Answer:
(i) we will be finding the acceleration here, in the first 20 seconds the velocity was 10
a = velocity/time
a = 10/20
a = 0.5 ms -2
(ii) difference in distance of the bus and bicycle will be given by formula of velocity
velocity of bicycle
10 * 80 = distance
800 metres
velocity of bus
for first 20 seconds( distance= velocity* time)
200 metres
from 20 seconds to 60 seconds, it will be for 40 seconds
then distance will be,
400 metres
final 20 seconds
200 metres
adding the distances of bus it will be 800 metres.
the difference in distance will be 0 metres.
this is wat i think
A sequence can be generated by using fn = 2f(n-1)+1, where f1 = 4 and n is a whole number greater than 1. What are the first four terms in the sequence?
Answer:
{9,19,39,79}
Step-by-step explanation:
Recursive Sequences
The recursive sequence can be identified because each term is given as a function of one or more of the previous terms. Being n an integer greater than 1, then:
f(n) = 2f(n-1)+1
f(1) = 4
To find the first four terms of the sequence, we set n to the values {2,3,4,5}
For n=2f(2) = 2f(1)+1
Since f(1)=4:
f(2) = 2*4+1
f(2) = 9
For n=3f(3) = 2f(2)+1
Since f(2)=9:
f(3) = 2*9+1
f(3) = 19
For n=4f(4) = 2f(3)+1
Since f(3)=19:
f(4) = 2*19+1
f(4) = 39
For n=5f(5) = 2f(4)+1
Since f(4)=39:
f(5) = 2*39+1
f(5) = 79
what is x ?
what is y ?
Answer:
y = 100° , x = 80°
Step-by-step explanation:
Two angles on a straight line equal 180°. Therefore, 80° + y = 180°. This means y = 100°.
80° and x are alternate exterior angles. Using that property, we know those angles are congruent. This means x is also 80°.

A).1+ 4x+2/2x=5x
b).2x-2+3x/4=2x
A.
Divide the numbers
1 + 4x 2/2 • x =5x
1 + 4x + 1x =5x
Multiply by 1
1 + 4x + 1x=5x
Combine like terms
1 + 4x + x =5x
1 + 5x =5x
Subtract 1 from both sides of the equation
5x + 1 = 5x
5x + 1 - 1 =5x -1
Simplify
Subtract the numbers
5x = 5x -1
Subtract 5x from both sides of the equation
5x = 5x -1
5x - 5x = 5x -1 -5x
Simplify
0= -1
Result
0= -1

An average swimming pool contains 19200 gallons of water. The pool needs drained at the end of the summer. Water drains from the pool at the rate of 12 gallons per
Which equation can be used to find the volume, V, of the water in the pool t minutes after draining begins?
A- V = 12t - 19200
B- V= 19200- 12/60t
C- V= 12/60t- 19200
D= V= 19200- 12t
PLEASE HELP ASAP
PLEASE EXPLAIN HOW YOU GOT THE ANSWER
Answer:
The answer is
D. V= 19200- 12t
Step-by-step explanation:
in this problem, we already know that the pool contains 19200 gallons of water
and the pool is draining at 12 gallons per minutes, hence the volume is decreasing at that rate
Therefore for t minutes it will decrease by 12t
hence the volume after t minutes will be
V= 19200-12t

Which description could be written as a linear function?
a) eight more than twice a number
b) three more than the product of two numbers
c) ten more than the square of a number
d) nine more than one divided by a number
Question:
Which description could be written as a linear function?
Answer:
Option a)
Explanation:
Let 2 numbers be x1 and x2.
For the first option:
Eight more than twice a number.
The graph would be y = 8 + 2x1 which is a linear function.
For the second option:
Three more than the product of two numbers.
The graph would be y = 3 + x1x2 which is a graph function.
For the third option:
Ten more than the square of a number.
The graph would be y = 9 + (x1)² which is a graph function.
For the fourth option:
Nine more than one divided by a number.
The graph would be y = 9 + 1/x1 which is a double-parabole function.
Hopefully this answer will help you.

Solve the equation using the Properties of Equality.
3- m/6= 12 solve for m
Answer:
[tex]m=-54[/tex]
Step-by-step explanation:
We have the equation [tex]3-\frac{m}{6}=12[/tex] and we want to solve for m using the Properties of Equality.
Steps:
1) Subtraction Property of Equality (subtract 3 from both sides):
[tex](3-\frac{m}{6})-3=(12)-3[/tex]
[tex]-\frac{m}{6}=9[/tex]
2) Multiplication Property of Equality (multiply both sides by -6):
[tex]-6(\frac{m}{-6})=-6(9)[/tex]
[tex]m=-54[/tex]
Therefore, our final answer is [tex]m=-54[/tex]
An item has a listed price $95. if the sales tax rate is 7%, how much is the sales tax?
Answer:
$6.65
Step-by-step explanation:
Total sales tax = Item cost [tex]*[/tex] sales tax rate
Item Price: $95
Sales tax rate: 7% = 0.07
[tex]95*0.07=6.65[/tex]
Total sales tax = $6.65

For Geometry, thank you!
Answer:
Step-by-step explanation:
AB // CD and E F is transversal
∠ E FA = ∠F ED {alternate interior angles}
∠E FA = x
In Δ AG F,
∠G FA + ∠F AG +∠AG F = 180 {angle sum property of triangle}
x + 2 x + 3 x = 180 {Combine like terms}
6 x = 180 {divide both sides by 6}
x = 180/6
x = 30

A rectangles width is 13 more than its length. If the perimeter is 82 feet what is the length and width.
Answer:
Step-by-step explanation:
Lenght should be the greater here. I am considering your question however.
Let length side is 'x'.
The width side is 'x +13'
Perimeter of a rectangle : 2 ×( length + width)
given that perimeter is 82
2 × ( x + x + 13) = 82
2 × ( 2x + 13) =82
4x + 26 = 82
2x = 56
x = 28 cm
length is 28
width is 41

Question is in the image
Finding slope:
Take two pairs of cordinate points from the table and use the formula y2-y1 divided by x2-x1
I choose (4,3) and (2,2)
2-3 divided by 2-4
= -1/2
Then to get the y intercept you use the formula: y=mx+b
For the x and y pick a cordinate to plug in. For m plug in your slope.
I pick (6,4)
4=-1/2×6+b
Multiply -1/2 and 6 to get -3 and plug that in
4=-3+b
Now add 3 to the -3 canceling that out to 0 and add three to the 4 making that 7
7=b
Y-intercept =7
Now plug in the slope and y-intercept into the slope intercept format and get:
Y=-1/2x+7
