The product that is undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.
<h3>What is the matrix about?</h3>
Looking at the product of matrix, note that to multiply the two matrix, the column of the first matrix needs to have the same or equal to the row of the 2nd matrix.
And in this case (propensity), it is not satisfied by the first option because:
C = 3 x 1 and
O= 2 x 1 matrix
In this case CD is therefore undefined.
So we can say that The product that is undefined is known a CD, where C is a 3 x 1 matrix and D is a 1 x 2 matrix.

Answer:
5x2+6x-6=0
Step-by-step explanation:
Standard form is ax2+bx+c=0
We add 6x to both sides and we get:
5x2+6x-6=0
Answer:
x = 3
Step-by-step explanation:
From the table of values
f(x) = g(x) = - 2 when x = 3 in both cases
Answer:
<h2>
4</h2>
Step-by-step explanation:
Given the function 2x³ + 5x² + 4x + 8. In order to evaluate the value of the function at x = -2 we will substitute the value of x given into the function as shown;
F(x) = 2x³ + 5x² + 4x + 8
at x = -2
f(-2) = 2(-2)³ + 5(-2)² + 4(-2) + 8
f(-2) = 2(-8) + 5(4) +(-8) + 8
f(-2) = -16+20-8+8
f(-2) = -16+20
f(-2) = 4
The value of the function when x = -2 is 4
Answer:
N = 7.5 pounds
Step-by-step explanation:
Formula for the radioactive decay is given by,

Here, N = Final amount
N₀ = Initial amount
λ = Decay constant
t = Duration of decay
Now we can substitute the values from the given question,
N = 
N = 
N = 15(0.5)
N = 7.5 pounds
