Answer:

5(3w+13)

Step-by-step explanation:

1) Prime factorization of 65 and 15 will give us 5 as is Greatest Common Factor

65|5

13|13

1

15|5

3|3

1

2

2) Placing the common factor outside the parentheses. And inside the sum of its quotients.

\frac{65}{5}=13\\\frac{15w}{5}=3w\\

There you have, a simplified expression:

5(3w+13)

Tasha invests $5,000 annually at 6% and an additional $5,000 annually at 8%. Thomas invests $10,000 annually at 7%. Which statem
Setler79 [48]

Answer:

B is correct.

Step-by-step explanation:

Compound Interest Formula:

V(t)=P(1+\frac{r}{n})^{nt}

Tasha invests in two ways

Case 1:

  • Principal P=$5,000
  • Rate of Interest r=0.06
  • Time t=t
  • n=1

V(t)=5000(1+0.06)^t

V(t)=5000(1.06)^t

Case 2:

  • Principal P=$5,000
  • Rate of Interest r=0.08
  • Time t=1
  • n=1

V(t)=5000(1+0.08)^t

V(t)=5000(1.08)^t

Total amount yield by Tasha = 5000[(1.06)^t+(1.08)^t]

Thomas Investment

  • Principal P=$10,000
  • Rate r= 0.07
  • t=t
  • n=1

Total amount yield by Thomas = 10000(1.07)^t

Now we make table for Tasha and Thomas different value of t

    t                  Tasha                  Thomas

   1                  $10,700                 $10,700  

   2                 $11,450                  $11,449

   3                 $12,254                 $12,250

   4                 $13,115                  $13,108

In table we can see Tasha investment will yield more from Thomas.

Thus, Tasha’s investment will yield more over many years because the amount invested at 8% causes the overall total to increase faster.

Solve for x.<br><br> −5(x−4)=−30<br><br> Enter your answer in the box.
saveliy_v [14]
First divide both sides by - 5,

x - 4 = 6

Move the constant to the right side of the equation and change its sign (-4 => +4)

x = 6 + 4

Add the numbers,

x = 10

Which of the following is true for f(x) = –2sin(x) – 3?
Finger [1]

Answer: Option C is correct!

Step-by-step explanation:

The range of function is [-1,-5]  . so first option is incorrect.

Since graph of the function f(x)=-2sin(x) is shifted down by 3 because of -3

therefore  option B is incorrect.

Period of the given function is 2pi because here b =1 and period of sinx function is given by \frac{2\pi }{b} therefore option  D is also incorrect

Period of the function f(x) is always  absolute value number in front  of sinx  which is given to be  2 here therefore option C is correct.!
