Identify the initial amount a and the rate of decay r (as a percent) of the exponential function h (t) = 1250(0.865)'. Evaluate the
function when t 3. Round your answer to the nearest tenth.

Answers

Answer:

809.0

Step-by-step explanation:

Given the exponential function h (t) = 1250(0.865)^t

When t = 3

h(3) = 1250(0.865)^3

h(3) = 1250 (0.6472)

h(3) = 809.0

Hence the value to the nearest tenth is 809.0

Answer:

Step-by-step explanation:

We know that 1/2 are apples and 1/3 are bananas

we also know that

apples+bananas+oranges=1

Which means that

1/2+1/3+oranges=1

Add 1/2 + 1/3 by getting the denominators equal

3/6+2/6=5/6

Which means that 5/6+oranges=1

1-5/6=1/6

1/6

write everything below this

1/2+1/3+oranges=1

1/2+1/3=5/6

5/6+oranges=1

Find the slope. Make sure to reduce.

Answers

Answer:

The slope here is undefined.

Step-by-step explanation:

The two points shown here are (4, 0) and (4, 1). To find the slope do (y B −  y A) /(x B −  x A).

(1 - 0)/(4 - 4)

Any number subtracted by 0 gets you itself. Any number subtracted byt he same number gets you zero.

1/0

You can't divide by zero, so the slope is undefined.
