Answer:
1:5 or you can write 1/5 or 1 to 5
Step-by-step explanation:
F(x) = x • 3 • 2 + 47x - 60
fx =3x - 24x + 47x - 60
fx = 26x - 60
x = - 60/f - 26
The correct answer is (A) 45 minutes.
Explanation:
This question is bit tricky because the graph is adjusted in such a way in the grid that it is bit hard to find the slope of it (although it is a straight line). Also we do not know where the line intersects the y-axis (for y-intercept of the equation y = mx + c). Hence we need to guess it. Let me explain how (in less time)!
As you can see in the graph that at 42 minutes, the value of "point scored" is BELOW 28 (right?). And the graph is increasing (as it is a straight line). Hence "30 points scored" MUST have the value greater than 42 minutes. So in options, the only value that is greater than 42 minutes is 45 minutes (Option A)

Answer:
with these characteristics, place the
semi-ellipse on coordinate axes in a convenient position and draw it.
5. What is the equation of the ellipse? How wide will the canal need to be for the
Petroleum ship?
6. Now that you know which of the two alternatives provides the widest channel, consider other
factors. His department is also in charge of verifying the depth of the channel, the
amount of river traffic and other details. For example, if there was a flood in the river and
the water level will rise 10 feet, how would free space be affected? Take a decision
about which project you think would be best as far as your department is concerned and
ANSWER
C. 145.75 yd²
EXPLANATION
First we need to calculate the area of the four triangular faces.
The lateral surface area
The area of the base is
To find the total surface area, we add the area of the square base to the area of the 4 triangular faces.
Therefore the total surface area is
