Usually, you're asked to model a situation with an equation. Here, you're given the equation and asked what situation it models.
The features of the equation that are of interest are ...
- multiplication of the unknown value by 17.35
- comparison of that product to 624.60, expecting the product to be greater than that value
The first two offered scenarios involve addition of an unknown value, not multiplication.
The third offered scenario compares a purchase price to a budget amount. Answering a question like this involves a "less than" comparison, not a "greater than" comparison.
The last offered scenario involves finding a variable value that will result in the product 17.35x exceeding 624.60—exactly what the given inequality models.
The appropriate choice is ...
... J Daren earns $17.35 ...
Answer:
3x³ + 13x² + 14x
Step-by-step explanation:
(f × g)(x)
= f(x) × g(x)
= (x + 2)(3x² + 7x)
= x(3x² + 7x) + 2(3x² + 7x) ← distribute parenthesis
= 3x³ + 7x² + 6x² + 14x ← collect like terms
= 3x³ + 13x² + 14x
The answer is 0 because you replace the x in the equation with 3 and 2•3=6 6-6=0
It is 9/4π ft².
Since the central angle is 40°, this is 40/360 = 1/9 of the circle.
The area of the circle is given by A=πr²; since r=9/2, we have
A=π(9/2)² = 81/4π
Multiplying this by 1/9,
81/4π(1/9) = 81/36π = 9/4π
Answer: -2, 2, 7/4
