Answer:
the direction that should be walked by Ricardo to go directly to Jane is 23.52 m, 24° east of south
Explanation:
given information:
Ricardo walks 27.0 m in a direction 60.0 ∘ west of north, thus
A= 27
Ax = 27 sin 60 = - 23.4
Ay = 27 cos 60 = 13.5
Jane walks 16.0 m in a direction 30.0 ∘ south of west, so
B = 16
Bx = 16 cos 30 = -13.9
By = 16 sin 30 = -8
the direction that should be walked by Ricardo to go directly to Jane
R = √A²+B² - (2ABcos60)
= √27²+16² - (2(27)(16)(cos 60))
= 23.52 m
now we can use the sines law to find the angle
tan θ = 
= By - Ay/Bx -Ax
= (-8 - 13.5)/(-13.9 - (-23.4))
θ = 90 - (-8 - 13.5)/(-13.9 - (-23.4))
= 24° east of south
<u>Answer:</u>
<em>Due to the shortcomings in Piaget’s approach to cognitive development several other theories were put forward.</em>
<u>Explanation:</u>
Jean Piaget is the psychologist that offered explanations about cognitive development in children. There were several shortcomings in his theories and thus alternative theories about cognitive <em>development in children </em>were developed.
<em>Lev Vygotsky</em> proposed another explanation to children’s cognitive development. He strongly emphasized on the influence of culture on <em>children’s cognitive development</em>. He believes that it is through socio-cultural interactions development progresses.
He believed that individualized thoughts begin after these interactions. He take on <em>self-speech </em> was different from Piaget. Vygotsky considered self-speech as a guide to thinking while Piaget thought <em>self-speech to be egocentric. </em>
