Yo get a perpendicular line you have to have the reciprocal of the slope, in this case the slope is -2/5 so the reciprocal is 5/2. You then plug the coordinates in for y and x with the slope you found to find b (or the y-intercept). The equation will be 2=-6(5/2)+b. Solve and b=17. The final equation is y=(5/2)x+17
Answer:
139.5 mm
Step-by-step explanation:
The area of a geometric shape with all sides of equal length is:
A (1/2)nsr
n = the number of sides
s = the length of the sides
r = the length of the apothem
The apothem is the line going from the center point of the shape to the middle of one of the sides.
A = (1/2)(5)(9)(6.2)
A = (1/2)279
A = 139.5 mm
We are given the diameter of the circle, I assume. In this case, the formula of the area of the circle is expressed as A = pi d^2/4. where pi is a constant. The only option taht makes sense here is C. 6.25 in2. This should have the constant pi on it.
Answer:
8u =32 this is the equation
Answer:
-61.83
Step-by-step explanation:
Given expression is ![\frac{7}{-2.5+8.5} +\frac{0.6\times(8+13)}{-0.2}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B-2.5%2B8.5%7D%20%2B%5Cfrac%7B0.6%5Ctimes%288%2B13%29%7D%7B-0.2%7D)
We know that 0.6 is 3 times 0.2 so we can cancel 0.6
Also 8.5-2.5 = 6
⇒![\frac{7}{6}-\frac{3\times21}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B6%7D-%5Cfrac%7B3%5Ctimes21%7D%7B1%7D)
⇒
= -61.83
