Answer:
f(x) = -x^2 - 6x - 10
Step-by-step explanation:
Please write the original equation as f(x) = -(x + 3)2 - 1, as "(x + 3)2 is meaningless. We want:
f(x) = -(x + 3)^2 - 1, where " ^ " denotes exponentiation.
Expanding this, we get:
f(x) = -(x^2 + 6x + 9) - 1, or
f(x) = -x^2 - 6x - 9 - 1, or:
f(x) = -x^2 - 6x - 10 This matches the first answer choice.
Answer:
6.7
Step-by-step explanation:
6.7 because 3.4 is way to small 7.9 would be close but not the right length and 8.5 is way too long to be on the bottom.
Hope this help stay home stay safe.
Have a great day :) :) :) :)
FYI this is probably the easiest question I have ever seen. Just use a calculator. The answer is 9R1
Step-by-step explanation:
First, you need to find the difference 3201-2750=451, it has increased by 451, then divide the difference by the original number, which is 2750 because thats what she started off with (3201 would be the new number)
Increase% = Increase ÷ Original Number ×100
451÷2750×100=16.4%
Given:
Length of the playground: 125 ft
Width of the playground: 60 ft
Depth of the mulch: 6 inches
Convert ft and inches to yards
1 yard = 3 feet
Length: 125ft/3ft = 41.67 yd
Width: 60ft/3ft = 20 yd
1 ft = 12 inches
Depth: 6 inches * 1ft/12inches = 6ft/12 = 1/2 ft
Depth: 0.5 ft * 1yd/3ft = 0.5yd/3 = 0.17 yd
Volume = Length * Width * Depth
V = 41.67yd * 20yd * 0.17yd
V = 141.68 yd³
V = 125ft * 60ft * 0.5ft
V = 3,750 ft³
1 cubic yard = 27 cubic feet
3,750ft³ * 1yd³/27ft³ = 3,750 yd³ / 27 = 138.89 or 139 yd³ LETTER B.
