Step-by-step explanation:
identify the function shown in the graph
Answer:
C
Step-by-step explanation:
The line crosses the y-axis at 3, and has a slope of -1/5. You can use the formula y=mx+b where m represents the slope and b is the point at which the line crosses the y-axis.
Consider this function.
F(x) = x - 4 + 6
If the domain is restricted to the portion of the graph with a positive slope, how are the domain and range of the function and
its inverse related?
Since the domain of the original function is limited to x 6, the range of the inverse function is y s6.
Since the domain of the original function is limited to x> 4. the range of the inverse function is ys 1.
Since the range of the original function is limited to y > 6, the domain of the inverse function is x 26
Since the range of the original function is limited to y 4, the domain of the inverse function is x 1.
Answer:
Since the range of the original function is limited to y 6, the domain of the inverse function is x ≥ 6.
Step-by-step explanation:
The answer is the statement Since the range of the original function is limited to y > 6, the domain of the inverse function is x ≥ 6.
What is the domain of an inverse function?The domain of the inverse of a relation is the same as the range of the original relation. In other words, the y-values of the relation are the x-values of the inverse.
What is a positive slope?The positive slope definition tells us that a line with a positive slope is one where the right side of the line is higher than the left side of the line.
So, by the definition given above, we see that
if the range of the original function is limited to y > 6, the domain of the inverse function is x >= 6.

Oxidation state of O in H3O+
Answer:
Step-by-step explanation:
The oxidation state of O in H₃O⁺ is -2
From the question, the given ion is H3O+.
This can be written properly as H₃O⁺
To determine the oxidation state of O (that is Oxygen) in H₃O⁺,
The oxidation state of H (Hydrogen) here is +1
∴ We can form the equation
(+1 × 3) + O = +1
(NOTE: The expression is equated to +1 because the overall charge on the given ion is +1)
Then, we have
+3 + O = +1
Now, subtract 3 from both sides
+3 -3 + O = +1 -3
∴ O = -2
Hence, the oxidation state of O in H₃O⁺ is -2

P(not a king|king) =
Answer:
48/51
Step-by-step explanation:
The probability of not choosing a king after you've chosen the first king is 48/51 since there are 48 cards in the deck that are not kings and there are 51 cards left in the deck, including king cards.
Answer: Their are 4 kings in a deck of cards, so the answer would be P( Cards that aren't Kings/Total cards) so the probability is .92 or 92%.
17. A bottlenose dolphin jumps out of the water. The path the dolphin Travels can be
modeled by h = -0.2d2 + 2d, where h represents the height of the dolphin and d
represents horizontal distance.
a. What is the maximum height the dolphin reaches?
b. How far did the dolphin jump?
The maximum height that the dolphin reaches is 5 units, which occurs at a horizontal distance of 5 units. The dolphin's total horizontal jump distance is 10 units.
Explanation:The maximum height the dolphin reaches (the vertex of the parabola) is found by the formula -b/(2a) for the maximum or minimum of a parabola ax^2 + bx + c. In your equation, a = -0.2 and b = 2. Therefore, the horizontal distance, d, at the maximum height is d = -b/(2a) = -2/(-0.4) = 5 units. Substituting d = 5 into the original equation gives h = -0.2*5^2 + 2*5 = 5 units. Thus, the maximum height the dolphin reaches is 5 units.
The dolphin's horizontal distance (the 'd' value when h = 0) specifies the full length of the jump. Solving the equation -0.2*d^2 + 2*d = 0 gives d = 0 (the start of the jump) and d = 10 (the end of the jump). Thus, the dolphin jumped 10 units horizontally.

