That depends on how accurate you are with pen and paper.

You can tell it's a growing exponential, so the form is the traditional one. If you are particularly inclined in crunching numbers and working on a grid I would pick 0, 1 and -1, 1/2 and -1/2, a few positive integers, and that's it.

If not, i would be satisfied saying that when x = 0 (ie, the y intercept) y= 3, and that's all. Then, my drawing is made with paint, don't expect a masterpiece.

Answer:36

Step-by-step explanation:36÷ -4 = -9

The answer would be 36 which is 36÷ -4 = -9 after applying the arithmetic operation.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

The quotient of a number and -4 is -9

Mathematically we can write:

x ÷ -4 = -9

x/(-4) = -9

x = 36

OR

36 ÷ -4 = -9

Thus, the answer would be 36 which is 36÷ -4 = -9 after applying the arithmetic operation.

Answer:

A, B, C, E, F.

Step-by-step explanation:

320 / 8 = 40

So the length times the  height of the prism  will be 40.

So the possible dimensions are

A ( 4 * 10).

B.

C.

E.

F

The option (A), (B), (C), (E), and (F) are correct because the multiplication of the length and height is 40.

It is defined as the six-faced shape, a type of hexahedron in geometry.

It is a three-dimensional shape. It is also called a cuboid.

We have volume of rectangular prism = 320 cubic unit

Width of the rectangular prism = 8 unit

320 = l×w×h

320 = 8l×h

l×h = 40

So the multiplication of the length and height should be 40

A. 4 unit cubes long and 10 unit cubes high:

l×h = 4×10 = 40

B. 5 unit cubes long and 8 unit cubes high:

l×h = 5×8 = 40

C. 8 unit cubes long and 5 unit cubes high:

l×h = 8×5 = 40

D. 8 unit cubes long and 8 unit cubes high:

l×h = 8×8 = 64

E. 10 unit cubes long and 4 unit cubes high:

l×h = 10×4 = 40

F. 20 unit cubes long and 2 unit cubes high:

l×h = 20×2 = 40

G. 20 unit cubes long and 20 unit cubes high:

l×h = 20×20 = 400

H. 25 unit cubes long and 15 unit cubes high:

l×h = 25×15 = 375

Thus, the option (A), (B), (C), (E), and (F) are correct because the multiplication of the length and height is 40.

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

Explanation:

This is a piecewise function that is composed of two parts:

This piecewise function has split identities or multiple aliases so to speak. It all depends on what the x input is.

The graph is shown below.

The domain is the set of all real numbers since any x value will lead to some y output. Even x = 0 itself is allowed. Note the arrows indicate the graph stretches on forever to the left and to the right.

The range on the other hand isn't all real numbers. Instead, it's [tex]y \le 6[/tex] indicating that y = 6 is the largest y can get. Simply locate the highest point on the graph (similar to the concept of the vertex) and you'll spot the highest y value.

Answer:

14/15

Step-by-step explanation:

9/15+5/15=14/15

3/5+1/3

common denominator is 15 ( just think about the 3 times table and 5 times table )

5*3=15

3*5=15

Multiply the denominator and numerator by 3 for 3/5

Multiply the denominator and numerator by 5 for 1/3

(3)(3)/(5)(3) +(1)(5)/3(5)

9/15+5/15= 14/15

Answer : 14/15

The expected number of a dataset is the mean of the dataset

The given parameters are:

[tex]\mathbf{n = 100}[/tex] --- sample size

[tex]\mathbf{r = 3}[/tex] --- selection of 3 people

(a) The expected number of birthdays

The probability of a having a birthday on a certain day is:

[tex]\mathbf{p = \frac{1}{365}}[/tex]

The probability of not having a birthday on the day is:

[tex]\mathbf{q = \frac{364}{365}}[/tex]

For a selection of 3 people in 100, the expected number of selection is:

[tex]\mathbf{E(x) =Days \times ^{100}C_3 \times p^3 \times q^{100 - 3}}[/tex]

So, we have:

[tex]\mathbf{E(x) = Days \times ^{100}C_3 \times \frac{1}{365}^3 \times \frac{364}{365}^{100 - 3}}[/tex]

Rewrite as:

[tex]\mathbf{E(x) =Days \times ^{100}C_3 \times \frac{1}{365}^3 \times \frac{364}{365}^{97}}[/tex]

There are 365 days in a year.

So, the expression becomes

[tex]\mathbf{E(x) =365\times ^{100}C_3 \times \frac{1}{365}^3 \times \frac{364}{365}^{97}}[/tex]

(b) Expected number of distinct birthdays

The probability that a person from the has his birthday on a certain day is:

[tex]\mathbf{p = 1 - (\frac{364}{365})^{100}}[/tex]

For 365 days, the expected number of distinct birthdays is:

[tex]\mathbf{E(x) = Days \times (1 - (\frac{364}{365})^{100})}[/tex]

There are 365 days in a year.

So, the expression becomes

[tex]\mathbf{E(x) = 365\times (1 - (\frac{364}{365})^{100})}[/tex]

Recall that

cos²(t) + sin²(t) = 1

Then solving for cos(t) and sin(t), we have

x = 3 cos(t)   ===>   cos(t) = x/3

y = -6 sin(t)   ===>   sin(t) = -y/6

so that the above identity gives us

(x/3)² + (-y/6)² = 1

x²/9 + y²/36 = 1

36 (x²/9 + y²/36) = 36

(C) 4x² + y² = 36

The parametric equation in the Cartesian form is 4x² + y² = 36 the correct choice is (C).

A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.

We have two parametric equations:

x = 3cos(t) and

y = -6sin(t).

As we know, the trigonometric identity:

sin²θ + cos²θ = 1

For checking the option (A):
2x² + y² = 36

= 2(3cos(t))² + (-6sin(t))²

= 18cos²t + 36sin²t ≠ 36

Similarly, for checking the option:

4x² + y² = 36

= 4(3cost)² + (-6sint)²

= 36cos²t + 36sin²t

= 36(cos²t + sin²t)

= 36(1) = 36

Thus, the parametric equation in the Cartesian form is 4x² + y² = 36 the correct choice is (C).

The number of ways of arranging 2 letters from the word S Q U A R E is given by A = 15 ways

The number of ways of selecting r objects from n unlike objects is given by combinations

ⁿCₓ = n! / ( ( n - x )! x! )

where

n = total number of objects

x = number of choosing objects from the set

Given data ,

Let the number of ways of arranging 2 letters from the word S Q U A R E be represented as A

Now , to select 2 letters from the 6 letters in the word SQUARE, without regard to order.

This is a combination problem, since the order in which we select the letters does not matter. Therefore, we can use the formula:

6 C 2 = 6! / 2!(6 - 2)!

= 6 x 5 / (2 x 1) x (4 x 3 / (2 x 1))

= 15
