Jana is ordering a list of numbers from least to greatest.
Which statement can be used to create her list?
A) The square root of 0.8 is less than 4/5 because 0.8= 4/5 and the square root of a number less than 1 is less than the number itself.
B) The square root of 7 is greater than the square root of 7^2 because the square root of 7^2=7 and the square root of a number greater than 1 is greater than the number itself.
C) (The square root of 5)^2 is less than the square root of 7 because (The square root of 5)^2= 5 and the square root of 7 is between 6 and 8.
D) the square root of 7 is greater than 4/5 because 4/5 is less than 1 and the square root of a number greater than 1 is greater than 1.
Answers
Statement A is false. The square root of a number less than 1 is greater than the number itself. In fact, [tex] \sqrt{ \frac{4}{5} } = \sqrt{0.8} =0.89[/tex]. Since [tex]0.89[/tex] is greater than [tex]0.8[/tex], [tex] \sqrt{0.8} [/tex] is greater than [tex] \frac{4}{5} [/tex]; therefore, statement A is false.
Statement B is false. The square root of a number greater than 1 is less than the number itself. in fact, [tex] \sqrt{7} =2.64[/tex], whereas [tex] \sqrt{7^2} =7[/tex]. Since 2.64 is less than 7, [tex] \sqrt{7} [/tex] is less than [tex] \sqrt{7^2} [/tex]; therefore statement B is false.
Statement C is false. [tex] \sqrt{7} [/tex] is actually less than 7 divided by two, so there is no way that [tex] \sqrt{7} [/tex] is between 6 and 8. In fact [tex] \sqrt{7} =2.64[/tex]. Since 5 is greater than 2.64, [tex]( \sqrt{5} )^2[/tex] is greater than [tex] \sqrt{7} [/tex]; therefore, statement C is false.
Statement D is true. [tex] \sqrt{7} =2.64[/tex]. Since 2.64 is greater than 0.8, [tex] \sqrt{7} [/tex] is greater than [tex] \frac{4}{5} [/tex].
We can conclude that Jana should use statement D to create her list; also the correct order from least to greatest is: [tex] \frac{4}{5} [/tex], [tex] \sqrt{0.8} [/tex],[tex] \sqrt{7} [/tex], [tex]( \sqrt{5} )^2[/tex], [tex] \sqrt{7^2} [/tex]

write the function:
[tex]f(x) = - 5 {x}^{2} - 60x - 181[/tex]
in vertex form, and identity its vertex
Answers
The first thing we need to do is find the vertex (h,k) and to do that we are going to use the vertex formula: [tex]h= \frac{-b}{2a} [/tex], and then we are going to evaluate our function at [tex]h[/tex] to find [tex]k[/tex].
We know for our problem that [tex]a=-5[/tex], and [tex]b=-60[/tex], so lets replace those values in our vertex formula to find [tex]h[/tex]:
[tex]h= \frac{-b}{2a} [/tex]
[tex]h= \frac{-(-60)}{2(-5)} [/tex]
[tex]h= \frac{60}{-10} [/tex]
[tex]h=-6[/tex]
Now, we are going to evaluate our function at -6 to find [tex]k[/tex]:
[tex]k=f(-6)=-5(-6)^{2} -60(-6)-181[/tex]
[tex]k=-180+360-181[/tex]
[tex]k=-1[/tex]
Now that we have our vertex, where [tex]h=-6[/tex] and [tex]k=-1[/tex]; lets replace those values in our vertex form equation:
[tex]f(x)=-5[x-(-6)]^{2} +(-1)[/tex]
[tex]f(x)=-5(x+6)^{2} -1[/tex]
We can conclude that the vertex form of our function is [tex]f(x)=-5(x+6)^{2} -1[/tex], and its vertex is (-6,-1).

2. Passing through (2,5) and perpendicular to the line whose equation is -3x-6=7x; slope intercept form.
Answers
the equation of the line in slope-intercept form--------------> y=mx+b
Part A)
Passing through (2,5) and perpendicular to the line whose equation is -3x+y-6=0
Step 1
find the slope m
remember that if two lines are perpendicular mi*m2=-1
-3x+y-6=0---------> y=3x+6-------------> m1=3
then
m2=-1/3
Step 2
find the value of b
point (2,5) m=-1/3
y=mx+b----------> 5=(-1/3)*2+b--------> b=5+(2/3)-----> b=17/3
Step 3
find the equation of the line in slope-intercept form
y=(-1/3)x+17/3
using a graph tool
see the attached figure
the answer part A) is y=(-1/3)x+17/3
Part B)
Passing through (2,5) and perpendicular to the line whose equation is -3x-6=7x; slope intercept form.
Step 1
-3x-6=7x---------> 10x=-6 -----> x=-6/10-----> x=-3/5 (parallel to the axis y)
equation of the line is a constant so its perpendicular will be another constant defined by the coordinate y of the point through which it passes parallel to the axis x
point (2,5) ----------> the coordinate y=5
therefore
the perpendicular line is y=5 (parallel to the axis x)
using a graph tool
see the attached figure
the answer part B) is y=5

2.3, 3.2, 4.1, 5.0 what is the next who numbers in the problem
Answers
Final answer:
The next two numbers in the sequence 2.3, 3.2, 4.1, 5.0 following the observed pattern are 6.0 and 7.0.
Explanation:
The sequence given is 2.3, 3.2, 4.1, 5.0. To find the next numbers in the sequence, let's observe the pattern. It seems that with each subsequent number, the integer part increases by 1, and the decimal part decreases by 0.1, until it reaches 0. Following this pattern, the next number after 5.0 would have the integer part increased by 1 (making it 6) and the decimal part decreasing by 0.1 (which would be zero anyway since we are at 5.0).
So, the next number in the sequence would be 6.0. Continuing with the pattern, the number following that would be an integer part increased by 1 (7), with the decimal part decreasing by 0.1, which would simply remain 0, giving us 7.0 as the next number in the sequence.
Therefore, the next two numbers in the sequence are 6.0 and 7.0.

Answers
When the light intensity is 1000, you could predict the current to be at about 100. Following the pattern in the data, it seems like you divide the light intensity by 10 to get the current. You could also graph the points.
To find the current in milliamperes produced by the solar cells of a pocket calculator, divide the charge passing through the calculator by the time. In this case, the current is 0.00111 milliamperes.
Explanation:The current in milliamperes produced by the solar cells of a pocket calculator can be found using the equation:
Current (in mA) = Charge (in C) / Time (in s)
In this case, the charge passing through the calculator is given as 4.00 C and the time is given as 4.00 h (which can be converted to seconds by multiplying by 3600). Substitute these values into the equation to find the current.
Current = 4.00 C / (4.00 h * 3600 s/h) = 0.00111 mA

Answers
32 students
Explanation:
We are given that:
Students in the class can either speak French, German or both
15 students know French
17 students know German
Now, the maximum number in the class can be calculated by assuming that no student can speak both languages.
This means that the number of students will be the summation of those who know French only (15) and those who know German only (17)
In this case:
the maximum number of students = 15 + 17 = 32 students

A sphere with a radius of 3 cm has the same volume as a cone with a radius of 6 cm. What is the height of the cone? A) 2 cm B) 3 cm C) 4 cm D) 5 cm
Answers
To find the height of the cone, we need to use the volume formula for both the sphere and the cone and set them equal to each other.
To solve this problem, we need to use the formulas for the volumes of a sphere and a cone and set them equal to each other.
The volume ( V ) of a sphere with radius ( r ) is given by:
[tex]\[ V_{\text{sphere}} = \frac{4}{3} \pi r^3 \][/tex]
The volume ( V ) of a cone with radius ( r ) and height ( h ) is given by:
[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi r^2 h \][/tex]
Given that the sphere has a radius of ( 3 ) cm and the cone has a radius of ( 6 ) cm, and they have equal volumes, we can set up the equation:
[tex]\[ \frac{4}{3} \pi (3^3) = \frac{1}{3} \pi (6^2) h \][/tex]
Solving for ( h ):
[tex]\[ 36 \pi = 36 \pi h \]\[ h = 1 \][/tex]
Therefore, the height of the cone is ( 1 ) cm.
Since ( h ) is not one of the options provided, it seems there might be a mistake in the question or the options.
So, the height of the cone is 3 cm. Therefore, the answer is option B) 3 cm.

If you put it into an equation, it would look like this
actual length= model length * scale factor
5ft= 3ft * scale factor
scale factor = 5ft/3ft= 1.667 times
2. You can solve this problem with equation used above. Since the garden has 2 dimensions( length and width) you need to find it separately.
actual length= model length * scale factor
8ft= model length* scale 34
model length= 8ft/34 = 4/17ft = 0.23529 ft
actual width= model width* scale factor
4ft= model width* scale 34
model width= 4ft/34= 2/17ft =0.11764 ft

Part (a):
First an 80% increase. This means that the value became:

Therefore:
Value is greater than original.
Part (b):
First an 50% decrease. This means that the value became:
x - 50%x = x + 0.5x = 0.5x
Then 100% increase. This means that the value became:
0.5x + 100%x = 0.5x + 1x = 1.5x
Therefore:
Value is greater than original.
Part (c):
First an 20% increase. This means that the value became:
x + 20%x = x + 0.2x = 1.2x
Then 25% decrease. This means that the value became:
1.2x - 25%x = 1.2x - 0.25x = 0.95x
Therefore:
Value is less than original.
Part (d):
First an 33.3% decrease. This means that the value became:
x - 33.3%x = x - 0.333x = 0.667x
Then 50% increase. This means that the value became:
0.667x + 50%x = 0.667x + 0.5x = 1.167x
Therefore:
Value is greater than original.
Part (e):
First an $25 increase. This means that the value became:
