Answer:
Step-by-step explanation:
Given a Parabola that intersects the x-axis at x=3 and x=9.
I presume you want to determine the equation of the parabola.
You can use this form:
Given roots of a parabola, the equation of the parabola is derived using the formula:
The equation of the parabola is:
Answer:perimeter
Step-by-step explanation:20+20+4=44 and u multiply 3/5x times 2 it equals 6/10x+44
If you would like to know the number of square feet of grass seeds that the lawn company can spread per hour, you can calculate this using the following steps:
7500 square feet ... 2 1/2 hours = 5/2 hours
x square feet = ? ... 1 hour
7500 * 1 = 5/2 * x
7500 = 5/2 * x /*2/5
x = 7500 * 2 / 5
x = 3000 square feet
The correct result would be 3000 square feet.
Since you are given that the triangle are similar, by definition of similar, we know that corresponding angles are congruent and corresponding sides are proportional.
The ORDER of the similarity statement is paramount.
Triangle ABC is similar to triangle EDC means that:
Angle A = Angle E
Angle B = Angle D
Angle C = Angle C
Angle B = 62 degrees so Angle D = 62 degrees.
