Answer:
- 23
Step-by-step explanation:
We could do this the long way and expand the whole product or note that the terms arise from the product of the a³ and a terms and the product of the a² and a² terms, that is
4a³ × 3a = 12
+ 5a² × - 7a² = - 35
Summing gives
12 - 35
= - 23
with coefficient - 23
Answer:
Step-by-step explanation:
Given: On Monday, the closing value of a share of stock in Company ABC, was . On Tuesday, it closed at
, and on Wednesday, it closed at
. On Thursday, the change in stock value was
. And, on Friday, Company ABC's stock gained
points.
To Find: One shareholder owns shares of Company ABC's stock. What was the total value of their stock in this company at the close of Tuesday.
Solution:
Closing value of Shares of company ABC on Monday
Closing value of Shares of company ABC on Tuesday
Closing value of Shares of company ABC on Wednesday
on Thursday change in stock value was
Closing value of Shares of company ABC on Thursday
on Friday comapny's stock gained points
Closing value of Shares of company ABC on Friday
As one shareholder owns shares of company
Total value of shares on Tuesday is
Hence total value of shareholder's share on close of Tuesday is
Answer:
Step-by-step explanation:
step 1
Determine the slope of the dashed line
The formula to calculate the slope between two points is equal to
we have
(-3,1) and (0,3)
substitute
step 2
Find the equation of the dashed line in slope intercept form
we have
---> given problem
substitute
step 3
Find the equation of the inequality
we know that
Is a dashed line and everything to the left of the line is shaded
so
see the attached figure to better understand the problem
<u>The given options are:</u>
(A)the central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.
(B)the central angle measure of the sector divided by the total angle measure of a circle multiplied by the circumference of the circle will yield the area of the sector.
(C)the central angle measure of the sector multiplied by the area of the circle will yield the area of the sector.
(D)the central angle measure of the sector multiplied by the circumference of the circle will yield the area of the sector.
Answer:
(A)the central angle measure of the sector divided by the total angle measure of a circle multiplied by the area of the circle will yield the area of the sector.
Step-by-step explanation:
The area of the shaded sector can be determined using the formula:
Therefore, the formula is:
Therefore, the formula is best explained by Option A.
