The equation below expresses the approximate

natka813 [3]

Answer:

The ball will be the 7 ft high at 2 different times.

Step-by-step explanation:

The height in meters of the ball is given by the following equation:

$h(t) = -16t^2 + 25t$

7 feet high

The height, by the equation, is given in meters, so we have to work in meters. Since each feet has 0,3048 meters, 7 feet have have 2.1336 meters. So, we have to solve the following equation

$2,1336 = -16t^2 + 25t$

$16t^2 - 25t + 2,1336 = 0$

At how many different times will the ball be 7 ft. High?

We have to find the number of solutions for the equation above.

It is given according to the value of $\Delta = b^2 - 4ac$ . If it is positive, there are two solutions, zero one solution and negative no solutions.

In this equation $a = 16, b = -25, c = 2.1336$ . So

$\Delta = b^2 - 4ac = (-25)^2 - 4*16*2.1336 = 488$

Since the coefficient is positive, the ball will be the 7 ft high at 2 different times.

Which set of three angles could represent the interior angles of a triangle? 49 degrees, 59 degrees, 72 degrees 34 degrees, 45 d

saw5 [17]

For this question you have to use the method of trial and error or guess and check

The interior angles of a triangle must add up to 180 degrees

Using this information, you have to check if any sum of three angles is equal to 180

The three angels that can be the interior angles of a triangle are 84, 72 and 24 (because they add up to 180)

6x/x+6<br> Find all real numbers for which the rational expression is undefined.

PtichkaEL [24]

Answer:

x=-6

Step-by-step explanation:

For the rational expression, 6x/(x+6) to be undefined, the denominator need to be 0, so x=-6 is the point at which the function is undefined.
