Cost A=0.6489 take the inverse cosine of both sides

Mathematics

Stolb23 [73]3 years ago

I am not quite sure what the question asks for,
But this is what i assume it wants:

Cos A= 0.6489
In this given one, we basically find the size of the angle A
we do cosine inverse on both sides to get the size of the angle A
cos^{-1} : It looks like this in the calculator
cos^{-1} × cos A=cos^{-1}(0.6489)
(cos^{-1} and cos cancels out)
A=cos^{-1}(0.6489)
A=49.54°
check: 
cos 49.54=0.6489 (its right!)

Evaluate the polynomial when a.x=0 and b.x=-1<br> x2 – 3x - 7
Arlecino [84]

Answer:

a) -7 & b) -6

Step-by-step explanation:

Here,

a) x = 0

Solution ↦

x2 - 3x - 7 \\  =  0 \times 2 - 3 \times 0 - 7 \\  =  - 7

b) x = -1

Solution ↦

x2 - 3x - 7 \\  =  - 1 \times 2 - 3 \times ( - 1) - 7 \\  =  - 2 + 3 - 7 \\  =  - 9 + 3 \\  =  - 6
