Step-by-step explanation:
1. Given the length, width and tallness discover the volume, surface region and inclining of a rectangular crystal
h, l and w are known; discover V, S and d
V = lwh
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
2. Given the surface region, length and width discover the tallness, volume and askew of a rectangular crystal
S, l and w are known; discover h, V and d
h = (S - 2lw)/(2l + 2w)
V = lwh
d = √(l2 + w2 + h2)
3. Given the volume, length and width discover the stature, surface territory, and slanting of a rectangular crystal
V, l and w are known; discover h, S and d
h = V/lw
S = 2(lw + lh + wh)
d = √(l2 + w2 + h2)
4. Given the inclining, length and width discover the tallness, volume and surface space of a rectangular crystal
d, l and w are known; discover h, V and S
h = √(d2 - l2 - w2)
V = lwh
S = 2(lw + lh + wh)

Angel b=angle a+angle c-180
We have now proven that all three angles of ΔABC have a measure of 60 degrees. Therfore, ∠C must have a measure of 60 degrees
Answer:
x = -15, angle b = 115, angle c = 30.
Step-by-step explanation:
The 3 sides of a triangle add up to 180, so the equation will be
35 - 5 - 8x - 2x = 180
30 - 10x = 180
Subtract 30 from both sides.
-10x = 150
Divide by -10.
x = -15.
Finding angle b:
-5 - 8x
-5 - 8(-15)
-5 + 120
115
Finding angle c:
-2x
-2(-15)
30
To check it, we add angle a, angle b, and angle c together.
35 + 115 + 30
150 + 30
180.
Quinton just read that his new computer, which costs
$2,500, loses 10% of its value every year. Which function
can be used to determine the value of his computer after
x years?
A f(x) = 2,500(.10)*
Cf(x) = 10(2,500)*
B f() = 2,500(1.1)*
D f(x) = 2,500(.90)*
Answer:
x/2500=10/100
Step-by-step explanation:
The value of the computer after 10 years is represented by the function [tex]f(x) = 2500(0.9)^n[/tex]. The correct option is D.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Answer:
Part A
1. After 4 weeks of work, Jeremy has saved 300
2. Jeremy worked 8 weeks in order to save $600
3. For every one week of work, Jeremy saved 75 dollars
4. If Jeremy works 15 weeks, then he can expect to save 1,125 dollars
Part B
1. Saeed orders 15 meals and his total cost of delivery is $24
2. Saeed paid $32 to have 20 meals delivered
3. For every meal delivered, Saeed is charged $1.6
4. If Saeed pays $19.20 in delivery fees then he ordered 12 meals
Step-by-step explanation:
Part A
The given graph gives the proportional relationship between total amount saved and the number of weeks worked
1. Reading from the graph, at the point where the vertical line from point 4 touches the line of the graph, an horizontal line to the vertical y-axis touches the y-axis at 300
Therefore;
After 4 weeks of work, Jeremy has saved 300
2. The point where an horizontal line from point 600 on the vertical y-axis touches the line of the graph, a vertical line drawn to the horizontal, x-axis touches the x-axis at 8
Therefore;
Jeremy worked 8 weeks in order to save $600.
3. The rate of change of the amount saved to the number of weeks worked, 'm', for the given proportional relationship (straight line relationship, passing through the origin) is given as follows;
Rate of change, m = Constant = y/x
∴ Rate of change of the amount saved to the number of weeks worked = (300-0)/(4 weeks- 0 week) = 75/week
Therefore;
For every one week of work, Jeremy saved 75 dollars
4. The amount Jeremy would have saved in 15 weeks, 'A', is given as follows;
A = m × n
Where;
m = The rate of change of the amount saved to the number of weeks worked = 75/week
n = The number of weeks worked
∴ A = 75/week × 15 = $1,125
Therefore;
If Jeremy works 15 weeks, then he can expect to save 1,125 dollars
Part B
From the graph, we have;
1. From the graph there is a proportional relationship between the total cost of delivery and the number of meals
At the point a vertical line drawn to the line of the graph from 15 on the horizontal axis (number of meals), a horizontal line drawn to the vertical y-axis touches the y-axis at 24
Therefore;
1. Saeed orders 15 meals and his total cost of delivery is $24
2. From the point where the horizontal line from 32 on the vertical axis touches the linear graph of the relationship between the total cost of delivery and the number of meals, a vertical line drawn down to the horizonal axis touches the horizontal x-axis at 20
Therefore;
Saeed paid $32 to have 20 meals delivered
3. The rate of change of the total cost of delivery to the number of meals, 'm', is given as follows;
m = y/x (for proportional relationships)
Taking any corresponding 'x' and y-values
m = 16/10 = 32/20 = 24/15 = 1.6 Dollars/meal
Therefore;
For every meal delivered, Saeed is charged $1.6
4. From m = y/x = 1.6
When y = $19.20
x = y/m = $19.20/($1.6/meal) = 12 meals
Therefore;
If Saeed pays $19.20 in delivery fees then he ordered 12 meals.
Find the slope of the line graphed below.
Given:
The graph of a line.
To find:
The slope of the graphed line.
Solution:
From the given graph it is clear that the line passes through the points (-2,2) and (2,5). So, the slope of the line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{5-2}{2-(-2)}[/tex]
[tex]m=\dfrac{3}{2+2}[/tex]
[tex]m=\dfrac{3}{4}[/tex]
Therefore, the slope of the given graphed line is [tex]m=\dfrac{3}{4}[/tex].

