A botanist is using two types of plants for an experiment. she writes inequalities to model the constraints on the number of each type of plant she can use. she uses linear programming to find the vertex of the feasible region that results in the minimum value, in dollars, of the cost function. if that vertex is (5, 39), what do the coordinates represent? buying five of one type of plant and 39 of the other type of plant results in the lowest cost. buying five of each type of plant costs $39, which is the lowest possible cost. the lowest possible cost of the plants is $5, which occurs when 39 of each type of plant are bought. the lowest possible cost of the plants is $5, which occurs when a total of 39 plants are bought.
The coordinates represent the numbers of plants of each type she can use and minimize the cost
Let x be the number of plants of one type.
y be the number of plants of the other type.
What is the meaning of the vertex of the feasible region?
The optimal solutions will occur at one or more of the extreme points this is the vertices of the feasible region.
We have, The vertex of the feasible region that results in the minimum value of the cost function is (5,39).
That means buying 5 of one type of plant and 39 of the other type of plant results in the lowest cost.
Thus the coordinates represent the numbers of plants of each type she can use and minimize the cost.

Find the distance between the points ( – 4,8) and ( – 4, – 5)
Answer:
they are 13 points away from eachother
Step-by-step explanation:
count up or down then left or right
Answer:
13 units.
Step-by-step explanation:
Distance = √[(x2-x1)^2 + (y2-y1)^2] where (x1,y1) and (x2,y2) are the 2 points
So here the distance = √(-4 - -4)^2 + (8 - -5)^2)

Two times the sum of four times a number plus six is the same as five less than twice the same number what is the number?
Answer:
[tex]\frac{-17}{6}[/tex]
Step-by-step explanation:
Let x be the number we want to find.
First we analyze the given informations
Info 1 : Two times the sum of four times a number plus six
We translate this statement (info 1) mathematically as : 2×(4x + 6)
Info 2 : five less than twice the same number
We translate this statement (info 2) mathematically as : 2x - 5
Info 1 is the same as Info 2 ⇔ 2×(4x + 6) = 2x - 5
2×(4x + 6) = 2x - 5
⇔ 8x + 12 = 2x - 5
⇔ 8x - 2x = -5 - 12
⇔ 6x = - 17
⇔ x = -17/6

Line A has a slope of 6. Line B has a slope of -1/6. Are these lines perpendicular?
Answer:
Yes
Step-by-step explanation
Lines are perpendicular when they have the reprocial slope with the opposite sign.
Yes, the lines having slopes 6 and -1/6 are perpendicular.
What is slope?The slope of a line is a number that describes the direction of the line. The formula of calculating slope is calculated as under:
Slope=[tex](y_{2} -y_{1} )/(x_{2} -x_{1} )[/tex].
How to identify perpendicular lines?We have been given that the slope of line A is 6 and slope of line B is -1/6.
Two lines are seem to be perpendicular to each other if the product of their slopes is equal to -1.
Product=slope of line A * Slope of line B
=6*(-1/6)
=-6/6
=-1
Hence the lines having slopes 6 and -1/6 are perpendicular to each other.

Points R(-6,-5),S(-2,-5) and T(-2,n) are plotted in the coordinate plane. The distance between points R and S is half the distance between points S and T. The value of n could be blank or blank.
The square of the distance between two points is the sum of the squares of the difference between two coordinates. The value of n can be -13 or 3.
What is the distance between two points?The distance between two points is given by the formula,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
As it is given that the distance between points R and S is half the distance between points S and T.
[tex]2(RS) = ST[/tex]
Now, the distance between RS can be written as,
[tex]RS=\sqrt{[-6-(-2)]^2+[-5-(-5)]^2}\\RS = \sqrt{(-6+2)^2+(0)^2}\\RS = \sqrt{16}\\RS = \pm 4[/tex]
Further, we can write,
[tex]2(RS) = ST\\\\2(\pm 4) = \sqrt{[-2-(-2)]^2+[-5-n]^2}\\\\\pm 8 = \sqrt{(0)^2+(-5-n)^2}\\\\\pm 8^2=(-5-n)^2\\\\\pm8=(-5-n)\\\\[/tex]
When the value of 8 is positive,

A country pledges to reduce its annual CO2
emissions by 5% per year. If the emissions in
2022 are 6,080 Mt (metric megatons), what are
the maximum allowable emissions in the year
2029?
A country pledges to reduce its annual CO₂ emissions by 5% per year, the maximum allowable emissions in the year 2029 is, 4245.89 Mt
What is the percentage?The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
Given that,
A country pledges to reduce its annual CO₂ emissions by 5% per year
The emissions in 2022 are 6,080 Mt
The maximum allowable emissions in the year 2029 = ?
In 2022 CO₂ emission = 6,080 Mt
5% reduces next year
So, In 2023
CO₂ emission = 6080(1 - 0.05)
In 2024
CO₂ emission = 6080(1 - 0.05)(1 - 0.05)
So after 7 years in 2029
CO₂ emission = 6080(1 - 0.05)⁷
= 4245.89
Hence, the maximum permissible emission is 4245.89 Mt

rewrite the function in an equivalent form the would reveal the vertex of the function f(x)=x^2+8x+6
Answer:
f(x)=(x+4)-10
Step-by-step explanation:
Since the function f(x)=x^2+8x+6 is in standard form, you need to find the axis of symmetry using the formula -b/2a, and then plug the value back into the original equation to find the vertex.
The vertex is (-4, -10)
Using this information, we can rewrite the equation in vertex form (f(x=a(x-h)+k), where (h, k) is the vertex.
The equation we rewrite is f(x)=(x+4)-10

Delta math: Angle Terminology with Equations
Answer:
m∠A = 139°
Step-by-step explanation:
First we must know that
Supplementary angles equal to 180 degree.
Since we know that supplementary angles equal to 180 degree we can solve now:
Putting m ∠A and m ∠ B together and put the = 180
( 7x - 15 ) + ( 2x - 3 ) = 180
Now solving for x:
( 7x - 15 ) + ( 2x - 3 ) = 180
9x - 18 = 180
9x - 18 + 18 = 180 + 18
9x = 198
9x/9 = 198/9
x = 22
Hence, Angle A will have a measure of 7x - 15 which means 7 × 22 -15 = 154 - 15 = 139°
m∠A = 139°
The measure of Angle B will be 2x - 3 = 2 • 22 - 3 = 44 - 3 = 41°
m∠ B = 41°
139 + 31= 180
[RevyBreeze]
Supplementary angles have sum 180°
7x-15+2x-3=1809x-18=1809x=198x=198/9x=22m<A
