I think the answer is 10 seconds, because 50+10=60/2=30. I'm not sure if that's right tho
Answer:
5.8/8=0.725
Rounded number: 0.7
Step-by-step explanation:
Estimate 6/8=0.75
6 because 5.8 rounded to a whole number=6
Answer:
given below
Step-by-step explanation:
−2x + 5y > 15
5y > 15 + 2x
if x is 0 then y is 3 and its greater than so increasing
therefore answer is graph A
Answer:
152
Step-by-step explanation:
All segments in a triangle add to 180. 1
8+10+x=180
x=152
Step 1: Find f'(x):
f'(x) = -6x^2 + 6x
Step 2: Evaluate f'(2) to find the slope of the tangent line at x=2:
f'(2) = -6(2)^2 + 6(2) = -24 + 12 = -12
Step 3: Find f(2), so you have a point on y=f(x):
f(2) = -2·(2)^3 + 3·(2)^2 = -16 + 12 = -4
So, you have the point (2,-4) and the slope of -12.
Step 4: Find the equation of your tangent line:
Using point-slope form you'd have: y + 4 = -12 (x - 2)
That is the equation of the tangent line.
If your teacher is picky and wants slope-intercept, solve that for y to get:
y = -12 x + 20
