Answer:
option D is true.
Step-by-step explanation:
The right-angled triangle is shown.
From the right-angled triangle,
The angle Ф = 60°
We know that the trigonometric ratio
tan Ф = opposite / adjacent
Thus,
tan 60 = 4 / n
√3 = 4/n
n = 4/√3
Thus,
n = 4/√3
= (4 × √3) / (√3 × √3)
= 4√3 / 3
Thus,
n = 4√3 / 3
Using Pythagorean theorem
m = √n²+4²





Thus,
Therefore, option D is true.
Answer:
14/20 or simplified 7/10 it can also be shown as 70% or 0.7 or 0.70

Answer:
Range = (-<em>∞, 5</em>)
Step-by-step explanation:
This is the absolute value function with transformation.
The parent function is f(x) = |x|
This function has a "negative" in front, so it makes it reflect about x axis
The -4 after x makes horizontal translation of 4 units right
the +5 at the end makes the function translate 5 units UP
<em>The graph is shown in the attached picture.</em>
<em>Looking at the graph, we can clearly see the range. The range is the allowed y-values. Hence, we can see that the </em><em>range is -infinity to 5</em>
<em />
<em>answer is not properly given, so i can't choose from the options, but the answer is -∞, 5 to 5</em>
Answer:
2nd is correct
Step-by-step explanation:
ok now mark me brainlist
F(t) = (t^-1) - t
Taking derivative:
<span>f'(t) = d/dt(t^-1) - t) = d/dt(t^-1) - d/dt(t) </span>
<span>f'(t) = -1(t^-2) -1
= -t^-2 - 1 </span>
<span>f'(t) = v(t),
It can be also written as :
-1/t^2 - 1 </span>
<span>So v(3) = -1/(3^2) - 1 = -1/9 - 1 = -10/9</span>
