Answer:
3
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
5 is the hypotenuse, 3 is the opposite side, and 4 is the adjacent side. Thus, the cosine of A is adjacent/hypotenuse, hence 4/5.
Answer:
D
Step-by-step explanation:
Alright, so we know that they can unload 25 trucks in 5 hours.
If we do 25/5 We find out that they can unload <u>5 trucks per hour</u>
Unfortunately, that is not one of the answers, so we will have to do some investigating to find something that is <u>equivalent</u>!
After evaluating the available answers, you can find that answer D lines up with our first assumption!
Every 1/5th of an hour the Fast-Pack people can unload a truck!
We can calculate this by writing:
1/5*25=<u>5</u>
<u></u>
Please let me know if you have any confusion! :)
Answer:
y = - 1 , x = 4
Step-by-step explanation:
The equation of a horizontal line parallel to the x- axis is
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (4, - 1 ) with y- coordinate - 1 , then
y = - 1 ← equation of horizontal line
The equation of a vertical line parallel to the y- axis is
x = c
where c is the value of the x- coordinates the line passes through.
The line passes through (4, - 1 ) with x- coordinate 4 , then
x = 4 ← equation of vertical line
