According the quotient of powers property, when you have the division of two powers with the same base, then you must subtract the exponents.

Therefore, keeping the property above on mind, you have that the quotient is the shown below:

\frac{(-7)^2}{(-7)^{-1}}=(-7)^{(2-(-1))}=(-7)^{(2+1)}=(-7)^3=-343

The equation for a circle is ​x^2 − 8x + y^2 - 2y - 8 = 0
Ivanshal [37]

Answer:

B

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

To obtain this form use the method of completing the square

Given

x² - 8x + y² - 2y - 8 = 0 ( add 8 to both sides )

x² - 8x + y² - 2y = 8

add ( half the coefficient of the x/y terms )² to both sides

x² + 2(- 4)x + 16 + y² + 2(- 1)y + 1 = 8 + 16 + 1

(x - 4)² + (y - 1)² = 25 → B

Plzzz help with all of the questions and plzZZZzZz show work I really need help I’m not understanding help with all the question
statuscvo [17]

Answer:

slope of EF=\frac{5}{3}  

∠QSR=45°,

∠PTQ=90°

if  RT=24

then SQ=48

square is always a rectangle

∠SUT=21°

Step-by-step explanation:

two line are perpendicular to each other if product of their slope equal to -1

m_{1}\times m_{2}=-1

slope of HE=m_1=-\frac{3}{5}

slope of EF=m_2

slope of EF=-1\frac{-5}{3}=\frac{5}{3}

slope of EF=\frac{5}{3}    answer

∠QSR=45°,

∠PTQ=90°

if  RT=24

then SQ=48

square is always a rectangle

given ∠SUT=3x+6

        ∠RUS=5x-4

∠SUT=∠RUS

3x+6=5x-4

x=5

∠SUT=3x+6=15+6=21°

∠SUT=21°
