What is the solution to this?

Ahat [919]

Answer:

$\frac{5}{4}$ $x^{4}$ + sinx + c

Step-by-step explanation:

using the power rule

∫(a $x^{n}$ ) = $\frac{a}{n+1}$ $x^{n+1}$ and ∫cosx = sinx

∫(5x³ + 2cosx )dx

= $\frac{5}{4}$ $x^{4}$ + 2sinx + c ( c is the constant of integration )

Given that triangle x y z is congruent to triangle n m l, the measure of angle x equals 20 degrees, the measure of angle m equal

Delvig [45]

A triangle has a total angle of 180 degrees. Since we know that angle X = angle N = 20 degrees and angle Y = angle M = 75 degrees, therefore angle Z or angle L is equal to:

angle L = 180 – 20 – 75

<span>angle L = 85 degrees</span>

Therefore w is:

angle L = 5 (w – 2)

5 (w – 2) = 85

w – 2 = 17

Find the equation of the line that is perpendicular to y = 1/4 x – 2 and passes though the point (5, –2).

zlopas [31]

$\textsf{Let y = ax + b the line we want to find.}$

$\textsf{We know that the slope of y = ax + b is the inverse of the slope of } \mathsf{ y = \frac{1}{4}x - 2.}$

$\textsf{Thus:}$

$\mathsf{a = \dfrac{1}{\frac{1}{4}} = 4}$

$\textsf{As y = 4x + b passes thought (5, -2):}$

$\mathsf{-2 = 4 \cdot 5 + b \Rightarrow 20 + b = -2 \Rightarrow b = -22}$

$\textsf{Hence the line y = 4x - 22 is perpendicular to }\mathsf{y=\frac{1}{4}x - 2}\textsf{ and passes for the point (5, -2).}$
