A parallelogram is formed by the supports that attach a basketball backboard and rim to the wall. The angles change as the baske

irina [24]

The measure of angle BCD is 32 degrees

<h3>How to determine the value of BCD?</h3>

The image of the parallelogram that completes the question is added as an attachment.

The given parameter is:

m<DAB = 32 degrees

From the attached image, we can see that BCD and DAB are opposite angles.

Opposite angles of a parallelogram are equal.

So, we have:

BCD = 32 degrees

Hence, the measure of BCD is 32 degrees

The common ratio of a geometric series is 1/4 and the sum of the first 4 terms is 170.

Illusion [34]

Answer: the first term of the series is 128

Step-by-step explanation:

In a geometric sequence, the consecutive terms differ by a common ratio. The formula for determining the sum of n terms, Sn of a geometric sequence is expressed as

Sn = a(1 - r^n)/(1 - r)

Where

n represents the number of term in the sequence.

a represents the first term in the sequence.

r represents the common ratio.

From the information given,

r = 1/4 = 0.25

n = 4

S4 = 170

Therefore, the expression for the sum of the 4 terms, S4 is

170 = a(1 - 0.25^4)/(1 - 0.25)

170 = a(1 - 0.00390625)/(1 - 0.25)

170 = a(0.99609375)/(0.75)

170 = 1.328125a

a = 170/1.328125

a = 128

Given that the measurement is in centimeters, find the area of the circle to the nearest tenth. (Use 3.14 for π)

kvv77 [185]

Answer:

Option D) 254.3 cm2

Step-by-step explanation:

we know that

The area of a circle is equal to

$A=\pi r^{2}$

we have

$r=9\ cm$

substitute

$A=(3.14)(9)^{2}=254.3\ cm^2$
