Prove that 3 power p + 1 - 3 power P upon 2 multiply 3 power p is equal to 1 ​
Anit [1.1K]

Answer:

see explanation

Step-by-step explanation:

note that 3^{p+1} = 3^{p} × 3 ( when multiplying exponents are added )

Given

\frac{3^{p+1}-3^{p}  }{2.3^{p} } ← factor out 3^{p} on numerator

= \frac{3^{p}(3-1) }{2.3^{p} }

= \frac{2.3^{p} }{2.3^{p} }

= 1

Answer plss. will mark the first correct answer as brainliest!!
Eva8 [605]

Answer:

(-1,-2, -3, -4)

Step-by-step explanation:

-15 < 3n <6

-15 < 3 (-1,-2, -3, -4) <6

3 • -1 = -3

3 • -2 = -6

3 • -3= - 9

3 • -4 = -12

so all these answer still make -15 the lowest value and 6 the highest value.

Given the relation x = y 4 − 9 y 2, identify the x- and y- axis intercepts.
Svetlanka [38]

The x-intercepts are (0,0)

The y-intercepts are (0,0),(0,3),(0,-3)

Explanation:

The relation is x=y^{4} -9y^{2}

To find the x-intercept, let us substitute y=0 in the equation x=y^{4} -9y^{2}, we get,

x=(0)^{4} -9(0)^{2} \\x=0

Thus, the x-intercepts are (0,0)

To find the y-intercept, let us substitute x=0 in the equation x=y^{4} -9y^{2}, we get,

0=y^{4}-9 y^{2}

let us switch sides and solving, we get,

\begin{aligned}y^{4}-9 y^{2} &=0 \\y^{2}\left(y^{2}-9\right) &=0 \\y^{2} &=0, y^{2}-9=0\end{aligned}

Taking square root,

y=0 and \begin{aligned}y^{2}-9 &=0 \\y^{2} &=9 \\y &=\pm 3\end{aligned}

Thus, the y-intercepts are (0,0),(0,3),(0,-3)
