If a paper is 4/1000 inches think, how many of them will it take to equal 1000?
Well... if we take 1000 divided by 4 we get 250.
So 250 sheets of paper would be 1 inch thick...
Answer:
For 2a, we are completing the square (see the image below)
To find the stationary point (2b) you change the sign of the number inside the brackets and keep the number outside the same i.e (-2, 7)
Hope this helps!
Yes, unless you are solving an equation with two negatives.
Answer:
x is 46.67
y is 28.4°
Step-by-step explanation:
To solve for x we use sine
sin ∅ = opposite / hypotenuse
AC is the opposite
x is the hypotenuse
so we have
sin 59° = 40 / x
x sin 59 = 40
Divide both sides by sin 59
x = 40/sin 59
x = 46.67
To solve for y we also use sine
sin y = 30/ 63
y = sin^-1(30/63)
y = 28.4°
Hope this helps you
