WITCHER [35]3 years ago
6 0

For this case we have the following data:

Drained 3.5 Liters in 4 days. If we want to know the volume of water per day, we make a rule of three:

3.5 Liters -----> 4days

x Liters --------> 1 day

Where x represents the amount of water drained each day.

So, we have to:

x =\frac{(1 * 3.5)}{4}

x = 0.875 Liters  per day

So, the average change in water volume each day is:x = 0.875 Liters  per day

Answer:

x = 0.875Liters per day

The vertex of this parabola at (-5,-2). When the c - value is -4 the y-value is 2 what is the coefficient of the squared express
Andre45 [30]

Answer:

4

Step-by-step explanation:

The vertex formula of a quadratic equation is:

●y= a(x-h)^2 +k

(h,k) are the coordinates of the vertex

Here: h = -5 and k= -2

y is 2 and x is -4

● 2 = a (-4-(-5))^2 + (-2)

● 2 = a (-4+5)^2 -2

● 2 = a *1^2 -2

● 2 = a -2

● 4 = a

A rectangle is 32m by 8m is similar to a rectangle 4m by x m. Find the 2 possible values of x .
Stella [2.4K]
<h3>Answers:</h3><h3>x = 1 or x = 16</h3>

======================================

Work Shown:

Draw out a rectangle that is 32 units wide horizontally and 8 units tall vertically.

Then draw out another rectangle that is 4 meters wide horizontally and x meters tall vertically.

The horizontal and vertical sides pair up to form these fractions: 32/4 and 8/x

Set the fractions equal to one another. Solve for x

32/4 = 8/x

32x = 8*4 ... cross multiply

32x = 32  

x = 32/32 ... divide both sides by 32

x = 1

-----------------------

Somewhere else on your paper, draw the same 32 by 8 rectangle to make 32 the horizontal component

Next to this rectangle, draw a rectangle that has x as the horizontal part and 4 as the vertical. Note the swap here.

We now have this equation to solve for

32/x = 8/4

once again, note the swap

Let's solve for x

32/x = 8/4

32*4 = 8*x

128 = 8x

8x = 128

x = 128/8

x = 16

rjkz [21]
The number of members in a baseball club is shown with the function:
f ( x ) = 25 * 1.45^x
When: x = 0: f ( 0 ) = 25
When x = 1  f ( x ) = 25 * 1.45 ≈ 36
When x = 3,  f ( x ) = 25 * 1.45³ ≈ 76
