There are 100 students at a college who have taken a course in calculus, 110 who have taken a course in discrete mathematics, an

vesna_86 [32]

Answer:

110 students

Step-by-step explanation:

The number of students who have only taken calculus is given by the number of students who have taken calculus minus the students who have taken both classes:

$C =100 -50\\C= 50\ students$

The number of students who have only taken discrete mathematics given by the number of students who have taken discrete mathematics minus the students who have taken both classes:

$D =110 -50\\C= 60\ students$

The number of students that have taken a course in either calculus or discrete mathematics is:

$E = C+D = 50+60\\E= 110\ students$

tino4ka555 [31]

Answer:

The set of coefficients asociated with the given polynomial in ascending order is $[C] = \{4,0,5\sqrt{3}\}$ .

Step-by-step explanation:

Let $y = 5\sqrt{3}\cdot x^{2}+4$ , which is a polynomic function, defined as:

$y = \Sigma_{i=0}^{n}c_{i}\cdot x^{i}$ (1)

Where:

$c_{i}$ - i-th Coefficient.

$x^{i}$ - i-th Power.

$n$ - Grade of the polynomial.

We notice that given polynomial has degree 2 and can be rewritten by applying this definition:

$y = 4 + 0\cdot x + 5\sqrt{3}\cdot x^{2}$

Then, the set of coefficients asociated with the given polynomial in ascending order is:

$[C] = \{4,0,5\sqrt{3}\}$

If f(1) = 7 and f(n) = 5f (n − 1) then find the value of f(5).

nevsk [136]

Answer:

f(5) = 4375

Step-by-step explanation:

Given f(n) = 5f(n - 1) and f(1) = 7

This allows us to find the next term in the sequence from the previous term

f(2) = 5f(1) = 5 × 7 = 35

f(3) = 5f(2) = 5 × 35 = 175

f(4) = 5f(3) = 5 × 175 = 875

f(5) = 5f(4) = 5 × 875 = 4375

The product of n and 6 divided by 4 in algebraic expression

Damm [24]

Answer:

$6n \div 4$

Step-by-step explanation:

n is a variable and multiplied by 6, so it is attached to 6. (6 is known as the coefficient.) Then it is divided by 4. (4 is known as the constant because there is no variable attached to it.)

$6n \div 4$
