Im not so sure on the others, Gl!
The project Mary Jackson worked on at nasa soon after she was hired was landing astronauts on the moon and how to return them safely back to earth.
Using an exponential function, the inequality is given as follows:

The solution is t > 2.9, hence the tax status will change within the next 3 years.
<h3>What is an exponential function?</h3>
A decaying exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the decay rate, as a decimal.
For this problem, the parameters are given as follows:
A(0) = 9400, r = 0.143.
The population after t years is modeled by:



The tax status will change when:

Hence the inequality is:

Then:



Since both logs are negative:

t > 2.9.
The solution is t > 2.9, hence the tax status will change within the next 3 years.

Answer: You could only buy 1 pound of raisins and 1 pound of walnuts
Step-by-step explanation:
$8=1 pound of walnuts
$15-$8=$7
$4=1 pound of raisins
$7-$4=$3
$3 is not enough to buy a pound of raisins since it’s one dollar off but it is also not enough to buy a pound of walnuts because it’s off by $5
Answer:
-9
Step-by-step explanation:
The higher the negative number, the lower it goes in temperature.
-9 < -5
This makes -5 colder since -9 is a higher negative number.
Best of Luck!
