What is Function?A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.
The given function is,
f(t) = -16t² + 8t
This represents the height y (in feet) of a grasshopper jumping straight up from the ground t seconds after the start of the jump.
We have to calculate the time t when f(t) = 1 foot.
-16t² + 8t = 1
-16t² + 8t - 1 = 0
This is a quadratic equation.
Solve using quadratic formula.
Discriminant = [tex]\sqrt{8^2-(4*-16*-1)}[/tex] = 0
t = (-8 ± 0) / (2 × -16) = -8/-32 = 0.25
Hence the time is 0.25 seconds when the grasshopper is at 1 foot.
Hence the grasshopper will be at 1 foot from the ground in 0.25 seconds.

Three side lengths of 5.2 cm, 6.3 cm and 10.5 cm will form exactly one unique triangle.
O True
O False
True, the three sides will form exactly one unique triangle.
What is a triangle?A triangle is three dimensional shape, whose third length is less than the sum of the first and second length.
let the first length = alet the second length = blet the third length = k(b - a) < k < (b + a)
(6.3 cm - 5.2 cm) < k (6.3 cm + 5.2 cm)
1.1 cm < k < 11.5 cm
The third length = 10.5 cm which is greater than 1.1 cm and less than 11.5 cm.
Thus, the three sides will form exactly one unique triangle.

which pair of ratios will make a proportion ?
Answer:
B. 3/5 and 9/15
Step-by-step explanation:
When looking for a proportion, you must look at a ratio that equals the same like:
1/2 = 2/4
You could see that I would just have to multiply or divide the numbers by 2.
So, that means they doubled.
3/5 = 9/15
How would you get 9 from 3? You would multiply by 3 to get 9.
Therefore, to check if it is a proportion, multiply with the same number you used to multiply the first number, which would be 3.
5 × 3 = 15.
Since 15 is written in the ratio, B would be the correct answer.
Therefore, B is the Correct Answer.

A movie which ended at 8:15 p. M. Lasted for 3 hours and 40 minutes. At what time did the movie begin
Answer:4:35pm!
Step-by-step explanation:
Answer:
4:35 pm
Step-by-step explanation:
We are given the time that a movie ends, the duration of the movie, and we are asked to find the start time. Therefore, we just need to subtract the duration from the end time, and we'll have the start time.
First, we subtract the 3 hours from 8:15 pm, and that is 5:15.
*Remember that the minutes counter resets at 60*
Then we just subtract the 40 minutes, which means we end at 4:35.

Melanie is looking for a loan. She is willing to pay no more than an effective rate of 9. 955% annually. Which, if any, of the following loans meet Melanie’s criteria? Loan A: 9. 265% nominal rate, compounded weekly Loan B: 9. 442% nominal rate, compounded monthly Loan C: 9. 719% nominal rate, compounded quarterly a. B only b. A and C c. A and B d. None of these fit Melanie’s criteria. Please select the best answer from the choices provided A B C D.
Melanie should take A and B, being r(loan a)= 9.699% annually, r(loan b)=9.862% annual
What options Melanie should choose for the best deal?It is given that
Loan A: 9.265% nominal rate, compounded weekly
In order to find the easiest effective rate, we need to divide this rate by 52 (which are the weeks in a year). Once we do that, we convert this effective weekly rate into an effective annual rate. Let´s walk you through all this.
[tex]r(Eweek)=\dfrac{0.09265}{52} =0.00178173[/tex]
Or 0.178173% effective weekly. Now we can transform it into an effective annual rate.
[tex]r(e,a)=1+(r(e.week))^{52} -1[/tex]
[tex]r(e,a)=1+(0.00178173)^{52} -1=0.09699[/tex]
Or 9.669% annual, which is less than 9.955%, so this one is selected, let´s check the next.
Loan B: 9.442% nominal rate, compounded monthly
Just like we did with Loan A, we need to divide this rate too, only this time, we will divide by 12, therefore obtaining an effective monthly rate.
[tex]r(Emonth)=\dfrac{0.09442}{12} =0.00786833[/tex]
Or 0.786833% effective monthly, let´s turn it into an effective annual rate.
[tex]r(e,a)=1+(r(e.month))^{12} -1[/tex]
[tex]r(e,a)=1+(0.00786833))^{12} -1=0.09862[/tex]
Or 9.862% annual, so this rate would work for Melanie too. This means that option C) is the answer we are looking for but, let´s walk that extra mile and turn that Loan C rate into an annual rate.
[tex]r(Eweek)=\dfrac{0.09719}{4} =0.0242975[/tex]
or 2.42975% effective quarterly, now, let´s convert it into an effective annual rate.
[tex]r(e,a)=1+(0.0 242975))^{12} -1=0.010079[/tex]
That is 10.079% effective annual, therefore, Loan C is not an option for Melanie.
Thus Melanie should take A and B, being r(loan a)= 9.699% annually, r(loan b)=9.862% annual
