Determine the equation of the line below using the given slope and point.
Slope = m = 4 , Point (-3,-11)
\((\stackrel{x_1}{-3}~,~\stackrel{y_1}{-11})\hspace{10em} \stackrel{slope}{m} ~=~ 4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-11)}=\stackrel{m}{ 4}(x-\stackrel{x_1}{(-3)}) \implies y +11 = 4 ( x +3) \\\\\\ y+11=4x+12\implies {\Large \begin{array}{llll} y=4x+1 \end{array}}\)
The equation is:
⇨ y + 11 = 4(x + 3)Work/explanation:
Recall that the point slope formula is \(\rm{y-y_1=m(x-x_1)}\),
where m is the slope and (x₁, y₁) is a point on the line.
Plug in the data:
\(\rm{y-(-11)=4(x-(-3)}\)
Simplify.
\(\rm{y+11=4(x+3)}\)
Hence, the point slope equation is y + 11 = 4(x + 3).Simplified to slope intercept:
\(\rm{y+11=4x+12}\)
\(\rm{y=4x+1}\) <- this is the simplified slope intercept equation

How far does the tip of a minute hand on a clock travel in 15 minutes if the distance from the center to the tip is 8cm? Leave your answers in terms of pi or round your answer to the nearest tenth.
SHOW WORK
The tip of the minute hand on a clock travels a distance of 4π inches in 15 minutes.
How to find the distance of the tip minute handThe distance traveled by the tip of a minute hand on a clock can be calculated using the circumference formula.
The circumference of a circle is given by the formula:
C = 2πr C is the circumference, π is pi (approximately 3.14159) and r is the radius.
The distance from the center of the clock to the tip of the minute hand is the radius is 8 centimeters.
The circumference of the circle traced by the tip of the minute hand is:
\(\text{C} = 2\pi \text{r}\)
\(= 2\pi (8)\)
\(= 16\pi \ \text{centimeters}\)
Since the minute hand travels the full circumference of the circle in 60 minutes, in 15 minutes it will cover 15/60 = 1/4 of the circumference.
The distance traveled by the tip of the minute hand in 15 minutes is:
\(\text{Distance} = \huge \text(\dfrac{1}{4}\huge \text) \times C\)
\(= \huge \text(\dfrac{1}{4}\huge \text) \times (16\pi)\)
\(= 4\pi \ \text{centimeters}\)

https://brainly.com/question/32037529
Answer:
4π cm ≈ 12.6 cm
Step-by-step explanation:
The clock can be modelled as a circle, where the radius (r) is equal to the length of the minute hand: r = 8 cm.
A clock face is divided into 12 equal sectors (numbered 1 to 12).
It takes 60 minutes for the minute hand to complete one revolution of the clock. Therefore, each sector represents the passing of 5 minutes.
This means that 15 minutes equals 3 sectors, which is a quarter of the circle.
To find the distance the tip of the minute hand travels in 15 minutes, we need to find a quarter of the circumference of a circle with radius 8 cm.
The formula for the circumference of the circle is C = 2πr, where r is the radius. Therefore, the equation to find the distance the tip of the minute hand travelled in 15 minutes is:
\(\sf Distance=\dfrac{2 \cdot \pi \cdot 8}{4}\)
Simplifying, we get:
\(\sf Distance=\dfrac{16 \cdot \pi}{4}\)
\(\sf Distance=4 \pi\)
Therefore, the minute hand will travel 4π cm or approximately 12.6 cm (to the nearest tenth) in 15 minutes.

