Find the radius and center of the circle given by the equation below.
(x-6)2 + (y + 4)2 = 7
Ore 17 and center at (-4.6)
or= 7 and center at (6-4)
or=7 and center at (-6.4)
or= 7 and (
6-4)
Answer:
center (6,-4)
radius = √7 unit
Step-by-step explanation:
Mathematically, the equation of a circle can be written as follows;
(x-a)^2 + (y-b)^2 = r^2
Where (a,b) represents the center of the circle with r representing the radius of the circle.
Now looking at the values in the question, we can clearly see that a = 6, while b represents -4.
The radius of the circle is √7
So the circle center is (6,-4) while √7 is the circle center
Jason is scuba diving at a constant rate toward the ocean floor. The equation
y= -2.5x – 5 can be used to represent this situation, where y is the depth of Jason in meters
below sea level and x is the number of seconds Jason has been swimming.
Which statement best describes the depth of Jason, given this equation?
Jason started scuba diving 2.5 meters below sea level and is ascending at a rate of 2.5 meters per
second.
Jason started scuba diving 5 meters below sea level and is ascending at a rate of 2.5
meters per second.
Jason started scuba diving 2.5 meters below sea level and is descending at a rate of 2.5
meters per second.
Jason started scuba diving 5 meters below sea level and is descending at a rate of 2.5
meters per second.
Answer:
Jason started scuba diving 5 meters below sea level and is descending at a rate of 2.5 meters per second.
Step-by-step explanation:
Jason is scuba diving at a constant rate toward the ocean floor.
Equation: [tex]y= -2.5x- 5[/tex]
x = The number of seconds Jason has been swimming.
y=The depth of Jason in meters below sea level
General equation : y=mx+c
m = Slope = rate of change per unit
On comparing m = -2.5
Negative signs represents the descending .
So, rate of descending per second = 2.5 m/sec
-5 denotes the initial position below sea level
So, Option D is true
So, Jason started scuba diving 5 meters below sea level and is descending at a rate of 2.5 meters per second.

Find the 7th term of the geometric progression which begins -6250, 1250, -250
Answer:
[tex]-\frac{2}{5}[/tex]
Step-by-step explanation:
The geometric progression given is:
-6250, 1250, -250...
The first term (a) is -6250, and the common ratio (r) can be gotten by dividing the second term by the first term:
r = 1250/-6250 = [tex]-\frac{1}{5}[/tex]
A geometric progression is generally given as:
[tex]a_n = ar^{n - 1}[/tex]
where [tex]a_n[/tex] = nth term
The 7th term of the progression above is therefore:
[tex]a_7 = -6250 * (-\frac{1}{5} )^6\\\\a_7 = -\frac{2}{5}[/tex]
The 7th term of the geometric progression is;
a_7 = -2/5
The formula for the nth term of a geometric progression is;
a_n = ar^(n - 1)
Where;
a is first term
r is common ratio
n is the position of the term in the series
We are given the series;
-6250, 1250, -250...
Thus;
First term; a = -6250
Common ratio; r = 1250/-6250
r = -1/5
Thus;
a_7 = -6250(-1/5)^(7 - 1)
a_7 = -2/5

Calculate the width of a 70" TV if the TV has an aspect ratio of 16:9.
Answer:
The TV has a length of 61.01" and a height of 34.32"
Step-by-step explanation:
The size of a TV is given by the length of it's diagonal, in this case the diagonal of the TV is 70". The ratio of the screen is 16:9, which means that for every 16 units on the length of the tv there are 9 inches on its height. The diagonal of the screen forms a right angle with the length and the width, therefore we can apply Pythagora's theorem as shown below:
[tex]diagonal^2 = height^2 + length^2\\\\height^2 + length^2 = (70)^2\\\\height^2 + length^2 = 4900[/tex]
Since the ratio is 16:9, we have:
[tex]9*length = 16*height[/tex]
[tex]length = \frac{16}{9}*height[/tex]
Applying this on the first equation, we have:
[tex]height^2 + (\frac{16}{9}*height)^2 = 4900\\\\height^2 + \frac{256}{81}*height^2 = 4900\\\\\frac{337}{81}*height^2 = 4900\\\\height^2 = \frac{4900*81}{337}\\\\height^2 = \frac{396900}{337}\\\\height^2 = 1177.744\\\\height = \sqrt{1177.744}\\\\height = 34.32[/tex]
[tex]length = \frac{16}{9}*34.32\\\\length = 61.01[/tex]
The TV has a length of 61.01" and a height of 34.32"

