Question 17

Answer: choice C) y = (x-2)^2 - 3

--------------------

Explanation:

We know that a = 1 so it matches with the 'a' value in y = x^2. Otherwise, the shapes wouldn't match up and they wouldn't be congruent.

The vertex we want is (h,k) = (2,-3)

Therefore,

y = a(x-h)^2 + k

y = 1(x-2)^2 + (-3)

y = (x-2)^2 - 3

================================================

Question 18

Answer:  choice B) min point;  -4

--------------------

Explanation:

The equation y = 3(x-1)^2 - 4 is in the form y = a(x-h)^2 + k which is known as vertex form.

a = 3 being positive tells us the graph opens upward and we have a min point. There is no max point as it goes on forever upward.

The min point is k = -4 which is the y coordinate of the vertex.

================================================

Question 19

Answer: Choice B)  y = (1/2)x^2 + 3x - 5

--------------------

Explanation:

The equation opens up, so the value of 'a' must be positive. This narrows our choices to A or B.

We eliminate choice A because that graph is more narrow compared to y = x^2. Choice B is wider and flatter compared to y = x^2 due to 1/2 being smaller than 1.

Answer:

y=-4x+5 or -8/2x+5

Step-by-step explanation:

rise over run, to get the slope. when you do this you get rise is 8 because you count from one point to the other on the y axis and get 13-5=8. Then run is 2 do the same but for the x-axis and get 2-0=2. so you end up with 8/2 or 4 and since the line is going downwards its negative. The y intercept is 5 because that's where it intersects the y-axis. and the 5 is positive because it is a positive y, where the point of intersection is

What is the slope in the Y intercept of the line on the graph below

slope= -4, Y intercept = 1
slope =-4, Y intercept = 4
slope = -1/4, Y intercept = 1
slope = -1/4, Y intercept = 4

Answers

Answer:

just by looking at the graph you can see that the y int is one, so that eliminates two answers already. Then the slope is rise over run. (best thing to remember in math. rise over run) so pick two points. (0, 1) and (4,0) were the first ones i saw. to get from those two points you go from (0,1) over 4 (thats your run) and from there down 1 (thats your rise) to get to (0,4). You would then do rise over run (and because your rise goes down its negative) to get -1/4 as your slope. The answer is slope= -1/4, Y intercept = 1

The mean volume for a bottle of cologne is 4 ounces and the standard deviation is 0.22 ounces. A random sample of 121 bottles is taken. What is the probability of obtaining a sample mean within 0.04 ounces of the population mean?

a. 0.9545
b. 0.0363
c. 0.3085
d. 0.5000

Answers

Answer:

The standard error of the mean is 0.02

Step-by-step explanation:

Here, we want to calculate the standard error of the mean.

Mathematically;

standard error of mean = SD/ √n

where SD is the standard deviation and n is the number of samples

From the question, SD = 0.22 and n = 121

Inserting this into the equation

Standard error of the mean = 0.22/√121

= 0.22/11 = 0.02

The probability of obtaining a sample mean is "0.9545".

According to the question,

Mean,

[tex]\mu = 4[/tex]

Standard deviation,

[tex]\sigma = 0.22[/tex]

Random sample,

[tex]n = 121[/tex]

By Central limit theorem,

→ [tex]\bar {x} \sim (4, \frac{0.22}{\sqrt{121} } )[/tex]

     [tex]= 0.2[/tex]

Now,

→ [tex]P(|\bar{x} - \mu| \ \alpha \ 0.04) = P(-0.04 \ \alpha \ \bar{x} - \mu \ \alpha \ 0.04)[/tex]

                               [tex]= P(\frac{-0.04}{0.02} \ \alpha \ z \ \alpha \ \frac{0.04}{0.02} )[/tex]

                               [tex]= P(-2 \ \alpha \ z \ \alpha \ 2)[/tex]

                               [tex]= 0.9545[/tex]

Thus the above response i.e., "option a" is appropriate.

GIVING BRAINLIEST HELP ASAP!! 3x + 5y = 12 in slope intercept form please show work

Answers

Answer:

y= -3/5x + 12/5

Step-by-step explanation:

Remember, the formula is y= mx + b

#1 So we're gonna put it into that order by subtracting 3x from both sides:

3x + 5y= 12

-3x           -3x

We are left with this:

5y= -3x + 12

#2 Now we will divide 5 to both sides to isolate the variable

5y/5= -3x/5 + 12/5

#3 Now that the variable is isolated we are left with the answer:

y= -3/5x +12/5

(c) What is Mario’s distance given that he ran for 70 minutes? Show your work.

Answers

Answer:

Equation: y = ⅐x

Rate of change: ⅐

Distance = 10 miles

Step-by-step explanation:

Given

The information in the above table

Solving (a): The equation

To get the equation, we need to first calculate the slope (m)

Take any two corresponding values of x and y

(x1,y1) = (7,1)

(x2,y2) = (21,3)

m = (y2 - y1)/(x2 - x1)

m = (3 - 1)/(21 - 7)

m = 2/14

m = ⅐

The equation is calculated using

y - y1 = m(x - x1)

Substitute values for m, x1 and y1

y - 1 = ⅐(x - 7)

y - 1 = ⅐x - 1

Add 1 to both sides

y = ⅐x

Solving (b) Rate of change:

The calculated slope in (a) above represents the rate of change.

So:

Rate of change = Slope = ⅐

Solving (c): Distance when time is 70 minutes

This implies that x = 70

Substitute 70 for x in y = ⅐x

y = ⅐ * 70

y = 10 miles

Prompt: A car is traveling down a highway at the constant speed, described by the equation “d=65t” , where “d” represents the distance, in miles, that the car travels at this speed in “t” hours.

The total cost of required peaches.

Solution:

We know that,

Total cost = Number of units × Cost per unit

Now,

[tex]\text{Total cost of peaches}=\text{Number of peaches}\times \text{Cost per peach}[/tex]

[tex]\text{Total cost of peaches}=4.5\times 1.60[/tex]
