Complete question:
Dada a função exponencial abaixo, se x=1, qual valor de imagem? * a) 1 b) -2 c) 0 d) -1
The function in the image is f(x) = 3^x-1
Answer:
A) 1
Step-by-step explanation:
To solve the exponential function above given that x = 1;
Substitute x = 1 into the exponential function
If x = 1
f(x) = 3^(x - 1)
f(1) = 3^(1 - 1)
f(1) = 3^0
f(1) = 1
Answer:
D.
Step-by-step explanation:
The correct answer to the problem is D.
First we will find the average production for each machine:
For old machine:
(10) / (2) = 5 widgets / hour
For new machine:
(30) / (3) = 10 widgets / hour
We define t:
t = Amount of time in hours:
The equation sought is:
5 + 10 = 75 / t
Clearing we have:
t = (75 / (5 + 10))
t = 5 hours
Answer:
Working together, it will take the two machines to produce 75 widgets about:
t = 5 hours
Answer:It takes 250 g of pasta and 240 ml of sauce to make one batch of spaghetti and it takes 600g of pasta and 700ml of sauce to make one batch of lasagna.
Case 1: Pasta
The chef wants to make spaghetti and lasagna using more than 4000 g of pasta.
S denote the number of batches of spaghetti he makes and L the number of batches of lasagna he makes.
So the equation becomes :
Case 2: Sauce
chef wants to make spaghetti and lasagna using more than 5000 ml of sauce.
S denote the number of batches of spaghetti he makes and L the number of batches of lasagna he makes.
So the equation becomes:
Answer :
The two equations are :
For pasta:
For sauce:
