Answer:

Vertically compressed by 1/9 not 3

Step-by-step explanation:

See picture attached to see comparison. The parent graph is black and the new graph is red. By adding 1/3 to the graph, the parabola becomes more compressed and wider. It is vertically compressed to become wider.

Answer:

B. The graph of g(x) is the graph of g(x) is the graph of f(x) horizontally stretched by a factor of 3.

Step-by-step explanation:

Horizontal shifting right by c units,

(x,y)\rightarrow (x-c,y)

Horizontally stretched by factor c.

(x,y)\rightarrow (\frac{x}{c},y)

Vertically stretched by factor c. ( where, 0< |c|<1 )

(x,y)\rightarrow (x,cy)

Horizontally compressed by a factor of c. ( where, |b| > 1 )

(x,y)\rightarrow (cx,y)

Here,

f(x) = x^2

When f(x) is shifted 1/3 unit right,

Then, the transformed function is,

g(x) = (x-\frac{1}{3})^2

When f(x) is stretched horizontally by the factor of 3,

Then, the transformed function is,

g(x)=(\frac{1}{3}x)^2

When, f(x) vertically stretched by a factor of 3,

Then, the transformed function is,

g(x)=3(x)^2

When, f(x) is horizontally compressed by a factor of 3,

Then, the transformed function is,

g(x)=(3x)^2

Hence, option B is correct.

A population of bacteria is growing at a rate of 20% per hour. If the population starts at 320, what is it an hour later?
gtnhenbr [62]

Answer:

384.

Step-by-step explanation:

The population is given by the expression;

Y(t) = Pr^{t}

Where;

Y(t) is the number of bacteria at time, t.

P is the starting amount.

r is the growth rate.

Given that, P = 320, r = 20% = 0.2, t = 1

Substituting the parameters into the equation;

Y(t) = Pr^{t}

Y(1) = 320 * 0.2¹

Y(1) = 320 * 0.2

Y(1) = 64.

Therefore, the population of bacteria increases hourly by 64.

An hour later; 320 + 64 = 384.

Answer:

A: 68.25 minutes

B: 12 times

C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.

Step-by-step explanation:

a: 72 -0.75*5 = 68.25

b: M=63=72-0.75n

subtract 72 from each side: -9 = -0.75n

divide each side by -0.75: n = 12

so 12 times

c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.
