Answer:
B I personally think..
Step-by-step explanation:
Hi,
Use Differential Formula :
d(u(x) • v(x))/dx = u'(x) • v(x) + u(x) • v'(x)
at x = 1 :
d(u(1) • v(1))/dx = u'(1) • v(1) + u(1) • v'(1)
d(u(1) • v(1))/dx = -5 • 6 + 4 • -2
d(u(1) • v(1))/dx = -30 - 8
d(u(1) • v(1))/dx = -38
Hope this helped :)
Answer:
area - 120 cm
Step-by-step explanation:
Answer:
B. n + 17 = 26
Step-by-step explanation:
A and C are immediately out as they don't have "any number" in them. It cannot be D because it's "17 more than a number", not 26 more than a number. Thus, the answer is B.
<span>2x^2 + 3x – 54 = </span>(2x - 9) (x + 6), so A and F
Answer:
A = 70 mm²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = 
h (b₁ + b₂)
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = 10, b₁ = 10, b₂ = 4 , then
A = × 10 × (10 + 4) = 5 × 14 = 70 mm²