#SPJ3
The maximum height reached by the dolphin is 5 meters, and it jumps a horizontal distance of 10 meters. This is determined by analyzing the quadratic equation for maximum height and the point where the dolphin returns to the water surface.
To determine the maximum height (h) the dolphin reaches, we need to analyze the given quadratic equation h = -0.2d² + 2d. Because the coefficient of d² is negative, the parabola opens downward, indicating that the vertex of the parabola will give us the maximum height. The vertex of a parabola in the form of h = ad² + bd + c is given by the formula d = -b/(2a). In this case, a = -0.2 and b = 2, so the horizontal distance (d) at the vertex is d = -2/(2 × (-0.2)) = 5 meters. Plugging this back into the equation, we get h = -0.2(5)² + 2(5) = -0.2(25) + 10 = -5 + 10 = 5 meters.
So, the maximum height reached by the dolphin is 5 meters.
The dolphin jumps until it returns to the water surface, which means the height h becomes 0. We solve the quadratic equation 0 = -0.2d² + 2d by factoring out d: 0 = d(-0.2d + 2). This gives us two solutions: d = 0 (the starting point) and -0.2d + 2 = 0 which leads to d = 10.
Therefore, the dolphin jumped a horizontal distance of 10 meters

Alice buys a book for £19.80
A year later she sells the book for £12.87
Calculate the percentage decrease in the value of the book.
Answer:35%
Step-by-step explanation:
The percentage decrease in the value of the book is 35%.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Cost of the book = £19.80
Selling price of the book = £12.87
The percentage decrease in the value of the book.
= (19.80 - 12.87)/19.80 x 100
= 6.93/19.80 x 100
= 35%
Thus,
The percentage decrease is 35%.

The sum of two numbers is 14. The first number is 2/5 of the second number. What are the numbers?
Answer:
4 and 10
Step-by-step explanation:
To solve this problem, we need to find all the numbers between 1 and 13 that have a sum of 14. The list is shown below:
1 + 13, 2 + 12, 3 + 11, 4 + 10, 5 + 9, 6 + 8, 7 + 7
Now we must figure out which set of numbers include one number that is 2/5 of the value of the other. We can do that by turning the sets of numbers into fractions as shown below:
[tex]\frac{1}{13}\neq \frac{2}{5}[/tex]
[tex]\frac{2}{12}\neq \frac{2}{5}[/tex]
[tex]\frac{3}{11}\neq \frac{2}{5}[/tex]
[tex]\frac{4}{10}= \frac{2}{5}[/tex] (answer)
[tex]\frac{5}{9}\neq \frac{2}{5}[/tex]
[tex]\frac{6}{8}\neq \frac{2}{5}[/tex]
[tex]\frac{7}{7}\neq \frac{2}{5}[/tex]
The first number is 4, and the second number is 10, and their sum is indeed 14, as given in the problem.
Let's call the first number "x" and the second number "y." According to the information given:
The sum of the two numbers is 14, so we can write the equation:
x + y = 14
The first number (x) is 2/5 of the second number (y), which can be expressed as:
x = (2/5)y
Now, we can solve this system of equations using substitution. First, we'll substitute the expression for x from the second equation into the first equation:
(2/5)y + y = 14
To make the equation easier to solve, we can get rid of the fraction by multiplying both sides of the equation by 5 (the denominator of 2/5):
5(2/5)y + 5y = 5 * 14
This simplifies to:
2y + 5y = 70
Now, combine like terms:
7y = 70
To solve for y, divide both sides by 7:
y = 70 / 7
y = 10
Now that we've found the value of y, we can find the value of x using the second equation:
x = (2/5)y
x = (2/5) * 10
x = 4
So, the two numbers are:
x = 4
y = 10

