The area of the base = 15 * 15 = 225 m2
ande tharea of each sloping triangular side = 1/2 * 15 * 18 = 135 m2

so total surface area = 225 + 4*135 = 765m2

Hi there.

The answer is g(0) = 3.

Explanation:

Given three functions with specified domains. The first and three functions both do not have x = 0 as a part of the domain. We can clear both functions.

Our main function then is currently —

$g(x) = 3$

You might be wondering how are we gonna find the x-value if there is no x-term?

That is to do nothing. If there is no x-term to substitute then we answer only the constant.

$g(0) = 3$

Answer: -1

Step-by-step explanation:

(2x(x+1)+2x(x-3))/(4x(x-3)(x+1)) = 2x/((x-3)(x+1))

(2x-2)/(2) = 2x

x-1 = 2x

-1 = x

As part of a survey, 1200 people were asked to name their favorite sport to watch. The table below summarizes their answers. Thi

vredina [299]

Answer:

x° is 108°

Step-by-step explanation:

The figure given of the survey of the 1,200 people is the table of values and a corresponding a pie-chart

From the table of values, we have;

The total number of participants in the survey, n = 324 + 360 + 108 + 156 + 96 + 156 = 1,200

The number of the participants in the survey that selected soccer as their favorite sport, sₙ = 360

The fraction of the participants in the survey that selected soccer as their favorite sport, Psₙ = Sₙ/n

∴ Psₙ = 360/1200 = 0.3

Therefore, 0.3, which is equivalent to 30% chose soccer as their favorite sport

To represent the fraction of the survey participants that selected soccer as their favorite sport on a pie chart, 0.3, we note that the sum of the angles at the center of the pie chart is 360°, therefore, the angle that is given to soccer on the pie chart, 'x', is the product of 0.3 and 360° as follows;

x° = 0.3 × 360° = 108°

x° = 108°

A rowing team rowed an average of 15.2 miles per hour with the current and 8.4 miles per hour against the current. Determine the

Luba_88 [7]

Answer:

Team's rowing speed in still water: 11.8 miles per hour.

Speed of the current: 3.4 miles per hour.

Step-by-step explanation:

Let r represent team's rowing speed in still water and speed of current be c.

Rowing speed with current would be $r+c$ and rowing speed against current would be $r-c$ .
