Answer:

f(x) = 4(\frac{2}{3})^{x}

Step-by-step explanation:

The first function is given as, f(x) = \frac{1}{2}(\frac{3}{2})^{x}.

Now, the value of this function increases i.e. value of f(x) increases as the x-value increases because \frac{3}{2} > 1.

Now, the second function is given as, f(x) = \frac{1}{2}(- \frac{3}{2} )^{x}.

This function can not be considered as a continuous function because - \frac{3}{2} < 0.

Again, the third function is given as, f(x) = 4(- \frac{2}{3})^{x}.

This function can also not be considered as a continuous function because - \frac{2}{3} < 0.

Finally, the fourth function is given to be, f(x) = 4(\frac{2}{3})^{x}.

In this function, the value of f(x) continuously decreases as the value of x increases, because 0 < \frac{2}{3} < 1.

Therefore, this function represents exponential decay. (Answer)

One morning, the temperature was -5 ferenhight. By noon, the temperature had increased 12 degrees. What was the temperature at n
Papessa [141]

Answer:

Noon\ Temperature = 7F

Step-by-step explanation:

Given

Initial Temperature = -5F

Change (by noon) = 12 degrees

Required

Determine the temperature at noon

The temperature by noon is calculated as thus;

Noon\ Temperature = Initial\ Temperature + Change

Substitute values for Initial temperature and change

Noon\ Temperature = -5F + 12

Noon\ Temperature = 7F

Hence, the temperature at noon is 7F

Nazri put some nails into a box and the total mass was 4 kg. Hari put some
-Dominant- [34]
Answer: a). 3kg b). 1kg

Explanation:

let x be the mass of nails
let y be the mass of the box

We can write an equation base on the information:

x + y = 4kg
3x + y = 10kg (screw is 3 times heavier than nail)

We can solve this system of equation using elimination method to find x:

3x + y = 10
x + y = 4
——————
3x + y = 10
-1(x + y = 4)
——————
3x + y = 10
-x - y = -4
——————
2x = 6
x = 6/2 = 3

Now that we have x we can find y:

3x + y = 10
3(3) + y = 10
9 + y = 10
y = 1
