The volume of the cylinder is 64/3773 cubic units

The formula for calculating the volume of a cylinder is expressed as:

V = πr²h

where

r is the radius

h is the height

Given the following parameters

r = 2/7units

h =8/11 units

Substitute

V = 22/7 * 2/7 * 2/7* 8/11
V = (2/7)³ * 8/11
V = 8/343 * 8/11
V = 64/3773 cubic units

Hence the volume of the cylinder is 4/3773 cubic units

The surface area of the composite figure is 714 sq. in.

Let, a be the edge of the cube.

Then, surface area of the cube = 6a² square unit

Let, length of the cuboid = l unit

Width of the cuboid = w unit

Height of the cuboid = h unit

Then, surface area of the cuboid = 2(lw+lh+hw) square unit

Given, edge of cube = 4 in.

∴ Surface area of cube = (6×4²) sq. in. = 96 sq. in.

Now, given, length of cuboid = 15 in.

Width of the cuboid = 10 in. & height of the cuboid = 7 in.

∴ Surface area of the cuboid = 2{(15×10)+(15×7)+(10×7)} sq. in.

                                                = 2{150+105+70} sq. in.

                                                = 2{325} sq. in. = 650 sq. in.

Here, we have to find the surface area of the composite figure.

We have to subtract the surface area from both of cube & cuboid, where they are attached.In that case, we have to subtract (4×4) from both.

So, we have to subtract 2(4×4) sq. in. = 32 sq. in.

∴ The surface area of the composite figure = (650+96-32) sq. in.

                                                                        = 714 sq. in.

An x-intercept is the point where the line of a graph passes through the x-axis. Thus, you should look for this point on the given graph.

A graph can be defined as a type of chart that is used for the graphical representation of data on both the horizontal and vertical lines of a Cartesian coordinate i.e x-axis and y-axis.

In Mathematics, x-intercept refers to the point where the line of a graph passes through the x-axis as shown in the image attached below. Since the graph wasn't provided for this question, you should look for the point where the line passes or crosses through the x-axis.

Step-by-step explanation:

The general equation for slope-intercept form is:

y = mx + b

In this form, "m" represents the slope and "b" represents the y-intercept. Since you have been given both of these values, you can plug them into the formula to find your answer.

slope (m) = 5/3

y-intercept (b) = 4

y = mx + b

y = (5/3)x + 4

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Jose bought 750 bags of peanuts for $375.00.

He intends to sell each bag for $0.15 more than he paid.

Then the amount of charge for one bag of peanuts will be

Angle sum property of triangle: Sum of all the angles of a triangle is 180

Alternate interior angles: When two parallel lines are intersected by a transversal, the pair of angles on the inner side of  each of these lines but on the opposite side of the transversal are called  alternate interior angles

In ΔABC,

  ∠1 + 90 + 38 = 180    {angle sum property of triangle}

         ∠1 + 128 =  180

               ∠1     = 180 - 128

When the coefficient of x is positive, the graph of a line rises and moves to the right. Option C is correct.

A diagram depicting the relationship between two or more variables, each measured along with one of a pair of axes at right angles.

The complete question is

"The graph of a line goes up and to the right when:

a) the coefficient of x is 0

b) the coefficient of x is negative

c) the coefficient of x is positive

d) there is no coefficient of x"

When the coefficient of x is positive, we know that the graph of a line will move upward and to the right.

Since we are aware that a line's upward and rightward movement indicates that the line is advancing, we will obtain a positive slope for the line, and we are also aware that the slope-intercept of a line is provided as:

y= mx+c

If m is a positive number, then positive is the coefficient of x.

The graph of a line goes up and to the right when the coefficient of x is positive.

Hence option C is correct.

The value of f(x) = 3x² - 2x at x = 4 is 40.

The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math.

Here, the given function;

    f(x) = 3x² - 2x

put the value of x = 4, we get

     f(4) = 3 X 4² - 2 X 4

     f(4) = 3 X 16 - 8

      f(4) = 48 - 8

     f(4) = 40

Thus, the value of f(x) = 3x² - 2x at x = 4 is 40.

Answer:

if you're supposed to be solving for x then the top one is x=-y+3 and the bottom is x=-y+5

Answer:

I think the answer is 5 ( if wrong then do a low rating)

Step-by-step explanation:

The way I found the answer was by using PEDMAS so first I handled [(4 - (-5)) x (-7)] which is the same as 4 + -5 which equals -1 and when multiplied by -7 equals positive 7 because whenever you multiply 2 negatives you get a positive.

Next I solved 6 / (-3) which is -2 since whenever a positive is divided by a negative the quotient is negative. Now the equation is:

-2 + 7 and when solved is -2 + 7 = 5

Answer:

B

Step-by-step explanation:

-2|x - 1| = -4

|x - 1| = 2

since we are dealing with a function that brings 2 values to the same result, the reverse function (needed to find the values of x that create the result y) has 2 branches :

(x - 1) = 2

and

(x - 1) = -2

x - 1 = 2

x = 3

x - 1 = -2

x = -1

therefore, B is the right answer.

Using an exponential function, it is found that the half-life of the substance is of 5.23 units of time.

The function is given by:

[tex]A(t) = A(0)e^{-kt}[/tex]

In which:

The parameters are given by:

A(0) = 48,  k = 0.1325.

Hence the equation is:

[tex]A(t) = 48e^{-0.1325t}[/tex]

The half-life is the amount of time for which A(t) = 0.5A(0) = 24, hence:

[tex]A(t) = 48e^{-0.1325t}[/tex]

[tex]24 = 48e^{-0.1325t}[/tex]

[tex]e^{-0.1325t} = 0.5[/tex]

[tex]\ln{e^{-0.1325t}} = \ln{0.5}[/tex]

[tex]0.1325t = -\ln{0.5}[/tex]

[tex]t = -\frac{\ln{0.5}}{0.1325}[/tex]

t = 5.23.

Using the continuity concept, as the value of the function has to be equal to the limit, it is found that the value of k is of k = -4.

A function is said to be continuous at x = a if, and only if:

[tex]\lim_{x \rightarrow a} f(x) = f(a)[/tex]

In this problem, we have to check at x = -2, hence:

[tex]\lim_{x \rightarrow -2} f(x) = f(-2)[/tex]

[tex]k = \lim_{x \rightarrow -2} f(x)[/tex]

For the limit, we have to check the lateral conditions, hence:

[tex]\lim_{x \rightarrow -2} f(x) = \lim_{x \rightarrow -2} \frac{x^2 - 4}{x + 2} = \lim_{x \rightarrow -2} \frac{(x - 2)(x + 2)}{x + 2} = \lim_{x \rightarrow -2} x - 2 = -2 -2 = -4[/tex]

Hence, from the continuity condition, k = -4.
