Please answer it with solution :) 1. The radius of a solid sphere is measured to be (6.5 ± 0.2) cm. Determine the volume of the sphere with its uncertainty.

2. A resistor is marked as having a value of 5.9 ± 2%. The power P dissipated in the resistor, when connected in a simple electrical circuit, was to be calculated from the current in the resistor, which measured as (1.40 ± 0.05) mA. What is the value of calculated P together with its associated uncertainty?

3. A car accelerates uniformly from rest and travels a distance of (100±1) m. If the acceleration of the car is (6.5 ± 0.5) m/s², what would be its final velocity. together with its associated uncertainty, at the end of the distance covered?

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:  

1- c

2-a

mark brainliest!

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

answer: i think you should do the math and pay attention in class : )
