How To Find the surface area for a normal prism
To find the surface area of a prism, use the formula SA=2B+ph, where SA stands for surface area, B stands for the area of the base of the prism, p stands for the perimeter of the base, and h stands for height of the prism.
Explanation: To find surface area of the rectangular prism.
The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
Shapes.
Right rectangular prisms or cuboids are all around us. A few examples are books, boxes, buildings, bricks, boards, doors, containers, cabinets, mobiles, and laptops. Non-examples of a right rectangular prism: This shape is a prism but its top and base do not have right angles in the shape.

The graph shows the distance, y, in miles, of a moving motorboat from an island for a certain amount of time, x, in hours:
A graph titled Distance Vs Time is shown, with Time in hours labeled on x axis and Distance from Island in miles labeled on y axis. The scale on the x axis shows the numbers 1, 2, 3, 4, 5, 6, 7, and the scale on the y axis shows the numbers 0, 22, 44, 66, 88, 110, 132, 154, 176, 198. The graph shows a straight line joining the ordered pairs 0, 22, and 1, 66, and 2, 110, and 3, 154, and 4, 198.
What is the speed of the motorboat?
198 miles per hour
22 miles per hour
44 miles per hour
66 miles per hour
Using linear function concepts, it is found that the speed of the motorboat is of 22 miles per hour.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.In this problem, each second, the position increased by 22, hence the slope is of 22. Since velocity is the distance divided by the time, which in this problem is the slope, the speed of the motorboat is of 22 miles per hour.

Determine whether or not f is a conservative vector field 3x^2 -5y^2
The given vector Field f(x,y)= [tex]3x^{2} - 5y^{2}[/tex] is not Conservative.
What is Conservative Vector Field?A conservative vector field is a vector field that is the gradient of some function.
The integral is independent of the path that C takes going from its starting point to its ending point.
We know that , the function F conservative if
[tex]\frac{ dP}{dy}[/tex] = [tex]\frac{dQ}{dx}[/tex]
If we prove opposite of this then the function F is not conservative
We have given function , f(x,y)= [tex]3x^{2} - 5y^{2}[/tex]
let P(x,y) = [tex]3x^{2} - 5y^{2}[/tex] and Q (x,y) =0
Now, [tex]\frac{dP}{dy}[/tex] = -10y
and, [tex]\frac{dQ}{dx}[/tex] = 0
Since [tex]\frac{dP}{dy}[/tex] ≠ [tex]\frac{dQ}{dx}[/tex]
Hence, the field is not conservative.

The area of the figure is __ square units.
Answer:
26
Step-by-step explanation:
First, let's find the area of the box on top. 5*2 is 10. We can see that there is another identical box, so we can multiply the area of one box (10) by 2 to get 20. Now we need to find the middle box. 3*2 is 6. All we have to do now is add all the boxes' areas together. This would be 20+6 (10+10+6), which gives us our answer, 26.

The equation of the straight line which has a gradient of -2 and passes through (1, 7) is y = -2x + 9.
How to get the slope-intercept form of a straight line equation?The slope-intercept form of the equation
y = mx +c
Here
m is the slope
c is the y-intercept
To find the slope of a line, we find the rate at which the value of 'y' is increasing as we increase the value of 'x' by one unit.
Substituting the point (1, 7) and m = -2 to determine the y-intercept
y = mx +c
7 = (-2)1 + c
c = 7 + 2
c = 9
Thus, the equation of a line using the slope-intercept form is
y = mx +c
m= -2
c = 9
y = -2x + 9
Therefore, we conclude that the equation of a line using the slope-intercept form is y = -2x + 9.

Southwest Dry Cleaners believes that it will need new equipment in 6 year. The equipment will cost $26,000. What lump sum should be invested today at 10 percent compounded semiannually, to yield $26,000?
The amount will be equal to $14478.22.
What is compound interest?Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-
A = P (1+R/2)^2t
Where, A = Amount after 6 years = $26,000; P = Amount invested now; R = Annual rate of earning = 10% = 0.06; t = time = 6 years.
Substituting;
[tex]26000 = P(1+\dfrac{0.1}{2})^{2*6}=P(1.7958)[/tex]
Therefore, P = 26000/1.7958 = $14478.22

The best prediction for the number of cells in the colony at 16 hours will be 2300. Then the correct option is B.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
The table is given below.
Time (hours) Cell population
0 125
2 162

10 763
Then the equations are given as,
125 = a ...1
763 = ab¹⁰ ...2
From equations 1 and 2, then we have
b¹⁰ = 763/125
b² = 6.104
b = 1.2
Then the equation is given as,
y = 125(1.2)ˣ
Then the best prediction for the number of cells in the colony at 16 hours will be
y = 125(1.2)¹⁶
y = 2311.05
y ≈ 2300
The best prediction for the number of cells in the colony at 16 hours will be 2300. Then the correct option is B.
