I own 1 mini fish and 2 giant fish each giantfish weighs 3 times as much as minfish. If my mini fish eats my two giantfish, then how many times more weight will my mini fish have now than before
Answer: 6 pounds
Step-by-step explanation:
Answer:
The mini fish would weigh 6 times its original amount hypothetically but if we were talking realistically then you would need more information to figure that out. But even then there's no way of determining the specific weight.

Based on the graph of the given limit of a function, the value for which [tex]\lim_{x \to a} g(x)[/tex] doesn't exist is equal to -3.
What is a limit?A limit can be defined as a numerical value which a function approaches (output) as the input value approaches other values. In Mathematics, limits are typically used to determine the following:
IntegralsDerivativesContinuityFor the right-hand limit, we have:
[tex]\lim_{x \to -3^{+}}[ -3 + 1] = -2[/tex]
For the right-hand limit, we have:
[tex]\lim_{x \to -3^{-}} [-3 - 1] = -4[/tex]
By critically observing the graph of the given limit of a function, we can logically deduce that -3 is the value for which [tex]\lim_{x \to a} g(x)[/tex] doesn't exist because the right-hand limit and left-hand limit are not the same (different).

Parallelogram JKLM shown below is going to be rotated 270° clockwise to create J'K'L'M'. Which rule describes this transformation? K M F. (x, y) = (-y, x)
G. (x, y) = (-x. -Y)
H. (x, y) = (y, -x)
J. (x,y) → (-x, y) c
Answer:
F. (x, y) = (-y, x)
Step-by-step explanation:
270º clockwise transformation:
The 270° clockwise transformation of a point (x,y) is:
(x,y) -> (-y,x)
Thus, as we just apply the rule in this conceptual question, the correct answer is given by:
F. (x, y) = (-y, x)

The 3 inside angles of a triangle need to equal 180 degrees.
Add the 3 together to equal 180:
X + 2x + x+ 14 = 180
Combine like terms:
4x + 14 = 180
Subtract 14 from both sides:
4x = 166
Divide both sides by 4
X = 41.5
Answer:
Fraction form: x = 83/2
Decimal form: x = 41.5
Step-by-step explanation:
The 3 angles inside the triangle will always add up to 180 degrees.
So that gives us the equation:
x + 14 + x + 2x = 180
Combine like terms:
4x + 14 = 180
Subtract on both sides:
4x = 166
Divide:
41.5

Answer:
We will split the trapezoid into right angle triangle and rectangle
Traingle with base 3cm and height 10 - 6 = 4cm
Area of traingle
= [tex]\frac{1}{2}*base *height = \frac{1}{2} * 3 * 4 = 6cm^{2}[/tex]
Area of rectangle with sides 6cm and 3cm
=[tex]6 * 3 = 18cm^{2}[/tex]
Therefore, area of the trapezoid
= [tex]6+18 = 24cm^{2}[/tex]
Area of the semi circle with radius 3/2 = 1.5cm
= [tex]\frac{1}{2}\pi r^{2} = \frac{1*\pi *1.5*1.5}{2} = 1.125\pi cm^{2}[/tex]
[tex]Total area = 24 + 1.125\pi =27.53cm^{2}[/tex]

if you divide the answer althrough by 2 you should get the above equation
9514 1404 393
Answer:
C: 2x+2y=-2
Step-by-step explanation:
The equation that makes the system have infinitely many solutions is one that is dependent on the given equation. The easiest way to make a dependent equation is to multiply the given equation by some constant.
Here, choice C has the original equation multiplied by 2, so it is dependent on the given equation.
x + y = -1 ⇒ 2(x + y) = 2(-1) ⇒ 2x + 2y = -2 . . . . matches choice C

If Samuel travels twenty kilometers north, fifty kilometers south, and forty kilometers west, what is the approximate magnitude of his total displacement, in kilometers? Find the solution by drawing a diagram. km
Answer:
108.75km
Step-by-step explanation:
please find attached the diagram
total displacement can be determined by using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
length of x =
20² + 40²
= 400 + 1600
2000
square root of 2000
= 44.72km
length of y
40² + 50²
1600 + 2500 = 4100
square root of 4100
64.03km
total displacement = 44.72 + 64.03 = 108.75

