●Perimeter= 160 ft

●All sides are given except the left side

●Left side is x

So, 30 + 10 + 45+ 15 + x = 160ft

135 ft+ x= 160ft

X feet= 160 - 135

= 25 ft

ANS= 25 FEET

I need help for this question

Dmitry [639]

X = 56 + 106
162 = x

Because the radius is 56, and the line outside of SU is 106, so add the two values then you’ll have x

Cos(x+y)cos(x-y)=cos^2(x)-sin^2(y)<br> Verify the identity

GenaCL600 [577]

Answer: Verified.

Step-by-step explanation: The given identity involving trigonometric ratios is

$\cos(x+y)\cos(x-y)=\cos^2x-\sin^2y.$

We have

$L.H.S.\\\\=\cos(x+y)\cos(x-y)\\\\=\left(\cos x\cos y-\sin x\sin y\right)\left(\cos x\cos y+\sin x\sin y\right)\\\\=\left(\cos x\cos y\right)^2-\left(\sin x\sin y\right)^2\\\\=\cos^2x\cos^2y-\sin^2x\sin^2y\\\\=\cos^2x(1-\sin^2y)-(1-\cos^2x)\sin^2y\\\\=\cos^2x-\cos^2x\sin^2y-\sin^2y+\cos^2x\sin^2y\\\\=\cos^2x-\sin^2y\\\\=R.H.S.$

Therefore, L.H.S. = R.H.S.

Thus, the given identity is verified.

When Rahul began 7th grade, he put his savings of $3,000 in an account that compounded interest annually. He hoped to have $6,00

DENIUS [597]

Answer:

12%

Step-by-step explanation:

You are going to want to use a modified compound interest formula, as shown below. This version of the compound interest formula is what you use to solve for the interest rate.

$r=n[(\frac{A}{P})^{1/nt}-1]$

r = interest rate (decimal)

n = numbers of times compounded (annually)

A = total amount

P = principal amount

<em>t = time (years)</em>

Now, lets plug in the values:

$r=1[(\frac{6,000}{3,000})^{1/(1)(6)}-1]$

$r=.12246$

Next, multiply <em>r </em>by 100 to get our answer:

$.12246(100)= 12.246$

The last step is to round our answer to the nearest whole number:

12.246 -> 12
