Answer: The required values are
f(-2) = 120, f(0) = 64 and f(1) = 84.
Step-by-step explanation: We are given the following function f(x) :
We are to find the values of the following :
To find the values of the function at the given points, we need to substitute the corresponding values of x in equation (i).
Substituting x = -2 in equation (i), we get
Substituting x = 0 in equation (i), we get
Substituting x = 1 in equation (i), we get
Thus, the required values are
f(-2) = 120, f(0) = 64 and f(1) = 84.
Answer:
-72a^3 +108a^2
Step-by-step explanation:
(2a)(6a)(2a-8a+9)= (2a)(6a)(-6a+9)=12a^2(-6a+9)
= -72a^3 +108a^2
Answer:
The total cost is <em>28.26.</em>
Step-by-step explanation:
The radius of the birdbath is <em>1.25 feet.</em>
The cost per foot is <em>3.6</em> .
<em>The formula for perimeter of circle is given by,</em>
<em>= 2πR , where R is the radius of circle.</em>
Inserting the above value of radius in the equation above,
circumference = 2(π)(1.25) = 2(3.14)(1.25) = 7.85 
Thus the total cost is,
= (7.85)(3.6) = 28.26
Answer:
W
Step-by-step explanation:
the rule of a 90⁰ counterclockwise rotation is (x,y) -> (-y,x)
For example, if you rotated a point at (3,2) by 90⁰ counterclockwise. You would change it to (-2,3).
Answer:
$1.92
Step-by-step explanation:
To find the cost per bag we divide the total cost by the amount of bags so:
$5.75 / 3 = $1.91666667 per bag, which we can round up to $1.92 per bag.
