marysya [2.9K]

Answer:

k = 2

Step-by-step explanation:

Take some reference points on the graph of f and g:

f(2) = 1, g(2) = 2
f(4) = 2, g(4) = 4
f(8) = 4, g(8) = 8

According to the numbers above we can state:

g(x) = 2f(x)

So the value of k is 2

On a school trip, the ratio of the teachers to students is 2:21. The ratio boys to girls is 4:3. If there are 18 girls girls on

Alexandra [31]

Answer:

Step-by-step explanation:

Let's say B is the number of boys and T is the number of teachers.

T / (B + 18) = 2/21

B/18 = 4/3

Solve the second equation for B.

B = 24

Plug into the first equation to find T.

T / (24 + 18) = 2/21

T = 4

What are the zeros of the function f(x)=-x^2+13x-36

Galina-37 [17]

For this case we have the following function:

$f (x) = - x ^ 2 + 13x-36$

To find the zeros of the function we make $y = 0$ and solve for "x", then:

$0 = -x ^ 2 + 13x-36$

We multiply by -1 on both sides of the equation:

$0 = x ^ 2-13x + 36$

We factor the equation, for this we look for two numbers that, when multiplied, result in 36 and when added, result in -13. These numbers are -9 and -4.

$(-9) * (- 4) = 36\\-9-4 = -13$

Thus, the factored equation is:

$(x-9) (x-4) = 0$

Therefore, the roots are:

$x_ {1} = 9\\x_ {2} = 4$

Answer:

$x_ {1} = 9\\x_ {2} = 4$
