What is the distance between y = 3x + 9 and y = 3x - 4?
Answer:
A. 4.11 units
Step-by-step explanation:
It can be convenient to put one of these equations into general form, then use the formula for the distance from a point to a line.
In general form, the first equation is ...
3x -y +9 = 0
So, the distance from a point to that line is ...
ax +by +c = 0 . . . . . . equation of a line
d = |ax +by +c|/√(a^2+b^2) . . . corresponding distance formula
d = |3x -y +9|/√(3^2 +(-1)^2)
Using the y-intercept of the other line as the point of interest, we find its distance to the first line to be ...
d = |3(0) -(-4)+9|/√10 = 13/√10 ≈ 4.11
The distance between the lines is about 4.11 units.
_____
Unless the lines are vertical or horizontal, you know the distance will be less than the difference between the x- or y- intercepts. Here, the y-intercepts are separated by 9-(-4) = 13 units. The x-intercepts are -3 and 4/3, so are separated by 4 1/3 units. Any answer choice larger than 4.33 cannot be correct.

Suppose that a spotlight is used for lighting objects at many different distances and that the area A of the light circle produced is related to the distance x to the lighted object by A=0.1x^2.
a. If the spotlight produces 250 lumens of light energy, what function gives the intensity of the light I, (in lumens per square foot) as a function of the distance x in feet from the spotlight to its target?
b. Write and solve equations that match these questions about the light intensity from the spotlight.
i. What is the intensity of light on an object that is 20 feet from the spotlight source?
ii. How far from the spotlight is an object that recieves 100 lumens of light per square foot?
Answer:
Intensity = 2500/x^2
6.25 lumem
5 Feets
Step-by-step explanation:
Given the following :
Area (A) = 0.1x^2
Intensity, Energy and Area are related by the formular :
Intensity = power / Area
A) If 250 lumens of light energy is produced :
Intensity (I) = 250 / 0.1x^2
Intensity = 2500/x^2
x = distance
B) USING THE EQUATION :
1) What is the intensity of light on an object that is 20 feet from the spotlight source?
x = 20
Intensity = 2500/x^2
Intensity = 2500/20^2
Intensity = 2500/400
Intensity = 6.25 lumen
11) How far from the spotlight is an object that recieves 100 lumens of light per square foot?
Intensity = 100
100 = 2500 / x^2
100x^2 = 2500
x^2 = 2500/ 100
x^2 = 25
x = 5 Feets

Question 13
A train runs 68m, 127m, 208m, 312m, and 535m in five successive minutes after it
starts. For the next five minutes, it runs an average speed of 33 km/h. Find the
total distance covered in ten minutes,
A. 12 km
B. 10 km
C. 4 km
D. none
Answer:
C
Step-by-step explanation:
Here in this question , we are interested in calculating the total distance covered by the train in the 10 minutes that it ran.
From the first part of the question, we already know the distances in the first 5 minutes.
Now, to calculate the total distance in the second 5 minutes, we use the distance formula since we have the average speed and the time;
Mathematically; Total distance = average speed * time
From the question, average speed is 33km/h, while time is 5 minutes. To achieve a consistent unit, we convert 5 minutes to hours.
That would be 5/60 = 1/12 hours
So the total distance in the second 5 minutes is;
33 * 1/12 = 2.75 km
Now, to calculate the total distance traveled, let’s add up the distances in the first 5 minutes and convert to kilometers;
That would be;
68 + 127 + 208 + 312 + 535 = 1,250 m
Let’s convert this to km.
We simply divide by 1000 = 1250/1000 = 1.25 km
The total distance is thus ;
1.25 + 2.75 = 4 km

[tex]:\implies\sf\:f(x)=3x+10[/tex]
[tex]:\implies\sf\:f(g(5))=3x+10[/tex]
[tex]:\implies\sf\:f(3)=3(3)+10[/tex]

