Answer: a,c,f (4^3, 8^2, 2^6)
Step-by-step explanation:
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:
(1)
With p the distance from the origin to the focus using p=6, the equation (1) of the parabola becomes:
(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:
, solving for y

Answer:
$2400
Step-by-step explanation:
60 tonnes = $1800
80 tonnes = $?
= 1800 × 80/60
= $2400
Answer: 6
Step-by-step explanation:
Let's start by getting the equation to slope intercept form
First simplify

Then get y by itself

In slope intercept form y=mx+b, m is the slope
In this case the slope is 6
