37 + 65 + 25x + 3 = 180
105 + 25x = 180
25x = 180
25x = 75

On the first january 2014 carol invested some money in a bank account the account payes 2.5% compound interest per year on 1st j

Sladkaya [172]

Answer:

$23,360

Step-by-step explanation:

Calculation to determine how much carol originally invested in the account

First step is to divide £23517.60 by 1.025

= (23,517.60)/(1+.025)

= (23,517.60)/1.025

=$22,944

Second step is to add back the $1,000 withdrew

=$22,944+$1,000

=$23,944

Now let calculate how much carol originally invested in the account

$23,944=1.025P

Divide both side by 1.025

P=$23,944/1.025

P=$23,360

Therefore the amount that carol originally invested in the account is $23,360

Find the shaded area. Round your answer to the nearest tenth.

Fofino [41]

Answer:

${22cm}^{2}$

to the nearest tenth

Step-by-step explanation:

find the area of the semi circle

$\frac{\pi \times 5}{2} = {7.85cm}^{2}$

find area of the whole shape

$5 \times 6 = {30cm}^{2}$

then subtract both areas to get shaded area

$30 - 7.85 = 22.15$

Help please and help me understand how to solve

natulia [17]

Answer:

Step-by-step explanation:

You have a right triangle here. The way to solve for a missing side in a right triangle is to use Pythagorean's Theorem. You can't use right triangle trig because you don't have an angle. Pythagorean's Theorem is, in this case,

$x^2=6^2+(2\sqrt{3})^2$ and

$x^2=36+12$ and

$x^2=48$ so

$x=\sqrt{48}$ which simplifies down to

$x=4\sqrt{3}$

A force of 128 lb is required to hold a spring stretched 2 ft beyond its natural length. How much work W is done in stretching i

Agata [3.3K]

We have that the workdone in stretching natural length to is mathematically given as

W=9/2lbft

<h3>Workdone in stretching natural length</h3>

Question Parameters:

A force of 128 lb is required to hold a spring stretched 2 ft <em>beyond </em>its natural length.
Stretching it from its natural length to 9 inches beyond its natural length

Generally the Hookes equation for the Force is mathematically given as

F=Kx

Where

3.2lb=2ft*k

Thereofore

k=16

Force becomes

f=kx

f=16x

Hence

$W=8[x^2]^{3/4}_{0}$

W=9/2lbft
