Answer:

The correct option is 1.

Step-by-step explanation:

It is given that the Samantha’s parents give her $10 per week. For each chore that she does not complete, she must repay her parents $1.

In each graph x axis represents the number of incomplete chore and the y-axis represent the amount she have.

It means if se complete all chore, then she have the total amount $10. So the coordinate of y-axis is (0,10).

For each chore that she does not complete, she must repay her parents $1, it means if the number of incomplete chore is 1 then shen have,

10-1=9

So the second point is (1,9).

So the function is in the form of,

y=10-x

Where x is the number of incomplete chore.

the total amount will zero if the number of incomplete chore is 10, so the x-intercept is (10,0).

Since the value of amounts decrease by 1 unit for each incomplete chore, therefore the slope of the line must be -1.

According to the x and y-intercepts we can say that the option 1 is correct.

The y-intercept (initial value) is 10 and it has a slope of -1, so this is the first graph.

Suppose an isosceles triangle abc has a=pi/4 and b=c=4. What is the length of a^2?
Zanzabum

The law of cosines states that, if \alpha is the angle between sides b and c,

a^2 = b^2+c^2-2bc\cos(\alpha)

So, plugging our values, we have

a^2 = 16+16-2\cdot 4\cdot 4\cdot\cos\left(\dfrac{\pi}{4}\right)

This is equal to

a^2 = 32-32\cdot\dfrac{\sqrt{2}}{2} = 32-16\sqrt{2}
