To find this, use the distance formula. D= square root over... (x2-x1)^2+ (y2-y1)^2. Now plug in your coordinates.
D= square root... (4- -7)^2+ (-5-3)^2. Simplify. 4- -7=11 (two neg= positive) -5 -3= -8. So,
D= square root... 11^2+ -8^2. Simplify. 11^2= 121. And -8^2=64. Now just take the square root after adding. 121+64= 185. And the square root of 185 isn’t a whole number, so your final answer is D= (square root over) 185. Hope this helps
Answer:
The volume of solids is measured in cubic measurements.
Step-by-step explanation:
Examples:
Volume of a cube: V = a^3
Volume of a sphere: 4/3 x pi x r^3
Volume of a triangle: 1/2 x b x h x l
For instance, a sphere with the radius of 5 feet:
4/3 x pi x 5^3 = V
V = 523.6 cubic feet
<span>The system of linear equations
−x − y = 1
y = x + 3
can be solved in various ways. This problem hints that you should graph both lines and find the coordinates of their point of intersection.
But we can also solve this system using substitution. Note that y = x + 3. We can subst. x + 3 for y in the 1st equation, as follows:
-x - (x+3) = 1. This simplifies to -x -x - 3 = 1, or -2x = 4, or x = -2.
Since y = x + 3, subbing -2 for x produces y: y = -2 + 3 = 1
Thus, the solution is (-2, 1). </span>
