If f(x)=2x+1 and g(x)=x^2+7, which of the following is equal to f(g(x))
topjm [15]

Answer: 2x^{2} +15

Explanation:

so basically f(g(x)) is telling you to plug the entire g(x) equation into x in the f(x) equation so it will look like this

2(x^{2} +7) + 1

and then simplify

2x^{2} +14 + 1

2x^{2} +15

What is the approximate length of the diameter, d? 40 ft 80 ft 125 ft 250 ft.
larisa [96]

The approximate length of the diameter,d of the circle is 250 ft

<h3>How to find the diameter of a circle</h3>

Circumference of the circle = 250π

  • Circumference of a circle = 2πr

250π = 2πr

  • divide both sides by 2π

250π / 2π = r

125 = r

Recall,

Radius, r of a circle = Diameter, d ÷ 2

125 = d/2

d = 125 × 2

d = 250

Therefore, the diameter of the circle is 250 ft

Svetlanka [38]

The Earth is known as a spherical body. The force of gravity of the Sun on Earth in June compared to December is  slightly smaller.

  • Earth is simply known to slightly closer to the Sun on one side of its orbit than on the other side.

Kepler's second law states that as a planet moves round the Sun, it sweeps out equal areas in equal times.

All the planets do moves around the Sun in nearly the same plane. The Sun is found to be slightly off-center from the middle of each planet's orbit.
