The number of small cubes in each cuboid is:
(a) 3, b) 6, c) 27, and d) 16.
Given are four cuboids.
It is required to find the number of small cubes that are used to make these cuboids.
a) There are only 3 small cubes.
b) There is only one step of cubes.
Number of cubes = 3 + 3 = 6
c) There are 3 cubes arranged horizontally and 3 cubes arranged vertically through each surface.
Number of cubes in one step = 3 × 3 = 9
There are 3 steps like that.
So, total number of cubes = 3 × 9 = 27
d) There are 4 cubes in the horizontal position.
And there are 4 cubes going down.
Total number of cubes = 4 × 4 = 16

Garden Fresh sells 2 turkey sandwiches for $8.50.
Uptown Eatery sells 3 turkey sandwiches for $13.50.
The graph shows Delicious Deli’s turkey sandwich sales, where x represents the number of turkey sandwiches sold, and y represents the total cost.
Answers
Answer:
$4 per Turkey
Step-by-step explanation:
Look on the graph and follow every number to the cost:
2 Turkeys: $8
4 Turkeys: $16
5 Turkeys: $20
Notice how there is a Pattern:
8, 16, and 20 are all multiples of 4
4 x 2 = 8
4 x 4 = 16
4 x 5 = 20
So, the constant of proportionality for the coast per sandwich and Delicious Deli is $4

The initial value of the function is 2.5.
The function increases by a factor of 2.5 for each unit increase in x.
The domain of the function is all real numbers.
The range of the function is all real numbers greater than 3.
Answers
The statements which are true of the function; f(x) = 3(2.5)^x and there explanations are below;
- The function is exponential;Traditional to every exponential function is that the independent variable is usually an exponent of a constant. Hence, we can conclude the function is an exponential function.
- Yes,the function increases by a factor of 2.5 for each unit increase in x. Hence, the slope of the function is; 2.5.
- The domainof the function is all real number, because, the value of y is defined for all real number values of x.
Read more on exponential functions;
This is an exponential function since the x is in the exponent's place instead of in the place of a "regular" variable. The first statement is true.
The initial value of this particular function is 3 (the other number is the multiplier), so choice 2 is NOT true.
The function increases by its multiplier, which is 2.5, so statement 3 is true.
The equation allows us to enter any x value we want to determine the y, so the domain is in fact all real numbers. So, this statement is also true.
If you were to graph this on a calculator, you would see that the range, the "allowed" y values for our function, do not touch or ever drop below the x-axis. That means that the range is all numbers greater than 0. So that statement is false. No matter what value we pick for x, we will NEVER get back a negative y value or that y = 0. For example, if x = 0, y = 3; if x = -5, y = .03; if x = -10, y = .0003; if x = 5, y = 292.97; if x = -100, . Y will never be equal to 0 or less than 0.
