A rectangle airstrip measures 32.10 m by 280 m, with the width measured more accurately than the length. find the area (in m^2), taking into account significant figures

The functions ¢1(x) and ø2(x) are normalized: d φ( (α) φι(α) dx 0(x) 62(x) = 1 = 1 -00 -00 and are mutually orthogonal dx oi(x) $2(x) dx 4i(x) $1(x) = 0 . Is the function b_(x) = ¢1(x) – $2(x) normalized? If not, determine its normalization constant and write the formula for the normalized y_ (x). Is the function +(x) = ¢1(x) + ¢2(x) %3D orthogonal to _(x)?

Vector u = <-7,3,-5> and vector v = <-1,1,0>. Find u X (-9v)

If a number x is raised to some power n then the relative error in the result is |n| times the relativeerror in x,δ(xn)xn = |n|(δxx ), where the vertical lines denote the absolute value of the exponent.

Let X (capital x) = (m1x1 + m2x2)/(m1 + m2).  Calculate d2X/dt2, and simplify your expression as much as possible.

The vector B⃗ is added to a vector C⃗ given as C⃗ = −3i ^ + j ^. The resultant vector obtained as a result of this process is R⃗ = B⃗ + C⃗. The resultant vector is in the positive y direction and the size of this vector is equal to the size of the B⃗ vector (| R⃗ | = | B⃗ |). According to what is given; a-) What is the size of the B⃗ vector? b-) What is the angle between the vector B⃗ and the vector C⃗?
