If f(x) = k(x - 2)^2, where k is positive, what is the effect on the graph of f(x) as k increases

Answers

The answer is B. Lana Rhoades

Answer:

The value of k determines where the parabola is on the y-axis. In other words, its "height". If k we're to be positive, the parabola would move to the positive side of y-axis, not negative.

line parallel to y=8-1/8x

Answers

Answer:

Y = (-1/8) X + C is the equation of a line parallel to y=8-1/8x

Step-by-step explanation:

Complete question.

Find the line parallel to y=8-1/8x

Solution

For two lines to be parallel to each other it is essential that their slopes must be same

For any line of the form

Y = mX +b

m is the slope

Here the equation of given line is  y=8-1/8x

on rearranging, we get

Y = (-1/8) X + 8

here m = (-1/8)

Hence, line parallel to y=8-1/8x is any line with slope equal to (-1/8)

Or we can say that equation of parallel line would be

Y = (-1/8) X + C

A 20-minute consumer survey that included a $5 Starbucks gift card was emailed to 500 adults aged 25-34. The survey resulted in 65 responses. The same 20-minute consumer survey was emailed to 500 adults aged 25-34 without the Starbucks gift card. The survey resulted in 45 responses. We would like to know if the inclusion of a Starbucks gift card led to any change in survey response rate. Which of the following hypotheses should be used?
A. Null Hypothesis: mul (average number of responses with Starbucks gift card)<= muo(average number of responses without Starbucks gift card) Alternative Hypothesis: mu1 ( average number of responses with Starbucks gift card)> muo(average number of responses without Starbucks gift card)
B. Null Hypothesis: mu1 (average number of responses with Starbucks gift card)= mud (average number of responses without Starbucks gift card) Alternative Hypothesis: mu1 ( average number of responses with Starbucks gift card) \= mul ( average number of responses without Starbucks gift card) * \= means "not equal to"
C. Null Hypothesis: pi1 (rate with Starbucks gift card)= pi2 (rate without Starbucks gift card) Alternative Hypothesis: pi1 (rate with Starbucks gift card) (= pi2 (rate without Starbucks gift card) * \= means "not equal to"
D. Null Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card)<=0 Alternative Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card) > 0

Answers

Answer:

D. Null Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card)<=0 Alternative Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card) > 0

Step-by-step explanation:

The test described above test the difference in proportion :

With Starbucks gift card :

x1 = 65 n1 = 500

Phat 1 = x1 / n1

Phat 1 = 65 /500 = 0.13

Phat1

Without Starbucks gift card :

x2 = 45 n2 = 500

Phat1 = x2 / n2

Phat 2 = 45 / 500 = 0.09

To test the difference in proportion :

Phat 1 > Phat 2 (alternative)

Null takes the stance that there is no difference in proportion

Phat1 - phat2 <=0

Alternative claims that there is difference on proportion such that phat 1 is greater than phat 2

Phat 1 - phat > 0

Solve for x. 20x + 5 =5x+65

Answers

Answer:

x = 4

Step-by-step explanation:

subtract 5 from all sides

20x+5-5=5x+65-5

simplify

20x=5x+60

subtract 5x from both sides

20x-5x=5x+60-5x

simplify again

15x=60

Divide both sides by 15

15x/5 = 60/15

lastly simplify to get your answer of

x = 4

Given right triangle ABC with altitude BD drawn to hypotenuse AC. If AB = 24

A
12
D
24

Answers

Answer: x=48

Step-by-step explanation:

The length AC of the right-angle triangle will be 48 units.

What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

According to the hypotenuse-leg (HL) principle, a right triangle is harmonious if each of its third side and legs are congruent with its equivalent hypotenuse and legs in another right triangle. The HL theorem proves that these triangles are identical.

AC / AB = AB / AD

AC / 24 = 24 / 12

AC = 48 units

The length AC of the right-angle triangle will be 48 units.
