First of all, remember that one ton= 2000 pounds.
Since the adult whale weighs 120 tons, multiply this by 2000 to find the number of pounds. 120*2000=240,000 pounds.
A baby whale weighs 1/40 of the adult whale's weight. Multiply 1/40 times 240,000 to find the total weight in pounds of the baby whale.
The baby whale weighs 6000 pounds.
Answer:
2
Step-by-step explanation:
add 5 to 13 then divide 9 by that number and that is what x equals
Step-by-step explanation:
Opposite means opposite sign.
Reciprocal means inverse (flip the fraction).
The opposite reciprocal of 2/5 is -5/2.
Answer:
slope = - 3
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 3, 8) and (x₂, y₂ ) = (1, - 4)
m = 
= 
= - 3
Answer:
D. f(x) = -6x^3 -5x^2 +21x
Step-by-step explanation:
The given zeros mean the function has factors ...
(x -(-7/3))(x -3/2)(x -0)
Multiplying by 6, we can write this as ...
(3x +7)(2x -3)(x) = 6x^3 +5x^2 -21x
And multiplying by -1 gives ...
-6x^3 -5x^2 +21x . . . . . matches choice D

<em>Additional comment</em>
The product of factors will be zero when f(x) = 0. This means we can multiply or divide by any convenient factor and the product will remain zero. Effectively, we have multiplied our original factorization by -6 to make the expression match one of the given forms. When we write this final expression as the function f(x), it remains true that the given zeros are zeros (x-intercepts) of f(x).