Hello!
This is a question about multiplying to get a polynomial answer.
Here we can use two strategies, which will get you the same strategy.
One is using a Punnett Square, and the other would be FOILing.
I personally like Punnett Squares, but I will use FOILing for the sake of being online.
FOIL stands for First, Outside, Inside, Last, which describes how the terms should be multiplied.
Let's multiply the first terms.
(-d + e)(4e + d)
[tex]-4de[/tex]
The outside terms.
(-d + e)(4e + d)
[tex]-d^2[/tex]
The inside terms.
(-d + e)(4e + d)
[tex]4e^2[/tex]
The last terms.
(-d + e)(4e + d)
[tex]de[/tex]
Now you just add them together to find the polynomial.
[tex]-d^2+4e^2-4de+de[/tex]
[tex]-d^2+4e^2-3de[/tex]
There are three terms in the product, and the product is degree 2, since the highest degree of the equation (the highest power any term is raised to) is 2.
Hope this helps!

Complete the following proof. Prove: In an isosceles triangle, two medians are equal.
Answer:
Midpoint of AB = (0 + 2a / 2 , 0 + 0 / 2) = (2a / 2 , 0 / 2) = (a,0)
x coordinate of point c = a
N = (0 + a / 2 , 0 + b / 2) = (a / 2 , b / 2)
M = ( 2a + a / 2 , 0 + b / 2) = (3a / 2 , b / 2)
MA = √(3a / 2 - 0)² + b / 2 - 0)²
= √(3a / 2 )² + (b / 2) = 9a² / 4 + b² / 4
NB = √(a / 2 - 2a)² + (b / 2 - 0 )²
= √( a / 2 - 4a / 2)² + (b / 2 - 0)²
= √(-3a / 2)² + (b / 2)² = √9a² / 4 + b² / 4

Answer:
JK = 8
Step-by-step explanation:
Given 2 intersecting chords, then
The product of the measures of the parts of one chord is equal to the product of the measures of the other chord, that is
x(x + 4) = (x + 1)(x + 2) ← expand parenthesis
x² + 4x = x² + 3x + 2 ( subtract x² + 3x from both sides )
x = 2
Then
JK = x + 4 + x = 2x + 4 = 2(2) + 4 = 4 + 4 = 8

Answer:
They played 4 games and paid $19
Step-by-step explanation:
4x + 3 = 2x + 11 (You basically have to solve for X)
4x - 2x = 11 - 3 (move like terms together)
2x = 8
x = (8/2)
x = 4
This means they had to play 4 games.
To get how much they paid, just plug 4 into any one of those given equations (They will both give the same answer).
4x + 3 ⇒ 4(4) + 3 = $19
To check if this is true,
2x + 11 ⇒ 2(4) + 11 = $19
Therefore, they paid $19
Answer:
$19 and played 4 games

Given:
The equation of a circle is:
[tex](x-3)^2+y^2=32[/tex]
To find:
Center and the circumference of the circle.
Solution:
The standard form of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex] ...(i)
Where, (h,k) is center and r is the radius.
We have,
[tex](x-3)^2+y^2=32[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]h=3,y=0,r=\sqrt{32}[/tex]
So, the center of the circle is (3,0) and the radius of the circle is [tex]\sqrt{32}[/tex].
Now, the circumference of the circle is:
[tex]C=2\pi r[/tex]
[tex]C=2(3.14)(\sqrt{32})[/tex]
[tex]C=35.525045[/tex]
[tex]C\approx 35.5[/tex]
Therefore, the circumference of the circle is about 35.5 units.

A helicopter flies 665 feet above ground. What is the measure of the angle of depression fro t the helicopter to the girls line of sight
Answer:
67°
Step-by-step explanation:
CHECK THE ATTACHMENT FOR THE FIQURE
From, trigonometry
tan(θ) = opposite/ adjacent
✓The helicopter is 665 feet from ground.
✓Distance of the helicopter and the line of sight of the girl will be the OPPOSITE SIDE, which is
(665ft - 5 ft)
= 600 ft
✓ from the figure, we can see the distance on the Horizontal side which is the ADJACENT SIDE as ( 280 ft)
✓angle of depression can be calculated as
tan(θ) = opposite/ adjacent
tan(θ)= (660/280)
tan(θ)= 2.357
tan-1=(2.357)
θ= 67°
Hence, angle of depression is 67°
