Find y for x=0,1,2, and 3.

y=4-x

Answers

Answer 1
Answer: 4 - (0) = y
4 - 0 = 4      y = 4

4 - (1) = y
4 - 1 = 3     y = 3

4 - (2) = y
4 - 2 = 2     y = 2

4 - (3) = y
4 - 3 = 1     y = 1

Which interval for the graphed function contains the local maximum? A ( -3,-2)
B (-2,0)
C (0,2)
D (2,4)

Answers

Answer:

Option C is correct .i.e., ( 0 , 2 )

Step-by-step explanation:

We are given with a graph.

To find: Interval of local maximum

We can clearly see from graph that there is only one point of maximum.

Point of maximum is ( 1.55 , 10.8 )

Option A:

Interval is ( -3 , -2 ) means x > -3 & x < -2

but this interval does not contain x-coordinate of point of Maximum.

Thus, this option is incorrect

Option B:

Interval is ( -2 , 0 ) means x > -2 & x < 0

but this interval does not contain x-coordinate of point of Maximum.

Thus, this option is incorrect

Option C:

Interval is ( 0 , 2 ) means x > 0 & x < 2

Here, this interval contain x-coordinate of point of Maximum.

Thus, this option is correct

Option D:

Interval is ( 2 , 4 ) means x > 2 & x < 4

but this interval does not contain x-coordinate of point of Maximum.

Thus, this option is incorrect

Therefore, Option C is correct.

if adams plane traveled at a constant speed of 375 miles per hour for four hours, how far did the plane travel?

Answers

distance= speed x time. So 375 (speed) x 4 (time) = 1500 miles.

A type of cell reproduces by splitting itself in half. One cell becomes 2 cells, 2 cells become 4 cells, and 4 cells become 8 cells. What type of sequence does the number of cells represent, and why? It represents an arithmetic sequence because it has a common difference of 2. It represents an arithmetic sequence because it has a common difference of 1/2. It represents a geometric sequence because it has a common ratio of 1/2. It represents a geometric sequence because it has a common ratio of 2.

Answers

It represents a geometric sequence because it has a common ratio of 2.

In fact, a sequence is said to be geometric if any two adjacent elements are in the same ratio. In other words, if you choose any index n \in \mathbb{N} and consider the two consecutive terms a_n and a_(n+1), you have

(a_(n+1))/(a_n) = r

no matter which index you chose. In your case, the next term in the sequence is always the double of the previous one, so the ratio between two consecutive terms is always 2, and the series is geometric with common ratio 2

Answer:

on edge 2021, your answer would be D.) It represents a geometric sequence because it has a common ratio of two.

Which of the following are identities? Check all that apply. A. cot2x + 1 = csc2x B. tan2x = 1 - sec2x C. sin2x = 1 + cos2x D. sin2x + cos2x = 1

Answers


I'll assume those are squares.  We know D is an identity:

\sin^2 x + \cos ^2 x = 1

Dividing through by \sin ^2 x

1 + \cot^2 x = \csc^2 x

That's A.

Dividing the original through by \cos ^2 x

\tan^2 x + 1 = \sec^2 x

Not quite B, wrong sign on tangent.  

C has the wrong sign on cosine squared as well.

Identities: A & D

Answer: A. Cot^2 x+1 =csc^2 x

& D. Sin^2 x+Cos^2 x=1

At the carnival, 9 friends bought 214 tickets.If they wanted to split all the tickets so each friend got the same amount,how many more tickets would they need to buy?

Answers

They would need to by 3 more tickets. 214 divided by 9 = 23 with the remainder of 3. So I divided 217 by 9 = 23. I added 3 to 214 which got a whole answer 23.


I hope I helped.
they need to buy 2 more tickets
214 + 2 = 216

216 tickets /9people  = 24 tickets each person
