Answer:1.2675x10^37

Step-by-step explanation:

3.9x10^33 x 3.25x10^3

3.9x3.25x10^33x10^3

12.675x10^(33+3)

12.675x10^36

1.2675x10^1x10^36

1.2675x10^(1+36)

1.2675x10^37

Write an equation for the exponential function represented in the table below.

Neko [114]

Answer:

$f(x)=-\frac{1}{2}(10^x)$

Step-by-step explanation:

Let the exponential function be $f(x)=a(b^x)$ .

When x=0, $f(0)=-\frac{1}{2}$

$-\frac{1}{2}=a(b^0)$

$a=-\frac{1}{2}$

The function now becomes $f(x)=-\frac{1}{2}(b^x)$

When x=1, f(1)=-5

This implies that:

$-5=-\frac{1}{2}(b^1)\\ \implies b=10$

Therefore the equation for the exponential function represented in the table below is $f(x)=-\frac{1}{2}(10^x)$

PLEASE HELP ME ITS MY LAST QUESTION!!

100 = 10^2

1000 = 10^3

10000 = 10^4

0.1 = 10^(-1)

0.01 = 10^(-2)

0.001 = 10^(-3)

Now,

100 × 0.1 = 10^2 × 10^(-1)

= 10

Two brothers, Mark and Walter, each inherit $20000. Mark invests his inheritance in a savings account with an annual return of 2

Igoryamba

Answer:

$720

Step-by-step explanation:

$20000 - 100%

$x. - 2.5%

x=(20000*2.5)/100=500

20000+500=$20500 in one year (Mark)

20000 - 100

x. - 6.1

x= (20000*6.1)/100 = 1220

20000+1220= $21220 (Walter)

21220-20500= $720 more (Walter will have after 1 year)
