Answer:
C
Step-by-step explanation:
the sum of the exterior angles of a polygon = 360°
the exterior angle to 93° = 180° - 93° = 87°
summing the exterior angles and equating to 360
x + 52 + 87 + x + 3 + 78 = 360 , that is
2x + 220 = 360 ( subtract 220 from both sides )
2x = 140 ( divide both sides by 2 )
x = 70
Answer:
C. 70°
Step-by-step explanation:
93 is as internal angle the supplementary angle to the external angle at that point (together they are 180°).
the sum of the exterior angles of a polygon is 360°.
we have here
52°
180-93 = 87°
x+3
78
x
so,
52 + 87 + 78 + x + 3 + x = 360
220 + 2x = 360
2x = 140
x = 70°

A circle is centered at the point (-7, -1) and passes through the point (8, 7).
The radius of the circle is ___ units. The point (-15, ___) lies on this circle. What are the answers?
Answer:
Find Radius using distance formula.
\(radius = \sqrt{(8 -- 7)^2 +(7--1)^2} \\\)
=\(\sqrt{15^2 + 8^2} = \sqrt{225 + 64 } =\sqrt{289} = 17 units\)
Since the point (-15, y) lies on the circle. The distance between (-7, -1) and
(-15, y ) will be 17 units.
So again using distance formula we will find y.
\(radius = \sqrt{(-7 --15)^2 + (-1-y)^2} \\\\17 = \sqrt{8^2 + (y+1)^2}\\\\squaring \ both \ sides \\\\289 = 64 + (y+1)^2\\\\289-64=(y+1)^2\\\\225 = (y+1)^2\\\\taking \ squaring \ root\\\\15 = y+1\\\\y=14\)

How do you find the derivative of the function using the definition of derivative f(x)=10?
The derivative of of f(x) = 10 is 0
The derivative of a function is the measure of the rate of change of the function. They are fundamental to the solution of problems in calculus and differential equations.
Here the function is not changing as 10 is a constant. So, if f(x) = c where c is a constant then f'(x) = 0 as the derivative of a constant is always zero.
Mathematically:
d(f(x))/dx = \(\lim_{h \to 0}\) (f(x+h) - f(x))/h
There is no x to substitute for x + h so no difference is noticed:
\(\lim_{h \to 0}\) (f(x+h) - f(x))/h = \(\lim_{h \to 0}\) (10 - 10)/h = 0
Hence, the derivative of f(x) = 10 is 0

A fair die is rolled 5 times. What is the probability of having no 1 and no 2 among the rolls
Answer:
40%
Step-by-step explanation:
There are 5 options to roll: 1, 2, 3, 4, and 5.
This means you have a 1 out of 5 chance of rolling each number.
This question is asking for 1 AND 2, not just one number. So, we have a 2 out of 5 chance of rolling that, because 2 options are acceptable instead of just one number.
I'm not sure which form you are looking for, but 2 out of 5 is the same as saying 2/5. Most probability solutions are wanted as a percentage. To find that just solve 2/5, which is 0.4. Move the decimal to the right twice, and that is a 40% chance.
what is the arithmetic mean of all of the positive two-digit integers with the property that the integer is equal to the sum of its first digit plus its second digit plus the product of its two digits?
The arithmetic mean is 59.
What is arithmetic mean?
It is the sum of collection of numbers divided by the count of the numbers.
Conider AB is the nuber satisfying the condition. Hence,
\(10A+B=A+B+A\times B\\9A=A\times B\\\)
Since AB is a two digit number hence, \(A\neq 0\\\). Hence, divide both sides by \(A\).
\(9=B\)
Hence, B is 9 and A can take any value from 1 to 9.
Hence, numbers are 19, 29, 39, 49, 59, 69, 79, 89,99.
Now, calculate arithmetic mean as follows:
\(AM=\frac{Sum \ of \ numbes}{Count \ of \ numbers}\\=\frac{19+29+39+49+59+69+79+89+99}{9}\\=59\)

