We can use the Pythagorean Theorem to solve this:

35^2 + 28^2 = x^2

x^2 = 1225 + 784

x^2 = 2009

x = ~44.821

~44.8 mi

28 + 21 = 49

49 mi

We can again use the Pythagorean Theorem

35^2 + 49^2 = x^2

x^2 = 1225 + 2401

x^2 = 3626

x = ~60.216

~60.2 mi

Part A. Solve -np - 80 < 60 for 'n'. Show your work.

skelet666 [1.2K]

Part A:
- np -80 <60
Adding 80 both sides
- np < 140
Dividing by -p both sides
n > -140/p
Part B:
2a - 5d =30
5d = 2a-30
d= (2a-30)/5

What color is the parabola whose algebraic expression is

german

It is the blue one. By doing the vertex formula we can see the x value of the vertex is -3/4. The blue one best represents that as the negative A value shows the parabola will be facing down too and have a maximum not a minimum for the vertex

ioda

Dave will have $12,728 after 15 years, if he has $8000 to invest for 15 years. He finds a bank that offers an interest rate of 3.1% compounded monthly.

Step-by-step explanation:

The given is,

Investment = $ 8000

No. of years = 15 years

Interest rate, i = 3.1 %

( compounded monthly )

Step:1

For for calculating future value with compound interest monthly,

$A = P (1 +\frac{r}{n})^{nt}$ .................(1)

Where,

A = Future amount

P = Initial investment

r = Rate of interest

n = Number of compounding in a year

t = Time period

Step:2

From given values,

P = $8000

r = 3.1%

t = 15 years

n = 12 ( for monthly)

Equation (1) becomes,

$A = 8000( 1+\frac{0.031}{12} )^{(12)(15)}$

$= 8000 (1+0.002583)^{180}$

$= 8000(1.002583)^{180}$

$= 8000(1.591059)$

$=12728.48$

A = $ 12728.48

Result:

Dave will have $12,728 after 15 years, if he has $8000 to invest for 15 years. He finds a bank that offers an interest rate of 3.1% compounded monthly.
