Answer: f(-3) = 278, f(-4) = 232

Step-by-step explanation:

f(x) = 4x³ - 6x² - 144x + 8

f(-3) = 4(-3)³ - 6(-3)² - 144(-3) + 8

f(-3) = 4(-27) - 6(9) - 144(-3) + 8

f(-3) = 278

f(-4) = 4(-4)³ - 6(-4)² - 144(-4) + 8

f(-4) = 4(-64) - 6(16) - 144(-4) + 8

f(-4) = 232

Answer: JG= 12.
Explantation: Since it is a parallelogram, we know that EJ and JG are congruent (equal). Therefore, we set EJ and JG as an inequality. (3w = w + 8) We solve for W and get w=4. Plug in 4 into the JG equation (4 + 8). The answer would be 12.

a spinner has 1 yellow, 2 red, 3 blue and 2 green sections. What is the probability of not getting a yellow?

guajiro [1.7K]

Hello,

spinner has 1 yellow, 2 red, 3 blue and 2 green sections. What is the probability of not getting a yellow?

to find the probability to not get a yellow you have to know the total of color which is

1+2+3+2=8

and its 1 yellow

So the probability of not getting a yellow is 1/8

hope this help

Find an equation of the tangent line to the hyperbola y = 3/x at the point (3, 1).

Vesna [10]

Let's find the derivative of that hyperbola in order to find a slope formula to help us with this equation. We already have an x and y value. The derivative is found this way: $y'= \frac{x(0)-3(1)}{x^2}$ so $y'=- \frac{3}{x^2}$ . The derivative supplies us with the slope formula we need to write the equation. Sub in the x value of 3 to find what the slope is: $y'=- \frac{3}{3^2}=- \frac{3}{9}=- \frac{1}{3}$ . So in our slope-intercept equation, x = 3, y = 1, and m = -1/3. Use these values to solve for b. $1=- \frac{1}{3}(3)+b$ so b = 2. The equation, then, for the line tangent to that hyperbola at that given point is $y=- \frac{1}{3}x+2$