) you use, you are charged $0.25
and for each therm (t
) of gas used you are charged $0.97
.
Which of the following equations represents the relationship between electricity and gas used and your bill?
The equation representing the relationship between Electricity and Gas used, and your Bill is:
T = 0.25 * k + 0.97 * t
Step-by-step explanation:
Make a plan:
We need to find the equation that represents the relationship between the total monthly bill (T), The Kilowatt Hours of Electricity used (k), and the Terms of Gas used (t).
T = 0.25 * k + 0.97 * t
Solve the problem:
1 - Write the Equation for the cost of Electricity:
0.25 * k
2 - Write the Equation for the Cost of Gas:
0.97 * t
3 - Combine the Equations to Represent the total Monthly Bill (T):
T = 0.25 * k + 0.97 * t

Flora paid her supplier $0.75 a stem for roses to sell at her flower shop. She added an 80% markup. What is the amount of markup?
Answer:
$0.60
Step-by-step explanation:
the question ask us to find the amount of the markup on Flora’s roses. The amount of markup is given by:
markup rate x original price = amount of markup
the markup rate is in decimal form
since the original price was $0.05 and the markup price is 80% = 0.80, we have
0.80 x .075 = 0.60
thus, the amount of the markup on Flora’s roses was $0.60

In 1995, wolves were introduced into Yellowstone Park.
The function `w\left(x\right)=14\cdot1.08^{x}` models the number of wolves, `w`, in the years since 1995, `x`.
According to the model, about how many years will it take for the population to reach `500` wolves?
According to the information we can infer that it will take approximately 31 years for the wolf population to reach 500.
How to calculate how many years will it take for the population to reach 500 wolves?The given function, w(x) = 14 * 1.08^x, models the number of wolves (w) in the years since 1995 (x).
To find the number of years it will take for the population to reach 500 wolves, we can set up the equation:
500 = 14 * \(1.08^{x}\)Dividing both sides by 14, we get:
35.714 ≈ \(1.08^{x}\)Taking the logarithm (base 1.08) of both sides to solve for x:
log₁.₀₈ (35.714) ≈ log₁.₀₈ (\(1.08^{x}\))x ≈ log₁.₀₈ (35.714)Using a calculator, we find that x ≈ 31.
According to the above it will take approximately 31 years for the wolf population to reach 500 based on the given model.

During her holiday, Hannah rents a bike. She pays a fixed cost of $8 and then a cost of $4.50 per day.
Hannah pays with a $50 note and receives $10.50 change.
Calculate for how many days Hannah rents the bike.
fixed cost= $8
cost= $4.50
payed= $50
recieved= $10.50
to find:how many days Hannah rented the bike.
solution:let the unknown be ( x )
\(x = 50 - (10.50 + 8)\)
\(x = 50 - 18.50\)
\(x = 13.50\)
\(x = \frac{13.50}{4.50} \)
\(x = 7\)
hence, Hannah rented the bike for 7 days.
Which equation represents a circle with the same

O (x-4)² + (y-5)² = 4
O (x-5)2 + (y-4)² = 2
O(x - 5)² + (y-4)² = 4
The equation of the circle is (x - 4)^2 + (y - 5)^2 = 4
How to determine the equation of the circleFrom the question, we have the following parameters that can be used in our computation:
The graph
A circle equation is represented as
(x - a)^2 + (y - b)^2 = r^2
Where
Center - (a, b)
From the graph, we have
(a, b) = (4, 5)
So, we have
(x - 4)^2 + (y - 5)^2 = r^2
The radius is 2
So, we have
(x - 4)^2 + (y - 5)^2 = 2^2
Evaluate
(x - 4)^2 + (y - 5)^2 = 4
Hence, the equation is (x - 4)^2 + (y - 5)^2 = 4

A person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen he sells it at Rs 80 a pair find the gain percent pls do it step by step
Answer:
33.3%
Step-by-step explanation:
To get the gain percent, first we need to calculate the unit selling price and cost of each cosmetics.
If a person bought some cosmetics from wholesale market at the rate of Rs 360 per dozen., then one cosmetic will cost 360/12 = Rs. 30
Also if he sells it at Rs 80 a pair, then he sold one cosmetic at 80/2 = Rs. 40
Selling price = Rs. 40
Cost price = Rs. 30
% gain = SP-CP/CP * 100%
% gain = 40-30/30 * 100
% gain = 10/30 * 100
% gain = 100/3
% gain = 33.3%
Hence the percentage gain is 33.3%
