Answer:
Question 3 of 10 The answer should be 7
Step-by-step explanation:
The reason is because if it is out of 100 7/100 is still 7%
<span> first, write the equation of the parabola in the required form: </span>
<span>(y - k) = a·(x - h)² </span>
<span>Here, (h, k) is given as (-1, -16). </span>
<span>So you have: </span>
<span>(y + 16) = a · (x + 1)² </span>
<span>Unfortunately, a is not given. However, you do know one additional point on the parabola: (0, -15): </span>
<span>-15 + 16 = a· (0 + 1)² </span>
<span>.·. a = 1 </span>
<span>.·. the equation of the parabola in vertex form is </span>
<span>y + 16 = (x + 1)² </span>
<span>The x-intercepts are the values of x that make y = 0. So, let y = 0: </span>
<span>0 + 16 = (x + 1)² </span>
<span>16 = (x + 1)² </span>
<span>We are trying to solve for x, so take the square root of both sides - but be CAREFUL! </span>
<span>± 4 = x + 1 ...... remember both the positive and negative roots of 16...... </span>
<span>Solving for x: </span>
<span>x = -1 + 4, x = -1 - 4 </span>
<span>x = 3, x = -5. </span>
<span>Or, if you prefer, (3, 0), (-5, 0). </span>
Answer:

Step-by-step explanation:
Answer:
(9×3)-6= 21
I'm sorry if im wrong
(y×x)-6=21
(^i don't know what that is)
Answer: There is descending of 8260 feet in altitude for all 4 balloons.
Step-by-step explanation:
Since we have given that
Number of hot air balloons = 4
Number of minutes = 7 minutes
Descending per minute = 295
So, Total change in altitude for all 4 balloons is given by
Hence, there is descending of 8260 feet in altitude for all 4 balloons.
