sonja wants to have $14000 in 13 years. calculate how much she should invest now at 6% interest, compounded semiannually in orde
mariarad [96]
She should invest $6491.73.

The equation we use to solve this is in the form
A=p(1+\frac{r}{n})^{nt}, 
where A is the total amount in the account, p is the principal invested, r is the interest rate as a decimal, n is the number of times per year the interest is compounded, and t is the amount of time.

A in our problem is 14000.
p is unknown.
r is 6% = 6/100 = 0.06.
n is 2, since it is compounded semiannually.
t  is 13.

14000=p(1+\frac{0.06}{2})^{13*2}
\\
\\14000=p(1+0.03)^{26}
\\
\\14000=p(1.03)^{26}
\\
\\\text{Dividing both sides by }1.03^{26}\text{, we have}
\\
\\\frac{14000}{1.03^{26}}=\frac{p(1.03)^{26}}{1.03^{26}}
\\
\\6491.73\approx p

If BD bisects ABC, m DBC =79 and ABC = (9x-4) find the value of x
zimovet [89]

Answer:

x=18

Step-by-step explanation:

set up the equation:

DBC+DBC=ABC

79+79=(9x-4)

Simplify both sides of the equation.

79+79=9x−4

79+79=9x+−4

(79+79)=9x−4(Combine Like Terms)

158=9x−4

158=9x−4

Flip the equation.

9x−4=158

Add 4 to both sides.

9x−4+4=158+4

9x=162

Divide both sides by 9.

9x /9  =  162 /9

x=18

What is the percent of change from 4 to 5?
enot [183]

Answer:

The formula for calculating the percent change in a value between two points in time is:

p

=

N

−

O

O

⋅

100

Where:

p

is the percent change - what we are solving for in this problem.

N

is the New Value - 5 in this problem.

O

is the Old Value - 4 in this problem.

Substituting and solving for

p

gives:

p

=

5

−

4

4

⋅

100

p

=

1

4

⋅

100

p

=

100

4

p

=

25

There was a 25% increase from 4 to 5.
