The height of the rocket after 5 seconds would be 0 feet.

A quadratic equation is in the form:

y = ax² + bx + c

Let y represent the height after x seconds.

At point (0, 0):

0 = a(0)² + b(0) + c

c = 0

At (0.5, 20.5):

20.5 = a(0.5)² + b(0.5) +0

0.25a + 0.5b = 20.5

At point (2, 36.25):

30.41 = a(2)² + b(2) + 0

4a + 2b = 30.41

Hence:

a = -17.2, b = 49.6

Hence:

y = -17.2x² + 49.6x

At 5 seconds:

y = -17.2(5)² + 49.6(5) = -197

The height of the rocket after 5 seconds would be 0 feet.

Answer:

3.66666. . . = 11/3 = 3  2/3

Step-by-step explanation:

Use distributive property.

3 ⋅ x = 3x

3 ⋅ (-1) = -3

3x - 3 + 4 = 12

Add -3 to 4

1

3x + 1 = 12

Subtract 1 from both sides.

3x = 11

Divide both sides by 3

3.666666. . .

This can also be written as 11/3

11/3 can be simplified to 3  2/3

Answer:

Rate of change = -12

Step-by-step explanation:

y − 3 = −12(x + 4)

Expanding, we have;

y - 3 = -12x - 48

y = -12x - 48 + 3

y = -12x - 45

Now, formula for rate of change is;

Rate of change = (y(x + h) - y)/h

y(x + h) is; y = -12(x + h) - 45

This gives;

Rate of change = (-12(x + h) - 45 + 12x + 45)/h

Rate of change = (-12x - 12h - 45 + 12x + 45)/h

Rate of change = -12h/h

Rate of change = -12

Sorry, I couldn't figure out the last one, it just takes a lot of trial and error and luck :(

You know that S times A is the digit N. Then, A squared plus whatever the first digit of the2 digit number XN is MA.

A cannot be five because if you were to do 5 times 5 it would be 25. A squared is 25 and the last digit is already A so added on to anything else the equation would be false. So the only considerable value for S would be one, but then A times S would be 5, but N is not A. I hope you get what I mean.

A cannot be 6 for the same reason (just change the 5 to six on my last pragraph).

If A were 7 then you'd have to find something to add to 49 to make it end in 7, which means adding 6. 7 times 9 is 63, so S could be 9. 79 times 7 is 573. That is the answer. A = 7, S = 9, M = 5, N = 3.

As for NINE - FOUR = FIVE, E - R is E so R must be 0.The only one digit number a number can be subtracted by to get itself is 0.

Now, N - U = V, or 1N - U = V

Let's say N is 3 and U is 6. V would be 7.

We've just took one from I. I - 1 - O = I. 1+O must be 10 or 0, but O must be positive, so O = 9. Let's say I is 5.

We just borrowed one form N. N-1 - F = F. N - 1 = 2 times F.

But we know that N is 3. 2 = 2 times F. F is 1.

Let's just make E = 8

My final answer is 3538 - 1960 = 1578

There are MANY other answers though.

N = 3, I = 5, E = 8, O = 9, U = 6, R = 0, V = 7.

Answer:

C

Step-by-step explanation:

The correct option is C because lines can extend its length in both side infinitely. It contains arrowheads indicating it can extend.

Pls rate.........

A line is an undefined term because it describes something that does not have width or depth. thus, option C is correct answer.

If the ray lies onto the considered line segment(overlapping), then it can be said belonging to the considered line segment.

(line segment has 2 fixed ends, whereas a ray has one end only, other end is not fixed)

A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).

A lines can extend its length in both side infinitely. It contains arrowheads indicating it can extend.

A line is an undefined term because it describes something that does not have width or depth. thus, option C is correct answer.

1,3 is right correct right answer

The coordinate point for A is (1,3) Therefore, option B is the correct answer.

WE know that rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides.

Since a rhombus has all four sides equal just like a square.

Given that, Point C (2, 1), Point B (3,4) and Point D (4,2)

The coordinate point for A that would make ABDC a rhombus.

So, the coordinate point for A is (1,3).

Therefore, option B is the correct answer.

Answer:

The answer is congruent

Answer: a)  Unimodal and symmetric

b) 0.26

c) 0.038

Step-by-step explanation:

Given: Sample size of investors (n)= 131

True proportion of smartphone users(p)  =26%

a) Since sampling distribution for the sample proportion is approximately normal when n is larger.

Normal distribution is Unimodal and symmetric.

So correct option : Unimodal and symmetric

b)  mean of this sampling​ distribution = p = 0.26

c)  standard deviation of the sampling​distribution = [tex]\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.26\times (1-0.26)}{131}}=\sqrt{0.00146870229008}[/tex]
