Lena is asked to write an explicit formula for the graphed geometric sequence. On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 2. 5), (3, 6. 25). What value, written as a decimal, should Lena use as the common ratio? 1. 0 1. 5 2. 5 2. 0.
Answer:
r = 2.5
Step-by-step explanation:
Consider the y- coordinates of the plotted points
1 , 2.5 , 6.25
The common ratio r is calculated as
r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{a_{3} }{a_{2} }[/tex] = [tex]\frac{2.5}{1}[/tex] = [tex]\frac{6.25}{2.5}[/tex] = 2.5

Sam buys one bag of flour for $2.50, three packages of shredded cheese for $3.00 each, and n. packages of mushrooms for $3.50 each. If Sam paid $18.50 in all, how many packages of mushrooms did Sam buy?
Answer:
16.50
Step-by-step explanation:
2.50 + 3(3) + 2(3.50) = 2.50 + 9 + 5 = 16.50
Answer:
2
Step-by-step explanation:
One thing on flour costs $2.50
Three things of shredded cheese costs $9.00
$9.00 + $2.50=11.50
$18.50-11.50=$7.00
$7.00/$3.50=(2)
5, k+3, 2k+1 ,3k-2, 26 and 31 are in ascending order. if the median is 17. find the value of k.
Answer:
k = 7
Step-by-step explanation:
The median is the middle value of the data arranged in ascending order.
If there is no exact middle value then the median is the average of the 2 values either side of the middle.
5 , k + 3 , 2k + 1 , 3k - 2 , 26 , 31
↑ middle
Then
[tex]\frac{2k+1+3k-2}{2}[/tex] = 17 ( multiply both sides by 2 to clear the fraction )
5k - 1 = 34 ( add 1 to both sides )
5k = 35 ( divide both sides by 5 )
k = 7
The value of k is 7 if 5, k+3, 2k+1,3k-2, 26, and 31 are in ascending order and the median of the data set is 17.
What is the median?A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.
We have:
5, k+3, 2k+1 ,3k-2, 26 and 31 are in ascending order
The median of the data set is 17.
The mid-terms are 2k+1 ,3k-2
(2k + 1 + 3k - 2)/2 = 17
5k -1 = 34
5k = 34 + 1
5k = 35
k = 35/5
k = 7
Thus, the value of k is 7 if 5, k+3, 2k+1,3k-2, 26, and 31 are in ascending order and the median of the data set is 17.

Write the equation of each line in slope intercept form.
Step-by-step explanation:
Formulas and Formats we'll be using:
Slope Formula: [tex]m=\frac{y2}{x2} -\frac{y1}{x1}[/tex]
Slope-Intercept form: [tex]y=mx+b[/tex]
m = slope
b = y-intercept
Substitute (-6, 10) and (-3, -2) into the slope formula:
[tex]m=\frac{-2}{-3} -\frac{10}{-6}[/tex]
Simplify:
[tex]m=\frac{-12 \div 3}{3 \div 3}=\frac{-4}{1}[/tex]
[tex]m=-4[/tex]
*Per every -4 y, x increases by 1.
Points Included:
(-6, 10)
(-5, 6)
(-4, 2)
(-3, -2)
(-2, -6)
(-1, -10)
(0, -14)
Y-intercept:
Y-intercept represents x when it's equal to 0.
Using our points, we can determine that the y-intercept is at the point:
(0, -14)
-14 is the y-intercept.
Create a Slope-intercept form equation:
Formula: [tex]y = mx + b[/tex]
Substitute the slope, and y-intercept into the equation:
[tex]y=-4x-14[/tex]
Your equation is: [tex]y=-4x-14[/tex]

A person has a bag containing quarters and dimes. There are a total of 72 coins in the bag, and the total value of the coins is $13.20. Determine how many quarters and dimes are in the bag.
Answer:
40 quarters and 32 dimesStep-by-step explanation:
Given:
Quarter = 25 ¢, number of quarters = qDime = 10 ¢, number of dimes = dTotal amount = $13.20 = 1320 ¢Required equations:
q + d = 7225q + 10d = 1320Solve by elimination, multiply the first equation by 10 and subtract from the second equation:
25q + 10d - 10q - 10d = 1320 - 10*7215q = 600q = 600/15q = 40Find p:
40 + p = 72p = 72 - 40p = 32Let's take the given as,
→ q = quarters (25)
→ d = dimes (10)
→ 1320 will be the amount
→ q + d = 72
→ 25q + 10d = 1320
Now we can solve for q,
→ (25q - 10q) + (10d - 10d) = 1320 - (10 × 72)
→ 15q = 1320 - 720
→ 15q = 600
→ q = 600/15
→ [ q = 40 ]
From this equation,
→ q + d = 72
We can solve for the d,
→ 40 + d = 72
→ d = 72 - 40
→ [ d = 32 ]
There are 40 quarters & 32 dimes.

We have a right triangle $\triangle ABC$ where the legs $AB$ and $BC$ have lengths $6$ and $3\sqrt{3},$ respectively. Medians $AM$ and $CN$ meet at point $P.$ What is the length of $CP$
By using Pythagoras theorem and distance formula the length of CP is obtained as 3.43 units.
What is Pythagoras Theorem?
In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem. These triangle's three sides are known as the Perpendicular, Base, and Hypotenuse. Due to its position opposite the 90° angle, the hypotenuse in this case is the longest side.
To find the length of CP, first find the coordinates of point P, and then use the distance formula to calculate the length of CP.
Let A be at the origin (0, 0), and let B be on the positive x-axis at (6, 0). Then we can find the coordinates of C using the Pythagorean theorem -
AC² + BC² = AB²
AC² + (3√3)² = 6²
AC² = 9
AC = 3
So C is located at (3, 3√3). We can find the coordinates of M by taking the average of the coordinates of A and B, which gives -
M = ((0+6)/2, (0+0)/2) = (3, 0)
Similarly, find the coordinates of N by taking the average of the coordinates of B and C, which gives -
N = ((6+3)/2, (0+3√3)/2) = (4.5, 1.5√3)
Now find the equation of the line passing through M and C, which is the line containing median AM -
slope = (3√3 - 0)/(3 - 0) = √3
y - 0 = √3(x - 3)
y = √3x - 3√3
And find the equation of the line passing through N and A, which is the line containing median CN -
slope = (0 - 3√3)/(0 - 6) = √3/2
y - 0 = (√3/2)(x - 6)
y = (√3/2)x - 3√3
Now, find the intersection point of these two lines, which is point P -
√3x - 3√3 = (√3/2)x - 3√3
x = 6/3.5
x = 12/7
y = √3(12/7) - 3√3
y = 3√3/7
So P is located at (12/7, 3√3/7).
Now use the distance formula to find the length of CP:
CP² = (12/7 - 3)^2 + (3√3/7 - 3√3)²
CP² = (33/7)^2 + (6√3/7)^2
CP² = 1089/49 + 72/49
CP² = 1161/49
CP = √1161/7
Therefore, the length of CP is (approximately) 3.43.
