Is it possible to construct a cube with 2000
interlocking cubes? Justify your answer.
It is possible to construct a cube with 2000
interlocking cubes depending on the sides for each.
How to illustrate the information?It should be noted that a cube had 6 equal faces. In this case, a cube with 2000 interlocking faces can't be constructed with equal number of faces.
In this case, the sides will be:
= 2000 / 6
= 333.33
In this case, it should be noted each side will be 333.33.
Also, if you want each to be a whole number, this won't be possible.

2(b + 5) = 3(b - 2) + 23
Answer:
b = -7
Step-by-step explanation:
2(b + 5) = 3(b - 2) + 23
2b + 10 = 3b - 6 + 23
10 + 6 -23 = 3b - 2b
-7 = b
Answer:
b = -7
Step-by-step explanation:
[tex]2(b+5) = 3(b-2) + 23[/tex]
for the left side of the equation: [tex]2*b + 2*5 = 2b + 10[/tex]
for the right side of the equation: [tex]3*b + 3*-2 = 3b - 6 + 23 = 3b + 17[/tex]
[tex]2b + 10 = 3b + 17[/tex]
to isolate b, subtract 2b from both sides
[tex]10 = b + 17[/tex]
subtract 17 from both sides
[tex]-7 = b\\b = -7[/tex]

Find an equation of the tangent line to the curve xey yex = 4 at the point (0, 4).
An equation of the tangent line to the curve [tex]x e^y+y e^x=4[/tex] at the point (0, 4) is [tex]y=-(4+e^4) x+4[/tex].
What is tangent?A tangent is described as a line that intersects a circle or an ellipse only at one point. If a line touches a curve at P, the point "P" is known as the point of tangency.
Now according to the question;
To obtain the tangent at a given point, we must first obtain the slope at that point by obtaining the differentiation value at that point [tex]\left.y^{\prime}\right|_{x=0, y=4}[/tex] as-
Consider the given equation;
[tex]x e^y+y e^x=4[/tex]
Differentiate both side with respect to x;
[tex]\begin{aligned}&\frac{d}{d x}\left(x e^y+y e^x\right)=\frac{d}{d x} 4 \\&\frac{d}{d x} x e^y+\frac{d}{d x} y e^x=0\end{aligned}[/tex]
Now apply product rule;
[tex]\begin{aligned}&e^y \frac{d}{d x} x+x \frac{d}{d x} e^y+e^x \frac{d}{d x} y+y \frac{d}{d x} e^x=0 \\&e^y \frac{d}{d x} x+x \frac{d}{d y} e^y \cdot y^{\prime}+e^x y^{\prime}+y \frac{d}{d x} e^x=0\end{aligned}[/tex]
Applying exponential and power rule;
[tex]\begin{aligned}&e^y \cdot 1+x e^y \cdot y^{\prime}+e^x y^{\prime}+y e^x=0 \\&\left(x e^y+e^x\right) y^{\prime}=-y e^x-e^y\end{aligned}[/tex]
Solve the value of y'
[tex]y^{\prime}=\frac{-y e^x-e^y}{x e^y+e^x}[/tex]
Now, find the value of slope m.
[tex]m=\left.y^{\prime}\right|_{x=0, y=4}[/tex]
[tex]\frac{-4 \cdot e^0-e^4}{0 e^4+e^0}=-4-e^4[/tex]
Now, using the point-slope formula, obtain the line equation as follows.
[tex]\begin{aligned}&\left(y-y_1\right)=m\left(x-x_1\right) \\&(y-4)=-(4+e^4) \cdot(x-0) \\&y=-(4+e^4) x+4\end{aligned}[/tex]
Therefore, an equation of the tangent line to the curve is [tex]y=-(4+e^4) x+4[/tex].

