(x+1)² + (y-1)²=64

(x+1)² + (y-1)²=8²

(x-h)² + (y-k)² = r²

Shkiper50 [21]

Answer:

Step-by-step explanation:

H(3,2) & J(4, 1)

$Slope = \dfrac{y_{2} -y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{1-2}{4-3}\\\\\\=\dfrac{-1}{1}\\\\= -1$

K(-2,-4) & M(-1 , -5)

$Slope =\dfrac{-5-[-4]}{-1-[-2]}\\\\=\dfrac{-5+4}{-1+2}\\\\= \dfrac{-1}{1}\\\\\\= -1$

Line HJ and KM have same slopes. So, they are parallel

Answer:

[45tan(82°)+123] meters

A is correct

Step-by-step explanation:

You are standing 45 meters from the base of the Empire State Building.

You estimate that the angle of elevation to the top of the 86th floor(the observatory) is 82°.

If the total height of the building is another 123 meters above the 86th floor.

OB = 45 m , ∠O= 82°

In Δ OBA, ∠B = 90°

$\tan82^\circ=\dfrac{AB}{OB}$

$\tan82^\circ=\dfrac{AB}{45}$

$AB=45\tan82^\circ$

Top of the building, T at 123 m from A

Total height of building = BA + AT

$=45\tan82^\circ+123\text{ meters}$

Hence, The height of building from ground is [45tan82°+123] meters

What is the volume, in cubic cm, of a rectangular prism with a height of 10cm, a width of 20cm, and a length of 11cm??

Alex787 [66]

here's the solution,

=》volume = l × b × h

where,

l = lenght
b = width
h = height

so,

=》

$v = 11 \times 20 \times 10$

=》

$2200$

so, volume = 2200 cm³
