What is the explicit formula for the sequence. -8. ,-3,2, a. an=12+(n-1)5. b. an=-8+(n-1)5. c. an=-8+(n-) d. an=5+(n-)

B) an=-8+(n-1)5

Step-by-step explanation: The explicit formula for a sequence, will be the one that corresponds to the numbers of the sequence. From the given options, the one that represents the given sequence, is the corresponding to option B, we can verify that by calculating the first terms and comparing them to the given ones:

an=-8+(n-1)5

a1=-8+(1-1)5=-8+(0)5=-8

a2=-8+(2-1)5=-8+(1)5=-3

a3=-8+(3-1)5=-8+(2)5=2

a4=-8+(4-1)5=-8+(3)5=7

as we can see, all the numbers match with the given sequence.

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
