2. (#6) The French club is sponsoring a bake sale to raise at least $305. How many pastries must they sell at $2.05 each in order to reach their goal?
The rule for the linear function that describes the length of the vine is L = 1.3 + 0.2d
The number of days it would take the vine to grow to be 10.3 inches long is 45 days
Linear functions
From the question, we are to determine a linear function that describes the situation
From the given information,
Then vine is 1.3 inches long now
and it grows 0.2 inches a day
∴ After the days, the vine will increase by 0.2d in length
Then,
If L represents the length of the vine, d represent the number of days
The length of the vine after d number of days will be
L = 1.3 + 0.2d
Hence, the rule for the linear function that describes the length of the vine is L = 1.3 + 0.2d
Now, we are to determining the number of days it will take the vine to grow to be 10.3 inches long
Using the above linear function
L = 1.3 + 0.2d
10.3 = 1.3 + 0.2d
0.2d = 10.3 - 1.3
0.2d = 9
d = 9 / 0.2
d = 45
Hence, the number of days it would take the vine to grow to be 10.3 inches long is 45 days

6/(x^2-3x)=12/x+1/(x-3) with full expanation from the internet
Answer:
[tex]x=\dfrac{42}{13}[/tex]
Step-by-step explanation:
Given equation:
[tex]\dfrac{6}{(x^2-3x)}=\dfrac{12}{x}+\dfrac{1}{(x-3)}[/tex]
Factor the denominator on the left side:
[tex]\implies \dfrac{6}{x(x-3)}=\dfrac{12}{x}+\dfrac{1}{(x-3)}[/tex]
Combine the fractions on the right side by multiplying by the LCM:
[tex]\begin{aligned}\implies \dfrac{6}{x(x-3)} & =\dfrac{12}{x} \cdot \dfrac{(x-3)}{(x-3)}+\dfrac{1}{(x-3)} \cdot \dfrac{x}{x}\\\\& =\dfrac{12(x-3)}{x(x-3)}+\dfrac{x}{x(x-3)}\\\\& =\dfrac{12(x-3)+x}{x(x-3)} \end{aligned}[/tex]
As the denominators are now the same on both sides:
[tex]\begin{aligned}\implies \dfrac{6}{x(x-3)} & =\dfrac{12(x-3)+x}{x(x-3)}\\\\ \implies 6 & = 12(x-3)+x\end{aligned}[/tex]
Simplify and solve for x:
[tex]\begin{aligned}\implies 6 & = 12(x-3)+x\\\\6 & =12x-36+x\\\\6 & =13x-36\\\\13x & =42\\\\\implies x & =\dfrac{42}{13}\end{aligned}[/tex]

A car purchased for $15,000 depreciates under a straight-line method in the
amount of $950 each year. Which equation below best models this
depreciation?
A. y = 15000x-950
OB. y = 15000 +950x
OC. y = 15000-950x
OD. y = 15000x+950
Answer:
i can't send full page of it sorry
The equation y = 15000 - 950x best models the depreciation.
Option C is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The equation y = 15000 - 950x.
Here, y represents the value of the car after x years.
The initial value of the car is $15,000, which means the value of the car at x = 0 is $15,000.
The car depreciates by $950 each year, so after one year, the value of the car will be $15,000 - $950 = $14,050.
After two years, the value of the car will be $14,050 - $950 = $13,100, and so on.
This linear relationship between the value of the car and the number of years can be modeled by the equation y = 15000 - 950x,
where 15000 is the initial value and -950x represents the amount of depreciation each year.
Thus,
The equation y = 15000 - 950x best models the depreciation.

Find the μ and o for the below data set. Is there an outlier?
15, 75, 88, 92, 100
The population mean (μ) is: 74
The standard deviation (σ) is: 30.6
There is an outlier, 15.
How to Find the Population Mean (μ) and the Standard Deviation (σ)?Population mean (μ) = sum of data points / number of data points
Standard deviation (σ) = √(sum of squares/number of data points) = √(SS/n)
Given the data, 15, 75, 88, 92, 100:
Population mean (μ) = (15 + 75 + 88 + 92 + 100)/5 = 74
Standard deviation (σ) = √(4678/5)
σ = √935.6
σ = 30.6

A lighthouse sits at the edge of a cliff, as shown. A ship at sea level is 980 meters from the base of the cliff. The angle of elevation from sea level to the base of the lighthouse is 47.3. The angle of elevation from sea level to the top of the lighthouse is 51.3. Find the height of the lighthouse from the top of the cliff.
Using the tangent ratio, the height of the lighthouse from the top of the cliff ≈ 161.2 meters.
What is the Tangent Ratio?For solving a right triangle, the tangent ratio that can be applied is: tan ∅ = opposite length / adjacent length.
Find the height of the light house and the cliff using the tangent ratio:
tan 51.3 = height/980
Height of lighthouse + cliff = (tan 51.3)(980)
Find the height of the cliff only using the tangent ratio:
tan 47.3 = height/980
Height of cliff = (tan 47.3)(980)
Height of the lighthouse from the top of the cliff = (tan 51.3)(980) - (tan 47.3)(980)
Height of the lighthouse from the top of the cliff ≈ 161.2 meters.

