Answer:
25.2294 feet
Step-by-step explanation:
We can solve this question drawing a triangle using the values given and then using the law of sines. (See image attached to know how to draw the triangle and use the values).
First we need to find the third angle of the triangle, that is, the angle in the vertix where the bird is:
y + 55 + 63 = 180
y = 62°
The relation between the angles and the distances are:
25 / sin(y) = x / sin(63)
25 / 0.8829 = x / 0.8910
x = 25 * 0.8910 / 0.8829 = 25.2294 feet
Answer:C
Step-by-step explanation:
Because the inverse only gets applied to what you are inputting in the parentheses of the function.
Answer:
24/121
Step-by-step explanation:
The probability of an event happening is the ratio of the number of possible outcome to the number of total outcome.
The probability of not getting green then green
= rg or bg
Where r is the probability of getting red, g is the probability of green and b is the probability of blue.
= 4/11 * 3/11 + 4/11 * 3/11
= 12/121 + 12/121
= 24/121
In 8 years you will be twice as old as your brother.
Right now, your brother is 4 years old, and 4 x 4 is 16, so you are 16.
In two years, your brother would be 6, and you would be 18, making you 3 times as old.
So, in 8 years, your brother will be 12 years old, making you 24. 12 is half of 24.
The solution is where the lines intersect.
They intersect at the point (0,-1)
x = 0
y = -1
