beks73 [17]

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)

If the rate of inflation is 3.4%per year, the future price pt(in dollars) of a certain item can be modeled by the following expo

Doss [256]

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

$p(t)=3000(1.034)^t$

where, t is the number of years from today.

Substitute t=0 to find the current price.

$p(0)=3000(1.034)^0=3000$

Therefore the current price is $3000.

Substitute t=9 to find the price after 9 years from today.

$p(9)=3000(1.034)^9$

$p(9)=3000(1.35109177087)$

$p(9)=4053.27531261$

$p(9)\approx 4054$

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

3. The sum of three consecutive integers is 1,623.

TiliK225 [7]

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
