State the value of h for which y = -x + 6 will be a tangent to the curve y = 5x^2 + 6x - 3h
Answers
y = -x + 6
y = 5x^2 + 6x - 3h
-x + 6 = 5x^2 + 6x - 3h
Now we can use the quadratic formula to solve for x:
x = (-b ± √(b^2 - 4ac)) / 2a
where a = 5, b = 6, and c = -3h - 6
x = (-6 ± √(6^2 - 4(5)(-3h-6))) / 2(5)
x = (-6 ± √(36 + 60h + 24)) / 10
x = (-6 ± √(60h + 60)) / 10
Now we can substitute this value of x back into one of the original equations to find y:
y = -x + 6
y = -(-6 ± √(60h + 60)) / 10 + 6
y = 6 ± √(60h + 60) / 10
Now we can substitute this value of x and y back into the other equation:
y = 5x^2 + 6x - 3h
6 ± √(60h + 60) / 10 = 5x^2 + 6x - 3h
Now we can use the fact that the slope of the tangent line is equal to the derivative of the function at the point of tangency.
So, the derivative of y = 5x^2 + 6x - 3h is:
dy/dx = 10x + 6
So, we can substitute x and y values back into the derivative and get the slope of the tangent line:
10x + 6 = -1
10x = -7
x = -7/10
Now, substituting this value of x back into one of the original equations to find y:
y = -x + 6
y = -(-7/10) + 6
y = 7/10 + 6
y = 61/10
So, the point of tangency is (x,y) = (-7/10, 61/10)
Finally, we can substitute this point of tangency into one of the original equations and solve for h.
61/10 = 5(-7/10)^2 + 6(-7/10) - 3h
h = (61/10 + 49/100 + 21/100 - 3h) / -3
h = (61/10 + 70/100) / -3
h = -(431/30)
Therefore, h = -(431/30) for y = -x + 6 is a tangent to the curve y = 5x^2 + 6x - 3h

If wy is the midsegment of triangle QRS. Find the value of x, if WY=80 and RS=2x+20
Answers
If wy is the midsegment of triangle QRS. Then the value of x, if WY=80 and RS=2x+20 is calculated to be 70.
In a triangle, the midsegment connecting the midpoints of two sides is equal to the half the length of the third side. Therefore, we have:
WY = 0.5 x RS
Substituting the given values, we will be getting,
80 = 0.5 x (2x+20)
Simplifying this equation, we get:
80 = x + 10
Subtracting 10 from both sides, we get:
x = 70
Therefore, from the calculations above, it can be concluded that the value of x is found oout to be 70.

Answers
The number of pounds of candy that sells for $0.79 per lb that must be mixed with candy that sells for $1.35 per lb to obtain 8 tons of a mixture that should sell for $335 per ton is 580 pounds
How to know the amount of pounds of candy requiredTake x as the number of pounds of candy that sells for $0.79 per lb, and y as the number of pounds of candy that sells for $1.35 per lb.
x + y = 8 (i.e total amount of candy to be mixed)
0.79x + 1.35y = 335 (desired selling price per ton)
solve for x
y = 8 - x
0.79x + 1.35(8 - x) = 335
0.79x + 10.8 - 1.35x = 335
-0.56x = 324.2
x = 579.64
Thus x ≈ 580 to the nearest pound
Hence, about 580 pounds of candy that sells for $0.79 per lb must be mixed with candy that sells for $1.35 per lb to obtain 8 tons of a mixture that should sell for $335 per ton.

Step-by-step explanation:
I need the image that I am going to attach to solve the exercise.
We have the following information:
Confetti height from the ground is 25 feet

A model of carry-on luggage has a length that is inches greater than its depth. Airline regulations require that the sum of the length, width, and depth cannot exceed inches. These conditions, with the assumption that this sum is inches, can be modeled by the function V(x) that gives the luggage's volume, in cubic inches, in terms of its depth, x, in inches. If its volume is cubic inches, determine two possibilities for its depth.
V(x)

[(xx)]
V(x)
Answers
The two possibilities for the depth of the luggage are: depth = inches / 2
or depth = 0 (but this solution does not make sense)
The sum of the length, width, and depth of the luggage cannot exceed a certain value, so we can write:
\(length + width + depth < = limit\)
We also know that the length is inches greater than the depth, so we can write:
length = depth + inches
We want to find the volume of the luggage, which is given by:
\(volume = length * width * depth\)
Substituting the expression for length in terms of depth, we get:
volume = (depth + inches) * width * depth
To eliminate the width, we can use the fact that the volume is a fixed value, so we can write:
width = volume / (depth + inches) / depth
Substituting this expression for width, we get:
volume = (depth + inches) * (volume / (depth + inches) / depth) * depth
Simplifying this expression, we get:
volume =\(volume * depth / (depth + inches)\)
Multiplying both sides by (depth + inches), we get:
volume * (depth + inches) = volume * depth
Expanding the left side, we get:
volume * depth + volume * inches = volume * depth
Subtracting volume * depth from both sides, we get:
volume * inches = -volume * depth
Dividing both sides by volume, we get:
inches = -depth
Since depth cannot be negative, we have:
depth = 0
This solution does not make sense, so we need to consider the other possibility:
depth + inches = -depth
Solving for depth, we get:
depth = -inches / 2
Since the depth cannot be negative, we have:
depth = inches / 2
Therefore, two possibilities for the depth of the luggage are:
depth = inches / 2
or
depth = 0 (but this solution does not make sense)

