Answer:

Part A) Is a square

Part B) Is a rectangle

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The figure show a rectangular prism with a square base

Part A) A cross section formed by a plane that intersects the prism parallel to its base would take the shape of a

we know that

A cross section is the intersection of a figure in three-dimensional space with a plane

A plane parallel to the base of a rectangular prism will intersect a cross section that is the same shape as its bases.

The cross section is a square

Part B) A cross section formed by a plane that intersects the prism perpendicular to its base would take the shape of a

we know that

A plane perpendicular to the base of a rectangular prism will intersect a cross section that is the same shape as its lateral faces

The cross section is a rectangle

a crane lifts a pallet of concrete blocks 7 ft from the back of the truck . the truck driver away and the crane lowers the palle

n200080 [17]

Answer:

4 ft down as per the image attached.

5 ft down as per the question statement.

Step-by-step explanation:

Given that:

A Pallet of concrete blocks is at the back of a truck.

The pallet is lifted by the crane to a height of 8 ft (as per image attached ) or 7 ft (as per question statement) and then the truck moves forward.

Now, the pallet is lowered down to a distance of 12 ft.

To find:

The final position of the pallet relative to the position from the back of the truck?

Solution:

If we closely look at the figure attached, it can be interpreted that the pallet is taken 8 feet above and then 12 feet down.

Therefore, if we subtract 8 feet from 12 feet, we will have our answer.

So, the position of the pallet with respect to its position in the truck is =

12 ft - 8 ft = 4 ft down.

If we consider the question statement:

12 ft - 7 ft = 5 ft down

Find the solutions of 6(2-7x)+x(7x-2=0)

azamat

$6(2-7x)+x(7x-2)=0$

Use distributive property: a(b - c) = ab - ac

$(6)(2)-(6)(7x)+(x)(7x)-(x)(2)=0\\\\12-42x+7x^2-2x=0\\\\7x^2-44x+12=0\\\\7x^2-42x-2x+12=0\\\\7x(x-6)-2(x-6)=0\\\\(x-6)(7x-2)=0\iff x-6=0\ \vee\ 7x-2=0\\\\x-6=0\ \ \ |+6\\\\x=6\\\\7x-2=0\ \ \ |+2\\\\7x=2\ \ \ |:7\\\\x=\dfrac{2}{7}$

Answer:\ $x=6\ \vee\ x=\dfrac{2}{7}$

12x+3y=6

Paul [167]

For this all you have to do is plug in the x and y values into the equation and see if it is a true statement. If it's true then it's on the line. The x value is 2 and the y is -4.

12x + 3y = 6
12 (2) + 3 (-4) = 6
24 -12 = 6
12 = 6

The statement 12=6 is not a true statement so that point is not on the line.
