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.

Answer:

m ∠ 2 = 19 * 3 = 57°

Step-by-step explanation:

m ∠ 1 = x

m ∠ 2 = 3x

m ∠ 1 + m ∠ 2 = 76°

3x + x = 76°

4x = 76°

Divide both sides by 4;

x = 19°

m ∠ 1 = 19°

m ∠ 2 = 19 * 3 = 57°

please help me, i don’t get this

Answers

Step-by-step explanation:

you do know that f(x) is the same as y ?

because the y value is the result of a function (in 2-dimensional space).

for such questions we only need to look at the term with the highest exponent of x.

with large values of x this term then "drowns" out all other terms regarding the dimension of the "limit" the range (= functional results) of the function can reach.

so, the term with the highest exponent of x is here

-4x⁶

all the other terms with x⁵, x⁴, x³, ... are much, much smaller in absolute value than |-4x⁶| for really large values of x (x going to infinity, but also to -infinity).

as explained, the term -4x⁶ is therefore driving the limit or end behavior of the function.

so, what happens here, when x goes to +infinity ?

then x⁶ goes to +infinity.

and that means 4x⁶ goes to +infinity.

but that means -4x⁶ goes to -infinity !

and when x goes to -infinity ?

then x⁶ still goes to +infinity (remember, multiplying 2 negative values gives a positive result, so any form of squaring incl. any even exponents will already have positive results).

and that means 4x⁶ goes to +infinity.

but again, -4x⁶ goes then to -infinity.

so the right answer choice is the second one, where y goes to -infinity in both cases.

How much more is the rate of change of function 2 than the rate of change of function 1?

A)1
B)2
C)3
D)4

Answers

Answer:

The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.

Step-by-step explanation:

The rate of change is also known as slope. The slope of a linear function or a line is

It is given that the function 1 is passing through the points (0,3) and (4,3). Slope of function 1 is

Therefore the slope of first function is 0.

The slope intercept form of a line is

Where, m is the slope and b is y-intercept.

The second function is

Therefore the slope of second function is 2 and the y-intercept is 1.

The rate of change of function 1 is 0 and the rate of change of function 2 is 2. The rate of change of function 2 is 2 more than the rate of change of function 1.

Answers

Answer:  1.9 × 10³

Step-by-step explanation:

New born = 2.6 × 10¹⁰ cells.

Adult         = 4.94 × 10¹³ cells.

How many times more = adult cells ÷ newborn cells

                                      = 4.94 × 10¹³ cells ÷ 2.6 × 10¹⁰ cells

                                      =  1.9 × 10³ cells

∴ adults have about 1.9 × 10³ more cells than newborn babies.

6 +4d= 18

4d = 12

d = 3

162= n/2(12+(n -1)3)

324=n(12 + 3n-3)

324=12n + 3n^2 - 3n

3n^2 + 9n-324=0

3n^2+ 36n-27n -324 =0

3n(n+12) -27(n+12)= 0

3n-27 =0; n+ 12=0

Given the function g ( x ) = x 2 + 10 x + 20 g(x)=x 2 +10x+20, determine the average rate of change of the function over the interval − 9 ≤ x ≤ − 3 −9≤x≤−3.

Answers

Step-by-step explanation:

the average rate of change between two input values is the total change of the function values (output values) divided by the change in the input values.

so,

(g(-3) - g(-9)) / (-3 - -9)

g(-3) = (-3)² + 10×-3 + 20 = 9 - 30 + 20 = -1

g(-9) = (-9)² + 10×-9 + 20 = 81 - 90 + 20 = 11

-3 - -9 = -3 + 9 = 6

(-1 - 11) / 6

-12/6 = -2

the average change rate in this interval is -2 (or fully -2/1).

A college student has $240 to use for laundry money. Each time he does laundry, he spends $7.50. Which equation represents the amount of money, M, he has after he has done laundry “x” times?
A) M= 7.50x - 240
B) M= 240 - 7.50x
C) M= 7.50 - 240x
D) M= 240x - 7.50

Answers

Answer:

B

Step-by-step explanation:

x = the number of times he does laundry.

Let's say he does the laundry 5 times then x = 5.

Each time costs $7,50.

If you want to know how much money he has spent after 5 times, you have to calculate 5 times $7,50. 7,5 times 5 = 37.5.

M stands for how much money he still has left from the 240 dollars.

If you apply the formula it would be 'M = 240 - 7.50x (7.50 times 5) = 240 - 37.5 = 202.5'

Therefore, the correct answer is B (M = 240 - 7.50x).
