Answer:
648 sq meters is correct.
Step-by-step explanation:
Multiply the two diagonals (18 + 18 = 36)(15 +21 = 36), then divide by 2
(36)(36)/2 = 1296/2 = 648
Answer:
it shows you where they are
Step-by-step explanation:
So here is how we are going to solve this:
The power of the given expression is 3 and the root is 5. So in writing a fractional exponent, we just have to make 3 as the numerator. So multiply both sides by 3/5 to take the root sign off and the final answer would be x^3/5. 3/5 is the power. Hope this answer helps.
Answer:
The answer to your question is y = 4 - 1.5x
Step-by-step explanation:
Data
River's speed = 2 mi/h
David's speed = 6 mi/h
Rate of change = 1.5 mi/h
From the data given, we can conclude that the rate of the boat will be the difference between David's speed and the speed of the boat = 4mi/h.
The slope must be negative because it decreases.
The only equation that satisfies both conditions is the second option.
Answer: choice A) -4
-----------------------------------------------
Step 1) Draw a vertical line through 1 on the x axis
Step 2) Mark the point where the vertical line and the blue curve intersect (or cross each other)
Step 3) Draw a horizontal line through the point marked in step 2. Note how this horizontal line goes through -4 on the y axis.
So the point (1,-4) is on the blue curve. This means if x = 1 is the input then y = -4 is the output. Recall that y = f(x). So f(x) = -4 is the output as well when the input is x = 1.
In short, this is why f(1) = -4
