There are 108 major sources of pollen in state A. These pollen sources are categorized as grasses, weeds, and treesIf the number of weeds is 7 less than thrice the number of grasses, and the number of trees is 3 more than thrice the number of grasses, find the number of grasses, weeds, and trees that are major pollen sources.
There are 51 trees, 41 weeds, and 16 grasses that are significant pollen producers.
In the context of beekeeping, the phrase "pollen source" refers to flowering plants that provide pollen to bees and other insects. Bees gather pollen to use as a source of protein for their young.
G, W, and T should stand for the number of grasses, weeds, and trees that serve as significant pollen sources.
According to information provided, state A is home to 80 significant sources of pollen. This data can be represented as follows in an equation:
G + W + T = 108......(1)
According to what is said, there are 7 times as many weeds as there are grasses. This data can be represented as follows in an equation:
W = 3G - 7......(2)
We are also informed that there are three times as many trees as there are grasses. This data can be represented as follows in an equation:
T = 3G + 3
We are also informed that there are three times as many trees as there are grasses. This data can be represented as follows in an equation:
G + W + T = 108
G + 3G - 7 + 3G + 3 = 108
7G - 4 = 108
7G = 112
G= 112/7
G = 16
Therefore, there are 16 grasses that are major pollen sources.
Number of weeds that are major pollen sources:
W = 3G - 7 = 3(16) - 7 = 48 - 7 = 41
Therefore, there are 41 weeds that are major pollen sources.
Number of trees that are major pollen sources:
T = 3G + 3 = 3(16) + 3 = 48 + 3 = 51
Therefore, there are 51 trees that are major pollen sources.

When we solve the equation by combining both equations in one, the variable will become 0.Proof
\( \begin{cases} y = 4x - 3 \\ y = 4x - 5 \end{cases} \\ 4x - 3 = 4x - 5 \)
Combine like terms.
\(4x - 4x = - 5 + 3 \\ 0 = - 2\)

Sophie deposited money into an account in which interest is compounded
semiannually at a rate of 2.2%. She made no other deposits or withdrawals and the
total amount in her account after 13 years was $22,099.87. How much did she
deposit? Round answer to nearest whole number. Do not include units in the
answer. Be sure to attach your work for credit.
By using compound interest formula, we conclude that Sophie deposited $16,638 (rounded to the nearest whole number) into the account.
What is compound interest?Compound interest is a method of calculating interest on a principal amount of money, where the interest earned on the initial principal is added to the principal at the end of each compounding period (usually monthly, quarterly, or annually).
According to given information:We can use the formula for compound interest to solve this problem. The formula is:
\(A = P(1 + r/n)^{(nt)\)
Where:
A = the total amount in the account
P = the principal (initial deposit)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
We know the values for A, r, n, and t, so we can solve for P:
\(A = P(1 + r/n)^{(nt)\)
\(22,099.87 = P(1 + 0.022/2)^{(2*13)\)
\(22,099.87 = P(1.011)^{26\)
22,099.87 = 1.329P
P = 22,099.87 / 1.329
P = 16,637.55
Therefore, Sophie deposited $16,638 (rounded to the nearest whole number) into the account.

The number of automobiles in a certain town was 1,890 in 2015, and it was 2,420 in 2020. If we were to make a linear model that gives the number of automobiles in this town as a function of the number of years since 2015, what would be the y-intercept?
The y-intercept of the linear model is 211,400, which represents the estimated number of automobiles in the town in the year 2015 (when the independent variable is zero).
To find the y-intercept of the linear model, we need to determine the value of the dependent variable (the number of automobiles) when the independent variable (the number of years since 2015) is equal to zero.
Let's first find the slope of the line, which represents the rate of change of the number of automobiles per year:
slope = (change in number of automobiles) / (change in number of years)
slope = (2420 - 1890) / (2020 - 2015) = 106 automobiles per year
Now we can use the point-slope form of a linear equation to find the y-intercept:
y - y1 = m(x - x1)
where y1 is the value of the dependent variable when the independent variable is x1. In this case, x1 = 2015, y1 = 1890, and m = 106 (the slope we just calculated).
y - 1890 = 106(x - 2015)
To find the y-intercept, we can set x = 0:
y - 1890 = 106(0 - 2015)
y - 1890 = -213,290
y = 211,400

