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

Find the inverse of function f.
f(x) = 1/3 - 1/21x
Answers
Answer:f⁻ (x) = 7 - 21 x.
We can also write it as:
y = 1/3 - 1/21 x
1 / 21 x = 1 / 3 - y
x = 7 - 21
To find the inverse of the function f(x) = 1/3 - 1/21x, interchange x and y in the equation, solve for y, and denote it as the inverse function, resulting in [tex]f^-1(x) = 7 - 21x[/tex].
The student is asking to find the inverse of the function f(x) = 1/3 - 1/21x. To find the inverse function, we need to first rewrite the function in the form y = 1/3 - 1/21x. Next, we switch x and y to get x = 1/3 - 1/21y. Then, solve for y, giving us the inverse. The steps are:
Replace f(x) with y: y = 1/3 - 1/21xInterchange x and y: x = 1/3 - 1/21yMultiply both sides by 21 to clear the fraction: 21x = 7 - yAdd y to both sides and subtract 7 from both sides: y + 21x = 7Isolate y: y = 7 - 21xFinally, replace y with f-1(x) to denote the inverse function:f-1(x) = 7 - 21x

find the area of that shape please and show work
Answers
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.

What is the area of the circle whose diameter is 16 ft?
201.1 sq ft
802.2 sq ft
50.3 sq ft
Answers
Answer:
Step-by-step explanation:
The area of a circle is
[tex]A=\pi r^2[/tex]
We are given the diameter, but need the radius. The radius is half the diameter, so the radius is 8 feet. Plugging into the formula and using 3.14 for π:
A = (3.14)(64) so
A = 200.96 sq feet which rounds to 201. I guess that's the first choice there, but not quite exact...
Final answer:
The area of the circle with a diameter of 16 ft is (Option A) 201.1 sq ft.
Explanation:
The area of a circle can be found using the formula A = πr², where A is the area and r is the radius. However, in this case, we are given the diameter instead of the radius. The diameter is twice the length of the radius, so we can calculate the radius by dividing the diameter by 2. Given that the diameter of the circle is 16 ft, the radius would be 16/2 = 8 ft.
Now, we can use the formula A = πr² to find the area. Plugging in the radius value, we get A = π(8 ft)² = π(64 ft²) ≈ 201.1 sq ft.

The ratio of the surface areas of the cone shown is 16 : 9.
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
Given are two cones.
Also given that,
Ratio of the radii of the cones = 4 : 3
It is given that both cones are similar figures.
So scale factor = 4/3
Surface area of a cone = πr² + πr√h²+r²
Now the surface area is proportional to the square of the radii of the cone.
So ratio of surface area = 4² / 3² = 16 / 9
Hence ratio of the surface area of the cones is 16 : 9.

Answers
Answer:

Step-by-step explanation:
3000+3600=6600
Answer:
Their total budget was $42000 last year.
Step-by-step explanation:
8% = 0.08
1.) 0.08( x + 3000 ) = 3600
2.) Distribute:
0.08x + 240 = 3600
3.) Use inverse operation to solve. Subtract 240 from each side:
0.08x + 240 = 3600
- 240 = - 240
0.08x = 3360
3.) divide 0.08 from each side:
0.08x = 3360
x = 42000

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.

What is the area?The area of a two - dimensional figure is the area that its perimeter encloses. The quantity of unit squares that occupy a closed figure's surface is its region.
The top two nets are triangular prisms connected to the bases of a rectangular prism. The composite image is made up of all three prisms. The dark sections represent faces shared by the prisms.
The total surface area of the composite figure is calculated as,
A = 4(1/2 x 3 x 4) + 2(5 x 10) + 2(4 x 10) + 2(3 x 3) + 2(3 x 10)
