Can Someone Explain How They Got The Correct Answer?

Answers

Answer 1

Answer:

Step-by-step explanation:

We can see that we need to plug in 2 for x in the first equation

We can also see that when x=2 we need to use the second part of the piecewise (because this one works when x is greater than or equal to 2)

so we have

3*(4*2+1)= 27

for g(x) we need to plug in x=1

we use the first piecewise equation because it's valid when x is less than 3

4(1²+2)=12

take their sum 27+12= 39

Answer 2

Answer:

39

200 ft

Step-by-step explanation:

Answer:

200 [tex]cm^2[/tex]

Step-by-step explanation:

The surface area is the 2-dimensional distance around a 3-dimensional figure. In essence, if one was going to wrap a figure in paper, the surface area is the amount of paper one would need. To calculate the surface area one needs to find the area of each face of the figure, then add up all of the values.

[tex]5*11 = 55\\\\5 * 11 = 55[/tex]

[tex]6*11 = 66[/tex]

[tex]\frac{4*6}{2} = 12\\\\\frac{4*6}{2}=12[/tex]

[tex]55+55+66+12+12=200[/tex]

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (1, 2) ← 2 points on the line

Answer:

[tex]16\sqrt{3}\:\mathrm{units^2}[/tex]

Step-by-step explanation:

The area of an equilateral triangle with side length [tex]s[/tex] is equal to [tex]\frac{\sqrt{3}}{4}s^2[/tex]. Since the perimeter is 24 units and there are three equal sides to an equilateral triangle, each side is [tex]24\div 3=8[/tex] units.

Substituting in this value, we get:

[tex]\frac{\sqrt{3}}{4}8^2=\frac{64\sqrt{3}}{4}=\boxed{16\sqrt{3}}[/tex]

y=2x-3 is the answer.

Note that y=2(x+3) is the same as y=2x+6, which has a slope of 2. Any parallel line must also have a slope of 2, so the answer must be either C or D. Since option D is the same line and will have points in common with the original line, the answer is C.
