Given two measurements, x and y, which both have uncertainty. Use the general error propagation formula, δf = vuut ∂f ∂xδx!2 + ∂

f ∂y δy!2 to derive the error propagation formulas, i.e. the expression for δf, for the following specific cases as found in the Taylor textbook. (a) Scaling by a constant: f = Cx where C is a constant with no uncertainty. (b) Addition: f = x + y (c) Multiplication: f = xy (d) Division: f = x y

If an object is bought for rupees 90 and then sold for a loss of 15% how much was it sold for​
Mashutka [201]

Answer:

76.50

Step-by-step explanation:

We are given the fact that you bought an object for 90 dollars, and in which you sold said object for a loss of 15%, we are then asked how much would that object be sold for.

To find the answer, we need to subtract the original amount by the percent loss, so :

90 - 15%

15% of 90 is 13.5, therefore :

90 - 13.5

76.5

Simplify the expression 2 (2 + 4y) + 3x.<br> PLS ANSWER ASAP DUE 9:20
Novay_Z [31]

Answer:

5x+8y

Step-by-step explanation:

We can first open the brackets by using the distrubitive propety.

2(x+4y)+3x

2x+8y+3x

Now we can combine like terms.

5x+8y.

I combined the 3x and the 2x. This works because imagined I have 3 of something then I got 2 more of that something I would now have 5 of that something.

Hoped this helped,

Ebony but a four year treasury note that pay the equivalent of 3.8% simple interest. She invested $3000 more in a 9 year bond e
Anastasy [175]

Treasury bond's invested amount is "$7000" and Bond's invested amount is "$10000",

Let,

  • The amount invested in treasury note will be = x
  • The amount invested in bond will be = (x + 3000)

then,

→ \frac{x\times 4\times 3.8}{100} +\frac{(3000+x)\times 9\times 4.6}{100}=5204

→       \frac{15.2x}{100}+\frac{(3000+x)\times 41.4}{100} =5204

→         \frac{15.2x}{100} +\frac{124200+41.4x}{100} =5204

→            \frac{15.2 x+124200+41.4x}{100} = 5204

→               56.6x+124200=520400

→                               56.6x=520400-124200

→                               56.6x=396200

→                                      x = \frac{396200}{56.6}

→                                         = 7000

Amount invested in bond will be:

= x+3000

= 7000+3000

= 10000    

Thus the above is the correct answer.

The gear ratio of two gears is the ratio of the number of teeth of the larger gear to the number of teeth of the smaller gear. I
VLD [36.1K]

Answer:

24 gear.

Step-by-step explanation:

It is given that Gear A:Gear B=Gear B:Gear C.

\dfrac{Gear A}{Gear B}=\dfrac{Gear B}{Gear C}

Gear A = 36 teeth

Gear C = 16 teeth

Let gear B have x teeth.

\dfrac{36}{x}=\dfrac{x}{16}

On cross multiplication we get

36\times 16=x\times x

576=x^2

Taking square root on both sides.

24=x

Therefore, gear B have 24 teeth.
