A fan blade spins at a constant rate. This spinning is known as revolutions. The equation y=750x represents the number of revo

Aneli [31]

Answer:

(0,0)

(1, 750)

(2, 1500)

(3, 2250)

Step-by-step explanation:

To list the ordered pairs (x,y) we need to calculated the number of revolutions for minutes 0, 1, 2 and 3.

To calculated the number of revolutions for 0 minutes, we need to replace x by 0 in the initial equation and solve for y as:

y = 750*x

y = 750*0

y = 0

It means that our first ordered pair is (0,0), because when we replace x by 0 we get y equal to 0

At the same way, if we replace x by 1, we get:

y = 750*x

y = 750*(1)

y = 750

So, our second ordered pair is (1, 750)

Then, replacing x by 2, we get:

y = 750*x

y = 750*(2)

y = 1500

So, our third ordered pair is (2, 1500)

Finally, replacing x by 3, we get:

y = 750*x

y = 750*(3)

y = 2250

So, our last ordered pair is (3, 2250)

So I'm stuck on a math problem. Given z=3 + 5i and w= -5 +I, evaluate z-w

skad [1K]

Answer:

8 + 4i

Step-by-step explanation:

Put corresponding terms above each other and subtract in the usual way.

z = 3 + 5i

z - w = 8 + 4i: 3 - (-5} = 8; 5i - 1i = 4 i

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:

⸻⸻⸻⸻

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

Points are: A= (-2,7)B= (3,5)C= (1,0) To show that the triangle is a right triangle, show that the sum of the squares of the len

Gala2k [10]

The sum of the squares of the lengths is 58

The square of length of the hypotenuse is 58

From the question, we have

AB² = (-2-3)² +(7-5)²= 25+4 =29

BC² = (3-1)²+(5-0)²=4+25=29

AC² = (-2-1)²+(7-0)² = 9+49 = 58

Here we can see that,

AB²+BC² = AC²

The sum of the squares of the lengths of two sides (the legs) equals the square length of the third side (hypotenuse).

the sum of the squares of the lengths = AB²+BC² =29+29 = 58

the square of length of the hypotenuse= 58

Pythagoras Theorem:

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side. When the positive integer sides of a right triangle (let's say sides a, b, and c) are squared, the result is an equation known as a Pythagorean triple.