CHECK THE COMPLETE QUESTION
The telephone company offers two billing plans for local calls. Plan 1 charges $30 per month for unlimited calls and Plan 2 charges $15 per month plus $0.04 per call.
a. Use an inequality to find the number of monthly calls for which Plan 1 is more economical than Plan 2.
b. Explain the meaning of the answer to part
We can denote the number of calls as "y"
From plan 1, the Total monthly charge is $30
From plan 2, the Fix charge is $15 with $0.04 per call
We can expressed the cost of "y" call as( $0.04y)
From plan2, The monthly charge can be expressed as (0.04x + 15)
a. Use an inequality to find the number of monthly calls for which Plan 1 is more economical than Plan 2.
Here, Plan 1 is more economical than plan 2.
0.04y + 15 > 30
Collect like terms we have
0.04y > 30-15
0.04y> 15
y > 375
b) in case, more than 375 calls are made,then the economical plan is plan 1
P is a rectangle with a length of 40 cm and a width of x cm q is a rectangle with a width of y cm the length of q is 25% more than the length of p the area of q is 10% less than the area of p work out the ratio of x:y
Answers
In rectangles P and Q, where the area of rectangle Q is 10% less than the area of rectangle P, we have the ratio of x:y = 25:18.
The area of a rectangle is the product of its length and its width.
In the question, we are given two rectangles:-
Rectangle P:
length = 40 cm,
width = x cm,
Thus, the area = length * width = 40x.
Rectangle Q:
length = 25% more than the length of P = 40 + 25% of 40 = 40 + 0.25*40 = 40 + 10 = 50 cm.
width = y cm,
Thus, the area = length * width = 50y.
Now, we are given that, the area of rectangle Q is 10% less than the area of rectangle P.
Thus, we can write that,
Area of rectangle Q = Area of rectangle P - 10% of the area of rectangle P,
or, 50y = 40x - 10% of 40x,
or, 50y = 40x - 0.10*40x,
or, 50y = 40x - 4x,
or, 50y = 36x,
or, y = 36x/50.
We are asked to find the ratio of x:y = x/y.
Substituting y = 36x/50, we get,
x/y = x/(36x/50) = 50x/36x = 25/18.
Thus, the ratio x:y = 25:18.
Thus, in rectangles P and Q, where the area of rectangle Q is 10% less than the area of rectangle P, we have the ratio of x:y = 25:18.

A five-member committee is to be selected from 7 Form Six students and 5 Form Five students. Find the probability that i) exactly 3 Form Six students are selected. at least 4 Form Six students are selected. at least 1 Form Five student are selected. (8 marks) ii)
Answers
To find the probabilities, we need to determine the total number of possible committees and the number of favorable outcomes for each case.
Let's calculate each probability step by step:
(i) Probability of exactly 3 Form Six students being selected:
To calculate this, we need to choose 3 Form Six students from 7 Form Six students and 2 Form Five students from 5 Form Five students. The total number of possible committees is the combination of selecting 5 members from the total of 12 students.
Total number of possible committees = C(12, 5) = 792
The number of favorable outcomes is choosing 3 Form Six students from 7 and 2 Form Five students from 5.
Number of favorable outcomes = C(7, 3) * C(5, 2) = 35 * 10 = 350
The probability of exactly 3 Form Six students being selected is:
Probability = Number of favorable outcomes / Total number of possible committees
Probability = 350 / 792 ≈ 0.442
(ii) Probability of at least 4 Form Six students being selected:
To calculate this, we need to consider the cases where 4 Form Six students or all 5 Form Six students are selected. The total number of possible committees is the same as before, C(12, 5) = 792.
Number of favorable outcomes for selecting exactly 4 Form Six students = C(7, 4) * C(5, 1) = 35 * 5 = 175
Number of favorable outcomes for selecting all 5 Form Six students = C(7, 5) = 21
The probability of at least 4 Form Six students being selected is the sum of these two probabilities:
Probability = (Number of favorable outcomes for selecting exactly 4 Form Six students + Number of favorable outcomes for selecting all 5 Form Six students) / Total number of possible committees
Probability = (175 + 21) / 792 ≈ 0.243
(iii) Probability of at least 1 Form Five student being selected:
To calculate this, we need to consider the cases where at least 1 Form Five student is selected. The total number of possible committees is still C(12, 5) = 792.
Number of favorable outcomes = Total number of possible committees - Number of committees with only Form Six students
Number of committees with only Form Six students = C(7, 5) = 21
The probability of at least 1 Form Five student being selected is:
Probability = Number of favorable outcomes / Total number of possible committees
Probability = (792 - 21) / 792 ≈ 0.973
By calculating these probabilities using the formulas and values mentioned above, we obtain the following answers:
(i) Probability of exactly 3 Form Six students being selected ≈ 0.442
(ii) Probability of at least 4 Form Six students being selected ≈ 0.243
(iii) Probability of at least 1 Form Five student being selected ≈ 0.973
Please note that the probabilities are approximations rounded to three decimal places.
