Which polynomials are in standard form?
2 answers:
Answer:
A. x^2 + 3x + 2
D. 3x^4 + 4x^3 - 3x^2 - 1
E. 3t^3 + 3t^2 + 2t
Step-by-step explanation:
Standard form is where the equation is set up so that the exponents decrease from left to right, and where you put a number with no variable or exponent last.
Answer:
option A, D and E
Step-by-step explanation:
The polynomial is in standard form only when the exponents starts with largest exponent and keeps on decreasing from greatest to least
has largest exponent 2 and then x
option B and C has exponents that are not in order.
has largest exponent 4 and the exponents are from greatest to least.
has largest exponent 4 and the exponents are from greatest to least.
last option has exponents that are not in order.

Answer:
The length of the circular arc is 8.64 inches
Step-by-step explanation:
Length of circular arc (L) = central angle/360° × 2πr
central angle = pie/4 = 45°, r (radius) = 11 inches
L = 45°/360° × 2 × 3.142 × 11 = 8.64 inches (to two decimal places)

Answer:
Step-by-step explanation:
The cross section of a sphere is a circle with area , where radius is given as 4 The cross section of the cube is a square with area , where a is side length of square
The circle area = the square area . Thus we have:
Answer:
area = 277 units²
Step-by-step explanation:
area = (25 x 5) + (8 x 13) + (8 x 6) = 277 units²
