An aquarium is expanding its touch tank exhibit and is going to double the dimensions of the original tank. ​

​If the volume of the original tank was 2,000ft

, what is the volume of the new touch tank?

​

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

m∠a is 90°

m∠b is 40°

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
