Answer:
Step-by-step explanation:
1.) Get the equation in the form y = ax^2 + bx + c.
2.) Calculate -b / 2a. This is the x-coordinate of the vertex.
3.) To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.
1.) y = -x^2 - 10x + 24
2.) -(-10) / 2(-1) = -5
3.) y = -(-5)^2 - 10(-5) + 24
y = -25 + 50 + 24
y = 49

<h2>V=1/3 pie r^2h (Formula)</h2><h2>12×22/7=1/3×22/7×3^2×h</h2><h2>Eliminate 22/7</h2><h2>12=(9×h)/3</h2><h2>Make "h" the subject of the equation </h2><h2>h=36/9</h2><h2>h=4m</h2>
Between 1 and 10, only two numbers are divisible by 5, and those are 5 itself, and 10.
Those two possibilities, out of the total of ten possibilities, gives us a probability of 2/10
You can simplify that probability fraction by dividing the numerator and denominator by 2.
1/5
