First we write standard form that includes both vertex and focus. The formula goes like this:
(x-h)^2 = 4*p*(y-k)
h and k are coordinates of vertex. since vertex is at beginning that means that h=k=0
p is focal lenght and in our case it is 9
expressing al of this we get:
x^2 = 4*9*y
x^2 = 36y
y = 1/36 * x^2
Hello!
I believe that when you multiply 11.80 w/ 20, you'll get 236 as your Area
I hope this helps!
Answer:
t = 4
Step-by-step explanation:
13 + t = 17
t = 4
13 + 4 = 17
An easier way to solve a question like this is to subtract the number given by the answer.
Example:
17 - 13 = 4
Question 3
if 7x = 28
divide both sides by 7
7x/7 = 28/7
x = 4
This is division property of equality
Question 1
if angle m is 80 degrees the m = 80 degrees
this can be a congruent angles or alternate angles are equal
this is symmetric property of equality
Question 5
m1 = 30 and mz1 = m2, then m2 = 30
this property is transitive property of equality
Question 2
if RS - TU and TU =YP, then RS = YP
this means you can substitute RS with YP
then we have our new expression as
YP - YP
this is substitution property of equality, this is because we are substituting a function with another function
