Answer:

To solve this exercise i'll graph a plot of the room:

The diagnol of the floor of the room divides it into two right triangles, were the length of the walls represents the base and height and the dignol is the hypothenuse.

Usinf Phyagoras Theorem, that states that the square of the hypothenuse is equal to the right triangle. we can calculate the heightof thr triangle as:

Triangle RST has the vertices R(2, 3), S(-2, 1), and T(-1, 5). What are the coordinates after the two transformations: Reflectio

SCORPION-xisa [38]

Answer:

R''(2,-3), S''(-2,-1) and T'(-1,-5).

Step-by-step explanation:

The given vertices of triangle are R(2, 3), S(-2, 1), and T(-1, 5).

Reflection over the y-axis:

$(x,y)\to (-x,y)$

Using this rule, the vertices after reflection are

$R(2,3)\to R'(-2,3)$

$S(-2,1)\to S'(2,1)$

$T(-1,5)\to T'(1,5)$

Rotation at 180 degrees around the origin.

$(x,y)\to (-x,-y)$

Using this rule, the vertices after reflection are

$R'(-2,3)\to R''(2,-3)$

$S'(2,1)\to S''(-2,-1)$

$T'(1,5)\to T''(-1,-5)$

Therefore, the coordinates of vertices after the two transformations are R''(2,-3), S''(-2,-1) and T'(-1,-5).

amid [387]

Answer:

Paedtricians claim isn't true.

Step-by-step explanation:

The hypothesis :

H0 : σ = 7

H0 : σ > 7

The test statistic ; χ² :

χ² = [(n - 1) * s²] ÷ σ²

n = 25 ; s = 4.3, σ = 7

χ² = [(25 - 1) * 4.3²] ÷ 7²

χ² = [(24 * 4.3²] ÷ 49

χ² = 443.76 / 49

χ² = 9.056

At α = 0.01 ; critical value = 42.980

Since critical value > test statistic, we fail to reject the null, H0.

A car was originally purchased in January 2010 for 27000 dollars. The car depreciates at a rate of 18% every year.

Maksim231197 [3]

Answer:

Number of year(n) = 3.4 year (Approx)

Step-by-step explanation:

Given:

Purchase value of car = $27,000

Depreciation rate per year (d) = 18% = 0.18

Future price = half of its original value = $27,000 / 2 = $13,500

Find:

Number of year(n) = ?

Computation:

$Future price =Purchase value(1-d)^n\\\\13,500=27,000(1-0.18)^n\\\\0.5=(0.82)^n\\\\n=3.444(Approx)$

Number of year(n) = 3.4 year (Approx)
