What term should be added to y2-14y to make it a perfect square trinomial?

Ksju [112]

Answer:

Step-by-step explanation:

Given the monomial y²-14y, in order to make the binomial a perfect square, we need to add a constant to the function using completing the square method.

To get the constant, we will multiply the coefficient of y by 1/2 and then square the resulting value.

- The coefficient of y is -14.

multiplying the coefficient of y by 1/2 will give -14/2 = -7

- squaring -7 will result in (-7)²

= 49

The constant that will be added to the binomial to make it a perfect square trinomial is 49

Which angle is an x-intercept for the function y = cos(1) A.0 B.2 C. £ D. 2£

noname [10]

Answer: C. $\pi$

=======================================================

Explanation:

The x intercept always occurs when y = 0.

Use the unit circle to determine that $\cos(\theta) = 0$ when $\theta = \frac{\pi}{2} \text{ and } \theta = \frac{3\pi}{2}$

So if $x = \pi$ , then we have

$y = \cos\left(\frac{1}{2}x\right)\\\\y = \cos\left(\frac{x}{2}\right)\\\\y = \cos\left(\frac{\pi}{2}\right)\\\\y = 0\\\\$

which shows us that $(\pi, 0)$ is the location of one of the infinitely many x intercepts for this function.

To celebrate the first day of winter, Lin was putting stickers on some of the lockers. There are 100 lockers along one side of h

loris [4]

Answer:

24, 48, 72, 96

Step-by-step explanation:

Least Common Multiple (LCM)

It's the smallest positive number that is a multiple of two or more numbers. For example, let's find the LCM of 15 and 25:

Multiples of 15: 15,30,45,60,75,90,...

Multiples of 25: 25,50,75,100,...

Note 75 is a common multiple of both and is also the smallest possible.

Lin puts a snowflake sticker every 6 lockers and a snowman sticker every 8 lockers. To find the lockers where both stickers are places, we must find the LCM of 6 and 8:

6 = 2*3

8 = 2*2*2

Multiplying the common factors the maximum number of times it appears:

LCM = 2*2*2*3 = 24

Thus, every 24 lockers there are two stickers until Lin reaches the last 100th locker along the halfway.

The sequence of lockers is:

24, 48, 72, 96
