Answer: the perimeter of this L shaped figure is 10 units, so scaling it by 3× would make the perimeter 30 units. so the scale factor is 3

The scale factor of the figure is 3 units.

We need to draw a scaled copy of this polygon that has a perimeter of 30 units and also we need to find the scale factor.

The scale factor is the ratio of one figure's side length to the other figure's corresponding side length.

If the sides of a polygon are changed by a scale factor 'a' then its perimeter is also changed by the same scale factor.

Now, scale factor = Scaled perimeter/Actual perimeter

From the figure, the perimeter of the figure is 10 units.

So, scale factor = 30/10 =3 units

Therefore, the scale factor of the figure is 3 units.

Step-by-step explanation:

5x-3x=18+15-9

2x=42 /:2

Answer:

Y= 2e^(5t)

Step-by-step explanation:

Taking Laplace of the given differential equation:

s^2+3s-10=0

s^2+5s-2s-10=0

s(s+5)-2(s+5) =0

(s-2) (s+5) =0

s=2, s=-5

Hence, the general solution will be:

Y=Ae^(-2t)+ Be^(5t)………………………………(D)

Put t = 0 in equation (D)

Y (0) =A+B

2 =A+B……………………………………… (i)

Now take derivative of (D) with respect to "t", we get:

Y=-2Ae^(-2t)+5Be^(5t)   ....................... (E)

Put t = 0 in equation (E) we get:

Y’ (0) = -2A+5B

10  = -2A+5B ……………………………………(ii)

2(i) + (ii) =>

2A+2B=4 .....................(iii)

-2A+5B=10 .................(iv)

Solving (iii) and (iv)

7B=14

B=2

Now put B=2 in (i)

A=2-2

A=0

By putting the values of A and B in equation (D)

Y= 2e^(5t)

Answer:

There are three servings in 1 pound so there are 8*3 servings in one pound which is 24. Plus an extra serving for the extra 1/3 pound makes for a final answer of 25 servings.

Basically all you have to do is go over (left from the center 5 spots) to -5 and up 3. You do x before y always. Then you put a p there because that is point p. I hope this helps you

Answer: being similar means they are in the same ratio. so x = 12

Step-by-step explanation:

first put it into a ratio, 4/x =2/6 and answer it like an equation.

4/x=2/6 (cross multiply)

24=2x

x=12

Answer:

x = 12

Step-by-step explanation:

The only full "pair" of sides is 2 on the little polygon and 6 on the big polygon. The relationship between them is 3. 2 × 3 = 6

Now, apply this to the pair we are using: 4 × 3 = x

4 × 3 = 12, so x equals 12.

Answer:

The answer is 3.825 inches, the reduced picture will be 84% of the size of the original

Answer:

3.78 inches

Step-by-step explanation:

if the original length is 4.5 and we are making it 84 percent of that size we multiply 4.5 times 84 percent(that is 0.84).

If we type in 4.5 * 0.84 on a calculator the answer comes back as 3.78

so the answer is 3.78 inches

Answer:

Here we have:

IxI < 7

This also can be written as:

-7 < x < 7

and:

IyI < 2.

As above, we can write this as:

-2 < y < 2.

Then the graph of this region will be a rectangular area, where the perimeter is a dashed line (because here we use the strictly smaller or strictly larger symbols)

Such that the vertical component goes from -2 to 2, and the horizontal component goes from -7 to 7.

The area would be the area inside that rectangle, where i did not shade it so it is easier to read.

Answer:

He has 12 ten dollar bills

Step-by-step explanation:

Let t = number of 10 dollar bills

f = number of fifty dollar bills

t+f = 25  since he has 25 bills

solving for f

f = 25 -t

Then we know he has 770 dollars

10t+50f = 770

Using f = 25-t in the above equation

10t + 50 ( 25-t) = 770

Distribute

10t+ 1250 - 50t = 770

Combine like terms

-40t+1250 = 770

subtract 1250 from each side

-40t - 1250-1250 = 770-1250

-40t = -480

divide each side by -40

-40t/-40 = -480/-40

t =12

He has 12 ten dollar bills

Sol:

The current price of item = RM258

The price that increases every month = RM4

Now,

It's price in ten month's line= Current price + 10 X increased price per month

= RM 258 + 10X RM4

=RM 258+ RM 40

= RM 298

Therefore, it's price in ten month's line will be RM 298

Answer:

D

Step-by-step explanation:

So we have the function:

[tex]f(x)=\frac{1}{5}x+4[/tex]

To find the inverse, simply switch x and f(x), change f(x) to f⁻¹(x), and solve for it. Thus:

[tex]x=\frac{1}{5}f^{-1}(x)+4[/tex]

Subtract 4 from both sides:

[tex]x-4=\frac{1}{5}f^{-1}(x)[/tex]

Multiply both sides by 5:

[tex]f^{-1}(x)=5x-20[/tex]

So that's our inverse :)

So, our answer is D

Answer:

Step-by-step explanation:

Answer:

The constant of proportionality is 1/3.

Step-by-step explanation:

You can find this answer by taking two coordinates shown and put them into a fraction form.

Example:

The second coordinate is (2, 6)--> 2/6, which reduced is 1/3.

To test that 1/3 is correct, you can do another coordinate: (4, 12)-->4/12, which reduced is also 1/3.

So 1/ 3 is correct.

Or take a look at the graph...

the red lines are always two units across, and the blue lines are always six units in height. So 2/6, (length, height), which can be reduced to 1/3, the constant of proportionality.
