Part A: $1920 because if you change 20%to .2 then .2*1600= 320 and 320+1600=1920
Part B: $320 because 1600/5=320 that is after taxes, before taxes it is $384 because 1920/5=384 you divided it by 5 because it is 1/5, so you divide it by 5 and then multiply it by 1 because 1/5=y/1600 so find y which is what he out in the savings account
Answer:
(a) dy/dt = 68 - 3.72t
(b) 64.28m/s
Step-by-step explanation:
Given y = 68t - 1.86t²
Average Speed is rate of chance of distance with respect to time. Written as dy/dt
To obtain dy/dt, we differentiate y with respect to t, doing that, we have
dy/dt = 68 - 2(1.86)t
= 68 - 3.72t
(a) dy/dt = 68 - 3.72t
(b) To estimate the speed when t = 1, we substitute t = 1 in dy/dt .
dy/dt at t = 1 is
68 - 3.72(1)
= 68 - 3.72
= 64.28
The speed at t = 1 is 64.28m/s
Answer:
$1440
Step-by-step explanation:
First, find the unit rate by dividing 300 by 5, which equals 60. So, Kendra earns $60 in one day. Then, multiply 60 by 24, which equals 1440. So, Kendra makes $1440 in 24 days. Hope this helped!
Answer:
(-4,-1) is the answer unless your asking for an actual equation
Answer:
To find the circumference of a circle, your equation is 2*pi*radius
C=2*3.14*2 (radius is half of diameter so 4/2=2, 2=radius)
C=12.56 ft
To find the area of a circle, your equation would be pie*r^2
A=3.14*2^2
A=3.14*4
A=12.56 sq. ft
Hope this helps ;)
