Answer: 11.8 km

Step-by-step explanation:

The resulting figure is a right angled triangle shown below

$Apply the Pythagorean theorem to find out the magnitude of the resultant vector $A B$ in the triangle $A B C$ as follows -$$\begin{aligned}&A B^{2}=B C^{2}+C A^{2} \text { (Hypotenuse }{ }^{2}=\text { Base }^{2}+\text { Adjacent }^{2} \text { ) } \\&=7.4^{2}+9.2^{2} \\&=139.4 \\&A B=11.806777 \\&\quad A B \approx 11.8 \mathrm{~km} \text { (Rounded off to the nearest tenth) }\end{aligned}$

Given f''(x) = - 16 sin(4x) and f'(0) = - 4 and f(0) = - 2.<br><br> Findf(1) =

cestrela7 [59]

Answer:

The complete equation is $f(x) = \sin 4x -8\cdot x -2$ . $f(1) = -10.756$

Step-by-step explanation:

Let be $f''(x) = -16\cdot \sin 4x$ , we need to determine the formula of $f(x)$ by integrating twice:

$f'(x) = \int {(-16\cdot \sin 4x)} \, dx$

$f'(x) = -16\int {\sin 4x} \, dx$

We apply the following algebraic substitution in expression above:

$u = 4\cdot x$ and $du = 4\,dx$

$f'(u) = -4\int {\sin u} \, du$

$f'(u) = 4\cdot \cos u + C_{1}$

$f'(x) = 4\cdot \cos 4x + C_{1}$

We use the same approach to determine $f(x)$ :

$f(x) = \int {(4\cdot \cos 4x)} \, dx + \int {C_{1}} \, dx$

$f(u, x) = \int {\cos u} \, du + C_{1}\int \, dx$

$f(u,x) = \sin u + C_{1}\cdot x + C_{2}$

$f(x) = \sin 4x + C_{1}\cdot x + C_{2}$

If we know that $f'(0) = -4$ and $f(0) = -2$ , the integration constants are obtained below:

$4 + C_{1} = -4$

$C_{1} = -8$

$C_{2} = -2$

The complete equation is $f(x) = \sin 4x -8\cdot x -2$ . (Angles are measured in radians) Then:

$f(1) = \sin 4 - 8- 2$

$f(1) = -0.756-8-2$

$f(1) = -10.756$