Can you help me with a question? What is the equation of the blue line?
Answer:
y = -x - 1
Step-by-step explanation:
y = mx + b
slope (m): Since the line is going downhill, the slope will be negative
slope = rise / run
slope = 1 / 1
slope = 1
m = -1
y - intercept (b): this when x = 0, the line is crossing the vertical line (y-axis)
b = -1
so y = mx + b is
b = -1, m = -1
y = (-1)x + (-1)
Answer:
y = - x - 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = [tex]\frac{-1-0}{0-(-1)}[/tex] = [tex]\frac{-1}{0+1}[/tex] = [tex]\frac{-1}{1}[/tex] = - 1
the line crosses the y- axis at (0, - 1 ) ⇒ c = - 1

The manager at a ice cream shop keeps track of the number of deluxe cones and regular cones sold each day and the total money received. On Wednesday, a total of 86 cones were sold, and the money collected was $534. If deluxe cones are sold for $9 and regular cones are sold for $5, how many deluxe cones and regular cones were sold?
Give your answer as an ordered pair (x,y), where x is the number of deluxe cones and y is the number of regular cones.
The number of regular cones sold on Wednesday is 60, while the number of deluxe ones sold is 26.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the number of regular cones sold be x, and the number of Deluxe cones sold be y. Therefore, total number of cones sold can be written as,
x + y = 86
x = 86 - y
Now, the total money collected can be written as,
5x + 9y = 534
5(86 - y) + 9y = 534
430 - 5y + 9y = 534
4y = 104
y = 26
substitute the value of y in the first equation,
x = 86 - 26
x = 60
Hence, the number of regular cones sold on Wednesday is 60, while the number of deluxe ones sold is 26.

Hey there!
Unless the smaller object was rotated 360° (in which case the rotation wouldn't have to be mentioned), you can see that all of the lines are still in the same place and that it wasn't rotated at all. This eliminated any answer option that mentions a rotation, which is A and C.
Also, if you count the units of one of the straight lines – for example, line AB and A'B' – you can see that the smaller object is four times smaller than the larger object. In the case of line AB and A'B', line AB is 8 units long and A'B' is 2 units long. This means that the scale factor is [tex]1[/tex].
Lastly, the smaller object was moved from its initial location, which would be in the center of the larger object if it wasn't moved after being scaled down.
The answer will be, "a dilation with a scale factor of [tex]1[/tex] and then a translation."

b) The probability that a Canadian woman's height will be larger than x cm is 1%.
Determine x, to the nearest centimeter.
The probability of having a height that is between 158 cm and 163 cm is 0.69011 and the value of x is 169 centimeters
The probability of having a height that is between 158 cm and 163 cmThe given parameters are:
Mean = 161Standard deviation = 6Calculate the z-scores at x = 158 and x = 163 using:
[tex]z = \frac{x - \mu}{\sigma}[/tex]
So, we have:
[tex]z = \frac{158 - 161}{6} = -0.5[/tex]
[tex]z = \frac{163 - 161}{6} = 0.33[/tex]
The probability is then represented as:
P(158 ≤ x ≤ 161) = P(-0.5 ≤ z ≤ 0.33)
Using the z table, we have:
P(158 ≤ x ≤ 161) = 0.69011
Hence, the probability of having a height that is between 158 cm and 163 cm is 0.69011
The value of x in the probabilityThe probability is represented as:
P(X ≥ x) = 1%
Express as decimal
P(X ≥ x) = 0.10
The z-score at p = 0.10 is:
z = 1.282
Substitute z = 1.282 in [tex]z = \frac{x - \mu}{\sigma}[/tex]
[tex]1.282 = \frac{x - \mu}{\sigma}[/tex]
Make x the subject
[tex]x = 1.282\sigma + \mu[/tex]
Substitute values for standard deviation and mean
x = 1.282 * 6 + 161
Evaluate
x = 168.692
Approximate
x = 169
Hence, the value of x is 169 centimeters
