A 2-column table has 5 rows. The first column is labeled x with entries negative 2, negative 1, 0, 1, 2. The second column is la

Answer:

f(x) = 3(2)^x

Step-by-step explanation:

The Table is:

<u>x</u> <u>f(x)</u>

-2 3/4

-1 3/2

0 3

1 6

2 12

The exponential funtion has the next form:

f(x) = a(b)^x

At x = 0, f(x) = a. Then, a = 3

Isolating b from the equation:

f(x)/a = b^x

ln(f(x)/a) = x*ln(b)

[ln(f(x)/a)]/x = ln(b)

At x = 1, f(x) = 6. Then:

[ln(6/3)]/1 = ln(b)

ln(2) = ln(b)

2 = b

Therefore, the function is f(x) = 3(2)^x

You Are Planting a garden in the shape of an equilateral triangle as shown in the diagram. You want to find the area of the gard

S_A_V [24]

Answer:

Area of the garden = 16 $\sqrt{3}$ ft²

Step-by-step explanation:

Given:

Base of garden = 8 Ft

Find:

Area of the garden = ?

First, we have to find height of the triangle.

$Height = \sqrt{8^2-4^2}\\\\Height = \sqrt{64-16}\\\\Height = \sqrt{48}\\\\Height = 4\sqrt{3}\\$

Computation of area of the garden:

Area of the garden = 1/2 × b × h

Area of the garden = 1/2 × 8 × 4 $\sqrt{3}$

Area of the garden = 16 $\sqrt{3}$ ft²

the points (0,1), (1,5), (2,25), (3,125) are on the graph of a function which equation represent that function

8090 [49]

f(x) = $5^{x}$

note the range is {1, 5, 25, 125 } which can be expressed as

{ $5^{0}$ , $5^{1}$ , $5^{2}$ , $5^{3}$ }

the exponents being the domain { 0, 1, 2, 3 }

thus f(x) = $5^{x}$ an exponential function

Consider the following: A medical researcher wants to determine the effects of pH (a measure of alkalinity or acidity, with pure

natita [175]

Answer:

See below

Step-by-step explanation:

<h3>Continuation of the question</h3>

<u>Data in the table:</u>

<u>PH 4 5 6 7 8 9 10 11 </u>

<u>Bacteria 116 120 131 136 141 151 148 163</u>

<em>Create a scatter plot to represent the data: Based on the data and your scatter plot, what do you think a good linear function would be to represent the data?</em>

<h3>Solution</h3>

<em>See attached for scatter plot</em>

We can see the chart is close to linear function. Let's build one based on data in the table

<u>The line will be in the form of:</u>

y = mx + b

<u>If we use two points and get the equation</u>

(4, 116) and (8, 141)

<u>Finding the slope:</u>

m = (141-116)/(8-4) = 25/4 = 6.25

<u>Then, finding y-intercept:</u>

116 = 6.25*4 + b
b = 116 - 25 = 91

<u>So the line is:</u>

y = 6.25x + 91

<em>Note: This is approximate best fit graph and it is attached as well. Exact formula for the line is built by using different method and is very close to the one above</em>
