What is the positive solution to the equation 0=1/3x^2-3

1 answer:

3 0

Let's solve your equation step-by-step.0=13x2−3Step 1: Subtract 1/3x^2 from both sides.0−13x2 = 13x2−3−13x2−13x2 = −3Step 2: Divide both sides by (-1)/3.−13x2 − 13=− 3 −13x2 = 9Step 3: Take square root.x=±√9x=3 or x=−3Answer:x=3 or x=−3

In a circle an arc length 10 is intercepted by a central angle of 2/3 radius

djverab [1.8K]

We have been given that in a circle an arc length 10 is intercepted by a central angle of 2/3. We are supposed to find the radius of the circle.

We will use arc-length formula to solve our given problem.

$l=r\theta$ , where,

$l$ = Arc length,

$r$ = Radius,

$\theta$ = Central angle corresponding to arc length.

Upon substituting our given values in arc-length formula, we will get:

$10=r\cdot \frac{2}{3}$

$10\cdot \frac{3}{2}=r\cdot \frac{2}{3}\cdot \frac{3}{2}$

$5\cdot \frac{3}{1}=r$

$15=r$

Therefore, the radius of the given circle would be 15 units.

Help I don't understand this question that well

Romashka-Z-Leto [24]

1st) You would find the volume of the larger solid. V = Base Area • Height = (10•15) • 10 = 1500
2nd find the volume of the smaller figure. (2•4) • 4 = 32
Subtract the first from second 1500 - 32 = 1468.
Then you have to find the area of the fsces left after you took out figure two and add them to the total. 4•2 = 8. 4•2 = 8. 4•4 = 16
1462 + 16 + 8 + 8 = 1494 inches cubed
