Find an equation of the circle that has center -(-5,6) and passes through (-1,1).
Answer:
[tex](x+5)^2+(y-6)^2=41[/tex]
Step-by-step explanation:
Hi there!
Equation of a circle: [tex](x-h)^2+(y-k)^2=r^2[/tex] where the circle is centered at [tex](h,k)[/tex] and r is the radius
1) Plug in the center (-5,6)
[tex](x-(-5))^2+(y-6)^2=r^2\\(x+5)^2+(y-6)^2=r^2[/tex]
2) Plug in the given point (-1,1) and solve for r²
[tex](-1+5)^2+(1-6)^2=r^2\\(4)^2+(-5)^2=r^2\\16+25=r^2\\41=r^2[/tex]
Therefore, r² is 41. Plug this back into [tex](x+5)^2+(y-6)^2=r^2[/tex]:
[tex](x+5)^2+(y-6)^2=41[/tex]
I hope this helps!
In which of the following intervals does the trigonometric inequality sec(x)
The Trigonometric inequality Sec (x)< cot(x) will hold true in π/2 < x < π.
How can a trigonometric inequality be expressed?
The intervals where the trigonometric inequality sec (x) cot (x) always holds true are what we are looking for.
This can also be expressed as: 1/cos (x) < 1/tan (x)
Now, this is only possible in the fourth quadrant, where cos x is positive and tan (x) is negative, where: π/2 < x < π.
The values for sin, cos, and tan are all positive in the first quadrant.
Only positive values for sin are present in the second quadrant.
The tan values in the third quadrant are all positive.
Only positive values for cos are present in the fourth quadrant.
Therefore the inequality Sec(x) < cot(x) will hold true in π/2 < x < π.

Ana and Darryl answered 80 calls. Ana answered 4 times as many as Darryl. How many calls did ana answer
There were 64 calls that Anna answered in this algebra question,
What is Answered calls?
Total engaged calls, another name for answered calls, is a measurement of all incoming calls that were handled by an agent during regular business hours.
Solution:
If Ana answers more calls than Darryl does, then let D be the number of calls Darryl Answered.
A + D = 80
A = 4D
4D + D = 80
5D = 80
D = 80 / 5

Suppose the population of a small town is 567 in 2011. The population decreases at a rate of 1.5% every year. What will be the population of the town in 2020?
Answer: 495 people
Step-by-step explanation:
As this involves the population in a future year, you can use the future value model for this:
= Population * ( 1 + rate of increase) ^ number of years
Number of years = 2020 - 2011
= 9 years
Rate of increase will be negative to show that it is a decrease.
= 567 * ( 1 - 1.5%) ⁹
= 494.9
= 495 people

How do you know if 3 measures can make a triangle?
To determine if three measures can make a triangle, use the Triangle Inequality Theorem. This theorem states that the sum of any two sides of a triangle must be greater than the measure of the third side.
for example
side 1 = 6
side 2 = 8
side 3 = 10
6 + 8 = 14 > 10,
therefore the three sides can make a triangle.
1. Gather the three measures of the triangle.
2. Add the two smallest side lengths together.
3. Compare the sum of the two smallest sides to the longest side.
4. If the sum of the two smallest sides is greater than the longest side, then the three measures can make a triangle.
5. If the sum of the two smallest sides is not greater than the longest side, then the three measures cannot make a triangle.

Explain about the expressions?A statement, at least two variables or integers, and one or more arithmetic operations make up a mathematical expression. This mathematical operation enables the multiplication, division, addition, or subtraction of numbers.
Combining numbers, variables, and operators to represent something's value is known as a mathematical expression. Setting two expressions equal to one another creates an equation, a mathematical statement.
An expression is a collection of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.) Expressions and phrases are similar in certain ways. Language phrases can comprise actions on their own, but they do not make up complete sentences.

If police and fire are already on an accident scene, how many feet away should you park your ambulance
It is recommended that when an ambulance arrives at an accident scene, it should park a safe distance away from the scene, at least 500 feet away.
This is to ensure the safety of the paramedics and other emergency responders, as well as to ensure that the ambulance does not impede the movement of other emergency vehicles. Additionally, it is also to protect the privacy of the individuals involved in the accident and ensure that the scene is not tampered with.
It is also important to follow any additional instructions given by the police or fire department at the scene, as they may have specific parking instructions based on the situation.

The true statement is 6 less than 10
How to determine the true statementFrom the question, we have the following parameters that can be used in our computation:
(-2) (-3) less greater than equal than 8- (-2)
We start by evaluating each expression
So, we have the following representation
(-2) (-3) = 6
8- (-2) = 10
Substitute the known values in the above equation, so, we have the following representation
6 less greater than equal than 10
6 is less than 10

Next $3,500
4. 5%
Over $7,000
7%
The annual state tax withheld for Kelly Waxman would be 1,662.50 dollars.
Therefore the answer is d) $1,662.50.
Here is the breakdown of the calculation:
Kelly's salary of $30,000 minus the married exemption of $3,000 = $27,000
The first $3,500 are taxed at 3%, which is
= 0.03×3500
= $105
The next $3,500 are taxed at 4.5%, which is
= 0.045×3500
= $157.50
The remaining $27,000 - $3,500 - $3,500 = $20,000 are taxed at 7%, which is
= 0.07×20000
= $1,400
Adding all three amounts together: $105 + $157.50 + $1,400 = $1,662.50. It is the annual state tax withheld.
