Answer:
Perimeter = 63.9 cm.
Area = 166.96 cm^2 to the nearest hundredth.
Step-by-step explanation:
The perimeter = 16+20.9+27 = 63.9 cm.
To find the area you can use Heron's Formula.
Area = √ [ s(s-a)(s-b)(s-c)] where s = the semi-perimeter and a, b and c are the lengths of the 3 sides.
s = 63.9 / 2 = 31.95.
Area of the triangle = √ (31.95(31.95-16)(31.95-20.9)(31.95-27)]
= 166.96 cm^2.

Mrs. Ashe is planning to take her study group on a field trip to an amusement park. The regular cost is $50 per person. There is a party special that costs $35 per person with an additional $300 fee for a private room where students can eat lunch. Mrs. Ashe is trying to decide if she should use the regular price or the party special.
Part 1:
A) Write an equation in slope-intercept form (y=mx+b) to show the total cost of the regular price with x people, where x = number of students in the study group and y = the total cost. (10 points)
B) Write an equation in slope-intercept form (y=mx+b) to show the total cost of the party special with x people, where x = number of students in the study group and y = the total cost. (10 points)
Answer:
a) y = 50x + 0
b) y = 35x + 300
Step-by-step explanation:
a) The price is $50 (per person), so you multiply 50 by the number of people going (which is x).
b) The price is $35 dollars (per person), so you multiply 35 by the number of people (which again would be x). There is also an extra cost of $300.
Hope this helps! :)
if y varies directly as x, find the constant of variation if y= 32 when x= 8

D) {-2, -1, 0, 1, 2
Hello! Remember you have to write complete questions in order to get good and exact answers. Here you forgot to write the relation so I could help you providing my own relation.
Remember that for any relation, we have a set [tex]A[/tex] that matches the the domain (also called the set of inputs) of the function and the set [tex]B[/tex] that contains the range (also called the set of outputs).
Suppose our relation is:
[tex]y=-10+x \\ \\ For \ x=1,2,3,4,5[/tex]
So the x-values represents the set A and the y-values the set B. Therefore, by evaluating the x-values into our relation we get:
[tex]\text{If x=1} \\ \\ y=-10+1=-9 \\ \\ \\ \text{If x=2} \\ \\ y=-10+2=-8 \\ \\ \\ \text{If x=3} \\ \\ y=-10+3=-7 \\ \\ \\ \text{If x=4} \\ \\ y=-10+4=-6 \\ \\ \\ \text{If x=5} \\ \\ y=-10+5=-5[/tex]

y = log3(x) – 1
y = 3x - 3
y=-3(x - 1) + 3
y = log3(2x) - 2
Answer:
A
Step-by-step explanation:
y = log3(x) – 1
I don't know why but this is the correct answer.
[tex]y = \log_{3}x - 1[/tex] is the equation with real zeros corresponding to the x-intercepts of the graph.
How to find a function based on a graphAccording to the statement, we must find a function such that all values of [tex]x[/tex] so that [tex]y(x) = 0[/tex] and are the same of the graph. A quick approach consists in solving on each expression:
Expression A
[tex]\log_{3}x-1 = 0[/tex]
[tex]\log_{3}x = 1[/tex]
[tex]x = 3[/tex]
Expression B
[tex]3\cdot x - 3 = 0[/tex]
[tex]3\cdot x = 3[/tex]
[tex]x = 1[/tex]
Expression C[tex]-3\cdot (x-1) + 3 = 0[/tex]
[tex]-3\cdot x +6 = 0[/tex]
[tex]x = 2[/tex]
Expression D[tex]\log_{3}2x - 2 = 0[/tex]
[tex]\log_{3}2x = 2[/tex]
[tex]2\cdot x = 9[/tex]
[tex]x = \frac{9}{2}[/tex]
Hence, we conclude that [tex]y = \log_{3}x - 1[/tex] is the equation with real zeros corresponding to the x-intercepts of the graph. [tex]\blacksquare[/tex]

How much money must be deposited now in an
account paying 7.25% annual interest, compounded
quarterly, to have a balance of $1000 after 10
years?
Answer:
[tex]\$487.48[/tex]
Step-by-step explanation:
we know that
The compound interest formula is equal to
[tex]A=P(1+\frac{r}{n})^{nt}[/tex]
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
[tex]t=10\ years\\ A=\$1,000\\ r=7.25\%=7.25/100=0.0725\\n=4[/tex]
substitute in the formula above
[tex]1,000=P(1+\frac{0.0725}{4})^{4*10}[/tex]
[tex]1,000=P(\frac{4.0725}{4})^{40}[/tex]

