Oksi-84 [34.3K]3 years ago

Answer:

x= 4

m<ABC= 56

Step-by-step explanation:

since BD bisects, both sides of the angle are equal.

So we can set up an equation like this: <ABD=<CBD

(9x-8)=(5x+8) calculate for x

you'll find x=4

then put four into one of the angle equations

9(4)-8=28

now we know each side of the angle is 28, double it to find the whole (<ABC)

28+28=56

Blababa [14]
Well 9 3/4 is 9.75 and 27 1/2 is 27.5 so if we take 27.5 and subtract 9.75 you get 17.75 and then all you have to do is 17.75/2 which is 8.875 so the answer would be 8.875 inches on either side

The means and mean absolute deviations of the individual times of members on two 4 times 400 meter relay track teams are shown i
Yakvenalex [24]

The correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.

<h3>What is mean?</h3>

Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data.

The difference between the mean times is about 16 times the mean absolute deviation of the data set.

59.32 - 59.1 = 0.22

2.4 - 1.5 = 0.9

0.22 / 0.9 = 0.25

Therefore the correct answer is option C which is the ratio of the difference in the means of the two teams to the mean absolute deviation of Team B will be 0.25.

Determine the equation of the following polyromial that passes through point (0,6).
Ostrovityanka [42]

Answer:

Cubic polynomial has zeros at x=−1x=−1 and 22, is tangent to x−x−axis at x=−1x=−1, and passes through the point (0,−6)(0,−6).

So cubic polynomial has double zero at x=−1x=−1, and single zero at x=2x=2

f(x)=a(x+1)2(x−2)f(x)=a(x+1)2(x−2)

f(0)=−6f(0)=−6

a(1)(−2)=−6a(1)(−2)=−6

a=3a=3

f(x)=3(x+1)2(x−2)f(x)=3(x+1)2(x−2)

f(x)=3x3−9x−6
