The formation of ∆ is possible .

Step-by-step explanation:

Three sides of triangle are given which are 10 , 7 & 15. And we need to determine whetherwecanmake a triangle with these three sides or not . So we know that ,

" Sum of any two sides of a triangle is Greater

than the third side "

Let ,

Here we will see by three cases. And the formation of triangle will be possible if and only of all the three cases are possible.

So , let's check ,

Case 1:-

→ a + b > c

→ 10 + 7 > 15

→ 17 > 15

Case 2:-

→ b + c > a

→ 7 + 15 > 10

→ 22 > 10

Case 3 :-

→ a + c > b

→ 10 + 15 > 7

→ 25 > 7

Since all the three cases are true Hence formation of ∆ is possible.

The net pay of Billy after 8% taxes and 10% retirement policy is $1600.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, From Billy's salary of $2000 8% of his paycheck goes to income taxes, and 10% automatically goes into retirement.

So, To obtain a net salary of Billy we'll subtract the percentage amount of 8% and 10% from the base of $2000.

Therefore, Net pay of Billy is {2000 - (8/100)×2000 - (10/100)×2000}.

= {2000 - 160 - 200}.

= (2000 - 360).

= $1640

An expression for the size of the quantity after 20 years:

f(t) = 259e^(0.2167t)

An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.

For example, 2x+3

The function A(t) that models the growth of the quantity is:

A(t) = 650 x e^(0.6t)

where t is the time in years.

To convert the equation f(t) = 259(1.24)^t to the form f(t) = ae^(kt),

we need to use the formula:

a = f(0) and k = ln(r),

where r is the growth rate.

a = f(0) = 259(1.24)^0 = 259

k = ln(r) = ln(1.24) ≈ 0.2167

Therefore, the equation f(t) in the form f(t) = ae^(kt) is:

f(t) = 259e^(0.2167t)

"Although part of your question is missing, you might be referring to this full question: Work out the sum of the interior angles of a pentagon".

A pentagon is a polygon with five sides. We can use a formula to get the pentagon's interior angle total. According to the formula, (n-2) x 180 degrees can be used to calculate the total of any polygon's internal angles. This formula can be changed to n=5 for a pentagon, giving us (5-2) x 180 degrees = 540 degrees. Consequently, a pentagon's internal angles add up to 540 degrees.

The sum of the interior angles of a pentagon can also be computed by dividing it by the number of sides, and the result can then be subtracted from 180 degrees to determine each inner angle. So, a pentagon's internal angles are each (540/5)-180 degrees, or 108 degrees.

In conclusion, a pentagon's interior angles add up to 540 degrees, and each interior angle is 108 degrees. In order to solve mathematical problems involving polygons, it can be helpful to comprehend the formulas used to calculate these numbers.

Therefore, the solution to the equation \((z + 1)^7 + (z + 1)^7 = 0\) in the complex number system is z = -1.

To solve the equation\((z + 1)^7 + (z + 1)^7 = 0\) in the complex number system, we can simplify the equation and then find the values of z that satisfy it.

Let's start by simplifying the equation:

\((z + 1)^7 + (z + 1)^7 = 0\)

We notice that both terms on the left side of the equation are identical, so we can rewrite it as:

2(z + 1)^7 = 0

Now, we can divide both sides of the equation by 2 to isolate the term\((z + 1)^7:\)

\((z + 1)^7 = 0\)

To find the solutions, we set each factor of \((z + 1)^7\)equal to zero. In other words, we set the exponent 7 to be a multiple of 2:

z + 1 = 0

From this equation, we find that z = -1.

It's important to note that complex numbers have a real and imaginary part.

In this case, since the equation simplifies to a real number, the solution is a real number (-1).

If the equation involved complex terms or the roots of unity, the solutions could include complex numbers as well.

The Future value of an annuity due of $200 each quarter for 2 1 2 years at 13%, compounded quarterly is $10263.734 ..

The future value of an annuity is the value of a group of regular payments at some point in the future. It assumes a particular rate of return, or discount rate. The higher the discount rate, the greater the annuity's future value.

P = PMT× ((1+r)ⁿ −1)/r

where:

P---> Future value of an annuity stream

PMT---->Dollar amount of each annuity payment

r -->Interest rate (also known as discount rate)

n--->Number of periods in which payments will be

We have given that

Present value for an Annuity = $200

compounded rate , r = 13%

but compounded quarterly, then, r = 13%/4

= 0.13/4 = 0.325

Number of years , n = 2 + 1/2 = 5/2

then change into quarterly, n = 5/2 × 4 = 10

Future value formula ,

F.V = PMT ( (1+i)ⁿ - 1)/r

=> Future value = 200((1+0.325)^10/0.325)

=> F.V = 10263.734

The sum of angles in a triangle is always 180 degrees. Therefore, the angle C measures 60 degrees.

In triangle ABC, we know that angle A measures 75 degrees, and angle B measures 45 degrees.

To find the measure of angle C, we can use the fact that the sum of the angles in a triangle is 180 degrees:

Angle A + Angle B + Angle C = 180

Substituting the values we know:

75 + 45 + Angle C = 180

Simplifying:

120 + Angle C = 180

Subtracting 120 from both sides:

Angle C = 60

Therefore, angle C measures 60 degrees.
