Find the surface area of a square pyramid with side length 2 yd and slant height 2 yd.
The surface area of the square Pyramid with a side length of 2 yards and a slant height of 2 yards is 12 square yards.
The surface area of a square pyramid, we need to calculate the area of each face and then sum them up.
A square pyramid has four triangular faces and one square base. The area of the base is equal to the side length squared, while the area of each triangular face can be found using the formula: (1/2) * base * height.
Given that the side length of the square pyramid is 2 yards and the slant height is also 2 yards, we can calculate the surface area as follows:
Area of the base = (side length)^2 = 2^2 = 4 square yards
Area of each triangular face = (1/2) * base * height = (1/2) * 2 * 2 = 2 square yards
Now, let's calculate the total surface area of the square pyramid:
Total surface area = Area of the base + 4 * Area of each triangular face
Total surface area = 4 + 4 * 2 = 4 + 8 = 12 square yards
Therefore, the surface area of the square pyramid with a side length of 2 yards and a slant height of 2 yards is 12 square yards.

The measures of the angle of a triangle are shown on the figure below. Solve for X.
Internal angles sum: 180(sides-2) = 180
5x = 180 - (48 + 90 + 17)
x = 25/5
x = 5
answer: 5
proof:
(90 + 48) + (5(5)+17) = 180
Answer:
x=5
Step-by-step explanation:
We know that a triangle consists of 180°. So to start, you take the two given angles and add them together. 48+90=138.
Now you subtract the 138 from the total of 180 to get the degrees of the remaining angle. 180-138=42°.
Now set the unknown angle equal to 42. (5x+17) = 42
Subtract 17from both sides to get 5x=25
Divide 5 from both sides to get x=5

The concept of best-, worst-, and average-case analyses extends beyond algorithms to other counting problems in mathematics. Recall that the height of a binary tree is the number of edges in the longest path from the root to a leaf. Find the best-case height of a binary tree with seven nodes.
the height of a binary tree is the number of edges in the longest path from the root to a leaf.The best-case height of a binary tree with seven nodes is 3.
A binary tree is a type of tree structure consisting of nodes that are connected by edges. The number of edges in the longest path from a binary tree's root to a leaf determines the tree's height.In the best-case scenario, the binary tree is perfectly balanced and each node has exactly two children. With seven nodes, the best-case height is three because each node has two children and three edges connect the root node to the leaves. This means that the longest path from the root to a leaf is three edges, resulting in a height of three.

A car advertisement states that a certain car can accelerate from rest to 72 km/h in 12.5 seconds.
Initially the car is at rest, so the initial velocity is ______
m/s.
The car speeds up to 72 km/h which is equivalent to _______
m/s. Find the car’s average acceleration.
The acceleration of the car is _______
m/s2
The initial velocity is 0 m/sec
The car speed up to 72km/h which is equivalent to 36m/sec
The acceleration of the car is 2.88 m/sec².
What is acceleration?Acceleration is the rate of change of the velocity of an object with respect to time. Vector quantities are accelerations. Acceleration = (Final Velocity - Initial Velocity)/ Time taken
Given that car can accelerate from rest to 72km/h in 12.5 seconds. Therefore, we can write:
Initial Velocity = 0 m/sec
Final Velocity = 72 km/hr = 72×(0.50) m/sec = 36m/sec
Time taken = 12.5 second
Now, the car’s acceleration in m/s can be written as,
Acceleration = (Final Velocity - Initial Velocity)/ Time taken
(36 m/sec - 0 m/sec)/12.5 seconds
= 2.88 m/sec²
Hence, the car’s acceleration in m/s is 2.88 m/sec².

which table represents a linear function?
Answer:
Bottom right table
Step-by-step explanation:
A table will show a linear relationship when there is a common difference. To determine this, we first ensure that the x values are increasing at the same value and then find the difference of consecutive y values.
Top left table
11-7=3
12-11=1
13-12=1
Because the differences between the y values are not all the same, this table does not represent a linear function.
Top right table
9-7=2
12-9=3
15-12=3
Again, there is no common difference, so this table does not represent a linear function.
Bottom left table
The x values are different now but they still increase by the same increment each time, so we continue subtracting the y values normally.
9-7=2
12-9=3
15-12=3
This table does not represent a linear function.
Bottom right table
9-7=2
11-9=2
13-11=2
Because there is a common difference, this table represents a linear function.

