Answer:
C. x = 3.71
Step-by-step explanation:
4 + 9(ln x) = 15.8
Subtract 4 from both sides.
9(ln x) = 11.8
Divide both sides by 9.
ln x = 11.8/9
x = e^(11.8/9)
x = 3.71
Your answer would be B. An elevation at sea level
This is because if you picture it like a grid, -20 on the y axis is below 0, and 0 on the y axis is the y axis, so it would be on sea level.
I hope this helps!
Answer:
18 in^2
Step-by-step explanation:
<em>1 )The three sides of the gutter add up to 12</em>
2x+ y = 12
<em>2) Subtract 2x from both sides. </em>
y = 12 — 2x
<em>3 )Find the area of the rectangle in terms of x and simplify.</em>
Area = xy = x(12 — 2x) = -2x^2+12x = f(x)
<em>4 ) x=-b/2a</em>
<em>x co-ordinate of the vertex= -12/2(-2)=3</em>
<em>5 )Plug in 3 for x into they equation.</em>
y co-ordinate of the vertex= 12 — 2(3) = 6
<em>6 ) Plug in 3 for x and 6 for y. </em>
Area= xy = 3(6) = 18
RESULT
18 in^2
Answer:
47 degrees
Step-by-step explanation:
A shape always adds up to 180 so I added the two degrees and subtracted it from 180. You get the answer 47
