Answer:

f(-1) = -2

f(0) = 0

f(4) = 8

Step-by-step explanation:

f(x) = 2x

f(-1) = 2(-1)

=> -2

f(0) = 2(0)

=> 0

f(4) = 2(4)

=> 8

Andru [333]
Well the question doesnt show any number for a side or anything but we can solve this with algebra if we say that a side from one base to next has a length of x. so we know each side has length x and that the shape they make is square. This means we are only searching for the diagonal of a square.

remember that a diagonal forms and isoscoles right triangle with the 2 sides being equal and the diagonal as the hypotenuse. Using the pythagoream theorem we can say that
a^2 + b^2 = c^2

we said all side lengths are x so we can put x in for a and b and get

x^2 + x^2 = c^2

2x^2 = c^2

c = x * squareroot(2)

that is the basic fundamental answer that will always work when working with diagonals of squares.

so if the length between bases is 90 ft, we could plug this in and get
c = 90 ft * squareroot(2)
c = 127.28 ft

Answer:

58.91m^2

Step-by-step explanation:

(smaller triangle below)

A=\frac{ab}{2}\\ =\frac{8.6*5.5}{2}\\ =23.65m^2\\\\A=\frac{ab}{2}\\ =\frac{8.6*8.2}{2} \\=35.26m^2

(bigger triangle above)

Since you have both triangle, and all lengths you dont need to worry about calculating the square

Add both together

23.65+35.26\\=58.91m^2

Tasya [4]

Answer:

Total no of ways can the fund raising committee be formed if at least 4 accounting majors are on the committee. = 360

Step-by-step explanation:

Given  -  

A business organization needs to make up a 8 member fund-raising committee.

The organization has 6 accounting majors and 6 finance majors .

Total no of ways can the fund raising committee be formed if at least 4 accounting majors are on the committee.

(1) chose 4 accounting majors  from 6 and chose 4 finance  majors  from 6  =

  =   \binom{6}{4}\times\binom{6}{4}

 =  \frac{(6!)}{(2!)(4!)}\times \frac{(6!)}{(2!)(4!)} = 225

(2) chose 5 accounting majors  from 6 and chose 3 finance  majors  from 6 =  \binom{6}{5}\times\binom{6}{3}

=  \frac{(6!)}{(1!)(5!)}\times\frac{(6!)}{(3!)(3!)} = 120

=

(3) chose 6 accounting majors  from 6 and chose 2 finance  majors  from 6 = \binom{6}{6}\times \binom{6}{2}

= \frac{(6!)}{(6!)(0!)}\times\frac{(6!)}{(2!)(4!)} = 15

Then total no of ways = (1) + (2) + 3

                                       = 360
