10) ^2 + (y-6)^2 = 64
what’s the answer to this ?
Answer: 12.73 cm
Step-by-step explanation:
The clock will move in a circular motion
The radius if the circle is 7.6 cm
So circumference= 2πr
= 2×22/7×7.6
=47.75 cm
Degree covered in 16 minutes=
360/60×16
= 96°
Now, since distance covered in 1° =
47.75/360 = 0.133
Distance covered in 96° =
47.75/360×96 = 12.73 cm ( approx.)
A car’s speed before a sudden stop can be estimated by the formula
S = √(30gk) , where
S = speed of the car in mph,
g = drag factor, and
k = length of skid mark in feet.
The drag factor during a recent crash was 1. What was the approximate speed of the car if it created skid marks 30 feet long?
a. 30 mph
b. 45 mph
c. 60 mph
d. 90 mph
Answer:
S = 30 mph
Step-by-step explanation:
A car’s speed before a sudden stop can be estimated by the formula :
[tex]S=\sqrt{30gk}[/tex]
Here,
S = speed of the car in mph,
g = drag factor, and
k = length of skid mark in feet
If drag factor is 1, k = 30 feet
So,
[tex]S=\sqrt{30\times 1\times 30}\\\\S=30\ mph[/tex]
Therefore, the correct option is (a) 30 mph.

If a credit card holder has a low APR. The minimum monthly payments will be?
A. higher
B. lower
C. unchanged
D. fluctuating
Answer:
Option B, the minimum monthly payments will be LOWER
Step-by-step explanation:
We can proof this by using hypothetical scenario below:
John has $1,500 with APR of 10% payable in 48 month equal instalment
Timmy has $1,500 with APR of 8% payable in 48 month equal instalment
Let us calculate monthly payment in each case
=pmt(rate,nper,-pv,fv)
rate is the monthly rate which APR/12
nper is 48
pv is the balance on the card which is $1,500
fv is the total monthly repayment which is unknown
John monthly payment=pmt(10%/12,48,-1500,0)=$38.04
Timmy monthly payment=pmt(8%/12,48,-1500,0)=$ 36.62
Since Timmy with a lower APR has a lower monthly payment, option B is correct
Susie leases a $13,000 car for three years. The estimated resell value at the end of the lease term is $7,683. The interest rate is 5.1%. Susie will pay on her lease monthly. What is the depreciation fee?
a) $43.95
b) $147.69
c) $249.53
d) $7,683.00
Answer:
The depreciation fee is the difference between the initial value of the car and its estimated resell value at the end of the lease term. In this case, the depreciation fee is $13,000 - $7,683 = $5,317.
To calculate the monthly payment on the lease, you would need to know the length of the lease in months, the interest rate, and the depreciation fee. You can then use the following formula to calculate the monthly payment:
Monthly payment = (Interest rate / 12) x (Initial value - Resell value) / Length of lease in months
For example, if the length of the lease is 36 months, the monthly payment would be:
Monthly payment = (5.1% / 12) x ($13,000 - $7,683) / 36 months = $114.78
Keep in mind that this is just an example calculation and the actual monthly payment on Susie's lease may be different depending on the specific terms of the lease agreement.

AB have a 90° angle with BC, so the angles ABD + CBD = 90
(7x - 9)° + 4x° = 90°
7x + 4x = 90 + 9
11x = 99
x = 99/11
x = 9
So the angles are:
7x - 9 -> 7.9 - 9 = 54°
4.9 = 36°
Answer:
m<CBD equals 54
Step-by-step explanation:
Since that is a right angle do (7x-9)+(4x)=90
=11x-9=90
=11x=99
x=9
CBD=7x-9
7(9)-9=54

What would happen if someone sarhpled a basketball team to find the
average height of a school's student body?
Answer:
Basketball players are normally taller so it would not be accurate
Answer: It wouldn't be valid or reliable because the basketball team is not indicitive of the entire student body. Additionally, sampling just the basketball team is not random nor is it likely a large enough sample size (unless it is a tiny school).

It took John 16 minutes to cook 8 eggs. How long would it take to cook 15 such eggs?
Answer:
30 minutes
Step-by-step explanation:
First, you need to find the amount of time it takes to cook one egg. To do this, you do 16/8 to get 2 minutes per egg. Then, since you need to cook 15 eggs, you do 15 times 2 to find the total amount of time to cook. You should get 30.
Look at Attachment, giving a lot of points for the answer to questions.
Answer:
see below
Step-by-step explanation:
1.
m = (y2-y1)/(x2-x1)
= (90-80)/(0-1)
= 10/-1
=-10
The slope is -10 ft/s
This means the height decreases 10 ft for every second that passes
This is not proportional because it has to go through the point (0,0)
4.
m = (y2-y1)/(x2-x1)
= (1000-0)/(3-0)
= 1000/3
=1000/3
The slope is $1000/3
This means the 1000 dollars is sold every 3 days
This is proportional because it goes through the point (0,0) and has a constant slope
Step-by-step explanation:
Let 'm' be slope
HAWK DIVING TOWARDS PREY:
m = (y2 - y1) / (x2 - x1)
= (90 - 80) / (0 - 1)
= 10 /- 1
= - 10
This is not proportional because it doesn't to go through the point (0, 0)
BOOK SALES:
m = (y2 - y1) / (x2 - x1)
= (1000 - 0) / (3 - 0)
= 1000/3
This is proportional because it goes through the point (0, 0)
Hope this helps!
Dogs in the GoodDog Obedience School win a blue ribbon for learning how to sit, a green ribbon for learning how to roll over, and a white ribbon for learning how to stay. There are 100 dogs in the school.
62 have blue ribbons, 55 have green ribbons, and 63 have white ribbons.
32 have a blue ribbon and a green ribbon 31 have a green ribbon and a white ribbon; 38 have a blue ribbon and a white ribbon.
16 have all three ribbons.
How many dogs have not learned any tricks?
Answer:
5
Step-by-step explanation:
The 32 that have blue and green ribbons include the 16 that have all three, so there are only 32 -16 = 16 that have only blue and green ribbons.
The 31 that have green and white ribbons likewise include the 16 with all three, so there are only 31 -16 = 15 that have only green and white ribbons.
The 38 that have blue and white ribbons include the 16 with all three, so there are only 38 -16 = 22 that have only green and white ribbons.
__
If we add the numbers of blue, green, and white ribbons, we are counting twice the numbers that have 2 ribbons, and 3 times the numbers that have 3 ribbons. We want to count each kind of ribbon-holder only once. Hence the number of individual dogs with any number of ribbons is only ...
62 +55 +63 -(16 +15 +22) -2(16) = 95
Of the 100 dogs, 95 have ribbons, so 5 dogs have not learned any tricks.
Equation 1: -4x + y = 6

Which variable is easiest to solve for?
A.The easiest to solve for is x in the first equation.
B.The easiest to solve for is y in the first equation.
C.The easiest to solve for is x in the second equation.
D.The easiest to solve for is y in the second equation.
Answer:
BStep-by-step explanation:
y in equation 1, since you just
-4x + y = 6
add 4x to both sides to get
y = 4x + 6
while for the rest of the variables in both equations, you need at least two steps
Thus, the answer is B
Answer:
B. The easiest to solve for is Y in the first equation.
Step-by-step explanation:
Since the y has no coefficient in both equations, we look at the steps we take to solve. Equation 2 has to make you multiply negative one by both sides to make y positive, and THEN you would have to subtract 5x from both sides. However, with the first equation, all we need to do to solve for Y is add 4x to both sides. The answer? B. The easiest to solve for is Y in the first equation.
