Answer:
Step-by-step explanation:
Given
Length of curve

Length of curve is given by
over interval a to b
comparing two we get


integrating


Curve Passes through (1,2)


curve is

It is a down shift of 3.
Also written as (x, y-3)
The height of the water tank is 6.
L x W x H = V (volume)
15 x 10 x 6 = 900 cubic feet
Answer:
look at the horizontal line in the picture. the degree measure of any line is 180° given there's a perpendicular ray through that horizontal line it's therfore split into two sides both with angle measure of 90°.
given f is 71° then g can be found knowing that both g and f must add to 90°. 71+g=90. g=19°
now look at f again. f and d are what's known as vertical angles and that means that they're angle measures are congruent. therfore the measure of d is 71° d=71°
Finally to find e we notice that angle d and e form a straight line which means both angles measures must add to 180°. therefore e can be found by computing d+e=180
aunaitituitmg our information we know 71+e=180 then e must equal 109° e=109°
