What is the value of p ?

Answer:

log_2((x^4+4x^3)/3)

Step-by-step explanation:

First step would be distribute that - into the ( )

3log_2(x)-log_2(3)+log_2(x+4)

Now take care of coefficients of the logs... bring them up as powers of the inside

log_2(x^3)-log_2(3)+log_2(x+4)

or

+log_2(x^3)-log_2(3)+log_2(x+4)

Now for the product and quotient rule! If it has a + in front of it, it will go on top. If it has a - in front of it, it will go on bottom.

Like this:

log_2 (x^3(x+4)/3)

or

log_2((x^4+4x^3)/3)

So inside that log base 2 thing the top is x^4+4x^3

and that bottom is 3

36 donuts (2 1/2 dozen) = $8.00

So, you divide 8 by 36 and you get about 22¢ for each donut. Then, you do .22 x 12 which equals $2.64.

One dozen donuts = $2.64

The cost of the one dozen donuts will be $2.64.In one dozen their is 12 donuts.

Arithmetic is an area of mathematics involving the study of numbers and the different operations that can be performed on them.

[tex]\rm 1 \ dozen = 12 \ donuts \\\\ 2\frac{1}{2} dozen = 2\frac{1}{2} \times 12\\ \\\\ 2\frac{1}{2} dozen = 36 \ donuts[/tex]

36 donuts=  $8.00

1 donuts =  $ 0.22

1 dozen donuts cost  = 12 × $ 0.22

1 dozen donuts cost  = $ 2.64

Hence,the cost of the one dozen donuts will be $2.64.

Step-by-step explanation:

Here,

radius of hemisphere and cylinder(r)=7 cm

height of the cylinder(h)= 10 cm

Now the volume of cylinder(V1) is,

[tex]\pi {r}^{2} h \\ = \pi \times {7}^{2} \times 10 \\ = 1540 \: {cm}^{3} \\ [/tex]

And the volume of hemisphere(V2) is,

[tex] \frac{2}{3} \pi {r}^{3} = \frac{2}{3} \times \pi \times {7}^{3} \\ = 718.67 \: {cm}^{3} [/tex]

Total volume=V1+V2=1540+718.67= 2258.67 cu.cm

Surface area of cylinder(A2)=

[tex]2\pi \: rh + 2\pi {r}^{2} = 2\pi \: r(h + r) \\ = 2 \times \pi \times 7 \times (10 + 7) \\ = 44 \times 17 \\ = 748 \: {cm}^{2} [/tex]

Surface area of hemisphere(A2)=

[tex]2\pi {r}^{2} = 2 \times \pi \times {7}^{2} = 308 \: {cm}^{2} [/tex]

Then total Surface area=A1+A2

=748+308=1056 sq.cm

1. First, let us find the volume. Now the total volume is simply given by adding the volume of the cylinder to that of the hemisphere.

Let us revisit the formulas for the volume of a cylinder and hemisphere.

Cylinder: V = πr^(2)h

Hemisphere: V = (2/3)πr^3

Thus, the total volume is given by πr^(2)h + (2/3)πr^3

Using the values provided in the diagram, we can now say that:

Total volume = π(7)^(2)*10 + (2/3)π(7)^3

= 490π + 686π/3

= 2156π/3 cm cubed

Using π = 22/7, we can now see that:

Total volume = 2156*(22/7) / 3

= 2258.67 cm cubed (to two decimal places)

2. Now let's find the total surface area. Let's review the formulas for total surface area for a cylinder and a hemisphere:

Cylinder: SA = 2πr^2 + 2πrh (this is the area of the top and bottom, plus the area of the rectangle that is wrapped around)

However, since the top of the cylinder is covered by the hemisphere, we don't need to count its area in the surface area, thus we must use SA = πr^2 + 2πrh

Hemisphere: SA = πr^2 + 2πr^2 = 3πr^2 (this is the area of the bottom of the hemisphere plus the area of half of the sphere)

However, since the bottom of the hemisphere is on the cylinder, we don't count this in the total surface area either, therefor we must use SA = 2πr^2

Thus, total surface area is given by:

πr^2 + 2πrh + 2πr^2

= 3πr^2 + 2πrh

Now we can substitute the values of the radius and cylinder height into the formula above. So:

TSA = 3πr^2 + 2πrh

TSA = 3π(7)^2 + 2π(7)(10)

= 147π + 140π

= 287π cm squared

Using π = 22/7, we can now see that:

TSA = 287*(22/7)

= 902 cm squared

The answer you are looking for could either be 16 or 40.  To solve the equation, you would follow the steps of PEMDAS. Since the 2 above the equation is an exponent, you'd first solve there.  

Fill in "a" and "b", the equation will now say 2^2 * 3 + 4 = ?. Assuming that the exponent is meant to go with the 2 alone, 2 * 2 = 4. This leaves the equation to say 4 * 3 + 4 = ? Multiply 3 and 4 to get 12, then add 4 to get 16.  

