If the range of f(x)= square root mx and the range of g(x)=m square root x are the same, which statement is true about the value

AveGali [126]

M can be any positive real number.

Explanation:

From f(x) = √(mx) ; if x is posive m has to be positive; if x is negative m has to be negative; if x is cero m can have any value, and the range will always be 0 or positve

From g(x) = m √x; x can only be 0 or positive and the range will have the sign of m.

Given we concluded that the range of f(x) can only be 0 or positive, then me can only be 0 or positive.

Archy [21]

Answer:

Step-by-step explanation:

B is the correct answer. Since Mrs. Hooper and Mr. Anderson had to call a total of 8 parents, you know the first equation must be either A or B (H + A = 8).

Since you know that Mrs. Hooper had to call 2 more parents than Mr. Anderson, the equation will have to have H + 2 on one side; that's how you know the correct answer is B.

Zack has been planting young trees in his garden. The maple tree that is 42 inches tall is growing 1 inch per month, whereas the

In 16 months, two trees will be of same height

The trees will be of 58 inches tall

Solution:

Let "x" be the number of months

The maple tree that is 42 inches tall is growing 1 inch per month

Thus, equation for maple tree is given as:

Maple tree : 42 + 1 inch (number of months)

Maple tree : 42 + x ------- eqn 1

The oak tree that is 10 inches tall is growing 3 inches per month

Thus, equation for oak tree is given as:

Oak tree : 10 + 3 inch (number of months)

Oak tree : 10 + 3x -------- eqn 1

For two two trees to be equal in height, equate eqn 1 and eqn 2

$42 + x = 10 + 3x\\\\3x - x = 42 - 10\\\\2x = 32\\\\x = 16$

Thus, in 16 months, two trees will be of same height

What will that height be?

Substitute x = 16 in any one eqn

$10+3x = 10 + 3(16) = 10+48 = 58$

Thus the trees will be of 58 inches tall
