Just as a plane figure can have mirror lines of symmetry, so can a solid have mirror planes of symmetry dividing it into mirror-image halves. Thus, a cuboid has three planes of symmetry dividing it into two halves.

The Blue Shell's flight path is modeled by the equation:
y = -10x2 + 100x + 750
a) Fill in the table below. The points will be used to plot on the below graph to create a
parabola.
b) Based on the table, what is the maximum
Y у
height the blue shell reaches?
Answer:
1. I assume you just pick some arbitrary x and y numbers to plug in the equation. but if you answer part b and c first, part a might be easier for what values to choose.
2. if you do a quick browser search for how to find the max height of a parabola, then you can learn how to.
3. research on Browser. you can also just make y = 0.
vertex is max height, both zeros is just solving the equation for the x values. axis of symmetry is just the vertex point with a line through it.
Write the an equation of a line that is perpendicular to y= 1/3x + 5 and intersects it at the y intercept
Answer:
y = -3x + 5
Step-by-step explanation:
For two lines to be perpendicular, the product of their slope must be -1.
Slope of the given line M = 1/3
Slope of the required line is m
If product is -1, then;
Mm = -1
1/3 m = -1
m = -3
SInce it intersects at the y intercept, y intercept c = 5
Get the required equation. Substitute m = -3 and c = 5 into the equation
y = mx+c
y = -3x + 5
Hence the required equation of the line is y = -3x + 5
3 (2x+8) = 60 x=____
Answer:
x=4/9
Step-by-step explanation:
3(2x+8)=60x
6x+24=60x
6x+24-24=60x-24 -60x
-54x=-24
-54x= -24
x= 4/9

2x - 3y = 1
3x + y=-5
Solve geographically
Answer:
1) x=3/2y+1/2
2)x=-1/3y+-5/3
Step-by-step explanation:
1)
Let's solve for x.
2x−3y=1
Step 1: Add 3y to both sides.
102x−3y+3y=1+3y
2x=3y+1
Step 2: Divide both sides by 2.
2x/2
=
3y+1/2
x=3/2y+1/2

what is the common ratio of the geometric sequence below? –2, 4, –8, 16, –32, ...
Answer:
The common ratio of the geometric sequence is:
[tex]r=-2[/tex]
Step-by-step explanation:
A geometric sequence has a constant ratio 'r' and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
where
aₙ is the nth terma₁ is the first termr is the common ratioGiven the sequence
[tex]-2,\:4,-8,\:16,\:-32,\:...[/tex]
Compute the ratios of all the adjacent terms: [tex]r=\frac{a_n+1}{a_n}[/tex]
[tex]\frac{4}{-2}=-2,\:\quad \frac{-8}{4}=-2,\:\quad \frac{16}{-8}=-2,\:\quad \frac{-32}{16}=-2[/tex]
The ratio of all the adjacent terms is the same and equal to
[tex]r=-2[/tex]
Therefore, the common ratio of the geometric sequence is:
[tex]r=-2[/tex]solve the equation 3m - 7 = 8

Answer:
m=5
Step-by-step explanation:
3(5)=15
therefore,
15-7=8
<3
Answer:
Add 7 to both sides of the equation
3 − 7 + 7 = 8 + 7
Simplify
3m = 8 + 7
3 = 1 5
Divide both sides of the equation by the same term
3 = 1 5
3 / 3 = 1 5 /3
The answer
= 5

Solve the simultaneous equations
2x + 4y = 1
3x - 5y = 7
y=1.5 x=
What does x equal
Answer:
The solution to the system of equations be:
x = 0.5, y = -0.5
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}2x+4y=1\\ 3x-5y=7\end{bmatrix}[/tex]
Multiply 2x+4y=1 by 3: 6x+12y=3
Multiply 3x-5y=7 by 2: 6x-10y=14
[tex]\begin{bmatrix}6x+12y=3\\ 6x-10y=14\end{bmatrix}[/tex]
subtracting the equations
[tex]6x-10y=14[/tex]
[tex]-[/tex]
[tex]\underline{6x+12y=3}[/tex]
[tex]-22y=11[/tex]
solve -22y for y
[tex]-22y=11[/tex]
Divide both sides by -22
[tex]\frac{-22y}{-22}=\frac{11}{-22}[/tex]
Simplify
[tex]y=-\frac{1}{2}[/tex]
[tex]y = -0.5[/tex]
For 6x+12y=3 plug in y = -1/2
[tex]6x+12\left(-\frac{1}{2}\right)=3[/tex]
[tex]6x-12\cdot \frac{1}{2}=3[/tex]
[tex]6x-6=3[/tex]
Add 6 to both sides
[tex]6x-6+6=3+6[/tex]
[tex]\frac{6x}{6}=\frac{9}{6}[/tex]
Simplification
[tex]x=\frac{3}{2}[/tex]
[tex]x = 1.5[/tex]
Therefore, the solution to the system of equations be:
x = 0.5, y = -0.5

Which graph represents the solution to the compound inequality?
–6 < 3x – 12 ≤ 9
Answer:
second graph
Step-by-step explanation:
Solving the inequality
- 6 < 3x - 12 ≤ 9 ( add 12 to all 3 intervals )
6 < 3x ≤ 21 ( divide the intervals by 3 )
2 < x ≤ 7
The graph has an open circle at 2 and a closed circle at 7
This is represented on the second graph
