1. Factor out the greatest common factor (GCF). (There will not always be one). 2. Count the number of terms.
3. Check to be sure each factor is prime, if not, repeat 1-3.
4. Check by multiplying the factors out to see if you get the original polynomial.

The distance between points (X7, Yı) and (4, 8) is the square root of (x7 - 8)2 +

serious [3.7K]

Answer:

B. False

Step-by-step explanation:

Given

$Points: (x_7 - y_i),(4,8)$

Required

Is the distance between them $\sqrt{(x_7 - 8)^2 + (y_1 - 4)^2}$

Given that there are two points, the distance between them is calculated using

Distance = $\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$

In this case;

$(x_1,y_1)= (x_7 - y_i)\\(x_2,y_2) =(4,8)$

Substitute these in the given formula

Distance = $\sqrt{(4- x_7)^2 + (8 - y_1)^2}$

Comparing this with the given formula, both are not the same;

Hence, the formula is false and the correct formula is of the form $\sqrt{(4- x_7)^2 + (8 - y_1)^2}$

The point P on the circle x2 + y2 = r2 that is also on the terminal side of an angle θ in standard position is given. Find the i

Brut [27]

Okay so you do not really need the circle equation. if you make a triangle with it's x length as 3 and it's y length as 4, you will be able to find the third length. Do Pythagorean theorem to find the hypotenuse.
the hypotenuse will be five after you calculate it.

sin is opposite over hypotenuse or Y over R

so... the sin is 4/5

make sure you know what quadrant your triangle is in for the negatives

Last year the backgammon club had 30 members. This year the club had 24 members. Find the percent of decrease in the number of m

Gnom [1K]

There is 20% decrease in the number of members.

Step-by-step explanation:

Given,

Members last year = Old value = 30

Members this year = New year = 24

Change = New value - Old value

Change = 24 - 30

Change = -6

The negative sign indicates the decrease.

Decrease percent = $\frac{Change}{Old\ value}*100$

Decrease percent = $\frac{6}{30}*100$

Decrease percent = $\frac{600}{30}$

Decrease percent = 20%

There is 20% decrease in the number of members.

Sin2alpha+cos2alpha-cos6alpha/sin4alpha+2sin²alpha-1<br><br> if alpha is -135°

balandron [24]

Answer:

$= \frac{\sin(2 \alpha ) + \cos(2 \alpha ) - \cos(6 \alpha ) }{ \sin(4 \alpha ) + 2 { \sin }^{2} \alpha - 1} \\ = \frac{ \sin( - 270) + \cos( - 270) - \cos( - 810) }{ \sin( - 540) + 2 { \sin }^{2}( - 135) - 1 } \\ = \frac{1}{ - 2} \\ = - 0.5$
