Answer:
Option b.
Step-by-step explanation:
We can easily solve this problem by using a graphing calculator or plotting tool.
The function is
h(t) = cos (t +1)
Please, see attached picture below.
By looking at the picture, we can tell that the amplitude is equal to 1
The function has a period of T = 2π
We can see there is no vertical shift.
It has a phase shift of +1. (Which moves the graph to the left)
Answer:
Option b.
Answer:
y = 1/2x + 4
Step-by-step explanation:
If the line is perpendicular to y = -2x + 5 then the new line has a slope of 1/2.
So solve for b: using y = mx + b
2 = 1/2(-4) + b
2 = -2 + b
4 = b
Put it all together
y = 1/2x + 4

Answer: 2
1•3+1/3 divided 2/3
3+1/3 divided 2/3
4/3 divided 2/3
4/3 • 3/2
4 • 1/2
4/2

Answer:slope of line is 5/7
Explanation:The slope of the line can be calculated using the following rule:
slope =
![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By2-y1%7D%7Bx2-x1%7D%20)
The given points are:
(-9,-10) which represent (x1,y1)
(-2,-5) which represent (x2,y2)
Substitute with the points in the above equation to get the slope as follows:
slope =
![\frac{-5-(-10)}{-2-(-9)}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-5-%28-10%29%7D%7B-2-%28-9%29%7D%20)
= 5/7
