Answer:

x=65

Step-by-step explanation:

Based on the given conditions, formulate: 157+3.75 X x=400.75

Rearrange unknown terms and Calculate the sum:

3.75x = 400.75 - 157

3.75x = 243.75

x=243.75 / 3.75

x=65

*PLEASE HELP WILL GIVE 60 POINTS I'M DESPERATE*

Zina [86]

Answer:

(0, 3)

Step-by-step explanation:

1. Find the slope:

$\frac{y_{2} -y_{1} }{x_{2}-x_{1} } =\frac{0-(-3)}{-4-(-8)}\\ \\=\frac{3}{4}$

2. Calculate the y-intercept using a given point:

(-8, -3)

-3 = $\frac{3}{4} (-8)$ + b

-3 = -6 + b

-3+6 = -6+6 + b

3 = b

3. Write in slope intercept form:

$y= \frac{3}{4} x+3$

Therefore, the y-intercept is 3.

The graph for this table is shown below.

hope this helps :)

Find the second derivative, do not have to simplify

zlopas [31]

$f(x)=\sec(\pi x)=\dfrac{1}{\cos(\pi x)}=[\cos(\pi x)]^{-1}\\\\\text{use}\\\\(a^n)'=na^{n-1}\\\\(\cos x)'=-\sin x\\\\f'(g(x))=f'(g(x))\cdot g'(x)$

$f'(x)=\left\{[\cos(\pi x)]^{-1}\right\}'=-[\cos(\pi x)]^{-2}\cdot[-\sin(\pi x)]\cdot\pi\\\\=\dfrac{\pi\sin(\pi x)}{[\cos(\pi x)]^2}=\pi\dfrac{\sin(\pi x)}{\cos(\pi x)}\cdot\dfrac{1}{\cos(\pi x)}\\\\=\pi\tan(\pi x)\sec(\pi x)$
