Answer:
96 units^2
Step-by-step explanation:
area of a triangle A=bxh/2
substitute b with 8 and h with 24
A=8x24/2
multiply
A=193/2
the divide
A=96

Answer:</h3>
99.90%
<h3>
Step-by-step explanation:</h3>
STEPS:
- Find the total amount
- Find out what number of what we want to know the percentage of there are out of the whole amount there is. (Divide the percentage amount we want to find by the total amount)
- Turn into a percentage by multiplying by 100
Find the total sum
30.2 mil = 30,200,000 small businesses + 30,000 other = 30,230,000 total
Find the fraction that small businesses make up of the total
Convert to percentage
0.9990 → % = 0.9990 × 100 = 99.90%

A) To factor a quadratic equation, standard form is the better form to use because it is easier to pull out a common factor from.
b) To graph a parabola, it is better to use vertex form so that you will know what point to graph as the vertex of the parabola.
c) To identify the vertex, maximum and minimum, it is better to use vertex form because the vertex form will give the values of the coordinates for the vertex. Then, you can use the equation to find the mininmum or maximum. If the graph is negative, it will have a maximum because it points downward infinitely. If the equation is positive, the graph will have a minimum because the graph points upward infinitely.
d) Standard form is easier to use when trying to solve using the quadratic formula because it is easier to see what the coeffiecnts and constants are to plug in for a b and c.
