help please, which pic is it a, b, c or d?

Answer:

x≤−32

Step-by-step explanation:

The coordinates of N' will be (4.5, 5.25)

The picture is given by the product of the corresponding point on the preimage and the scale factor, with the center of dilatation at the origin.

The origin is the center of dilatation of a quadrilateral MNOP.

The picture that results from the dilatation of MNOP = M'N'O'P'

The dilation scale factor is 1.5.

N's coordinates in MNOP = N (3, 3.5)

The coordinates of a point (x', y') on the picture after dilatation with the center at the origin, of the preimage (x, y) by a scale factor are given below;

   (x', y') = Scale factor × (x, y)

Which gives;

The coordinates of N' = 1.5 × N(3, 3.5) = N'(1.5 × 3, 1.5 × 3.5) = N'(4.5, 5.25)

The coordinates of N' = (4.5, 5.25)

Having a rectangular pasture for the animals to graze in is something a farmer wants in order to start growing cows, horses, goats, and sheep. She has decided to purchase 7500 ft of fencing. 1875 square feet is the maximum possible area that each of the four pens will enclose.

The maximum possible area of each pen is 1875 square feet. To calculate this, first calculate the total area of the large rectangle that the farmer is enclosing. To do this, multiply the total length of the fencing (7500 feet) by the width of the fence (1 foot). This gives us 7500 square feet as the area of the large rectangle.

Next, divide the area of the large rectangle by 4 to get the area of each pen. This gives us 1875 square feet as the maximum area of each pen.

Total Area of Large Rectangle = 7500 ft x 1 ft = 7500 sq ft

Area of Each Pen = 7500 sq ft / 4 = 1875 sq ft

What is radioactive decay?

The process of radioactive decay is how an unstable atomic nucleus loses energy through radiation. A substance that has unstable nuclei is regarded as radioactive.

Here,

The half-life of the reaction is defined as the time required by a substance to reach half its initial concentration. It is represented by t(1/2)

 All radioactive decay processes follow the first-order reaction.

The equation for the half-life for first-order reaction follows:

t(1/2) = 0.693/k....(1)

where,

k = rate constant of a first-order reaction

Given value:

t(1/2) = 5715 years

Put the value of t in equation (1), and we get

k = 0.693/5715

k = 1.21×10⁻⁴yr

The integrated rate law expression for first-order reaction follows:

t = 2.303/k×㏒(a/(a-x))

where,

t = time period

a = initial concentration of the reactant = 58.2 counts per minute

(a-x) = Concentration of reactant left after time t = 38.0 counts per minute

k = rate constant of a first-order reaction

Put the values in the equation and we get

t = 2.303/1.21×10⁻⁴㏒58.2/38

t = 3523.77 years.

Hence, the age of the artifact is 3523.77 years.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 - 9 is an equation.

We have,

Number of multiple choice questions = M

Number of open response questions = N

We can make two equations.

M + N = 36 _______(1)

3M + 5N = 120 ______(2)

From (1) we get,

M = 36 - N ______(3)

Putting (3) in (2) we get,

3(36 - N) + 5N = 120

108 - 3N + 5N = 120

2N = 120 - 108

2N = 12

N = 6

Now,

Putting N = 6 in (3) we get,

M = 36 - 6

M = 30

Answer: 31.99$ or 32$

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 39.99 × 20/100

Discount = 39.99 x 0.2

You save = $8.00

Final Price = Original Price - Discount

Final Price = 39.99 - 7.998

Final Price = $31.99

Answer:

x/39.99 is the same as 20%/100% so you would cross multiply 39.99 x 20 then divide by 100 which is 16.8 then add 39.99 - 16.8 to get $23.19.

multiples of 8 = 1,2,4,8

multiples of 12= 1,2,3,4,6,12

Answer:

1/ 42% increased

2/ 62%

Step-by-step explanation:

Let's find the answer to the first question

Take 355 divided by 250, then times 100% = 142%

142% - 100% = 42% increase

So the percent increase is 42%

Now let's find the answer to the second question

First, find the total cost by 355 + 50 = $405

Take 405 divided by 250, then times 100% = 162%

162% - 100% = 62%

It increases by 62% if the airline charges ann additional $50 baggage fee!

The price of a box of candy will be $1.25.

And, Todd gets $20 and 5 boxes of candy.

Let price of box of candy = x

So, We can formulate;

⇒ $25 + x = $20 + 5x

Solve for x as;

⇒ $25 - $20 = 5x - x

⇒ $5 = 4x

⇒ x = 5/4

⇒ x = $1.25

The parabola has a minima, vertex and a y-intercept.

Given,

Since the equation is quadratic, the parabola has a vertex. To find it, do as follows:

x = -b/2a

Where:

a=1

b=-2

Then:

x = -(-2)/ 2 × 1 = 1

Substitute this into the equation to obtain y:

y = 1² - 2 × 1  + 3 = 2

The point of the vertex is (1,2)  

The sign of a is positive, therefore, the parabola has a minimum.

To find the height of a regular tetrahedron, you can use the formula h = sqrt(2/3) * s, where h is the height of the tetrahedron and s is the length of one of its edges. In this case, the length of one of the edges is 6 inches, so plugging this value into the formula gives:

h = sqrt(2/3) * 6 inches

= sqrt(4/3) inches

= sqrt(4/3) * sqrt(1/1) inches

= 2/sqrt(3) inches

To convert this to a decimal and round to the nearest hundredth, we can use a calculator to find that the height of the tetrahedron is approximately 3.46 inches.

What is binomial distribution?

A popular probability distribution known as the binomial distribution simulates the likelihood of getting one of two outcomes given a set of parameters. It totals the number of trials when each trial has an equal chance of producing a particular result. By dividing the quantity of independent trials by the number of successes, one can calculate the value of a binomial.

Let X has binomial distribution with n = 15 and  p = 0.20

The PDF of the distribution can be written as:

P(X=x)  = nCx(p)x (1-p)n-x

Probability for 0 patients have broken bones can be calculated as:

P(x=0) = 15C0(0.20)0 (1-0.20)15-0

P(x=0)  = 0.035184 = 0.0352
