Step-by-step explanation:
There are 2 1/3 inches in 1 2/5 groups of 1 2/3 inches.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
There are 1 2/5 groups of 1 2/3 inches.
Now,
Since, There are 1 2/5 groups of 1 2/3 inches.
Hence, The number of inches = 1 2/5 × 1 2/3
= 7/5 × 5/3
= 7/3 inches.
Thus, There are 2 1/3 inches in 1 2/5 groups of 1 2/3 inches.

let f(x)=4^x. The new function g(x)=f(x-1)+3 represents transformations that were made to function f. Type the new equation for g. g(x)=___
Describe the two types of transformations that occur between function f and function g. (use words like up, down, left, right, compression or stretch in your answer.)
Answer:
g(x) = [tex]4^{(x-1)}+3[/tex]
Step-by-step explanation:
Given exponential function is,
f(x) = [tex]4^{x}[/tex]
If the given function is shifted 1 unit to the right,
h(x) = f(x - 1)
= [tex]4^{(x-1)}[/tex]
If the function 'h' is shifted 3 units up,
g(x) = h(x) + 3
= [tex]4^{(x-1)}+3[/tex]
Therefore, transformed function will be,
g(x) = [tex]4^{(x-1)}+3[/tex]

The weight, y, in pounds, of puppies was tracked for the first 10 weeks after birth where t represents the number of weeks after birth. The linear model representing this relationship is ŷ = 2.3 + 5.73t. Collin wanted to predict the weight of a puppy at 14 weeks.
What is this an example of, and is this method a best practice for prediction? Explain your reasoning.
Answer:
This is an example of linear modeling. Linear modeling is a best practice for prediction as the prediction is accurate even though 14 weeks is outside the given interval of 10 weeks.
Step-by-step explanation:
thats just what it is
The solution is Option C )
This is an example of linear modeling. Linear modeling is a best practice for prediction as the prediction is accurate even though 14 weeks is outside the given interval of 10 weeks
What is Linear model?
A linear model is a model in which the terms are added, such as has been used so far in this section, rather than multiplied, divided, or given as a non-algebraic function. Linear modeling can predict the behavior of complex systems or analyze experimental, financial, and biological data.
Linear regression is a statistical method used to create a linear model. The model describes the relationship between a dependent variable y (also called the response) as a function of one or more independent variables Xi (called the predictors).
Given data ,
Weight of the puppies = y pounds
Number of weeks after birth = t
Linear model representing the relationship between weight of puppies and time after birth in weeks is y = 2.3 + 5.73t
This is a clear idea of Linear models because the data describe a continuous response variable as a function of one or more predictor variables.
Hence , this is an example of linear modeling. Linear modeling is a best practice for prediction as the prediction is accurate even though 14 weeks is outside the given interval of 10 weeks

Write the decimal as a fraction or mixed number in simplest form.
9.75
✨Answer:✨
9 3/4 (simplest form)
✨Step-by-step explanation:✨
1. Convert decimal into fraction:
9.75 = 975/100
2. Simplify:
975/100 = 39/4 = 9 3/4
A. Reduce fraction to lowest terms (25 is the greatest common divisor of 975 and 100. Reduce by dividing both numerator and denominator by 25):
975/100 = 975 ÷ 25 = 39/4
100 ÷ 25
B. Convert improper fraction to mixed number:
39/4 = 9 3/4
(39 ÷ 4 = 9 remainder 3)

What is an equation of the line that passes through the points (1,8) and (-1, -2)?
Put your answer in fully reduced form.
Answer:
y=5x+3
Step-by-step explanation:
First, we need to find the slope. Remember that the slope equation is [tex]m=\frac{y2-y1}{x2-x1}[/tex].
If we plug in the given points we get m=5. (let me know if you need further elaboration on this step)
So now that we have a slope, we can plug it into the slope-intercept equation.
y=mx+b
y=5x+b
We still need to find b (y-intercept), but luckily, we were given two points that we could plug in. I'm going to use (1,8) here.
8=5(1)+b
8=5+b
b=3
Now we have all of our parts and can put them into the equation.
y=5x+3
Hope this helped!

