Just multiply like normal and carry over
Answer:
Step-by-step explanation:
(x - 1) × ( cancel the factor (x - 1) on numerator and denominator
= 1
[ In the same way 2 × 
= 1 ]
The required rational expression is
Answer:
∠A= 45°....
Step-by-step explanation:
To find ∠A first we have to find the length of side B by cosine law:
b^2 = a^2 + c^2 – 2 a c cos B
b^2=(2)^2 +(√3 + 1)^2 - 2(2)(√3 + 1) cos 60
b^2 = 6
Taking square root at both sides:
√b^2 = √6
b= 2.45
Now we can calculate ∠A by sine law:
b / sin B = a / sin A
2.45 / sin 60 = 2 / sin A
sin A= 2* √3/2 /2.45
sin A = 2√3/2 * 1/2.45
sinA = 2√3/ 4.9
sin A = 0.7069
sin A = 0.707
A=45°
Thus ∠A= 45°....
63 - 2.95 = 60.05
Rounding using significative figures
63 has three significative figures
2.95 has three
So, we must round the result to 2 significative figures.
Result = 60
Answer:
<h2><em><u>
0.6 = 6/10 = 3/5 is the answer.</u></em></h2>
Step-by-step explanation:
0.6 = 6/10 = 3/5
is the answer
This is because you have to substitute.
Given:
x = 3
y = -1
Unknown:
Final Answer
(x*y^2)/5
((3)(-1*-1)/5
= (3*1)/5
<h2><em><u>
= 3/5</u></em></h2><h2><em><u>
= 6/10</u></em></h2><h2><em><u>
= 0.6</u></em></h2><h2><em><u>
</u></em></h2>
Hope this helped,
