Answer:
k=16
Step-by-step explanation:
So the tangent line is
and it tangent to function
Since the slope of the tangent line is 4, this means the derivative of f(x) is 4 but first let find the derivative of
Use the Sum Rule,
Use the Power Rule and we get
Set this equal to 4
So at x=-2, the slope of the tangent line is 4.
Plug -2 in the orginal function, and we get
So the point must pass through -2,8 with a slope of 4.
So the value of k is 16.
Answer:
The equation of the line is x = 2
Answer:
a.9
b. ay=9
xy= 18
Step-by-step explanation:
a. xa=ay (since a is a midpoint that means xa and ay are the same amount).
3x=5x-6
subtract 5x from both sides
-2x=-6
inverse operations, so divide both sides by -2. (a negative divided by a negative is a positive)
x=3
so xa=3x. fill in x
3*3 is 9
b. fill in the x
5*3-6
5 times 3 is 15.
15-6=9
(also xa is 9 and they are congruent so both are 9)
ay= 9
add both sides to find xy
9+9=18
xy=18
F.
Step-by-step explanation:
sorry i gusstn guesst it
V (cone) = (1÷3) × (r×r×h) л cm3
3 cone = 1 cylinder (if "h" and "r" is same)
There is two cone...
1st one: (1÷3) × 3×3×5 л cm3 = 15л cm3
2nd one: (1÷3) × 3×3×8 л cm3 = 24л cm3
15 + 24 = 39л cm3
