Answer:
(x - 8)^2 + (y - 4)^2 = 16.
Step-by-step explanation:
The standard form can be written as:
(x - a)^2 + (y - b)^2 = r^2 where (a, b) is the center and r = the radius.
So here we have a = 8, b = 4 and r = 4.
(x - 8)^2 + (y - 4)^2 = 4^2
(x - 8)^2 + (y - 4)^2 = 16.
The function f(x) = –x2 − 2x + 15 is shown on the graph. What are the domain and range of the function? The domain is all real numbers. The range is {y|y < 16}. The domain is all real numbers. The range is {y|y ≤ 16}. The domain is {x|–5 < x < 3}. The range is {y|y < 16}. The domain is {x|–5 ≤ x ≤ 3}. The range is {y|y ≤ 16}.
Answer:
The domain is all real numbers. The range is {y|y ≤ 16}
Step-by-step explanation:
we have
[tex]f(x)=-x^{2}-2x+15[/tex]
This is a the equation of a vertical parabola open downward
The vertex is a maximum
The vertex is the point (-1,16)
see the attached figure
therefore
The domain of the function is all real numbers ----> interval (-∞,∞)
Te range of the function is
[tex]y\leq 16[/tex]
All real numbers less than or equal to 16 ----> interval (-∞,16]

When is a lower annual interest fee better than a low annual fee
Answer: a lower annual interest fee is better than a low annual fee if you expect to pay your balance in full during most months
Final answer:
A lower annual interest fee is generally better than a low annual fee when it leads to significant savings over time, especially with large amounts or long-term financial products. Interest rates dictate the overall cost of borrowing more than annual fees, particularly for longer terms or larger sums. However, for small, short-term borrowing, a low annual fee might be more beneficial.
Explanation:
When comparing a lower annual interest rate versus a low annual fee, it is essential to consider the specific financial situation and the amount of money involved. As a general rule, a lower interest rate is beneficial when it leads to significant savings on the overall interest paid throughout the loan or credit product term. This is often the case for larger amounts or longer terms where the interest accumulates considerably over time.
For example, financial investors who choose a Certificate of Deposit (CD) earn a higher interest rate compared to savings accounts, as they agree to leave the money deposited for a fixed period, forgoing liquidity. However, if interest rates rise after a loan is made, the existing loan with the lower interest rates becomes less attractive. On the other hand, if the economy experiences a fall in interest rates, the value of the loan with the previously fixed lower rate increases.
Therefore, while a low annual fee can seem attractive, it's the annual interest that ultimately has a more significant impact on the cost of borrowing, especially over longer periods or with larger sums of money. Conversely, for small short-term loans or when the outstanding balance is frequently paid off, a low annual fee might be more advantageous than a lower interest rate, as the interest charges could be minimal.

Step by step If C(m)=0.50m + 30 represents the cost of renting a car, how many miles were driven if the cost is $130
Answer:
200 miles were driven
Step-by-step explanation:
We know that [tex]C (m) = 0.50m + 30[/tex] represents the cost of renting a car
Where m represents the number of miles driven
If we know that the cost was $ 130 then we can equal C(m) to 130 and solve for m.
[tex]C(m) =0.50m + 30=130[/tex]
[tex]0.50m + 30=130[/tex]
[tex]0.50m=130-30[/tex]
[tex]0.50m=100[/tex]

10 In(100x) – 3 = 117
To solve the equation 10 ln(100x) - 3 = 117, first isolate the ln(100x) by adding 3 to both sides and then divide by 10. Exponentiate both sides with base e to remove the ln, and finally divide by 100 to solve for x.
Explanation:Solve the logarithmic equationWe are given the equation 10 ln(100x) – 3 = 117. To solve for x, follow these steps:
Add 3 to both sides of the equation to isolate the logarithmic expression.
10 ln(100x) = 120
Divide both sides by 10 to isolate ln(100x).ln(100x) = 12
To remove the natural log, we exponentiate both sides with base e.100x = e^12
Divide both sides by 100 to solve for x.x = (e^12) / 100
Now, by using a calculator we can find the value of e^12 and then divide it by 100 to find the value of x.
Final answer is: x = 1627.54

Two lines, A and B, are represented by the following equations: Line A: 4x + 4y = 16 Line B: x + y = 4 Which statement is true about the solution to the set of equations?
Answer:
The set of equations has an infinite number of solutions
Step-by-step explanation:
The system of linear equations represented by the following equations:
Line A: 4x + 4y = 16 and Line B: x + y = 4 are dependent.
This is because both equations represent the same line;
if we divide both sides of the equation of line A by 4, we would obtain
x + y = 4, which is basically the equation of line B
If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line.

