Answer: f 500 Ft./sec
Step-by-step explanation:
By evaluating the derivate of the distance in t = 10s, we will see that at t = 10s the distance is changing at a rate of 464.2 ft/s
We can think of the situation as in a right triangle, one cathetus is equal to 2000ft, and the other cathetus increases at a rate of 500ft/sec.
The hypotenuse would be the distance between the radar and the rocket.
Then the distance function is:
[tex]D(t) = \sqrt{(2000ft)^2 + (500ft/s*t)^2}[/tex]
Now we need to get the rate of change, this is given by:
[tex]\frac{dD(t)}{dt} = (1/2)*\frac{2*(500ft)^2*t}{\sqrt{(2000ft)^2 + (500ft/s*t)^2} }[/tex]
Now we evaluate this in t = 10s to get:
[tex]\frac{dD(10s)}{dt} = (1/2)*\frac{2*(500ft/s)^2*10s}{\sqrt{(2000ft)^2 + (500ft/s*10s)^2} } = 464.2 ft/s[/tex]

The area of a rectangle is 3/4 square yards. If the width of the rectangle is 3/5, what is the length?
JUST TELL ME HOW TO FIND THE ANSWER
Answer:
Divide 3/4 by 3/5 to get 1 1/4.
Step-by-step explanation:
To find area, you multiply the length by the width. However, they gave you the area and the width. Therefore, you divide the width by the area (I think).
3/4 divided by 3/5 = 1 1/4
The length is 1 1/4.

Savannah is deciding between two parking garages. Garage A charges an initial fee of $9 to park plus $1.50 per hour. Garage B charges an initial fee of $4 to park plus $2.50 per hour. Let A A represent the amount Garage A would charge if Savannah parks for t t hours, and let B B represent the amount Garage B would charge if Savannah parks for t t hours. Graph each function and determine which garage would be cheaper if Savannah needs to park for 6 hours.
Answer:
A = 10 + 3t
B = 3 + 4t
if t = 12 , then A = 10 + 3(12) = $46, B = 3 + 4(12) = $51.
So Garage A is cheaper for 12 hours

Jared’s average daily balance for last month was $560. The finance charge was $8.12.
a. What was the monthly percentage rate?
b. What was the APR?
Answer:
A) monthly percentage rate = 1.45%
B) APR = 17.4%
The monthly percentage rate was 1.45 % and the annual percentage rate was 17.4%.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
We have been given that Jared’s average daily balance for last month was $560. The finance charge was $8.12.
We have to determine the monthly percentage rate.
The monthly percentage rate is the percentage ratio of the finance charge to the average daily balance.
The monthly percentage rate = finance charge / average daily balance
The monthly percentage rate = $8.12 / $560 × 100
The monthly percentage rate = 0.0145 × 100
The monthly percentage rate = 1.45 %
The Annual percentage rate = 12 × monthly percentage rate
The Annual percentage rate = 12 × 1.45 %
The Annual percentage rate = 17.4 %
Therefore, the monthly percentage rate was 1.45 % and the annual percentage rate was 17.4%.

Four glasses of milk and 3 snack bars have a total of 96 carbohydrates (carbs), and 2 glasses of milk and 4 snack bars have
many carbs are in one glass of milk and in one snack bar,
total of 78 carbs. Determine how many carbs are in one glass of milk
Answer:
Each snack bar contains 12 carbs and each milk contains 15 carbs.
Step-by-step explanation:
Let M be the carbs in milk and S the carbs in a snack bar.
We are told:
4M + 3S = 96, and
2M + 4S = 78
===
We can eliminate one of the variables and then solve for the other. Let's multiply the second equation by -2 and then add it to the first. This will eliminate the M:
4M + 3S = 96
-4M - 8S = -156
-5S = - 60
S = 12
Each snack bar has 12 carbs. Use either equation to find M. I'll use the second:
====
2M + 4S = 78
2M + 4*(12) = 78
2M + 48 = 78
2M = 30
M = 15
Each milk contains 15 carbs

what is the greatest number of relative maximum that a polynomial of degree 15 can have? Select the right answer among them 1. 14 2. 6 3. 9 4. 7 5. 4
Answer:
7
Step-by-step explanation:
The greatest number of relative maxima it can have is 14.
So, the correct answer would be option (1) 14.
Use the concept of a polynomial defined as:
An expression that consists of exponents, variables, and constants and that is combining many different mathematical procedures:
Addition, subtraction, and multiplication is referred to as polynomial.
Given that,
The degree of polynomial = 15
The objective of this question determine the number of relative maxima it can have.
The number of relative maxima that a polynomial can have is equal to its degree minus 1.
In this case:
The polynomial is of degree = 15,
Hence,
The greatest number of relative maxima it can have is 15 - 1 = 14.
So, the correct answer would be option (1) 14.

Solution:
Given,
tan2θ = 1 – e2
sec θ + tan3θ cosec θ
= sec θ + (sin3θ/cos3θ) (1/sin θ)
= sec θ + tan2θ sec θ
= sec θ(1 + tan2θ)
= √(1 + tan2θ) (1 + tan2θ)
= (1 + tan2θ)3/2
= (1 + 1 – e2)3/2
= (2 – e2)3/2
