Answer:

Quadrant 1 is the top right side. Quadrant 2 is top left. Quuadrant 3 is bottom left. Quadrant 4 is bottom right.

Step-by-step explanation:

<h3>You must mark the number on the quadrants starting by the middle is the axis (0). Then you count from 1 to how ever much the quadrants end. There the y axis and the x. Those are the lines that seperate the 4 quadrants. Quadrant 1 is both postive #. quadrant 2 is a negative number and a postive. depending on how the x and y are. the X axis is spostive the y is negative. Point A is (10,4) and its quadrant is 4. You must count all the boxes which go all the way up to 10. You must start in the center then either go up for Y or down. Go right or left for X. B is -8,9</h3><h3></h3><h3>I hope this helped. It took me a long time. </h3>

$\sf{\pmb{ANSWER : }}$

let the equation be

$\sf \: 3(y + 3) - 10 = 2y + 1$

$\sf \: 3y + 9 - 10 = 2y + 1$

$\sf \: 3y - 1 = 2y + 1$

$\sf \: 3y -2y = 1 + 1$

$\purple {{{\sf y = 2 }}}$

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

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

Find the area of the figure shown. Use 3.14 to approximate pi

Nina [5.8K]

Alrighty

we gots 1/4 circle and paralellogram

area circle=pi times radius^2
area paralelogram=base times height

1/4 circle is
radius is 10 so
area part circle is 1/4 times pi times 10^2=100/4pi=25pi=78.5 m²

area paralllogram is
10 times 3 because 3 is height and 10 is base length or 30

30+78.5=108.5 m² is the area
