started with 225 added 75
225 +75 = 300 then added 200
300 +200 = 500, took 50 out
500-50 = 450 then added 125
450 +125 = 575
895-575 = 320
Answer is B $320
If Cos theta = 15/17, then
Sec theta = 17/15 because cosine and secant are reciprocal functions.
Letter A
Answer:
hello :
Hello : let A(1,0) B(0,2) in this line
the slope is : (YB - YA)/(XB -XA)
The second derivative at the point (2,2) is 34/9
<u>Explanation:</u>
<u></u>
2x⁴ = 4y³
2x⁴ - 4y³ = 0
We first need to find dy/dx and then d²y/dx²
On differentiating the equation in terms of x
dy/dx = d(2x⁴ - 4y³) / dx
We get,
dy/dx = 2x³/3y²
On differentiating dy/dx we get,
d²y/dx² = 2x²/y² + 8x⁶/9y⁵

d²y/dx² = 34/9
Therefore, the second derivative at the point (2,2) is 34/9
I think the answer is 18 because together, they are 26 meters and one is 8 so u have to subtract the total with 8 which is 26-8. the answer to that would be 18.
ANSWER: 18 meters
