Answer:

As a column vector 3a +b = (9,10)

Step-by-step explanation:

A =

(2

4)

b =

(3

-2)

3a = 3*2 = 6

3*4= 12

3a + b = 6. + 3

Tamiku [17]

Step-by-step explanation:

Since ,

Money lended =$400

Intetest =27.74%

Therefore,

Intetrst=p×r×t/100,if interested monthly

=400×27.74×1/100(interested monthly)

=4×27.74

=$110.96

Interest=p×r×t/100×1/12,if interested anually

=400×27.74×1/100/12

=110.96/12

=$9.24 or it will be $110.96 if it is interested anuaaly..

I have been stuck on this question for a while. I need to find the area of the shaded region and round to the nearest tenth.
ZanzabumX [31]
<h3>Answer:</h3>

818.4 in²

<h3>Step-by-step explanation:</h3>

The area of a circular sector is given by ...

... A = (1/2)r²·θ . . . . . θ in radians

The area of the isosceles triangle with apex angle 150° is given by ...

... A = (1/2)r²·sin(θ)

Then the area of the shaded segment is ...

... A = (1/2)r²·(θ - sin(θ))

... A = (1/2)·(27.8 in)²(5π/6 -sin(5π/6)) ≈ 818.4 in²

_____

If you (erroneously) use 3.14 for π, you get 817.9 in². Some answer keys expect you to use that value, even though it does not have sufficient accuracy for this problem.
