Given the function f(x)=5x6−3x5+6x4+6 What is the value of f(3)?

1 answer:

8 0

The answer is $f(3)=3,408.$

To solve this problem, just plug $3$ into the function and simplify.

$f(x) = 5x^6 - 3x^5 + 6x^4 +6 \\
f(3) = 5(3)^6 - 3(3)^5 + 6(3)^4 +6 \\
= 5(729) - 3(243) + 6(81) + 6 \\
= 3645 - 729 + 486 + 6 \\
= 3408

Answer:

$a_n = 2+6(n-1)$

Step-by-step explanation:

Explicit Arithmetic Formula: $a_n=a_1 + d(n-1)$

a₁ is 1st term in sequence

d is common difference

n is term number

Step 1: Find d

d = 8 - 2 = 6

Step 2: Plug in variables into formula

$a_n = 2+6(n-1)$

PLEASE HELP!!! Two towns are 1100 miles apart. A group of hikers starts from each town and walks down the trail toward each othe

Vinvika [58]

Answer:

2.54 miles/hr

2.04 miles/hr

Step-by-step explanation:

Given: Distance between the two towns = 1100 miles

Difference between speeds = $\frac{1}{2}$ miles/hr

Total time when they meet = 240 hours

To find:

Let distance traveled by first group = $x$ miles.

Now, the distance traveled by second group = (1100- $x$ ) miles/hr

The relation between Speed, Time and Distance is given as:

$\text{Speed =} \dfrac{\text{Distance}}{\text{Time}}$

Let speed of first group = $S_1$

$S_1 = \dfrac{x}{240}$

Let speed of second group = $S_2$

$S_2 = \dfrac{1100-x}{240}$

As per question, $S_1$ = $S_2$ + $\frac{1}{2}$

$\dfrac{x}{240} = \dfrac{1100-x}{240} + \dfrac{1}{2}\\\Rightarrow \dfrac{x}{240} - \dfrac{1100-x}{240} = \dfrac{1}{2}\\\Rightarrow \dfrac{x-1100+x}{240} = \dfrac{1}{2}\\\Rightarrow 2x - 1100 = 120\\\Rightarrow 2x = 1220\\\Rightarrow x = 610 ft$
