What is the slope of a line that is perpendicular to the line whose equation is 5y+2x=12?
A. 5/2
B. −2/5
C. −5/2
D. 2/5
Answer:
A
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 )
Rearrange 5y + 2x = 12 into this form
Subtract 2x from both sides
5y = - 2x + 12 ( divide all terms by 5 )
y = - [tex]\frac{2}{5}[/tex] + [tex]\frac{12}{5}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{2}{5}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is

If anyone could please help me with this question???I know that you can get three triangles out of the shape.
Answer:
See below.
Step-by-step explanation:
The triangles are similar because the angles marked 125 are equal and the sides either side of these angle are in the same ratio:
1.3 / 2.5 = 2.6 /5.
If we are given the length of AE we would find CF from the equation:
1.3 / 2.5 = CF / AE
CF = (1.3 * AE) / 2.5.
What are the x-intercepts of the graph of the function below?
y = x2 + 2x-15
Answer:
-15
Step-by-step explanation:
the y-intercept would be -15
Answer:
x = - 5, x = 3
Step-by-step explanation:
To find the x- intercepts let y = 0, that is
x² + 2x - 15 = 0
Consider the factors of the constant term (- 15) which sum to give the coefficient of the x- term (+ 2)
The factors are + 5 and - 3, since
5 × - 3 = - 15 and 5 - 3 = + 2, hence
(x + 5)(x - 3) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
x - 3 = 0 ⇒ x = 3
x- intercepts at (- 5, 0) and (3, 0)

Where "r" is the radius and "h" is the height of the cone.
In this case you know that this cone has a height of 2.5 inches and a radius of 5 inches. Then:
[tex]h=2.5\ in\\r=5\ in[/tex]
Finally, you need to substitute these values into the formula. Then you get that the volume of the cone is:

Tyler knows that the ratio of male to female horses on the farm is 2 to 3. If there are 12 male horses, how many female horses are there?
20 POINTS
Answer:
18 female horses.
Step-by-step explanation:
By proportion 2 : 3 = 12 : x where x is the number of female horses.
12 / 2 = x / 3
2x = 3*12 = 36
x = 18.
Find the x coordinate of the point.
Answer:
x= -17
Step-by-step explanation:
When we have 2 points, we can find the slope using
m = (y2-y1)/(x2-x1)
Substituting what we know
1/5 = (0-3)/(x--2)
1/5 = -3/(x+2)
Using cross products
1*(x+2) = 5*(-3)
x+2 = -15
Subtract 2 from each side
x+2-2 = -15-2
x=-17

Find the sample Standard deviation and the population standard deviation of the data set? 17,37,56,16,12,16,19,45,14,37,21,26,43,46,42
Answer:
The sample standard deviation is 14.458
The population standard deviation is 13.967
Step-by-step explanation:
* Lets revise the population standard deviation (σ)
1. Work out the Mean (μ) (average of the numbers)
2. Then for each number subtract the Mean and square
the result (xi - μ)²
3. Then work out the mean of those squared differences
[∑(xi - μ)²/N]
4. Take the square root of that (√[∑(xi - μ)²/N]) and to find σ
* Lets revise the sample standard deviation (s)
1. Work out the Mean (x) (average of the numbers)
2. Then for each number subtract the Mean and square
the result (xi - x)²
3. Then work out the mean of those squared differences [∑(xi - x)²/N - 1]
4. Take the square root of that (√[∑(xi - x)²/N - 1]) and to find s
* Now lets solve the problem
- The data are 15 numbers
17 , 37 , 56 , 16 , 12 , 16 , 19 , 45 , 14 , 37 , 21 , 26 , 43 , 46 , 42
∵ x = μ = sum/number
∴ x = μ = (17+37+56+16+12+16+19+45+14+37+21+26+43+46+42)÷15=29.8
- Subtract the mean from each number and square the result
∵ (17 - 29.8)² = 163.84
∵ (37 - 29.8)² = 51.84
∵ (56 - 29.8)² = 686.44
∵ (16 - 29.8)² = 190.44
∵ (12 - 29.8)² = 316.84
∵ (16 - 29.8)² = 190.44
∵ (19 - 29.8)² = 116.64
∵ (45 - 29.8)² = 231.04
∵ (14 - 29.8)² = 249.64
∵ (37 - 29.8)² = 51.84
∵ (21 - 29.8)² = 77.44
∵ (26 - 29.8)² = 14.44
∵ (43 - 29.8)² = 174.24
∵ (46 - 29.8)² = 262.44
∵ (42 - 29.8)² = 148.84
∴ ∑(xi - μ)² = ∑(xi - x)² = 2926.36
∵ N = 15
∴ The sample standard deviation = √[∑(xi - x)²/(N - 1)]
∴ s = √[2926.36/(15 - 1)] = 14.458
∴ The population standard deviation = √[∑(xi - μ)²/N]
∴ σ = √[2926.36/15] = 13.967

