Answer:
y = 2/7x - 40/7
Step-by-step explanation:
y2 - y1 / x2 - x1
-8 - (-4) / -8 - 6
-4/-14
= 2/7
y = 2/7x + b
-4 = 2/7(6) + b
-4 = 12/7 + b
-40/7
The rule for a 270° counterclockwise rotation is (x, y) ---> (y, -x).
So if you rotated (-5,5) 270° counterclockwise around the origin the new coordinates would be (-5,-5).
Hope this Helps!!
Answer:
D
Step-by-step explanation:
6.8 = (6/5)^x
6.8 = 1.2^x
x ln 1.2 = ln 6.8
x = ln 6.8 / ln 1.2
= 10.513966
Answer:
Step-by-step explanation:Let's solve your equation step-by-step.
(4564644)(4434688)=124x2
Step 1: Simplify both sides of the equation.
20242771971072=124x2
Step 2: Subtract 124x^2 from both sides.
20242771971072−124x2=124x2−124x2
−124x2+20242771971072=0
Step 3: Subtract 20242771971072 from both sides.
−124x2+20242771971072−20242771971072=0−20242771971072
−124x2=−20242771971072
Step 4: Divide both sides by -124.
−124x2
−124
=
−20242771971072
−124

Answer:
57
Step-by-step explanation:
The volume of a cone is given by the formula ...
V = (1/3)πr²h
For a pile with a radius of 8.5 m and a height of 9 m, the volume is ...
V = (1/3)π(8.5 m)²(9 m) = 216.75π m³ ≈ 680.94 m³
Then the number of truckloads required to create that size pile will be ...
(680.94 m³)/(12 m³/truck) = 56.745 trucks
Even a partial truck load entails another trip, so ...
57 truck loads of sand are needed.
