Name the points which satisfy the conditions. A negative x-coordinate.

Answers

Answer:

  B, C, G, H, L, M

Step-by-step explanation:

The points with a negative x-coordinate are the points that are to the left of the y-axis. They are ...

  B, C, G, H, L, M

Question 1 (2 points)

(03.04)

For the function f(x) = -(x + 1)2 + 4, identify the vertex, domain, and range. (2 points)

A-The vertex is (-1,4), the domain is all real numbers, and the range is y greater than4.

B-The vertex is (-1, 4), the domain is all real numbers, and the range is y less than4.

C-The vertex is (1,4), the domain is all real numbers, and the range is y greater than 4.

D-The vertex is (1.4), the domain is all real numbers, and the range is y less than4.

Answers

Answer:

The vertex is (-1, 4), the domain is all real numbers, and the range is y less than 4

Step-by-step explanation:

Given

[tex]f(x) = -(x+1)^2 + 4[/tex]

Solving (a): The vertex;

Assume the general form of a function is

[tex]f(x) = a(x-h)^2+k[/tex]

The vertex is determined by [tex](h,k)[/tex]

By comparison, we have:

[tex]-h = 1[/tex]

Solve for h, we have:

[tex]h = -1[/tex]

[tex]k = 4[/tex]

So, the vertex is:

[tex](h,k) = (-1,4)[/tex]

The domain; x is all real numbers

From the function;

[tex]f(x) = -(x+1)^2 + 4[/tex]

This can be rewritten as:

[tex]f(x) = 4 - (x+1)^2[/tex]

This implies that:

Whatever the value of [tex](x + 1)^2[/tex] is, it will be subtracted from 4 to give y or f(x);

Hence:

y is less than 4

The angle of a triangle are in ratio 4:5:6.what is the angle of the triangle?​

Answers

Answer:

48, 60 and 72

Step-by-step explanation:

Given;

    The ratios of the angle in the triangle  = 4:5:6;

Unknown:

The angle of the triangle = ?

Solution:

  We must understand that the sum of angles in a triangle is 180°

 So as ratios;    4:5:6 denotes some certain multiples that sums up to  180°

 Let the multiple number  = x; so

      4x : 5x : 6x

      4x + 5x + 6x = 180

            15x = 180

                = 12

The angles in the triangles are:

        4(12) : 5(12) : 6(12)

        48 : 60 : 72

These angles are 48, 60 and 72

two thirds a number x plus 6 is 8

Answers

2/3x+6 = 8

subtract 6 from both sides

2/3x = 2

divide both sides by 2/3

x = 3

Answer:

x = 3

Step-by-step explanation:

Multiply both sides of the equation by 3

2x + 18 = 24

Move Constant to the right-hand side and change its sign

2x = 24 - 18

Subtract the numbers

2x = 6

Divide both sides of the equation by 2

x = 3

Explain why or why not.
Type your response in the space below.

Answers

Answer/Step-by-step explanation:

Plug in the value of x in each row into the equation, y = 3.2x + 5, to find their corresponding y values respectively.

When x = 1:

y = 3.2(1) + 5

y = 3.2 + 5

y = 8.2

When x = 2:

y = 3.2(2) + 5

y = 6.4 + 5

y = 11.4

When x = 4:

y = 3.2(4) + 5

y = 12.8 + 5

y = 17.5

You have the following table:

x | y

1 | 8.2

2 | 11.4

4 | 17.5

To find out if y is proportional to x, find the ratio of y to x of each pair in the table.

x | y | ratio of y to x (y/x)

1 | 8.2 | 8.2/1 = 8.2

2 | 11.4 | 11.4/2 = 5.7

4 | 17.5 | 17.5/4 = 4.375

As you can see, here is no equal ratio. Each pair has a different ratio. Therefore, the a proportional relationship does not exist between x and y.

a. if the probability of a specific observed event is very small, it is unlikely that the assumption about the probability is correct.
b. the probability of obtaining a favorable outcome increases as the number of trials increases.
c. the sampling distribution of the sample mean will be approximately normally distributed as long as the sample size is sufficiently large.
d. the probability that an event will occur is derived from one's increasing knowledge of relevant circumstances.

