write a function g whose graph represents the indicated transformation of the graph of f. f(x)=|x+1|-3; horizontal stretch by a factor of 9.​

Answers

Answer:

f(x) = |[tex]\frac{1}{9}[/tex](x+1)|-3

Step-by-step explanation:

The value representing the horizontal scaling must be placed inside the absolute value, and we need to put () around x - 1 to change the horizontal shift as well. And remember that we must use the reciprocal in the function, so instead of writing y = |9(x+1)|-3, we need to write y = |[tex]\frac{1}{9}[/tex](x+1)|-3.

A binomial experiment has 4 trials in which p=0. 35. What is the probability of 1 success?.

Answers

Answer: 5798

Step-by-step explanation:

Probability of [tex]1[/tex] success as per given condition is equals to [tex]0.384475[/tex] ≈ [tex]0.4[/tex].

What is probability?

" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes.Probability is always less than or equals to one."

Formula used

For binomial experiment

Probability =  [tex]^n C_r p^{r} q^{n-r}[/tex]

[tex]p =[/tex]success rate

[tex]q=[/tex] failure rate

[tex]p+q=1[/tex]

[tex]n=[/tex]Number of trials

[tex]r=[/tex] number of success

According to the question,

Total number of trials [tex]'n' =4[/tex]

Number of success [tex]'r' =1[/tex]

[tex]p = 0.35\\\\q = 1-0.35\\ \\\implies q = 0.65[/tex]

Substitute the value to get the required probability,

Probability [tex]= ^4C_1 (0.35)^{1}(0.65)^{4-1}[/tex]

                   [tex]=\frac{4!}{(4-1)!1!} \times\frac{35}{100}\times(\frac{65}{100})^{3} \\\\= 4 \times \frac{35}{100}\times \frac{274625}{1000000} \\\\= 0.384475[/tex]

                   ≈ [tex]0.4[/tex]

Hence, probability of [tex]1[/tex] success as per given condition is equals to [tex]0.384475[/tex] ≈ [tex]0.4[/tex].

How do I do this? I’m confused

Answers

I’m not exactly sure what part you’re confused about so I’ll explain this problem for you. The first step would be knowing what slope intercept form is; y=mx+b. Knowing this, our first step (the easiest one) would be to find “b” also known as the y intercept, all you need to do is find where the slope crosses on the y axis. In your case, this is at the point (0,-6) so b (the y intercept) would be -6. Now for the next step you need to find the next point (from the y intercept -6) where the slope intercepts the y axis (this is always going to be left of the y intercept). So if you look closely, the next point the slope intercepts is (5,-8) which will now become our “m” in the equation. Finally all we need to do is plug them in slope form. The final answer will be y=-5/8x-6


If you have any further questions; or if I didn’t clear your confusion please don’t hesitate to reply to this answer. I’ll be more than happy to further assist you!

Solve for x 2(x - 2)² = (2x - 1)(x - 3)
answer please ​

Answers

Answer:

X = 5

Step-by-step explanation:

Answer: x = 5

Step-by-step explanation:

Solve for x given the equation 2(x - 2)² = (2x - 1)(x - 3).

Simplify the equation.

2(x - 2)(x - 2) = (2x - 1)(x - 3)

2(x² - 4x + 4) = (2x² - 7x + 3)

2x² - 8x + 8 = 2x² - 7x + 3

Solve for x.

2x² - 8x + 8 = 2x² - 7x + 3

              -8                  - 8

2x² - 8x = 2x² - 7x - 5

       +8x         + 8x

2x² = 2x² + x - 5

 -x              - x

2x² - x = 2x² - 5

-2x²      - 2x²

- x = - 5

- 5 ÷ - 1 = 5

x is equal to 5.

Gemma is solving a division problem. After writing the problem down, she moves the decimal point directly up to the quotient. Which of these is true of Gemma’s divisor?
A
It is 0.

B
It is negative.

C
It is a decimal.

D
It is a whole number.

Answers

C? im pretty sure its c

hope this helps!

C. It is a decimal, it is true of Gemma’s divisor.

The correct answer is: C. It is a decimal.

When Gemma moves the decimal point directly up to the quotient, she is essentially performing long division by powers of 10.

This is because when you divide a number by a power of 10, you are essentially shifting its decimal point to the left by the number of positions determined by the power of 10.

For example, if she is dividing by 100 [tex](10^2)[/tex], she is moving the decimal point two places to the left.

If she is dividing by 1000 [tex](10^3)[/tex], she is moving the decimal point three places to the left, and so on.

Moving the decimal point up to the quotient means that the divisor is a decimal number, and its value determines how many decimal places Gemma needs to move the decimal point in the dividend to get the quotient.

So, the correct answer is C. It is a decimal.

A mass oscillating up and down on the bottom of a spring (assuming perfect elasticity and no friction or air resistance) can be modeled as harmonic motion. If the weight is displaced a maximum of 6 cm, find the modeling equation if it takes 4 seconds to complete one cycle. Be to show, illustrate and explain your work.

Answers

The motion of the mass as it moves on the bottom of the spring is a

repetitive motion.

[tex]\mathrm{The \ motion \ of \ the \ mass \ attached \ to \ the \ spring \ is \ }\displaystyle d = 6 \cdot sin\left(\frac{\pi}{2} \cdot t \right)[/tex]

Reasons:

The general form of the equation of the simple harmonic motion of the

mass is d = a·sin(ω·t)

Where;

d = The distance of the mass from the rest position

a = The maximum displacement of the mass from the equilibrium position = 6 cm

ω = The frequency of rotation

t = The time of motion

ω = The frequency of rotation

[tex]\displaystyle \omega = \mathbf{\frac{2 \cdot \pi}{T}}[/tex]

Where;

T = The time to complete one cycle (the period of oscillation) = 4 seconds

[tex]\displaystyle \omega = \frac{2 \cdot \pi}{4} = \frac{\pi}{2}[/tex]

Combining the above values gives the modelling equation as follows;

The ratio of the sides of two similar hexagons is 3:4. If the area of the smaller hexagon is 36 cm2, what is the area of the larger hexagon? (A
hexagon has 6 sides)

Answers

Answer:

64 cm²

Step-by-step explanation:

Given 2 similar figures with ratio of sides = a : b , then

ratio of areas = a² : b²

Here ratio of sides = 3 : 4

ratio of areas = 3² : 4² = 9 : 16

let x be the area of the larger hexagon then by proportion

[tex]\frac{9}{16}[/tex] = [tex]\frac{36}{x}[/tex] ( cross- multiply )

9x = 16 × 36 = 576 ( divide both sides by 9 )

x = 64

Area of larger hexagon = 64 cm²
