Asher's sister is eight years older than
Asher. Their combined ages add up to 20.
How old is Asher?

Equation:


Solution:

Answers

You can make the equation by saying x is Asher’s age. Then

x + (x + 8) = 20

This simplifies to

2x = 12

And x = 6

Therefore, Asher is 6 years old

if 2+8=10 then 12+8=20 so Asher is 12 years old while His sister is 20 cus we're adding Ash age to his sister which we don't kno what her age is but at the same time we both know that whatever her age is it adds up to 20

A rectangular prism is made up of 320 unit cubes. The prism is 8 unit cubes wide.
Which could be the other dimensions of the rectangular prism? Choose all the possible dimensions.
A. 4 unit cubes long

B. 5 unit cubes long
8 unit cubes high
C. 8 unit cubes long
5 unit cubes high
D. 8 unit cubes long

F. 20 unit cubes long
2 unit cubes high
G. 20 unit cubes long
20 unit cubes high
H. 25 unit cubes long
15 unit cubes high

Answers

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.

What is a rectangular prism?

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.

Eliminate the parameter, t, in the parametric equations, x = 3cos(t) and y = -6sin(t).

A) 2 x2 + y2 = 36
B) x2 + y2 = 2
C) 4 x2 + y2 = 36
D) x2 + y2 = 36

Answers

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).

What are parametric equations?

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 domain and range of the functions are:

Function (A):

Domain: (-2, -1, 0, 2); Range:  -4

Function (B):

Domain: (-4, -2, 1, 4); Range: -8

What are domain and range?The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input. The difference between the lowest and highest values in a list or set is known as the range. Put all the numbers in order before determining the range. The lowest number should then be subtracted from the highest.

So, the domain and range of the function:

Function (A):

Domain: (-2, -1, 0, 2)Range: -2 -2 = -4

Function (B):

Domain: (-4, -2, 1, 4)Range: -4 -4 = -8

Therefore, the domain and range of the functions are:

Function (A):

Domain: (-2, -1, 0, 2); Range:  -4

Function (B):

How many ways can you arrange 2 letters from the word S Q U A R E

Answers

Answer:

30

Step-by-step explanation:

WE use permutation for this question:

since the letters in SQUARE are all distinct, so:

[tex]^{6}P_{2} = 6*5=30[/tex]

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

What are Combinations?

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

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.
