Answer:

y=-3/4x+3

Step-by-step explanation:

subtract 3x from both sides:  4y=-3x+12

Divide both sides by 4:  y=-3/4y+3

The function y=0.3^x represents exponential growth with the initial value equal to 1, the decay factor equal to 0.3, and the rate equal to 0.7.

<h3>Population Growth Equation</h3>

The formula for the Population Growth Equation is:

P_f=P_o*(1+\frac{R}{100}) ^t

           

Pf= future population

Po=initial population

r=growth rate

t= time (years)

growth or decay factor =  (1 ±r)

When 1+R  > 1, the equation represents growth, while 1+R < 1 the equation represents decay.

The question gives:

y=0.3^x, then

Pf=y

Po= 1  

(1+\frac{R}{100}) =0.3 , thus

(100+R}) =30\\ \\ R=-100+30\\ \\ R=-70

r= -70%= -0.7

decay factor= (1-0.7)=0.3

Therefore,

1+R will be = 1+(-0.7)=1 - 0.7 =0.3

When 1+R >1, the function represents exponential growth.

Let f(x) = -­2x ­- 7 and g(x) = ­-4x + 3. Find (f o g)(-­5)
musickatia [10]
The answer is:  [A]:  " -53 " .
_______________________________________________________
Explanation:
_______________________________________________________
Given:  

" Let f(x) = -­2x ­−<span> 7 and g(x) = ­-4x + 3.  Find (f o g)(-­5) " ;
_______________________________________________
First, find g(-5) .   g(x) = -4x + 3.  

g(-5) = -4*(-5)  + 3 = 20 + 3 = 23 ;
_______________________________________________
Now find f (g(-5) to get the answer; that is f(23); 
_______________________________________________
  Find f(23).  f(x) = -2x </span>− 7 .  
 
  f(23) = (-2*23) − 7 = -46 <span>− </span>7 = -53 ; which is "Answer choice: [A]" .

The equation of motion of a block with mass m = 8 kg. attached to a spring whose spring Constant is k = 2 and which starts from
Annette [7]

Answer:

FALSE

Step-by-step explanation:

In order to be consistent with the system of unit we should decide if we are going to work with the CGS system <em>(centimeter-gram-second)</em> or the MKS system <em>(meter-kilogram-second). </em>

If we decide to work with the CGS system, the equation of motion would be

8,000x ′′ + 2x = 0; x(0) = 3, x ′ (0) = 0

since 1 Kg = 1,000 g

If we decide to work with the MKS system, the equation of motion would be

8x ′′ + 2x = 0; x(0) = 0.03, x ′ (0) = 0

given that 1 mt = 100 cm

Which absolute value function, when graphed, represents the parent function, f(x) = |x|, reflected over the x-axis?
Gala2k [10]
Reflecting the point (x, y) over the x-axis transforms it to the point (x, -y). Then the points (x, f(x)) on the graph of f(x) will be transformed to (x, -f(x)) when the graph is reflected over the x-axis.

The reflection of the function f(x) = |x| is -f(x) = -|x|. If we name the reflected function f(x), we have
  f(x) = -|x|
