Step-by-step explanation:
2x-y=4 means y=2x-4. -> slope of the parallel line is 2.
so using pt slope form,
y+11=2(x+3)
y+11=2x+6
y=2x-5
Answer:
Given the total area of the U.S. = 3.79 million square miles
The area of Alaska = 0.67 million square miles
Step-by-step explanation:
We have given the area of the United States and the area of Alaska. Since Alaska is a part of the United States so the area of Alaska is already included in the given area of the U.S.
Thus to find the probability that the meteor will hit Alaska can be calculated by dividing the area of Alaska from the area of the U.S.
The probability to hit the Alaska = 0.67 / 3.79
The probability to hit the Alaska = 0.1767
Formula for circumference of circle:
C=2πr
here radius, r=4 cm and π=3.142
Put values in formula.
C=2(3.142)(4)
C=25.1 cm (Rounded to 1 decimal place)
Answer: Circumference of the circle is 25.1 cm (Rounded to 1 decimal place)
Answer:
48 degrees
Step-by-step explanation:
First, calculate the supplementary angles for 99 degrees and 129 degrees. You would get 81 degrees and 51 degrees respectively.
Then add those two numbers and you'll get 132 degrees. Since a triangle equals 180 degrees, use: x + 132 = 180. You would get x as 48.
Answer:
Step-by-step explanation:
is g(x) equal to 2x²-1, or 2x²+1 ?
f(x) = x²-3
g(x) = 2x²-1
g(f(x)) = g(x²-3) = 2(x²-3)²-1 =2(x⁴-6x²+9)-1 =
2x⁴-12x²+17
