Answer:
a) 52.5 ft. b)40.1ft c)12.5ft d) 72.6
Step-by-step explanation:
a) The height of the lighthouse is 84ft, and the angle of elevation is 58 degrees.
tan58=84/x
find x by dividing 84 by tan58, and you get 52.5ft.
b) do the same thing, except 131 is in the base of the right triangle shape. That being said, do tan17=x/131.
multiply 131 by tan17, and you get x=40.1 feet.
c) This question wants you to find the length of the slide, (basically the hypotenuse).
given the angle to be 46, do sin46=9/x
since sin is opp/hyp
9/sin46= 12.5ft
d) Find the angle of elevation by using inverse tan given the base to be 5, and the height to be 16ft.
tan^-1=(16/5)=theta
x=72.6 hope this helps!
Given, a = -65 and b = 8.
We have to find multiplication of them.
a is negative and b is positive. When we multiply them, we know that the multiplication of positive and negative is negative. That means 
.
So 
= 
= 
= 
So we have got the required product.
Multiplication of a and b = -520.
The correct option is option C.
Answer:
c(h) = 40*h + 50
Step-by-step explanation:
Let h be the variable that represents the number of hours
As the cable operator charges $40.00 for an hour so for h hours, the expression will be 40*h
And
Lastly, he has to charge $50.00 must as service charge,
As the number of hours is variable here so the function will be in terms of hours.
So the resulting function will be:
c(h) = 40*h + 50
Okay so you have 10/12 marbles (ten out of twelve). Both 10 and 12 can be divided by 2, right? So divide both of those by 2 and you get 5/6. That’s your answer. Hope this helps!
The expression would me m / 7 or m and 7 as a fraction. M is on the top