The maintenance department at the main campus of a large state university receives daily requests to replace fluorecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 59 and a standard deviation of 3. Using the 68-95-99.7 rule, what is the approximate percentage of lightbulb replacement requests numbering between 59 and 62
Answer:
About 34%
Step-by-step explanation:
Given that :
Mean, m = 59 ; Standard deviation, s = 3
Bulb replacement numbering between 59 and 62
For, x = 59
Zscore = (x - m) / s
Z = (59 - 59) / 3 = 0
For x = 62
Z = (62 - 59) / 3 = 1
P(Z < 1) - P(Z < 0)

The function
f(x) = 5sqrt(x + 13) + 5 has an inverse f ^ - 1 * (x) defined on the domain x < 5 Find the inverse. x >= - 13
The inverse function: \(f^{-1} (x) =\) \((\frac{x -5}{5} )^{2} -13\)
The inverse is defined on the domain x < 5 and x ≥ -13 for the original function, which means that the range of the original function is y ≥ 5.
What is a function?A function is a relationship that exists between two sets of numbers, with each input from the first set, known as the domain, corresponding to only one output from the second set, known as the range.
Given function is; \(f(x) = 5\sqrt{(x + 13)} + 5\)
To find the inverse of the given function, we first replace f(x) with y:
⇒ \(y = 5\sqrt{(x + 13)} + 5\)
Subtract 5 from both sides:
⇒ \(y -5 = 5\sqrt{(x + 13)}\)
⇒ \(\frac{(y -5)}{5} = \sqrt{(x + 13)}\)
⇒ \((\frac{y -5}{5} )^{2} = x + 13\)
⇒ \((\frac{y -5}{5} )^{2} -13 = x\)
Now we have x in terms of y, so we can replace x with f⁻¹(x) and y with x to get the inverse function:
f⁻¹(x) = \((\frac{x -5}{5} )^{2} -13\)
The domain of the inverse function is x ≥ 5, because this is the range of the original function, and we were given that the inverse is defined on the domain x < 5. However, we must also exclude the value x = 5, because the denominator of the fraction \((\frac{x -5}{5} )^{2}\) becomes zero at this value. Therefore, the domain of f⁻¹(x) is x > 5.
We were given that x ≥ -13 for the original function, which means that the range of the original function is y ≥ 5. Therefore, the domain of the inverse function becomes the range of the original function, and the range of the inverse function becomes the domain of the original function.

According to the concept of algebraic expression and arithmetic, the correct answers are A) Number of adults = N - 25. B) Number of adults when N = 124: 124 - 25 = 99
A) Let's denote the number of children as N. Since there are 25 fewer adults than children, the number of adults can be expressed as N - 25.
B) If there are 124 children, we substitute N with 124 in the expression from part A. Thus, the number of adults would be 124 - 25 = 99.
To arrive at these answers, we used the given information that there are "N" children and 25 fewer adults than children. By substituting the value of N, we determined the number of adults in terms of N and then calculated the specific number of adults when N is equal to 124.

y = (3/4)x-9/2
Step-by-step explanation:
We've got two points, (-2, -6) and (2, -3). That's more than enough info to construct a line. The slope of the line is the ratio between the change in y (Δy) and the change in x (Δx). Here, Δy = -3 - (-6) = -3 +6 = 3, and Δx = 2 - (-2) = 2 + 2 = 4, so the slope is Δy/Δx = 3/4. From here, we can use the point-slope form of a line to get a general equation. With the slope m = 3/4 and choosing the point (2, -3), we have

Answer:
x = 10
Step-by-step explanation:
There are 6 numbers in total: 2, 3, 4, 5, 6, and whatever x is. In order for the average to be 5 in this scenario, all numbers must add up to 30, because 30/6 = 5.
2 + 3 + 4 + 5 + 6 = 20. 30-20=10. This means x would need to equal 10.
