Answer:

0.64

Step-by-step explanation:

Sine and cosine of angles are complimentary

This means

Sin x = Cos (90-x)

Cos x = sin (90 - x)

Therefore sin 40 = 0.64

Sin 40 = cos (90 - 40)

Sin 40 = cos 50

Cos 50 = 0.64

I hope this was helpful, please mark as brainliest

Answer:

a. Speed of flight * ( total spent away from hive - time stayed on flower bed)

b. The flower bed is 2,400 ft from the hive

Step-by-step explanation:

the speed * time taken

Given that he stays a total of 17 minutes away from the hive and he stayed 15 minutes in the flower bed, the time it used on the flower bed will be 17 minutes - 15 minutes = 2 minutes

So the distance from the flower bed to the hive is;

Speed of flight * ( total spent away from hive - time stayed on flower bed)

b. We want to find the distance of the flower bed from the hive

That will be;

20 ft per second * 2 minutes (120 seconds)

= 20 * 120 = 2,400 ft

Which shows the correct substitution of the values a b and c from the equation -2 equals negative X Plus x squared minus 4 into
kondor19780726 [428]
-2=-x+x square-4
firstly regroup the equation
x square-2x+x-2=0
x square-x-2=0
multiply the first term by the last term.(I.e x square multiply by -2=-2x square)
product of factor = -2x 1
sum of factor= -2x+1(x)= -1
x square -2x+x-2=0
open the bracket:
x(x-2)+1(x-2)=0
x=1 or x=-2
Therefore; x=-1 or x=2
