ANSWER

EXPLANATION
The given function is

We take natural log of both sides;

Recall and use the product rule of logarithms.

This implies that:


We now differentiate implicitly to obtain;

Multiply through by y,

Substitute y=x²cosx to obtain;

Expand:


I used the Pythagorean formula, which is a² + b² = c².
a² and b² are the two side legs while c² is the hypotenuse.
One of the side is 42 - 8 = 34 cm.
Answer:
400 square inches
Step-by-step explanation:
surface area= summation of area of all the faces the object has
out object has 2 triangular faces, and 3 rectangular faces
S.A = 2(0.5bh) + LW +LW+LW
= 2(0.5 x 8 x 15) + (15x7) + (17 x 7) + (7×8)
= 120+105+119+56
= 400 square inches
( y1 - y2 ) / ( x1 - x2 )
In this case, I calculated it to be 12/10, or 6/5
Next, we choose a point to use in our formula. I'll use point E since it does not have any negative signs.
The final slope-intercept equation is then:
y - 8 = 6/5 * ( x - 4 )
