We can simplify the given expression:
((a⁵*a)/(a⁻³) )⁻¹
To get:
a⁻⁹
How to simplify the expression?There are some properties we need to use:
xᵃ*xᵇ = xᵃ⁺ᵇ(xᵃ)ᵇ = xᵃ*ᵇx⁻ᵃ = 1/xᵃOur expression is:
((a⁵*a)/(a⁻³) )⁻¹
First we can simplify the numerator:
a⁵*a = a⁵⁺¹ = a⁶
((a⁶)/(a⁻³) )⁻¹
Using the third property we can also rewrite the denominator:
(1/a⁻³) = a³
Replacing that we get:
((a⁶)/(a⁻³) )⁻¹ = ((a⁶)*a³ )⁻¹ = (a⁶⁺³)⁻¹ = a⁻⁹

Find the value of f(3) for each of the following:
1. f(x) = 7 – 8x 2. f(a) = -5(a – 2)
3. f(h) = - h/72 4. f(m) = m(m + 4)
Answer:
Step-by-step explanation:
1) f(x) = 7 - 8x²
f(3) = 7 - 8*3²
= 7 - 8*9
= 7 - 72
f(3) = -65
2) f(a) = -5(a-2)
f(3) = -5(3 -2) = -5 * 1 = -5
\(3)f(h) =\dfrac{-h}{72}\\\\\\f(3)=\dfrac{-3}{72}=\dfrac{-1}{24}\)
4) f(m) = m(m +4)
f(3) = 3*(3+4) = 3 * 7 = 21
An extremely large sink hole has opened up in a field just outside of the city limits. It is difficult to measure across the sink hole without falling in so you use congruent triangles. You have one piece of rope that is 50 ft. long and another that is 70 ft. long. You pick a point A on one side of the sink hole and B on the other side. You tie a rope to each spot and pull the rope out diagonally back away from the sink hole so that the other ends of the two ropes meet at point C. Then you recreate the same triangle by using the distance from AC and BC and creating new segments CE and CD. The distance DE is 52.2 ft.
a. What type of triangles have you created?
b. How do you know the triangles are congruent?
c. How far across is the sink hole?
d. What is the perimeter of the triangle ABC?
A) The type of triangles are congruent triangles
B) By the use of SAS Congruency Postulate
C) The distance across for the sink hole is: 52.2 ft
D) The perimeter of triangle ABC is: 172.2 feet.
How to solve congruent triangles?A) Congruent triangles are defined as the triangles created because of the phrasing "you recreate the same triangle" mentioned in the instructions. Congruent triangles are basically identical carbon copies of each other.
B) If we knew the measure of angle ACB, and then mad use of it to form angle ECD, then we would have enough information to know that triangle ACB was congruent to triangle ECD. Therefore, it would be useful to do the SAS (side angle side) congruence rule.
C) We know that:
AB = ED = 52.2
AB is the distance across the sink hole. Thus, it is 52.2 feet
D) AB = 52.2
BC = 70
AC = 50
Thus:
Perimeter of triangle ABC = AB + BC + AC
Perimeter of triangle ABC = 52.2 + 70 + 50
Perimeter of triangle ABC = 122.2 + 50
Perimeter of triangle ABC = 172.2
The perimeter of triangle ABC is 172.2 feet.

Raul tossed a coin and spin a spinner with three equal sections. Based upon the results, what is the probability of tossing a tail and spinning a 2?
F. 1/10
G. 1/9
H. 1/8
J. 3/20
The experimental probability of tossing a tail and spinning a 2 is given by: Option H: 1/8
What is experimental probability?Experimental probability calculates the probability of some event from the results of experiments.
For an event E, we get the experimental probability of that event
\(P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}\)
where, \(P_e(E)\) is denoting experimental probability of occurrence of E.
For this case, the table is missing, the results recorded were:
Toss Spin Frequency
Head 1 2
Head 2 6
Head 3 7
Tail 1 7
Tail 2 5
Tail 3 13
That means total number of times experiment was done was: 2+6+7+7+5+13=40
Let we take E = event of tossing a tail and spinning a 2
Thus, from the table, we see that E occurred 5 times.
Thus, based on this, the experimental probability of occurrence of E is:
\(P_e(E) = \dfrac{5}{40} = \dfrac{1}{8}\) (option H)

Answer: 5
Step-by-step explanation: To solve f(x), g(x), or f(g(x)) problems, we place the value of x in the functions with the value that we are given. This value will be f(g(5)) or g(3) or f(27). We plug in the number in the parentheses.
In this problem, we have to first plugin 5 to g(x) then plug g(5) into f(x).
First, we do g(5)=sqrt((5^2)+2). This gives us 3. Then we plug in 3 which is g(5) into f(x). This gives us f(g(5)) or f(3)=sqrt((3^3)-2) which is 5.