A 4-inch by 2-inch piece of granite that is 5 feet long is cut lengthwise along its diagonal. Find the perimeter and area of the cross section formed by the cut.
Answer:
Perimeter of the cross section = (10+4√5)inches = 18.9in
Area of the cross section= = 10√5 in²
Step-by-step explanation:
Find attached the diagrams used in solving the question
Dimensions of granite = 4in by 2in
Length = 4in
Breadth = 2in
Height = 5in
When granite is cut lengthwise along it's diagonal, the cross section formed by the cut will be a rectangle.
Perimeter of the cross section = 2(height+breadth)
Breadth = diagonal of the cross section
The diagonal of a rectangle divides the rectangle into two right angled triangles.
We would apply Pythagoras theorem to find the length of the diagonal
Hypotenuse ² = opposite ²+adjacent ²
Hypotenuse = length of diagonal
Hypotenuse ² = 2² + 4²
Hypotenuse ² = 4+16 = 20
Hypotenuse = √20 = 2√5
Perimeter of the cross section = 2(height+breadth) =2(5+2√5)
Perimeter of the rectangle = 10+4√5 inches = 18.9in
Area of the cross section= diagonal × height
Area of the cross section= 2√5 × 5
Area of the cross section= = 10√5 in²

Step-by-step explanation:
I can't type all of them 'cause it's much
Answer:
1. a. x= 18°
sum of interior angles is = 180°, so, to get x, = 2.5x + 4.5x + 3x = 180°
2.5x = 45
4.5x = 81
3x = 54
2. a. x = 75°
x - 10 = 65
x-35 = 40
x = 75
use the concept in number one.
3. a. x = 25
the two opposite interior angles add up to the exterior angle . so,
4x + 55 = x + 130
like terms together then simplify to get x as 25
so 4x = 100°
x + 130 = 155°
4. ∠2 = 180 - (38+34) = 108°
∠5 = 180 - (38+74) = 68°
∠6 = 74 + 38 = 112°

A water balloon is thrown from the top of a house. The path of the balloon is modelled by the relation, h = -4.9t2 – 14.7t + 19.6,
where h is the balloon's height, in meters, above ground, and wheret is the time, in seconds.
a.
How tall is the house? (1 mark)
b. How long does it take for the balloon to hit the ground? (3 marks)
What is the maximum height that the balloon reaches? marks)
C.
Answer:
(a)19.6 meters
(b) 1 seconds
(c)30.625 meters
Step-by-step explanation:
The height of the balloon is modeled by the equation:
[tex]h = -4.9t^2- 14.7t + 19.6[/tex]
(a)Since the balloon is thrown from the top of the house, the height of the house is at t=0
When t=0
[tex]h(0) = -4.9(0)^2- 14.7(0) + 19.6\\h=19.6$ meters[/tex]
The height of the house is 19.6 meters.
(b)When the balloon hits the ground
Its height, h(t)=0
Therefore, we solve h(t)=0 for values of t.
[tex]h = -4.9t^2- 14.7t + 19.6=0[/tex]
[tex]-49t^2-147t+196=0\\-49(t^2+3t-4)=0\\t^2+4t-t-4=0\\t(t+4)-1(t+4)=0\\(t+4)(t-1)=0\\t+4=0$ or $t-1=0\\t=-4$ or t=1[/tex]
Therefore, the ball hits the ground after 1 seconds.
(c)To determine the maximum height, we take the derivative of the function and solve it for its critical point.
[tex]If$ h = -4.9t^2- 14.7t + 19.6\\h'(t)=-9.8t-14.7\\$Setting the derivative equal to zero$\\-9.8t-14.7=0\\-9.8t=14.7\\t=-1.5\\$Therefore, the maximum height, h(t) is:\\h(1.5) = -4.9(-1.5)^2- 14.7(-1.5) + 19.6\\=30.625$ meters[/tex]

