Write an exponential function in the form y=ab^xy=ab
Juliette [100K]

Answer:

y=20(6)^x

Step-by-step explanation:

hello :

the graph passes through the point (0,20) : when x=0  and  y=20  :

20= ab^0    so a=20 because : b^0 = 1

the graph passes through the point (3,4320) : when x=3.  and  y=4320  : 4320= ab^3  but : a=20   so : 4320 = 20b^3

so : b^3 = 4320/20 = 216...... 216 =  6^3

b^3 = 6^3

b=6

the function is : y=20(6)^x

A side of a square is 10 cm longer than the side of an equilateral triangle. The perimeter of the square is 3 times the perimete
bija089 [108]

Here's the solution :

  • Side of the equilateral triangle = x

  • Side of square = x + 10

perimeter of equilateral triangle = 3 × x = 3x

perimeter of square = 4 × (x + 10)

now, according to above statement :

permission (square) = 3 × perimeter (triangle)

that is :

  • 4(x + 10)  = 3 \times 3x

  • 4x + 40 = 9x

  • 9x - 4x = 40

  • 5x = 40

  • x = 8

therefore, side of triangle = 8 cm

  • perimeter (triangle) = 8 × 3 = 24 cm

  • side of square = 8 + 10 = 18 cm

  • perimeter of square= 18 × 4 = 72 xm
