Three of the four towns are on the vertices of the triangle ΔCBD, through
which the bearing can calculated.
<h3>Response:</h3>
- The bearing of D from B is approximately <u>209.05°</u>
<h3>Method by which the bearing is found;</h3>
From the given information, we have;
AC = AB = 25 km
∠BAC = 90° (definition of angle between north and east)
ΔABC = An isosceles right triangle (definition)
∠ACD = ∠ABC = 45° (base angles of an isosceles right triangle)
The bearing of <em>D</em> from <em>B</em> is the angle measured from the north of <em>B</em> to the
direction of <em>D.</em>
<em />
Therefore;
- The bearing of D from B ≈ 90° + (180° - 60.945°) = <u>209.05°</u>

Answer:
The answer is (b) ⇒
Step-by-step explanation:
∵
∵ √x² = x ⇒ that means to cancel the square root divide
the power by 2
∴
∵ √4 = 2 ⇒ √2×2 = √2² = 2
∵ √c³ =
∴
∴
∵ In the same base with multiplication we add the power,
in same base with division we subtract the power
∴
⇒
∴ The answer is (b) ⇒
The best answer would be A. 964.5. Hope this helps
You have to estimate the slope of the tangent line to the graph at <em>t</em> = 10 s. To do that, you can use points on the graph very close to <em>t</em> = 10 s, essentially applying the mean value theorem.
The MVT says that for some time <em>t</em> between two fixed instances <em>a</em> and <em>b</em>, one can guarantee that the slope of the secant line through (<em>a</em>, <em>v(a)</em> ) and (<em>b</em>, <em>v(b)</em> ) is equal to the slope of the tangent line through <em>t</em>. In this case, this would be saying that the <em>instantaneous</em> acceleration at <em>t</em> = 10 s is approximately equal to the <em>average</em> acceleration over some interval surrounding <em>t</em> = 10 s. The smaller the interval, the better the approximation.
For instance, the plot suggests that the velocity at <em>t</em> = 9 s is nearly 45 m/s, while the velocity at <em>t</em> = 11 s is nearly 47 m/s. Then the average acceleration over this interval is
(47 m/s - 45 m/s) / (11 s - 9 s) = (2 m/s) / (2 s) = 1 m/s²
Answer:
32.4 $
Step-by-step explanation:
25% off means he is paying 75% of the original price
Original price = 100%
75%=0.75=3/4
3/4 of 40 is 30
Apply 8% tax on amount of 30$ and add calculated value to 30$.
OR: you can think of 30 $ as 100%. You have to add 8% tax--. now you have 108%
108%=1.08
1.08*30=32.4
