A.) Evaluate f(0)

Thanks fam

Answers

The piece wise function is written that if X is ≤1 use the top equation and if x is > 1 use the bottom equation.

f(0) means that X is = 0, so you would use the top equation:

x^2

Replace x with 0 to get 0^2 which is 0 x 0 = 0

F(0) = 0

$(1)/(2) = 0.5$
$(5)/(10) = 0.5$

∴ $(1)/(5) = (5)/(10)$

Answer:

Step-by-step explanation:

1/2 = 0.5

5/10 = 0.5

So 1/2 = 5/10

For every 3.3 km rock is buried, the pressure placed upon it increased 0.1 gigapascals. If rock undergoing metamorphosis is buried at 16 km what is the pressure placed on that rock?

Answers

For every 3.3 km rock is buried, the pressure placed upon it increased 0.1 Giga pascals.

We need to find the pressure placed on that rock at 16 km.

Let us divide 16 km by 3.3 first to find the number of 0.1 Giga pascals would be there.

16/3.3.

On dividing 16 by 3.3, we get 4.8485.

In order to find the number the pressure placed on that rock, we need to multiply 0.1 by 4.8485, we get

0.48485 Giga pascals.

Therefore, if rock undergoing metamorphosis is buried at 16 km, 0.48485 Giga pascals is the pressure placed on that rock.

If y varies directly as x, and y is 6 when x is 72, which is the value of y when x is 8 ?

Answers

$(y)/(x) = k$

$(6)/(72) = k$

$(1)/(12) = k$

********************************

$(y)/(x) = k$

$(y)/(8) = (1)/(12)$

12y = 8

$y = (8)/(12)$

$y = (2)/(3)$

y = $(2)/(3)$

given y ∝ x

To convert to an equation multiply by k the constant of variation

y = kx

to find k use the given condition y = 6 when x = 72

y = kx ⇒ k = $(y)/(x)$ = $(6)/(72)$ = $(1)/(12)$

equation is → y = $(1)/(12)$ x

when x = 8 then

y = $(1)/(12)$ × 8 = $(8)/(12)$ = $(2)/(3)$
