Answer:
Hello!
for 11 we can put in values
x = 0
y = 12 * 0^2
y=0
One point is (0,0)
x=1
y=12*1^2
y=12
Another point is (1,12)
x=-1
y = 12 * -1^2
y=12
A third point is (-1,12)
This tells us that this is not exponential since an exponential function as a steep curve on one side not two.
You can think of an exponential function as a half parabola if it helps.
13. We can plug in numbers again here.
x=0
y=7(0)+3
y=3
So the first point is (0,3)
x=1
y=7(1)+3
y=10
The second point is (1,10)
x=-1
y=7(-1)+3
y=-4
so the third point is (-1,-4)
This shows that the graph is not exponential it is linear since it goes in a straight line.
15. We just plug in -2 for t so
g(-2) = 2*0.4^-2
0.4^2 is 0.16 * 2 is 0.32 which is the answer
17. We can put 18 for w
h(18) = -0.5*4^18
This is where there is a issue because 4^18 is a extremely small number (6.9 * in scientific notation-
But we can multiply that by -0.5 to get
-3.4 *
which I believe is -0.000000034

Graph the line with the equation y = -1/5 x + 4.
the equation straight line y = -1/5 x + 4. of the line drawn in the picture is attached below.
What is equation straight line?
There are numerous ways to express the equation of a straight line, including point-slope form, slope-intercept form, general form, standard form, etc. A straight line is a geometric object with two dimensions and infinite lengths at both ends. The formulas for the equation of a straight line that are most frequently employed are y = mx + c and axe + by = c. Other versions include point-slope, slope-intercept, standard, general, and others.
Given two line-side coordinates, use the slope formula to determine the slope of the line. The slope is defined as the ratio of the change in the y values to the change in the x values using the formula m=(y2-y1)/(x2-x1).
The given equation y = -1/5 x + 4.
Here m = -1/5
and c= 4
So the plot on the graph will be as fallow.

Solve the system of equations using determinants.
3x + 2y = 7
3x - y = -8
Find the values of determinants D, Dx and Dy
D=?
Dx=?
Dy=?
Answer:
To find the values of determinants, we first need to set up the coefficient matrix and the constant matrix:
Coefficient matrix:
| 3 2 |
| 3 -1 |
Constant matrix:
| 7 |
| -8 |
Now, we can use determinants to solve for the values.
D = | 3 2 | = (3 * -1) - (2 * 3) = -9
| 3 -1 |
Dx = | 7 2 | = (7 * -1) - (2 * -8) = -1
|-8 -1 |
Dy = | 3 7 | = (3 * -1) - (7 * 3) = -24
| 3 -8 |
Therefore, D = -9, Dx = -1, and Dy = -24
90 dL times L/dL equals what
90 dL times L/dL equals 9 L
How to find 90 dL times L/dLTo understand why 90 dL times L/dL equals 90L, it's important to understand the units involved and how they cancel out.
First, dL stands for deciliter, which is a unit of volume equal to one-tenth of a liter.
L, on the other hand, stands for liter, which is a unit of volume equal to 1000 milliliters or one cubic decimeter.
So, 90 dL represents a volume of 90 deciliters, while L/dL represents a ratio of liters to deciliters.
Specifically, L/dL means "liters per deciliter," which is a way of expressing a conversion factor between liters and deciliters.
Multiplying 90 dL by L/dL involves multiplying 90 dL by the conversion factor of L/dL, which is 1 liter per 10 deciliters. The deciliter units cancel out, leaving only the liter units.
Therefore, we can rewrite the calculation as follows:
90 dL x (1 L/10 dL) = (90/10) L = 9 L
So, the result is 9 L, which is equivalent to 90 dL times L/dL.

