An air traffic controller is tracking two planes. To start, Plane A is at an altitude of 3500 feet and Plane B is at an altitude

MrRa [10]

3500 + 40.25s = 2768 + 55.5s
3500 - 2768 = 55.5s - 40.25s
732 = 15.25s
732 / 15.25 = s
48 = s......same at 48 seconds

3500 + 40.25(48)
3500 + 1932
5432 <== altitude

If f(x) = x ^ 2 is vertically compressed by a factor of 9 to g(x) , what is the equation of g(x) ?

Maslowich

Answer:

$g(x) = \frac{1}{9} \,x^2$ which agrees with option A in the list of possible answers

Step-by-step explanation:

A vertical compression by a factor 9 is represented by the transformation:

$\frac{1}{9} \,f(x) = \frac{1}{9} \,x^2$

Therefore the answer to the problem is:

$g(x) = \frac{1}{9} \,x^2$

I NEED ANSWER PLZ Given sets: D = {5, 6, 7, 8, 9, 10}, E = {1, 3, 5, 7, 9, 11}, F = {3, 6, 9, 12} What is D ∩ E?

Olin [163]

Answer:

answer={5,7,9}

Step-by-step explanation:

for, D∩E

we find the common numbers in both sets, which are:

D={5,6,7,8,9,10}

E={1,3,5,7,9,11}

so, D∩E={5,7,9}
