465 -(-45) = x
This creates a double negative which becomes a positive and you solution would be 465+45 =X, X = 510
First: work out the difference (decrease) between the two numbers you are comparing. Then divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number, then this is a percentage increase. :)
Answer:
First one, second one, fourth one, and last one
Step-by-step explanation:
Answer:
A. ~14.3 B. ~9.93
Step-by-step explanation:
A.
By looking at the equation you can see that you need to find the tan of the angle so the equation will be "Tan 40= 12/x" which you can simplify to "X=12/Tan 40" which equals "about 14.3"
B.
This one is very similar
By looking at the equation you can see that you need to find the Cos of the angle so the equation will be "Cos 25= 9/x" which you can simplify to "X=9/Cos 25" which equals "about 9.93"
From the given information, the parabola is a sideways parabola facing left with vertex at the origin.
Required equation is (y - 0)^2 = 4p(x - 0)
y^2 = 4px
But 0 + p = -8 => p = -8
Therefore, required equation is y^2 = 4(-8)x
y^2 = -32x
