Answer:
y = 130(24/13)^(x -10)
Step-by-step explanation:
The y-value changes by a factor of 240/130 = 24/13 for a unit change in the x-value. This means we can write the function as though it had an initial value of 130 and a growth factor of 24/13, translated 10 units to the right.
y = 130(24/13)^(x -10)
_____
<em>Additional comment</em>
This can also be written in the form ...
y = a·e^(kx)
where a=130·(24/13)^(-10) ≈ 0.28266, and k=ln(24/13) ≈ 0.61310
Answer:
B. 30
Step-by-step explanation:
The mosaic tile has a trapezoidal shape, so that its area can be determined as follows;
Area of a trapezium = (a + b)h
where: a and b represent the length of its plane sides, and h is the height.
Area of a mosaic tile = (4 + 6) 4
= 10 x 2
Area of a mosaic tile = 20 square inches.
But, Dan wants to cover a 600 square inch area.
So that the number of tiles needed =
= 30
The number of mosaic tiles needed by Dan is 30.
