1point) let h be the set of all points in the second and fourth quadrants in the plane v that is, h- (e, y)y 0) is h a subspace of the vector space v? r2 1. does h contain the zero vector of v? choose 2. is h closed under addition? if it is, enter closed. if it is not, enter two vectors in h whose sum is not in h, using a comma separated list and syntax such as 3. is h closed under scalar multiplication? if it is, enter closed. if it is not, enter a scalar in r and a vector in h whose product is not in h, using a comma separated list and syntax such as 2, 3, 4> 4. is h a subspace of the vector space v? you should be able to justify your answer by writing a complete, coherent, and detailed proof based on your answers to parts 1-3 choose

Step-by-step explanation:

What level of math is this?

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
