For (a) let x = 0 and solve
for (b) find the line of symmetry of the curve
for a parabola
<span>a</span><span>x2</span><span>+</span><span>b</span><span>x</span><span>+</span><span>c</span>
<span>the line of symmetry is</span>
<span>x</span><span>=</span><span>−b2a</span>
<span>when you get this value substitute it for the max height</span>
<span>(c) you need to find then the height is 0....</span>
<span>so let H(t) = 0 and solve for x... maybe the general quadratic formula is easiest...</span>
Answer: Simplify the real and imaginary parts of the expression.
Answer is: 8x^2 minus
0.5x + 25 is your equation, since 25 is just a one time thing.
Answer:
3/20
Question:
A farmer plants corn in 1/4 of his field. He plants white corn in 3/5 of the corn
section of his field. This situation is shown in the model. What fraction of the whole field is planted with white corn
Step-by-step explanation:
Portion of the field planted with corn = 1/4
Total corn planted = 1/4 of field
Portion of the corn section planted with white corn = 3/5
Total white corn planted = 3/5 of corn section
We need to find the portion of the total field planted with white corn
The fraction of the whole field planted with white corn would be the product of the fraction of Total corn planted and fraction of Total white corn planted
= 1/4 × 3/5
= 3/20
The fraction of the whole field planted with white corn = 3/20
Hi there!
In order to solve, we'll need to use the trigonometry function tangent, which is opposite/adjacent.
The side opposite the angle is h, our height.
The side adjacent the angle is 41.
The equation is:
tan(58) = h/41
After multiplying both sides by the tangent of 58, you get that the height is 66m.
