Answer: 288π in³
Step-by-step explanation: To find the volume of a sphere, start with the formula for the volume of a sphere which is [tex]v =\frac{4}{3} \pi r^{3}[/tex].
Here, we are given that our sphere has a radius of 6 inches.
So plugging into the formula, we have [tex](\frac{4}{3})(\pi)(6 in.)^{3}[/tex].
Start by simplifying the exponent.
(6 in.)³ is equal to 6 inches · 6 inches · 6 inches or 216 in³.
So we have [tex](\frac{4}{3})(216 in^{3})(\pi)[/tex].
Notice that we can cross cancel 3 and 216 to 1 and 72.
So we have (4)(72in³)(π) which is equal to 288π in³.
So the volume of the sphere is 288π in³.
Solve for u:
-10.74=u-(−11)
Answer:
-21.74
Step-by-step explanation:
-10.74 = u + 11
-10.74 - 11 = u + 11 - 11
-21.74 = u
u = -21.74

Answer:
[tex]\frac{13\pi}{9}[/tex]radian
Step-by-step explanation:
We are given that
[tex]\theta=260^{\circ}[/tex]
We have to convert angle into radian.
We know that
Radian measure=[tex]\frac{\pi}{180}\times degree\;measure[/tex]
Using the formula then we get
Radian measure=[tex]\frac{\pi}{180}\times 260[/tex]
Radian measure=[tex]\frac{13\pi}{9}[/tex]radian
Hence, 260 degree=[tex]\frac{13\pi}{9}[/tex]radian

find the area of that shape please and show work
Given:
AB = 9 in, BC = 2 in
DE = 3 in, EF = 3 in
To find:
The area of the shape
Solution:
ABCH is a rectangle.
Area of rectangle = length × width
= AB × BC
= 9 × 2
Area of ABCH = 18 in²
GDEF is a square.
Area of square = side × side
= DE × EF
= 3 × 3
Area of GDEF = 9 in²
Area of the shape = Area of ABCH + Area of GDEF
= 18 in² + 9 in²
= 27 in²
The area of the shape is 27 in².

1. Solve by setting the linear factors equal to zero.(x+4)(x-3) = 0
a) x = 4 and x = -3
b) x = 2 and x = 1
c) x = -4 and x = 3
d) x = -2 and x = 1
Answer:
C - x = -4 and x = 3
Step-by-step explanation:
Set (x+4) = 0
x = -4
set (x-3)=0
x=3
Answer:
c) x = -4 and x = 3
Step-by-step explanation:
(x+4)(x-3)=0
x+4=0 ( You want to find the x value, so we subtract 4 for both sides to get rid of +4)
x +4 -4 = 0 -4
x = -4
x-3=0 ( The same thing, but add 3 either side to get rid of -3 )
x-3 +3 = 0+3
x= 3
What is the value of log Subscript 3 Baseline 81?
2
3
4
5
Answer:
4
Step-by-step explanation:
Using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇔ x = [tex]b^{n}[/tex]
Given
[tex]log_{3}[/tex] 81 = n, then
81 = [tex]3^{n}[/tex]
Note that 81 = [tex]3^{4}[/tex] , thus
[tex]3^{4}[/tex] = [tex]3^{n}[/tex]
Since the bases are equal then equate the exponents
n = 4
The value of log Subscript 3 Baseline 81 (i.e Log₃ 81) obtained is 4
Data obtained from the question Log₃ 81 =? How to determine the value of Log₃ 81Let Log₃ 81 be equal to n i.e
Log₃ 81 = n
The value of n can be obtained as follow:
Log₃ 81 = n
81 = 3ⁿ
Express 81 in index form with 3 as the base
3⁴ = 3ⁿ
Cancel out 3
n = 4
From the calculation made above, we can conclude that the value of log Subscript 3 Baseline 81 (i.e Log₃ 81) is 4

Final answer:
The quadratic trinomial x² - 10x + 4.75 is solved using the quadratic formula. The coefficients identified are a=1, b=-10, and c=4.75, and when substituted into the formula, it yields solutions x = 7 and x = 3.
Explanation:
Solving a Quadratic Equation Using the Quadratic Formula
To solve the quadratic trinomial x2−10x + 4.75 using the quadratic formula, 'x' equals minus 'b', plus-or-minus the square root of 'b' squared minus four 'a' 'c', all over two 'a', we first identify the coefficients a, b, and c from the trinomial, which are in the standard form of ax2 + bx + c = 0.
Identifying coefficients: a = 1 (the coefficient of x²), b = -10 (the coefficient of x), c = 4.75 (the constant term).
Plugging the coefficients into the quadratic formula: x = −(-10) ± √((-10)2 − 4(1)(4.75)) / (2(1)).
Calculating the discriminant: Calculate b2 − 4ac which is 100 − 19.
Square root step: Take the square root of the discriminant, which is √81.
Final calculation: Compute the two possible values for x which are x = 5 + √81 / 2 and x = 5 − √81 / 2.
Solution: The roots are x = 5 + 9/2 and x = 5 − 9/2, simplifying to x = 7 and x = 3.
The final answer for the roots of the equation x² − 10x + 4.75 = 0 using the quadratic formula are x = 7 and x = 3.

The median and interquartile range is used as a measure of center and measure variability to compare populations when:
When there are outliers in the data sets
When there are no big gaps in the middle of the data sets
When the plots representing the data are symmetrical
When there are no outliers in the data set
We have,
Use the median and interquartile range as measures of center and variability to compare populations shown on a box plot in the following scenarios:
- When there are outliers in the data sets:
The median and interquartile ranges are resistant to outliers, meaning they are not significantly influenced by extreme values.
- When there are no big gaps in the middle of the data sets:
The median is a measure of the center that is not affected by extreme values or outliers, making it appropriate when there are no significant gaps or clusters in the middle of the data sets.
The interquartile range, which measures the spread of the central 50% of the data, is also less influenced by extreme values compared to the range or standard deviation.
- When the plots representing the data are symmetrical:
The median is a suitable measure of center for symmetrical distributions, where the data is evenly distributed around the middle.
In such cases, the median provides a representative measure of the central tendency.
The interquartile range also captures the spread of the data within the central 50% and can be used as a measure of variability.
- When there are no outliers in the data set:
While the median and interquartile ranges are resistant to the influence of outliers, they can still be used effectively to compare populations when no outliers are present.
In the absence of outliers, the median accurately represents the central tendency, and the interquartile range provides a robust measure of variability.
Therefore,
