We are told that

x

is the set of numbers such that the distance

Either +(x-4) = 8 -> x=12#

Or -(x-4) = 8 -> x=-4#

Hence,setx = { =4,12 }

A baseball has a 15 cm diameter what is the voulme of the contents of the ball
ddd [48]

Answer:

The answer is 1767.15cm^3

Step-by-step explanation:

The formula for finding the volume of a spherical object is 4/3(π)(r^3),where r is the radius of the object. But here only the diameter was given. And diameter=2(r), where r is radius.

So to find the radius, divide the diameter by 2. Since by making r the subject of the equation you get r=diameter/2.

Using the formula

4/3(π)(r^3)=(4π((15/2)^3))/3

=(4π(7.5^3)/3

=(4π(421.875))/3

Since π is 3.141592654

(4π(421.875))/3=1/3(4(3.141592654)(421.875))

=1/3(5301.437603)

=1767.145868

But I rounded off the answer to 2 decimal places and so I got 1767.14

What is the sum of (3x^2+ 5x +6) and (25x^3+ 10x² + 7x– 3)
muminat

Answer:

25x³ + 13x² + 12x + 3

Step-by-step explanation:

(3x²+ 5x +6) + (25x³ + 10x² + 7x– 3)

3x²+ 5x + 6 + 25x³+ 10x² + 7x – 3

25x³ + 3x² + 10x² + 5x + 7x + 6 - 3

25x³ + 13x² + 12x + 3

determine whether each statement is always, sometimes, or never true. an absolute value function of the form f(x)=/x+a/+b has ex
Ksivusya [100]

<u>Answer-</u>

<em>The statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.</em>

<u>Solution-</u>

It solely depends on b, whether the function will have one or two or zero x intercept.

This plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e V shape, with vertex translated to (-a, b), instead of origin.

1-  If b is zero, the graph will have exactly one x-intercept, at x= -a

2- If b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- If b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ The statement is sometimes true.
