Answer:
y = 1/4x - 1
Step-by-step explanation:
so the y-int is found on -1
and to find the slope, do rise/run
goes up by 1, over by 4
since the line is INCREASING, the slope is positive.
make sure you pay attention to if the line is decreasing/increasing, i forgot to in the other one. my bad
Answer:
1. <u>Average velocity</u>
When t=4
i. [4, 4.1]
= y(4.1) - y(4) / 4.1 - 4
= 275 - 16(4.1)^2 - 275 - 16(4)^2 / 0.1
= 275 - 16*16.81 - 275 - 16(16) / 0.1
= 6.04 - 19 / 0.1
= -12.96 /0.1
= -129.6
ii. [4, 4.05]
= y(4.05) - y(4) / 4.05 - 4
= 275 - 16(4.05)^2 - 275 - 16(4)^2 / 0.05
= 275 - 16*16.40 - 275 - 16(16) / 0.05
= 12.6 - 19 / 0.05
= -6.4 / 0.05
= -128
iii. [4, 4.01]
= y(4.01) - y(4) / 4.01 - 4
= 275 - 16(4.01)^2 - 275 - 16(4)^2 / 0.01
= 275 - 16*16.08 - 275 - 16(16) / 0.01
= 17.72 - 19 / 0.01
= -1.28 / 0.01
= -128
b. Instantaneous velocity
y = 275 - 16t^2
dy/dx = -32t
Considering t = 4
Instantaneous velocity after 4 seconds = -32(4)
Instantaneous velocity after 4 seconds = -128
Answer:
Step-by-step explanation:
You first do 432 divided by 9 which is 48. However, there could be multiple dimensions for the base because 48 is a composite number. One example could be 6 by 8
