The problem evaluates the expression 47 + 2d, by substituting d = 3. This results in 47 + 2*3, which simplifies to 47 + 6. The final answer is 53.
This is a simple algebraic problem. The expression you're asked to evaluate is
47 + 2d
and you've been told to substitute
d = 3
. So substituting, we get 47 + 2*(3). The multiplication operation takes precedence according to the order of operations, so next we calculate 2*3 to get 6. Adding this to 47 gives us 53. Therefore, the solution to 47 + 2d, for d = 3, is 53.

Step-by-step explanation:
B. F(x) = 2x^2 + 5x - 3
C. F(x) = -x^3 + 5x2 + 7x - 1
D. F(x) = -x^3 + sq -x
E. F(x) = 3/5x^4 - 18x^3 + x^2 - 10x + 3.5
The function F(x) = 2x² + 5x – 3, F(x) = -x³ + 5x² + 7x – 1, and F(x) = 3/5x⁴ – 18x³ + x² – 10x + 3.5 are polynomial function. Then the correct options are B, C, and E.
A polynomial expression is an algebraic expression with variables and coefficients. Unknown variables are what they're termed. We can use addition, subtraction, and other mathematical operations. However, a variable is not divisible.
The polynomial is given below.
If the exponent of the variable is negative and fraction, then the function is not a polynomial function.
A. F(x) = 3x⁻³ – 19, the exponent of the function is negative 3. Then the function is not a polynomial function.
B. F(x) = 2x² + 5x – 3, the exponent of the function is whole number. Then the function is a polynomial function.
C. F(x) = -x³ + 5x² + 7x – 1, the exponent of the function is whole number. Then the function is a polynomial function.
D. F(x) = -x³ + √(-x), the exponent of the function is 1/2. Then the function is not a polynomial function.
E. F(x) = 3/5x⁴ – 18x³ + x² – 10x + 3.5, the exponent of the function is whole number. Then the function is a polynomial function.
Then the correct options are B, C, and E.

The answer is 6.56
Step-by-step explanation:
11.20 is the total. You multiply that by .15 and get $1.68 for the tip. You multiply $11.20 by .05 for the tax and get $.56. You add them together and get $13.44. You subtract that from $20.00 and get $6.56
The length of a wrestling mat with an area of 1444 square feet could be approximately 38 feet, if assuming the mat to be a square. However, without more specific information, the exact dimensions could vary while maintaining the same area.
Without additional information, we can't determine the exact length of the wrestling mat. However, if we assume the mat is a perfect square, where the length and width are equal, then we can find the side length by taking the square root of the area.
To find the square root, you can use a calculator and input 1444. You'll find that the square root of 1444 is approximately 38 feet. This would be the length of each side if the wrestling mat is a square.
Keep in mind that this is an approximation. The actual wrestling mat could have different dimensions but still have an area of 1444 square feet. For instance, it could be rectangular rather than square.

The value of sinA in the triangle is 0.6. Then the correct option is A.
Trigonometry is the branch of mathematics that set up a relationship between the sides and angle of the right-angle triangles.
In the given triangle base is 8 and the perpendicular is 6 units. To calculate sinA we need hypotenuse and then use the Pythagorean theorem.
H² = P² + B²
H² = 6² + 8²
H² = 36 + 64
H² = 100
H = 10
The angle sinA is the ratio of perpendicular and hypotenuse.
sinA = P / H
sinA = 6 / 10
sinA = 0.6
Hence, the correct answer is option A.
