Kyle is purchasing a refurbished phone. He is looking at the phone models 4, 5, and 6, with a protective case in red (R), blue (
konstantin123 [22]

Answer:

The choices Kyle has are option D.)  {4R, 4B, 4C, 5R, 5B, 5C, 6R, 6B, 6C}

Step-by-step explanation:

The choices available to Kyle either of the models 4, or 5 or 6 and each model can have a protective case which can be either red(R) or blue(B) or camo(C).

So Kyle can have model 4 in red protective case, 4R, or model 4 in blue protective case(4B), or model 4 in camo protective case (4C) or

Kyle can have model 5 in red protective case, 5R, or model 5 in blue protective case(5B), or model 5 in camo protective case (5C) or

Kyle can have model 6 in red protective case, 6R, or model 6 in blue protective case(6B), or model 6 in camo protective case (6C).

So the choices Kyle has are option D.)  {4R, 4B, 4C, 5R, 5B, 5C, 6R, 6B, 6C}

use Taylor's Theorem with integral remainder and the mean-value theorem for integrals to deduce Taylor's Theorem with lagrange r
Vadim26 [7]

Answer:

As consequence of the Taylor theorem with integral remainder we have that

f(x) = f(a) + f'(a)(x-a) + \frac{f''(a)}{2!}(x-a)^2 + \cdots + \frac{f^{(n)}(a)}{n!}(x-a)^n + \int^a_x f^{(n+1)}(t)\frac{(x-t)^n}{n!}dt

If we ask that f has continuous (n+1)th derivative we can apply the mean value theorem for integrals. Then, there exists c between a and x such that

\int^a_x f^{(n+1)}(t)\frac{(x-t)^k}{n!}dt = \frac{f^{(n+1)}(c)}{n!} \int^a_x (x-t)^n d t = \frac{f^{(n+1)}(c)}{n!} \frac{(x-t)^{n+1}}{n+1}\Big|_a^x

Hence,

\int^a_x f^{(n+1)}(t)\frac{(x-t)^k}{n!}d t = \frac{f^{(n+1)}(c)}{n!} \frac{(x-t)^{(n+1)}}{n+1} = \frac{f^{(n+1)}(c)}{(n+1)!}(x-a)^{n+1} .

Thus,

\int^a_x f^{(n+1)}(t)\frac{(x-t)^k}{n!}d t = \frac{f^{(n+1)}(c)}{(n+1)!}(x-a)^{n+1}

and the Taylor theorem with Lagrange remainder is

f(x) = f(a) + f'(a)(x-a) + \frac{f''(a)}{2!}(x-a)^2 + \cdots + \frac{f^{(n)}(a)}{n!}(x-a)^n + \frac{f^{(n+1)}(c)}{(n+1)!}(x-a)^{n+1}.

50 points!! Please help!! Will mark brainliest and random answers will be reported
Triss [41]

Answer:

<em>In </em><em>the </em><em>above</em><em> </em><em>figure</em>

<em>both </em><em>the </em><em>sides </em><em>are </em><em>equal</em><em> </em><em>then</em><em> </em><em>angle </em><em>between</em><em> </em><em>them </em><em>will </em><em>also </em><em>equal</em>

<em>so,</em>

<em>(</em><em>2</em><em>x</em><em>+</em><em>2</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>2</em><em>x</em><em>+</em><em>2</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>3</em><em>x</em><em>+</em><em>1</em><em>)</em><em> </em><em>=</em><em> </em><em> </em><em>1</em><em>8</em><em>0</em>

<em>7</em><em>x</em><em> </em><em>+</em><em> </em><em>5</em><em> </em><em>=</em><em> </em><em>1</em><em>8</em><em>0</em>

<em>7</em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>7</em><em>5</em><em> </em>

<em>x </em><em>=</em><em> </em><em> </em><em>1</em><em>7</em><em>5</em><em>/</em><em>7</em>

<em>x </em><em>=</em><em> </em><em>2</em><em>5</em>

hence angle will (25 *2) +2 =52

other angle is( 25*3)+1 = 76

<em>hope </em><em>it </em><em>helps</em><em> </em><em>and </em><em>your </em><em>day </em><em>will </em><em>fine</em>

The Humphrey family is traveling 1,325 miles for their family vacation. Last year, they traveled 724 miles. They drove 420 miles
Alona [7]

Answer: They have 775 miles left to be traveled

Step-by-step explanation:

Miles required to travel for vacation = 1,325 miles

Miles already traveled = Miles driven this week + miles driven today

= 420 miles + 130 miles

-=550 miles

Miles remaining to be covered =Miles required to travel for vacation --- Miles already traveled

= 1,325 miles - 550 miles

= 775 miles
