Answer:

any angle under 90 degrees is acute. A right angle is 90 degrees always, and obtuse angles are always above 90 degrees. Straight angles are always 180 degrees. A reflex angle is more than 180 degrees but less than 360 degrees. Hope this helps.

Find an ordered pair that satisfies the equation 81x + 18y = 9
ch4aika [34]

We can solve using y = 0 and solving for x.

81x + 18(0) = 9

81x = 9

x = 1/9

Therefore, the point (1/9, 0) sastisfies the equation.

Best of Luck!

Complete the system that models the heights of the ball and the receiver’s hands over time. h = -16t² 14t h = -16t² t
bogdanovich [222]

Answer: The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8

What is an equation?

An equation is an expression that shows the relationship between two or more variables and numbers.

A quarterback throws a football toward a receiver from a height of 6 ft. The initial vertical velocity of the ball is 14 ft/s. At the same time that the ball is thrown, the receiver raises his hands to a height of 8 ft and jumps up with an initial vertical velocity of 10 ft/s.

The height of the ball at time t is given as h = -16t² + 14t + 6 while the height of the receiver hand at time t is given as h = -16t² + 10t + 8

The base diameter and the height of a cone are both
WITCHER [35]

Answer:

11/ 42. *. X^ 2. * X = I/3 X A * h; if E = 1/3 A

Then the answer is EX

Step-by-step explanation:

Volume of cone= 1/3 * base area * height

= 1/3 * pi* (X/2)^2 * X

= 1/3. * 22/ 7 * X^3/4

= 22/ 21 * X^3 / 4

= 11/21 *. X^2/ 2. *. X

= 11/ 42. * X^3

= 11/ 42. *. X^ 2. * X
