According to the graph, what is the value of the constant in the equation

love history [14]

Answer:

The value of the constant is 3

Step-by-step explanation:

Let

y ----> the height

x ----> the width

we have

$y=kx$

This is the equation of a linear direct variation

The equation of the line passes through the origin

we have the points

(0.5,1.5), (2,6) and (3,9)

see the attached figure to better understand the problem

Find the value of the constant of proportionality k

$k=\frac{y}{x}$

For (0.5,1.5) ----> $k=\frac{1.5}{0.5}=3$

For (2,6) ----> $k=\frac{6}{2}=3$

For (3,9) ----> $k=\frac{9}{3}=3$

therefore

The value of k is equal to 3

The linear equation is

$y=3x$

$Height=3Width$

Sam used his calculator to find cos 1.75. he wrote down cos 1.75 = .999. how could sam recognize that his answer is incorrect?

ZanzabumX [31]

Answer:

Step-by-step explanation:

Since π=3.14 and 1.75 should be half of π so cos(1.75) should be in the approximation of $\frac{\sqrt{2}}{2}$ or $0.7$ .

Clearly Sam's calculator is in the degree mode since $cos(1.75^{\circ})$

is about $.999$ and obviously, $\frac{{\pi}}{2}$ , So on the unit circle, it will be in the second quadrant.

Thus, cos(1.75) is negative.
