What is the length of the hypotenuse of the trim angle ?

Ksju [112]

So for this, you'll be using the pythagorean theorem, which is $leg^2+leg^2=hypotenuse^2$ . In this case, 10 and 24 are the legs, and AB is the hypotenuse. Our equation will be $10^2+24^2=AB^2$

Firstly, solve the exponents: $100+576=AB^2$

Next, combine 100 and 576: $676=AB^2$

And lastly, square root both sides to get $26=AB$

And in short, Line AB is 26 ft, or the first option.

Answer:

$\$164.5$

Step-by-step explanation:

Bonnie deposits $70.00 into a new savings account.

The account earns 45% simple interest per year.

She neither added or removed from the savings account for 3 years.

We know that,

$i=\dfrac{P\cdot r\cdot r}{100}$

here,

i = interest,

P = principal = $70,

r = rate of interest = 45%,

t = time = 3 years,

Putting the values,

$i=\dfrac{70\cdot 45\cdot 3}{100}=\$94.5$

So the total amount will be,

$=\text{Principal}+\text{Interest}$

$=70+94.5$

$=\$164.5$

How to do this problem

True [87]

One way in which to approach this proof would be to convert

1 (cos x)^2
------------- into ---------------- . Next, note that 1 - (sin x)^2 = (cos x)^2
(tan x)^2 (sin x)^2 and that 1 - (cos x)^2 = (sin x)^2.

Then we have:

(cos x)^2 (cos x)^2
------------- = -------------------- which is a true equation
(sin x)^2 (sin x)^2
