We assume that you don't want to count numbers that start with 0, so there are 4 possible first digits and 5 possible digits in each of the remaining places.

4*5^3 = 500 . . . . total number of 4-digit numbers using only even digits

_____
The list of them would be ...
2000, 2002, 2004, 2006, 2008, 2020, ..., 8868, 8880, 8882, 8884, 8886, 8888

What are the X and Y intercepts of y= -2(x-4)2 +3

kari74 [83]

Answer: x-intercepts are ( 2.775,0) and (5.225,0)

And y-intercept is (0,-29)

Step-by-step explanation:

Here the given equation is,

$y = -2(x-4)^2+3$

For x-intercept, y = 0,

Put y = 0 in the above equation of parabola,

We get, $-2(x-4)^2 + 3 = 0$

$-2(x^2+16+8x) + 3 = 0$

$-2x^2-32-16x + 3 = 0$

$-2x^2-16x -29 = 0$

By solving this equation,

We get, x = 2.775 or x = 5.225

Therefore, x-intercept of the given parabola are (2.775, 0) and (5.225,0)

Now, for y-intercept, x = 0

By putting x = 0 in the given equation of parabola,

We get, y = -29

Thus, y-intercept of the given parabola = (0,-29)

The art teacher had 1321 pipe cleaners for a project

She used 477 with the fourth age

A parent donated 2,600 pipe cleaners

Therefore the number of pipe cleaners she have left can be calculated as follows

= 1321-477+2600

= 844 + 2600

= 3,444
