2) Mr. Riley dove off a cliff that was 30 feet above the surface of the water and descended a total of 100 feet. Which of the equations below can be used to determine his elevation at the bottom of his dive?a) 30 + 100
b) 30-100
C) 30 + (-100)
d) Both b and c

Answers

Answer:

Step-by-step explanation:

Mr.Riley was 30 feet above the water, which means he is at +30 above sea level. If he descends 100 feet, that means he goes 100 feet lower then that. 30 - 100 is equal to -70. He is 70 feet under water after he dived. You do not need to know the answer, but it helps to visualize the problem you have, therefore, finding the answer

Find the Taylor series for f(x) centered at the given value of a. [Assume that f has a power series expansion. Do not show that Rn(x) ? 0.]f(x) = 10/x , a= -2f(x) = \sum_{n=0}^{\infty } ______Find the associated radius of convergence R.R = ______

Answers

Rewrite $f$ as

$f(x)=\frac{10}x=-\frac5{1-\frac{x+2}2}$

and recall that for $|x|<1$ , we have

$\displaystyle\frac1{1-x}=\sum_(n=0)^\infty x^n$

so that for $\left|\frac{x+2}2\right|<1$ , or $|x+2|<2$ ,

$f(x)=-5\displaystyle\sum_(n=0)^\infty\left(\frac{x+2}2\right)^n$

Then the radius of convergence is 2.

Final answer:

The Taylor series for the function f(x) = 10/x, centered at a = -2, is given by the formula ∑(10(-1)^n*n!(x + 2)^n)/n! from n=0 to ∞. The radius of convergence (R) for the series is ∞, which means the series converges for all real numbers x.

Explanation:

Given the function f(x) = 10/x, we're asked to find the Taylor series centered at a = -2. A Taylor series of a function is a series representation which can be found using the formula f(a) + f'(a)(x-a)/1! + f''(a)(x-a)^2/2! + .... For f(x) = 10/x, the Taylor series centered at a = -2 will be ∑(10(-1)^n*n!(x + 2)^n)/n! from n=0 to ∞. The radius of convergence R is determined by the limit as n approaches infinity of the absolute value of the ratio of the nth term and the (n+1)th term. This results in R = ∞, indicating the series converges for all real numbers x.

The mass of Box A and Box B is 0.6 kg. The mass of Box A and Box C is 1.3 kg.Box C is 3 times as heavy as Box B. Find the mass of Box A.

Answers

Answer:

A=0.25

B=0.35

C=1.05

Step-by-step explanation:

1. A+B=0.6

2. A+C=1.3

3. C=3B

2 subtract 1:

C-B=0.7

3 substituted:

3B-B=0.7
B=0.35
C=0.7+0.35=1.05
A=0.6-0.35=0.25

Find the coordinates of B' after a reflection across the x-axis. show your work

Answers

Answer:

B'(8, 6)

Step-by-step explanation:

Coordinates of point B = (8, -6)

Reflection across the x-axis results in:

(x, y) → (x, -y)

Coordinates of B'

(8, -6) → (8, -(-6)) = (8, 6)

How do you know if a relationship between two quantities is NOT proportional?

Answers

Answer:

Just divide y by x for every single term, and if they get the same quotient, they are proportional.

For example:

x y

2 4 Divide 4/2. This equals 2.

6 12 Divide 12/6. This equals 2.

4 8 Divide 8/4. This equals 2.

Therefore, these quantities are proportional.
