Find an equation of the line L. L is perpendicular to y=-2x and is passing through points 2,-4
Answers
slope of line y= -2x is -2
slope of line L= (-1)reciprocal of slope line y= -2x.
=( -1)(-1/2)
=1/2
since the L passes through (2,-4),
equation of line L: y-(-4)= 1/2(x-2)
2y+8 = x-2
x-2y-10=0
Hence equation of line L is x-2y-10=0
The equation perpendicular to y = -2x and passing through point (2,-4) is y = x/2 - 5.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
The equation of a line with slope m is given by
y = mx + c
Now,
multiplication of slope of two perpendicular lines = -1
And,
Slope of line y = -2x ⇒ dy/dx = -2
So,
m × (-2) = -1 ⇒ m = 1/2
So,
y = (1/2)x + c
Now since it is passing by point (2,-4) so it should satisfy this
So,
-4 = 2/2 + c
c = -5
So,
y == x/2 - 5.
Hence "The equation perpendicular to y = -2x and passing through point (2,-4) is y = x/2 - 5".

Answers
Answer:
[tex]l + w + d \leq 61[/tex]
Step-by-step explanation:
Given
Sum of l, w and d be at most 61
Required
Write as inequality
First, we need to determine the sum of l, w and d
[tex]Sum = l + w + d[/tex]
Next, we determine the type of inequality.
At most 61 means less than or equal to 61
So, the expression becomes:

Rina bought 51/4 meter of cloth. She uses 3 3/4 of meter for her project.how many meter of cloth dis she have left
Answers
Answer:
1 1/4
1 1/2
Step-by-step explanation:
Given that :
Length of cloth purchased = 2 1/4
Length used for project = 3/4
Length remaining = (length purchased - length used)
= 2 1/4 - 3/4
= (9/4 - 3/4)
= (9 - 4) / 4
= 5/4
= 1 1/4
Length of cloth purchased = 5 1/4
Length used for project = 3 3/4
Length remaining = (length purchased - length used)
= 5 1/4 - 3 3/4
= 21/4 - 15/4
= (21 - 15) / 4
= 6/4
= 1 2/4
= 1 1/2
If x^2+y^2=1, what is the largest possible value of |x|+|y|?
Answers
If x² + y² = 1, then y = ±√(1 - x²).
Let f(x) = |x| + |±√(1 - x²)| = |x| + √(1 - x²).
If x < 0, we have |x| = -x ; otherwise, if x ≥ 0, then |x| = x.
• Case 1: suppose x < 0. Then
f(x) = -x + √(1 - x²)
f'(x) = -1 - x/√(1 - x²) = 0 → x = -1/√2 → y = ±1/√2
• Case 2: suppose x ≥ 0. Then
f(x) = x + √(1 - x²)
f'(x) = 1 - x/√(1 - x²) = 0 → x = 1/√2 → y = ±1/√2
In either case, |x| = |y| = 1/√2, so the maximum value of their sum is 2/√2 = √2.
An equation is formed of two equal expressions. The largest possible value of |x|+|y|=1.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

t = 8588 years
Step-by-step explanation:
From the given information:
Using the formula:
[tex]k = \dfrac{In (2)}{t_{1/2}}[/tex]
Given that:
[tex]t_{1/2}[/tex] = 5730 years
Then:
[tex]k = \dfrac{In (2)}{5730}[/tex]
[tex]k = \dfrac{0.6931472}{5730}[/tex]
k = 1.20968 × 10⁻⁴
However; the expression to find the value of x is:
[tex]x= x_oe^{-kt}[/tex]
[tex]4.6 \times 10^{-13} = 1.3 \times 10^{-12} \times e^{(-1.20968\times 10^{-4} \times t)}[/tex]
[tex]\dfrac{4.6 \times 10^{-13} }{1.3 \times 10^{-12}}= e^{(-1.20968\times 10^{-4} \times t)}[/tex]
[tex]0.353846= e^{(-1.20968\times 10^{-4} \times t)}[/tex]
(-1.20968 × 10⁻⁴ × t) = In(0.353846)
(-1.20968 × 10⁻⁴ × t) = -1.03889
[tex]t = \dfrac{-1.03889}{-1.20968 \times 10^{-4}}[/tex]

Susan's elevation at the top of a mountain is 1,530 meters. After 4 hours of climbing down her elevation is 680 meters. What is Susan’s average change in elevation, in meters per hour
A) -850
B)-382.50
C) -212.5
D) -167.5
Answers
Rate of a quantity is always in comparison to some other quantity's change. Susan’s average change in elevation, in meters per hour is given by: Option C) -212.5 meters/ hour.
How to find the average rate of change of something?Let the thing that is changing be y and the thing with which the rate is being compared is x, then we have the average rate of change of y as x changes as:
[tex]\text{Average rate} = \dfrac{y_2 - y_1}{x_2 - x_1}[/tex]
where when
[tex]x = x_1, y = y_1\\and \\x = x_2, y = y_2[/tex]
(its final value - initial value for both dependent and independent variable).
The average change in elevation in meters per hour is ratio of change in elevation in meters to time taken to do it in hours.
Therefore, it is calculated as:
[tex]A = \dfrac{ 680 - 1530}{4} = \dfrac{-850}{4} = -212.5 \: \rm meters/hour[/tex]
(if t was initial time, and t+4 was final time, then t+4-t = 4)
(also, initial height was 1530
Thus, Susan’s average change in elevation, in meters per hour is given by: Option C) -212.5 meters/ hour

Let, 'P' denotes the number of peach trees and 'A' denotes the number of apple trees.
So, A + P = 347.
Also given that he has 162 more apple trees than peach trees in his orchard which is, A = P + 162.
Therefore,
P + 162 + P = 346.
