Is a relation always a function ? is a function always a relation ? explain

1 answer:

3 0

It just so happens that it's always the same y for each x, but it is only that one y. So this is a function; it's just an extremely boring function! ... So this is a relation, but it is not a function.

What is solution of 5+3(y-4)=5(y+2)-y

gulaghasi [49]

Answer:

y = -17

Step-by-step explanation:

5 + 3(y - 4) = 5(y + 2) - y Distribute

5 + 3y -12 = 5y + 10 - y Combine like terms

-7 + 3y = 4y + 10

+7 +17 Add 17 to both sides

3y = 4y + 17

-4y -4y Subtract 4y from both sides

-y = 17 Divide both sides by -1

y = -17

A diving board is 10 feet above the surface of the water. At time t = 0, the board propels Chris upward at a rate of 12 feet per

Art [367]

Answer:

Chris will take 0.75 seconds to return to his starting height of 10 feet.

Step-by-step explanation:

Let the height of Chris be represented by $h(t) = -16\cdot t^{2}+12\cdot t +10$ , where $h(t)$ is the height in feet and $t$ , the time in seconds. First, we equalize the formula to a height of 10 feet and simplify the resulting expression, that is:

$-16\cdot t^{2}+12\cdot t +10 = 10$

$-16\cdot t^{2}+12\cdot t = 0$

Then, we simplify the expression by algebraic means:

$-16\cdot t\cdot \left(t-\frac{3}{4} \right) = 0$

Roots of the polynomial are, respectively:

$t = 0\,s\,\lor \,t = 0.75\,s$

First root represents the initial height of Chris, whereas the second one represents the instant when Christ returns to the same height above the surface of the water. Hence, Chris will take 0.75 seconds to return to his starting height of 10 feet.
