Answer 1

Answer:

Blood of specific gravity 1.0 flows through an

artery in the neck of a giraffe from its heart to

the head. If pressure at the beginning of the

artery (outlet of the heart) is equal to 0.212 m of

mercury, the pressure at the end of the artery,

when the head is 2.4 m above the heart, is

Answer 2

Step-by-step explanation:

5.

(4/5)²+(1/4)-³

=(16/25)+(1/(1/4)³)

=(16/25)+64

=(16+1600)/25

=1625/25

=65

6.((7⁶×7⁶×7²)/7⁵)×7²××7³

=7⁶+⁶+²+²+³-5

=7¹⁹-⁵

=7¹⁴

b) 2⁷+⁶+⁸+²-⁷-⁵-⁹

=2²
