Answer:

Table of values

$x \to y$

$0 \to -5$

$1 \to -2$

$2 \to 1$

$3 \to 4$

$4 \to 7$

$5 \to 10$

<em>See attachment for graph</em>

Step-by-step explanation:

Given

$y = 3x - 5$

Solving (a): Make a table

Considering the values of x from 0 to 5, we have:

When $x = 0$

$y = 3x - 5 \to 3 * 0 - 5 = -5$

When $x = 1$

$y = 3x - 5 \to 3 * 1 - 5 = -2$

When $x = 2$

$y = 3x - 5 \to 3 * 2 - 5 = 1$

When $x = 3$

$y = 3x - 5 \to 3 * 9 - 5 = 4$

When $x = 4$

$y = 3x - 5 \to 3 * 4 - 5 = 7$

When $x = 5$

$y = 3x - 5 \to 3 * 5 - 5 = 10$

So, we have:

$x \to y$

$0 \to -5$

$1 \to -2$

$2 \to 1$

$3 \to 4$

$4 \to 7$

$5 \to 10$

PLEASE HELP URGENT multiple choice algebra question:

Law Incorporation [45]

Answer:

an=29.7(1/3)^(n−1)

Step-by-step explanation:

The first term, a1, is 29.7.

The common ratio, r, is 9.9/29.7 = 1/3.

The generic explicit rule is ...

an = a1·r^(n-1)

Filling in the values you have gives the explicit rule ...

an = 29.7(1/3)^(n-1)

_____

Please note that parentheses on the exponent are essential. Without them, the expression has a different meaning entirely.

Approximate cos (12π/ 13) by using a linear approximation with f (x) = cos x.

Katarina [22]

First pick a value of $x$ close to $\dfrac{12\pi}{13}$ . You should be fine with $x=\pi$ .

The linear approximation of $f(x)$ at $x=c$ is given by

$f(c)\approx f(a)+f'(a)(c-a)$

where $x=a$ is some fixed value close to $x=c$ . You have

$f(x)=\cos x\implies f'(x)=-\sin x$

so

$f\left(\dfrac{12\pi}{13}\right)\approx f(\pi)+f'(\pi)\left(\dfrac{12\pi}{13}-\pi\right)$
$\cos\dfrac{12\pi}{13}\approx\cos\pi-\sin(\pi)\left(-\dfrac\pi{13}\right)$
$\cos\dfrac{12\pi}{13}\approx-1$

The actual value is closer to -0.9709, so the approximation is decent.
