Describe the end behavior of the given function f(x)=2/3x-2
Answer:
The end behavior of f(x)=2/3x-2 is: as x->+ infinity, f(x)->+ infinity
as x->- infinity, f(x)->- infinity
Step-by-step explanation:
When you are asked about the end behavior of a function, look to see where the function is traveling on the graph. For instance, this graph is linear, so you should look to see if the slope is positive or negative. This linear function is positive, so as x is reaching positive infinity the f(x) would also be reaching positive infinity. As x is reaching negative infinity, f(x) would also be reaching negative infinity. The end behavior of a function describes the trend of the graph on the left and right side of the x- axis. (As x approaches negative infinity and as x approaches positive infinity).

Step-by-step explanation:
We substitute a for 1 and b for 6.
5(1+6)=5(7)=35
The sketch shows part of the graph y=ab^x
Answer:
a = 3, b = 2
[tex]y = 3\cdot 2^x[/tex]
Step-by-step explanation:
[tex]y = ab^x\\3 = ab^0\\12 = ab^2\\~\\3=ab^0=a\cdot 1 = a\\a = 3\\~\\12 = ab^2 = 3b^2\\4 = b^2\\b = 2 \vee b = -2[/tex]
but we know from the graph being defined and positive, that b cannot be -2
b = 2
The value of a is 3 and value of b is 2.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The graph is y=abˣ
The points with coordinates (0, 3) and (2, 12) lie on the graph.
We need to find the values of a and b.
The point (0, 3)
3=ab⁰
a=3
Now point (2, 12)
12=ab²
Now plug in a value as 3
12=3b²
Divide both sides by 3
12/3=b²
4=b²
b=2
Hence, the value of a is 3 and value of b is 2.

Step-by-step explanation:
Long until a new elementary school needed is 9.6.
How to estimate compound interest?Given:
Interest rate, r = 6.2% or 0.062
Amount, A = 100000
Principle, P = 76000
As we know,
[tex]$\Rightarrow A=P\left(1+\frac{r}{100}\right)^{n}$$[/tex]
On substituting the values, we get
[tex]$&\Rightarrow 100000=76000\left(1+\frac{6.2}{100}\right)^{n} \\[/tex]
[tex]$&\Rightarrow(1+0.062)^{n}=\frac{100}{76}[/tex]
On taking log both sides, we get
[tex]$&\Rightarrow n \log _{c}(1.062)=\log _{c}\left(\frac{100}{76}\right) \\[/tex]
[tex]$&\Rightarrow \quad n=\frac{\ln \left(\frac{100}{76}\right)}{\ln (1.062)}[/tex]
By putting the values of log, we get
[tex]$\Rightarrow \quad=4.5622$[/tex]
[tex]$\Rightarrow \quad=4.6[/tex]
Therefore, the correct answer is 4.6.

Help a formula word problem. Thank you if you help. You're a genuis!
==========================================================
Explanation:
We start with one block at the very left side. This is algebraically written as [tex]a_1 = 1[/tex]. The small subscript '1' means we're dealing with the first term, and that is set equal to 1. In other words, the first term is 1.
The second term is three since we have three blocks as the next figure down the line. So [tex]a_2 = 3[/tex]. We can then see that [tex]a_3 = 6[/tex] and [tex]a_4 = 10[/tex]
The sequence of the first four terms are: 1, 3, 6, 10.
The notation [tex]a_n = a_{n-1} + n[/tex] tells us "to get the nth term [tex]a_n[/tex], we add the previous term ([tex]a_{n-1}[/tex]) to the value of n".
For example, if we wanted the third term, we would add the second term a2 onto the value of n = 2. In order to know a2, we need the diagram or you would have to use the recursive formula to find it.
Furthermore, it means that to find the fifth term [tex]a_5[/tex], we do the following
[tex]a_n = a_{n-1} + n\\\\a_5 = a_{5-1} + 5\\\\a_5 = a_{4} + 5\\\\a_5 = 10+5\\\\a_5 = 15[/tex]
The fifth figure will have 15 small little blocks to it. You can draw this out by copying the fourth figure, and then adding 5 smaller blocks to the very bottom portion. The sixth figure is basically a copy of the fifth one, but we have six little blocks along the bottom. This is the "plus n" being applied in the recursive formula.
So the 6th figure will have 15+6 = 21 blocks in total while the 7th figure has 21+7 = 28 blocks. This points us to choice (3).
Side note: These are known as triangular numbers. Note how the gaps between consecutive values of 1,3,6,10,15,21,28 is +2,+3,+4,+5,+6,+7.

