Answer:
15 3/4t^2 + 5 1/4
Explanation:
h(t)=-16t^2+400
We can add 400 then - 64 and show as 8^2
= h(t)=-16t^2+400 - 8^2
But we also need to change 16t^2;
We divide 64 into 16 = 16/64 =0.25
and show 16t^2 changes by 0.25 = 1/4
15 3/4t^2 + 400-64
Can now look like
15 3/4t^2 + 5 1/4
As 5 1/4 = 64 x 5 1/4 = 336
If z = a-bi, the complex conjugate of z is a + bi.
So the imaginary part is "b"
"b" is opposite of -b, so correct answer is c)

Answer:
20.53 minutes
Step-by-step explanation:
Speed = Distance/Time = 30/7
Time = Distance / Speed
= 5280/30/7
= 1232 seconds / 60 = 20.53 minutes

Step-by-step explanation:
Pam and Erin want the gardens to be proportional.
<em>proprtional</em><em>-</em><em> </em><em>equal</em><em> </em>
Pams garden has a length of 16 and width of 12. To find the area of Pam's garden multiply the length by the width.
<em>16</em><em>×</em><em>12</em><em>=</em><em> </em><em>192</em><em> </em>
Now that we know the area of Pam's garden, we can set up and equation for Erin's garden. Since they have to be equal we know that Erin's garden should equal 192. Thus we solve for the length by dividing the width from the total.
<em>192</em><em>÷</em><em>21</em><em>=</em><em>9.14</em>
