26mm² is area of complex figure.

Answer:

solution:in rectangle

length[l]=6mm

breadth [b]=4mm

area of rectangle=l×b=6×4=20mm²

again in triangle

height[h]=6/2=3mm

base[b]=4mm

area of triangle =1/2 b×h=1/2×3×4=6mm²

total area of composite figure=20mm²+6mm²

=26mm²

Answer:

  • 25 mm²

Step-by-step explanation:

<u>The pink figure has dimensions:</u>

  • 42 mm x 28 mm and the area of 1225 mm²

<u>The blue figure has dimensions:</u>

  • 6 mm x 4 mm

<u>The scale factor is the ratio of corresponding sides:</u>

  • k = 4/28 = 6/42 = 1/7

<u>The area's scale factor is </u>

  • k² = 1/49

<u>The area of the reduced figure is:</u>

  • 1225*1/49 = 25 mm²

<u><em>note</em></u><em>. It was answered based on the additional information given in the comments (though 41 mm should be 42 mm)</em>

Is domain of f(x,y) = 1 + (4 -y^2)^1/2 open, closed or neither<br><br> is it bounded or unbounded?
omeli [17]

Answer:

Closed and Bounded.

Step-by-step explanation:

Hi there!

1) Let's start by finding the values in which the function is defined. Remember that this can be rewritten:

f(x,y) = 1 + (4 -y^2)^{\frac{1}{2}} \:id\:est\:f(x,y)=1+\sqrt{(4 -y^2)}

Since every quadratic root are defined for values \geq 0  then, this help us to understand that we need calculate what interval this Domain is:

4-y^{2} \geq 0\\4-y^{2}-4\geq -4\\-y^{2}\geq-4 \\y^{2}\leq4\\-2\leq y\leq 2

D=[-2,2]

2) Graphically speaking, the domain is closed. For the values -2 and 2 are included, and bounded.

Bounded functions have all of their points contained by some circle origin centered. Check it out below.

The movie started at 6:32 p.m. and ended at 9:48 p.m. How long did the movie last?
lapo4ka [179]
First, add hours until the difference is less than an hour. You can add 3 hours on to make it 9:32 p.m. Then, add minutes on until it's the exact time. from 9:32 to 9:48, you can add 16 minutes, so the total time in the movie was 3 hours, 16 minutes.

34.7% of city employees ride the bus to work. Last year, 5.2% of city employees rode the bus to work. What is the relative chang
DaniilM [7]

Answer:

5.67\%

Step-by-step explanation:

The relative change is defined by the following equation:

Relative\hspace{3}change=\frac{x-x_r_e_f_e_r_e_n_c_e}{x_r_e_f_e_r_e_n_c_e}   (1)

Where:

x=Value\hspace{3}of\hspace{3}indicator\hspace{3}in\hspace{3}period\hspace{3}2

x_r_e_f_e_r_e_n_c_e=Value\hspace{3}of\hspace{3}indicator\hspace{3}in\hspace{3}period\hspace{3}1

With this in mind, let's replace the values in the equation (1):

Relative\hspace{3}change=\frac{34.7-5.2}{5.2}=\frac{29.5}{5.2}=5.673076923\approx5.67\%
