A plane takes off at an angle of elevation of 15° and travels in a straight line for 3,000 meters. What is the height of the plane above the ground at this instant?

Answers

Answer 1

Answer: The angle of elevation is 15 degrees. This angle is measured from the horizontal. This problem requires us to review our triangle relationships. This triangle is a right triangle. That means to answer this problem we have to noe the relationship sin(angle) = opposite/hypotenuse. The 3000 is the hypotenuse measurement and we are to find the opposite. 3000sin(15) = 776.45m.

5 out of 10 marbles are bule
If the first marble is blue and is not replaced, there are 9 marbles left with 4 blue marbles
And therefore, the probability will be:

$(5)/(10)$ × $(4)/(9)$
= $(20)/(90)$
It can be simplified further:
= $(2)/(9)$

Let f(x) = x^2 – 81. Find f–1(x).
Can someone double-check what I have?

Answers

For the answer to the question above, if you are just checking your answer, I'll just show the solution. Is it just ok?
f(x) = x2 - 81
y = x^2 - 81
x = y^2 - 81
x + 81 = y^2
y = ± √(x + 81)

f⁻¹(x) = ± √(x + 81) answer

Answer is ±√x+81

I hope I helped you with my answer somehow.

I hope this helps you

y=x^2-81

x^2=y+81

x=square root of y+81

f^-1 (x)= square root of x+81

Taylor and Abby shared a $55 cash prize in the ratio 2:3. How much money did Taylor get?

Answers

the 2 to 3 ratio means there was 5 equal shares. because 2 plus 3 is 5

so if you divide 5 into 55 you get 11. each share is 11.

then multiply 11 by or 3 (depending on the person) in this case 2 because we want to know about Taylor

2 times 11 is 22.

Taylor got 22 dollars

If if x+y=10, find the value of y when x=3

Answers

Let me help you,

for this question, you know what is x and you wanna find the y.
So the only thing you should do is to put 3 for x and solve the equation:
3 + y = 10
y = 10 -3
y = 7

Hava great one!

Hey, Hardq!
The problem already gave us x. So we plug it in.
3+y=10
We now want to make the variable by itself, so we subtract 3 to the other side.
y=10-3
Simple Math
y=7
I hope this helps;)
