Estimate the product 2.1 x 0.9

Answers

Answer 1

Answer:

2.0 estimated product

1.89 Actual product

Step-by-step explanation:

2.0*1.0=2.0

2.1*1.0=1.89

Answer 2

The product of 2.1 x 0.9 = 1.89

What is Product?

A product is something that has been multiplied one or more times. For instance, the mathematical formula "times equals" would be written with the terms "times," "multiplicand," and "product," respectively.

Given:

2.1 x 0.9

Now, Multiplying

                          2  .  1

                       x 0  .  9

                      _________

The graph which have slope 4/5 is Graph II.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have the graph.

As, we know slope= rise / run

In graph 1 the slope is

Slope= rise/ run

slope= 4/4

slope= 1

In graph 2 the slope is

Slope= rise/ run

Slope = 4/5

In graph 1 the slope is

Slope= rise/ run

Slope= 2/5

Thus, Graph II have slope 4/5.

Answers

Answer:

Coordinates A and B: (1, 0) and (3, 0)

Coordinates of P: (0, 3)

Coordinates of Q: (2, -1)

Step-by-step explanation:

You're pretty much given the x-intercepts from the original equation.

y = (x - 1)(x - 3). So to get the x-intercepts (points A and B), y has to equal 0. So,

0 = (x - 1)(x - 3).

and y = 0 when x equals 1 and 3. Because anything multiplied by 0 equals 0. So substituting 1 for the value of x, for example, we get:

0 = (1 - 1)(1 - 3)

0 = 0 * (-2)

So there are your x-intercepts, points A and B.

Now,

Expand the brackets of the equation.

y = (x - 1)(x - 3) becomes

y = x^2  -  4x  + 3

You get the y-intercept (point P) by substituting 0 for the value of x. Doing so gives:

y = 0^2 - 4*0 + 3

y = 0 - 0 + 3

y = 3

So, we have our y-intercept (0, 3).

Point Q, the x-coordinate of the vertex is calculated with the equation -b/2a

Taking our expanded equation: x^2 - 4x + 3

which is of the form ax^2 + bx + c

So we find the values of a, b and c and input the values into the equation

a = 1

b = -4

c = 3

So, inputting these into the vertex equation, gives:

-(-4) / 2 * 1

4 / 2

2

So we have the x-coordinate of the vertex. Now that we know that, we can just substitute it into the expanded equation to give the y-coordinate:

y = 2^2 - 4*2 + 3

y = 4 - 8 + 3

y = -1

So there's our y-coordinate, and now we have both the x and y coordinate for the vertex, point Q. (2, -1).

An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. The drain pipe can be used to empty the pool in 34 hours. If the pool is [tex]\frac{2}{3}[/tex] filled and then the inlet pipe and drain pipe are opened, how many more hours would it take to fill the pool? Round your answer to two decimal places, if needed.

Answers

Answer:

374 hours

Step-by-step explanation:

Filling rate is 1/33Draining rate is 1/34

The difference is the filling rate with both lines open:

1/33 - 1/34 = 1/1122

The pool is 2/3 full and needs filling the remainder, 1/3.

Time required to fill:

1/3 : 1/1122 = 1122/3 = 374 hours
