Answer:
The height of the hill is of 9.19 miles.
Step-by-step explanation:
Relations in a right triangle:
The sine of an angle is given by the measure of the opposite side divided by the hypotenuse.
The cosine of an angle is given by the measure of the adjacent side divided by the hypotenuse.
In this question:
Angle of 45º, and drives 13 miles. Due to the inclination, this represents the hypotenuse.
The height is the opposite side. So
We have that 
The height of the hill is of 9.19 miles.
#1:
Solve:
-5/12 x 8/13 = -40/156
-40/156 can both be divided by 4: 40 ÷ 4 = 10 & 156 ÷ 4 = 39
Your final answer is: Option 2, -10/39
#2
Solve:
3/8 x (-3/6) you can first simplify 3/6 into 1/2 so-- 3/8 x (-1/2) = -3/16
Your answer is: -3/16
I've solved two of them for you, can you solve the rest on your own? (Reply if you need more answers)
Answer:
It would have no solution, since if you do the algebra -3 does not equal to 1
I'm assuming which expression gives the same result as <span>∑^4
The choices are:
</span><span>i=0^(5)
(1/3)^i
</span>
The second option is correct since the first option is erroneous or makes little sense. The second option and the <span>∑^4</span> are geometric progressions which will account for each other when substituted together or one into another.
