In this question, we're trying to find the depth of the fish after 12 seconds

We know that the fish descends at a rate of 18 in. per second.

We need to represent this as an equation

Our equation would be:

y = -18x

x = seconds of descending

y = depth

We don't know where the fish started, so we can assume that it started at a depth of 0

Plug in 12 to the equation and solve:

y = -18(12)

y = -216

The fish would be at a depth of -216 inches.

Answer:

-216 inches

Answer:

216 inches/ 18 feet

Step-by-step explanation:

Multiply the descension by the number of seconds.

18*12 = 216 inches, or 18 feet.

The volume of a cube is 1 cubic meter. What is the length of of each side of the cube
julsineya [31]
1 Metre is the length of each side of the cube.

To example, here is the Volume Of Cube Equation:

V = a^3

We are given the value for V, so just take the cube root of 1, which equates to 1.

write the slope- intercept form of the equation of the line parallel to - x+5y=25, passing through the point (-5,-5). simplify
Olenka [21]
To find the equation of a line that is parallel to your original equation and goes through a certain point on a graph, here's what you need to know:
First you need to find the slope of your original equation.
To do that, you need to convert it to slope intercept form (y = mx+b).
Add the x over, and then divide everything by 5 to get the y by itself.
Here's what that would look like (without the small steps that I mentioned):
-x + 5y = 25
5y = x + 25
y = 1/5x + 5

That's the original equation rewritten in slope intercept form.
The m represents the slope, so this equation's slope is 1/5.

Because you are given a point, and now you have a slope, the best and easiest route is using point slope form.
I've seen different versions of the equation base but I prefer y - y(sub1) = m(x - x(sub1))
But since I can't use subscripts in this, I'll use the one with h and k. The h is the x value of the point, and the k is the y value.
(h,k)
Then just substitute the values in and solve for y.
y - k = m(x - h)
y + 5 = 1/5(x + 5)
y + 5 = 1/5x + 1
y = 1/5x - 4

Your final answer is
y = 1/5x - 4
You can double check by using a graph. If the slopes are the same, the lines should be parallel.

I hope that helps. If anything didn't make sense, feel free to ask me.

A number of friends decided to go on a picnic and planned to spend rs. 96 on eatables. four of them, however, did not turn up. a
mr Goodwill [35]

The number of those who attended the picnic was 8.

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax^{2} + bx + c = 0 where a, b, c, ∈ R and a ≠ 0.

Such questions are best examples of quadratic equations where  the unknown is simply assumed to be a variable which when substituted according to the conditions yield a quadratic equation which can easily be solved.

Let x represent the whole population.

Total Spending = Rs. 96

Thus, each individual's contribution is equal to 96/x.

Four people did not show up causing

others to contribute Rs. 4 extra.

So the given condition can be written as

96/(x-4) – 96/x = 4

=>96x – 96(x-4) = 4x(x-4)

=> 96x -96x + 384 = 4x2 – 16x

=> 4x2 – 16x – 384 = 0

=> x2 – 4x – 96 = 0

=> (x – 12)(x + 8) = 0

=> x = 12 or x = -8 (neglect)

So x = 12

x-4 = 8  ( because  four of them did not turn up)

∴ The number of those who attended the picnic was 8.
