A parabolic heater has a cross section modeled by a parabola with vertex (0,0\right) and focus (2,0\right) . The heater has a depth of 5 inches. What is the width of the parabolic heater at its widest point? Round your answer to the nearest hundredth.
Answers
Answer:
y = 6.93
Step-by-step explanation:
Given the Vertex and ficuas of a parabola as :
Vertex (0,0) ; focus(0,2) ; depth = 5 inches
Width of parabolic heater at its widest point :
General equation of a parabola:
4p(x - h) = (y - k)²
(h, k) = Vertex
hence,
h =0 ; k = 0 ; p = 2 ; x = 5
(y - k)² = 4p(x - h)
(y - 0)² = 4*2(6 - 0)
(y-0)(y-0) = 8(6 - 0)
y² = 48 - 0
y² = 48
y = 6.928
y = 6.93

Solve the following equation.
X + 5 = 2x
Can some explain to me how to do this? I have to add one of these numbers to both sides of the equation but idk which one.
Answers
Answer:
x = 5
Step-by-step explanation:
Subtract x from both sides.
Your equation would look like this now:
5 = 1x
Divide both sides by 1.
x = 5
Hope you understand :)
Please consider Brainliest :)
[tex]x + 5 = 2x[/tex]
[tex]5 = 2x - x[/tex]
[tex]5 = 1x[/tex]
[tex]x = 5[/tex]
Let us check whether or not we have found out the correct value of x , by placing 5 in the place of x .
Which means :-
5 + 5 = 2 × 5
10 = 10
LHS = RHSHence proved that the value of x = 5 .
Therefore , 5 + 5 = 2 × 5 , ( x = 5 ) .

Step-by-step explanation:
(question asked for midpoint so my bad if this isnt what you wanted)
to calculate the median of a vector, you would have to do a simple calculation to get the answer
for the x coordinate, (9 + 17) / 2 would be 13
for the y coordinate, 5 + 4 / 2 would be 4.5
combining those would give you the answer (13, 4.5)
There are 15 circles and 12 squares. What is the simplest ratio of squares to total shapes?
Answers
They both divide by 3 so 12 divided by 3 is 4 and 15 divided by 3 is 5
The simplest ratio of squares to total shapes is 4 : 9.
The question wants the ratio to the total number of shapes so first find the total number of shapes:
= Circles + squares
= 15 + 12
= 27 shapes
There are 12 squares and 27 shapes. The ratio is therefore:
= 12 : 27
Use the lowest common factor of both numbers to find the simplest ratio. That factor is 3:
= [tex]\frac{12}{3} : \frac{27}{3}[/tex]
= 4 : 9
