Answer:
$34.5
Step-by-step explanation:
Turning the 3/4 into a decimal would be .75, .75 can go into 7.5 10 times. You would multiply 10 by the cost $3.45 and you would get $34.5 for 7.5 lbs of walnuts.
Answer:
The exponential equation is;
y = 0.1•0.5^x
Step-by-step explanation:
Here, we want to get the exponential function represented by the table
Mathematically, the general form of an exponential function is;
y = a•b^x
By getting a and b, we have the exponential function
We can use any of the points;
Let us start with (0,0.1)
0.1 = a•b^0
anything raised to zero is 1
0.1 = a * 1
a = 0.1
Now, we have a
Let us work with the second point to get b
The point is (1,0.05)
0.05 = 0.1•b^1
0.05 = 0.1b
b = 0.05/0.1
b = 0.5
Thus, we have the equation as;
y = 0.1•0.5^x
9(10)=90
8(9)=72
7(8)=56
6(7)=42
5(6)=30
4(5)=20
3(4)=12
3=12
If the one factor of the function is (x - 4). Then the other two factor of the function will be (2x + 1) and (x + 1).
<h3>What is a factorization?</h3>
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
(x - 4) is the factor of the function.
f(x) = 2x³ - 5x² - 11x - 4
Then the factor of the function will be
f(x) = 2x³ - 5x² - 11x - 4
f(x) = 2x³ + x² - 6x² - 3x - 8x - 4
f(x) = x²(2x + 1) - 3x (2x + 1) - 4(2x + 1)
f(x) = (2x + 1)(x² - 3x - 4)
f(x) = (2x + 1)(x² - 4x + x - 4)
f(x) = (2x + 1)[x(x - 4) + 1 (x - 4)]
f(x) = (2x + 1)(x + 1)(x - 4)
