Answer 1
36 degrees (it's an acute angle)
Answer 2
The sum of the measures of the interior angles of an n-sided polygon is 180(n - 2).

A pentagon has 5 sides, so for a pentagon, the sum of the measures of the interior angles is

180(n - 2) =

= 180 (5 - 2)

= 180 * 3

= 540

Since this pentagon is regular, all interior angles are congruent.
Each one measures 540/5 = 108, or 108 degrees.

The upper 108-degree angle together with the 2 angles marked x form a straight angle.

x + x + 108 = 180

2x + 108 = 180

2x = 72

x = 36

After t years, the amount of money in a savings account that earns simple interest is p + prt, where p is the starting amount and r is the yearly interest rate. factor this expression.

Answers

using I=PRT/100
replacing the given information;
(p+prt)=P×r×t


⇒p+prt=P×rt
P=(p+prt)/(rt)
Principal(P)= (p/rt)+p
                   =p((1/rt)+1)

Final answer:

The equation of simple interest p + prt can be factored by taking out the common factor p, resulting in a factored expression of p(1 + rt).

Explanation:

The equation p + prt represents the total amount of money in a savings account after t years when interest is earned at a simple interest rate of r on the principal amount p. To factor this expression, we look for the greatest common factor present in each term. Here, the common factor is the principal amount p.

Therefore, the factored form of the expression is p(1 + rt). This shows that the total amount is composed of the initial principal plus the product of the principal, the rate, and the time.

This differs from compound interest, where the interest earned is added to the principal at each compounding period, leading to interest on interest. Simple interest calculations are straightforward and don't involve this compounding effect, making it simpler to calculate future values manually or using online calculators.

Identify the 7th term of the geometric sequence in which a2 = 324 and a4 = 36

Answers

the answer is 4/3 or -4/3

Answer:

4/3

Step-by-step explanation:

a2 = 324 and a4 = 36

second term is 324  and fourth term is 36

[tex]a_n= a_1(r)^{n-1}[/tex]

To get second term, replace n with 2

[tex]a_2= a_1(r)^{2-1}[/tex]

[tex]a_2= a_1(r)[/tex]

replace a2 with 324

[tex]324= a_1(r)[/tex] -----------> equation 1

To get fourth term , replace n with 4

[tex]a_4= a_1(r)^{4-1}[/tex]

[tex]a_4= a_1(r)^3[/tex]      

Replace the value

[tex]36= a_1(r)[/tex]  -----------> equation 2

divide second equation by first equation

[tex]36= a_1(r)^3[/tex]    divide by [tex]324= a_1(r)[/tex]

1/9 = r^2

take square root on both sides

1/3= r

now we find a1

[tex]324= a_1(r)[/tex]  

[tex]324= a_1(\frac{1}{3})[/tex]

multiply by 3 on both sides

972= a_1

So a1= 972,  r= 1/3

now find out 7 term by replacing 'n' with 7

[tex]a_7= 972(\frac{1}{3})^{7-1}[/tex]

So 7th term is 4/3

Find a polynomial function of lowest degree with rational coefficients that has the given numbers as some of its zeros 2+i, 2

Answers

Final answer:

To find a polynomial with given zeros 2+i and 2, include the conjugate 2-i to ensure rational coefficients, resulting in the polynomial x^2 - 4x + 3.

Explanation:

Finding a Polynomial with Given Zeros

To find a polynomial function of the lowest degree with rational coefficients that has 2+i and 2 as some of its zeros, you should remember that complex zeros in polynomials with real coefficients come in conjugate pairs. This means that if 2+i is a zero, so is its conjugate 2-i. You now have three zeros: 2, 2+i, and 2-i.

The polynomial with these zeros can be written as (x-2)(x-(2+i))(x-(2-i)). To find the polynomial, we simply multiply these factors:

(x-2)(x-2+i)(x-2)(x-2) - i(x-2)

Now add the resulting quadratics:

(x-2)2 - i2

This results in:

x2 - 4x + 4 - 1

Which simplifies to x2 - 4x + 3. Thus, the required polynomial function of the lowest degree is x2 - 4x + 3.

Answers

Answer: x = 5

------------------------------------------
------------------------------------------

Explanation:

We have a right triangle as indicated by the square angle marker. Two of the sides are known: specifically the hypotenuse (13) and one of the legs (12). The other leg (x) is unknown.

