A diagonal line labelled CD intersects a horizontal line labelled AB at point E forming an angle AEC. 

Mathematics

Answer: point E

Step-by-step explanation:

We know it is point E for 2 reasons.

(1) The problem actually tells us that the 2 lines intersect at point E. The vertex of an angle is always the intersection of two different lines (or parts of lines) unless it is a straight (180 degrees) angle.

We know this is not a straight angle because we have a diagonal line intersecting a horizontal line.

(2)  The name of the angle is given as 'angle AEC'. The middle letter of an angle name is always the vertex point of the angle.

I hope this helps.

Which vector best describes the translation below?
Nimfa-mama [501]
<h3>Answer: Choice A)  <9,0></h3>

Explanation:

Focus on one of the points in the figure on the left. Let's say we go for the upper left corner point (-7, 4)

Notice it moves to the corresponding image point (2,4). It has shifted 9 units to the right to follow the translation rule (x,y) \to (x+9, y). We've added 9 to the x coordinate, and the y coordinate stays the same.

This notation can be shortened to <9, 0>

In general, the notation (x,y) \to (x+a, y+b) is shortened to the translation vector notation < a, b >. In this case, a = 9 and b = 0.

Answer=1.335 or 1 67/200

813 field goals
1422 attempts

An oil tank in the shape of a cylinder has a diameter of 40 feet and a height of 32 feet. Which expression can be used to find t
Volgvan

The volume of a cylinder is pi*r^2*h

The radius is half the diameter, so 40/2=20, and the radius is 20 ft.

Plugging in: pi*20^2*32=pi*400*32=12800pi=40212.38597

So the volume is about 40212.4 ft^3 and the expression we used is pi*20^2*32

Hope this helped!

Write the equation of the line that has an undefined slope and passes through the point (4,7).
valentinak56 [21]
<h3>Answer is   x = 4</h3>

There is no y as part of the equation. It is a vertical line through 4 on the x axis. Every point on this line has an x coordinate of 4. Recall that all vertical lines have undefined slopes. I picked 4 because it is the x coordinate of the given point (4,7).
