Use the given conditions to write and equation for the line in the indicates form:
1. Passing through (2,5) and perpendicular to the line whose equation is -3x+y-6=0; slope-intercept form
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
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).
2.3, 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.

2. A rectangular garden has a length of 8 ft and a width of 4 ft. A smaller garden was made, using a scale factor of 34 . Find the dimensions of the smaller garden. Enter your answers in the boxes.
Answers
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
Answer:
3 / 5 = 0.6 so the scale factor is 0.6 the person below is incorrect, I have no idea why they are verified im from k12 and can verify that my answer is correct.

If you want to do this yourself, you can use the Law of Sines to find angle C.
.. C = arcsin(7.1/15*sin(67°)) ≈ 25.8302° . . . . don't round intermediate values
Then angle B is 180° -67° -angle C = 87.1698°

In a class, every student knows French or German (or both). 15 students know French, and 17 students know German.
What is the largest possible number of students in that class?
PLZ ANSWER AND SHOW WORK?
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

Answer:
Area of hexagonal pyramid = 113.57 unit²
Step-by-step explanation:
Area of hexagonal pyramid = Area of base + Area of six triangular slanting face.
Area of base = 6 x Area of equilateral triangle with side 4.
[tex]\texttt{Area of base = }6\times \frac{\sqrt{3}}{4}a^2=6\times \frac{\sqrt{3}}{4}\times 4^2=24\sqrt{3}unit^2[/tex]

The table shows the electric current produced by a solar cell in different amounts of sunlight (light intensity). Answer the questions using the data. I only need help on 5 and 6
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

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.
Triangle ABC has vertices A(5, 3) , B(3, 7) , and C(1, 4) . Triangle ABC is dilated, and the vertices of the image are A′(1.25, 0.75) , B′(0.75, 1.75) , and C′(0.25, 1) . The center of dilation is the origin.
What is the scale factor of the dilation?
A.) 0.25
B.) 0.5
C.) 2
D.) 4
Answers
To find the scale factor, we need to determine how the points are changing.
Point A is changing from (5, 3) to (1.25, 0.75). Therefore, we can write the following two equations using K as the scale factor.
5k = 1.25 or 3K = 0.75
Solving either equation will give you a scale factor of 0.25.
