A compound interest formula is a type of exponential equation. That is option C
What are exponential equations?Exponential equations are those equations that has their variables as exponents. A typical example of this type of equation is the compound interest formula.
The compound interest formula is an exponential equation because the little sum invested as capital, once the interest is added, the balance will earn more capital during the next compounding period.
Therefore, a compound interest formula is a type of exponential equation.

Step-by-step explanation:
well, if you remember P.E.M.D.A.S, which is the order for doing equations, the first two dont matter, but from M for Multiplication, D for Division, A for addition, and finally S for Subtraction, those are the ones that you need here. So you divide the 9s first giving you 9-1+9-1=8+8=16.

Fill in the missing numbers to complete the linear equation that gives the rule for this table.
X Y
5 -5
6 -6
7 -7
8 -8
Y=___x + ___
Answer:
y = -x +0
Step-by-step explanation:
y = mx + b
y= slope * x + y-intercept
To find slope, use any x and y pair from the table, for example (x= 5, y= -5)
slope = y/x = -5/5 = -1
y= -x + b
To find b the y-intercept, substitute any x and y pair from the table, for example (x= 5, y= -5)
-5 = -5 +b
b = 0
The linear equation that gives the rule for this table is
y = -x + 0 or just y = -x

Find constants a and b such that = (axy + z3) i + (3x2 – z)j+-y)k is irrotational. Also find a scalar function Φ such that = Φ.
Thanks for the update. "Irrotational" means curl = zero, so we compute the curl, set it equal to zero, and solve for the constants.
[tex]\vec f(x,y,z) = (axy+z^3) \, \vec\imath + (3x^2-z) \, \vec\jmath + (bz^2-y) \, \vec k[/tex]
[tex]\nabla \times \vec f(x,y,z) = \left(\dfrac{\partial(bz^2-y)}{\partial y} - \dfrac{\partial(3x^2-z)}{\partial z}\right) \, \vec\imath - \left(\dfrac{\partial(bz^2-y)}{\partial x} - \dfrac{\partial(axy+z^3)}{\partial z}\right) \, \vec\jmath \\ ~~~~~~~~~~~~ + \left(\dfrac{\partial(3x^2-z)}{\partial x} - \dfrac{\partial(axy+z^3)}{\partial y}\right) \, \vec k[/tex]
[tex]\nabla \times \vec f(x,y,z) = 3z^2 \, \vec\jmath + (6-a)x \, \vec k[/tex]
At this point, all we can conclude is that a = 6 to make the k-component vanish. Unfortunately there's no zeroing out the j-component, so the field as given is *not* irrotational.
As I mentioned in comments, if the i-component had instead been [tex]axy+bz^3[/tex], we would have ended up with
[tex]\nabla \times \vec f(x,y,z) = 3bz^2 \, \vec\jmath + (6-a)x \, \vec k[/tex]
in which case we would have b = 0.
I'll continue working with this "fixed" field to find Φ, if only to give you an idea of how to proceed. We want a scalar function Φ(x, y, z) such that the given vector field is the gradient of f. This would entail solving the partial differential equations,
[tex]\dfrac{\partial\Phi}{\partial x} = axy+bz^3 = 6xy[/tex]
[tex]\dfrac{\partial\Phi}{\partial y} = 3x^2 - z[/tex]
[tex]\dfrac{\partial\Phi}{\partial z} = bz^2-y = -y[/tex]
Let's start with the last equation. Integrating both sides with respect to z yields
[tex]\Phi(x,y,z) = \displaystyle \int (-y) \, dz = -yz + g(x,y)[/tex]
Now differentiate both sides with respect to y :
[tex]\dfrac{\partial\Phi}{\partial y} = -z + \dfrac{\partial g}{\partial y} = 3x^2 - z \implies \dfrac{\partial g}{\partial y} = 3x^2[/tex]
Integrate both sides of the latter PDE with respect to y to solve for g :
[tex]g(x,y) = \displaystyle \int 3x^2 \, dy = 3x^2y + h(x)[/tex]
Now we differentiate Φ with respect to x :
[tex]\Phi(x,y,z) = -yz + 3x^2y + h(x) \\\\ \dfrac{\partial\Phi}{\partial x} = 6xy + \dfrac{dh}{dx} = 6xy \implies \dfrac{dh}{dx} = 0[/tex]
Integrate to solve for h :
[tex]h(x) = \displaystyle \int 0 \, dx = C[/tex]
where C is an arbitrary constant.
So the scalar function whose gradient is our "fixed" field f is
[tex]\Phi(x,y,z) = -yz + 3x^2y + C[/tex]

The value that would be obtained using the 5 midpoint rectangles of equal width to estimate the given Integral is; 33/100
How to partition integral?First of all, let us partition the interval [0, 1] as;
[0, 1/5] ∪ [1/5, 2/5] ∪ [2/5, 3/5] ∪ [3/5, 4/5] ∪ [4/5, 5]
Thus, the midpoints of the intervals which are the sample points are, respectively;
1/10, 3/10, 1/2, 7/10, 9/10
The integral is approximated by;
(0,1)∫x² dx = (5, n=1)Σf(x_n) Δx
where Δx is the difference between the partition endpoints, i.e.
Δx = (1 - 0)/5 = 1/5
and x_n is the midpoint of the nth partition.
Thus, we have;
(5, n=1)Σf(x_n) Δx = (1/5)[(1/10)² + (3/10)² + (1/2)² + (7/10)² + (9/10)²] = 33/100

a)Matthew noticed that the container was one fourth full of sand. How many more cubic inches of sand would be required to fill the container ? Show your work.
b) Matthew's father has a container that has dimensions that are each double the dimensions of Mathew's container.Matthew thought that the volume would be also double. Is Matthews correct? How many times greater is the volume of the larger container the the volume of the smaller one? Show your work and explain the reasoning. Can someone help ? thanks
When Matthew noticed that the container was one fourth full of sand, the remaining volume quantity needed is 432 inches³.
How to calculate the volume?The container has the following dimensions. 12 in. by 8in. by 6in. Therefore, the volume will be:
= 12 × 8 × 6
= 576 inches.
Since Matthew noticed that the container was one fourth full of sand, the remaining quantity needed will be:
= 576 - (1/4 × 576)
= 576 - 144
= 432 inches³.

Step-by-step explanation:
the side lengths of the base (the ground triangle) are equal. that means every ground side length is 8 in.
and that also makes the 3 triangles of the side areas of the pyramid equal.
so, for the surface area of the pyramid we need to calculate the area of one side area triangle, multiply it by 3 (as we have 3 side areas) and add the area of the ground triangle.
the area of a triangle is
baseline × height / 2
so, for a side area triangle we get
8 × 14 / 2 = 8×7 = 56 in²
all 3 side areas together are then
3×56 = 168 in²
the ground area triangle is then
8 × 6.9 / 2 = 4 × 6.9 = 27.6 in²
so, the total surface area of the pyramid is
168 + 27.6 = 195.6 in²