Use the quadratic function to predict f(x) if x equals 8.
f(x) = 25x2 − 28x + 585
Answer:
1961
Step-by-step explanation:
replace x with 8
25(8)^2-28(8)+585
25(64)-28(8)+585
1600-224+585
1961
f(8) = 1961.
The quadratic function given is: f(x) = 25x2 - 28x + 585
To predict f(x) when x = 8:
Substitute x = 8 into the function:
f(8) = 25(8)2 - 28(8) + 585
f(8) = 25(64) - 224 + 585
f(8) = 1600 - 224 + 585
f(8) = 1961
Therefore, f(8) equals 1961.

The perimeter of the scalene triangle is 60 cm. The length of the longest side is 4 times that of the shortest side.
Which statements about the possible measures of the sides are reasonable? Check all that apply.
The value of x can equal 40.
The longest side can equal 30 cm.
The shortest side can equal 7 cm.
The value of x can equal 25.
The shortest side can equal 5.
Answer:
Only option C: The shortest side can equal 7 cm.
Step-by-step explanation:
Let the length of the shortest side be x cm, then the length of the longest side is 4x cm. Let the length of the middle side be y cm. Note that
[tex]x<y<4x[/tex]
The perimeter is
[tex]x+y+4x=60\\ \\5x+y=60[/tex]
A. The value x cannot be 40 cm, because then y is negative
B. If the longest side is 30 cm long, then
[tex]4x=30\\ \\x=7.5\\ \\y=60-5\cdot 7.5=22.5[/tex]
But
[tex]x+y=7.5+22.5=30\ cm[/tex]
This means that such triangle does not exist
C. If x=7 cm, then 4x=28 cm,
[tex]y=60-5\cdot 7=25\ cm[/tex]
Since,
[tex]7+25=32>28\\ \\7+28=35>25\\ \\25+28=53>7,[/tex]
such triangle exists and this option is possible
D. If x=25 cm, then y is negative
E. If x=5 cm, then 4x=20 cm and
[tex]y=60-5\cdot 5=35\ cm[/tex]
But this triangle does not exist, because [tex]5+20<35[/tex]
The longest side of this scalene triangle with a perimeter of 60 cm can equal 30 cm or the shortest side can equal 7 cm.
Further ExplanationWe can use the variables x, y and z to represent the shortest (x), medium (y) and longest (z) sides. The perimeter of a triangle is found by adding together all of the sides; this gives us the equation
x + y + z = 60
We know that the longest side, z, is equal to 4 times the length of the shortest side, x. This means that z = 4x; we can now write our equation as
x + y + 4x = 60
Combining like terms, we have
5x + y = 60
1. Checking all of the possible options, we first determine if x can equal 40:
5(40) + y = 60200 + y = 60This would give us a negative side length, which is impossible.
2. Let the longest side be 30 cm. This means that the shortest side is 1/4 of that; 30÷4 = 7.5. Using 7.5 for x,
5(7.5)+y = 6037.5 + y = 6037.5 + y - 37.5 = 60-37.5y = 22.5This is within the range of acceptable side lengths, since it is between the smallest (7.5) and the largest (30).
3. Let the shortest side be 7 cm. This means x = 7:
5(7)+y = 6035+y = 6035+y-35 = 60-35y = 25This is between the longest side, 7 cm, and the longest side, 4(7) = 28 cm. This is acceptable.
4. Let the value of x be 25:
5(25)+y = 60125+y = 60This will give us a negative value for the medium side, which is impossible.
5. Let the shortest side be 5 cm. This means x = 5:
5(5)+y = 6025+y = 6025+y-25 = 60-25y = 35This means the medium value, 35, would be greater than the longest side, 20; this is incorrect.
This means the correct options are that the longest side can be 30 cm and the shortest side can be 7 cm.

