Find the balance in an account with $7,000 principal earning 5% interest compounded quarterly

nadya68 [22]

Answer:

The balance is $\$11,505.34$

Step-by-step explanation:

we know that

The compound interest formula is equal to

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

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=10\ years\\ P=\$7,000\\ r=0.05\\n=4$

substitute in the formula above

$A=\$7,000(1+\frac{0.05}{4})^{4*10}=\$11,505.34$

What is the sum of the solutions of the equation 1.5x^2 - 2.5x -1.5 = 0? Round to the nearest hundredth.

BARSIC [14]

Answer:

$Sum = 1.67$

Step-by-step explanation:

Given:

$1.5x^2 - 2.5x -1.5 = 0$

Required

Determine the sum of the solutions

This question will be answered using quadratic formula:

$x = \frac{-b\±\sqrt{b^2 - 4ac}}{2a}$

Where:

$a = 1.5$

$b = -2.5$

$c = -1.5$

So, we have:

$x = \frac{-(-2.5)\±\sqrt{(-2.5)^2 - 4*1.5*-1.5}}{2*1.5}$

$x = \frac{2.5\±\sqrt{6.25 +9}}{3}$

$x = \frac{2.5\±\sqrt{15.25}}{3}$

$x = \frac{2.5\±3.91}{3}$

$x = \frac{2.5+3.91}{3}$ or $x = \frac{2.5-3.91}{3}$

The sum of the solution is then calculated as:

$Sum = \frac{2.5+3.91}{3} + \frac{2.5-3.91}{3}$

Take L.C.M

$Sum = \frac{2.5+3.91+2.5-3.91}{3}$

$Sum = \frac{5}{3}$

$Sum = 1.67$

Can someone plz solve for A&B? Plz and if you do thank you so much :)

Anna71 [15]

Answer:

Part a-

area= 35

perimeter= 31

part b-

area= 25

perimeter= 18

Step-by-step explanation:

to find the area of a triangle you multiply 1/2Bh

so for part A:

A= $\frac{1}{2}$ (10)(7) (honestly, you can just input the whole equation into the calculator)

A=(5)(7)

A= 35

and for part B:

A= $\frac{1}{2}$ (8.34)(6)

A= (4.17)(6)

A=25.02 (or just 25)

THEN, to find the perimeter you add up all of the sides

so for part A:

P= 14 + 10 + 7 = 31

and for part B:

P= 4 $\frac{1}{3}$ + 8 $\frac{1}{3}$ + 5 $\frac{1}{3}$ = 17 $\frac{3}{3}$ or 18

I hope this helps :)
