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
![m=\sqrt{\left(4\cdot \frac{\sqrt{3}}{3}\right)^2+4^2}](https://tex.z-dn.net/?f=m%3D%5Csqrt%7B%5Cleft%284%5Ccdot%20%5Cfrac%7B%5Csqrt%7B3%7D%7D%7B3%7D%5Cright%29%5E2%2B4%5E2%7D)
![m=\sqrt{\frac{4^2}{3}+4^2}](https://tex.z-dn.net/?f=m%3D%5Csqrt%7B%5Cfrac%7B4%5E2%7D%7B3%7D%2B4%5E2%7D)
![m=\sqrt{\frac{64}{3}}](https://tex.z-dn.net/?f=m%3D%5Csqrt%7B%5Cfrac%7B64%7D%7B3%7D%7D)
![m=\frac{8}{\sqrt{3}}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B8%7D%7B%5Csqrt%7B3%7D%7D)
![m=\frac{8\sqrt{3}}{3}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B8%5Csqrt%7B3%7D%7D%7B3%7D)
Thus,
Therefore, option D is true.
The answer is 20.6 hope this helps
The minimum and maximum of the set alone is 25 and 60. The range of that 35. So, the number is not less than or more than 25 or 60.
The set in order:
25, 36, 48, 52, 60
The median is 48, so the number has to be less than 48. Let's see if the number may be less than 36.
36+48
84
42
So, the number is right between 36 and 48.
43.5×2
87
Let's subtract 48 from that
87-48
39
So, the mssing value is 39. Let's check.
25, 36, 39, 48, 52, 60
48+39
87÷2
43.5
So the missing value is 39.
Answer:
f(t) = 15 + 160 + 1
Step-by-step explanation:
it said that t= 4 and because the t is after the 40 you would times 40 by 4 to get 160. Then you add them all up and there you go you got your velocity and speed.