Answer:
499.338 feet
Step-by-step explanation:
You want to know the distance traveled by an object in 25 seconds when its velocity is described by 20+5cos(t) feet per second.
DistanceThe distance an object travels is the integral of its velocity. For the given velocity and time period, the distance is ...
\(\displaystyle d=\int_0^{25}{v(t)}\,dt=\int_0^{25}{(20+5\cos(t))}\,dt=(20t+5\sin(t))|_0^{25}\\\\d=500+5\sin(25)\approx\boxed{499.338\quad\text{feet}}\)
The distance traveled in 25 seconds is 499.33 feet.
It is required to find the distance traveled in 25 seconds.
What is distance?The distance of an object can be defined as the complete path travelled by an object .Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Given:
We have to find the distance , we will integrate v(t) from 0 to 25 second.
Consider an object traveling at constant velocity v = k. Then, each second, it travels k feet, so after t seconds, the distance traveled is k*t.
Now, suppose its speed increases by 1 feet/sec . So, estimate for distance traveled after t seconds is
1 + 2 + 3 + 4 + ... + t = t(t+1)/2, or approximately 1/2 t^2.
According to given question we have
Given a velocity function v, the distance s is figured by taking the integral. In this case,
v = 20 + 5 cos(t)
s = 20t + 5 sin(t) from 0 to 25
= s(45)-s(0)
s(0) = 0
so, the distance is
s(25) = 20*25 + 5sin(25)
= 500 -0.661
=499.33 feet.
Therefore, the distance traveled in 25 seconds is 499.33 feet.

An ice cream cone with a 2cm radius has a volume of 75.36 cubic cm how tall is the ice cream cone
Step-by-step explanation:
reading the question thoroughly, we find out that volume (V) and radius (r) of the cone is given, and we just have to find out the length (h) of the cone
V = πr²h/3
Putting the given values in place,
V = 75.36 cm³
V = 75.36 cm³r = 2 cm
V = 75.36 cm³r = 2 cmπ = 3.14
Now, since we calculating for h, we can interpret the formula in the terms of h, i.e.
h = 3V/(πr²)
h = 3×75.36/(3.14×2²)
h = 226.08/12.56
h = 18 cm
Thus, the height of the ice cream cone is 18cm

What is the surface area of the triangular prism?
The surface area of the triangular prism is 608 cm².
What is surface area and volume? Surface area and volume are two measurements of three-dimensional objects. Surface area is the total area of the object’s exposed sides, while volume is the amount of space that the object occupies. Surface area is typically measured in square units, such as inches or centimeters, while volume is measured in cubic units, such as cubic inches or cubic centimeters.The primary difference between surface area and volume is that surface area measures the area of the exposed surfaces of an object, while volume measures the amount of space within the object. Volume is the total amount of space inside the object, while surface area is the total area of the exposed faces of the object. For example, a cube has six faces, and each of those faces has an area. The total of all six faces is the surface area of the cube, while the volume is the amount of internal space inside the cube.Given,
base of triangle = 12 cm
height of triangle = 8 cm
length of triangle = 10 + 10 + 12 = 32 cm
Width of the triangle = 16 cm
Area of the rectangle = l x b = 32 x 16 = 512 cm²
Area of triangle = 1/2 x 12 x 8 = 48 cm²
There are 2 triangle, so 48 + 48 = 96 cm²
Add all these values, 512 + 96 = 608 cm²

Explain about the triangular prism?Having two triangular bases and three rectangular sides, a triangular prism is a type of polyhedron. It is a three-dimensional object with two base faces and three side faces that are joined by edges.
There are 6 vertices, 5 edges, and 5 faces on it. The other 3 faces have a rectangle-like shape, while the 2 bases are structured like a triangle. Camping tents, chocolate candies, roofs, etc. are a few instances of triangular prisms in the real world.
A solid object called a prism has plane faces enclosing each of its four sides. Faces in a prism come in two different varieties. Bases are used to describe the top and bottom faces, which are identical.
12 cm is the triangle's base.
triangle's height is 8 cm.
Triangle's length is 32 cm (10 + 10 + 10 cm).
Triangle width is 16 cm.
The rectangle's area is 512 cm2 (l x b = 32 x 16).
Triangle area equals 1/2 x 12 x 8 = 48 cm2.
Two triangles are present, therefore 48 + 48 = 96 cm2.

