17. Which of the following is a factor of both x^2 - x - 6 and x^2- 5x+6?
andreyandreev [35.5K]

Step-by-step explanation:

For the equation x^{2} - x - 6, factoring gives us the following:

(x - 3)(x + 2)

For the equation x^{2} - 5x + 6, factoring gives us the following:

(x - 3)(x - 2)

From this, we see that the common factor is (x - 3)

Larry wants to buy some carpeting for his living room. The leangth of the room is 3 times the width and the total area of the ro
ioda
Equation for length:
l = 3w

l × w = 12

Substitute 3w into L.
(3w) × w = 12
4w = 12
w = 3

Substitute 3 into w to find the length.
l = 3w
l = 3×3
l = 9

The width is 3 and the length is 9.

Please help solve this, I’ve tried my best. My answers are a height of 6.7 using 30-60-90 as a last resort, and the glass volume
Neko [114]

Answer:

A) To ensure the correct and exact straight height

B) 15 inches

C) 24.87 in^{3}

Step-by-step explanation:

Hello! Lets start!

First, it asks us to explain why the two bases must be parallel. In order to measure the correct and exact height, we must be sure that the bases are parallel, or else there would be a range of heights; in order to ensure that you are measuring a straight distance, they must be parallel!

Second, it asks us to identify the height of cone. To do this, we must make a slope! We can see that, for every time we go down 5 inches, we lose 1 inch of our base! Our slope in this situation would be -5. So, lets continue to see how long before the cone reaches its tip, in which the base would be equal to 0. At 5 inches, our base is 2 inches. At 10 inches, our base is 1 inch. At 15 inches, we do not have a base, as it equals 0! So therefore, our cone height is 15 inches.

Third, it asks us to identify the volume of the cup, which is also called a <em>circular truncated cone. </em>To do so, we can use the formula:

₁V = \frac{1}{3} \pi (r_{1}^2 + r_{1}r_{2} + r_2^2)h

Lets plug in our information!

V = \frac{1}{3} \pi (1.5^{2} + (1.5)(1) + 1^{2}) (5)\\V = 24.87

Hope this helps! Remember, math is fun!