-75 = -8b - 7b
To solve for "b" you must isolate it, meaning that "b" must be the only thing on the right side of the equation.
First you must combine like terms. Like terms are numbers that have matching variables OR are numbers with out variables. In this case the like terms are -8b and -7b, since they both have the variables "b" attached.
-8b + (-7b) = -15b
so...
-75 = -15b
Next, to completely isolate b, divide -15 to both sides. Since -15 is being multiplied by b, division (the opposite of multiplication) will cancel -15 out (in this case it will make -15 one) from the right side and bring it over to the left side.
-75/-15 = -15b/-15
5 = 1b
b = 5
Check:
-75 = -8(5) - 7(5)
-75 = -40 - 35
-75 = -75

In 2014, there were approximately 900,000 sworn law enforcement officers serving in the U.S. Approximately 12% of those officers were female. How many officers were females?
Answer:
108,000 females
Step-by-step explanation:
12% of 900,000 is 108,000.
Therefore, there are 108,000 female officers in the U.S.
Answer: 108,000
Step-by-step explanation:
In 2014, 900,000 sworn law enforcement officers who were serving in the United States and 12% of those officers were female. To find the number of females that were law enforcement officers, we multiply the percentage of females by the total number of law enforcement officers. This will be:
= 12% of 900000
= 12/100 × 900000
= 0.12 × 900000
= 108,000
There were 108,000 females as law enforcement officers serving in the United States.
A patient takes a medication with a half life. Initially, there are 20 milligrams of the medication in the patient's system. After 8 hours there are 12 milligrams. How many milligrams will there be after 10 hours? Round your answer to the nearest hundredth, and do not include units
Answer:
At 10 hours there will be 10 milligrams
Step-by-step explanation:
On a graph your slope would be y= -1x+20 because there where 20 mill at 0 hours and 12 mill at 8 hours. 20-8=12 meaning 1 mill would be deluded every hour. Hope this helps.
Final answer:
Using the exponential decay formula, we can find the half-life of the medication from the initial and given 8-hour amounts and then use it to calculate the amount of medication remaining after 10 hours.
Explanation:
To determine the remaining medication after a given number of hours, we will apply the exponential decay formula which accounts for substances with a half-life. Thus, given that there are initially 20 milligrams of the medication and that it decreases to 12 milligrams after 8 hours, we need to calculate the half-life and then use it to predict the amount remaining after 10 hours.
First, finding the half-life 't1/2' can be done using the formula A = A0×2−t/t1/2, where A is the remaining amount (12 mg), A0 is the initial amount (20 mg), and t is the time elapsed (8 hours). Solving for the half-life gives us t1/2 as the unknown in this equation.
12 mg = 20 mg ×2−(8 hours)/t1/2
Reducing this equation, we find that:
t1/2 = 8 hours / (log2(20 mg/12 mg))
After finding 't1/2', we can then determine the amount remaining after 10 hours. The calculation would be as follows:
A = 20 mg ×2−(10 hours)/t1/2
This will give us the final amount of medication left in the system at the 10-hour mark, rounded to the nearest hundredth.

Kira walks 8 and a half blocks in 17 minutes. If Kira continues to walk at a steady pace, how many blocks will she walk each minute
Answer:
Half a block ( 0.5 or 1/2 )
Step-by-step explanation:
8 1/2 blocks can also be written as 8.5 blocks.
If Kira walks 8.5 blocks in 17 minutes [and continues to walk at this steady pace], divide 8.5 by 17.
8.5/17 = 0.5
So, Kira walked 0.5 or 1/2 blocks in a minute.
I hope this helps! :)
Kira walks at a rate of 0.5 blocks per minute when she walks 8 and a half blocks in 17 minutes.
Kira walks 8 and a half blocks in 17 minutes. To find out how many blocks she will walk each minute, we need to calculate the rate by dividing the total number of blocks by the total number of minutes:
Rate = Total Blocks Walked / Total Minutes
Rate = 8.5 blocks / 17 minutes
Rate = 0.5 blocks per minute.
Therefore, at a steady pace, Kira will walk half a block every minute.
