For x7 − 2x6 + 3x2 − 2x + 5 = 0, state the number of complex roots, the possible number of real roots, and the possible rational roots.

1.) 5 complex roots; 1, 3, or 5 real roots
possible rational roots: ±1, ±5
2.) 5 complex roots; 1, 3, or 5 real roots
possible rational roots: ±5 over 2, ±1, ±5
3.) 7 complex roots; 1, 3, 5, or 7 real roots
possible rational roots: ±1, ±5
4.) 7 complex roots; 2, 4, or 6 real roots
possible rational roots: ±1, ±5

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

10 b/c 5*2 =10

step-by-step explanation:

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