Answer:
+$90;
$1,600
Step-by-step explanation:
The equation, [tex] y = 1600 + 90x [/tex], given to us tells us much about the situation described above.
y = total pay
x = number of copies of Math is fun
1600 = y-intercept, that is the starting value or the pay he gets only if Sam sold 0 copy of Math is fun. That is, when x = 0, y = 1,600.
90 = unit rate or the change in the total pay for each copy of Math is fun that Sam sells.
Therefore, our answers would be:
+$90, and $1,600
Mary bought a shirt on sale for $15.00. The sales tax was 10%. If Mary paid with a $20 bill, what was her change?
A-$4.90
B-$5.00
C-$3.50
D-$1.50
Answer:
Her change was: $3.5
Step-by-step explanation:
Mary bought a shirt on sale for $15.00.
As the sales tax was 10%.
i.e. 10/100 × 15 = $1.5
so the sales tax on $15.00 was $1.5.
Hence, the total cost Mary had to pay to buy the shirt was:
$1.5 + $1.5 = $16.5
As Mary paid with a $20 bill, therefore the change can be calculated as
20 - 16.5 = $3.5.
Therefore, her change was: $3.5

A))5
B))6
C))7
D))8
E))9
Answer:
A altura máxima é 5
Step-by-step explanation:
Matematicamente, a altura máxima pode ser obtida
A altura máxima é simplesmente o vértice da parábola
Começamos diferenciando a função Isso será -8x
Agora, defina -8x como 0
Isso significa que x = 0
Agora, substitua x = 0 de volta na equação temos
f (0) = -4 (0) ^ 2 + 5
f (0) = 5
A altura máxima é 5

Hello, please, I need the answers!! Each year a school booster club holds a dance to raise funds. In the past, the profit of the club makes after paying for the bank and other costs has been modeled by the function p(t) = -16t^2 - 800t - 4000 where t represents the ticket price in dollars. a. What ticket price gives the maximum profit? b. What is the maximum profit? c. What ticket prices would generate a profit of $5000?
Answer:
Step-by-step explanation:
Given the profit a club makes after paying for the bank and other costs modeled by the function
p(t) = -16t^2 - 800t - 4000
t is the ticket price
The maximum profit occurs when dp/dx = 0.
dp/dx = -32t-800
since dp/dx
0 = -32t-800
32t = -800
t = -800/32
t = - 25
Hence ticket price gives the maximum profit is $-25
b) to get the maximum profit, substitute t = -25 into the modelled function
p(t) = -16t^2 - 800t - 4000
p(-25) = -16(-25)² - 800(-25)- 4000
p(-25) = -10000+20000-4000
p(-25) = 6000
Hence maximum profit is $6000
c) To get the ticket prices would generate a profit of $5000, we will substitute p(t) = 5000 and find t
p(t) = -16t^2 - 800t - 4000
5000 = -16t^2 - 800t - 4000
-16t^2 - 800t - 4000 -5000 = 0
16t^2 + 800t + 9000 = 0
Answer:
Step-by-step explanation:
Given the profit a club makes after paying for the bank and other costs modeled by the function
p(t) = -16t^2 - 800t - 4000
t is the ticket price
The maximum profit occurs when dp/dx = 0.
dp/dx = -32t-800
since dp/dx
0 = -32t-800
32t = -800
t = -800/32
t = - 25
Hence ticket price gives the maximum profit is $-25
b) to get the maximum profit, substitute t = -25 into the modelled function
p(t) = -16t^2 - 800t - 4000
p(-25) = -16(-25)² - 800(-25)- 4000
p(-25) = -10000+20000-4000
p(-25) = 6000
Hence maximum profit is $6000
c) To get the ticket prices would generate a profit of $5000, we will substitute p(t) = 5000 and find t
p(t) = -16t^2 - 800t - 4000
5000 = -16t^2 - 800t - 4000
-16t^2 - 800t - 4000 -5000 = 0
t^2 + 50t + 562.5= 0
Factorize
-50±√2500-4(562.5)/2
t = -50±√2500-2250)/2
t = -50±15.81/2
t = -65.81/2 and -34.19/2
t = -32.91 and -17.09

6/3 + ( -1/6) =
I dont know the answer help please
Answer:
The answer is 11/6! Hope this helped!
Steps:
6/3 + (-1/6)
apply rule --> a + (-b) = a - b
6/3 + (-1/6) = 6/3 - 1/6
= 6/3 - 1/6
6/3 = 2
= 2 - 1/6
2 = 6 x 2 over 6
= 6 x 2 over 6 - 1/6
= 12/6 - 1/6
apply fraction rule --> a/c - b/c = a - b over c
12/6 - 1/6 = 12 - 1 over 6
= 12 - 1 over 6
= 11/6
