Find the m/1

(9x - 5)
1
(4x + 10)°
Answers
Answer:
∠ 1 = 158°
Step-by-step explanation:
(9x - 5) and (4x + 10) are vertically opposite angles and are congruent, so
9x - 5 = 4x + 10 ( subtract 4x from both sides )
5x - 5 = 10 ( add 5 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
then
4x + 10 = 4(3) + 10 = 12 + 10 = 22°
∠ 1 and (4x + 10) are a linear pair and sum to 180° , that is
∠ 1 + 22° = 180° ( subtract 22° from both sides )
∠ 1 = 158°

The number of mosquitoes will be increased by 5 inches of rain.
Maximum mosquito population = 25000
solution :We are given the following in the question:
M(x) = 10x - x²
where M(x) denotes the number of mosquitos in millions and x denotes the amount of rainfall in inches.
To begin, we differentiate M(x) with respect to x, yielding
d(M(x)) /dx = d(10x - x²) /dx = 10 -2x
When we set the first derivative to zero, we get
d(M(x)) /dx = 0
10 - 2x = 0
x = 5
We get the same result when we differentiate M(x) with respect to x:
d²(M(x)) / dx² = -2
d²(M(x)) / dx² < 0
As a result of the double differentiation test, the maxima for M(x) occur at x = 5.
when the rainfall is 5 inches, the most mosquitoes are present.
Maximum mosquito population:
M(5) = 10(5) - (5)² = 25
As a result, the maximum number of mosquitos is 25000.

area = 5 1/3 square units
Step-by-step explanation:
You want the area under the square root curve, above y=0, from x=0 to x=4.
AreaThe area is found by integrating a differential of area over appropriate limits. A vertical slice will have hight √x and width dx, so we have ...
dA = (√x)dx
A = ∫(√x)dx
The power rule can be used for the integration:
\(\displaystyle A=\int_0^4{x^{\frac{1}{2}}}\,dx=\left[\dfrac{x^{\frac{3}{2}}}{\frac{3}{2}}\right]^4_0=\dfrac{2}{3}(4^\frac{3}{2})=\dfrac{16}{3}=\boxed{5\dfrac{1}{3}}\)
The area of the region is 5 1/3 square units.
__
Additional comment
You will notice that the area is bounded by a rectangle 4 units wide and 2 units high, for an area of 4·2 = 8. The area under the parabolic curve is 2/3 of that: 2/3·8 = 16/3 = 5 1/3 square units.
This fraction will be true for any area bounded by a parabola where the vertex is one of the corners of the rectangle.

A wooden lead pencil is in the shape of a cylinder. The pencil is 21 cm long with radius 0,4 cm and its lead is of radius 0,1 cm. What is the volume of wood in the pencil? 1.9.0 cm³ 2.9.4 cm³ 3.9.9 cm³ 4.10.1 cm³
Answers
Answer:
Answer3. 9.9cm^3
Step-by-step explanation:
First calculate the volume of the whole pencil. Next, calculate the volume of the lead. Last, subtract. Take away the volume of the lead from the volume of the pencil:
VolWood =
VolPencil - VolLead
First, Volume of the pencil:
vol = pi•r^2•h
= 3.14•(.4)^2•21
= 10.5504 cm^3
Next, volume of lead:
vol = pi•r^2•h
= pi•(.1)^2•21
= .6594cm^3
Last, subtract:
VolWood =
VolPencil - VolLead
= 10.5504 - .6594
= 9.891
~= 9.9cm^3
The volume of the wood is 9.9cm^3.
A box with an open top has a square base and four sides of equal height. The volume of the box is 288 ft^3. The height is 2 ft greater than both the length and the width. If the surface area is 228 ft^2, what are the dimensions of the box? What is the width (and length) of the box?
Answers
The dimensions of the box is 6 ft by 6 ft by 8 ft. The width (and length) of the box is 6 ft.
Let x = width (and length) of the box
If the height is 2 ft greater than both the length and the width, then
x + 2 = height of the box
If the surface area is 228 ft², then
SA = (l x w) + 2(l x h) + 2(w x h)
228 ft² = x(x) + 2(x)(x + 2) + 2(x)(x + 2)
Simplify the equation.
228 = x² + 2x² + 4x + 2x² + 4x
228 = 5x² + 8x
5x² + 8x = 228
Get the positive root(s) of the equation.
(5x + 38)(x - 6) = 0
x = 6
width (and length) of the box = 6 ft
height of the box = x + 2 = 8 ft
Check the volume of the box.
V = l x w x h
288 = 6 x 6 x 8
288 = 288
Hence, the dimensions of the box is 6 ft by 6 ft by 8 ft.

