A rectangle prism has dimensions of 2 cm x 2 cm x 5 cm what is its surface area explain your reasoning

Answers

The surface area of a rectangle prism is 48cm²
The volume of a rectangle prism is 20 cm³
A rectangular prism is a three-dimensional shape with six faces and twelve sides.
Volume of a rectangle prism = length x width x height
2 x 2 x 5 = 20 cm³
Surface area of a rectangle prism = 2 ( lw + wh + lh)
Where:
l = length
w = width
h = height
Surface area = 2 x [ (2 + 2) + (2 x 5) + (2 x5) ]
=2 x (4 + 10 + 10)
= 2 x (24)
= 48 cm²

fourth degree and a single zero of -3

Answers

The degree of a polynomial is the highest power of the polynomial.

The polynomial is [tex]\mathbf{P(x) = (x + 3)^4}[/tex]

The degree is given as:

[tex]\mathbf{n = 4}[/tex]

The zero is given as:

[tex]\mathbf{x = -3}[/tex]

Add 3 to both sides

[tex]\mathbf{x + 3= 0}[/tex]

From the question, we understand that the polynomial has a single zero.

So, the polynomial is:

[tex]\mathbf{P(x) = (x + 3)^n}[/tex]

Substitute 4 for n

[tex]\mathbf{P(x) = (x + 3)^4}[/tex]

Hence, the polynomial is [tex]\mathbf{P(x) = (x + 3)^4}[/tex]

Find the circumference of a circle with a radius of 7 centimeters. Use 3.14 as an approximation for pi . Round your answer to the nearest whole centimeter. Enter only the number.

Answers

Hi this is the answer and explaination

I'm sorry if it's incorrect

hope's it's help

The circumcenter of a circle with a radius of 7 cm is, 44cm.

What is circumference?

Circumference is the distance around the perimeter of a circular object. It is defined as the length of the circle that is found by multiplying the diameter of the circle by π (pi), which is approximately equal to 3.14.

The formula for the circumference of a circle is given by: C = 2πr,

Given that,

The radius of circle = 7 cm

Substituting the given value of radius as 7 and using pi = 3.14,

we get:

Circumference = 2 × 3.14 × 7

                         = 43.96

Rounding this to the nearest whole centimeter, we get:

Circumference ≈ 44

Therefore, the circumference of the circle with a radius of 7 centimeters is approximately 44 centimeters.

solve the system by elimination

x - y = -1
4x + 6y = -74

a) no solution

b) infinite number of solutions

Answers

9514 1404 393

Answer:

  one solution: (x, y) = (-8, -7)

Step-by-step explanation:

We can add 6 times the first equation to the second equation in order to eliminate y.

  6(x -y) +(4x +6y) = 6(-1) +(-74)

  10x = -80

  x = -8

  y = x+1 = -7 . . . . . solve the first equation for y; substitute x

The one solution is (x, y) = (-8, -7).

3x-2y=4
2x+3y=7

X=?
Y=?

Plz step by step

Answers

Answer:

x= 2

y= -1

Step-by-step explanation:

Simultanous equation(elimination method)

STEP 1: multiply the number near x with the opposite equation.

in this case in equation 1, three is near x so u multiply it with the second equation.

2(3x-2y=4)

3(2x+3y=7)

you get 6x-4y=8

6x+9y=21

STEP 2: Change the sign ONLY IN SECOND equation to its opposite sign

6x-4y=8 <-------- 1st equation

6x+9y=21 <-------- 2nd equation

SO WE CHANGE THE SIGN IN SECOND EQUATION TO: -6x-9y= -21

STEP 3: Now do the elimination part and calculation

+6x-4y=8

-6x-9y= -21

___________

0x-13y= 13

NOTE: X IS ALWAYS CANCELLED IF ITS NOT THERE'S PROBABLY A MISTAKE

STEP 4: Solve for y

now that x is cancelled we have to solve for y.. to do this take the eliminated equation in step 3 and solve for y

-13y= 13

y= 13/-13

y= -1

STEP 5: We have officially solved for y.. now we need to bother about x.. to solve for x take the first original equation IN THE QUESTION and substitiute( replace) y value in equation

ORIGINAL EQUATION: 3x-2y=4

3x-2(-1)=4

3x-2=4

x= 6/3

x= 2

NOTE: YOU CAN ALSO TAKE THE SECOND EQUATION BUT ITS EASIER WHEN YOU TAKE THE FIRST ONE. EITHER WAY YOU MUST GET THE SAME ANSWER

Answer:

x=2, y=1

Step-by-step explanation:

3x-2y=4

2(3x-2y)=2(4)

6x-4y=8

2x+3y=7

3(2x+3y)=3(7)

6x+9y=21

6x+9y-(6x-4y)=21-8

6x+9y-6x+4y=13

13y=13

y=13÷13

=1

3x-2y=4

3x-2(1)=4

3x=4+2

=6

x=6÷3

=2

Hence, x=2 and y=1.

A fair die is rolled 11 times. What is the probability of rolling a 4 on the die 4 times? Express your answer as a decimal rounded to 4 decimal places after the decimal point.

Answers

The probability of rolling a 4 on the die 4 times out of the total 11 times that it was rolled is; 0.0007716

How to solve probability?

We are given;

Number of times dice is rolled = 11

Now, on a die, there are 6 numbers and as such probability of getting a 4 is; P(getting a 4) = 1/6

Thus;

probability of rolling a 4 on the die 4 times = (1/6)⁴

⇒ 0.0007716

Answers

The statement "the square of the longest side is equal to the sum of the squares of the two shorter sides" is true for a right-angled triangle.

(a) 5 cm, 12 cm and 13 cm

The statement is represented as:

[tex]\mathbf{13^2 = 12^2 + 5^2}[/tex]

[tex]\mathbf{169= 144 + 25}[/tex]

[tex]\mathbf{169= 169}[/tex]

Hence, the statement is true for triangle (A)

(b) 4 cm, 5 cm and 7 cm

The statement is represented as:

[tex]\mathbf{7^2 = 5^2 + 4^2}[/tex]

[tex]\mathbf{49 = 25 + 16}[/tex]

[tex]\mathbf{49 = 41}[/tex]

Hence, the statement is not true for triangle (B)

(c) 3 cm, 4 cm and 5 cm

The statement is represented as:

[tex]\mathbf{5^2 = 4^2 + 3^2}[/tex]

[tex]\mathbf{25 = 16 + 9}[/tex]

[tex]\mathbf{25 = 25}[/tex]

Hence, the statement is true for triangle (C)

(d) 9 cm, 12 cm and 15 cm

The statement is represented as:

[tex]\mathbf{15^2 = 12^2 + 9^2}[/tex]

[tex]\mathbf{225 = 144 + 81}[/tex]

The value of Δy using the function y= 5x^3 as x goes from -2 to 1 is; Δy = 45

The question requests that Δy be computed according to the function, y = 5x³ as x goes -2 to 1.

Δy = y2 - y1

where:

y1 = 5(-2)³

y1 = -40

and

y2 = 5(1)³

y2 = 5

Therefore,

Δy = y2 - y1

Δy = 5 - (-40)

Δy = 45.
