Answer:
Rate of change is slope
To calculate slope its
y2 - y1 / x2- x1 = slope
Just choose 2 random sets from the table.
I’m gonna go with (0,-10) and (2,20)
Now calculate slope
20 - (-10) / 2 - 0
Solve.
30 / 2
30/2 = 15
Rate of change is 15

Find slope and y intercept
Answer:
slope is 1/4； y intercept is -2
Step-by-step explanation:
read your textbook carefully
you note that you are given two point the x-intercept and y-intercept:
(8,0) and (0,-2) respectively.
before doing exercise, you need to know what is the slope formula (read your book).
slope formula is the change in y over the change in x.
or you can perceive that slope mean when x move forward one unit, what is change in y( how many units the y move).

What is the value of b?
Answer:
b = 26
Step-by-step explanation:
As angles I and K are equal in the triangle, the sides opposing them should also be of the same length. Therefore, the value of b is equal to the side of the other side's measure, which is equal to 26.

Consider a circle. The length of the arc for the central angle of 45 degrees is 16cm, then the total circumference (perimeter) of the circle is
a) 126cm
b) 128cm
c) 162cm
d) 182cm
Answer:
b
Step-by-step explanation:
the arc length is calculated as
arc = circumference (C) × fraction of circle , then
16 = C × [tex]\frac{45}{360}[/tex] = C × [tex]\frac{1}{8}[/tex] ( multiply both sides by 8 )
128 = C
circumference of circle is 128 cm

Mr. Tan's rectangular swimming pool has an area of (81x2 - 144y2) square feet. What are the dimensions of his pool?
Answer:
The pool dimensions are thus (9x - 12y)(9x + 12y)
Step-by-step explanation:
(81x^2 - 144y^2) is the difference of two squares. Note that you must indicate exponentiation with " ^ ."
Factoring the difference of two squares: a^2 - b^2 = (a - b)(a + b)
Thus, (81x^2 - 144y^2) =
The pool dimensions are thus (9x - 12y)(9x + 12y)
Area of rectangle is Length times of Breadth. The pool dimensions are (9x - 12y) and (9x + 12y) when area of rectangular swimming pool is (81x2 - 144y2)
area of Mr. Tan's rectangular swimming pool is (81x^2 - 144y^2), we need to find the area of rectangle.
What is area of rectangle?Area of rectangle= Length*Breadth
The given area of Mr. Tan's rectangular swimming pool is (81x^2 - 144y^2),
(81x^2 - 144y^2)=Length * Breadth
We know that (a+b)(a-b)=a^2-b^2
So,
The factors of (9x^2-12y^2) is (9x+12y) and (9x-12y)
(9x^2-12y^2)=(9x+12y)(9x-12y)
=Length * Breadth
where length and breadth are two dimensions of rectangle
Therefore (9x+12y) and (9x-12y) are two dimensions of rectangle.

Pamela is 6 years younger than Jiri. The sum of their ages is 64. What is Jiro's age?
Let's use j to represent Jiri's age.
If Pamela is 6 years younger that Jiri, her age can be represented by j - 6.
Since the sum of their ages is 64, we can setup the equation j + (j - 6) = 64.
Simplifying on the left, we have 2j - 6 = 64.
Adding 6 to both sides, we have 2j = 70.
Dividing both sides by 2, we have j = 35.
So Jiri is 35 years old and Pamela is 6 years younger or 29 years old.

Select all the true statements (select 2)
If 16 adults go to the zoo, then 9 students can go.
If 8 more adults go to the zoo, that means there will be room for 12 fewer students.
If no adult chaperones were needed, 30 students could go to the zoo.
If ten students go to the zoo, then 15 adults can go.
Answer:
if no adult ones went, 30 students could go.
Step-by-step explanation:
If the cost of the student was 8, and there were 30 students going theoretically, this would be the most logical answer, since 8 multiplied by 30 is exactly 240
please help me guys
Step-by-step explanation:
midpoint : it is the point in the middle marking half of the total distance.
therefore,
1)
EV = LE = LV/2
10 = 5m
m = 2
2)
LR = RO = LO/2
n + 4 = 12
n = 8
3)
LER and LVO are similar triangles. that means they have the same angles, and the ratio of one corresponding pair of lines or sides between both triangles is the same for all corresponding line pairs.
we know e.g. LE/LV = 1/2.
the same ratio applies then to ER/VO = 1/2 = 18/20p.
18/20p = 1/2
18 = 20p/2
2×18 = 20p
36 = 20p
p = 36/20 = 9/5 = 1.88888888888...
4)
VL = 2×EL = 2×10 = 20
5)
LO = 2×RO = 2×12 = 24
6)
as we have already calculated for 3) :
VO = 36
7)
36 + 20 + 24 = 80
8)
10 + 12 + 18 = 40
9)
remember, the and angles in similar triangles.
LVO = 52°
10)
all angles around a single point in one side of a line are together 180°.
in this case there are 2 angles around E : LER and VER.
VER = 180 - LER = 180 - 52 = 128°

If a snail moves 1 1/2 feet in 3 3/4 hours, what is its speed in feet per hour? Show you
simplify your answer.
Answer:
2/5 feet an hour
Step-by-step explanation:
d=vt
1 1/2 or (3/2)=v(3.75hours or 15/4)
divide both sides by 3.75hours
0.4f/h=velocity/speed
or in fractions 2/5
The speed of the snail in feet per hour will be 0.40 feet per hour.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
If a snail moves 1 1/2 feet in 3 3/4 hours.
Convert the mixed fraction number into a decimal number. Then we have
1 1/2 feet = 1 + 0.5 = 1.5 feet
3 3/4 hours = 3 + 0.75 = 3.75 hours
Then the speed of the snail in feet per hour will be given as,
S = 1.50 / 3.75
S = 0.40 feet per hour
The speed of the snail in feet per hour will be 0.40 feet per hour.
More about the speed link is given below.
