Finding the Vertex What is the vertex of the quadratic function f(-x) = (x - 3)(x - 2)?

1 answer:

7 0

The vertex is -0.25
Explanation: I have a Casio fx-9750Gll. I pressed menu and clicked on graph. i then typed in the equation and pressed EXE(which is enter). then, i pressed f5(G-Solv) and that gives you two options, Max or Min. you can look at the graph to determine which one it is. but i pressed f3(V-Window) which was the option Min and it gave me (2.5,-0.25) so the answer is -0.25

A geologist examines 6 seawater samples for lead concentration. The mean lead concentration for the sample data is 0.903 cc/cubi

Gnesinka [82]

Answer:

Step-by-step explanation:

We want to determine a 95% confidence interval for the mean lead concentration of sea water samples

Number of samples. n = 6

Mean, u = 0.903 cc/cubic meter

Standard deviation, s = 0.0566

For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean +/- z ×standard deviation/√n

It becomes

0.903 +/- 1.96 × 0.0566/√6

= 0.903 +/- 1.96 × 0.0566/2.44948974278

= 0.903 +/- 0.045

The lower end of the confidence interval is 0.903 - 0.045 =0.858

The upper end of the confidence interval is 0.903 + 0.045 =0.948

Therefore, with 95% confidence interval, the mean lead concentration of the sea water is between 0.858 cc/cubic meter and 0.948 cc/cubic meter

What is the slope of a line that is perpendicular to the line y = 1?

Viktor [21]

Y = 1

Using y = mx + c.

Compare to y = 1, y = 0x + 1 ,

We can see that the slope m = 0 and the vertical intercept, c = 1.

For the line perpendicular to y = 1

Condition for perpendicularity m₁m₂ = -1

m₁ = 0, m₂ = ?

0*m₂ = -1

m₂ = -1/0 = Negative Infinite or Infinite

Slope of line perpendicular to y = 1, is = Infinite.

a collector has 80 jackeys and 125 shirts she wants to maintain ratio in her collection but she needs to sell some of her items

Irina18 [472]

Answer:

Step-by-step explanation:

Well, we need to simplify this. we have a ratio of 80:125.

As these numbers end in either 0 or 5, we know they are divisible by 5.

By dividing these by five, our ratio becomes 16:25.

As we have 16 jackets, we know we must need to sell 25 jackets to maintain the ratio.
