Answer:

13.6 (Answer C)

Step-by-step explanation:

I think you meant  f(n) = 0.4 * f(n-1) + 12, where * represents multiplication.

Then f(2) = 0.4 * (4) + 12, or 1.6 + 12, or 13.6.

Answer:

Assuming you have f(n)=0.4f(n-1)+12 with f(1)=4, the answer is f(2)=13.6.

Step-by-step explanation:

I think that says f(n)=0.4f(n-1)+12 with f(1)=4.

Now we want to find f(2) so replace n with 2:

This gives you:

f(2)=0.4f(2-1)+12

f(2)=0.4f(1)+12

f(2)=0.4(4)+12

f(2)=1.6+12

f(2)=13.6

Answer:

1.6

Step-by-step explanation:

First things first is to find what line QP corresponds with which is line MN

After that you find what multiplied into 5 would make it 2. The easiest way of ding so is to divide 2 by 5 which is 0.4. Now you want to find what line PR corresponds with which is OM. Now you multiply 4 (length of line OM) by 0.4 to find the length of line PR which is x. So now line PR is equal to 1.6 and x. Which also means that x=1.6

Answer:

It's actually an  enlargement  of the figure.

Step-by-step explanation:

Because if the figure originally was M' (-2,2), S' (4,2), V' (2, -2). And now the shape is M (-3, 3), S (6, 3), V ( 3, -3). This means that the Triangle got bigger.

The scale factor of the smaller shape inside of the bigger shape is 2 and the scale factor of the bigger shape is 3 making the bigger shape well bigger.

When given the equation y = 3/4x − 6 , Find the x intercept and y intercept.
STALIN [3.7K]

Answer:

the y-intercept is (0,-6)

the x-intercept is (8,0)

Step-by-step explanation:

<em>Solving for the y-intercept:</em>

Since the equation 'y=3/4x - 6' is in the 'y=mx + c' form (where m is the slope and c is the y-intercept):

3/4 is m (which is the slope)

-6 is c (which is the y-intercept)

<em>Solving for the x-intercept:</em>

When the line intersects with the x-axis, the y-value is 0. Hence, the coordinate is (x,0). Substituting this into 'y=3/4x - 6':

0 = 3/4x - 6

3/4x - 6 + 6 = 6

3/4x = 6

x = 4/3 * 6

= 8

Hence,

the y-intercept is (0,-6)

the x-intercept is (8,0)

<em>Hope this helps and be sure to have a wonderful time ahead at Brainly! :D</em>
