(22,11) it equals the about when you plug it in
The decay factor here is 0.85, and it means the car’s value changes by 85% every year, or goes down by 15% every year.
The formula for exponential decay is y = a(1 - b)^x
y is the final amount.
a is the initial amount, which is $30,000 in this case.
(1 - b) is the decay factor, or the number the original value gets multiplied by each year, which is 0.85 here.
b is the percent decrease in decimal form. In this case, we can find it using the formula (1 - b) = 0.85. We soon find that b = 0.15, or 15%.
x is the number of years.
Look at the graph below carefully
Observe the results of shifting ={2}^{x}f(x)=2x
vertically:
The domain, (−∞,∞) remains unchanged.
When the function is shifted up 3 units to ={2}^{x}+3g(x)=2x +3:
The y-intercept shifts up 3 units to (0,4).
The asymptote shifts up 3 units to y=3y=3.
The range becomes (3,∞).
When the function is shifted down 3 units to ={2}^{x}-3h(x)=2 x −3:
The y-intercept shifts down 3 units to (0,−2).
The asymptote also shifts down 3 units to y=-3y=−3.
The range becomes (−3,∞).
Answer:
382 children and
312 adults swam
Step-by-step explanation:
Let the number of children be x
And let the number of adult be y
Hence on a hot summer day
x +y = 694 - - - - - - - 1
x= 694-y
Also the daily prices are $ 1.25 for children and $ 2.50 for adults
1.25x + 2.50y= 1257.50-------2
Let us substitute x= 694-y in equation 2
1.25(694-y) + 2.50y =1257.50
867.5-1.25y +2.50y = 1257.50
-1.25y+2.50y= 1257.58-867.5
1.25y= 390
y= 398/1.25
y= 312
Substitute y= 312 in equation 1 to find x
x + 312= 694
x= 694-312
x= 382
Hence 382 children and
312 adults swam
I think................U do 100 = 10 because 100 is the hundreds and the tenths is the 10.
