-5 a root of the Quadratic
equation n² - 8n-65 = o.
What is the other root of the
equation
Answers
Answer:
13
Step-by-step explanation:
It is a quadratic equation meaning it has 2 factors and since one of it has root -5, the first factor is (n + 5),
So, we have (n + 5)(n + a) = n^2 + an + 5n + 5a
Thus, by comparison,
n^2 + (5 + a)n + 5a = n^2 - 8n - 65 = 0
5 + a = -8
5a = -65
a = -13
Thus, the other factor is (n -13) and root is 13
A manufacturer is planning to sell a new product for $150 each and estimates that if it spends x thousand dollars on development and y thousand dollars on promotion will sell approximately
320y/(y+2) + 160x/(x+4) unit
The cost to produce each unit of that product is $50. If the producer spends a total of $8,000 on development and promotion, how should this money be allocated to get the maximum profit?
Answers
The maximum profit is achieved when the manufacturer spends $4,000 on development and $4,000 on promotion.
How to calculate the profitThe profit is given by
(150 - 50) * (320y/(y+2) + 160x/(x+4)) - x - y
= 100 * (320y/(y+2) + 160x/(x+4)) - x - y
= 32000y/(y+2) + 16000x/(x+4) - x - y
We want to maximize this function subject to the constraint that x + y = 8.
We can do this by using Lagrange multipliers. The Lagrangian is given by
L = 32000y/(y+2) + 16000x/(x+4) - x - y + lambda(x + y - 8)
Setting the partial derivatives of L with respect to x, y, and lambda equal to zero, we get the following equations:
32000/(y+2) - 1 - lambda = 0
16000/(x+4) - 1 - lambda = 0
x + y - 8 = 0
Solving these equations, we get x = 4, y = 4, and lambda = 0.
Therefore, the maximum profit is achieved when the manufacturer spends $4,000 on development and $4,000 on promotion.

The decorating committee for a school
banquet decides to put flowers on each table. Each
batch of flowers will have 3 white carnations and
5 yellow carnations. The committee will need 60
white carnations. What is the total number of
white
and yellow carnations the committee will
need?
A. 20
B. 100
C. 120
D. 160
Answers
Answer:
D. 160
Step-by-step explanation:
This question can be solved by proportions, using a rule of three.
In this question:
For each 3 white carnations, 5 yellows are needed, which leaves us with 8 total carnations. So for 60 white, the total is:
3 white - 8 total
60 white - x total
So
[tex]3x = 60*8[/tex]
Dividing both sides by 3
[tex]x = 20*8 = 160[/tex]
The correct answer is given by option D.

m∠A = 48.81°
Step-by-step explanation:
Given triangle is a right triangle and we have to measure ∠A.
Since, opposite side and adjacent sides of angle A has been given
So we will apply tangent rule to get the measure of angle A.
tan(∠A) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(∠A) = [tex]\frac{8}{7}[/tex]
∠A = [tex]\text{tan}^{-1}(\frac{8}{7})[/tex]
∠A = 48.814

What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Given that side lengths of a triangle are 12, 19, and x units.
We need to find the value of x.
We know that the third side of any triangle must be more than the difference between the other two sides.
x is greater than difference of nineteen and twelve
x>19-12
x>7 (or) 7<x
The third side of any triangle must be less than the sum of the other two sides.
x<19+12
x<31 (or) 31>x
From this we get the interval as
