Answer:
the ship is at a distance of 60 feet
Step-by-step explanation:
we have to think of the problem as a right triangle, since
we have 2 legs and 1 hypotenuse, we know the measure of the leg that gives us the height and the angle that that leg touches
the leg we want to calculate is the opposite of the angle we have, since it does not touch
well to start we have to know the relationship between angles, legs and the hypotenuse
a: adjacent
o: opposite
h: hypotenuse
sin α = o/h
cos α= a/h
tan α = o/a
we see that it has (angle, adjacent, opposite)
is the tangent
tan α = o/a
tan 22 = o/150
tan 22 * 150 = o
60.6ft = o
round to the nearest foot
60ft
the ship is at a distance of 60 feet
I believe The answer is x=9
Answer:
Yes, this set of lengths can form a triangle.
Step-by-step explanation:
55+76 = 131
131 > 112
Since the sum of smaller lengths is greater than 112, these numbers can form a triangle.
The standard equation is 4p(x-h) = (y-k)^2 where |p| = focal distance |4p| = focal width.
<span>x=-1/8y^2
-8x=y^2
4*(-2)(x-0) =( y-0)^2
p = -2, h=0, k=0</span><span>
focal width = |4*(-2)| = 8
The answer to your question is that the length of the focal width is equal to 8.</span>
The expression above is composed of 3 terms which are: 3x, 2y, and 8z. All of the terms are the product of two items. The first term is a product of 3 and x. The second is a product of 2 and y. Lastly, the third is a product of 8 and z.
<span>Thus, the expression is a sum of three products and there are only three terms. This answer is the second among the four choices.
hope this helps : )
