It is often more convenient to evaluate a polynomial when it is written is "Horner form."
... f(x) = (((10x -4)x -8)x +3)x -6
The graphs offered can be distinguished by their values of f(1) and f(2), so our table can be a short one.
... f(1) = (((10·1 -4)1 -8)1 +3)1 -6 = -5 . . . . . . . eliminates graph d
... f(2) = (((10·2 -4)2 -8)2 +3)2 -6 = 96 . . . . eliminates graphs a and c
The appropriate choice is b.
Answer:
Area is greater than 
sq ft.
Step-by-step explanation:
Length of rectangular sign board = ft
Width of rectangular sign board = 
ft
Area of a rectangle is given by the formula:
To find the area, we are going to multiply with .
is greater than 1.
Therefore the multiplication will be greater than .
Hence, we can say that area will be greater than sq ft.
Area of the sign:
Answer: B. 2 2/5
Step-by-step explanation: Hope this help :D
Answer:
A= 1/2(2x)(x+7)
Step-by-step explanation:
The correct answer is d.We have the following system of linear equations:
(I)
(II)
Let's use the elimination method, then let's multiply the equation (1)
and subtracting (I) and (II):
(I)
∴
(I)
(II)
____________________
(III)
∴
We can find the value of x by substituting y either in (I) or (II). Thus, from (I):
∴
∴
∴
∴
Let's substitute the values of x and y into (I) and (2)
(I)
(II)
Finally the answer is:
