Answer:
k=20.
Explanation: First we find where f(x) has its local extrema: f'(x)=3x2−10x+3. The critical points are roots of the equation: 3x2−10x+3=0.
Multiplying both sides of this equation by 3, to eliminate the fraction, we get:
9 + m = 6.
Next, we subtract 9 from both sides to isolate m: m = 6 - 9 = -3
Then m = -3.
Check: Subst. -3 for m in this equation:
9 - 3 6
------- = ------ = 2 (as expected). Thus, m = -3 is correct.
3 3
Problem #10:
4n - 9 = -9 Add 9 to both sides: 4n = -9 + 9 = 0.
Divide both sides by 4: n = 0.
Check: Substitute 0 for n: 4(0) - 9 = -9 is true.
Answer:
y = 41
x = 64
Step-by-step explanation:
7y + 2x - 10y + 3x² - 10x
3x² - 10x + 2x + 7y - 10y
3x² - 8x - 3y
Write the equation of the circle with center (3, 2) and radius r = 7. Use the ^ key for the exponents. Write your answer as the example:
(x - 4)^2+(y+8)^2=25
