Hello :
hello :
the nth term is : An=A1×r^(n-1)
<span>The first term of the sequence is 0.01
r =An/an-1 =20
</span><span>An =0.01(20)^n-1...(answer :D )

What is the length of AC?

Otrada [13]

Answer:

Length of AC = <u>12units</u>.

Step-by-step explanation:

$\sf\large{\star Given:-}$

Hypotenuse of the triangle = $\sf\pink{10\:units.}$
Height of the triangle = $\sf\pink{8 \: units.}$

$\sf\large{\star To\: Find:-}$

$\rightarrow$ Base of the triangle.

$\sf\large{\star Solution:-}$

$\rightarrow$ As we know that,

Pythagoras Theorem:

$\sf\blue{Hypotenuse^2\:=\: Height^2+Base^2}$

So, In triangle ABD by putting the value of hypotenuse and height in this formula we get,

$\rightarrow$ $\sf{10^2\:=\: 8^2 + Base^2}$

$\rightarrow$ $\sf{100\:=\: 64 + Base^2}$

$\rightarrow$ $\sf{100-64\:=\: Base^2}$

$\rightarrow$ $\sf{36\:=\: Base^2}$

$\rightarrow$ $\sf{\sqrt{36}\:=\: Base}$

$\rightarrow$ $\sf{6\:=\: Base}$

Since, it is given that BD is the perpendicular bisector of AC so length of AC will be doubled.

Therefore, length of AC of the given triangle = $\sf\purple{12units.}$

Jayden works for Float like a butterfly sting like a bee boxing club and received 660 on his last paycheck. If he gets paid time

alexandr402 [8]

Answer:

He make an hour if he worked 50 hours= 275

Step-by-step explanation:

Jayden worked for Float like a butterfly sting like a bee boxing club and received 660 on his last paycheck. Suppose he gets paid time and a half for overtime. How much does he make an hour if he worked 50 hours?

Sol: Jayden received on his last paycheck = 660

Half for over time = 660/2 = 330

Paid time = 660 - 330 = 330

In 50 hours he makes = 330 x 50 = 16500

In one hour he makes = 16500/60 ( 1 hour = 60 min)

= 275

2. JI. has coordinates J(-6, 1) and Z(-4, 3). Find the coordinates of the midpoint.

AleksandrR [38]

Answer:

(- 5, 2 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( $\frac{x_{1}+x_{2} }{2}$ , $\frac{y_{1}+y_{2} }{2}$ )

Here (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (- 4, 3) thus

midpoint = $\frac{-6-4}{2}$ , $\frac{1+3}{2}$ ) = ( $\frac{-10}{2}$ , $\frac{4}{2}$ ) = (- 5, 2 )