A box is filled with 2 yellow cards, 4 blue cards, and 12 red cards. A card is chosen at random from the box. What is the probability that the card is not blue? Write your answer as a fraction in simplest form.
Answer:
7/9
Step-by-step explanation:
Given:
Number of yellow cards=2
Number of red cards=12
Number of blue cards=4
Total number of cards= Number of yellow cards+Number of red cards+Number of blue cards
= 2+4+12=18cards
Probability of a NON-blue card = number of non blue/ total number
where NON-blue= Number of red cards+
Number of yellow cards
= 2+12=14
P(not blue)=
=14/18
7/9
Therefore, probability that the card is not blue is 7/9

8+35/w=15
a.8
b.6
c.10
d.5
Answer:
[tex] \boxed{ \bold{ \huge{ \bold{w = 5}}}}[/tex]
Option D is the correct option
Step-by-step explanation:
[tex] \sf{8 + \frac{35}{w} = 15}[/tex]
⇒[tex] \sf{ \frac{8 \times w + 35}{w} = 15}[/tex] { w ÷ 1 = w , So, I wrote 8 × w }
⇒[tex] \sf{ \frac{8w + 35}{w} = 15}[/tex]
Apply cross product property
⇒[tex] \sf{8w + 35 = 15w}[/tex]
Move 15w to left hand side and change it's sign
Similarly, Move 35 to right hand side and change it's sign
⇒[tex] \sf{8w - 15w = - 35}[/tex]
Collect like terms
⇒[tex] \sf{ - 7 w = - 35 }[/tex]
Divide both sides of the equation by -7
⇒[tex] \sf{ \frac{ - 7w}{ - 7} = \frac{ - 35}{ - 7} }[/tex]
Calculate
⇒[tex] \sf{w = 5}[/tex]
Hope I helped!
Best regards!!
Answer:
w = 5
Step-by-step explanation:
8 + [tex]\frac{35}{w}[/tex] = 15
subtract 8 from both sides
8 + [tex]\frac{35}{w}[/tex] - 8 = 15 - 8
simplify
[tex]\frac{35}{w}[/tex] = 7
35/7 = w
w = 5
Find the measure of b+d. A. 74 B. 90 C. 32 D. 58
Answer:
B. 90°
Step-by-step explanation:
Quadrilateral inscribed in the circle with center O is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
(b + d) + (32° + 58°) = 180°
b + d + 90° = 180°
b + d = 180° - 90°
b + d = 90°
Why is it important that the term “locked” is used when making the following statement? You can use a locked compass setting and a straightedge to draw two congruent segments.
You use a compass to draw an arc (or a full circle). The radius must be kept the same so that you can copy the length of the segment properly. If the compass could move freely, then it is unlikely the arc will be a piece of a circle, and rather some squiggly curve. So this is why the compass width must be locked into place.

In Ms. Ford's classroom 13 students are able to fit comfortably into a 5 by 5 square.
Use this value to estimate the size of a crowd that is 10 feet deep on both sides of the street standing
along a 1-mile section of a parade route.
Answer:
Estimate of crowd is 27456.
Step-by-step explanation:
Given that a square of 5 by 5 can have 13 students.
Area of a square = [tex]side^2[/tex] = 25
Area of 25 can have 13 students.
Now, it is given that 10 feet square are used for crowd.
Area of square of side 10 feet = 100
So, area of 100 can have 13 [tex]\times[/tex] 4 = 52 people from crowd
Now, it is given that the parade route is 1 mile long.
1 mile = 5280 feet
1 mile = 528 [tex]\times[/tex] 10 feet
It means that there are 528 number of such squares on the 1 mile section of the parade route.
Kindly refer to the attached image as well.
So, number of people or the estimate of the size of crowd is:
528 [tex]\times[/tex] 52 = 27456

Suppose the population of a town is 8,200 and is growing 4% each year, what is the population expected to be in 10 years
Answer:
12,138 people
Step-by-step explanation:
Create an equation using the basic exponential growth equation:
y = a(1 + r)^t, where a is the initial amount, r is the growth rate as a decimal, and t is the amount of time in years.
Plug in the values we know
y = a(1 + r)^t
y = 8200(1 + 0.04)^10
y = 8200(1.04)^10
= 12,138 people
