Answer: 16y² - x²
Step-by-step explanation: The - sign means a difference, so the choices with + signs are eliminated (though 64x² and 9 are squares)
10 is not a square so that one is eliminated (though the y² and the 4x² are squares)
16 is the square of 4, y² is the square of y, and x² is the square. That expression shows a difference of squares.
Answer:
Step-by-step explanation:
Mr Thomas earns 18.80 per hour for the first 40 hours of work in a week. This means that the total amount that he earned in the first
40 hours of work would be
40 × 18.8 = $752
He earns 1 and a half times and that amount per hour for each hour he works over 40 hours in a week. This amount per hour would be
1.5 × 18.8 = $28.2
Last week, Mr Thomas worked 45.5 hours. The extra hours that he worked is 45.5 - 40 = 5.5 hours.
Amount earned for 5.5 hours is
5.5 × 28.2 = $155.1
Total amount that Mr Thomas earned is
752 + 155.1 = $907.1
yes it does have enough to cover the cube
Answer:
$23.27

yes
Answer:
The value of f(1) is smaller than the value of f(3)
Step-by-step explanation:
<u><em>The correct question is</em></u>
Given the function f(x) = 2x^2 + 3x + 10, find f(1) and f(3). Choose the statement that is true concerning these two values.
The value of f(1) is the same as the value of f(3).
The value of f(1) cannot be compared to the value of f(3).
The value of f(1) is larger than the value of f(3).
The value of f(1) is smaller than the value of f(3)
we have
step 1
Find out the value of f(1)
substitute the value of x=1 in the function f(x)
so
For x=1
step 2
Find out the value of f(3)
substitute the value of x=3 in the function f(x)
so
For x=3
step 3
Compare the values
37> 15
so
f(3) > f(1)
or
f(1) < f(3)
therefore
The value of f(1) is smaller than the value of f(3)
