Answer:
diameter = 2.5 feet
Step-by-step explanation:
Circumference of a circle is given as C = πd
Circumference of the tree trunk = 7.85 ft
π = 3.14
Diameter of the tree trunk = d
Thus:
7.85 = 3.14*d
Divide both sides by 3.14
7.85/3.14 = 3.14*d/3.14
2.5 = d
d = 2.5 ft
Answer:
The x-intercept is 2/3 and the y-intercept is -1/3
Step-by-step explanation:
In order to find this, we need to note that the x-intercept is the value of x, when y = 0. So we plug in y = 0 and see what the x value is.
3x - 6y = 2
3x - 6(0) = 2
3x = 2
x = 2/3
The y-intercept is the opposite. It is the y value when x = 0. So we do the same with the other term.
3x - 6y = 2
3(0) - 6y = 2
-6y = 2
y = -2/6
y = -1/3
You can start with the form
∆y(x -x1) -∆x(y -y1) = 0
Here, we have
∆y = 11-(-3) = 14
∆x = -3-1 = -4
and we can choose (x1, y1) = (1, -3). This gives
14(x -1) -(-4)(y -(-3)) = 0
14x +4y -2 = 0
All these terms have a common factor of 2 that we can remove. Adding 1 to the result puts it in standard form:
7x +2y = 1
Answer: 9
Explanation: you would use PEMDAS to solve the algebraic expression first by doing parentheses so subtract 8 and 7 which leaves you with 4 + 1 times 6-1. You would then multiply 1 into 6 which would leave you with 4 + 6 - 1 which you would then sum up 4 and 6 which leaves you with 10-1 which would give you the answer of 9
So the answer would be 9
Hope this helps!
Answer:
x = {-2, 2/3}
Step-by-step explanation:
2x = -4
x = -2
3x = 2
x = 2/3
x = {-2, 2/3}
