Step-by-step explanation:

y = (x-1)²

vertex (1,0)

y-intercept = (0-1)² = 1

Answer:(-3,-8),(-6,4),(1,-1)

Step-by-step explanation:

Given

Vertices of the triangle are

[tex]P(-3,8), Q(-6,-4),R(1,1)[/tex]

Coordinates (a,b) when reflected about x-axis is given as (a,-b) i.e. Y coordinate changes its sign

[tex]\therefore P\rightarrow P'(-3,-8)\\\Rightarrow Q\rightarrow Q'(-6,4)\\\Rightarrow R\rightarrow R'(1,-1)[/tex]

Answer:

y = 1/2x + 2

Step-by-step explanation:

slope:

6 - 3 / 8 - 2 = 3 / 6 = 1/2

start by putting it in point slope form and then simplify it to slope intercept form:

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

y - 3 = 1/2x - 1

y = 1/2x + 2

Answer:

4

Step-by-step explanation:

so when it says f(x)=-x+1

the x values are constant so what value is in f(x) the value of x goes right into -x+1

f(-3)=-x+1

f(-3)=-(-3)+1

f(-3)=4

Answer:

it's D 200 for sure my answer I correct

Answer:

Step-by-step explanation:

First off use algebra tiles, Didax has a good one. So basically x*x is x^2 right? and 4*3 is 12 right? also 4x+3x=7x. So the answer is x^2+7x+12! :)

Find the stationary points.

f(x) = 3x ⁴ - 4x ³ - 12x ² + 1

f '(x) = 12x ³ - 12 x ² - 24x

Solve f '(x) = 0.

12x ³ - 12 x ² - 24x = 12x (x ² + x - 2) = 12x (x - 1) (x + 2) = 0

→   x = 0, x = 1, x = -2

Check the value of f at the stationary points.

f (0) = 1

f (1) = -12

f (-2) = 33

Check the value of f at the boundary of the domain.

f (3) = 28

(We've already checked f (-2).)

Then over [-2, 3], we have max(f ) = 33 and min(f ) = -12.

Hi there!

[tex]\large\boxed{x = -9, 0}[/tex]

Find the zeros using factoring:

f(x) = x³ + 9x²

Factor out the common term, or x²:

f(x) = x²(x + 9)

Set each factor equal to 0:

x² = 0

x = 0

x + 9 = 0

x = -9

The zeroes are -9, 0.

Answer:

The standard error of the difference in the mean number of fish caught before and after the fire is 0.2153.

Step-by-step explanation:

Subtraction of normal variables:

When we subtract two normal variables, the standard deviation is the square root of the sum of variances of each variable.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Sample of 195 fishing reports before the fire, the mean catch was 6.3 fish with a standard deviation of 1.6.

The standard error for this sample is:

[tex]s_b = \frac{1.6}{\sqrt{195}} = 0.1246[/tex]

Sample of 143 reports three years after the fire, the mean catch was 7.1 fish with a standard deviation of 2.1.

The standard deviation for this sample is:

[tex]s_a = \frac{2.1}{\sqrt{143}} = 0.1756[/tex]

What represents the standard error of the difference in the mean number of fish caught before and after the fire?

[tex]s = \sqrt{s_a^2 + s_b^2} = \sqrt{0.1756^2 + 0.1246^2} = 0.2153[/tex]

The standard error of the difference in the mean number of fish caught before and after the fire is 0.2153.

Answer:

sqrt [ (1.6^2)/195 + (2.1^2)/143 ]

Answer:

it is data

just look at it and describe its properties

Answer:

an outlier is a number that is at least 2 standard deviations away from the mean for example in the set 1,1,1,1,1,1,1,1,1,7,7,7 would be the outlier

Answer: is b- right

Step-by-step explanation:

We want to see how the graph of the parent function compares to the graph of the transformed function.

The transformed function is a reflection across the x-axis, followed by a translation of 6 units to the right, followed by a vertical dilation of scale factor 3 of the parent function.

The parent function is y = √x

The transformed function is y = -3*√(x - 6)

So there are 3 transformations applied to the parent function, let's describe these generally.

Reflection across the x-axis:

For a function f(x), a reflection across the x-axis just changes the sign:

g(x) = -f(x).

Horizontal shift:

For a function f(x), a horizontal shift of N units is written as:

g(x) = f(x + N)

Vertical dilation:

For a function f(x), a vertical dilation of scale factor K is written as:

g(x) = K*f(x)

Then from the parent function to the transformed function, we have:

A reflection across the x-axis, followed by a translation of 6 units to the right, followed by a vertical dilation of scale factor 3.

Answer:

Perimeter of rectangle = 30 - 12y

Step-by-step explanation:

Given:

Width of rectangle = 5 - 2y

Length of rectangle = 2(width) = 2[5 - 2y] = 10 - 4y

Find:

Perimeter of rectangle

Computation:

Perimeter of rectangle = 2[l + b]

Perimeter of rectangle = 2 [10 - 4y + 5 - 2y]

Perimeter of rectangle = 2[15 - 6y]

Perimeter of rectangle = 30 - 12y

Answer:

Using weighted average, the cost of goods sold for the sale of 23 units on July 31 is $2,504.70, and the inventory balance at July 31 is $ 1,306.90.

Step-by-step explanation:

Since Intercontinental, Inc., uses a perpetual inventory system, and on July 1, purchased 10 units for $ 910 or $ 91 per unit; on July 3, purchased 15 units for $ 1,590 or $ 106 per unit; on July 14, it sold 20 units; on July 17, purchased 20 units for $ 2,300 or $ 115 per unit; on July 28, purchased 10 units for $ 1,190 or $ 119 per unit; and on July 31, sold 23 units, to determine the average costs and the inventory balance as of July 31, the following calculations must be performed:

(910 +1590 + 2300 + 1190) / (10 + 15 + 20 + 10) = X

5990/55 = X

108.90 = X

108.90 x 23 = 2504.7

(55 x 108.9) - (43 x 108.9) = X

5990 - 4683.10 = X

1306.90 = X

Using weighted average, the cost of goods sold for the sale of 23 units on July 31 is $ 2504.70, and the inventory balance at July 31 is $ 1,306.90.

Answer:

Electromagnetic Radiation

Step-by-step explanation:

The building will be making 90° with the ground/horizontal.

Then we can apply Pythagoras theorem.

(Base)² + (Height)² = (Hypotenuse)²

=> x² + (12 foot)² = (37 foot)²

=> x² = (37 foot)² - (12 foot)²

We can expand LHS using a² - b² = (a + b)(a - b)

=> x² = (37 + 12 foot)(37 - 12 foot)

=> x² = 49 * 25 foot²

=> x² = (7 * 5)² foot²

=> x = 7 * 5 foot

=> x = 35 foot.

Answer:

The proportion of disks which are defective is 0.16.

Step-by-step explanation:

The proportion of defective disks is the number of defective disks in the sample divided by the size of the sample.

In this question:

2346 disks.

1971 not defective, so 2346 - 1971 = 375 defective.

[tex]p = \frac{375}{2346} = 0.16[/tex]

The proportion of disks which are defective is 0.16.
