Answer:  f(t)=35400(1.02)^t

Step-by-step explanation:

The exponential growth function is given by :-

f(t)=A(1+r)^t...(i)

, where A = initial value , r= rate of growth ( in decimal) and t is time (usually in years).

Given,The population of a city is 35,400. The population is expected to grow at a rate of 2% each year.

i.e. A=  35,400

r=2%=0.02  [we divide percent by 100 to convert it into decimal]

Substitute all values in (i), we get the function represents the population of the city after t years :

f(t)=35400(1+0.02)^t\\\\f(t)=35400(1.02)^t

Sandra saves 9% of her salary for retirement this year salary was 1000 more than in her previous year and she saved $4050 what w
allochka39001 [22]

Answer:

$44,000

Step-by-step explanation:

The statement indicates that Sandra saves 9% of her salary and she saved $4,050 this year. That means that the 9% of her salary, x, is equal to $4,050. You can write the following:

x*0.09= 4,050

Now, you can isolate x to find her salary this year:

x=4,050/0.09= 45,000

Then, you have that this year salary was 1000 more than in her previous year. As you have found her salary for this year, you can subtract 1,000 from it to find her salary in the previous year:

45,000-1,000= 44,000

According to this, the answer is that her salary in the previous year was $44,000.

graph the line that passes through the points (-8,9) and (4,-3) what are the x and y intercepts for this line someone help pleas
VashaNatasha [74]

Answer:

(0,1)- y intercept (1,0) x intercept

Step-by-step explanation:

first lets write this equation in slope intercept form: y=mx+b

m=slope

b=y intercept

so

slope formula:

(y2-y1)/(x2-x1)

y2=-3

y1=9

x2=4

x1=-8

so

(-3-9)/(4--8)=-12/12=-1

slope=-1

hence

y=-1x+b

substitute "x" as 4 and "y" as -3

so

-3=-1(4)+b

-3=-4+b

1=b

so

y=-x+1

1=y intercept

and

0=-x+1

-1=-x

1=x

1=x intercept
