The answer is v=5x^2-100x+500. First, since we are finding the volume of a square you already know that the equation for a square is volume= length*width*height. Because 5 inches was cut off from each side, that means that each side is now 10 inches shorter than it originally was. So, then you substitute the values into the formula. So the length is x-10 and the width is also x-10 and the height is 5in. Then you write the formula like this (x-10)(x-10)5. Second, you substitute the values into the formula. Since there are 2 x's that would make x^2 and add that to 5 that would make 5x^2. Then you multiply -10*10=-100. Finally, you multiply -10*-10-5=500. Then you add them all together to get 5x^2-100x+500
Since x is the cost of the oranges per pound in cents, the total amount spent on oranges in cents is 3x. Then, you spent 59 cents on cucumbers and 35 cents on bananas. The total amount spent on all food is the sum of the individuals. 3x+59+35. Combine like terms to get 3x+94. This will give you your total in cents. If you need a total in dollars, you would just multiply that expression by 0.01.
We can answer the first part of the question not taking intersecting function into account. The domain of
is all the numbers, x∈(-∞, +∞) and the range is y∈(-∞, 36]. We can observe these results with the help of a graph, as well. Since we are talking about the rainbow, the values above the ground level will make sense. In this case, we will take into account the range as it changes between 0 and 36, included and the domain between -6 and 6. Here (0;36) is the y-intercept and (-6;0) and (6;0) are the x-intercepts of the parabola.
Since in our problem, the linear function that intersects parabola is not given, we have to provide it by ourselves according to the conditions of the problem. It could be any line intersecting parabola in two points. One important point is that the y-intercept has to be no more than 36. Considering these conditions, we can set our linear function to be
. We can observe the points that we included in the table (they have been given with orange dots in the graph and the table is attached below). We can see that the values of the function (values of y) are positive. Indeed, we are discussing the part of the rainbow above the ground level.
The system of equations with linear and quadratic functions has got two solutions and we can observe that result from the graph. The solutions are (-5.823; 2.088) and (5.323; 7.662). The solutions are the intersection points.
Answer:
the answer if the first picture
Step-by-step explanation:
the second one is the explanation
Answer:
1/2
Step-by-step explanation:
2/3 (2/8 + 4/8) =
First simplify what is inside the parentheses
2/8+4/8 = 6/8
Replace with 6/8
2/3 (6/8) =
Then multiply
2*6 =12
3*8 = 24
12/24
Divide top and bottom by 12
1/2
