The table shows the height of a plant as it grows.
a. Model the data with an equation.
b. Based on your model, predict the height of the plant at 12 months
Answers
slope = (15 - 9) / (5 - 3) = 6/2 = 3
y = mx + b
slope(m) = 3
(3,9)...x = 3 and y = 9
sub and find b, the y int
9 = 3(3) + b
9 = 9 + b
9 - 9 = b
0 = b
so ur equation is : y = 3x + 0....can be written as y = 3x.
after 12 months...
y = 3x...x = 12
y = 3(12)
y = 36 inches

What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
James= 10 pieces of ribbon
Each of length= 2.1 feet
So, length of 10 ribbons
=2.1*10
=21 feet
Now, 1 yard= 3 feet

PEMDAS: When we look at PEMDAS we see parenthesis are first
So 2+3 equals 5.
Lets look at PEMDAS again, we see the next step is exponents so the 5 would need to be multiplied since it has no symbol and is next to the parenthesis.
Now we need to multiply what we got from 2+3 (which is 5) and the five that needs to be multiplied.

find the solution of the system of equations 2x-4y=32 2x-8y=48
Answers
2x-8y=48
--------------subtract
4y = - 16
y = -4
2x-4y=32
2x- 4(-4)=32
2x + 16 = 32
2x = 16
x = 8
answer
(8, -4)
2x - 8y = 48
Multiple equation 2 by -1 so the 'x' variables will cancel.
-1(2x - 4y = 32)
-2x + 4y = - 32
2x - 8y = 48
-------------------- add
- 4y = 16 divide both sides by -4
y = -4
Plug -4 back into either equation and solve for y.
2x - 4y = 32
2x -4(-4) = 32
2x + 16 = 32 subtract 16 from both sides
2x = 16 divide both sides by 2
x = 8

What are the x- and y- coordinates of point E, which partitions the directed line segment from J to K into a ratio of 1:4?
Answers
To solve this problem, we are given the formulas for our new x and y. To use this formula, we must first establish our points 1 and 2. Since the problem specifically directed the point E which partitions the line segment “from J to K”, therefore
point 1 = point J = (x1, y1)
point 2 = point K = (x2, y2)
The variables m and n indicates the portion of partition segment JE and EK that takes up from the original segment. Since the ratio is 1:4, then:
JE = m = 1
EK = n = 4
Therefore calculating for x and y using the given formulas:
x = [1 / (1 + 4)] (25 – (-15)) + (-15)
x = -7
y = [1 / (1 + 4)] (15 – (-5)) + (-5)
y = -1
Therefore the coordinates of point E is (-7, -1)
The x- and y- coordinates of point E (-7,-1)
Further explanationIn the coordinates of the two-dimensional plane (xy) there is a position vector.
Two dimensions because the coordinates are only x and y, three dimensions if the coordinates are x, y, and z.
If there is a point P then
You can write P as:
P = xi + yi
where i denotes the unit vector in the x and y directions
While the size of the vector:
[tex]\displaystyle P = \sqrt{x^2+y^2}[/tex]
and its direction
[tex]\displaystyle \theta=arc\:tan\:\frac{y}{x}[/tex]
If a point C divides the line segment AB by the ratio m: n, then the coordinates of point C can be formulated:
[tex]\displaystyle \vec{C}=\frac{m\vec{b}+n\vec{a}}{m+n}[/tex]
Coordinate x :
[tex]\displaystyle x=\frac{m.x_2+n.x_1}{m+n}[/tex]
Coordinate y :
[tex]\displaystyle y=\frac{m.y_2+n.y_1}{m+n}[/tex]
line segment from J to K into a ratio of 1:4, then m = 1 and n = 4
(x1,y1) from point J= (-15,-5)
(x2,y2) from point K= (25,15)
So coordinates of point E :
Coordinate x :
[tex]\displaystyle x=\frac{1.25+4.-15}{5}[/tex]
x = -7
Coordinate y :
[tex]\displaystyle y=\frac{1.15+4.-5}{5}[/tex]
y = -1

What is the value of x in this equation: 4x + 5 = 3x + 4? Solve the equation using the algebra tiles. x =
Answers
Answer:
Solution of the equation 4x + 5 = 3x + 4 is:
x= -1
Step-by-step explanation:
We are given a equation:
4x + 5 = 3x + 4
We have to solve the equation for x
4x+5=3x+4
subtracting both sides by 4
4x+5-4=3x+4-4
4x+1=3x
subtracting both sides by 4x
4x|+1-4x=3x-4x
1= -x
⇒ x= -1
Hence, solution of the equation 4x + 5 = 3x + 4 is:
x= -1
The sum of the interior angles of a polygon is 9900degrees how many sides does the ploygon have?
Answers
There are 57 sides does the polygon have.
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
The sum of the interior angles of a polygon is,
⇒ 9900 degrees
Since, We know that;
The formula is,
⇒ (n - 2) × 180
Hence, We get;
⇒ 9900 = (n - 2) × 180
⇒ n - 2 = 9900 / 180
⇒ n - 2 = 55
⇒ n = 55 + 2
⇒ n = 57
Thus, There are 57 sides does the polygon have.

find the volume of the shaded solid. Round your answer to 2 decimal places if necessary. Use pi=3.14 when necessary. cylinder with these 6ft, 18ft, 30 ft.
Answers
The volume of any cylinder is the area of the top circle (pi×r^2) times the height (h) of the cylinder, where r=radius of the circle. So: h×pi×r^2
The heights are the same for C and c, so we can call that h in both, which = 30ft. Now C's radius (R) = 1/2 of diameter, which is 18ft. So R = 9ft
c's radius (r) is 1/2 of its diameter, which is 6ft. So r = 3ft. Now we can set it up:
C - c = (h×pi×R^2) - (h×pi×r^2)
*since the h and pi in both formulae are multiplied by the other variable, we can factor that out:
h×pi(R^2) - h×pi(r^2) = h×pi(R^2-r^2)
h×pi = 30ft.×3.14 = 94.2ft. -->
94.2ft(9ft^2-3ft^2) = 94.2ft(81-9ft^2)
= 94.2ft(72ft^2) = 6782.4 ft.^3

Find the sum of this infinite geometric series where a1=0.3 and r=0.55
Answers
We know that in a geometric sequence defined by [tex]\mathsf{a_1}[/tex] and [tex]\mathsf{r}[/tex] , the sum can be calculated the following way:
[tex]\mathsf{S_n = \dfrac{a_1}{1-r}}\\ \\ \\ \\ \mathsf{S_n = \dfrac{0.3}{1-0.55}}\\ \\ \\ \mathsf{S_n = \dfrac{0.3}{0.45}}\\ \\ \\ \boxed{\mathsf{S_n = \dfrac{2}{3}=0.666...}}[/tex]
Answer:
The sum of the infinite geometric sequence is given by:
[tex]S_{\infty} = \frac{a_1}{1-r}[/tex] ....[1]
where,
[tex]a_1[/tex] is the first term
r is the common ratio.
As per the statement:
Given that [tex]a_1 = 0.3[/tex] and r = 0.55
To find the sum of this infinite geometric series.
Substitute the given values in [1] we have;
[tex]S_{\infty} = \frac{0.3}{1-0.55}[/tex]
⇒[tex]S_{\infty} = \frac{0.3}{0.45}[/tex]
Simplify:
[tex]S_{\infty} \approx 0.67[/tex]