Create the equation that could show the missing step.
The equation which could show the missing step in Tyler's solution to the equation as requested in the task content is; 10x + 8x = 36.
What is the solution that could show the missing step in Tyler's solution to the equation as requested in the task content?It follows from the task content that the missing step in the solution steps is to be determined.
Given an equation;
10x = -4(2x-9)

10x = -8x + 36
The next step which is therefore the missing step is;
Add 8x to both sides of the equation so that we have;
10x + 8x = 36
18x = 36
Divide both sides by 18, so that we have;
x = 2 as obtained in the task content.
Ultimately, the equation which could show the missing step in Tyler's solution to the equation as requested in the task content is; 10x + 8x = 36.

Sales at LL Boutique decreased 10% this month compared to last month. If sales this month were $157,581, what were the sales (in $) last month?
Answer:
173, 339.10
Step-by-step explanation:
Move the decimal from 157,581.00 to the left to give you 10% of 15,758.10.
Add 15,758.10 to 157,581.00 to give you the total from last month.
Or, convert 10% to a decimal.
157,781 x 0.10 = 15,758.10
15,758.10 + 157,581 = 173,339.10

dispersion, range and standard deviation mean, median and mode
Mean, median and mode are the three principles of describing data.
Describing data:- Describing data is also called descriptive statistics, that describes the data through several methods such as graphical representations, central tendency, variability. It summarizes the data efficiently, which helps to make any conclusion on that dataset.
The three principles of describing data are-
Mean:- The summation of all the values divided by the total number of values, is called mean. It is also called as average.Median:- The middle value is called median.Mode:- The value, which occurs most often in a set of all values, is called mode.Thus we can conclude that, mean, median and mode are the three principles of describing data.

Answer:
$20.1
Step-by-step explanation:

Step-by-step explanation:
Let s = the cost of a small package and
l = the cost of a large package
1 small pakcage and 5 large package
1s+5l
Substitute s = $2.60 and l = $3.50
1($2.60) + 5(3.50)

An executive invests 28,000 some at 7% and the rest at 4% annual interest if he receives an annual return of $1,570 how much is invested at each rate
we get that the amount invested at 7 % interest rate is $ 15,000 and at 4 % interest rate is $ 13,000.
We are given that:
the total amount invested is = $ 28,000
Let the amount invested at 7 % interest rate be x
Amount invested at 4 % interest rate = 28,000 - x
Interest received at the end of year = $ 1570
ATQ:
7 % x + 4 % ( 28,000 - x) = 1570
7 x + 4 (28,000 - x) = 157000
7 x + 112,000 - 4 x = 157,000
3 x = 157,000 - 112,000
3 x = 45,000
x = 45,000 / 3
x = 15,000
Amount invested at 7 % interest rate = x = $ 15,000
Amount invested at 4 % interest rate = 28,000 - x = $ 13,000
Therefore, we get that the amount invested at 7 % interest rate is $ 15,000 and at 4 % interest rate is $ 13,000.

What is the line of symmetry for the parabola whose equation is y=x²-12x + 7?
Ox=12
Ox=6
Ox=-6
Answer:
x = 6
Explanation:
completing square:
[tex]y=x^2-12x+7[/tex]
[tex]y=(x^2-12x)+7[/tex]
[tex]y=(x-6)^2+7-(-6)^2[/tex]
[tex]y=(x-6)^2+7-36[/tex]
[tex]y=(x-6)^2-29[/tex]
Comparing with quadratic equation [tex]y=ax^2 + bx+c[/tex], in vertex form where [tex]y = a(x-h)^2+k[/tex]. In this x - h = 0, x = h defines the symmetry of equation.
So here the symmetry for parabola:
x - 6 = 0
x = 6
Answer:
x = 6
Step-by-step explanation:
The axis of symmetry of a parabola is the x-value of its vertex.
For a quadratic function in the form [tex]y=ax^2+bx+c[/tex], the x-value of the vertex is:
[tex]x=-\dfrac{b}{2a}[/tex]
Given function:
[tex]y=x^2-12x+7[/tex]
Therefore:
[tex]a=1, \quad b=-12, \quad c=7[/tex]
So the axis of symmetry of the given quadratic function is:
[tex]\implies x=-\dfrac{b}{2a}=-\dfrac{-12}{2(1)}=\dfrac{12}{2}=6[/tex]
