Answer:
just practice time and again practice might not make perfect but it surely makes better. relying when your teacher only might not help you must mostly rely on your hard work and also have people at your disposal to help you including the said teacher hope you'll improve
Step-by-step explanation:
this creates 2 similar triangles.
that means all angles are the same. and all the side lengths of one triangle correlate to the corresponding side lengths of the other triangle by the same multiplication factor.
her shadow is 23.05 - 18.9 = 4.15 m long.
the factor between the shadow lengths is then
4.15 × f = 23.05
f = 23.05 / 4.15 = 5.554216867...
the same factor now applies to the relation of the heights :
1.45 × 5.554216867... = 8.053614458... m
rounded the tree is 8.05 m tall.
Answer:
1/2
((-2)^2-(4*2)^1/3)/abs(-2*2)
-2^2 = 4
4*2 = 8
-2*2 = -4 and abs of that is 4
4-(8)^1/3/4
8^1/3 = 2
4-2 = 2
2/4 = 1/2
Step-by-step explanation:
Put y=0
-7/5x-0=7
x=7*-5/7=-5
x intercept=-5
put x=0
-0-4y=7
y=-7/4
y intercept =-7/4
