y = - 2x + 7; slope m = -2
Parallel lines, slope is the same
So y = -2x + b
b = y + 2x
Passing thru (4 , 1)
Plug in
b = 1 + 2(4)
b = 9
Equation
y = - 2x + 9
Find the volume of the bottom and top separately and then add them. Cylinder volume is the area of the bottom times the height (22/7)(5^2)•175=13750 ft^3
The volume of a sphere isV=(4/3)(22/7)r^3where r is the radius. also 5 since it fits on the cylinder. Also we only want half the sphere so useV=(2/3)(22/7)•5^3=261.9 ft^3 round upto 262. Now add together 13750+262=14,012 ft^3
Hope this helps~!!!!!
Answer:
la respuesta que buscas es bastante simple pero no lo sé
Step-by-step explanation:
A^2-8a-48=0
factor
(a+4)(a-12)=0
set each equal to 0
a+4=0 a-12=0
a=-4,12
I encourage you to draw in the diagonal. The diagonal of a square will create a triangle with the sides of the square. Specifically, this is a right triangle as the angles of a square are right angles by definition.
Use the Pythagorean theorem: a^2 + b^2 = c^2. In this case, sides a and b are each 7sqrt(3), and c is the diagonal of the square.
a^2 + b^2 = c^2
(7sqrt3)^2 + (7sqrt3)^2 = c^2
294 = c^2
c = sqrt(294) = 7sqrt(6)
