Find the first Taylor polynomial T1(x) for f(x)=exp(x) based at b=0:
avanturin [10]

Answer:

f(x) = 1 + x + (x²/2!) + (x³/3!) + ....... = Σ (xⁿ/n!) (Summation from n = 0 to n = ∞)

Step-by-step explanation:

f(x) = eˣ

Expand using first Taylor Polynomial based around b = 0

The Taylor's expansion based around any point b, is given by the infinite series

f(x) = f(b) + xf'(b) + (x²/2!)f"(b) + (x³/3!)f'''(b) + ....= Σ (xⁿfⁿ(b)/n!) (Summation from n = 0 to n = ∞)

Note: f'(x) = (df/dx)

So, expanding f(x) = eˣ based at b=0

f'(x) = eˣ

f"(x) = eˣ

fⁿ(x) = eˣ

And e⁰ = 1

f(x) = 1 + x + (x²/2!) + (x³/3!) + ....... = Σ (xⁿ/n!) (Summation from n = 0 to n = ∞)

Beth and her sisters are going to the state fair. Each ride costs $7, and each exhibit costs $4. The table shows the number of r
Maru [420]

Answer:

7x + 3y </=8

Step-by-step explanation:

Let x represent the number of rides Beth rides and y represent the number of exhibits she views

Each ride costs $7 to ride and each exhibit costs $3 to view

This means that x rides will cost x × 7 = $7x

Also, if she views y exhibits, the cost will be y × 3 = $3y.

Total cost of x rides and y views will be 7x + 3y

if she has at most $98 to spend at the fair, it means that all she can spend must be lesser than or equal to $98

The required expression will be

7x + 3y </=8

klio [65]

Answer:

13 ounces

Step-by-step explanation:

Since the package ended up costing $5.81, we subtract the starting cost of 6 ounces, which is $4.90.

We end up with $0.91. Since each additional ounce is $0.13, we divide 0.91 by 0.13.

This gives us seven, which is the amount of additional ounces. Since Mrs. Washington paid 4.90 for the first six ounces and then there were an additional 7 ounces, we add 6 plus 7.

The answer is 13 ounces. Hope this helps!
