Answer 1

There is no information displayed.

Here is how to do it.

How to calculate axis of symmetry:

Plug your numbers into the axis of symmetry formula. To calculate the axis of symmetry for a 2nd order polynomial in the form ax 2 + bx +c (a parabola), use the basic formula x = -b / 2a. In the example above, a = 2 b = 3, and c = -1. Insert these values into your formula, and you will get:

How to calculate vertex:

The vertex form of a quadratic is given by

y = a(x – h)2 + k, where (h, k) is the vertex.

The "a" in the vertex form is the same "a" as

in y = ax2 + bx + c (that is, both a's have exactly the same value). The sign on "a" tells you whether the quadratic opens up or opens down. Think of it this way: A positive "a" draws a smiley, and a negative "a" draws a frowny. (Yes, it's a silly picture to have in your head, but it makes is very easy to remember how the leading coefficient works.)

In the vertex form of the quadratic, the fact that (h, k) is the vertex makes sense if you think about it for a minute, and it's because the quantity "x – h" is squared, so its value is always zero or greater; being squared, it can never be negative.

Suppose that "a" is positive, so a(x – h)2 is zero or positive and, whatever x-value you choose, you're always taking k and adding a(x – h)2 to it. That is, the smallest value y can be is just k; otherwise y will equal k plus something positive. When does y equal only k? When x – h, the squared part, is zero; in other words, when x = h. So the lowest value that y can have, y = k, will only happen if x = h. And the lowest point on a positive quadratic is of course the vertex.

If, on the other hand, you suppose that "a" is negative, the exact same reasoning holds, except that you're always taking k and subtracting the squared part from it, so the highest value y can achieve is y = k at x = h. And the highest point on a negative quadratic is of course the vertex.

Given that sec0=-37/12, what is the value of cot0, for pi/2<0

Answers

Answer:

2nd option

Step-by-step explanation:

Using the identities

tan²θ + 1 = sec²θ

cotθ = [tex]\frac{1}{tan0}[/tex]

Given

secθ = - [tex]\frac{37}{12}[/tex] , then

tan²θ + 1 = (- [tex]\frac{37}{12}[/tex] )² = [tex]\frac{1369}{144}[/tex] ( subtract 1 from both sides )

tan²θ = [tex]\frac{1225}{144}[/tex] ( take the square root of both sides )

Since [tex]\frac{\pi }{2}[/tex] < θ < π and tanθ < 0 , then

tanθ = - [tex]\frac{35}{12}[/tex]

Then

cotθ = [tex]\frac{1}{-\frac{35}{12} }[/tex] = - [tex]\frac{12}{35}[/tex]

How many times greater is the value of the 6 in 618,923 than the 6 in 27.652

Answers

600,000 there



- helaaaa

The value of 6 in  618,923 is 1,000,000 or 1 million times greater than that of 6 in 27.652.

What is Place Value?

Place value of a digit in a number is defined as the value of that digit according to the position where it stands.

Place value of a whole number of digits from right to left can be expressed as ones, tens, hundreds, thousand, etc.

Place value of a decimal number after the decimal point from left to right can be expressed as tenths, hundredths, thousandths, etc.

The given numbers are 618,923 and 27.652.

Place value of 6 in 618,923 = 6 × 100,000

That is 6 hundred thousands is the place value.

Place value of 6 in 27.652 = 6 × 1/10 = 6 × 10⁻¹

This is at the tenth place.

6 × 100,000  = 6 × 10⁻¹ × 1,000,000

So 6 × 100,000  is 1,000,000 times greater than 6 × 10⁻¹.

Hence the value of 6 in 618,923 is 1,000,000 times greater than the 6 in 27.652.
