How many three-digit numbers can you make if you are not allowed to use any other digits except 4 and 0?
kozerog [31]

Answer:

There is a slight problem with this question

Do numbers starting with "0" count as a digit position

I would say no, thus the answer is 4...

if you are allowed to use 0 then the answer is 8

in other words if the question was using only 4's and 1's then the answer would be 8

Helpppp plzzzzz :/ :(
Alex73 [517]

Answer:

Step-by-step explanation:

For this you will start at negative 3 then go up 5 spaces and to the right 4 times. Once you run out of space in one direction go in the opposite doing the opposite steps. Going down 5 times and to the left 4 times. If you need any more help with these, I'll be glad to help as I am learning these in class right now. The way to determine which way your going is on the slope. The slope in those equations is the number before x. The coefficient. When the numerator(y axis) is positive, that means you go up on the graph by the number shown. If its a negative go down. If the denominator (x-axis) is a positive that means you go to the right by the number shown. If it's a negative you go to the right. The number all the way on the right, in this case the -3, that is the y intercept.

Find the area of an octagon with a radius of 6 meters
never [62]

A regular octagon has all its eight sides congruent. The line segments joining each of the vertices of a regular octagon to its center are called the radii of the octagon. These 8 radii divide a regular octagon into 8 congruent isosceles triangles. Area of each isosceles triangle is

A_{triangle}=\dfrac{1}{2}a^2\sin \alpha,

where a is length of the side of the octagon and \alpha is the angle between two radii of the octagon.

In regular octagon

\alpha=\dfrac{360^{\circ}}{8}=45^{\circ}.

Then the area of regular octagon is

A_{octagon}=8A_{triangle}=8\cdot \dfrac{1}{2}a^2\sin \alpha=4\cdot (6)^2\cdot \sin 45^{\circ}=4\cdot 36\cdot \dfrac{\sqrt{2}}{2}=72\sqrt{2} sq. m.

Answer: A_{octagon}=72\sqrt{2} sq. m.

Find the missing length indicated
12345 [234]

Answer:

x = 960

Step-by-step explanation:

x=√{576×(576+1024)}

or, x = √(576×1600)

or, x = √576×√1600

or, x = 24×40

or, x = 960