What are the coordinates of the point shown on the
coordinate plane?
x-coordinate =
y-coordinate =
Final answer:
The coordinates of the point are (4, 3), where 4 is the x-coordinate (horizontal direction) and 3 is the y-coordinate (vertical direction).
Explanation:
The coordinates of a point on a Cartesian coordinate system are determined by its horizontal position (x-coordinate) and its vertical position (y-coordinate). Given that the point is on the first coordinate axis (x-axis) and in the (1, 2)th coordinate plane, we understand that the x-coordinate is related to the horizontal direction and the y-coordinate is related to the vertical direction.
In the context of this problem, if the figure on the coordinate plane indicates that the point is 4 units to the right of the origin along the x-axis and 3 units above the origin along the y-axis, then the coordinates of the point are ( extbf{4}, extbf{3}). Here, the convention is that moving to the right of the origin increases the x-coordinate and moving upwards increases the y-coordinate.
Lynn is taking a trip in her car. She spent 387.00 on gasoline and snacks. Lynn spent 35.80 on snacks for the entire trip. Gasoline costs 2.54 per gallon.
How many gallons of gasoline did Lynn purchase on her trip?
Answer:
138.27 gallons
Step-by-step explanation:
Total cost = snacks + gallons * cost per gallon
387 = 35.80 + g*2.54
Subtract 35.80 from each side
387-35.80 = 35.80-38.50 + g*2.54
351.20= + g*2.54
Divide by 3.54 on each side
351.20/2.54 = 2.54g/2.54
138.2677165 = g
Rounding to the nearest hundredth
138.27 gallons
Given : Lynn spent 387.00 on gasoline and snacks
Given : Lynn spent 35.80 on snacks for the entire trip
Money spent on gasoline :
Total money spent on gasoline and snacks - Money spent on snacks
[tex]:\implies[/tex] Money spent on gasoline = 387.00 - 35.80
[tex]:\implies[/tex] Money spent on gasoline = 351.20
Given : Gasoline costs 2.54 per gallon

Chad Roth took out a $9,100 simple interest loan at 10% for 36 months. After 27 payments, the balance is $2,526.85. He pays off the loan when the next payment is due.
a.) What is the CURRENT month's interest?
b.) What is the final payment?
Answer:
a) Current Interest is $75.8
b) the final payment will be $11,830
Step-by-step explanation:
Principal Amount = $9,100
Interest rate = 10% or 0.1
Time = 36 months = 3 yeras
Balance after 27 payments = $2,526.85
a) What is the CURRENT month's interest?
The formula to find interest is:
Interest = P*r*t
P= Principal
r = Interest rate
t = time in years
Interest = 9100*0.1*3
Total Interest = 2730
As total period is 36 months so, divide total interest by 36
Current Month Interest = 2730/36
Current Month Interest = 75.8
So, current month interest is $75.8
b) What is the final payment?
The formula used will be
A = P(1+r*t)
A = Final amount
r = interest rate
t = time
Putting values:
A = P(1+r*t)
A = 9100*(1+0.1*3)
A = 9100*(1.3)
A = 11,830
So, the final payment will be $11,830
