110- у 70- y = [ ? ]°

Mathematics
1 answer:
pickupchik [31]3 years ago
8 0

Answer:

y = 90°

Step-by-step explanation:

y + x = 110° because the sum of two interior angles is equal to an interior angle

x + 70° = y ➡ y - x = 70°

y + x = 110°

y - x = 70° add two equations

2y = 180° (x eliminated -x)

y = 90°

State the chain rule for the derivative dy/dt if y(t)=f(u(t))(chain of f and u)
Ann [662]

Answer:

\displaystyle\frac{d(y(t))}{dt} =\displaystyle\frac{d(f(u(t)))}{dt} = f'(u(t)).u'(t)

Step-by-step explanation:

The chain rule helps us to differentiate functions and a composition of two functions.

Let r(u) and s(u) be two function. Then, composition of these two functions can be be differentiated with the help of chain rule. It states that:

\displaystyle\frac{d(r(s(u)))}{du} = r'(g(u)).s'(u)

Now, we are given

y(t) = f(u(t))

Then, by chain rule, we have:

\displaystyle\frac{d(y(t))}{dt} =\displaystyle\frac{d(f(u(t)))}{dt} = f'(u(t)).u'(t)

A coat of paint of thickness 0.06 cm is to be applied uniformly to the faces of a cube of edge 33 cm. Use differentials to find
Aneli [31]

Answer:

392 cm^3

Step-by-step explanation:

Let X represent the edge of a cube

let t represent the thickness of the paint.

Volume of a cube = x^3

V = x^3

Differentiate V with respect to x

dV/dx = 3x^2

dV = 3x^2 dx

dx = 2dt

= 2(0.06)

= 0.12

dV = 3(33)^2 (0.12)

dV = 392.04cm^3

dV = 392 cm^3

Whats the reason for 8x-5-2x=2x+1-2x
Irina-Kira [14]
Your answer is X= -1
you have to move terms first to get this
8x-5=2x+1
then collect like terms and calculate sum
8x-2x=1+5
lastly you divide both sides by 6
X=1
HOPE THIS HELPS! :)
