Answer:
1.024x10^17
Step-by-step explanation:
5^5(16^2x5^3)^3
find the 5^5
3125(16^2x5^3)^3
distribute the power of 3 into the parentheses
3125(16^6x5^9)
multiply
3125(16777216x1953125)
1.024x10^17
The vertex form of a quadratic function is:
f(x) = a(x - h)² + k
The coordinate (h, k) represents a parabola's vertex.
In order to convert a quadratic function in standard form to the vertex form, we can complete the square.
y = 2x² - 5x + 13
Move the constant, 13, to the other side of the equation by subtracting it from both sides of the equation.
y - 13 = 2x² - 5x
Factor out 2 on the right side of the equation.
y - 13 = 2(x² - 2.5x)
Add (b/2)² to both sides of the equation, but remember that since we factored 2 out on the right side of the equation we have to multiply (b/2)² by 2 again on the left side.
y - 13 + 2(2.5/2)² = 2(x² - 2.5x + (2.5/2)²)
y - 13 + 3.125 = 2(x² - 2.5x + 1.5625)
Add the constants on the left and factor the expression on the right to a perfect square.
y - 9.875 = 2(x - 1.25)²
Now, we need y to be by itself again so add 9.875 back to both sides of the equation to move it back to the right side.
y = 2(x - 1.25)² + 9.875
Vertex: (1.25, 9.875)
Solution: y = 2(x - 1.25)² + 9.875
Or if you prefer fractions
y = 2(x - 5/4)² + 79/8
The correct option is B. Reread the directions for each section.
If you have time left after completing the test don't reread the directions for each section.
<h3>What is meant
previewing a test?</h3>
In order to find the various problem kinds and their point values during the test preview, you must read the complete test. Mark the questions that you can answer quickly and easily.
The benefits of previewing the test are-
- You will probably be given credit for the answers even if you accidentally copied them from the scratch paper.
- Your effort on the scratch paper can earn you some points if a thoughtless mistake causes you to get the answer wrong.
- If you do make a mistake, it will be simpler to find it when the instructor goes through the test.
- By doing this, you can avoid making the same errors on your next exam.
Therefore, resolve each issue by re-entering the solution into the equation or performing the opposing operation needed to provide the appropriate response. Do not leave the testing room until the bell has rung or after you have gone over each problem twice.

Number of loaves Number of Bananas
1 2 1/2
2 5
4 10
Step-by-step explanation:
My friend helped me with this and since I saw no answer here I wanted to help YOU!!!!
So the first one was easy because it already said it in the number line.
The second one you simply multiply 2x 2 1/2
The third one you multiply 4x 2 1/2.
Hope it helps! Stay safe and dont go out during Quarantine!!!!!!!!!!
Answer:
Part A
20x + 25y = 210 --> D.
Part B
If jane purchased exactly 4 shirts she must have purchased Exactly ___ skirts. (round to the nearest tenth)
20*4 + 25y = 210 --> y = 5.2
is it possible for jane to purchase exactly 4 shirts? ____(yes or no)
no, because she can't buy 5.2 skirts.
