The pattern rule for a sequence is "Start at 10, double the number before this one,
and subtract 1." Write the first five numbers in the sequence.​

Answers

Answer 1
if i’m understanding this correctly, your equation would be 2(n-1) -1. n being the first number you are plugging in, which begins with 10.
10, 17, 31, 59, 115
Answer 2

The first five numbers in the sequence are 10, 19, 37, 73 and 145.

What are sequences?

Sequences are a list of elements (numbers, most of the time) in which the order of elements matters.

Given that, The pattern rule for a sequence is "Start at 10, double the number before this one, and subtract 1."

Forming the equation according to question, we get,

(2n-1)

The first number is 10

2nd = 10x2-1 = 19

3rd = 19x2-1 = 37

4th = 37x2-1 = 73

5th = 73x2-1 = 145

Hence, The first five numbers in the sequence are 10, 19, 37, 73 and 145.

B. The accuracy of shots has improved greatly since 1991.

C. The accuracy of shots has declined greatly since 1991.

D. The accuracy of shots has improved slightly since 1991.

Answers

Answer:

A. is the correct answer and I know that because I just had this question.

Step-by-step explanation:

The best sentence to describe the function is The accuracy of shots has declined slightly since 1991. Hence the correct option is (A).

What is a graph?

The graph is a geometrical representation of any changes whether it is on data or a function that is changing with respect to the other data.

For example, if we take y = sinx then here x is independent and y is dependent.

Here y is changing with respect to the x so if you draw a geometrical representation then it will become a graph where something is changing and something is not.

Given that data

28.0 0.355

29.8 0.354

33.0 0.345

34.3 0.345

34.0 0.341

From this data, it's clear that it is going to decrease year by year.

So the accuracy of shots has declined slightly since 1991 will be correct.

STU is an equilateral triangle. If ST is one less than twice x, SU is 37 less than five times x, and TU is 11 more than x, find x and the measure of each side.

Answers

Answer:

x = 12Side = 23 units

Step-by-step explanation:

STU is an equilateral triangle. And:

ST = 2x - 1SU = 5x - 37TU = x + 11

All sides are equal. Then take one pair and solve for x:

2x - 1 = 5x - 373x = 36x = 12

Substitute x to find the side length:

2x - 1 = 5x - 37 = x + 11 = 23
