Answer:
Well if you have -4 and want to get to -1 you can add +3 to -4 to get -1
Step-by-step explanation:
Answer:
Umm. I believe this is a answer 27.2 sorry dude I will tell an expert to check this out just wait 2-3 min
Ughhh...the limit formula...this should be thrown in the trash the minute you start doing derivatives :P
(-8-9(t+d)-(-8-9t))/(t+d-t)
(-8-9t-9d+8+9t)/d
-9d/d (which is -9 for any value of d as well as when d approaches zero)
-9
So the instantaneous velocity is regardless of t or delta t
Answer:
94 cm^2
Step-by-step explanation:
The surface area of a rectangular prism can be found using:
A=2(wl+hl+hw)
We know the width is 3, the height is 5, and the length is 4. We can substitute 3 in for w, 5 in for h, and 4 in for l.
A=2((3*4)+(5*4)+(5*3))
Multiply 3 and 4
A=2(12+(5*4)+(5*3))
Multiply 5 and 4
A=2(12+20+(5*3))
Multiply 5 and 3
A=2(12+20+15)
Add 12 and 20 and 15
A=2(47)
Multiply 2 and 47
A=94
So, the the surface area is 94 cm^2
Answer:
A. (9, –36)
Step-by-step explanation:
The equations are given as:
i) y = -3x - 9
ii) y= 1/3 x - 39
Use equation i) in equation ii)
-3x - 9 = 1/3 x - 39 -------multiply each term by 3 to remove the fraction
-9 x - 27 = x - 117
collect like terms
-9 x- x = -117 + 27
-10 x = -90
10x = 90
x = 90 / 10
x = 9 ------------iii
Use equation iii in i
y = -3x - 9
y = -3 * 9 - 9
y= -27 - 9
y= -36
Hence,
x = 9 , y = -36
