He jumps form the platform with an initi8al upward velocity of 8 ft/s. Use the formula h t = −16 t 2 + 8t + 24, where h is his height above the water, t is the time, v is his starting upward velocity, and s is his starting height.

It means that you have more variables than equations—that multiple combinations of sag and tension could be compatible with what you know about the span length and the deck mass. Also known as underdetermined. But the sag/height of the bridge is usually known/set during the design process. Then the tension is calculated, and the …Study with Quizlet and memorize flashcards containing terms like Use the discriminant to determine the number of real solutions to the quadratic equation given below. −3⁢x^2 + 7⁢x − 8 = 0, Drag each number to the correct location on the image.

The softball is 3 feet above the ground when it leaves the pitcher’s hand at a velocity of 50 feet per second. If the softball’s acceleration is –16 ft/s2, which quadratic equation models the situation correctly? An equation that can be written in the form ax2 +bx+c = 0 a x 2 + b x + c = 0 is called a quadratic equation. You can solve a quadratic equation using the rules of algebra, applying factoring techniques where necessary, and by using the Principle of Zero Products. There are many applications for quadratic equations.

Example 11.6.2. Find the vertex and the extreme value of the function q(n) = − 3n2 − 5n + 3. Solution. Notice a = − 3, which means a < 0. Hence, q(n) is an downwards parabola and, from the definition, we expect q(n) to have a maximum value. Let's use the formula to find the vertex, where a = − 3 and b = − 5.The vertex of a quadratic equation is the minimum or maximum point of the equation.
