An equation for annealing soda-lime glass is y(t)=−14t+500 , where t is time in minutes and y is the temperature of the glass in ˚C.
To find the y intercept , we plug in 0 for t
y intercept is the value , where time is 0 minutes
so we plug in 0 for t and find out y(0)
y(t)=−14t+500
y(0)=−14(0)+500 = 500
When t=0 , the value of y = 500
So , y intercept is (0,500)
Answer:
The current price is $3000 and price after 9 years from today is $4054.
Step-by-step explanation:
The future price pt(in dollars) of a certain item can be modeled by the following exponential function

where, t is the number of years from today.
Substitute t=0 to find the current price.

Therefore the current price is $3000.
Substitute t=9 to find the price after 9 years from today.




Therefore the price after 9 years from today is $4054.

Step-by-step explanation:
Answer:
540, 541, 542
Step-by-step explanation:
let the number be n
hence the 3 consecutive numbers may be expressed as:
n , n+1, n+2
it is given that the sum of the 3 numbers is 1623
hence,
n + (n+1) + (n+2) = 1623
n + n + 1 + n + 2 = 1623
3n + 3 = 1623
3n = 1623 -3
3n = 1620
n = 1620 / 3
n = 540
hence the numbers are
540, (540 + 1) , (540 + 2)
or
540, 541, 542
