The volume of a sphere with a radius of 4 feet, to the nearest hundredth is: 268.08 cubic feet.

Volume of a sphere, where r is the radius of the sphere, is determined using the formula, V = 4/3 × π × r³.

Given the radius of the sphere is 4 feet

Volume of the sphere = 4/3 × π × r³ = 4/3 × 3.14 × 4³

Volume of the sphere = 268.08 ft³

Therefore, the volume of a sphere with a radius of 4 feet, to the nearest hundredth is: 268.08 cubic feet.

Answer:

I'd times the first equation by 3 and the second equation by 2. Giving:

6x + 15y = 21

6x + 8y = 12

then I'd subtract the second from the first

6x-6x + 15y-8y = 21-12

7y = 9

y = 7/9

then sub y into one of the equations and solve for x.

Answer:

Step-by-step explanation:

Solving simultanius equation by elimination

2x + 5y = 7 -------------(I)

3x + 4y = 6 ---------------(II)

To eliminate x, multiply equation (I) by (-3) and equation (II) by 2. Then add the two equations. Now, 'x' will be eliminated and we can find the value of 'y'.

(I) *(-3)             -6x  - 15y = -21

(II)*2                 6x +  8y  = 12    {Now add}              

                               - 7y  = -9

                                   y = -9/-7

y = 9/7

The quadratic function can be represented by a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.

The vertex of an up-down facing parabola of the form ax²+bx+c is [tex]x_v=\frac{-b}{2a}[/tex]  . Knowing the x-coordinate of vertex, you can find the y-coordinate of vertex. When a vertical line passes through the vertex of the parabola, it  is called the axis of symmetry.

The y-intercept is the point where the function crosses the y-axis. And, the x-intercept is the point where the function crosses the x-axis, in other words, when y=0.

First, you should convert the given equation to Standard form.

f(x) = -(c+7)² + 4

f(x)= - (c²+14c+49)+4

f(x)= -c²-14c-49+4

f(x)= -c²-14c-49+4

f(x)= -c²-14c-45

After that, you should check each option of the question.

Correct because present a degree 2 -- f(x)= -c²-14c-45

Incorrect because it is a quadratic function and this function is represented by a parabola.

The coefficients are: a=-1, b=-14, c=-45. Therefore,

[tex]c_v=\frac{-b}{2a}=-\frac{-14}{2*(-1)} =-\frac{-14}{-2}=-(7)=-7[/tex]

Incorrect because x-coordinate of vertex is -7

Correct because  [tex]c_v=\frac{-b}{2a}=-\frac{-14}{2*(-1)} =-\frac{-14}{-2}=-(7)=-7[/tex]

You can find the y-intercept using c=0, then f(x)= -c²-14c-45 will be:

f(x)=-45.

Incorrect because the y-intercept is (0,-45).

The coefficient a of a quadratic function is negative, thus the function has a point maximum. A relative maximum point is defined as the point where the function changes your direction. In other words, the values of the function increase before the relative maximum and the values decrease after the relative maximum.

Correct, see the attached image.

It is possible to find the number of roots or solutions from discriminant.

For quadratic equation the discriminant is determined by D=b²-4ac, where: a, b and c are coefficients.

If D > 0 - the function will have two real solutions;

If D = 0 - the function will have one real solution;

If D < 0 - the function will have imaginary solutions;

For given equation, the coefficients are: a=-1, b=-14, c=-45. Thus, D=(-14)²-4*(-1)*(-45)

D=196-180=16

D=16 thus D > 0

Incorrect because the D>0.

Step-by-step explanation:

The sample ad 600 chips. They wanted to test 36000 chips. 600*60=36000

If 22 out of 600 chips were defective, and 600*60=36000

Then 1320 chips were defective out of the 36000 because 22*60=1320.

The following solution is arrived at by using the formula for the area of a regular octagon in relation to its Apotem which in this case is 18. Hence the area of the Octagon given is 1,446.

An apothem is defined as a line from the center of a regular polygon at right angles to any of its sides.

The calculation for this shape using only it's apothem has some curved bends. In order to derive the area, we have to divide the octagon into triangles.

When we find the area of the triangles we can then multiply by the total number to get the area of the Octagon.

Hence we can say that the area of the Octagon (A) = (1/2b*h)n

Where b = base

           h = height

           n = number of triangles.

Recall that the total angle in a circle is 360°, hence given that all the triangles are equal, we must divide 360° by  8 triangles to get the angle in the vertex of each triangle.

Thus, 360°/8 = 45°

So we have The angle of our triangle which is opposite the base.

Recall that the triangle is split in two so that each of the triangles are right-angled triangle,

Hence, the angle opposite the base for each right angle triangle is given as:

45°/2 = 22.5°

So to get the length of the opposite side (x), we use the law of tangents:

Which means:

x = 18 Tan 22.5°

= 18 * 0.55785173935

≈ 10.04

So if x is ≈ 10.04, then area of that triangle is

= 1/2 * 10.04 * 18 (that is 1/2bh)

= 90.3792

From the above, we can state that the Area of the triangle with the Apothem is

= 90.3792 * 2

= 180.74

Recall our formula for finding the area of the octagon:

A = (1/2bh)n

A = (108.74) *8

A = 1,445.95

≈ 1,446

18 Days Off

Step-by-step explanation:

Firstly, to solve this question you have to identify how many months are in a year; that's 12. So now we know:

Making a formula for calculation is the best way to do this, especially since we now have all of the information needed to answer.

VacationDays=1 [tex]\frac{1}{2}[/tex] × 12

Vacation days are the total number of vacation days in a year.

∴VD= 1 [tex]\frac{1}{2}[/tex] x 12

VD= 18

∴Total vacation days equal 18

Each employee gets 18 vacation days in a year.

The expression indicated that the values of a will be between 4.01 and 4.99 and b will be between 2.01 and 3.99.

From the first expression, 4 < a < 5. This means that 4 is less than a and a is less than 5. This means the values of a will be between 4.01 and 4.99.

Also, 2 < b < 4. This means that 2 is less than b and b is less than 4. Therefore, the values of b will be between 2.01 and 3.99.

The equation of the line that is perpendicular to y = 4x + 5, in slope-intercept form is: y = -1/4x - 2.

Lines that are perpendicular to each other have slope that are negative reciprocal to each other.

Slope of y = 4x + 5 is 4.

Negative reciprocal of 4 is -1/4.

Substitute m = -1/4 and (a, b) = (8, -4) into y - b = m(x - a):

y - (-4) = -1/4(x - 8)

y + 4 = -1/4x + 2

y = -1/4x + 2 - 4

y = -1/4x - 2

Equation of the perpendicular line is: y = -1/4x - 2.