We can use the Pythagorean Theorem to find x

a = 12 is one of the known legs
b = x is the unknown leg
c = 13 is the hypotenuse

Pythagorean Theorem:
a^2 + b^2 = c^2
12^2 + x^2 = 13^2
144 + x^2 = 169
144 + x^2-144 = 169-144 ... subtract 144 from both sides
x^2 = 25
sqrt(x^2) = sqrt(25)  ... apply square root to both sides
x = 5 

Side Note: Keep in mind that x can't be negative so it doesn't make sense to use the plus/minus here. We'll only stick with the positive version.

Each morning Papa notes the birds feeding on his bird feeder. So far this month, he has seen 59 blue jays, 68 black crows, 12 red robins, and 1 cardinal. If 300 birds visit Papa'S bird feeder, how many blue jays can he expect to see?

Answers

Add all of the birds together.

59 + 68 + 12 + 1 = 140

Solve what percentage 59 is of 140.

x * 140 = 59
Divide both sides by 140.
x = .421428571

Multiply 300 by that percent.

300 * .421428571 = 126.428571 which rounds up to 126.

Papa can expect 126 blue jays.

Final answer:

The restriction of the outright worth of x as x methodologies 0 will be 0. Outright worth guarantees that the result is non-negative, and as x methodologies zero from one or the other side, the outcome stays at 0.

Explanation:

The inquiry you're posing relates to the furthest reaches of the outright worth capability as the variable x methodologies are the worth of nothing. In science, explicitly in math, we assess cutoff points to comprehend the way of behaving of capabilities as they approach a specific point.

To track down the breaking point as x methodologies 0 of the outright worth of x, signified as lim x→0 |x|, we want to think about the meaning of outright worth. The outright worth of a number is the non-negative worth of that number regardless of its sign. In this manner, as x methodologies 0 from either the positive or negative side, the outright worth of x will likewise move toward 0.

Consequently, the cutoff is 0, since as x gets increasingly close to nothing, so does the outright worth of x.

The midpoint of UV is (5, -10). The coordinates of one endpoint are U(3,6). Find the coordinates of endpoint V.

How do I use the midpoint formula for this?

Answers

The coordinates of the midpoint of a line segment joining two points (x₁,y₁) and (x₂, y₂) is given by
[(x₁+x₂)/2, (y₁+y₂)/2].

Given:
(x₁,y₁) = (3,6)  for the point U.

For the midpoint,
(x₁+x₂)/2 = 5   or x₁ + x₂ = 10
(y₁+y₂)/2 = -10 or  y₁ + y₂ = -20

Therefore, the coordinates of V are
3 + x₂ = 10     =>  x₂ = 7
6 + y₂ = -20  =>   y₂ = -26

Dylan's hiking club is planning to stay overnight at a camping Lodge. Each large room can hold 15 hikers. There are 154 hikers. How many rooms will they have?

Answers

Since we're figuring out rooms for real people, we'll need to round our answer up since a partial group of 15 will need a room, too. First, divide out the hikers by the number of rooms:
154 ÷ 15 = 10.26666...

They'll need 11 rooms to accommodate everyone
First of all, you need to compare the two statements. That will be;
1 room=15 hikers
Y=154 hikers
I represented the unknown number of rooms with Y. So now we need to find Y. The next step is to cross and multiply. 15 will multiply Y to give 15Y. And 154 will multiply 1 to give 154. That will be;
15Y=154
Divide both sides by 15. That will be;
Y=154/15
Y=That will be 10.27 which means 10 rooms. But 4 hikers will remain. In other to accommodate the remaining 4 hikers, an extra room will be taken. Which will make 11 rooms. Hope that helped. Have a nice day

solve for y 3x - 5y = 8

Answers

y= -8/5 + 3/5 hope this helps

Final answer:

To solve for y in the equation 3x - 5y = 8, we subtract 3x from both sides and then divide by -5, resulting in y = (3/5)x - 8/5.

Explanation:

Solving for y in the equation 3x - 5y = 8

To solve for y in the equation 3x - 5y = 8, we need to isolate y on one side of the equation. Here are the steps:

Start with the original equation: 3x - 5y = 8.

Subtract 3x from both sides of the equation to get -5y = -3x + 8.

Divide each term by -5 to solve for y: y = (3/5)x - 8/5.

So the solution for y in terms of x is y = (3/5)x - 8/5.

Step-by-step explanation:

Michelle has an 85-page manuscript. To calculate the total cost of printing equation will be  

85c - 0.05( 85c ) = T

where c = cost per page and T = total cost on editing 85 pages.

If total cost of editing is $161.50, then we have to find the best quality of editing Michelle can get.

85(c) - (0.05)(85c) = 161.50

85c - 4.25c = 161.50

80.75c = 161.50

⇒ c = $ 2 per page

As it has been given in the question that express proof reading costs $2.00 per page, so the best quality of editing Michelle can get is option (a) Express proof reading
