Answer:13
Step-by-step explanation: Each classmate should get 13 marbles. To solve this simply divide 455 by 35.
Step-by-step explanation:
A term is a number, a variable, or a constant multiplied by a variable or variables.
Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different.
A coefficient is a multiplicative factor in some term of a polynomial (expression).
Constant is a term in the algebraic expression that contain only number.
n + 5n = n + 5n + 0
terms: n, 5n
like terms: n, 5n
coefficients: 1, 5
constant: 0
simplified form: n + 5n = 6n
term: 6n
coefficient: 6
constant: 0
=======================
12c - c = 12c - c + 0
terms: 12c, -c
like terms: 12c, -c
coefficients: 12, -1
constant: 0
simplified form: 12c - c = 11c
term: 11c
coefficient: 11
constant: 0
========================
-4j - 1 - 4j + 6
terms: -4j, -1, -4j, 6
like terms: -4j, -4j and -1, 6
coefficients: -4, -4
constants: -1, 6
simplified form: -4j - 1 - 4j + 6 = (-4j - 4j) + (-1 + 6) = -8j + 5
term: -8j, 5
coefficient: -8
constant: 5
Using integration, it is found that the area between the two curves is of 22 square units.
<h3>What is the area between two curves?</h3>
The area between two curves y = f(x) and y = g(x), in the interval from x = a to x = b, is given by:

In this problem, we have that:
.
Hence, the area is:


Applying the Fundamental Theorem of Calculus:


The area between the two curves is of 22 square units.

<h3>
Answer: 19.1</h3>
====================================================
Work Shown:
tan(angle) = opposite/adjacent
tan(C) = AB/BC
tan(theta) = x/BC
tan(23) = (8.1)/BC
BC*tan(23) = 8.1
BC = (8.1)/tan(23)
BC = 19.0824041631723
BC = 19.1
In this case, rounding to 3 sig figs means we round to the nearest tenth.
Make sure your calculator is in degree mode.