Among the 2302 respondents, 272 said that they only play hockey. what percentage of respondents said that they only play hockey?
Answer:
(a) The exact value that is 33% of 2302 is 759.66.
(b) No, the result from part (a) could not be the actual number of adults who said that they play basketball.
(c) The actual number of adults who said that they play basketball is 760.
(d) 11.82% of respondents said that they only play hockey.
Step-by-step explanation:
We are given that a polling company reported that 33% of 2302 surveyed adults said that they play basketball.
(a) The exact value that is 33% of 2302 is given by;
\(33\% \text{ of } 2302\) = \(\frac{33}{100}\times 2302\)
= 759.66
(b) No, the result from part (a) could not be the actual number of adults who said that they play basketball because the value in part (a) is in fractions or in decimals and the number of people can't be in fractions. It must be a whole number.
(c) The actual number of adults who said that they play basketball is 760. {As 759.66 rounded to one decimal point}
(d) It is given that among the 2302 respondents, 272 said that they only play hockey.
Percentage of respondents who said that they only play hockey is given by;
= \(\frac{272}{2302}\times 100\) = 11.82% ≈ 12%
a) The exact value of \(33\)% of \(2302\) is,
\(=\frac{33}{100}\times 2302\)
\(=759.66\)
b) \(759.66\) is not the actual number of adults who said that they play football as the actual number should be a whole number and not a rational number with decimal values.
c) The actual number could be a rounded one i.e. \(760\).
d) Let \(272\) be \(x\)% of \(2302\).
\(\Rightarrow \frac{x}{100}\times 2302=272\\\Rightarrow x=\frac{272\times 100}{2302} \\\Rightarrow x=11.8158 \ or \ 11.82\)%
Therefore, \(11.82\)% of respondents said that they only play hockey.

Consider two coins, CH and CT . Suppose that coin CH has probability 0.6 of coming up heads and that coin CT has probability 0.3 of coming up heads. On each day, we will select one coin to flip and register the outcome. On the first day (day one), we will pick a coin at random (uniformly). On subsequent days, we will flip coin CH if the outcome the previous day was heads, and we will flip coin CT if the previous outcome was tails. Determine the probability that the coin flipped on the third day after the initial flip (i.e., on day four) is coin CH. State any independence assumptions you use. Explain.
Answer:
0.4305
Step-by-step explanation:
Let \(P(H_n)\) and \(P(T_n)\) be the probability of coming up head and tail respectively on day \(n\).
On day four, the coin CH will be salected iff there in head as outcome on the previous day, i.e. on the day three.
So, actually the probability of salection of coin CH on day four is probability of coming up head on day three, \(P(H_3)\).
On day 1, n=1:
As one coin is salected randomly from two coin, so, the probability of salection of one coin is 1/2=0.5.
\(P(H_1)\) is the probability of salection of coin CH and coming up head or salection of coin CT and coming up head when tossed.
So, \(P(H_1)=0.5\times 0.6 + 0.5\times0.3=0.45\).
As there is only two outcome on any day, head or tail, so
\(P(T_1)=1-P(H_1)=1-0.45=0.55\)
On day two, n=2:
The probability of salection of any coin depends on the outcpme of previous day, i.e
Probability of salection of coin CH and CT on day two are
\(P(H_1)=0.45\) and \(P(T_1)=0.55\) respectively.
So, \(P(H_2)=0.45\times 0.6 + 0.55\times0.3=0.435\).
As there is only two outcome on any day, head or tail, so
\(P(T_2)=1-P(H_2)=1-0.435=0.565\)
Similarly, on day three, n=3:
The required probability is \(P(H_3)\),
\(P(H_3)=P(H_2)\times0.6 + P(T_2)\times 0.3\)
\(\Rightarrow P(H_3)=0.435\times0.6 + 0.565\times 0.3=0.4305\)
Hence, the salection od coin CH on day four is 0.4305.

Step-by-step explanation:
Laila purchased a prepaid phone card for $25 . Long distance calls cost 24 cents a minute using this card. Laila used her card only once to make a long distance call. If the remaining credit on her card is $13.72 , how many minutes did her call last?
Answer:
The call lasted for 47 minutes.
Step-by-step explanation:
It is given that:
Value of prepaid card = $25
Cost per minute of long distance call = 24 cents = $0.24
Remaining credit = $13.72
Let,
x be the number of minutes
y be the remaining amount
y = 25 - 0.24x
13.72 = 25 - 0.24x
0.24x = 25 - 13.72
0.24x = 11.28
Dividing both sides by 0.24
\(\frac{0.24x}{0.24}=\frac{11.28}{0.24}\\x=47\)
Therefore,
The call lasted for 47 minutes.
