Sorry this is such a terrible drawing, but it starts 2 units under the x axis, and rises 2 units and runs 7 units. The domain and range are all real numbers because this is linear.

Answer:

x=0, y=-2

M=K(t+r) solve for t

jasenka [17]

Answer:

t = (M/K)-r

Step-by-step explanation:

We want to isolate the variable t.

So, we should first divide both sides by K

M/K=(t+r)

Then, we can subtract r from both sides, giving us

(M/K)-r=t

And that's your answer

How tall is the tower?

Karo-lina-s [1.5K]

Answer:

93.6 ft

Step-by-step explanation:

$\bf \cfrac{AB}{BC} = \tan(60)$

$\bf \cfrac{x}{50} = \sqrt{50}$
$\bf x = 50 \sqrt{3}$

Length of tower:-

$\bf x + 7$
$\bf 50 \sqrt{3} + 7$
$\bf 93.6025$
$\bf = 93.6$

Therefore, the tower is 93.6ft tall.

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

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