The expression f(x 2), we substitute x 2 into the function f(x). Therefore, f(x 2) = 8x^2 + 5 and f(2) = 13.
To evaluate the expression f(x 2), we substitute x 2 into the function f(x). Thus, f(x 2) = 2(x 2)^2 + 5.
To simplify this expression, we first simplify the exponent by applying the power rule.
We have (x 2)^2 = (x^2)(2^2) = (x^2)(4) = 4x^2. Substituting this back into the expression, we get f(x 2) = 2(4x^2) + 5.
Simplifying further, we have f(x 2) = 8x^2 + 5. To find f(2), we substitute x = 2 into the function f(x).
Thus, f(2) = 2(2)^2 + 5. Simplifying, we have f(2) = 2(4) + 5 = 8 + 5 = 13.
Therefore, f(x 2) = 8x^2 + 5 and f(2) = 13.

Answer:
The lateral area of cone is 260π in².
Step-by-step explanation:
Given : \(\small\blue\bull\) Height of cone = 24 in.\(\small\blue\bull\) Radius of cone = 10 in.\(\begin{gathered}\end{gathered}\)
To Find : \(\small\blue\bull\) Slant height of cone \(\small\blue\bull\) Lateral surface area of cone\(\begin{gathered}\end{gathered}\)
Using Formulas :\(\star{\underline{\boxed{\sf{\purple{\ell = \sqrt{{(r)}^{2} + {(h)}^{2}}}}}}}\)
\(\pink\star\) l = slant height \(\pink\star\) r = radius \(\pink\star\) h = height\(\star{\underline{\boxed{\sf{\purple{La_{(Cone)}= \pi r\ell}}}}}\)

Classified ads in a newspaper offered for sale 20 used cars of the same make and model. The output of a regression analysis is given. Assume all conditions for regression have been satisfied. Create a 95% confidence interval for the slope of the regression line and explain what your interval means in context. Find the 95% confldence interval for the slope. The confidence interval is (Round to two decimal places as needed.)
Confidence interval refers to a statistical measure that helps quantify the amount of uncertainty present in a sample's estimate of a population parameter.
This measure expresses the degree of confidence in the estimated interval that can be calculated from a given set of data. In this scenario, the task is to build a 95% confidence interval for the regression line's slope. The regression analysis output has already been given. According to the output given, the estimated regression model is:y = 25,000 + 9,000 x, where x represents the number of miles the car has been driven and y represents the car's selling price.
The formula to calculate the 95% confidence interval for the slope is:Slope ± t · SE, where Slope is the point estimate for the slope, t represents the critical t-value for a given level of confidence and degrees of freedom, and SE represents the standard error of the estimate. The value of t can be calculated using the degrees of freedom and a t-table. Here, the number of pairs in the sample size is 20, and the model uses two parameters.
Therefore, the degrees of freedom would be 20 - 2 = 18.The critical t-value for a 95% confidence interval and 18 degrees of freedom is 2.101. Using the formula given above, we can calculate the 95% confidence interval for the slope as follows:Slope ± t · SE= 9000 ± (2.101)(700) ≈ 9000 ± 1,467.7 = [7,532.3, 10,467.7]Therefore, the 95% confidence interval for the slope is [7,532.3, 10,467.7]. This means that we are 95% confident that the true value of the slope for this model falls within the interval [7,532.3, 10,467.7].
It implies that the price of the car increases by $7,532.3 to $10,467.7 for each mile driven by the car. In conclusion, a 95% confidence interval has been calculated for the regression line's slope, which indicates that the actual slope of the model lies between the range [7,532.3, 10,467.7].

A veterinarian measures the weight of each puppy in a litter. She records the puppies' weights in pounds. Puppy Weights: 2. 9, 3. 0, 3. 1, 3. 1, 3. 2, 3. 3, 3. 3, 3. 4, 4. 4 The veterinarian removes the outlier of the data. By how many pounds, rounded to the nearest hundredth of a pound, will the mean of the data change with the removal of the outlier?
The mean of the puppy weights changes by 0.14 pounds.
To determine how the mean of the puppy weights changes with the removal of the outlier, follow these steps:
1. First, identify the outlier in the given data set: Puppy Weights: 2.9, 3.0, 3.1, 3.1, 3.2, 3.3, 3.3, 3.4, 4.4. The outlier is 4.4 as it is significantly higher than the rest of the values.
2. Calculate the mean with the outlier: Add all the weights and divide by the total number of puppies (9). (2.9+3.0+3.1+3.1+3.2+3.3+3.3+3.4+4.4)/9 = 29.7/9 = 3.3
3. Calculate the mean without the outlier: Remove the outlier (4.4) from the sum and divide by the new total number of puppies (8). (29.7 - 4.4)/8 = 25.3/8 = 3.1625
4. Calculate the change in mean by subtracting the mean without the outlier from the mean with the outlier, and round to the nearest hundredth of a pound: 3.3 - 3.1625 = 0.1375, which rounds to 0.14.
With the removal of the outlier, the mean of the puppy weights changes by 0.14 pounds.

Two buses, which are 2400 miles apart, travel towards each other. Their speeds differ by 60 miles per hour. They pass each other after 5 hours. Find their speeds.
According to the Question
Two buses started 2400 miles apart
They pass each other and they must have together to cover = 2400 miles
Now
Using Formula :-
Distance = Speed × Time
First bus ⇒ 5 × b = 5b
Second bus ⇒ 5(b + 60)
Now put in a Equation we get :-
5b + 5(b + 60) = 2400
5b + 5b + 300 = 2400
10b + 300 = 2400
10b = 2400 - 300
10b = 2100
b = 2100 / 10
b = 210
Hence :-
One bus speed is 210 miles
Another bus speed ⇒ 210 + 60 = 270 miles

As a result, the right triangle's hypotenuse measures about 43.3 units in length.
How is hypotenuse determined?The Pythagorean theorem, which asserts that the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides, can be used to determine the length of the hypotenuse of a right triangle.
In this instance, we are aware of the right triangle's one angle's value of 55 degrees and the base's length of 27 units. The sine function, which links the ratio of the height to the hypotenuse to the sine of the angle, can be used in trigonometry to get the length of the other side (the height):
height/hypotenuse equals sin(55)
We can find the hypotenuse by rearranging this equation:
Height / sin is the hypotenuse (55)
When we enter this height expression into the first equation, we obtain:
(Base) / cos = hypotenuse (55)
By entering the specified values, we obtain:
Hypotenuse = 27/Cos(55), which is 43.3
