The parent function is y = x^2

Shifting this graph down five units leads to the graph of y = x^2 - 5

a car rental company charges an initial fee plus a constant fee per kilometer driven this table compares a total distance driven

ollegr [7]

Answer:

$120

Step-by-step explanation:

The initial fee that was charged is the y-intercept of the equation that represents the situation given.

Using the slope-intercept equation, y = mx + b, find m and then find b, which is the initial fee.

Where, x = distance, y = price, m = slope, and b = y-intercept, which is the initial fee that was charged that we are looking for.

First, using two pairs, (105, 183) and (140, 204), find the slope (m):

$m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{204 - 183}{140 - 105} = \frac{21}{35} = \frac{3}{5}$

m = ⅗

To find the y-intercept, b, substitute x = 105, y = 183, and m = ⅗ into $y = mx + b$ .

$183 = \frac{3}{5}(105) + b$

$183 = 63 + b$

Subtract 63 from each side

$183 - 63 = b$

$120 = b$

The initial fee of the company is $120.

The normal water level in the river is 0. Now it is 2 feet below normal.

Mademuasel [1]

The question can't be answered with the information given.

First of all, we don't know how fast the rain is falling ... how many inches
per hour.

But even of we knew that, that would only tell us how much water would
pile up in our yard or on our street. You're talking about a river, and
that's a whole different ball game.

The rain that falls right here is going to flow down the river to somewhere
else. But the rain that falls up-river from us is going to flow down to where
we are, and the river is going to rise. The amount it rises depends on . . .

-- how fast the rain is falling,
-- how much area it's falling on,
-- how much forest there is in that area and how many houses and
parking lots where the ground can't soak up the water and hold it,
-- and also on how wide the river is and how fast the water can flow through it.
