Step-by-step explanation:
In scientific notation, we represent numbers as a product of a decimal number between 1 and 10, multiplied by a power of 10. This allows us to express very large or very small numbers in a compact and standardized format.
To express 5,806 in scientific notation, we need to move the decimal point to the left so that the number becomes a value between 1 and 10. The number of places we move the decimal point determines the power of 10.
Here's how we can do it step by step:
1. Start with the given number, 5,806.
2. Move the decimal point to the left until the number becomes a value between 1 and 10. In this case, we need to move the decimal point three places to the left.
- 5,806.0 -> 580.60 -> 58.06 -> 5.806
3. Count the number of places you moved the decimal point. In this case, we moved it three places to the left.
4. Write the number as a product of the decimal number and 10 raised to the power of the number of places you moved the decimal point.
- 5.806 x 10^3
Therefore, 5,806 in scientific notation is 5.806 x 10^3.
Remember, scientific notation is a useful way to represent large or small numbers and make them easier to work with in calculations and comparisons.
sorry i got it wrong i just learned this so i dont know i though AI was right
B=(xy + x)(xy + x)
C=(2x – 3)(–3 + 2x)
D=(16 – x2)(x2 – 16)
E=(4y2 + 25)(25 + 4y2)
The correct answers are:
B=(xy + x)(xy + x) ; C=(2x – 3)(–3 + 2x) ; and E=(4y² + 25)(25 + 4y²)
Explanation:
In order to have a perfect square trinomial, we must multiply two binomials that are exactly the same. For (xy+x)(xy+x), are multiplying two identical binomials.
For (2x-3)(-3+2x), we are multiplying two binomials that are the same but written in a different order. The same is true of (4y² + 25)(25 + 4y²).
Answer:
A and E and C
Step-by-step explanation:
A perfect square trinomial can be written as the square of a binomial.
Answer:
the answer is C
Step-by-step explanation:
19.65 + 2.35 is exactly 22, not including tax
Answer:
A and C
Step-by-step explanation:
A. 15% off $25
15% = 0.15
0.15 x 25 = 3.75
25 - 3.75 = 21.25
22 or under? Yes
B. 30% off $32
30% = 0.30
0.30 x 32 = 9.60
32 - 9.60 = 22.40
22 or under? No
C. $19.65 plus a 2.35 shipping fee
19.65 + 2.35 = 22
22 or under? Yes
D. $20.45 plus a $1.60 shipping fee
20.45 + 1.60 = 22.05
22 or under? No
Even though this is late, the other answer did not mention A being the answer as well so I hope this helped!
Answer:
This formula is related to Pythagorus theorem which states that in a right angled triangle square of hypotenuse is equal to sum of the squares of other two sides.
In other words, C²=B²+A²
Perimeter is the sum of the length of the sides used to make the given figure. The distance that Fiona will jog is 760 yards.
Perimeter is the sum of the length of the sides used to make the given figure.
Given that the block is rectangular, and it is 180 yards long and 200 feet wide. Now, given that Fiona is going to Jog once around the block, therefore, the distance that Fiona will cover is the perimeter of the block.
Thus, the perimeter of the block is,
The perimeter of the block = 2(Length + Width)
= 2(180 yards + 200 yards)
= 2(180 yards + 200 yards)
= 2(380 yards)
= 760 yards
Hence, the distance that Fiona will jog is 760 yards.