[tex]P=\$487.48[/tex]
The government of the Republic of Lemon Island plans to transform their lemon-based
economy into a tourism-based economy. They develop the following model to predict the
long-term effect of this transformation for the size of their economy y:
dy
dt = (A − Be−t/5
)y; A, B > 0.
(a) Find the general solution y(t) for this equation.
(b) The Republic of Lemon Island has a current economic growth of 2% per year and
the government expects the transformation to cause this growth rate to triple in
the long term. Explain why values A = 0.06 and B = 0.04 are a good choice to
approximate this behaviour.
(c) Using A = 0.06 and B = 0.04, find the particular solution y(t) assuming that the
size of the economy of Lemon Island before the transformation is $50 000 000, and
that the transformation causes the size of the economy to shrink by $10 000 000 at
t = 0.
(d) The size of the economy of Lemon Island without the transformation can be mod-
eled using the same equation with parameters A = 0.02 and B = 0.
In which year after the transformation will the size of the transformed economy
surpass the size of the economy without the transformation?
(e) Elections on Lemon Island are in five years time. The Lemon Island Polling In-
stitute (LIPI) predicts that the current government will only be re-elected, if the
growth rate of the economy is, by then, at least 4%. According to the first model,
can the current government expect to be re-elected?
Step-by-step explanation:
dy/dt = (A − Be^(-t/5)) y
(a) Find the general solution by separating the variables and integrating.
dy / y = (A − Be^(-t/5)) dt
dy / y = [A + 5B (-⅕ e^(-t/5))] dt
ln |y| = At + 5B e^(-t/5) + C
y = e^(At + 5B e^(-t/5) + C)
y = Ce^(At + 5B e^(-t/5))
(b) As t approaches infinity, dy/dt approaches Ay. The rate of growth, A, is triple the initial rate of growth 0.02, so A = 0.06.
When t = 0, dy/dt = (A − B)y. The rate of growth, A−B, is 0.02. We know A = 0.06, so B = 0.04.
(c) Given that A = 0.06, B = 0.04, and y(0) = 50×10⁶ − 10×10⁶ = 40×10⁶:
40×10⁶ = Ce^(0.06(0) + 5(0.04) e^(-0/5))
40×10⁶ = Ce^(0.2)
C = 40×10⁶ e^(-0.2)
y = 40×10⁶ e^(-0.2) e^(0.06t + 0.2 e^(-t/5))
y = 40×10⁶ e^(-0.2 + 0.06t + 0.2 e^(-t/5))
(d) If A = 0.02 and B = 0, and there is no transformation (y(0) = 50×10⁶), then:
50×10⁶ = Ce^(0.02(0) + 0)
50×10⁶ = C
y = 50×10⁶ e^(0.02t)
Comparing to the answer from part (c):
40×10⁶ e^(-0.2 + 0.06t + 0.2 e^(-t/5)) = 50×10⁶ e^(0.02t)
e^(-0.2 + 0.04t + 0.2 e^(-t/5)) = 5/4
-0.2 + 0.04t + 0.2 e^(-t/5) = ln(5/4)
-5 + t + 5e^(-t/5) = 25 ln(5/4)
t + 5e^(-t/5) = 5 + 25 ln(5/4)
Solve with a calculator:
t = 9.886
The transformed economy surpasses the untransformed economy in the 10th year.
(e) In year t=5, the size of the transformed economy is:
y = 40×10⁶ e^(-0.2 + 0.06(5) + 0.2 e^(-5/5))
y = 47.6×10⁶
The percent growth is:
(47.6×10⁶ − 40×10⁶) / 40×10⁶ × 100% = 19%
The growth rate is greater than 4%, so the current government can expect to be reelected.
With similar triangle, the ratios of all three paris of corresponding sides are equal
Answer:
TRUE
Step-by-step explanation:
If this is a True/False question, the answer is True.
__
One of the ways to define triangle similarity is by the ratios of the sides. If the ratios of corresponding sides are the same, the triangles are similar.
Another way to define triangle similarity is by the angle measures. If corresponding angles are congruent, the triangles are similar.
Both conditions will be met by similar triangles.
A mug is 2/3 full. The mug contains 5/6 of a cup of water. Find the capacity of the mug.
We want to find the total capacity of the mug given that we know how much liquid there is in a 2/3 full mug.
We will find that the capacity of the mug is 1.25 cups.
We know that when the mug is 2/3 full, it has 5/6 cups.
Then if we define C as the total capacity of the mug, we can write:
(2/3)*C = 5/6 cups.
Now we can solve the above equation for C:
C = (3/2)*(5/6) cups = 1.25 cups.
The capacity of the mug is 1.25 cups.

