Answer:
-18v - 16
Step-by-step explanation:
6(2 - 7v) - 4(-6v + 7)
= 6×2 - 6×7v - 4×(-6v) -4×7
= 12 - 42v + 24v - 28
= -18v - 16
I'm assuming it's 10^6, so 10 would be the base, and 6 would be the exponent.
You have an angle of elevation of 3 degrees and you're 2000 ft from base of 30 story building.
<span>Draw a picture of this. Then tan(3) = ht of bldg/2000 </span>
<span>I get a height of 104.82 ft rounded to 2 dp. </span>
<span>5. Ok. use the Pythagorean Theorem here to find the hypotenuse of the right triangle </span>
<span>hypt = sqrt(50^2 + 9^2) </span>
<span>Now sine of the angle of elevation is 50/hypt. = 0.984 or 0.98 to 2 dp.</span>
Answer: $191.45
Step-by-step explanation:
This question requires the price of a bike in future so you can use the future value formula to calculate it:
Future value = Amount * (1 + rate)^ no. of periods
= 350 * (1 - 14%)⁴
= 350 * 0.54700816
= $191.45
<em>The rate is subtracted from 1 instead of being added to represent that the value is decreasing not increasing. </em>
