Answer:
200
Step-by-step explanation:
Given Arithmetic sequence is: 26, 28, 30,...
First term a = 26
Common Difference d = 2
n = 88
[tex] \because t_n=a +(n-1) d \\ \therefore \: t_{88}=26 +(88-1) \times 2 \\ \therefore \: t_{88}=26 +87 \times 2 \\ \therefore \: t_{88}=26 +174 \\ \huge \red{ \boxed{ \therefore \: t_{88}=200}} \\ [/tex]
The 88th term of the arithmetic sequence 26, 28, 30,... is 200.
Explanation:The given sequence is an arithmetic sequence, where each term is obtained by adding 2 to the previous term. The first term of the sequence is 26, and the common difference is 2.
To find the 88th term of the sequence, we can use the formula for the nth term of an arithmetic sequence: an = a1 + (n - 1)d, where an is the nth term, a1 is the first term, n is the term number, and d is the common difference.
Plugging in the given values: an = 26 + (88 - 1)2 = 26 + 87*2 = 26 + 174 = 200.

Curtis rides his bike 9 miles one way then turns around and rides back. On the return trip, his speed is increased 20% because the wind is at his back. Let s be his speed in miles per hour riding against the wind. What is an expression that represents his total time in hours riding there and back?
Answer:
The expression that represents his total time is given by "t = 7.5/s" where s is his speed against the wind.
Step-by-step explanation:
In order to solve this problem we will assign a variable to Curtis speed on the first leg of the trip, this will be called "s". Since the speed on the first part is "s" and the speed on the second part is 20% higher, then the speed on the second part is "1.2s". Each leg of the course is 9 miles long, therefore the time it took to go each way is given by:
time = distance/speed
First part:
t1 = 9/s
Second part:
t2 = 9/1.2s = 7.5/s
The expression for the whole course is the sum of each, so we have:
t = t1 + t2
t = 9/s + 7.5/s
t = (9 + 7.5)/s = (16.5)/s

Find all real square roots of 64
Answer:
8 and -8
Step-by-step explanation:
The definition of a square root is 'a number which produces a specified quantity when multiplied by itself.' Though a negative number cannot have a square root or be a perfect square, it can be a square root.
8 is the only positive square root, but every number that has a square root, also has a second one, the negative version.
-8 is also the square root because it can be multiplied by itself to get 64 :D
The real square roots of the integer 64 will have 8 and -8.
What is a number system?The number system is a way to represent or express numbers.
A decimal number is a very common number that we use frequently.
Any of the multiple sets of symbols and the guidelines for utilizing them to represent numbers are included in the Number System.
Let's say the square root of 64 is x.
x = √64
Square both sides
x² = (√64)² = 64
x² = 64
Now, find two equal number that gives 64 by multiplying.
Consider, 8 and 8 → 8² = 64
Thus, x = 8
Another could be -8 and -8 → (-8)² = 64
Hence "The real square roots of the integer 64 will have 8 and -8".

Therefore, the first, second, and last options are correct.
Question :
Equation of the axes: The equation of the axes of a hyperbola is x = h, where h is the x-coordinate of the center of the hyperbola.
Equation of the asymptotes: The equation of the asymptotes of a hyperbola is y = ±(b/a)x, where a and b are the distances from the center to the vertices along the transverse and conjugate axes.
Equation of the conjugate hyperbola: The equation of the conjugate hyperbola can be found by interchanging a and b in the equation of the original hyperbola.
Review each statement to determine if it is true for a hyperbola
1. "A point on a hyperbola that sits on the transverse axis is called a vertex." - True. That's because the vertices of a hyperbola are indeed points on the hyperbola that line up with the transverse axis.
2. "The center of a hyperbola is right in the middle of its vertices." - True. Think of it like finding the midpoint between two ends. That's where the center of the hyperbola sits.
3. "A hyperbola's vertex is exactly where it meets the transverse axis." - false.
4. "The transverse axis of a hyperbola is the line connecting its vertices and foci." - False. The transverse axis actually links the vertices directly, not the vertices and the foci.
5. "The directrices of a hyperbola are two lines that run parallel to its conjugate axis, and they're positioned at a distance from the center to match the distance from the center to the foci." - True. It's like setting up boundaries at a certain distance from the center to guide the shape of the hyperbola.

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%.
On a recent trip to the convenience store, you picked up 4 gallons of milk, 6 bottles of water and 5 snack size bags of chips. You total bill before tax was $ 29.7. If a bottle of water costs twice as much as a bag of chips, and a gallon of milk costs $1.80 more than a bottle of water, how much does each item cost
Answer:
Milk $3.60
Water $1.80
Chips $0.90.
Step-by-step explanation:
If w = cost of 1 bottle of water, m = cost of 1 gal of milk and c cost of 1 bag of chips we have.
4m + 6w + 5c = 29.7
Also we have w = 2c and m = 1.8 + w.
From the first equation we have c = w/2.
So substituting for c and m in the initial equation we have:
4(1.8 + w) + 6w + 5(w/2) = 29.7
7.2 + 4w + 6w + 2.5w = 29.7
12.5w = 22.5
w = 1. 80.
So c = w/2 = 1.8/2 = 0.90.
and m = 1.8 + 1.8 = 3.60.
The cost of bag of chips is $5.58 , bottle of water is $ 11.16 and gallon of milk is $12.96.
What is an Equation ?An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.
It is given that
4 gallons of milk, 6 bottles of water and 5 snack size bags of chips costs $29.7
Let the price of bag of chips is $x
Then
bottle of water , y costs twice as much as a bag of chips
y = 2x
a gallon of milk , z costs $1.80 more than a bottle of water
z = y +1.8
z = 2x +1.8
The equation that will be formed is
x + 2x + 2x +1.8 = 29.7
5x +1.8 = 29.7
5x = 27.9
x = $5.58
y = $11.16
z = $12.96
Therefore the cost of bag of chips is $5.58 , bottle of water is $ 11.16 and gallon of milk is $12.96.

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

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.

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

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]

Each time x goes up by 2, y decreases by 4
This indicates we have a linear function. The slope in this case would be
m = rise/run = (change in y)/(change in x) = -4/2 = -2
The y intercept can be found by following these steps
y = mx+b
0 = -2(5)+b
0 = -10+b
10 = b
b = 10
Therefore, the equation of this line is y = -2x+10. Plug in something like x = 1 and it should lead to y = 8. The same applies for any other column of x,y values.