A hiker climbs a 5-mile trail up a mountain in 2 hours. On the return trip downhill, she walks the same trail and returns to her starting point in 1 hour. What was her average rate of speed, in miles per hour, for the entire trip?
Answer:
3.33 miles per hour
Step-by-step explanation:
The total distance traveled by the hiker is 5 * 2 = 10 miles, and the total time travelled is 2 + 1 = 3 hours.
So, to find the average speed of the entire trip, we can use the formula:
distance = speed * time
With distance = 10 and time = 3, we have:
10 = speed * 3
speed = 10/3 = 3.33 miles per hour.

If ladders are difficult to use for high floors, what are some other options? What is the level of safety of each of your options? Explain using mathematical facts.
Answer:
Stairs, escalators, elevators, ramps...
Step-by-step explanation:
If ladders are difficult to use for high floors another very common options are stairs. you see them pretty much everywhere. Escalators and elevators are also used, elevators more often that escalators.
I don't know how to make it sound "mathy" but..
Ladders are super straight and so for high floors, the slope of the ladder will be too steep for anyone to climb without gravity interfering.
The level of safety with stairs is higher because instead of going straight up, The steps provide a flat surface for someone to stand on while climbing the stairs and there is a much more stable foundation. Stairs can have protection like a guard rail and even go in a spiral motion upwards because they are more stable and safe. It is still possible to fall if one is not careful because of pesky gravity.
Escalators are pretty much moving stairs and the level of safety is greater because of the strong foundation and flat surface to stand on. Of course falling can happen, lowering the safety, but this is not likely because of the slowly enough moving steps. There is a rail as well and as long as people are careful, there aren't usually any casualties.
Elevators take up way less space than stairs and escalators because they can go straight up and down. The level of safety is fairly high because an elevator is a pulley system and people don't involve all that much moving around. Just go in the mechanical box, the doors close for safety, click a button, and then go up or down.
I don't know how to incorporate mathematical facts into this question because this is literally logic not math in my opinion. Honestly, ladders aren't even used that much, I don't think, except for building and house work.
I hope this helps you with whatever you are doing!

The gasoline mileage for two cars can be compared by finding the distance each car traveled and the amount of gasoline used. The table shows the distance that car M traveled using x gallons of gasoline.
The graph shows the distance, y, that car P traveled using x gallons of gasoline
Answer:
Car M:
50.4/2 = 25.2
car M uses up 1 gallon every 25.2 miles
Car P:
Just from the graph, you can see that it uses up 1 gallon every 30 miles
The two graphs vary the /miles slightly but it is around their zones of 25.2 and 30. It varies slightly because the cars may be traveling at a fast speed or slower speed thus using up more or less fuel by the time they've reached the recorded distances on the graphs.
1. In triangle ABC, if AB = 3cm, BC = 4cm and AC = 5cm Find
A. The area of triangle ABC
B. The length of shortest altitude
What is the length of its diagonal
Answer:
Step-by-step explanation:
A) The diagram of the triangle is shown in the attached photo
The lengths of the given triangle form a Pythagoras triple. This means that the square of the longest side equals the sum of the squares of the two shorter sides.
Area = 1/2 × base × height
Height = 3 cm
Base = 4 cm
Area = 1/2 × 3 × 4 = 6 cm²
B) The altitudes can be AB or BC. Therefore, the length of the shortest altitude is AB = 3 cm
The diagonal is the same as the hypotenuse which is also the longest side of the triangle. Thus,
Length of diagonal = 5 cm
