A tree in the Amazon rain forest grows an average of 2.3 cm per week. Write a sequence that represents the weekly height of the tree if it is 7 meters tall today. Write a recursive formula for the sequence and find the height of the tree after 6 weeks.
Answer:
Recursive formula
= an = a1 +(n - 1)d
Where
a1 = First term
n = nth term
d = common difference
The height of the tree after 6 weeks = 711.5 centimeters or 7.115 meters
Step-by-step explanation:
Recursive formula
= an = a1 +(n - 1)d
Where
a1 = First term
n = nth term
d = common difference
We are told that the tree is 7 meters tall today = a1
We convert to centimeters
1m = 100cm
7m =
Cross Multiply
= 7 × 100cm
= 700cm
And it grows at an average of 2.3cm per week = 2.3
Hence, an = a1 +(n - 1)d
We are to find the height of the tree after 6 weeks
a6 = 700 + (6 - 1) 2.3
a6 = 700 + (5)2.3
a6 = 700 + 11.5
a6 = 711.5cm.
We can convert to meters if we like
= 100 cm = 1 m
711.5 cm =
711.5cm/100
= 7.115m
The height of the tree after 6 weeks is 711.5 cm or 7.11 meters

A bus travels 0.8 mile east every 45 seconds. A second bus travels 0.55 mile west every 30 seconds. The buses start at the same location. Use two methods to determine how far apart the buses are after 15 minutes.
Answer:
32.5 miles
Step-by-step explanation:
Given that:
Eastbound bus :
0.8 miles every 45 seconds
Speed per second :
0.8 / 45 = 0.0177777 miles per second
Distance after 15 minutes
(15 * 60) * 0.0177777 = 16 miles
Westbound bus:
0.55 miles every 30 seconds
Speed per second :
0.55 / 30 = 0.0183333 miles per second
Distance after 15 minutes :
(15 * 60) * 0.0183333 = 16.5 miles
Distance apart :
16 miles + 16.5 miles = 32.5 miles
METHOD 2:
Distance covered after 15 minutes :
15 minutes = 15 * 60 = 900 seconds
Distance apart after 900 seconds :
[0.8 * (900/45)] + [0.55 * (900/30)]
16 + 16.5
= 32.5 miles

Janice went to 5 different stores in the mall. She spent an average of $30 at each store. After visiting just the first 4 stores she had spent $100. How much must she have spent
A.)525
B.)$30
С.)$50
D.)$70
We want to find how much Janice spends on her last purchase.
The correct option here is C, she must have spent $50 on the last store.
Let's see how to get the correct answer:
We know that the average is $30 per store, and we know that she goes to 5 stores, then the total amount spent in the 5 stores is:
5*$30 = $150
Notice that average is just given by the total amount of money she spent divided the number of stores she visited, this does not mean that she spent $30 in each of these stores.
Now, we also know that in the first 4 stores she spents a total of $100.
We want to know how much does she spend on the last store, this will be given by the difference between the total amount and $100, this is:
$150 - $100 = $50
So she must have spent $50 on the last store, meaning that the correct option is C.

ABC=40 and Bd is angle bisector of ABC what is ABD= ?
Answer:
20
Step-by-step explanation:
40 ÷ 2 = 20
its 20 since BD is an angle that bisects " divdes " angles in half.
The measure of angle ABD is 20 degrees and this can be determined by using the properties of the angle bisector.
Given :
ABC = 40 and BD is the angle bisector of angle ABC.
The following steps can be used in order to determine the angle ABD:
Step 1 - According to the given data, BD is the angle bisector of angle ABC.
Step 2 - An angle bisector bisects the angle into two equal parts.
Step 3 - So, the measure of angle ABD is calculated as:
[tex]\angle ABD = \dfrac{\angle ABC}{2}\\\\ \angle ABD = \dfrac{40}{2}\\\\ \angle ABD = 20^\circ[/tex]
So, the measure of angle ABD is 20 degrees.

