Use the formula A(t)=P(1+[r/n])^(n)(t) which for us looks like this:
A(t)= 3000(1+[.038/4])^(4)(9). Doing that math, you have 3000(1.405489). The product of that is $4216.47
Answer:X =1
Step-by-step explanation:
Answer:since the plane desends 1,300 feet per minute it would desend 19,500 feet afetr 15 minutes (1,300 × 15 = 19,500) subtract this from the planes's initial altitude 32,000 and the new altitude will be 12,500. (32,000−19,500=122,500

Answer:
Step-by-step explanation: Hey for the second one I got y = -3/4x -0.5 I'm not sure if its correct though sorry if not
ill try my best to explain my solution though
1. From the parallel equation (3x + 4y = 12) all we need to do is find the slope
So the easiest way to do so is to put the said equation in <u>y-intercept </u>form
y=mx +b
m= slope
b= y intercept
so 1. 3x + 4y = 12
=
4y = 12-3x
divide that by 4 to get only y
y=3-3/4x
-3/4 is our slope
y=-3/4x+b
than we have a point -2, -2
if we put -2 for y
-2=-3/4x+b
and then we put our -2 for x
-2 = -3/4 * -2 + b
=
-2 = -1.5 +b
b=-0.5
Answer : y=-3/4x-0.5
