I think it will be 0.314 radian
The multiplication of the expressions 2i and (4 – 5i) is 10 + 8i. Then the correct option is D.
<h3>What is multiplication?</h3>
It is also known as the product. If the object n is given to m times then we just simply multiply them.
The expressions are 2i and (4 – 5i).
Then the product of the expression will be given as
2i (4 – 5i)
8i – 10i²
And we know that i² = -1
Then we have
8i – 10 (–1)
10 + 8i

Answer:
The distance to the top of the balloon is approximately 33.977 meters
Step-by-step explanation:
The (horizontal) distance from the hot air balloon from the observer, <em>l</em> = 30 m
The angle of elevation to the top of the balloon, θ = 28°
With the balloon standing upright, the distance to the top of the balloon, <em>d</em>, the height of the balloon, <em>h</em> and the horizontal distance to the balloon, <em>l</em>, form a right triangle, where;
d = The hypotenuse side
l = The leg adjacent to the reference (given) angle,
h = The leg opposite to the given angle, θ
By trigonometric ratios, we have;
From which we get;
The distance to the top of the balloon, <em>d </em>≈ 33.977 m
Answer:
Step-by-step explanation:
17x²y+8y³-4x²
it has no greatest common monomial factor.
V + 4 = -2(x - 1)
v + 4 = -2x + 2
v = -2x - 2. [ Final answer]
Hope this helps!