Part B: Calculate the measures of variability. Show all work. (5 points)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (2 points)
7
Answers
To find the measures of center, we need to determine the median for each school.
For Sky View School:
Arrange the data in order: 0, 0, 1, 2, 3, 4, 5, 5, 5, 6, 7, 7, 8, 9
The median is the middle value, which is 5.
For South Lake School:
Arrange the data in order: 0, 0, 1, 2, 2, 5, 6, 6, 8
The median is the middle value, which is also 5.
Therefore, the median class size for both schools is 5.
Part B: Measures of variability
To find the measures of variability, we need to determine the range and interquartile range (IQR) for each school.
For Sky View School:
The smallest value is 0 and the largest value is 9, so the range is 9 - 0 = 9.
To find the IQR, we need to find the first and third quartiles. The median is 5, so the first quartile is the median of the lower half, which is (0 + 1 + 2 + 3 + 4)/5 = 2. The third quartile is the median of the upper half, which is (6 + 7 + 8 +9)/4 = 7.25 (rounded to two decimal places).
Therefore, the IQR is 7.25 - 2 = 5.25.
For South Lake School:
The smallest value is 0 and the largest value is 8, so the range is 8 - 0 = 8.
To find the IQR, we need to find the first and third quartiles. The median is 5, so the first quartile is the median of the lower half, which is (0 + 0 + 1 + 2)/4 = 0.75 (rounded to two decimal places). The third quartile is the median of the upper half, which is (6 + 6 + 8)/3 = 6.67 (rounded to two decimal places).
Therefore, the IQR is 6.67 - 0.75 = 5.92 (rounded to two decimal places).
Part C: Choosing a school based on class size
If you are interested in a smaller class size, South Lake School is the better choice. This is because the range and IQR for South Lake School are smaller than those for Sky View School, indicating that the class sizes at South Lake School are more consistent and less variable. Additionally, the largest class size at South Lake School is 8, while the largest class size at Sky View School is 9, further indicating that South Lake School may have smaller class sizes overall.
Measures of center for Sky View School:
Mean = (0+1+2+3+4+5+5+5+6+7+7+8+9)/13
Mean = 4.8
Median = 5
Measures of center for South Lake School:
Mean = (0+1+2+2+3+5+6+6+8+8)/10
Mean = 4.1
Median = 5
Part B:
Measures of variability for Sky View School:
Range = 9 - 0 = 9
Interquartile Range (IQR) = Q3 - Q1 = 7 - 2 = 5
Variance = [(0-4.8)^2 + (1-4.8)^2 + (2-4.8)^2 + (3-4.8)^2 + (4-4.8)^2 + (5-4.8)^2 + (5-4.8)^2 + (5-4.8)^2 + (6-4.8)^2 + (7-4.8)^2 + (7-4.8)^2 + (8-4.8)^2 + (9-4.8)^2]/12
Variance = 7.6
Standard Deviation = √7.6
Standard Deviation = 2.76
Measures of variability for South Lake School:
Range = 8 - 0 = 8
Interquartile Range (IQR) = Q3 - Q1 = 6 - 1 = 5
Variance = [(0-4.1)^2 + (1-4.1)^2 + (2-4.1)^2 + (2-4.1)^2 + (3-4.1)^2 + (5-4.1)^2 + (6-4.1)^2 + (6-4.1)^2 + (8-4.1)^2 + (8-4.1)^2]/9
Variance = 6.45
Standard Deviation = √6.45
Standard Deviation = 2.54
Part C:
If you are interested in a smaller class size, South Lake School is a better choice for you. This is because the measures of center and variability for South Lake School are both smaller than those for Sky View School.

Halla x si:
a) 4√5 b) √5 c) 4√3 d) 4 e) 4√2
Answers
Answer:
Option A. 4√5
Step-by-step explanation:
To obtain the value of x, we must first obtain the value of y as shown in the attached photo.
The value of y can be obtained by using the pythagoras theory as illustrated below:
In this case y is the longest side i.e the Hypothenus.
y² = 4² + [4√3]²
y² = 4² + [4² × (√3)²]
y² = 4² + [4² × 3]
y² = 16 + [16 × 3]
y² = 16 + 48
y² = 64
Take the square root of both side
y = √64
y = 8
Finally, we shall determine the value of x by using the pythagoras theory as illustrated below.
Note: x is the longest side i.e the Hypothenus in this case.
x² = 4² + 8²
x² = 16 + 64
x² = 80
Take the square root of both side
x = √80
x = √(16 × 5)
x = √16 × √5
x = 4√5
Therefore, the value of x is 4√5.