Answer: The Philadelphia Eagles tried to blow a 19-point lead to the Chicago Bears, but managed to hold on for a 22-14 victory in a rematch of the NFC Wild Card Game to move to 5-4 on the year. Philadelphia allowed the Bears to score 14 unanswered points after taking a 19-0 lead in the third quarter, but put together one of their most impressive drives of the season in taking 8:14 off the clock in the fourth quarter, converting four consecutive third downs in the most critical junction of the game.
Chicago never got the ball back after Jake Elliott hit a 38-yard field goal with 26 seconds left to make it 22-14. Bears tight end Adam Shaheen muffed the catch on the kickoff and the Eagles recovered to deny Chicago a last ditch effort for a Hail Mary and an attempt to tie the game with a two-point conversion.
Jordan Howard scored a touchdown in his first game against his former team, finishing with 19 carries for 82 yards and a touchdown. Zach Ertz had his best game of the season as the Eagles tight end had nine catches for 103 yards and a touchdown, a 25-yard catch for his second score of 2019.
The Bears had just nine total yards in the first half, but rallied back in this game with two scoring drives in three possessions between the third and fourth quarter. Chicago's offense had no turnovers, but finished with just 164 yards of offense. Mitchell Trubisky went 10 of 21 for 125 yards with no touchdowns and a 66.6 passer rating. The Bears have lost their fourth consecutive game after a 3-1 start to the season, falling to 3-5 and remaining in last place in the NFC North.
Step-by-step explanation:
The number of points scored by the eagles is 19 points.
Suppose the points scored by the bears, eagles, and cowboys are x, x+2, x+4 respectively.
It is given the product of the points scored by the bears and cowboys was 37 more than the 8 times the sum of the points scored by the eagles and cowboys.
This means, x(x+4) =37+8(x+2+x+4)
x(x+4) =37+8(2x+6)
\(x^{2} +4x = 37+16x+48\)
\(x^{2} -12x-85=0\), which is a quadratic equation.
What is a quadratic equation?Any equation in the form \(ax^{2} +bx+c=0\) is called a quadratic equation where \(a\neq 0\).
\(x^{2} -17x+5x-85=0\)
\(x(x-17)+5(x-17)=0\)
\((x-17)(x+5)=0\)
\(x=17\)
So, eagles scored x+2 = 17+2 =19 points.
Therefore, The number of points scored by the eagles is 19 points.

Richard Gaziano is a manager for Health Care, Inc. Health Care deducts Social Security, Medicare, and FIT (by percentage method) from his earnings. Assume a rate of 6.2% on $118,500 for Social Security and 1.45% for Medicare. Before this payroll, Richard is $1,000 below the maximum level for Social Security earnings. Richard is married, is paid weekly, and claims 2 exemptions. What is Richard’s net pay for the week if he earns $1,700?
Richard's net pay for the week, considering Social Security, Medicare, and FIT deductions, can be calculated by subtracting the total deductions from his gross earnings.
First, let's determine the amount deducted for Social Security. The Social Security rate is 6.2%, and the maximum earnings subject to this deduction are $118,500. Since Richard is $1,000 below the maximum level, the amount subject to Social Security deduction is $1,000. Therefore, the Social Security deduction is 6.2% of $1,000.
Next, we calculate the Medicare deduction. The Medicare rate is 1.45%, and it is applied to the entire earnings of $1,700.
To calculate the FIT deduction, we need additional information about Richard's taxable income, tax brackets, and exemptions. Without this information, we cannot provide an accurate calculation for the FIT deduction.
Finally, we subtract the total deductions (Social Security, Medicare, and FIT) from Richard's gross earnings of $1,700 to obtain his net pay for the week.

What is the equation for the nth term of the sequence
And what is the 52nd term of the sequence. -8,-12,-16
Given:
The sequence is -8, -12, -16.
To find:
The nth and 52th term of the given sequence.
Solution:
We have,
-8, -12, -16
It is an AP because the difference between consecutive terms are equal. Here, first term is -8 and the common difference is
\(r=a_2-a_1\)
\(r=-12-(-8)\)
\(r=-12+8\)
\(r=-4\)
The nth term of an AP is
\(a_n=a+(n-1)d\)
Where, a is first term and d is common difference.
Putting a=-8 and d=-4, we get
\(a_n=-8+(n-1)(-4)\)
\(a_n=-8-4n+4\)
\(a_n=-4-4n\)
Putting n=52, we get
\(a_{52}=-4-4(52)\)
\(a_{52}=-4-208\)
\(a_{52}=-212\)
Therefore, the equation for the nth term of the given sequence is \(a_n=-4-4n\) and the 52nd term of the sequence is -212.
