I need help PLEASE !!!! Write a cosine function that has an amplitude of 2, a midline of 4 and a period of 4.
stiv31 [10]

Answer:

\mathbf{y = 2cos ( \dfrac{\pi}{2}(x - 0) + 4}

Step-by-step explanation:

The standardized cosine function is ;

\mathbf{y = Acos (Bx + C) +D}

Amplitude |A| = 2

Period \dfrac{2 \pi}{B }= 4

2π = 4B

B = \dfrac{2 \pi}{4}

B = \dfrac{\pi}{2}

Midline y = 4;  D = 4

Phase shift; since no phase shift is given; then C = 0

The cosine function: \mathbf{y = 2cos ( \dfrac{\pi}{2}(x - 0) + 4}

Please help i suck at these
vaieri [72.5K]

Answer:

1st Option;

j = 4.5

k = 2

Step-by-step explanation:

Let's solve for "j" first:

=> We know that by the definition of midpoint segment theorem we can say;

3j = 5j - 9

0 = 5j - 3j - 9

0 = 2j - 9

0 + 9 = 2j

9 = 2j

9/2 = j

4.5 = j

=> Now that we have j-value we use the same method to solve for k-value;

6k = k + 10

6k - k = 10

5k = 10

k = 10/5

k = 2

Therefore;

j = 4.5

k = 2

<u>So the first option would be correct!</u>

Hope this helps!
