What is the slope of the line through (-7.-2) and (-6,7)
2 answers:
Answer:
Step-by-step explanation:
The slope formula is:
where (x₁, y₁) and (x₂, y₂) are the points the line passes through.
The points given are: (-7,-2) and (-6,7). Therefore,
Substitute the values into the formula.
Solve the numerator by adding 7 and 2.
Solve the numerator by adding 7 to -6.
Divide 9 by 1.
The slope of the line is 9.

P(inside larger square and outside smaller) =
Step-by-step explanation:
Probability is the result of the division of the number of possible outcome by the number of an event.
In the question, for a point chosen, the point can be in the small square only or in the area or region between the small square and the big square as such,
Area of larger square = area of region between both squares + area of smaller square
Where the area of a square is S × S where S is the side of a square
Area of larger square = 10 × 10
= 100 cm square
Area of smaller square = 7 × 7
= 49 cm square
Area of the region between both squares
= 100 - 49
= 51 cm square
The probability that a dot selected is inside the larger square and outside the smaller is
P(inside larger square and outside smaller) = Area of region between both square/ Area of larger square
P(inside larger square and outside smaller) =
Answer:
31.4 in
Step-by-step explanation:
the formula for circumference is 2**radius. Since the diameter (which is the radius multiplied by 2) is labeled we can divide 10 by 2 to get the radius. 10/2 is 5. Since pi is an infinite number, we round it to 3.14. Then, plug in the numbers. The expression will be 2*3.14*5. 2* = 10 and 10 * 3.14 you can just move the decimal so the answer is 31.4.