A bag contains eight black cards numbered 1 through 8 and six red cards numbered 1 through 6. You choose a card at random what's the possible outcome
Answer:
14 possible outcomes
Step-by-step explanation:
It is given that :
There are 8 black cards numbered 1 through 8.
Therefore, Black 1, Black 2, Black 3, Black 4, Black 5, Black 6, Black 7, Black 8.
And there are 6 red cards numbered 1 through 6.
Therefore, Red 1, Red 2, Red 3, Red 4, Red 5, Red 6.
So the total number of cards is 8 + 6 = 14 cards.
So, there will be 14 possible outcomes if we choose a card randomly.

MODELING WITH SYSTEMS OF INEQUALITIES
There are many situations that arise in business and engineering that necessitate systems of linear inequalities. The region in the xy-plane that solves the systems often represents all of the viable solutions to the system, so being able to visualize this region can be extremely helpful. As always, with modeling, it is important to really read the problems and understand the physical quantities involved.
(a) If John works 14 hours mowing and 30 hours at the bakery, does this satisfy all of the problem’s constraints?
(b) If x represents the hours John spends mowing and y represents the hours he spends at the bakery, write a system of inequalities that describes this scenario.
The question is incomplete. The complete question is :
John mows yards for his father's landscaping business for $ 10 per hour and also at a bakery for $ 15 per hour. He can work at most 52 hours per weak during the summer. He needs to make at least $ 600 per week to cover his living expenses.
a) If John works 14 hours mowing and 30 hours at the bakery, does this satisfy all of the problem’s constraints?
(b) If x represents the hours John spends mowing and y represents the hours he spends at the bakery, write a system of inequalities that describes this scenario.
Answer:
a). No
b). 10x + 15y ≥ 600
Step-by-step explanation:
a). Number of hours John works mowing = 14 hours
Number of hours John works at bakery = 30 hours
Therefore, according tot he question,
= 14($10) + 30($15)
= 140 + 450
= $ 590
This is not enough money. He needs to earn $ 600 per week.
b). Given :
x = hours John spends mowing
y = hours John spends at the bakery
Therefore, the inequalities which describes this situation is:
x + y ≤ 52
10x + 15y ≥ 600

In Exercises 2 and 3, find the value of x that makes PQR ~JKL.
Answer:
2. 4

Step-by-step explanation:
2. 4 ~ 8
3 ~ x + 2
x + 1 ~ 10
8 / 4 = 2
2 (3) = x + 2
6 = x + 2
- 2 - 2
x = 4
2 (x + 1) = 10
/ 2 / 2
x + 1 = 5
- 1 - 1
x = 4
3. 9 ~ 13.5
x + 1 ~ 15
13.5 / 9 = 1.5
1.5 (x + 1) = 15
/ 1.5 / 1.5
x + 1 = 10

Answer:
$ 2320.3
Step-by-step explanation:
Leon has $77,343 in a savings account that earns 9% annually.The interestis not compounded.To the nearest cent,how much interest will he earnin 4 months?
Since the interest is not Compounded
We solve using Simple Interest formula
= P × R × T
P = $77,343
R = 9 %
T = 4 months
Converting to years
= 4/12 = 0.3333333333
Interest = $77,343 × 9% × 0.3333333333
=$2320.29
Approximately to the nearest cents = $2320.3

area of shaded portion of figure = 76.24 cm²
Step-by-step explanation:
find the area of the circle, a 60° segment of the circle, and an equilateral triangle with sides of 5 cm:
area of circle = πr² = (3.14)(5²) = 78.5 cm²
area of 60° segment of circle = 78.5/6 = 13.08 cm²
area of triangle = 1/2(4.33)(5) = 10.82 cm²
The shaded area will be:
full circle area - (60° segment - triangle) = 78.5 - 13.08 + 10.82 = 76.24 cm²
