Answer:
Step-by-step explanation:
We are asked to find the length of a segment or the <em>distance</em> between the 2 points. The formula for distance is:
where (x₁ y₁) and (x₂, y₂) are the points. We are given the points ( -5, 4) and (6, -3). If we match the number and the corresponding variable, it is:
- x₁= -5
- y₁= 4
- x₂= 6
- y₂ = -3
Substitute the values into the formula.
Solve inside the parentheses.
- 6--5 (Back to back negative signs become a positive)= 6+5 =11
- -3-4= -7
Solve the exponents.
- (11)²= 11*11= 121
- (-7)²= -7*-7= 49
Add.
Even though it's not specified, we could round to the nearest hundredth to make the answer more concise. The 8 in the thousandth place tells us to round the 3 to a 4 in the hundredth place.
- 13.03<u>8</u>4048104
The length of the segment is <u>√170</u> or approximately <u>13.04. </u>
Answer:
Length = 8 inch , Width = , This equation models the situation
Step-by-step explanation:
Given as ;
The Area of Rectangle is 12 inches²
The Length of Rectangle is 5 inches longer than twice the width
Let The Length = L inches
The Width = W inches
According to question ,
L = 5 + (2 × w )
∵ The Area of Rectangle = Length × width
Or, 12 inches² = [ 5 + (2 × w ) ] × w
Or, 12 inches² = 5 w +2 w²
Or, 2 w² + 5 w - 12 = 0
Or, 2 w² + 8 w -3 w - 12 = 0
Or, 2 w (w +4) - 3 (w + 4) = 0
I.e (w + 4) ( 2 w - 3) = 0
So , w = -4 , and w =
∴ Length = 5 + (2 × w ) =
Length = 5 + (2 × )
so , L = 5 + 3 = 8
Hence Length = 8 inch , Width = This equation models the situation Answer