Alice and Briana each participate in a 5 kilometer race. Alice's distance covered, in kilometers, after t minutes can be modeled by the equation a(t) =
Answer:
a. Alice
b. Briana
c. 0.51 minutes
Step-by-step explanation:
a. Alice formula is valid for any t > 0 minutes, but Briana formula is only valid for
2t - 1 > 0
2t > 1
t > 1/2 minutes
b. They finish when their covered distance is equal to 5 kilometers. For Alice:
t/4 = 5
t = 5*4 = 20 minutes
For Briana:
√(2t - 1) = 5
2t - 1 = 5²
2t = 25 + 1
t = 26/2
t = 13 minutes
c. They are side by side when they have covered the same distance, that is:
t/4 = √(2t - 1)
(t/4)² = 2t - 1
t²/16 = 2t - 1
t² = 16*(2t - 1)
t² = 32t - 16
t² - 32t + 16 = 0
Using quadratic formula:
[tex]t = \frac{-b \pm \sqrt{b^2 - 4(a)(c)}}{2(a)} [/tex]
[tex]t = \frac{32 \pm \sqrt{-32^2 - 4(1)(16)}}{2(1)} [/tex]
[tex]t = \frac{32 \pm 30.98}{2} [/tex]
[tex]t_1 = \frac{32 + 30.98}{2} [/tex]
[tex]t_1 = 31.49 [/tex]
[tex]t_2 = \frac{32 - 30.98}{2} [/tex]
[tex]t_2 = 0.51 [/tex]
Only the second answer has sense for this problem because the race already finished before they spent 31.49 minutes in it.
Answer:
a) Alice starts first, b) Briana gets the finish line first, c) [tex]t \approx 0.509\,min[/tex]
Step-by-step explanation:
a) Alice starts first, since binomial inside the squared root is equal to zero when [tex]t = \frac{1}{2}\,min[/tex], whereas Alice begins at [tex]t = 0\,min[/tex].
b) The instant when each competitor reach finish line is:
Alice
[tex]5\,km = \frac{t}{4}[/tex]
[tex]t = 20\,min[/tex]
Briana
[tex]5\,km = \sqrt{2\cdot t - 1}[/tex]
[tex]25\,km^{2} = 2\cdot t - 1[/tex]
[tex]t = 13\,min[/tex]
Briana gets the finish line first.
c) Alice and Briana are side by side when [tex]a(t) = b(t)[/tex]. Then:
[tex]\frac{t}{4} = \sqrt{2\cdot t - 1}[/tex]
[tex]\frac{t^{2}}{16} = 2\cdot t - 1[/tex]
[tex]t^{2} - 32\cdot t + 16 = 0[/tex]
The roots of the second order polynomial are:
[tex]t_{1} \approx 31.492\,min[/tex] and [tex]t_{2} \approx 0.509\,min[/tex]
Just the second roots makes sense, as they must be side by side at one instant before getting the finish line.

Given P(A) = 0.6, P(B) = 0.45 and P(AorB) = 0.66 , find the value of P(A and B) , rounding to the nearest thousandth, if necessary .
Answer:
P(A and B) = P(A) + P(B) - P(A or B)
= 0.6 + 0.45 - 0.66
= 0.39
The value of P(A AND B), given the probabilities of P(A), P(B), and P(A OR B), is found to be 0.39.
To find the probability of both events A and B occurring, we use the formula for the probability of the union of two events, which is P(A OR B) = P(A) + P(B) \'96 P(A AND B). We rearrange this formula to find P(A AND B) by subtracting P(A) and P(B) from P(A OR B):
P(A AND B) = P(A) + P(B) \'96 P(A OR B)
Substituting the given values:
P(A AND B) = 0.6 + 0.45 \'96 0.66 = 0.39
So, the probability of A and B occurring together, P(A AND B), is 0.39, which rounds to the nearest thousandth as required.

Tree
What is the smallest length of rope that Ryan could buy which would stretch from one tree to the other?
Answer: 25 meters.
Step-by-step explanation:
The missing figure is attached.
Draw a Right triangle as the one shown in the second picture, where "a" is the smallest length of rope (in meters) that Ryan could buy, which would stretch from one tree to the other tree.
You need to use the Pythagoream Theorem:
[tex]a^2=b^2+c^2[/tex]
Where "a" is the hypotenuse and "b" are "c" are the legs of the Right triangle.
In this case you can identify that:
[tex]b=25-10=15\\\\c=20[/tex]
Knowing those values, you can susbtitute into [tex]a^2=b^2+c^2[/tex] and then solve for "a" in order to find its value.
You get:
[tex]a^2=15^2+20^2\\\\a=\sqrt{15^2+20^2}\\\\a=25[/tex]
Evaluate the expression when b=-5.

Step-by-step explanation:
This is a substitution question
So we will have to solve by substituting the given value into the equation
So let's solve
b^2-8b-6
And b is given to be-5
So let's substitute
(-5)^2-8(-5)-6
25+40-6
65-6
