Answer:
-1,3
Step-by-step explanation:
1 left and 3 up
2L + 2W = 610L = 2W + 20 Substitute the second equation into the first: 2(2W + 20) + 2W = 610 Solve for W. 4W + 40 + 2W = 6106W = 570W = 95 Use the second equation to solve for L
Answer:
f = tanx *i + y³*j
Step-by-step explanation:
F(x,y) = ??
Fx,y) = gradf
Then
f(x,y) = ∫ sec²x dx + ∫ 3y²dy
∫ sec²x dx = ∫ 1/ cos²x dx
By change of variables
if z = tan x then z = sinx/cosx
dz/dx = cosx*cosx - (-sinx*sinx) / cos²x
dz/dx = cos²x + sin²x /cos²x
dz/dx= 1 /cos²x
dz = dx/ cos²x
∫ 1/ cos²x dx = ∫dz = z = tanx
And ∫3*y² = y³
Then f = tanx *i + y³*j
1. Alternate exterior angles
So, C
2.
180 = 76 + 2x
104 = 2x
52 = x
So, B
4.
4a. No
4b. Yes
4c. No
4d. Yes
5.
180 = 35 + 35 + 2x
180 = 70 + 2x
110 = 2x
55 = x
So, C.
7.
12/8 = 30/y
Cross multiply
12y = 240
y = 20
So, C
8. Alternate interior angles
So, A
9.
A C and D
