Arlecino [84]3 years ago
8 0

Answer:

One

Step-by-step explanation:

Line of symmetry of a figure is an imaginary line about which the figure can be divided into two equal halves.

In other words, a line passing the center of the figure about which we can fold the figure into two halves overlapping each other.

For the trapezoid given in the figure, line of symmetry will be a vertical line perpendicular to the parallel sides.

Therefore, The figure has 1 line of symmetry.

The daily demand for ice cream cones at a price of $1.20 per cone is 50 cones. At a price of $2.20 per cone, the demand is 30 co
Lapatulllka [165]

Answer:

<h2>The demand at a price of $1.50 per cone is 44 cones</h2>

Step-by-step explanation:

 let us apply the interpolation formula to solve this problem

we have

\frac{y-y1}{x-x1} =\frac{y2-y1}{x2-x1}

Now let us set the values to the notation above

x= $1.20

x1= $2.20

x2= $1.50

y = 50 cones

y1= 30 cones

y2= ?

y2= \frac{(y-y1)}{(x-x1)} (x2-x1)+y1

Substituting our given data we have

y2= \frac{(50-30)}{(1.2-2.2)} (1.5-2.2)+30\\\\y2=  \frac{20}{-1} (-0.7)+30\\\\y2=   (20*0.7)+30\\y2= 14+30\\y2= 44

the demand at a price of $1.50 per cone is 44 cones

30 72

 

 

Slope 0.732

Int -21.56266667

Regression line is y = 0.732x-21.563 where x represents the latitude and y high temperature

Since slope = 0.732, we get temp increases by 0.8 degree for 1 degree increasenorth in latitude

Hence option c is right

What is the solution of the equation e^xe^2x = 4? Round your answer to the nearest hundredth.
Stells [14]
The equation is:

[e^x] [e^(2x)] = 4

1) Applying property of multiplication of powers wiith same base =>

e ^ (x + 2x) = 4

=> e ^ (3x) = 4

2) Applying logarigth properties

3x = ln(4)

=> x = ln(4) / 3 ≈ 1.38629 / 3 ≈ 0.4621

Answer: x = ln(4) / 3 ≈ 0.4621
