Given the kite below, if NO = 5 and OM = 12, what is the value of NM?

tester [92]

Answer:

NM = 13

Step-by-step explanation:

pythagorean theorem: $a^{2} + b^{2} = c^{2}$

a or NO = 5

b or OM = 12

c or NM = ?

plug in what is known:

⇒ $5^{2} + 12^{2} = c^{2}$

⇒ $25 + 144 = c^{2}$

⇒ 169 = $c^{2}$

square root each side of the equation:

⇒ $\sqrt{169} = \sqrt{c^{2} }$

solve:

⇒ 13 = c

Jill invested $20,000 in an account that earned 5.5% annual interest, compounded annually. What is the value of this account aft

noname [10]

The value of this account in 10 years is given by the formula:

FV = P*(1+r)^t

where FV is the future value in the account after 10 years(to be calculated)

P is the principal invested at the beginning

r is the interest rate and

t is the time horizon in years

Given, Invested Amount (P) = 20,000

Interest rate (r) = 5.5% = 0.055

Time horizon (t) = 10 years = 10

Substituting the formula, FV = 20,000*(1+0.055)^10 = 20,000*1.055^10 = 20,000*1.708144458 = 34,162.89

The value of this account after 10 years =$34,162.89 (Rounded to the nearest cent)

The volume of a ball is 288pi cm cubed. Find the dimensions of a rectangular box that is just large enough to hold the ball.

asambeis [7]

Answer:

r = 6 cm

Step-by-step explanation:

The volume of a sphere is 288 pi cm tripled . Find the lenght of a radius of a SPHERE.What is the answer and how did you do it?

-------------------

The volume of a sphere of radius r is:

V+=+4%2Api%2Ar%5E3%2F3

It's r cubed, not tripled. meaning r*r*r

-------------------

288pi+=+4%2Api%2Ar%5E3%2F3

864+=+4r%5E3

r%5E3+=+216

r = 6 cm