A) Find an equation for the line perpendicular to the tangent line to the curve y=x^3-4x+6 at the point (2,6)
-The equation is y=
b) What is the smallest slope on the curve? At what point on the curve does the curve have this slope?
-The smallest slope on the curve is
-The curve has the smallest slope at the point
c) Find equations for the tangent lines to the curve at the points where the slope of the curve is 8.
Answer:
f(x) = x³ - 4x + 6
f'(x) = 3x² - 4
a) f'(2) = 3(2²) - 4 = 12 - 4 = 8
6 = 8(2) + b
6 = 16 + b
b = -10
y = 8x - 10
b) 3x² - 4 = 0
3x² = 4, so x = ±2/√3 = ±(2/3)√3
= ±1.1547
f(-(2/3)√3) = 9.0792
f((2/3)√3) = 2.9208
c) 3x² - 4 = 8
3x² = 12
x² = 4, so x = ±2
f(-2) = (-2)³ - 4(-2) + 6 = -8 + 8 + 6 = 6
6 = -2(8) + b
6 = -16 + b
b = 22
y = 8x + 22
f(2) = 6
y = 8x - 10
The equation perpendicular to the tangent is y = -1/8x + 25/4
-The smallest slope on the curve is 2.92
The curve has the smallest slope at the point (1.15, 2.92)
The equations at tangent points are y = 8x + 16 and y = 8x - 16
Finding the equation perpendicular to the tangentFrom the question, we have the following parameters that can be used in our computation:
y = x³ - 4x + 6
Differentiate
So, we have
f'(x) = 3x² - 4
The point is (2, 6)
So, we have
f'(2) = 3(2)² - 4
f'(2) = 8
The slope of the perpendicular line is
Slope = -1/8
So, we have
y = -1/8(x - 2) + 6
y = -1/8x + 25/4
The smallest slope on the curveWe have
f'(x) = 3x² - 4
Set to 0
3x² - 4 = 0
Solve for x
x = √[4/3]
x = 1.15
So, we have
Smallest slope = (√[4/3])³ - 4(√[4/3]) + 6
Smallest slope = 2.92
So, the smallest slope is 2.92 at (1.15, 2.92)
The equation of the tangent lineHere, we set f'(x) to 8
3x² - 4 = 8
Solve for x
x = ±2
Calculate y at x = ±2
y = (-2)³ - 4(-2) + 6 = 6: (-2, 0)
y = (2)³ - 4(2) + 6 = 6: (2, 0)
The equations at these points are
y = 8x + 16
y = 8x - 16

find the circumference and the area of a circle with diameter of 6 ft
use 3.14
Answer:
Step-by-step explanation:he equation for circumference is:
c=2%28pi%29r
The equation for area is:
a=%28pi%29r%5E2
First, we'll find the circumference.
The 'r' in the equation stands for radius. The radius of a circle is half of its diameter, so the circle's radius is half of 6--3 inches.
So, we can substitute 3 in for 'r' and 3.14 in for pi
c=2%28pi%29r
c=2%2A3.14%2A3
Then, we can simply multiply.
c=2%2A3.14%2A3
c=18.84
Therefore, the circumference of the circle is 18.84
Next, we'll find the circle's area.
Again, we can substitute 3 in for 'r' and 3.14 in for pi
a=%28pi%29r%5E2
a=3.14%2A3%5E2
The, we'll square three and multiply.
a=3.14%2A3%5E2
a=3.14%2A9
a=28.26
Therefore, the circumference is 18.84 and the area is 28.26.