A cat spends 2/3 of its life asleep. If a cat lives to be 15 years old, how many years di it spend asleep?
Answer:
10 years
Step-by-step explanation:
You start by writing an equation:
(2/3) * (15) = x
x being how many years it has been asleep.
Then multiply the two numbers together:
x = 10
Answer:
10 years
Step-by-step explanation:
Divide the cats life by the denominator to find how much it sleeps for 1/3 of its life.
15 3 = 5 years
Multiply 5 by the numerator to find how much it sleeps for 2/3 of its life.
5 * 2 = 10 years

A bathtub is draining at a constant rate. After 3 minutes, it holds 36 gallons of water. Seven minutes later, it holds 15 gallons of water. Write an equation the represents the number y of gallons in the tub after x minutes
Answer:
y = 45 - 3x
Step-by-step explanation:
Given that:
Bathtub drains at a constant rate :
Amount of water in tub after 3 minutes = 36 gallons
Amount of water in tub after 7 minutes later (3 + 7) ;(after 10 minutes) = 15 gallons
Using the slope - intercept relation:
y = mx + c
y = gallons in tub after x minutes
m = slope (rate at which water drains per minute)
C = intercept
Hence,
Amount of water in tub after 3 minutes = 36 gallons ; x = 3,; y = 36
Since water is draining gradient m is negative
36 = c - 3m - - - (1)
Amount of water in tub after 7 minutes later (3 + 7) ;(after 10 minutes) = 15 gallons
15 = c - 10m - - - (2)
Subtract (2) from (1)
21 = - 3m + 10m
21 = 7m
m = 3
From (1)
36 = c - 3(3)
36 = c - 9
36+ 9 = c
45 = c
Hence, the equation becomes ;
y = 45 - 3x

Which graph represents an even function?
On a coordinate plane, a hyperbola has a curve in quadrant 1 and a curve in quadrant 3. The curve in quadrant 1 has a vertex at (2, 2) and goes through points (1, 5) and (5, 1). The curve in quadrant 3 has a vertex at (negative 2, negative 2) and goes through points (negative 5, negative 1) and (negative 1, negative 5).
On a coordinate plane, a function has two curves. The first curve is asymptotic to x = negative 3, goes through (negative 2, 0), has a minimum of (negative 1.5, negative 1), goes through (negative 1, 0), and connects with the second curve at (0.5, 3). The second curve starts at (0.5, 3), goes through (2, 0), has a minimum of (2.5, negative 1), goes through (3, 0), and is asymptotic to x = 4.
On a coordinate plane, a parabola opens down. It goes through (negative 2, 0), has a vertex at (0, 4), and goes through (2, 0).
On a coordinate plane, a straight line has a negative slope. It goes through (negative 2, 4), crosses the y-axis at (0, 2), and crosses the x-axis at (2, 0).
Using the concept of even function, it is found that the graph that represents an even function is the third option, given by:
On a coordinate plane, a parabola opens down. It goes through (-2, 0), has a vertex at (0, 4), and goes through (2, 0).
--------------------------------
For an even function, [tex]\mathbf{f(x) = f(-x)}[/tex] for all values of x.--------------------------------
For the first option, [tex]f(1) = 5[/tex], and [tex]f(-1) = -5[/tex], thus [tex]\mathbf{f(x) \neq f(-x)}[/tex], and the function is not even.For the second option, there are asymptotes, thus, it is not even.For the third option, from the information given, [tex]\mathbf{f(-2) = f(2)} = 0[/tex], we suppose this extends for all values of x, thus, it is even, and this is the correct option.For the fourth option, [tex]f(-2) = 4[/tex] and [tex]f(2) = 0[/tex], thus [tex]\mathbf{f(-x) \neq f(x)}[/tex], and the function is not even.A similar problem is given at https://brainly.com/question/16711376

Answer:
9 rows
Step-by-step explanation:
Given that:
Li Na wants to plant 63 tomato plants and 81 rhubarb plants
However, Li Na was hoping with the mindset to plant the plants in rows;
where each row possesses the same number of tomato plants and rhubarb plants.
So;
Suppose we choose a given number, Let's say (9) to be the divisor for both the number of tomato plants and rhubarb plants;
Then
63/9 tomato plants = 7 tomato plants
81/9 rhubarb plants = 9 rhubarb plants
Therefore, the greatest number of rows Li Na can plant 7 tomato plants and 9 rhubarb plants = 9

The percent of the area of rectangle PQRS is shaded is 25%.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word per cent means per 100.
Given:
The shape is a rectangle and it is cut into half using diagonal.
again cut by another diagonal which 1/4 section.
Now again it is one more time cutted but this time make section of 1/8
As, there are two shaded section
=1/8+1/8
=2/8
=1/4
