Answer:

390

Step-by-step explanation:

The formula of sum of arithmetic sequence is $\frac{n}{2} (a+Tn)$

The number of this series are 2, 4, 6, 8, 10, 12, . . . . , 60.

The first term ( a ) = 2

The 30th even number is 60

The Tn is the term of the sequence

So the equation is

30/2 x ( 2 + $T_{30}$ )

$T_{30}$ = 60

30/2 x ( 2 + 60 )

30/2 x (62)

1860/2

If f(x) = 4x + 3x2 + 1, then what is the remainder when f(x) is divided by X -2?

Bezzdna [24]

Answer:

remainder = 21

Step-by-step explanation:

If f(x) is divided by (x - h) then the remainder is f(h)

Here f(x) is divided by (x - 2) with h = 2 , then remainder is

f(2) = 4(2) + 3(2)² + 1 = 8 + 3(4) + 1 = 8 + 12 + 1 = 21

Find the circumference of a circle with radius, r = 11.5m. Give your answer in terms of π .

nignag [31]

Answer:

So,

if C = 2πR

you take 2π you get 6.28

so C=6.28 x r

the radius is 11.5 so

6.28 x 11.5 = 72.2566

the circumference is 72.2566

The student-to-faculty ratio at a small collage is 17:3. The total number of students and faculty is 740. How many faculty membe

kozerog [31]

There are 111 faculty members at the college and 629 students at the college.

Step-by-step explanation:

Given,

The student to faculty ratio = 17:3

Total number of 740.

Let,

x be the original number.

Number of students = 17x

Number of faculty = 3x

Number of students + Number of faculty = 740

$17x+3x=740\\20x=740$

Dividing both sides by 20

$\frac{20x}{20}=\frac{740}{20}\\x=37$

Number of students = 17x = 17*37 = 629

Number of faculty = 3x = 3*37 = 111

There are 111 faculty members at the college and 629 students at the college.
