Answer: the correct option is option 1

Step-by-step explanation:

The first 3 terms of the sequence are

1, 2, 4, ..

The rate at which each term is increasing is in geometric progression.

The expression for the nth term of geometric sequence is

Tn = ar^n-1

Tn = the nth term of the sequence

a = the first term of the sequence

r = common ratio

From the information given,

The common ratio is expressed as the ratio of a term to its previous consecutive term. It becomes

2/1 = 4/2 = 2. Therefore

r = 2

a = 1

We want to determine the 7th term. It becomes

T7 = 1×2^7-1

T7 = 2^6 = 64

The 7th term is 64

postnew [5]

Answer:

Mabel would have to draw a new angle that measured 97°.

Step-by-step explanation:

Supplementary angles always add up to 180°.

So, she would have to draw an angle that was $180$ ° $- 83$ °

$180-83=97$ .

So Mabel would have to draw a new angle that measured 97°.

Chad will need at least 24 minutes to complete the 5K race. However, he wants to finish in under 30 minutes.

Answer:

The required inequality is: $24 \leq x$

The graph is shown in figure.

Step-by-step explanation:

Consider the provided information.

Chad will need at least 24 minutes to complete the 5K race. However, he wants to finish in under 30 minutes.

Let the time taken to finish the race is represented by x.

Chad need at least 24 minutes and he wants to finish in under 30 minutes.

Thus, the required inequality is:

$24 \leq x$

Now draw the graph of the inequality.

Use a dot or close circle to represents ≤ and use an open circle to represent <.

The value of x is greater than or equal to 24 but less than 30, Thus the required graph is shown in figure.

In which quadrant is the point (0,7) located? Explain your answer.

melisa1 [442]

0, 7 is placed in the top middle quadrant because the x value is 0, therefore it does not move left or right, and y is placed up into the middle. Mark Branliest. :-)
