In the diagram, the chords AB and CD intersect inside the circle at point P. The equation that best answers the question above is AP x PB = CP x DP. Since, the line segment AB is bisected, the equation can be further reduced into,
                               AP² = CP x DP
Thus, the answer is letter D.

Suppose a kite has two congruent angles of 100°. Of the remaining angles, one is four times larger than the other. What is the m
Pani-rosa [81]

Answer:

The measure of the largest angle in the kite is 128 degrees

Step-by-step explanation:

we know that

The sum of the interior angles in any quadrilateral must be equal to 360 degrees

A kite is a quadrilateral

Let

A,B,C and D the measure of the interior angles

so

A+B+C+D=360^o

we have that

A=B=100^o

substitute

100^o+100^o+C+D=360^o

C+D=160^o ----> equation A

Remember that

one is four times larger than the other

so

C=4D ----> equation B

substitute equation B in equation A

4D+D=160

solve for D

5D=160\\D=32^o

Find the measure of angle C

C=4(32)=128^o

therefore

The measure of the largest angle in the kite is 128 degrees

Evaluate this expression for a = 3 and b = 4.
ahrayia [7]

Answer:

14

Step-by-step explanation:

a = 3

b = 4

b(a + 4)-3(3 + 2)+3 - 2\\a = 3,b=4\\4(3+4)-3(5)+3 - 2\\4(7)-15+3 - 2\\28-14\\\\14

The table below represents the closing cost of ABC for the last 5 days. What is the r -value of the linear regression that fits
Gnoma [55]

Answer:

The correct option is D.

Step-by-step explanation:

The linear regression equation is in the form of

y=bx+a

Where,

b=\frac{n(\sum xy)-(\sum x)(\sum y)}{n(\sum x^2)-(\sum x)^2}

a=\frac{(\sum y)(\sum x^2)-(\sum x)(\sum xy)}{n(\sum x^2)-(\sum x)^2}

The formula of r is

r=\frac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{[n(\sum x^2)-(\sum x)^2][n(\sum y^2)-(\sum y)^2]}}

The values are

\sum x=15,\sum y=98.91,\sum x^2=55,\sum y^2=1957.8295,\sum xy=293.78, n=5

Using above formula, we get

r=-0.85650

Therefore option D is correct.
