Answer:

Step-by-step explanation:
Two points are given to us and we need to find the slope of the line that passes through these two points . The two points are (-2,-3) and (5,4) .As we know that the slope of the line is given by
<u>Slope </u><u>of </u><u>a </u><u>line </u><u>is </u><u>:</u><u>-</u>

On using this formula we can find the slope of the line .
<u>Putting</u><u> the</u><u> </u><u>respective</u><u> values</u><u> </u><u>:</u><u>-</u>
The value of a2+b2 = 0.05
The value of a3+b3 = 41.73
Concept: (a+b)2 = a2+b2+2ab
(a-b)2 = a2+b2-2ab
(a+b)3 = a3+b3+3a2b+3ab2
(a-b)3 = a3-b3-3a2b+3ab2
(I) a²+b²=(1/7-4✓3)²+(1/7+4✓3)²
⇒ ( 1/49 - 48) +(1/49 + 48)=(1-2352/49) + (1+2353/49)
⇒ -47.97 +48.02= 0.05
(ii) a³+b³=(1/7-4✓3)³+(1/7+4✓3)³
⇒(-6.78)³ +(7.07)³
⇒-311.66 +353.39= 41.73

y= 3/8 OR 0.375
Step-by-step explanation:
yes
I=20 amps.
By the way, did you know that this is Ohm's Law?
2+6+18+54+162+486+1458+4375=6561
you multiply the previous number by three to find the next value
