X to the 8/15 power. When you have a power raised to another power, you multiply the exponents.
Answer:
The area of the triangle is 16 unit²
Step-by-step explanation:
Area of a triangle given coordinates
D = (-1, -2)
E = (-5, 2)
F = (2, 2)
We note that the formula for finding the are triangle given the coordinates if presented as follows;
A = (x₁·y₂ + x₂·y₃ + x₃·y₁ - x₁·y₃ - x₂·y₁ - x₃·y₂)/2
Where:
D = (x₁, y₁)
F = (x₂, y₂)
E = (x₃, y₃)
Therefore;
x₁ = -1, y₁ = -2, x₂ = 2, y₂ = 2, x₃ = -5, y₃ = 2
Which gives;
A = ((-1)*(-2) + 2*2 + (-5)*(-2) - (-1)*2 - 2*(-2) - (-5)*2)/2
A = ((-1)·(-2) + 2·2 + (-5)·(-2) - (-1)·2 - 2·(-2) - (-5)·2)/2 = 16
The area of the triangle = 16 unit².
Answer:
8
Step-by-step explanation:
Actually since there is only 4 cups of grape juice and 7 cups of lemonade you could only make 4 cups of punch. So your answer would be 8 because 4x2=8
Answer: 11,440 ft change in altitude
Step-by-step explanation: To do this equation, you first need to find a positive number that is high enough to reach positive 11,100. Because we are not starting at zero on the number line and are instead starting at negative 340, the number will be a little higher than 11,100. The simplest way to find the answer is by changing negative 340 to a positive value and adding it to positive 11,100. This should equal 11,440 To prove this, grab a calculator and add 11,440 to negative 340. To make 340 a negative integer, type in that number and then click the button that looks like this, +/_ Once you have added 11,440 to negative 340, the sum of the two integers should pop up as 11,100 on your calculator. The final and correct answer is equivalent to a 11,440-foot change in altitude.
