Cos90degrees cos30 degrees + sec-squared45degrees sin30degrees - cos270degrees sin180degrees

yawa3891 [41]

Step-by-step explanation:

$\cos 90 \cos 30 + \sec^2 45 \sin 30 - \cos 270 \sin 180$

But we know that

$\cos 90 = \cos 270 = \sin 180 = 0$

and

$\sin 30 = \dfrac{\sqrt{3}}{2} \:\:\text{and}\:\: \sec 45 = \sqrt{2}$

so this leaves us with just

$\sec^2 45 \sin 30 = (\sqrt{2})^2 \left(\dfrac{\sqrt{3}}{2} \right)= \sqrt{3}$

I have 10 bags of potatoes each containing 15 kg of potatoes. I want to make 50 small bags of potatoes each of the same mass . w

Alona [7]

Step-by-step explanation:

according to the given question

there are 10 bags each have 15kg potatoes so basically, we have 150 kg of poatoes

i want these potatoes to be equally distributed in 50 bags

therefore, mass of potato in 1 bag = total kg's of potatoes÷nuber of bags

mass of potato in 1 bag=150÷50 equals 3 kg

and so, each bag will have mass 3 kg

Complete the table using the equation y = 5x + 3.<br> x -1 0 1 2 3 <br> y -? ? ? ? ?

Simora [160]

Answer:

See below

Step-by-step explanation:

When x=-1, y=5(-1)+3=-5+3=-2

When x=0, y=5(0)+3=0+3=3

When x=1, y=5(1)+3=5+3=8

When x=2, y=5(2)+3=10+3=13

When x=3, y=5(3)+3=13+3=16

Therefore, this is the correct table:

x -1 0 1 2 3

y -2 3 8 3 16
