Find an equation of the line parallel to 8x − 3y = 1 and containing the point (−2, 0)
The equation of the line parallel to 8x − 3y = 1 and containing the point (−2, 0) is 8x -3y = -16
Equation of a straight lineFrom the question, we are to determine the equation of the line parallel to the given equation and that passes through the given point
Lines that are parallel to each other will have the same slope.
First, we will determine the slope of the line in the given equation.
The given equation of the line is
8x − 3y = 1
Express the equation in the slope-intercept form of a line, y = mx + b
Where m is the slope and
b is the y-intercept
That is,
8x − 3y = 1
8x -1 = 3y
3y = 8x - 1
y = 8/3(x) - 1/3
By comparing,
∴ The slope of the line is 8/3
Since we are to find the equation of a line parallel to this, the slope of the line will also be 8/3
Now, find the equation of a line containing the point (-2, 0) and that has a slope of 8/3
Using the point-slope form of a line
y - y₁ = m(x - x₁)
x₁ = -2
and y₁ = 0
∴ y - 0 = 8/3(x - -2)
y = 8/3(x +2)
3y = 8(x +2)
3y = 8x + 16
8x -3y = -16
Hence, the equation of the line parallel to 8x − 3y = 1 and containing the point (−2, 0) is 8x -3y = -16

The data in the table represents the volume of helium, in cubic feet, inside a balloon relative to the elapsed time in minutes.
The interpretation of the slope is that (b) the volume of helium in the balloon decreases at a rate of 0.1 cubic per minute
What are linear equations?Linear equations are equations that have constant average rates of change, slope or gradient
How to determine the slope?From the table of values, we have the following points
(x, y) = (5, 5.5) and (10, 5)
The slope of the table of values is calculated as:
m = (y2 - y1)/(x2 - x1)
Substitute the known values in the above equation
m = (5 - 5.5)/(10 -5)
Evaluate the difference
m = -0.5/5
Evaluate the quotient
m = -0.1
This means that the slope is -0.1
From the table of values, we have
x represents the elapsed time and y represents the volume of helium
So, the interpretation of the slope is that (b) the volume of helium in the balloon decreases at a rate of 0.1 cubic per minute

Dave is helping his grandmother make trail mix. His grandmother asks him to add 1/5 cup of fruit for every 1/3 cup of nuts.
Answer:
dave needs 3/5
Step-by-step explanation:
Step-by-step explanation:
what is the question ?
what problem needs to be solved ?
is it to find the ratio between fruit and nuts ?
then remember, a ratio is a fraction.
so, the ratio fruit : nuts is
1/5 / 1/3 = 1×3 / 5×1 = 3/5 or 3 : 5
or is it about any fraction problems and we need to bring them to the same denominator to add our compare them ?
to compare the 1/5 cup of fruit with the 1/3 cup of nuts, the smallest common multiple of 5 and 3 is 15. so we need to bring all to .../15.
how to make 15 out of 5 ? by multiplying 5 by 3. and we need to do this on the top of the fraction as well to keep the original value of the fraction.
1/5 = 1/5 × 3/3 = 3/15.
and with the same line of thinking :
1/3 = 1/3 × 5/5 = 5/15.
so, when mixing 1/5 cup of fruit with 1/3 cup of nuts, we get 3/15 + 5/15 = 8/15 cup of trail mix.
here you can clearly see the ratio again : 3/15 : 5/15 = 3:5
the first solution to get only full cups of trail mix is
3 cups of fruit and 5 cups of nuts = 8 cups of trail mix.
anything less will always end up with parts of cups (since 3/5 can't be simplified anymore).
Se the laplace transform to solve the given initial-value problem. y'' − y' = et cos t, y(0) = 0, y'(0) = 0
The solution to this problem is (s2+1)Y(s)−2s−1=2s2+4 .
We let L[y(t)]=Y(s) . With that, tabular Laplace-transform laws entail
L[y′]=sY(s)−y(0)=sY(s)−2
L[y′′]=s2Y(s)−sy(0)−y′(0)=s2Y(s)−2s−1
∴L[y′′+y]=(s2+1)Y(s)−2s−1 .
Since the Laplace transform of sin(kt) is ks2+k2 , we have
(s2+1)Y(s)−2s−1=2s2+4 .
This equation readily solves to Y(s)=2s3+s2+8s+6(s2+1)(s2+4) . We compute its partial fraction decomposition as Y(s)=2s+53s2+1+−23s2+4 .
Our final step is to use tabular Laplace-transform laws ( sin(kt)↦ks2+k2 , and cos(kt)↦ss2+k2 ) to get y(t)=2cost+53sint−13sin(2t) . One can check that this indeed satisfies the initial value problem.

