Solve for x. Round your answer to 2 decimal places. (See image)

UNO [17]

Answer:

A. 32.08

Step-by-step explanation:

The figure given is a right triangle. We would apply trigonometric ratios formula to find x.

Reference angle = 58°

Hypotenuse = x

Adjacent length = 17

Thus, we would apply the following:

$Cos(\theta) = \frac{Adjacent}{Hypotenuse}$

Plug in the values

$Cos(58) = \frac{17}{x}$

Multiply both sides by x

$Cos(58) \times x = \frac{17}{x} \times x$

$Cos(58) \times x = 17$

Divide both sides by Cos(58)

$\frac{Cos(58) \times x}{Cos(58)} = \frac{17}{Cos(58)}$

$x = \frac{17}{Cos(58)}$

$x = 32.08$ (2 d.p)

Find the interval on which the curve of y equals the integral from 0 to x of 2 divided by the quantity 1 plus 3 times t plus t s

Hello,

$\dfrac{d^2( \int\limits^x_0 { \dfrac{2}{t^2+3t+1} } \, dt )}{dx^2} = \dfrac{d(\dfrac{2}{x^2+3x+1}) }{dx} \\

= \dfrac{-2(2x+3)}{(x^2+3x+1)^2}$
