Dùng phương pháp bình phương bé nhất để tìm các hệ số a, b sao cho hàm số

y = a sin x + b x căn (x+1)
xỉ tốt nhất của bảng số liệu sau
x 0.2 1.3 2.8 n
2 + 1
y 1.2 m + 1 3.1

i think that you should ask google for the answer to that problem because if we don't know it google does

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .
