You perform a study to determine the depth at which a species of submerged aquatic plant grows the fastest. You conduct the study in a natural lake that has a large population of the plant growing at various depths. You measure the growth rate of a subset of the plant population (five plants) growing at each depth. You find that at a depth of 0 to 49 cm, the plants grow at rates of 1.6, 0.8, 0.4, 1.1, and 1.3 cm/day. At 50 to 99 cm, plants grow at rates of 1.2, 1.4, 1.5, 1.6, 1.9 cm/day. At 100 to 149 cm, plants grow at rates of 1.9, 2.3, 2.2, 2.5, 2.3 cm/day. Finally, at 150 to 199 cm, plants grow at rates of 1.5, 1.3, 1.6, 1.7, 1.1 cm/day. At which depth do plants have the greatest variance in the rate at which they grow?

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

the answer would be c:   ax + b = ax + c

step-by-step explanation:

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.