OR  

Fill in "a" and "b". This time, we're assuming that the exponent is going with 2 * 3 (originally 2a). Multiply 2 and 3 to get 6, then square 6 to get 36. Finally, add 4 to 36 to get 40.

To find the inverse of the given function, we need to switch the roles of x and y and solve for y.

To find the inverse of a function, we need to switch the roles of x and y, and then solve for y. So, let's start:

Given f(x) = 4x

Switching the roles, we have x = 4y

Now, solve for y:

x = 4y

Divide both sides by 4:

y = x/4

The inverse function is h(x) = x/4. Therefore, the correct option is h(x) = x/4.

Answer:

(-3, infinity)

Step-by-step explanation:

The domain of the log function is (0, infinity).  In other words, x must be greater than 0.

To determine the domain of f(x) = log2(x + 3) + 2, we set (x + 3) greater than 0 and solve for x:  That set is x > -3, or (-3, infinity).

Answer: 1.125 units

Without the necessary details related to the parallelogram's area or base and side lengths, it is impossible to calculate the precise height of the parallelogram. The snippets provided relate to different mathematical problems and do not apply to the calculation of a parallelogram's height.

To find the height h of the parallelogram, we have several different pieces of information provided in the snippets, and each one appears to address a distinct mathematical problem. However, none of the given pieces align directly with calculating the height of a parallelogram.

To calculate the height of a parallelogram, usually the area and the base length are given, or you would use trigonometric relationships if angles and side lengths are known. Since none of these crucial pieces of information are provided, we will focus on demonstrating a general approach to solve such a problem through a proportion method that was mentioned:

Set up a proportion to find the height of the actual model.

For example, if a scale model uses a 1 cm height to represent 0.5 m in reality, and the actual height in the model is 75 cm, then using the proportion:

Given  : A circle with circumferences = 104 cm , central angle = 45°.

To find :  what is the length of arc AB.

Solution : We have given  circle with circumference = 104 cm , central angle = 45°.

Arc length = [tex]\frac{theta }{360} * circumference[/tex].

 Plug the values circumference = 104 cm , central angle = 45°.

Arc length = [tex]\frac{45 }{360} * 104[/tex].

 Arc length  = 13 cm .

Therefore,  Arc length = 13 cm.

Answer:

26

Step-by-step explanation:

x is a degree so it can't be no more then 60 so the angle should be 26

The value of x is 60 degrees, as determined through a series of geometric deductions based on the properties of triangles and semicircles. Here option B is correct.

The sum of the angles in a triangle is 180 degrees.

The sum of the angles in a semicircle is 180 degrees.

The angle opposite to the diameter of the circle is 90 degrees.

Therefore, the angle x in the first triangle is 180 - 90 - 52 = 38 degrees.

The angle x in the second triangle is 180 - 38 - x = 142 - x degrees.

The angle x in the second triangle is also equal to the angle x in the semicircle, which is 180 - 52 - x = 128 - x degrees.

Equating the two expressions for the angle x in the second triangle, we get 142 - x = 128 - x.

Solving for x, we get x = 60 degrees. Here option B is correct.

The equation of the quadratic graph with a focus of (3, 6) and a directrix of y=4 is (x-3)² = 4(y-5).

Explanation:

To find the equation of a quadratic graph with a focus of (3, 6) and a directrix of y=4, you'll need to use the definition of a parabola. A parabola is the set of all points that are equidistant from a single point, called the focus, and a line, known as the directrix. In this case, since the directrix is horizontal (parallel to the x-axis) and the focus has a y-coordinate greater than the directrix, the parabola opens upwards.

The vertex of the parabola is equidistant from the focus and directrix, so its y-coordinate is halfway between the focus's y-coordinate and the directrix's y-value, which is 5. Because the x-coordinate of the focus is 3, the vertex is at (3, 5). The equation of a parabola in vertex form is (x-h)² = 4p(y-k), where (h,k) is the vertex and 4p is the distance between the vertex and the focus or the vertex and the directrix.

In this problem, the distance p is 1 (since the y-coordinates of the vertex and focus differ by 1). Thus, the equation of the parabola is (x-3)² = 4(y-5). This is the standard quadratic form for a parabola opening upwards with vertex at (3, 5) and focus at (3, 6).

Answer:

no real solution is the answer

If you have to list your extraneous solutions somewhere, that would be x=0.

Step-by-step explanation:

Cool thing here is the radical, the thing with the square root, is already isolate.

So we need to square both sides as a first step.  (Whenever you raise both sides to even power, you must definitely check your solutions as some might not actually be solutions to the original equation)

So upon squaring both sides I get:

x^4+16=(x^2-4)^2

Now I will write (x^2-4)^2 as (x^2-4)(x^2-4) and foil it!  This gives me:

x^4+16=x^4-8x^2+16

Subtract x^4 and 16 on both sides:

       0=-8x^2

Divide both sides by -8

      0=x^2

Therefore x=0.

0 isn't actually a solution though because when you plug it in you get 4=-4 which is not true.