The value of λ = 8s + 6
What are the zeroes of a function?The zeroes of a function f(x) are the values of x at which f(x) = 0.
How to find λ?Given that a, s are the zeroes of 2 - 8x + λ ,such that a - s = 2.
Since we require λ,
So, let f(x) = 2 - 8x + λ.
At x = a, f(x) = 0.
So, substituting the value of x = a into f(x), we have
f(a) = 2 - 8a + λ
Since f(a) = 0, we have
2 - 8a + λ = 0
2 + λ = 8a (1)
Also, x = s, f(x) = 0.
So, substituting the value of x = s into f(x), we have
f(s) = 2 - 8s + λ
Since f(s) = 0,we have
2 - 8s + λ = 0
2 + λ = 8s (2)
Since a - s = 2
Making a subject of the formula, we have
⇒ a = s + 2
So, substituting the value of a into equation (1), we have
2 + λ = 8a (1)
2 + λ = 8(s + 2) (1)
2 + λ = 8s + 16
- 14 + λ = 8s (3)
Adding equation (2) and (3), we have
-14 + λ = 8s (3)
+
2 + λ = 8s (2)
-12 + 2λ = 16s
2λ = 16s + 12
Dividing through by 2, we have
2λ/2 = (16s + 12)/2
λ = 4(4s + 3)/2
λ = 2(4s + 3)
λ = 8s + 6

The experimental probability the placebo pill induced better concentration on the student exams is 0.64
The question has to do with probability.
What is probability?Probability is the likelihood of an event occurring.
The probability of an event A is given by
P(A) = number of occurrences of event A/total number of occurrences of all events.
What is the experimental probability the placebo pill induced better concentration on the student exams?Given that in the study on the placebo effect on 100 students, 64 were found to perform better on tests after taking a fake pill to improve concentration.
The event A = students performing better.
Since 64 students performed better, the number of occurrences of event A = 64.
Since there were 100 students, the total number of occurrences = 100.
So, P(A) = P(students perform better)
= number of occurrences of event A/total number of occurrences of all events.
= 64/100
= 0.64

pls solve if u can <3 much appreciated
Step-by-step explanation:
that is only possible, if we don't need to use a 2 and a 5 (but especially the 2) to create the 1 in the middle (log(10) = log(2×5) or log (5×2) = 1).
in other words, if the 1 in the middle is just a given, and does not use any of our digits for is creation, then a solution is possible.
first of all, the upper left corner has to be log(0⁰). we cannot use the digit 0 for anything else. and 0^n (except for n = 0) is not a valid argument for a logarithm.
log(0⁰) = 0 log(2×1) = 0.3... log(9/4) = 0.35...
log(1×2) = 0.3... 1 log(3×6) = 1.26...
log(7/3) = 0.37... log(4×5) = 1.3... log(6⁹) = 7.0...
but as soon as we need to build the center 1 by log(10), which takes then away one of the 2s (as the only way to build 10 by multiplication is 2×5 or 5×2), there is no possible solution.

Based on the coordinates of the vertices of the parallelogram ORST, the coordinates of S can be found to be (a + b, d).
What are the coordinates of point S?As this is a parallelogram, the horizontal distance between O and R would be the same as the horizontal distance between S and T.
The horizontal distance between O and R is represented by "b".
