Answer:
The question to your answer is:
a) cos 150 = -√3 / 2 or - 0.866
b) tan 225 = 1
c) cos (-240) = -1/2
Step-by-step explanation:
See the picture below
180/3=60
Now lets find out what x is the get 5x+10 to equal 60.
Just looking at it, its D.....x=10
5(10)+10
50+10=60

Answer:
Step-by-step explanation:
Let's just check something out before we continue to fill in the blanks.
The zeros are (x - 1) and (x -5)
y = (x - 1)(x - 5) Remove the brackets.
y = x^2 - 6x + 5 Complete the square
y = (x^2 - 6x + 9) + 5 - 9
y = (x - 3)^2 - 4
So we have a minumum at (3, - 4) Now we can go through the rest of the questions.
Part A
(1,0) and (5,0)
Part B
The vertex is (3, - 4) See the completed square above.
Part C
It's a minimum. It is the point between the two roots on the x axis. The vertex drops below the x axis.
Part D
The axis of symmetry goes through the x value of the minimum.
x = 3
The answers are all in parts A B C D. I leave you to figure out where to put them. You should be able to do that.
The answer is 180ft squared. I got this when I used the formula 1/2 times base times height
equation 1/2 timed 20 times 18
- u can divide half of 20 or 18
10 times 18 = 180
Answer:
-4
Step-by-step explanation:
a = 3
b = -4
c = -2
2a + 3b - c
= 2(3) + 3(-4) - (-2)
= 6 + (-12) + 2
= -4
