The volume of a sphere is a function of its radius,

jeka57 [31]

Hi there!

»»————-　★　————-««

I believe your answer is:

$6525\text{cm.}^3$

Keep in mind that this is APPROXIMATE.

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Volume of a Sphere Is:}}\\\\V = \frac{4}{3} \pi r^3\\----------------\\\rightarrow \text{We are given the radius of } 11.6\text{ cm.}\\----------------\\V = \frac{4}{3}(3.14) (11.6)^3\\\\V = \frac{4}{3}(3.14) 1560.896\\\\V \approx 6534.95125\text{cm.}^3\\\\\boxed{V \approx 6535\text{cm.}^3}$

i have posted this like 5 times so plz don't just pass it up. i need real help and i need it soon. i need help with Linear Equat

Gwar [14]

Example:

y = 2x + 1 is a linear equation:

When x increases, y increases twice as fast, so we need 2x
When x is 0, y is already 1. So +1 is also needed
And so: y = 2x + 1

Here are some example values:

x y = 2x + 1

-1 y = 2 × (-1) + 1 = -1

0 y = 2 × 0 + 1 = 1

1 y = 2 × 1 + 1 = 3

2 y = 2 × 2 + 1 = 5

-----------------------------------------------------------------------------

Each solution is a pair of numbers (x,y) that make the equation true. Solving a linear equation usually means finding the value of y for a given value of x. If the equation is already in the form y = mx + b, with x and y variables and m and b rational numbers, then the equation can be solved in algebraic terms.

i wish you the best <33

How to write the slope intercept form of the equation of the line through the given points?

Paha777 [63]

Slope intercept form of an equation is:
y = mx + b
where m is the slope and b is the t intercept.

First you must determine the slope of the line. This is a ratio of how fast the line travels up or down vs how fast it is moving to the right. Another name for this is rise over run. The equation to find the slope is:
m = (y1 - y2) / (x1 - x2)

now to find b. We can plug in one of the points of the equation into our first equation along with the slope to get out b value.

So if our 2 points were (2, 3) and (3, 4) we could find slope intercept form like this:
m = (2 - 3) / (3 - 4)
m = -1 / -1
m = 1
Now taking point (2, 3)
3 = 1 * 2 + b
1 = b
Finally to plug our m and b into equation for answer:
y = 1x + 1
However, 1 * anything is redundant therefore:
y = x + 1

A computer and printer cost total of $927 the cost of the computer is two times the cost of the planet find the cost of each ite

swat32

The cost of the printer is $309 and cost of the computer is $618.

Step-by-step explanation:

Let x denote the cost of computer

Let y denote the cost of printer

Total cost of printer and computer OR

x + y = $927

Cost of computer = 2 x cost of the planet

x = 2y

x+y = 927

2y+y = 927

3y = 927

y = 309

x = 2y

x = 2(309)

x = 618

Therefore, the cost of the printer is $309 and cost of the computer is $618.
