How do you Identify and contrast the differences between the rise in prices due to inflation and the rise in prices in microecon

andrezito [222]

One can Identify the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets by?

Observing the trends in prices.
Observing Demand and supply curve.

<h3>Contrast the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets.</h3>

The difference that exist between a rise in price due to the inflation and a rise in price due to microeconomic markets is based on the price changes that has occurred in terms of demand and supply model.

Note that this is said to be the price in a given market but the price rise as a result of to inflation tells that the price rise is one that reaches a lot of markets and not only just one market.

Hence, One can Identify the differences between the rise in prices due to inflation and the rise in prices in microeconomic markets by?

Observing the trends in prices.
Observing Demand and supply curve.

How many distinct positive integer-valued solutions exist to the equation (x2 - 7x + 11)(x2 - 13x + 42) = 1

Anna35 [415]

Answer:

The given equation has TWO positive integer valued solutions, {6, 7}

Step-by-step explanation:

Here we are given two trinomial factors, each of which needs to be set equal to zero and in each case the resulting quadratic equation solved.

(x^2 - 7x + 11) has the coefficients {1, -7, 11}, and so the discriminant of this quadratic is b^2 - 4(a)(c), or 49 - 4(11), or 5.

Because this discriminant is positive, we know immediately that this quadratic has two real, unequal roots involving √5 (NO integer roots).

Next we focus on (x^2 - 13x + 42). The discriminant is b^2 - 4(a)(c), or

169 - 168, or 1. Again we see that there are two real, unequal roots:

+13 ± √1 +13 ± 1

x = --------------- or x = -------------

2 2

OR x = 14/2 = 7 (integer) or x = 12/2 = 6 (integer).

The given equation has TWO positive integer valued solutions, {6, 7}

the size of a rectangular computer screen is determined by the length of its diagonal. tom buys a 52cm screen that is 33 cm high

marta [7]

Answer:

40.20cm approx

Step-by-step explanation:

Step one

given data

We are told that the dimension of a computer screen

diagonal= 52 cm

height= 33cm

Length = ?

Required

The length of the base of the screen

Step two

Let us use Pythagoras theorem to find the length of the base

Hyp^2= Opp^2+ Adj^2

52^2= 33^2+ L^2

2704= 1089+L^2

L^2= 2704-1089

L^2= 1615

L=√1615

L= 40.20cm approx

<u>The length is 40.20cm approx.</u>

a water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area f

andrew11 [14]

Answer:

11 feet

Step-by-step explanation:

Area formed by the watery pattern is 379.94 square feet.

Since the water is being sent out in circular pattern, the maximum distance at which the water is reaching out will be equal to the radius of the circle as the sprinkler is at the center of the circle.

Area of a circle is given as:

$Area=\pi r^{2}\\\\ 379.94 = \pi r^{2}\\\\r^{2}=\frac{379.94}{\pi}\\\\ \text{Using pi equal to 3.14, we get}\\\\ r^{2}=121\\\\ r = 11$

This means the radius of the circular pattern being formed is 11 feet. So the sprinkler can spread the water 11 feet away from it.
