Lourenço analyzed prices of laptop

1 answer:

4 0

The price y is a function of x, the speed of the processor.

In function notation this means, y=f(x), where f(x)=<span>101x + 207.85.

For example to calculate the (approximate) price of a laptop with processor 4 gigahertz, we let x=4, and plug in f.

That is the price y for x=4 is calculated by y=f(4).

So, since y=f(x)=<span>101x + 207.85, the (expected) price of a laptop with processor speed 2.5 gigahertz is :

y=f(2.5)=101(2.5)+207.85= 460.35 ($)

In the diagram below of triangle UVW, X is a midpoint of UV and Y is a midpoint

NeTakaya

Step-by-step explanation:

Given: X is midpoint of UV and Y is midpoint of VW.

$\therefore XY || UW$

(By mid-point theorem)

$\therefore \angle XYV \cong \angle UWY\\.. (corresponding\: \angle 's) \\\therefore m\angle XYV = m\angle UWY\\\therefore 98 - 6x = 63- x\\\therefore 98 - 63= 6x- x\\\therefore 35= 5x\\\\\therefore x = \frac{35}{5}\\\\\huge \orange {\boxed {\therefore x = 7}} \\\\m\angle UWY = (63 - x) °\\\\\therefore m\angle UWY = (63 - 7) °\\\\\huge \purple {\boxed {\therefore m\angle UWY = 56 °}}$
