The stopping distance, D, in feet of a car is directly proportional to the square of it's speed, V. Write the direct variation e

kow [346]

Answer:

$D=kV^2$

Step-by-step explanation:

In this problem, it is given that,

The stopping distance, D, in feet of a car is directly proportional to the square of it's speed, V.

We need to write the direct variation equation for the scenario above. It can be given by :

$D\propto V^2$

To remove the constant of proportionality, we put k.

$D=kV^2$

k is any constant

Hence, this is the required solution.

Here are 180 candies in a candy shipment. There are Gobs, Blobs, and Toffees. The bage are made in ratio of 4:2:3 of Gobs, to Bl

Maru [420]

Answer:

The answer to the cost for each toffee is given below:

Step-by-step explanation:

The computation of the cost for each toffee is shown below:

Given that

There are a total 180 candies hat includes three types in a ratio of 4:2:3

Gobs = 4 ÷ 9 × 180 = 80

Blobs = 2 ÷ 9 × 180 = 40

Toffees = 3 ÷ 9 × 180 = 60

Now the total cost of all the candies shipment is $430

So,

The equation would be

80 × $1.50 + 40 × $2.50 + 60 × per cost = $430

120 + 150 + 60 × per cost = $430

60 × per cost = $430 - $120 - $150

60 × per cost = $160

Per cost is $2.67

So for toffees it would be 160

Find the focus for y=x^2+4x-7

padilas [110]

ANSWER

$(2,-10.75)$

EXPLANATION

The given function is

$y = {x}^{2} - 4x - 7$

We rewrite this function to obtain,

$(y + 11) = {( x- 2)}^{2}$

We now compare this function to

$(y - k) = 4p {( x- h)}^{2}$

We have

$4p = 1$

This implies that,

$p = \frac{1}{4}$

The vertex is (2,-11).

The focus is

$(2,-11+ \frac{1}{4} )$

$(2,- \frac{43}{4} )$

$(2,-10.75)$