A soccer ball is kicked from the top of a 64 ft building into the air at an initial speed of 48 ft/sec. Its flight as a functions of time can be modeled by: h(t)=−16t2+48t+64. After how many seconds, will the soccer ball hit the ground (h=0)?
Answer:
t = 4 seconds
Step-by-step explanation:
The height of a soccer ball as a function of time is given by :
[tex]h(t)=-16t^2+48t+64[/tex]
We need to find the time when the ball hit the ground i.e. h = 0
Put h = 0 in above equation. So,
[tex]-16t^2+48t+64=0\\\\16(-t^2+3t+4)=0\\\\-t^2+3t+4=0[/tex]
It is a quadratic equation such that,
t = -1 s and t = 4 s
Neglecting -1 s, the ball will hit the ground after 4 seconds.

A) What is the probability that when using an unfair coin, with a head = 1/5 and a tail =4/5:
1) you get the third head on the 5th toss?
2) that you get the expected number of heads you will get when you toss the coin six times?
B) What is the probability that when using an unfair coin, with a head = 3/5 and a tail =2/5:
1) If you toss the coin 5 times, what is the probability that you will get 2heads and 3 tails?
2) What is the expected number of heads you will get when you toss the coin six times?
Answer:
A)
1) 0.03072 = 3.072% probability you get the third head on the 5th toss.
2) The expected number of heads you will get when you toss the coin six times is 1.2.
B)
1) 0.2304 = 23.04% probability that you will get 2 heads and 3 tails.
2) The expected number of heads you will get when you toss the coin six times is 3.6.
Step-by-step explanation:
For each coin, there are only two possible outcomes. Either it is tails, or it is heads. The probability of a toss being heads or tails is independent of any other toss. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
The expected value of the binomial distribution is E(X) = np.
Item A:
1) you get the third head on the 5th toss?
1/5 probability of heads, so [tex]p = \frac{1}{5} = 0.2[/tex]
This is two heads on 4 tosses(P(X = 2) when n = 4) and then head on the 5th toss, with 0.2 probability. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{4,2}.(0.2)^{2}.(0.8)^{2} = 0.1536[/tex]
0.1536*0.2 = 0.03072
0.03072 = 3.072% probability you get the third head on the 5th toss.
2) that you get the expected number of heads you will get when you toss the coin six times?
Six tosses means that [tex]n = 6[/tex]. So
[tex]E(X) = np = 6*0.2 = 1.2[/tex]
The expected number of heads you will get when you toss the coin six times is 1.2.
Question B:
3/5 probability of heads, which means that [tex]p = \frac{3}{5} = 0.6[/tex]
1) If you toss the coin 5 times, what is the probability that you will get 2heads and 3 tails?
This is P(X = 2) when n = 5. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{5,2}.(0.6)^{2}.(0.4)^{3} = 0.2304[/tex]
0.2304 = 23.04% probability that you will get 2 heads and 3 tails.
2) What is the expected number of heads you will get when you toss the coin six times?
Six times means that [tex]n = 6[/tex]. So
[tex]E(X) = np = 6(0.6) = 3.6[/tex]
The expected number of heads you will get when you toss the coin six times is 3.6.
A rectangle's length is twice its width.
If its perimeter is 288 cm, find the length.
Answer:
96cm

2. Which sequence of transformations takes the graph of y = k(x) to the graph of
y=-k(x + 1)?
A. Translate 1 to the right, reflect over the x-axis, then scale vertically by a factor of
B. Translate 1 to the left, scale vertically by , then reflect over the x-axis.
C. Translate left by , then translate up 1.
D. Scale vertically by z, reflect over the y-axis, then translate up 1.
Answer:
A. Translate 1 to the right, reflect over the x-axis, then scale vertically by a factor of 1
Step-by-step explanation:
Initially:
We have the function [tex]y = k(x)[/tex]
k(x + 1)
To translate a function k(x) a units to the left, we find k(x + a).
Thus, k(x+1) is the translation of k(x) 1 unit to the left.
-k(x+1)
Multiplying a function by a negative constant is the same as reflecting it over the x-axis, and then scaling it vertically by a factor of the constant.
Thus:
The answer is given by option A:
A. Translate 1 to the right, reflect over the x-axis, then scale vertically by a factor of 1
