To which subset of real numbers does the number 1/4 belong?

2 answers:

8 0

It belongs in rational numbers because if you converted it into a decimal, it would only be .25. If it was a number like pi, then it would be an irrational number because there is almost no end to it.

How old would someone be if they were born on the 30th october 1992 ????

alexdok [17]

Today is March, 19th 2016
so from 1992 have been: 2016 - 1992 = 24 years
but the date is from October 30th, so we are not at 24 years just yet, we are at 23 years and the months and days since last 30th October, that is:
November + December + January + February = 4 months
and some days more, 19 days because today is 19th, so the total is:
23 years, 4 months, 19 days

Can someone help me out please!

Monica [59]

Answer:

Greetings!

The y-intercept denotes the place where the red line crosses the y-coordinate.

Y= the vertical axis

X= the horizontal axis

(If you look closely you will see that the axes are labeled x & y)

So where that ol red line cross the y-axis?

Hint: it's a number between 2 & 4 :)

When you write the answer be sure to put it in fancy coordinates notation, e.g.:

(0,x)

Where x is the value where the red line crosses, and 0 is the x-axis value (since the red line doesn't cross the x-axis where it crosses the y-axis.

Whew, how many times can I write the word "axis" before it starts to look funny?

Anyway, hope that helps dear lad or lassie.

Carry on! You got this!

The graph of the function C(x) = −0.34x2 + 12x + 62 is shown. The function models the production cost, C, in thousands of dollar

Virty [35]

Answer:

0 ≤ x < 1.12 and 34.18 < x ≤ 39.87

Step-by-step explanation:

Let

x ----> is the number of tires produced, in thousands

C(x) ---> the production cost, in thousands of dollars

we have

$C(x)=-0.34x^{2} +12x+62$

This is a vertical parabola open downward (the leading coefficient is negative)

The vertex represent a maximum

The graph in the attached figure

we know that

Looking at the graph

For the interval [0,1.12) -----> $0\leq x$

The value of C(x) ----> $C(x) < 75$

That means ----> The production cost is under $75,000

For the interval (34.18,39.87] -----> $34.18 < x\leq 39.87$

The value of C(x) ----> $C(x) < 75$

That means ----> The production cost is under $75,000

Remember that the variable x (number of tires) cannot be a negative number

therefore

If the company wants to keep its production costs under $75,000 a reasonable domain for the constraint x is

0 ≤ x < 1.12 and 34.18 < x ≤ 39.87

Explain how to find the central angle of a circle?

r-ruslan [8.4K]

Given two points A and B, lines from them to center of the circle form the central angle∠AOB. The central angle is the smaller of the two at the center. It does not mean the reflex angle ∠AOB. As you drag the points above, the angle will change to reflect this as it increases through 180°.
Identify the inscribed angle and central angle subtended by the same arc. Recognize that the central angle is twice the measure of the inscribed angle subtended by the same arc. Identify the tangent(s) to acircle. Identify the point of tangency on a circle
