In the book The Secret Garden, Mary had never thanked anyone before. How did she thank Martha for the jump rope?

She cried and gave her a hug.

She shook her hand.

She drew her a picture.

She gave her flowers from the garden.

I got this answer a long time ago,

Explanation:

I think that the answer for this one is because I know that she doesn´t draw a picture, and I know that she doesn´t have empathy, and I know that she wouldn´t pick the flowers from the garden, so I think the answer is B- she shook her hand. I hope this helps!

this is the answer , p = 1 + (1/10)x

step-by-step explanation:

we have,

at sea level pressure is 1 atmosphere (i.e at x =0, p0=1 atmosphere)

at depth 23 meters , pressure = 3.3 atmosphere

since the pressure increases at constant rate as the depth increases, so we can write a relation as:

p =p0 +   kx   , where p is the pressure  , p0 is the initial pressure, x is the depth and k is constant rate of increasing.

to find constant rate k, plug p = 3.3 , p0 = 1 and x= 23 meters

we get,

  3.3 = 1 + k * 23

k = 2.3 / 23   = 1/10

so we can write the function formula as:   p = 1 + (1/10)x
