Answer:
508,364
Step-by-step explanation:
just add them together :)
The first one is D) 6
then the second is C).
<span>it is an implicit function, (for high school students)
1) d(4x2+y2)/dx=d(48+2xy)/dx, after the differentiation, we obtain
8x + 2y .dy/dx = 2y + 2x .dy/dx
</span>8x - 2y = 2x .dy/dx - 2y .dy/dx, 4x - y = (x .- y ).dy/dx, and then
dy/dx = y-4x / y - x
2) when x cordinate is 2
we have 4(2^2) + y^2 = 48 + 2 . 2 y, and the y^2 - 4y - 32=0, after solving the quadratic equation we find y = - 8, or y = 4, this the positive y coordinate, the answer is y = 4
3) Let be P (xp, yp) the point, since P is the point at which the line tangent to the curve at P is horizontal, so we can write 4xp2+yp2=48+2xpyp, but xp=2, we have yp^2 - 4yp - 32=0, so P(2, 4)
Answer:
THE TREE IS 30.25 FEET TALLER THAN FRANK
Step-by-step explanation:
We can calculate the height of tree by this way,
Let h be the height of tree.
h = 35.75
The tree is 35.75 feet taller.
Now ,
35.75 - 5.5 = 30.25 feet
∴ THE TREE IS 30.25 FEET TALLER THAN FRANK
Answer:
A) Neither
Step-by-step explanation:
If two lines have same slope then they are parallel lines
If slope of line1* slope of line 2 = -1
The the two lines are perpendicular
In this question slope of line = 2\7
Slope of line 2 = 7\2