Answers

Answer:

c. the sampling distribution of the sample mean will be approximately normally distributed as long as the sample size is sufficiently large

Step-by-step explanation:

The law of large numbers is a statistical law, that states : As sample size grows, the sample mean tends to go closer to whole population mean.

So, the sampling distribution of the sample mean will be approximately normally distributed as long as the sample size is sufficiently large

4. Gabby ate 25 % of a whole pepperoni pizza.
Lebron ate 1/8 of the pizza.
What fraction of the pizza was left for Mohamed to eat?

Answers

Answer:

There is 5/8 left for Mohamed to eat.

Step-by-step explanation:

Let's put everything into fractions of 1/8. knowing that 25% is 1/4 or 2/8, 1/8 + 2/8= 3/8. and to find the answer, you need to subtract 3/8 from 8/8 or 1.

As a result, 5/8.

1/8 = 12.5%

12.5% + 25% = 37.5%

We need to know how much is left.

37.5% is gone, so 100% - 37.5% = 62.5%

62.5% is left for Mohamed to eat.

62.5% = 5/8.

5/8 of a pizza is left for mohamed to eat.

A television costs $400 to purchase. Renting the same telension

cost to purchase it

Answers

Answer:

14 months

Step-by-step explanation:

400 dollars to purchase tv

50 dollars down already in renting television

400-50=350 dollars

350 dollars/ 25 dollars each month for television=14 months

1 year 2 months

Hope this helps!

The number of months will the cost to rent the television equal the cost to purchase it is 1 year 2 months.

Given that, a television costs=$400. Renting the same television requires making a $50 non-refundable deposit plus monthly payments of $25.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Now, 400 dollars to purchase a television.

50 dollars down already in renting television

400-50=350 dollars

Number of months=350/25 =14 months

Therefore, the number of months will the cost to rent the television equal the cost to purchase it is 1 year 2 months.

What is the volume of 22.5 g of metal with a density of 2.81 g/cm

Answers

Answer:V = 72.1 cm³ - 50.0 cm³ = 22.1 cm³

D = mV=99.7g22.1cm³ = 4.51 g/cm³

Step-by-step explanation:

d = mV

m = d×V

V = md

DENSITY

Density is defined as mass per unit volume.

d = mV

Example:

A brick of salt measuring 10.0 cm x 10.0 cm x 2.00 cm has a mass of 433 g. What is its density?

Step 1: Calculate the volume

V = lwh = 10.0 cm × 10.0 cm × 2.00 cm = 200 cm³

Step 2: Calculate the density

d = mV = 433g200cm³ = 2.16 g/cm³

MASS

d = mV

We can rearrange this to get the expression for the mass.

m = d×V

Example:

If 500 mL of a liquid has a density of 1.11 g/mL, what is its mass?

m = d×V = 500 mL × 1.11g1mL = 555 g

VOLUME

d = mV

We can rearrange this to get the expression for the volume.

V = md

Example:

What is the volume of a bar of gold that has a mass of 14.83 kg. The density of gold is 19.32 g/cm³.

Step 1: Convert kilograms to grams.

14.83 kg × 1000g1kg = 14 830 g

Step 2: Calculate the volume.

V = md = 14 830 g × 1cm³19.32g = 767.6 cm³

the triangle and rectangle have an equal perimeter x+5 for the triangle and 2x-3 for the rectangle

Answers

Answer:

Perimeter of triangle = 3(x + 5).

Perimeter of rectangle = 2(2x - 3) + 2x

We know that 3(x + 5) = 2(2x - 3) + 2x

So 3x + 15 = 4x - 6 + 2x, 3x = 21, x = 7.

Hence perimeter = 3(7 + 5) = 36.

(8,2)

Enjoy and Happy Holidays :)

The image of (2,8) after a reflection over the line y = x is (8, 2).

The given coordinate is (2, 8).

What is a reflection over the line y=x?

Reflect over the y = x: When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places.

When we reflect (2, 8) over the line y=x, we get the coordinate as (8, 2). Because the x-coordinate and y-coordinate changed places.

Therefore, the image of (2,8) after a reflection over the line y = x is (8, 2).
