Answer:C. 2x2 + 3x − 1 is quadratic
Step-by-step explanation:
Quadratic expressions are polynomial expressions in which the highest power of the variable is 2.
Looking at option A, the highest power of the variable in the polynomial is 4. Therefore, it is not a quadratic expression.
Looking at option B, the highest power of the variable in the polynomial is 3. Therefore, it is not a quadratic expression.
Looking at option C, the highest power of the variable in the polynomial is 2. Therefore, it is a quadratic expression.
Looking at option D, the highest power of the variable in the polynomial is 1. Therefore, it is not a quadratic expression.
Answer:
26.74
Step-by-step explanation:
sinA = .45
A=sin^-1 (.45)
A=26.74368
Hundredth equals to the 2nd number after the decimal point, which is "4".
FYI, Tenths is the first after the point, thousandths is the third and so on....
So round it off, the "3" is smaller than 5 which makes the rounded number the same. So 26.74 still remains 4.
If it is 26.745, then the value will be 26.75 as the thousandths place is bigger equals to "5" , adding a one to the rounded off number
Hope this isn't too confusing to. be said in wordss

Answer:
The playground covers of a square mile
Step-by-step explanation:
The playground is a rectangular ground. The area of a rectangle is given by legth * width, hence,
The area of the playground is length * width
Area = sq. mi
Hence the playground cover of a square mile
