The value 4 represents the horizontal transformation from the graph of the function f(x) = x^2 to the graph of the function g(x).

<h3>What is a function?</h3>

Function is a type of relation, or rule, that maps one input to specific single output.

We have given that parent function

f(x) = x^2

After translation of the parent function

g(x)=(x-4)^2+2

The General equation of parabola along y-axis

y=(x-h)^2+k

The vertex of the function is (h,k).

The given function is an equation of parabola along y-a xis.

By comparing the given function with the general equation of parabola,

The vertex of function f(x) is (0,0).

The vertex of function g(x) is (4,2).

Therefore, h of f(x) is a shift towards the right and then we can get h of g(x) =4.

Hence, the value 4 represents the horizontal transformation from the graph of the function f(x) = x^2 to the graph of the function g(x).

Answer:

about 78 years

Step-by-step explanation:

Population

y =ab^t  where a is the initial population and b is 1+the percent of increase  

    t is in years

y = 2000000(1+.04)^t

y = 2000000(1.04)^t

Food

y = a+bt   where a is the initial population and b is constant increase

    t is in years

b = .5 million = 500000

y = 4000000 +500000t

We need to set these equal and solve for t to determine when food shortage will occur

2000000(1.04)^t= 4000000 +500000t

Using graphing technology, (see attached graph  The y axis is in millions of years), where these two lines intersect is the year where food shortages start.

t≈78 years

327.8 in scientific notation
Allushta [10]

Answer:

3.278 * 10 ^ 2

Step-by-step explanation:

To change a number to scientific notation you:

Move the decimal point to the left to make the number have 1 number before the decimal point.

From there you multiply by 10 to the power 2 the number of decimal points you moved.

So the answer is 3.278 * 10^2

n a study of cell phone use and brain hemispheric​ dominance, an Internet survey was​ e-mailed to 2472 subjects randomly selecte
Leona [35]

Answer:

0.3876<p<0.4389

Step-by-step explanation:

-Given n=2472, \ x=1022 , \ CI=0.99

-We calculate the proportion of surveys returned:

\hat p=\frac{1022}{2472}\\\\=0.4134

For a 99% confidence interval:

z_{\alpha/2}=2.576

#The margin of error is calculated as;

ME=z_{0.005}\times \sqrt{\frac{\hat p(1-\hat p)}{n}}\\\\=2.576\times \sqrt{\frac{0.4134(1-0.4134)}{2472}}\\\\=0.0255

The confidence interval are then:

CI=\hat p\pm ME\\\\=0.4134\pm 0.0255\\\\=[0.3876,0.4389]

Hence, the confidence interval is 0.3876<p<0.4389
