If the mass of the object is 900 g and the volume is 1,875 cm³. Then the density of the object is 0.48 g/cm³.
What is density?Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.
The mass and density relation is given as
Density = mass / volume
An object has a mass of 900 g and a volume of 1,875 cm³.
Then the density will be
Density = 900/1875
Density = 0.48 g/cm³
Then the density of the object is 0.48 g/cm³.

prove fermat's last theorem:no three positive integers a, b, and c satisfy the equation a^n + b^n = c^n for any integer value of n greater than 2
The proofing of Fermat's last theorem shows that y = a² - b², z = a² + b² and x = 2ab.
How to prove fermat's last theorem?The equation x² + y² = z². We can assume that x, y, and z are positive and relatively prime. Suppose that x is even. Then:
(z - y/2)(z + y/2) = (x/2)²
Hence,
(z - y)/2 = b²
(z + y)/2 = a²
Then, y = a² - b², z = a² + b² and x = 2ab.

Answer:
(s - t)(x) = 4x^2 - x - 5
(s + t)(x) = 4x^2 + x + 5
(s * t)(-1) = 16
Step-by-step explanation:
(s - t)(x) is simply the same as s(x) - t(x)
(s + t)(x) is simply the same as s(x) + t(x)
(s * t)(x) is simply the same as s(x) * t(x)
(s - t)(x) = s(x) - t(x) = 4x^2 - (x+5) = 4x^2 - x - 5
(s + t)(x) = s(x) + t(x) = 4x^2 + (x+5) = 4x^2 + x + 5
(s * t)(-1) = s(-1) * t(-1) = 4(-1)^2 * (-1+5) = 4 * 4 = 16

Hayden said the expression 3(2x+1) will always be greater than 3 because when I distribute the 3 to the numbers inside the parentheses, I will multiply 3 and 1 which is 3 since I will always be adding to the first part of the expression the final answer must be greater than 3
Answer:
9x.Step-by-step explanation:
Hayden is correct. 3(2x + 1) = 9x.
Here is explanation:
If you didn't know, 2x + 1 would simply be 3x.
So then, 3 * 3x would then be 9x.
Here is math explanation:
3(2x + 1)= 3(3x)= 3 * 3x= 9x.You now have your answer!

Answer:
No, because the friend counted a length that is inside of the polygon, which you don't need for finding the perimeter, since the perimeter is the sum of the outside lengths of the polygon.

what y-value corresponds to an x-value of 3pi/2
Answer: THE ANSWER ON ACELLUS IS -1
Step-by-step explanation:
I found this answer on a site used to do sin cos and tangent
The y-value corresponding to an x-value of [tex]\( \frac{3\pi}{2} \)[/tex] in the function [tex]\( y = \sin(x) \) is \( y = -1 \).[/tex]
To find the y-value corresponding to an x-value of [tex]\( \frac{3\pi}{2} \)[/tex] in the function [tex]\( y = \sin(x) \),[/tex] simply substitute [tex]\( x = \frac{3\pi}{2} \)[/tex] into the function:

Now, let's evaluate the sine function at [tex]\( \frac{3\pi}{2} \):[/tex]
[tex]\( y = \sin\left(\frac{3\pi}{2}\right) = -1 \)[/tex]
So, the y-value corresponding to an x-value of [tex]\( \frac{3\pi}{2} \)[/tex] in the function [tex]\( y = \sin(x) \) is \( y = -1 \).[/tex]

In the whole number 70,819 the place value of the digit 1 is
Step-by-step explanation:
a number is a sequence of digits with every position being multiplied by increasing powers of 10.
and the whole number is then the sum of of these little multiplications.
the first position left of the decimal point is for 10⁰ (1). the second position is 10¹ (10). the third position for 10² (100). and so on.
the given number is therefore just the short version of
7×10⁴ + 0×10³ + 8×10² + 1×10¹ + 9×10⁰
and therefore, the digit 1 in this number has the value 1×10¹ = 10, which is also the place value, 10¹ = 10.

Find the equation of the line of the given properties: Slope = 0 and passes through (-4,5).
Pls help me
Answer:
y = 5
Step-by-step explanation:
An equation can be written in two forms: point-slope form or slope-intercept form.
When you write an equation in point-slope form, you only need two things: a point and a slope.
Given:
point: (-4, 5)slope (m): 0The standard point-slope equation is
y - y₁ = m(x - x₁)
Plug in what you know.
y - (5) = 0(x - (-4))
Simplify.
y - 5 = 0(x + 4)
y - 5 = 0
y = 5
This is your equation.
Let's now represent this in slope-intercept form.
The standard equation is
y = mx + b
Plug in what you know.
5 = 0(-4) + b
Simplify.
5 = 0 + b
5 = b
Therefore,
y = 0x + 5 or y = 5
Hope this helps!

how do I simplify the following to "a+bi" form: (1+2i)^3
Answer:
Expand it.
(1+2i)^3 is equal to (1+2i)(1+2i)(1+2i).
Multiply everything out (being sure to multiply every term. (1+2i) * (1+2i) = 1+2i+2i+4i^2.
i is the square root of negative one, so i^2 is just -1. 1+2i+2i-4 is what you get from the first two, so now simplify that:
1-4 + 2i+2i = (-3+4i) and now multiply that by (1+2i):
(-3+4i) * (1+2i) = -3 - 6i +4i +8i^2.
Simplify again, and the answer is: -11-2i
Step-by-step explanation:
I hope this helps - really my only tip is don't spend time thinking about what i is, that just hurts your brain. Just remember that i^2 is equal to negative one, and treat it like regular multiplication and you will be fine.

use a formula to find the surface area of the cylinder use 3.14 for pi
Answer:
376.8 cm²
Step-by-step explanation:
Given:
Radius of circular base: 4 cmHeight of cylinder: 11 cmSurface area = 2πrh + 2πr²
[Where "r" and "h" represents the radius and the height respectively]
Let's substitute the height and the radius in the formula and simplify it.
[tex]\implies 2\pi rh + 2\pi ^{2}[/tex]
[tex]\implies 2\pi (4)(11) + 2\pi (4)^{2}[/tex]
[tex]\implies 2\pi (44) + 2\pi (16)[/tex]
[tex]\implies 88\pi + 32\pi[/tex]
We can factor π out of the expression. Therefore, we get:
[tex]\implies 88\pi + 32\pi[/tex]
[tex]\implies \pi (88 + 32)[/tex]
Now, simplify the expression inside the parentheses.
[tex]\implies \pi (88 + 32)[/tex]
[tex]\implies \pi (120)[/tex]
The value of π, we are given, is 3.14. When substituted, we get:
[tex]\implies \pi (120)[/tex]
[tex]\implies 3.14(120) = 31.4(12) = \boxed{376.8 \ \text{cm}^{2} }[/tex]
Therefore, the surface area of the cylinder is 376.8 cm².
