A circle is graphed with its center on the origin. The area of the circle is 144 square units. What are the coordinates of the x−intercepts of the graph? Round to the nearest tenth.

(6.8,0) and (-6.8,0)

Step-by-step explanation:

Area = 3.14 × r² = 144

r² = 45.8598726115

Equation of the circle

x² + y² = 45.8598726115

x intercept is when y = 0

x² = 45.8598726115

x = + - 6.7719917758

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}
