Answer:

w(w² + 3)

Step-by-step explanation:

Given the expression

w³ + 3w

Since w is common to the terms w³ and 3w, we will factor it out from the expression as shown;

w³ + 3w

w(w²)+ 3(w)

w(w² + 3)

This gives the required expression

A. Solve for y.<br> B. What is the measure of the missing angles?

Alik [6]

Answer: A.) y = 15 B.) (5y + 3)° = 78° (4y + 8)° = 68° and 34°

Steps:
180° - 146° = 34°

180 = 34 + (5y + 3) + (4y + 8)
180 - 34 = (5y + 3) + (4y + 8)
146 = (5y + 3) + (4y + 8)
146 = 5y + 3 + 4y + 8
146 = 9y + 11
146 - 11 = 9y
135 = 9y
135/ 9 = y
15 = y

(5y + 3)
5(15) + 3
75 + 3
78
(5y + 3) = 78

(4y + 8)
4(15) + 8
60 + 8
68
68 = (4y + 8)

Check:
68 + 78 + 34 = 180
180 = 180 ✅

Joshua has $4,200 to invest for college. If Joshua invests $4,200 for 3 years and earns $630, what is the simple interest rate?

Rama09 [41]

Answer:

The simple interest rate is 5%.

This is possible with a rate of 6%, since in this case, his amount earned will be $5,208.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

$T = E + P$

Joshua has $4,200 to invest for college. If Joshua invests $4,200 for 3 years and earns $630, what is the simple interest rate?

We have that $P = 4200, E = 630, t = 3$ . We have to find I.

$E = P*I*t$

$630 = 4200*I*3$

$I = \frac{630}{4200*3}$

$I = 0.05$

The simple interest rate is 5%.

Joshua’s goal is to have $5,000 after 4 years. Is this possible if he invests with a rate of return of 6%?

We have to find T when $P = 4200, t = 4, I = 0.06$

$E = P*I*t$

$E = 4200*0.06*4$

$E = 1008$

$T = E + P = 4200 + 1008 = 5208$

This is possible with a rate of 6%, since in this case, his amount earned will be $5,208.

Please someone explain the question and explain the answers probably

Taya2010 [7]

Okay so all you are doing is filling out the char to do this you fine the increasing rate or the pattern. so 2*3=6 5*3=15 so the pattern is that you are multiplying every input by 3 so 0*3=0
1*3=3
3*3=9
4*3=12
then to fine the differences you just simply write how much you increased or decreased so every difference for this chart will be +3 hope this helped you have an amazing day!!!!

Find the 15th term of the geometric sequence 4, 8, 16, ...4,8,16,...

AfilCa [17]

Answer:

Step-by-step explanation:

Tn = ar^(n-1)

a = 4, r = 8/4 = 2 for n = 15

T15 = 4 × 2^(15-1)

= 4 × 2^14

= 4 × 16384

= 65536
