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.
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.
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 ) .

Answer:
D, (13, 4.5)
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)

Wendy was traveling from Baltimore, MD to Cleveland, OH. For the first 2 3/4 hours of her trip, she drove an estimated 63 mph. For the second portion of her trip, which took her 3 1/2 hours, she drove at an estimated rate of 57 mph. Write an expression to model her distance and calculate how far she drove. You may use the distance formula d=r*t (distance = rate * time).
Answer: D = r*t + r*t 372 3/4 = (63 * 2 3/4) + (57 * 3 1/2)
OR
D1 + D2 = Total 173 1/4 + 199 1/2 = 372 3/4
D1 = r1 *t1 63 * 2 3/4 = 173 1/4
D2 = r2 * t2 57 * 3 1/2 = 199 1/2
Step-by-step explanation:
The trip is in two segments, so calculate the distance driven in each portion, then add the two distances together to get the total.
Another way to write the expression would be D = r*t + r*t
The total distance that Wendy drove to Cleveland will be 372.75 miles.
For the first 2 3/4 hours of her trip, she drove an estimated 63 mph. Then, the distance traveled will be:
= 63 × 2 3/4
= 173.25 miles.
For the second portion of her trip, which took her 3 1/2 hours, she drove at an estimated rate of 57 mph, the distance will be:
= 57 × 3 1/2
= 199.5 miles
The total distance traveled will then be:
= 173.25 miles + 199.5 miles
= 372.75 miles.
