For the first one, divide the figure into shapes you know how to use. This one can be turned into 2 rectangles and 1 square. Find the area (length*width) of each new shape and add them together. For example the rectangles would have an area that is 31*23 or 713 m.

For the second one do the same. It is 1 rectangle and 2 triangles. The area of a rectangle (length*width) in this case would be 24*8 or 192 cm and the area of the triangles are 1/2*base*height (you need to use the Pythagorean theorem to find the other length of the triangle) and add up the areas to get the total.

To find the surface area of the last one, there are 6 sides. The area of two of the sides are 15*4. Two of the sides are 15*3. The last two sides are 4*3. Add the areas up to find the total surface area.

Hope this helps! :)

If f(x) and its inverse function, f^-1(x), are both plotted on the same coordinate plane, what is their point of intersection?
Romashka-Z-Leto [24]

Answer:

(a, a)

Step-by-step explanation:

actually there are two cases, don't have intersection and have. if have intersection, then they intersect at line y = x or point (a, a) by definition of inverse function.

Please help I don’t get this
mina [271]

Answer:

H = 11m

Step-by-step explanation:

As we know, volume = length * breadth/width * height

Given,

length = 6m

Breadth/width = 3 1/2 or 3.5

Height = ?

So, l * b * h = v

=> 6m * 3.5m * h = 231m

=> 21m * h = 231m

=> h = 231m /21m = 11m

Therefore, height = 11m / 11metres

Hope this helps

To estimate rhe difference below,would you round the numbers to the nearest ten, nearest hundred, or nearest thousand?explain. 8
iogann1982 [59]
To the nearest thousand, because when you are estimating numbers, you always round to the nearest higher place (like the nearest tenth if comparing 26 and 18).

Only external forces affect the motion of a system, according to Newton's first law. ... force applied to a car produces a much smaller acceleration than when ... Newton's second law states that a net force on an object is responsible for its ... A 1.0-kg mass thus has a weight of 9.8 N on Earth and only about 1.7 N on the Moon.

Given the inequality below:<br><br> 3x-y&gt;4<br><br> Which is the graph of the solution set?
OLga [1]

Answer:

A shaded region below a dashed line (y <3x-4)

Step-by-step explanation:

For linear inequalities, we have shaded regions below or above a dashed or solid or continuous line represented by an inequality.

Their graphs are called region graphs. Those regions are only enclosed ones if before the sign of inequality it is included both variables. Like x²+y²<1, |x+y|<1, etc.

In this case what we have here is an open region, as the graph below shows.

3x-y>4 =-y>4-3x∴y<3x-4

Setting a value for x

3x-4=0

3x=4

3x/3=4/3

x=4/3 (slope)

(4/3,0)
