To solve this, we must see a ratio between 3 hours and 15 hours.

12/3=x/15
15 is 5 times larger than 3. Therefore, if we multiply 12 by 5, we will know how many bracelets Ana can make.

12×5= 60

Therefore, 60 bracelets can be made in 15 hours

The function y=e−3x is vertically stretched by a factor of 4, reflected across the y-axis, and then shifted up 5 units, find the

olya-2409 [2.1K]

Answer:

Step-by-step explanation:

y = e^(-3x)

Stretch by factor of 4

y = 4e^(-3x)

Reflect across y axis

y = 4e^(3x)

Shift up by 5

y = 4e^(3x) + 5

If BE = 2x + 2, BD = 5× - 3, and AE = 4× - 6, what are the values of x and AC?

hichkok12 [17]

Answer:

x = 7

AC = 44

Step-by-step explanation:

Find the diagram attached

According to the parallelogram,

BD = 2BE

5x-3 = 2(2x+2)

5x-3 = 4x+4

5x-4x = 4+3

x = 7

Hence the value of x is 7

Also AC = 2AE

AC = 2(4x-6)

AC = 8x - 12

AC = 8(7) - 12

AC= 56-12

AC = 44

Hence the measure of AC is 44

Lunna [17]

Answer:

( - $\sqrt{3}$ /2 , -1/2)

Step-by-step explanation:

-210 degrees in standard position corresponds to an angle in the 3rd quadrant 30 degrees below the negative x-axis

The hypotenuse of the triangle here is 1, and we want the coordinates.
