Answer:
A. 16.55
Step-by-step explanation:
What we know is the angle of 38° and the hypotenuse is 21. Before we find x (side b), we have to find side a first. TO find that multiply the sine of 38 by 21.
21 * sin(38)
<em>sin(38) calculates to 0.615661475.</em>
21 * 0.615661475
<em>Multiply 21 by 0.615661475</em>
side a = 12.928890975
Now to find x. Use this to find x: √21² - 12.928890975²
√21² - 12.928890975²
<em>Square both numbers</em>
√441 - 167.156221843
<em>Subtract 167.156221843 from 441</em>
√273.843778157
<em>Find the square root of 273.843778157</em>
x ≈ 16.548225831
x ≈ 16.55, so the answer is A.
Answer:
The length of the tunnel is 7.66667 inch
Step-by-step explanation:
We are given
1 inch =60 miles
now, we can find for 1 mile
so,
60 miles = 1 inch
we get
we are given
total length is 460 miles
so, we can multiply both sides by 460
now, we can simplify it
So,
The length of the tunnel is 7.66667 inch
Answer:
See below
Step-by-step explanation:
y = -3 x^7 is NOT a parabola.... y = -3x^2 IS a parabola that opens downward due to the negative coefficient (-3)
The sequence is 2n if we're finding a pattern. multiply the previous number by 2 to get the next.
