Step-by-step explanation:

Let us suppose that the function is, \(\[y = \int\limits_{3}^{\tan x} {\sqrt {2t} + \sqrt t } \,dt\]\)We need to find the derivative of the above function. We will be using part 1 of the fundamental theorem of calculus for finding the derivative. the derivative of the function is\(\[y'(x) = \sec ^2 x\left( {\sqrt {2\tan x} + \sqrt {\tan x} } \right)\].\)

Using the fundamental theorem of calculus part 1, we have,\(\[y'(x) = \frac{d}{{dx}}\int\limits_{3}^{\tan x} {\sqrt {2t} + \sqrt t } \,dt\]\) Let us find the derivative of \[y'(x)\] by applying the Leibniz rule.

Hence,\(\[y'(x) = \frac{d}{{dx}}\left( {\int\limits_{3}^{\tan x} {\sqrt {2t} + \sqrt t } \,dt} \right)\]$$y'(x) = \left( {\frac{d}{{d(\tan x)}}\int\limits_{3}^{\tan x} {\sqrt {2t} + \sqrt t } \,dt} \right)\left( {\frac{d(\tan x)}{{dx}}} \right)$$$$\\)

Rightarrow \(y'(x) = \left( {\sqrt {2\tan x} + \sqrt {\tan x} } \right)\left( {\sec ^2 x} \right)$$$$\\)

Rightarrow\(y'(x) = \sec ^2 x\left( {\sqrt {2\tan x} + \sqrt {\tan x} } \right)\]\)

To determine the probability that a randomly selected guest is accepted by the host, we need more information about the scenario. For instance, we should know the total number of guests and the number of accepted guests. Let's say there are 'n' guests, and 'a' guests are accepted by the host.
Step 1: Identify the terms.
- n: Total number of guests
- a: Number of accepted guests
Step 2: Calculate the probability.
To find the probability, we'll divide the number of accepted guests (a) by the total number of guests (n). So, the probability is:
P(Accepted) = a / n
Step 3: Identify the type of probability.
In this case, the probability we've calculated is the "marginal probability," as it represents the likelihood of a single event occurring (a guest being accepted) without considering any other factors or events.

The required equation in terms of x that represents the given relationship is x² - 8x - 240 = 0.

Given that the height of a triangle is 8ft less than the base x. Also, the area is 120ft². We need to find the equation in terms of x that represents the given relationship of the triangle. Let's solve it.

Step 1: We know that the formula to calculate the area of a triangle is, A = 1/2 × b × h, Where A is the area, b is the base, and h is the height of the triangle.

Step 2: The height of a triangle is 8ft less than the base x. So, the height of the triangle is x - 8 ft.

Step 3: The area of the triangle is given as 120 ft².So, we can write the equation as, A = 1/2 × b × hx - 8 = Height of the triangle, Base of the triangle = x, Area of the triangle = 120ft². Now substitute the given values in the formula to get an equation in terms of x.120 = 1/2 × x × (x - 8)2 × 120 = x × (x - 8)240 = x² - 8xSo, the equation in terms of x that represents the given relationship isx² - 8x - 240 = 0.

In this movie, the ratio of children to adults suggests that there are 27 children in attendance.

We have to give that,

There are 9 children for every 4 adults.

This means that if there were 13 people, 9 of them would be children and 4 would be adults.

Children would therefore be:

= 9 / 13

If there were 39 people, the number of children would be:

= 9/13 x 39

= 27 children

\($= \frac{21}{4}-\left(\frac{13}{5}+\frac{25}{6} \times \frac{8}{25} \right)$\)

Answer:

\(m = - \frac{1}{4} \)

\(c = 2 \frac{3}{4} \)

Step-by-step explanation:

Let's start by finding the point of intersection of the lines x -2y= -1 and y= 2.

x -2y= -1 -----(1)

y= 2 -----(2)

Substitute (2) into (1):

x -2(2)= -1

x -4= -1

x= 4 -1

x= 3

Thus, the point of intersection is (3, 2).

y= 4x +8

Slope= 4

The product of the slopes of perpendicular lines is -1.

4m= -1

m= -¼

y= -¼x +c

Since the line passes through (3, 2), we can substitute this coordinates into the equation to find the value of c.

When x= 3, y= 2,

\(2 = - \frac{1}{4} (3) + c\)

\(c = 2 + \frac{3}{4} \)

\(c = 2 \frac{3}{4} \)

Answer in the picture.

The function can be expressed as a piecewise function as,

f(x) = -1, x < 3 and x > 3

f(x) = -4, x = 3

A piecewise function is a function which has different definitions of values for different intervals.

Given is a graph of a function.

A line is drawn through y = -1 for all the points of x, except at the point x = 3.

At x = 3, the value of y = -4

So we can define the function as,

f(x) = -1 for all x other than 3 and f(x) = -4 for x = 3.

Or in other words,

f(x) = -1, for x < 3 and x > 3

f(x) = -4 for x = 3

Hence the piecewise function defined is f(x) = -1, for x < 3 and x > 3

f(x) = -4 for x = 3.

In response to the query, Line C traverses Point (10, 10) & (1, 5). Line d and line c are parallel, and line d's slope is 5/9.

Parallel in mathematics refers to the different vectors that should never have cross each other with. Parallel relates directly to complementarity or contemporaneous higher incidence.

A straight line's general equation is: y = mx + c [m] where [m] is the slope of the line and represents the unit change rate of [y] without respect to [x].

The y-intercept, or the place where the graph crosses the [y] axis, is represented by [c].

When (x1, y1) and (x2, y2) are really the coordinates of 2 points on the line, m = (y2 - y1) / (x2 - x1).

adding the values we obtain,

m = (5 - 10) / (1 - 10) = -5 / -9 = 5/9

Therefore, the slope of line [d] would be 5/9.

Answer:

x = 7.2 , y = 57 , z = 10.8

Step-by-step explanation:

the sum of the 3 angles in the outer triangle = 180° , that is

y + 88 + 35 = 180

y + 123 = 180 ( subtract 123 from both sides )

y = 57

------------

the outer and inner triangles are similar ( AA postulate ) then the ratios of corresponding sides are in proportion, that is

\(\frac{x}{12}\) = \(\frac{9}{9+6}\) = \(\frac{9}{15}\) ( cross- multiply )

15x = 108 ( divide both sides by 15 )

x = 7.2

and

\(\frac{z}{18}\) = \(\frac{9}{15}\) ( cross- multiply )

15z = 162 ( divide both sides by 15 )

z = 10.8
