What is the sum of the measures of the interior angles of a 13 sided polygon

Snezhnost [94]

Sum of all interior angles of a polygon

180( n - 2) where n = number of sides in the polygon

now, if n = 19, the polygon has 19 sides, then 180( 19 - 2)

The future value of $1,000 invested at 8% compounded semiannually for five years is $\bold{\$ 1,480}$

<u>Solution:</u>

$\bold{A = P (1 + i )^{n}}$ ----------- equation 1

A = future value

P= principal amount

i = interest rate

n = number of times money is compounded

P = 1000

i = 8 %

$\mathrm{n} = \text { compounding period } \times \text {number of years}$

(Compounding period for semi annually = 2)

$\mathrm{n} = \text { compounding period } \times \text {number of years}$

Dividing “i” by compounding period

$i = \frac{8 \%}{2} = 0.04$

Solving for future value using equation 1

$\begin{array}{l}{A = 1000(1 + 0.04)^{10}} \\\\ {=1000 (1.04)^{10}}\end{array}$

$= 1480.2$

$\approx 1,480 \$$

How do I solve this equation?

Keith_Richards [23]

Answer:

$y=\frac{7}{2}x+11$

Step-by-step explanation:

To solve, we need to find the y-intercept (b). In order to find the y-intercept, we can plug in the slope and the (x,y) coordinate pair given to us into the equation to solve for the y-intercept:

y=mx+b

4=(-7/-2)*-2+b

4=14/-2+b

4=-7+b

Add 7 to both sides

b=11

Therefore the equation is:

$y=\frac{7}{2}x+11$ (note that the fraction is positive since the two negatives cancel out)

Write an equation of a line that passes through the point (4,3) and is perpendicular to the graph of the equation y=−13x+4.

lilavasa [31]

Answer:

y = -13x + 55

Step-by-step explanation:

perpendicular formula : m1 × m2 = -1

y = -13x + 4

now we take the grafient of the equation which is 13 :

m × 13 = -1

m = -13

so now we hv a new gradient then we can find the equation use the formula y = mx + c :

m = -13 point = ( 4 , 3 )

sub them into the formula,

3 = -13 (4) + c

3 = -52 + c

3 + 52 = c

55 = c

c = 55

now we rewrite again the c and the m to become a complete equation : y = -13x + 55