The hypotenuse of a 30°-60°-90°
triangle has a length of 12 cm.
Which could be the length of a leg
of the triangle?
Answer: Below
Step-by-step explanation:
If you don't know Trigonometry, in a 30-60-90 triangle, the hypotenuse is always twice as long as the side opposite the 30° angle and the side opposite the 60° angle is √3 times as long as the side opposite the 30° angle.
So, since the hypotenuse has length 12 cm,
side opposite 30° angle (shorter leg) = 6 cm
side opposite 60° angle (longer leg) = 6√3 cm
The possible lengths of the legs are 6 and 6√3
How to determine the length of a leg?The triangle is given as:
30-60-90 triangle
And we have:
Hypotenuse = 12 cm
A 30-60-90 triangle is a unique triangle with the following parameters
Opposite = Hypotenuse/2
Adjacent = Hypotenuse/2 * √3
So, we have:
Opposite = 12/2
Adjacent = 12/2 * √3
Opposite = 6
Adjacent = 6√3
Hence, the possible lengths of the legs are 6 and 6√3

Which expression is equivalent to the following complex fraction?
2-1/y divided by 3+1/y
Answer: 2-1 / y times y/ 3+1
Step-by-step explanation:
In dividing fractions, it is possible to change the sign to multiplication sign by swapping positions of the numerator and denominator.
For example given,
a/b divided by c/d,
We can write this as
a/b times d/c
To simplify the given complex fraction [tex]\(\frac{{2 - \frac{1}{y}}}{{3 + \frac{1}{y}}}\),[/tex]we'll first rationalize the fractions in the numerator and denominator.
For the numerator:
[tex]\[2 - \frac{1}{y} = \frac{2y}{y} - \frac{1}{y} = \frac{2y - 1}{y}\][/tex]
For the denominator:
[tex]\[3 + \frac{1}{y} = \frac{3y}{y} + \frac{1}{y} = \frac{3y + 1}{y}\][/tex]
So, the original complex fraction becomes:
[tex]\[\frac{\frac{2y - 1}{y}}{\frac{3y + 1}{y}} = \frac{2y - 1}{3y + 1}\][/tex]
Therefore, the equivalent expression to the given complex fraction is option d. (2y-1)(3y+1).

A town has a population of 5000 and
grows at 2% every year. What will be the
population after 5 years, to the nearest
whole number?
Final answer:
To calculate the population after 5 years at a 2% growth rate, you apply the formula for exponential growth, resulting in an estimated population of 5512 to the nearest whole number.
Explanation:
To calculate the population of a town after 5 years with a 2% annual growth rate, you would use the formula for exponential growth. In this case, the initial population is 5000 and the growth rate is 0.02 (2%). The population after n years is given by the formula P(n) = P(0) × (1 + r)ⁿ, where:
P(0) is the initial population,r is the growth rate,and n is the number of years.After 5 years, the formula will look like this:
P(5) = 5000 × (1 + 0.02)⁵
Calculating the above:
P(5) = 5000 × (1.02)⁵P(5) = 5000 × 1.10408P(5) = 5512.41To the nearest whole number, the population of the town after 5 years will be 5512.

As x approaches ∞, which statement is correct?
A) The linear function will eventually exceed the exponential function.
B) The exponential function will eventually exceed the linear function.
C) The exponential function will only exceed the linear function if it has a greater growth factor.
D) The linear function will only exceed the exponential function if it has a greater common difference.
Answer:
B
Step-by-step explanation:
This is very simple if we understand a point of linear and exponential functions.
First of all, a linear growing function increases.
An exponential growing function increases as well.
But, linear function, no matter what the slope is, grows at a CONSTANT RATE. But,
Exponential function grows at a COMPOUND RATE.
So, if there are 2 functions, linear and exponential, the exponential will always exceed the linear, AT SOME POINT EVENTUALLY because of the growth factor (no matter growth factor of linear and exponential -- whatever they are).
So,
B is the correct answer.
Growth factor of each (both) doesn't matter. Exponential will always win!
Answer:
b
Step-by-step explanation:
The exponential function will always exceed the linear function.A quantity increasing exponentially eventually exceeds a quantity increasing linearly.
