Answer:

B. 4.73 × 10¹⁷

Step-by-step explanation:

(5 × 10⁴)(9.46 × 10¹²)

47.3 × 10⁴ ⁺ ¹²

47.3 × 10¹⁶

That is not an option, so we have to divide 47.3 by 10 or increase the exponent.

47.3 × 10¹⁶ ⁺ ¹

4.73 × 10¹⁷

iren [92.7K]

Answer:6 17/18 hours

Step-by-step explanation:

We are informed that on Monday Katie spent 2 1/6 hours studying while onn Tuesday she spent another 4 7/9 hours studying.

The combined length of time she spent studying will be the addition of the numbers of hours spent studying on Monday and Tuesday. This will be:

= 2 1/6 + 4 7/9

= 2 3/18 + 4 14/18

= 6 17/18

She used a total of 6 17/18 hours studying

Which graph represents the solution set for the quadratic inequality x2 + 2x + 1 > 0?
ipn [44]

Answer:

We have to determine the graph of the given inequality as:

x^2+2x+1>0

on solving this equation we get:

(x+1)^2>0

Since we know that:

(x+1)^2=x^2+1^2+2\times x\times 1\\\\(x+1)^2=x^2+1+2x

Now we know that when x=-1 the value of:

(x+1)^2=0

Also for the value other than -1 the function being a quadratic function will always give a non-zero positive value.

Hence, range of the function in intervals could be written as:

(-∞,-1)∪(-1,∞).

Hence, the graph of the function will be the whole of the number line with a open circle on -1.

Ap calc multiple choice question; attached below<br> please explain how, please!
anygoal [31]

Answer:

C. \frac{f(b)-f(1)}{b-1}=20

General Formulas and Concepts:

<u>Calculus</u>

  • Mean Value Theorem (MVT) - If f is continuous on interval [a, b], then there is a c∈[a, b] such that  f'(c)=\frac{f(b)-f(a)}{b-a}
  • MVT is also Average Value

Step-by-step explanation:

<u>Step 1: Define</u>

f(x)=e^{2x}

f'(c) = 20

Interval [1, b]

<u>Step 2: Check/Identify</u>

Function [1, b] is continuous.

Derivative [1, b] is continuous.

∴ There exists a c∈[1, b] such that f'(c)=\frac{f(b)-f(a)}{b-a}

<u>Step 3: Mean Value Theorem</u>

  1. Substitute:                    20=\frac{ f(b)-f(1)}{b-1}
  2. Rewrite:                        \frac{ f(b)-f(1)}{b-1}=20

And we have our final answer!