a salesman earns 25% commission he sells amount to 2450 shillings after giving a buyers 2% discount . calculate his commission. Suppose all the goods were sold at marked price , what would be is earnings?
Answer:
Step-by-step explanation:
A) Commission = 2450 shillings * 25 % = 2450 shillings * (25/100) = 2450 shillings * (0.25) = 612.50 shillings
Commission = 612.50 shillings
B) If the total sale is 2,450.00 shillings, after the seller gives buyers a 2% discount. We must re-enter the discount:
2,450.00 shillings = X - X * 2% = X - 0.02 X --->
------> 0.98 X = 2,450.00 shillings
------>X= 2,450.00 / 0.98
------> X = 2,500.00 shillings
NEW COMMISSION = 2,500.00 shillings * 25 % = 2,500.00 shillings *(25/100) =2,500.00 shillings * (0.25) = 625 shillings
NEW COMMISSION = 625 shillings

When matched, the prompts on asymptotes would be:
Vertical asymptote at x=0: The cost of producing pills can never reach 0.Decreasing on (0,∞): As the number of pills produced gets smaller, the average cost of production greatly increases.Horizontal asymptote at y=0: The cost of producing pills cannot be negative.Positive on (0,∞): As more pills are produced, the average cost per pill decreases.How to match the asymptote statements ?The presence of a vertical asymptote at x=0 signifies that the cost of producing pills can never reach a value of 0, remaining persistently positive. Simultaneously, the horizontal asymptote at y=0 serves as a reassuring indication that the cost of producing pills cannot be negative, as it steadfastly remains at or above zero.

What is orientation?In geometry, how an item is positioned in the space it occupies—such as a line, plane, or rigid body—is described in terms of its orientation, angular position, attitude, bearing, and direction.
It refers more particularly to the fictitious rotation required to shift an object from a reference placement to its present location.
To get to the current positioning, a rotation might not be sufficient.
It could be required to include a fictitious translation known as the object's location (or position, or linear position).
Together, the position and orientation completely explain where the object is situated in space.

Determine the equation of the circle with radius 9 and center ( − 1 , − 8 ).
The equation of the circle with radius 9 and center ( -1,-8 ) is( x + 1 )² + ( y + 8 )² = 81.
What is the equation of the circle?The standard form equation of a circle with center (h, k) and radius r is:
( x - h )² + ( y - k )² = r²
Given that the circle has a center of (-1, -8) and the radius is 9.
Hence; from the standard form of the equation of the circle:
Center ( h , k ) = ( -1, -8 )
h = -1
k = -8
And radius r = 9
Plug these values into the above formula and simplify.
( x - h )² + ( y - k )² = r²
( x - ( -1 ) )² + ( y - ( -8 ) )² = 9²
Simplify
( x + 1 )² + ( y + 8 )² = 81

A piece of wood is in the shape of a rectangular prism with a length of 10 inches, a width of 4 inches, and a height of 5 inches. You cut the wood in half to form two pieces of wood, each with a length of 5 inches. What is the percent increase in the total surface area? Round your answer to the nearest hundredth, if necessary. %
Answer: 18.18%
Step-by-step explanation:
First, let's calculate the surface area of the original piece of wood. The surface area (SA) of a rectangular prism is given by the formula:
\($$SA = 2lw + 2lh + 2wh$$\)
where \(\(l\)\) is the length, \(\(l\)\) is the width, and \(\(h\)\) is the height. For the original piece of wood, \(\(l = 10\) inches\), \(\(w = 4\) inches\), and \(\(h = 5\) inches\).
After the piece of wood is cut in half, the length becomes 5 inches, but the width and height remain the same. So, for each of the two new pieces of wood, \(\(l = 5\) inches\), \(\(w = 4\) inches\), and \(\(h = 5\) inches\). The total surface area of the two new pieces of wood is twice the surface area of one of the new pieces.
The percent increase in the total surface area is given by the formula:
\($$\text{Percent Increase} = \frac{\text{New Total SA} - \text{Original SA}}{\text{Original SA}} \times 100\%$$\)
Let's calculate these values.
The percent increase in the total surface area when the piece of wood is cut in half is approximately 18.18%.

So all natural numbers are often refereed to as cardinal numbers. Cardinal numerals have been used for counting. When an ordinal number is an integer that represents the location or place of an object.
The description of a cardinal number is really a number that is used to express quantity in whole numbers. Decimals and fractions are not regarded as cardinal numbers. Natural numbers and numbering numbers constitute cardinal numbers. Each of them is a positive integer.
