Answer:

The relation represents a growth when b>1 and a decay when 0<b<1

Step-by-step explanation:

Any function in the form f(x)= a(b^x), where a > 0, b > 0 and b not equal to 1 is called an exponential function with base b. If 0 < b < 1.  It is an example of an exponential decay. The general shape of an exponential with b > 1 is an example of exponential growth. An exponential function is expressed in the form y=a(b^x) The relation represents a growth when  b >1 and a decay when 0<b<1.

The table below shows the relationship between the number of teaspoons of baking powder in a mix and the height of fudge brownie
rosijanka [135]

Answer:

Option A. y=0.28x+0.75

Step-by-step explanation:

Let

y -----> the height of fudge brownies in centimeters

x ----> teaspoons of baking powder

step 1

Find the slope

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

take the points

(5,2.15) and (6,2.43)

substitute the values

m=\frac{2.43-2.15}{6-5}

m=\frac{0.28}{1}=0.28

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=0.28

(x1,y1)=(5,2.15)

substitute

y-2.15=0.28(x-5)

Isolate the variable y

y-2.15=0.28x-1.4

y=0.28x-1.4+2.15

y=0.28x+0.75

Find the percent of the area under the density curve where x is more than 3. <br>​
Gekata [30.6K]

Answer:

The percent of the area under the density curve where x is more that 3 is 25 %.

Step-by-step explanation:

Since the density curve is a linear function, the area under the curve can be calculated by the geometric formula for a triangle, defined by the following expression:

A = \frac{1}{2}\cdot (x_{f} - x_{o})\cdot  (y_{f}-y_{o}) (1)

Where:

A - Area, in square units.

x_{f} - x_{o} - Base of the triangle, in units.

y_{f} - y_{o} - Height of the triangle, in units.

The percent of the area is the ratio of triangle areas under the density curve multiplied by 100 per cent, that is:

x = \frac{\frac{1}{2}\cdot (5-3)\cdot (0.25) }{\frac{1}{2}\cdot (5-1)\cdot (0.5) }\times 100\,\%

x = 25\,\%

The percent of the area under the density curve where x is more that 3 is 25 %.
