3 (7 + 4)² - 14 ÷ 7
3 (11)² - 14 ÷ 7
3 (121) - 14 ÷ 7
363 - 14 ÷ 7
363 - 2
361
Answer with explanation:
The equation of any line with slope 'm' and passing through any point 
is given by
As we know that the general equation of a line with slope 'm' is 
Comparing with the given equation 
we can conclude slope of the given line is 
Now we know that the product of slopes of perpendicular lines is -1
Mathematically we can write for perpendicular lines
Thus the slope of the required line is obtained from the above relation since it is given that they are perpendicular
Hence using the given and the obtained values the equation of the required line is
Part b)
The angle of intersection between 2 lines with slopes 
is given by
Comparing the equations of given lines
with the standard equation we get
Thus the angle of intersection becomes
it should be 8
to find median you line up the numbers in order and divide by 2
Answer:
- When Three sides of the triangle are known
- Two sides of the triangle is known and corresponding angle is included
- Two angles known and their included side given
- Two angles known and the length of a non included side is given
Step-by-step explanation:
The measure that will determine a unique triangle are
- when Three sides of the triangle are known
- Two sides of the triangle is known and their corresponding angle is included
- Two angles known and their included side given
- Two angles known and the length of a non included side is given
unique triangles are termed unique because they can be drawn only using one way
<span>For the Oliver Company to break even, the total revenue must equal the sum of the variable costs and the fixed cost. Mathematically, this can be represented as:
Total revenue = 0.4*(Total revenue) + (Fixed Costs)
Let the number of units sold be x. then,
7*x = 0.4*(7*x) + 6300
Thus, x = 6300/(0.6*7) = 1500 units.
Thus the company will have to sell 1500 units to break even.</span>
