Answer:
i think its A
Step-by-step explanation:
divide both sides by -2 which makes the y int -3 and A has a negative slope
Answer: the diameter of the circle is 226 cm
Step-by-step explanation:
The formula for determining the length of an arc is expressed as
Length of arc = θ/360 × 2πr
Where
θ represents the central angle.
r represents the radius of the circle.
π is a constant whose value is 3.14
From the information given,
Length of arc = 88π
θ = 140 degrees
Therefore,
88π = 140/360 × 2 × π × r
88π = 140/360 × 2 × π × r
Dividing both sides of the equation by π, it becomes
88 = 140/360 × 2r
88 × 360 = 140 × 2r = 280r
280r = 31680
r = 31680/280
r = 113 cm
Diameter = radius × 2
Diameter = 113 × 2 = 226 cm
The equation, in point-slope form of the line that is parallel to the given line and passes through the point (-1, -1) is y + 1 = 3(x + 1).
<u>Solution:</u>
Given that, a line passes through (0, -3) and (2, 3).
We have to find the line equation which is parallel to above line and passes through (-1, -1).
Now, let us find the slope of the given line.
So, slope of given line is 3,
Then, slope of required line is also 3, as slopes of parallel lines are equal.
Then, required line equation in point – slope form is given as:
Hence, the line equation is y + 1 = 3(x + 1).
Given length of the long board = 18 feet
Mr. Sheffo wants to make shelf with boards that are = feet or feet
So, the number of pieces he can cut from the long board are =
= = = boards
As the number can be a whole number, so 14 boards is the answer.
