Identify the amount (a) and the growth factor (b) in each exponential function. Break B into (1+r) where the rate of growth. Give r as a percentage.
y=1.07 (1.96)x
a
b=
r(as a percentage)
Answers
Answer:
a = 1.07
b = 1.96
r = 96%
Step-by-step explanation:
In an exponential function, modeled by f(x) = a(b)ˣ, a is the initial value and b is the growth factor. If we apply this formula to the given function y = 1.07(1.96)ˣ, we can see that the initial value, a, is 1.07, and the growth factor, b, is 1.96.
Now, to break down b, 1.96, into a rate, you simply set it equal to the problem’s given (1 + r) equation to find the rate.
1.96 = 1 + r
So r = .96
Now, we just have to convert .96 into a percentage to get a growth rate of 96%.

You are in charge of snacks for a youth event. You send your cousin Norm who is a complete nerd to
the store to price some items for you. For some inexplicable reason instead of telling you the price
for each item, he gives you this information:
If you buy 3 bags of Reese's Peanut Butter Cups and 6 bags of York Peppermint Patties, it costs $48.
If you buy 4 bags of Reese's Peanut Butter Cups and 3 bags of York Peppermint Patties, it costs $51.
Figure out how much each single bag costs. (Do not enter a $, just the number)
Reese's Peanut Butter Cups:
York Peppermint Patties:
Answers
Answer:
Reese's Peanut Butter Cups: 10.8
York Peppermint Patties: 2.6
Step-by-step explanation:
Let Reese's Peanut Butter Cups be r and York Peppermint Patties y.
Step 1: Make equations.
1) If you buy 3 bags of Reese's Peanut Butter Cups and 6 bags of York Peppermint Patties, it costs $48.
[tex]3r + 6y = 48[/tex]
2) If you buy 4 bags of Reese's Peanut Butter Cups and 3 bags of York Peppermint Patties, it costs $51.
[tex]4r + 3y = 51[/tex]
Step 2: Solve the system of equations.
We have system of equations. I'll solve them by elimination.
[tex](1.) \text{ } 3r + 6y = 48\\(2.) \text{ } 4r + 3y = 51[/tex]
Multiply the second equation with 2 so we'll get 6y.
[tex](1.) \text{ } 3r + 6y = 48\\(2.) \text{ } 8r + 6y = 102[/tex]
Now let's subtract second equation from first and solve for r.
[tex]3r - 8r + 6y - 6y = 48 - 102\\-5r = -54\\r = \frac{-54}{-5}\\r = \$10.8[/tex]
To get y let's substitute the value of r in first equation.
[tex]3r + 6y = 48\\3 \cdot 10.8 + 6y = 48\\32.4 + 6y = 48\\6y = 15.6\\y = \$2.6[/tex]

A class has 45 students. Each student has either 5 dollars or 2 dollars. Which Which situation results in the class having an average of 3 dollars per student
Answers
Step-by-step explanation:
an average of $3 per student would mean
sum(all students $) / 45 = 3
sum(all students $) = 3×45 = 135
x students have $5.
therefore (45-x) students have $2.
5x + 2(45-x) = 135
5x + 90 - 2x = 135
3x = 45
x = 15
so, 15 students have $5, and 45-15 = 30 students have $2.

Answer:
y = -5x + 4.
Step-by-step explanation:
y = mx + c is the general form
- where m = the slope of the line and c is the y-value where the graph cuts the y-axis.
The graph passes through the points (0, 4) and (1, -1) so the slope
= (Y2 - y1) / (x2 - x1)
= (-1-4) / (1-0)
= -5 = m.
and c = 4.

Let t be the number of tulips you buy and r be the number of rose bushes.
a.
The system is:
t + r = 13
4t + 10r = 100
b.
Solving:
4t + 10r = 100
t + r = 13 Multiply this by 4:
4t + 4r = 52 Subtract this from the first equation:
0 + 6r = 48
r = 8.
Now substitute for r in t + r = 13:
t + 8 = 13
t = 5.
c.
To buy 13 plants and spend $100 you need to buy 5 tulips and 6 rose bushes.
A grandsons age in years is equal to his grandfather's age in years. The difference of the grandsons age in years and the grandfather's age in years is 77. Find the grandsons age in years.

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let's suppose the age of the grandsons is x years and
age of the grandfather's age is y years
Here some data are misprinted, so we are assuming the grandson's age in months is equal to the age of grandpa in years and the difference in age is 77.
Then according to the problem:
12x = y (as in 1 year, there are 12 months)
y -x = 77 (as difference in age is 77)
After solving both equations, we get:
x = 7 years and y = 84 years
Thus, the age of the grandson is 7 years and the grandfather is 84 years if the grandson's age in months is equal to the age of grandpa in years and the difference in age is 77.

Answers
12 students are wearing sneakers.
Answer:
12
Step-by-step explanation:
So, the ratio is 3:4. That means this is for every 7 students. We have 28 students, so we need to know how many times 7 was multiplied to get to 28. 28 divided by 7 gives you 4. Now, we have to multiply both numbers in the ratio by 4. 3 times 4 is 12, and 4 times 4 is 16. The new ratio is 12:16. The students wearing sneakers were originally the 3 that got multiplied into 12, so the answer is 12.

Bajo la suposición de que las ciudades se hallan en la misma latitud, la distancia estimada entre las dos ciudades es de aproximadamente 6814 kilómetros.
Cómo se estima la distancia entre dos ciudades
En esta pregunta asumimos que la Tierra tiene una geometría esférica, de modo que los cálculos de arcos circulares se pueden obtener de manera simple y ágil. Por otra parte, también asumimos que las que la ciudad de Londres se encuentra a la misma latitud que la ciudad de Nueva York.
Es posible determinar la distancia estimada mediante la siguiente ecuación de arco circular:
s = [(θ' - θ) · π/180] · R · cos α (1)
Where:
θ' - Longitud de la ciudad de Londres, grados.θ - Longitud de la ciudad de Nueva York, en grados.α - Latitud de la ciudad de Nueva York, en grados.R - Radio ecuatorial de la Tierra, en kilómetros.Si sabemos que θ' = 7°, θ = - 73°, α = 40° y R = 6371 km, entonces la distancia estimada entre la ciudades de Nueva York y Londres es:
s = [(7+73)/180] · π · (6371 · cos 40°)
s ≈ 6814.420 km
