John is trying to estimate how tall a tree is. the shadow created by the tree is 18 feet long. john is 6 feet tall, and his shad

Alecsey [184]

Make a comparison
$\frac{height}{shadow}= \frac{height}{shadow}$
$\frac{heightof tree}{shadow of three}= \frac{heightofJohn}{shadow of John}$

Plug the numbers into the equation above
h stands for the height of tree
$\frac{heightof tree}{shadow of three}= \frac{heightofJohn}{shadow of John}$
$\frac{h}{18}= \frac{6}{3.5}$

Do cross multiplication
3.5h = 6 × 18
3.5h = 108
h = 108/3.5
h = 30.8571..

to the nearest hundredth
h = 30.86 feet
to the nearest tenth
h = 30.9 feet

Ryder shot a model rocket over an area that consists of two grassy areas, shown in green, and an area with no grass, shown in wh

kolezko [41]

The rocket has a 2/3 chance of landing in the grassy area, 2 out of 3 areas in the total area are grassy. Cross multiply to turn 2/3 into a percentage, and you get 66%. You can also divide 2 by 3 to get a 0.66 chance. Presuming that 0.2, 0.3, 0.4, and 0.6 are your answer options for this equation, i would say 0.6. If not then the answer is 0.66, 66%, or 2/3 chance

Find a power series for the function, centered at c. g(x) = 4x x2 2x − 3 , c = 0

BartSMP [9]

The power series for given function $g(x)=\frac{4x}{(x-1)(x+3)}$ is $g(x)=\sum{_{n=0}^\infty}~x^n(-1+(-\frac{x}{3} )^n)$

For given question,

We have been given a function g(x) = 4x / (x² + 2x - 3)

We need to find a power series for the function, centered at c, for c = 0.

First we factorize the denominator of function g(x), we have:

$\Rightarrow g(x)=\frac{4x}{(x-1)(x+3)}$

We can write g(x) as,

$\Rightarrow g(x)=\frac{1}{x-1}+\frac{3}{x+3}\\\\\Rightarrow g(x)=\frac{-1}{1-x}+\frac{1}{1+\frac{x}{3} }\\\\\Rightarrow g(x)=\frac{-1}{1-x}+\frac{1}{1-(-\frac{x}{3} )}\\$
