Answer:
Step-by-step explanation:
Since we have given that
Number of styrofoam balls bought by Bradley in May = 48
Number of toy figurines sold in May = 19
Number of styrofoam balls bought by Lupe in June = 44
Number of toy figurines sold in June = 21
So, we need to make a matrix that represents all of their May purchases and their June sales :
So, it is given by
May June
Purchases Sales
Bradley 48 19
Lupe 49 21
Thus, we can define a 2x2 matrix in which row 1 represents Bradley and row 2 represents Lupe. The columns then represent May and June. To distinguish between purchase and sale, we will show sale by a positive number and sale with negative; therefore the final matrix will be
Answer:
1
Step-by-step explanation:
y-y1=m(x-x1)
y1= y-coordinate of a point
(-2,1)
the y-coordinate is 1
Answer: True
Step-by-step explanation:
The length of the sides of a right triangle are always less than the length of the hypotenuse.
Also, the ratio of any side of a triangle and the hypotenuse is always less than 1.

Step-by-step explanation:

The function f(x) = 16 represents the growth of a bee population every year in a remote swamp.
Jennifer want to calculate twice a year so we change 2 to . Also we multiply x by 2
f(x) = 16
f(x) =
f(x)= 16
The function for Jennifer's purpose is f(x)= 16
We know y= a(1+r)^t is exponential growth
where 'r' is the growth rate
From the function we got 1 + r= 1.414
1 + r = 1.414
r = 0.414
Now we multiply by 100
So r= 41%
So growth rate = 41%
