Answer: y = 5/6x - 2

Step-by-step explanation:

Y =mx + b

Step 1 find slope also known as m:

Y2 - y1 / x2 - x1

3-(-7)/6-(-6) = 10/12 can be reduced to 5/6

Step 2 find b:

3 = 5/6 (6) + b

3 = 30/6 + b

3 = 5 + b

-5 - 5

-2 = b

Step 3 write equation:

Y = 5/6x - 2

The graph of a quadratic function f(x) intersects the x-axis At -3 and 5. Create a function that would produce these results.

FinnZ [79.3K]

Answer:

f(x) = x² - 2x - 15

Step-by-step explanation:

∵ The function intersect x-axis at -3 and 5

∴ f(x) = 0 at x = -3 , 5

∵ The form of the quadratic equation is ⇒ ax² + -b/a x + c/a = 0

ax² - b/a x + c/a = 0

Where the sum of its roots is b/a and their multiplication is c/a

∵ a = 1

∵ -3 , 5 are the roots of the quadratic equation

∴ b = -3 + 5 = 2

∴ c = -3 × 5 = -15

∴ f(x) = x² - 2x - 15

HELP ME PLS ITS BEEN AN HOUR LUV U GUYS <33

Answer:

19.6 cubic centimeters

Step-by-step explanation:

The ratio of two similar 3D figures' volumes is equivalent to the ratio of their corresponding lengths (whether it's width, height, length, radius, etc) cubed.

Here, we know the cones are similar, and we know the smaller radius is 2 and the larger radius is 3. Then the ratio of the volume of the smaller one to the volume of the larger one is $(2/3)^3=8/27$ .
