Answer:

The units digit of our number should be and can be any of 0, 2, 4, 6  (four opportunities).

The tens  digit of our number should be and can be any of 0, 2, 4, 6  (four opportunities).

The hundreds digit of our number should be and can be any of 0, 2, 4, 6, 8  (five opportunities).

The thousands digit of our number should be and can be any of 2, 4, 6  (three opportunities).

So, there are 4*4*5*3 = 16*15 = 240  such 4-digits totally even numbers, satisfying the condition.     ANSWER

If f(x)=4x^3 - 6x^2 + 2x - 5, then f(-2) = ___________
Art [367]

f(x)=4x^3 - 6x^2 + 2x - 5

f(-2)


Replace X with -2:

4(-2)^3 - 6(-2)^2 + 2(-2) - 5 =

Calulate the powers:

4(-8) - 6(4) +(-4) -5=

Multiply:

-32 - 24 -4 -5=

Subtract

A culture started with 5000 bacteria. after 7 hours, it grew to 6500 bacteria. predict how many bacteria will be present after 1
spin [16.1K]

6500=7x+5000

6500-5000=7x+5000-5000

1500=7x

1500/7≈214

x≈214

y=19·214+5000

y=9066

answer=9066 bacteria

Look at the table to answer the question.
Alexus [3.1K]

Answer:

Your power function is  y=-2x^{2}

Step-by-step explanation:

The way I found it was.

0=0,  so, the function multiply by zero, and have no other term to add

A number (one in a case) gives as a result: -2.  So, one, elevated to ANY power results in one, every time. So, I have 1, as a factor and -2 as a result. One is as well a factor that delivers a result equal to the other factor. (3)(1)=3 , (8987)(1)=8987. So, the other factor must be -2

Then I checked all the table, and the results were consistent.
