The cross section of a parabolic reflector has a vertical axis of symmetry with its vertex at (0,0) . The focus of the reflector

Paha777 [63]

Answer:

The depth of the reflector is 0.84 feet

Step-by-step explanation:

<em>(See the figure below)</em>

The equation of a parabola centered at the origin with an axis of symmetry on y-axis is:

$x^{2}=4py$ (1)

With p the distance from the origin to the focus using p=6, the equation (1) of the parabola becomes:

$x^{2}=4(6)y=24y$ (2)

Note that the point B is on the parabola, so this point should satisfy the parabola equation (2) that allow us to use the value x=4.5 to find the y value associated to it, that it is the depth (h) of the reflector:

$(4.5)^{2}=24y$ , solving for y

$y=\frac{(4.5)^{2}}{24}\approx0.84\,ft$

(need done quickly)

The error is that he probably forgot the decimal point thus causing him to say '"hundred" instead of "and" for the decimal point.

Circle A has center of (4, 6) and a radius of 5, and circle B has a center of (1, 0) and a radius of 15.What steps will help sho

melisa1 [442]

Answer:

Dilate circle A by a scale factor of 3.

Step-by-step explanation:

Generally, similar figures have sides in the same ratio

3(5) = 15

When dilate A by factor 3, it will look exactly like B

What is 27.773 to its nearest tenth

Olenka [21]

Check the hundredth position after the decimal point.

This = 7 so we add 1 to the tenth position so 7 becomes 7+1 = 8

Answer is 27.8 to nearest tenth
