Parent function:  The most basic function in a family of functions is the parent function. A family of functions is a collection of functions that have similar graph shapes because they all have the same greatest degree.

Four graphs that illustrate the U-shaped graph, or parabola, are displayed in the graph above. We can classify them as belonging to the same family of functions since they all have the same highest degree of two and the same form.

Exponential parent function: Algebraic expressions appear in the exponent of exponential functions. The formula for its parent function is y = [tex]b^{x}[/tex], where b can be any non-zero constant.

For above definitions we can conclude that all options given to us are exponential parent function.

The required slope-intercept form of the equation of the line is y = x/4 + 3.

To determine the equation of the line in slope-intercept form passing through the points (4, 4) and (0, 3).

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

here,

m = (y₂ - y₁) /  (x₂ - x₁)

Substitute the points,
m = [3 - 4] / [0 - 4]
m = 1 / 4

The Method of Cylindrical Shells will be used to assist.

As previously, we construct a region R that is enclosed on the top by the graph of the function y = f (x), on the bottom by the x axis, and on the left and right by the lines x = a and x = b, respectively (a).

As seen in Figure 1, we then rotate this region around the y-axis (b). Be aware that this is distinct from what we have previously done..

Previously, areas that were described in terms of x-functions were centered on the x-axis or a line that ran parallel to it.

Since the shell is a cylinder, its volume equals the cross-sectional area times the cylinder's height. The cross-sections are annuli, which are essentially circles with holes in the middle and are formed like rings.

According to our question-

V= 2π ∫025/2 x [ 5 - √(2x) ] d x = 625π/ 4 cubic units

The average speed of the trains are Bullet train = 91.4 km/hr and Ordinary train = 24.9 km/hr

From the question, we have the following parameters that can be used in our computation:

Bullet train

Distance = 320 km

Time = 3 and half hours = 3.5

Ordinary train

Distance = 212 km

Time = 8 and half hours = 8.5

By definition, the speed of an object is the ratio of the distance moved by the object and the time travelled by the object

Mathematically, this can be represented as

Speed = Distance : Time

Express as fraction

Speed = Distance/Time

So, we have

Bullet train = 320/3.5 = 91.4

Ordinary train = 212/8.5 = 24.9

Hence, the speed of the ordinary train is 24.9 km per hour

The circumference of the given circle with the diameter 27.6 yards is 86.7 yards.

The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its center. A meridian is any great circle passing through a point designated a pole.

Given that, the diameter of circle is 27.6 yards

Radius of a circle is the distance from the center of the circle to any point on it's circumference and radius of a circle is half of Diameter.

That is, radius =Diameter/2

So, radius of circle =27.6/2 =13.8 yards

We know that, the circumference of the circle is 2πr

Now, circumference = 2×3.14×13.8

= 86.664

≈ 86.7 yards

???

(x + y) + 3

this is 3 more than the sum of x and y.

In image.

In the Image is the anser and explanation.

Answer:

The correct answer is (1, -3).

Step-by-step explanation:

To solve this question, we should use substitution. This means we can substitute the value given for y (as indicated by the second equation) into the first equation. This is shown below:

4x + y = 1

4x + (x - 4) = 1

We simplify the left side of the equation and then solve for x.

5x - 4 = 1

5x = 5

x = 1

We must also solve for y. To do this, we can plug in x = 1 into either of the given equations.

y = x - 4

y = 1 - 4

y = -3

Therefore, x = 1 and y = -3. The question asks us to express the answer as an ordered pair (x,y), so the answer is (1, -3).

We can determine whether the rocket is ascending or descending by evaluating the derivative at that time. If the derivative is positive, the rocket is ascending. If the derivative is negative, the rocket is descending.

What is a derivative of a function?

The derivative of a function can be interpreted as the slope of the graph of the function or, more precisely, as the slope of the tangent line at a point. Its calculation, in fact, derives from the slope formula for a straight line, except that a limiting process must be used for curves.

To determine whether the rocket is ascending or descending at a given time, we need to find the derivative of the function h(t) and determine whether it is positive or negative.

The derivative of h(t) is given by h'(t) = -t²+42t+43. This is the rate of change of the height of the rocket at any given time. If the derivative is positive, the rocket is ascending. If the derivative is negative, the rocket is descending.

At t = 1 second, h'(t) = -1 + 42 + 43 = 44. Since the derivative is positive at t = 1, we know that the rocket is ascending at this time.

Hence, we can determine whether the rocket is ascending or descending by evaluating the derivative at that time. If the derivative is positive, the rocket is ascending. If the derivative is negative, the rocket is descending.

If one of the angles in a triangle is 90 degrees, the triangle is said to have a right angle. The term "right angle" refers to angles in right triangles that are 90 degrees. The side opposite in a 90° angle is the hypotenuse. The hypotenuse is always the longest side. The sum of the other two inner angles is 90 degrees.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry.

The shape of the sampling distribution of the mean for samples of size 45 will be normal.

This is because the sampling distribution of the mean approaches normality as the sample size increases. The center of the sampling distribution will be 67 inches, which is the mean height of the population. The spread of the sampling distribution will be determined by the standard deviation of the population and the sample size. Specifically, the standard deviation of the sampling distribution will be equal to the standard deviation of the population divided by the square root of the sample size. In this case, the standard deviation of the sampling distribution will be 3.8 inches / sqrt(45) = 0.55 inches.
