Which function is equivalent to y = 2(x – 4)^2 + 8?
A. y= 2x² + 24

B y=2x^2 – 16x + 40

C y= 2x^2 – 16x +48

D y=2x² – 8x + 24

Answers

Answer 1

Answer:

B: y = 2x² - 16x + 40

Step-by-step explanation:

You can find this simply by expanding the given function:

y = 2(x - 4)² + 8

y = 2(x² - 8x + 16) + 8

y = 2x² - 16x + 32 + 8

y = 2x² - 16x + 40

Answer:

Coefficient of x = -9.9 ;

Coefficient of x = 75

Coefficient of y = 275

Step-by-step explanation:

Given :

0.8 (2x + x) + 3(7 - 4.1x) = __x + 21

0.8(3x) + 21 - 12.3x = __x + 21

2.4x + 21 - 12.3x = __x + 21

-9.9x + 21 = __x + 21

The sample of the assigned reading likely to be biased and convenience sample.

What is probability?

probability is the ratio of the number of favorable outcomes and the total number of possible outcomes. The chance that a particular event (or set of events) will occur expressed on a linear scale from 0 (impossibility) to 1 (certainty), also expressed as a percentage between 0 and 100%.

Given:

Alana skimmed the first 17 pages from each of the books

assigned in her literature class. Each assigned book has an equal number of pages.

According to given question we have

A biased estimator is one that deviates from the true population value. A biased sample can still be useful if the nature of the bias and how much of a bias exists is known.

An unbiased estimator is when a value from a sample is the same as the actual value of a population parameter.

The sample is not chosen at random, the inherent bias in convenience sampling means that the sample is unlikely to be representative of the population being studied. This undermines your ability to make generalizations from your sample to the population you are studying.

Therefore, the sample of the assigned reading likely to be biased and convenience sample.

Answer:

80%

Step-by-step explanation:

7/8 = 87.5/100

7/10 = 70/100

new equation: 70 is what percent of 87.5

87.5/100=0.875 so 0.875=1% so now we divide 70 by 0.875

70/0.875=80 so 7/10 is 80% of 7/8

Answer:

A & E

Step-by-step explanation:

divide 70 by 5.

you get 14. meaning she charges $14 per hour

14 x 10 gives you 140.

Answer:

y=-1/6x

Step-by-step explanation:

To find the answer you can just look at 2 points on the graph and whichever one comes first is (y1,x1) and the next pair is (y2,x2). So to find it we can use (0,0) automatically because the line is crossing through it. We can also use (600,-100) as the second point becasue it is the next farthest away and when we plug the numbers into the slope equation(y2-y1/x2-x1) we get -100-0/600-0 which when simplified is -100/600 or -1/6 so that would be the m in slope-intercept form (y=mx+b) and when you get everything you can find the equation y=-1/6x

Hope this helped!

A geometric sequence has an initial value of 2 and a common ratio of 3. Which formula would be more practical to use if you were looking find the value of the 19th number in the sequence?

Answers

Answer:

19th term = ar^18

19th term = 774,840,978

Step-by-step explanation:

First term, a = 2

Common ratio, r = 3

nth term of a geometric sequence = ar^(n-1)

19th term = ar^(19-1)

19th term = ar^18

= 2 × 3^18

= 2 × 387,420,489

= 774,840,978

19th term = 774,840,978

Jabari wants to save $66. He earns
$9 every week, walking his
neighbor's dog for 2 hours. He
saves all of his money. How many
weeks will it take him to save $66?

Answers

Answer:

n = 7 1/3 weeks

Step-by-step explanation:

Amount Jabari wants to save = $66

Amount he earns per week = $9

Hours worked per week = 2 hours

How many weeks will it take him to save $66?

Let

n = number of weeks will it take him to save $66

66 = 9n

n = 66/9

n = 7 3/9

n = 7 1/3 weeks

Or

n = 7.33 weeks
