Approximate the solution to the equation above using three iterations of successive approximation. Use the graph below as a star

n200080 [17]

Answer:

Step-by-step explanation:

<u>Approximate Roots of Functions:</u>

We are required to find the root of

$\displaystyle 5^{-x}+7=\ 2x+4$

Let's construct a function

$\displaystyle f(x)=\ 5^{-x}+7-2x-4$

Reducing:

$\displaystyle f(x)= 5^{-x}-2x+3$

The equation will have a solution when f(x)=0. We'll start from the approximate crossing point given in the graph (x=1.5)

$\displaystyle f(1.5)=5^{-1.5}-2(1.5)+3\ =0.089$

We'll move up on x=1.52

$\displaystyle f(1.52)=5^{-1.52}-2(1.52)+3=\ 0.046$

We are closer to the solution, let's try some more up

$\displaystyle f(1.54)=5^{-1.54}-2(1.54)+3=\ 0.0038$

This value x=1.54 is close enough to the solution of the original equation

From the options given, $\frac{25}{16}$ is the closest to our solution

$\boxed{Answer:\ x=25/16}$

Find the 4th term if the sequend in which a1 = 2 and an+1 = -4an + 2.

enyata [817]

The notation, more or less indicates that, the first value in the sequence is 2, the next term's value, will be "current value, times -4 and plus 2"

thus $\bf \begin{array}{ccllll}
a_n\ term&&value\\
\text{\textemdash\textemdash\textemdash}&&\text{\textemdash\textemdash\textemdash}\\
a_1&&2\\
a_2&-4a_1+2&-4(2)+2\implies -6\\
a_3&-4a_2+2&-4(-6)+2\implies 26\\
a_4&-4a_3+2&-4(26)+2\implies -102
\end{array}$

What's 10% ÷ 0.1%. I can't figure out why it's 10,000%.

Debora [2.8K]

Answer:

Step-by-step explanation:

10 % = 10/100 = .1

.1 % = .1 /100 = 1/1000 =.001

.1 ÷.001 =

10/100 ÷ 1/1000

Copy dot flip

10/100 * 1000/1 =

10000/100

100

Now we need to change it to percent

Multiply by 100%

100 * 100 %

10000%

Sum of 1/2*3 +1/3*4 +1/4*5 ..1/99*100

geniusboy [140]

Answer:

11∗2+13∗4+15∗6+⋯+199∗100=?

=(1−12)+(13−14)+(15−16)+⋯+(199−1100)

=(1+13+15+17+⋯+199)−(12+14+16+⋯+1100)

=(1+13+15+17+⋯+199)−12(1+12+13+⋯+150)

=∑k=15012k−1−∑k=15012k
