Julia and Rodney decided to invest 15% of their salaries.The table shows their principal balance,interest rate,and type of inter
Masja [62]
On the account with interest compounded annually, the account balance will be
  P*(1 +r)^t
  4500*1.06³ = 5358.57
so the interest earned will be
  5358.57 -4500 = 859.57

On the account with simple interest, the interest earned will be
  I = Prt
  I = 4500*.06*3
  I = 810.00

The total interest earned on the two accounts will be
  $859.57 +810.00 = $1669.57 . . . . . . . . selection A

Solve x2 - x - 30 = 0 by factoring.
likoan [24]

Answer:

x=6, x=-5

Step-by-step explanation:

Factoring this quadratic gets you (x-6)(x+5)=0, for this to be possible, either x-6 or x+5 has to be zero, so therefor x is 6, or x is -5

In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches. Find the measure of ∠P to the nearest degree.
Sophie [7]

Given:

In ΔNOP, n = 910 inches, o = 110 inches and p=820 inches.

To find:

The measure of ∠P to the nearest degree.

Solution:

According to the law of cosine:

\cos A=\dfrac{b^2+c^2-a^2}{2bc}

Using law of cosine in triangle NOP, we get

\cos P=\dfrac{n^2+o^2-p^2}{2no}

Putting the given values, we get

\cos P=\dfrac{(910)^2+(110)^2-(820)^2}{2(910)(110)}

\cos P=\dfrac{828100+12100-672400}{200200}

\cos P=\dfrac{167800}{200200}

\cos P=0.83816

Taking cos inverse on both sides, we get

P=\cos^{-1}(0.83816)

P=(33.05367)^\circ

P\approx 33^\circ

Therefore, the measure of ∠P is 33°.
