Answer:
the blind one
Step-by-step explanation:
Answer:
Set up your height equation, then factor or use quadratic formula to find when h(t)=0
Step-by-step explanation:
Your equation will be -16t^2+vt +h where v is the initial velocity and h is the starting height. Now either factor or quadratic equation, whichever is easier for you.
Remember that the ball is on the ground when h(t)=0 since that is the height. There will be two zeros, one is a negative number so would be before you kicked the ball, the other one will be when the ball comes back down.
Answer:
64 degrees
Step-by-step explanation:
Lets find the measure of the other angle in the other triangle with measures of 84 and 36.
Since there are 180 degrees in a triangle, we just add the other two angles and subtract from 180:
84 + 36 = 120
180 - 120 = 60
So the measure of the other angle in the other triangle is 60. Since there is a right angle we subtract 60 from 90
90 - 60 = 30
So the triangle with the missing angle has two angles with measures of 86 and 30. Now we add the measures and subtract from 180 again.
86 + 30 = 116
180 - 116 = 64
So the missing angle has a measure of 64 degrees
Answer:
10 -16 i
Step-by-step explanation:
given,
(3+ 4 i) + (7 − 20 i)
for the given complex number
if the number is added of subtracted the real part will add or subtract to the real part and imaginary will add or subtract to the imaginary part.
now
= (3+ 4 i) + (7 − 20 i)
= (3 + 7) + (4+(-20)) i
= 10 + (-16) i
= 10 -16 i
so, the given answer will be 10 -16 i
