Answer:

Interest at the end of the first year is $105.93

Step-by-step explanation:

$800 at 12.5% APR compounded monthly.

Interest at the end of the year

= $800 *( (1+0.125/12)^12 - 1 )

= $800 * 0.132416

= $105.93

Prove that x=2 if 4^x=8x...where ^ stands for "to the power of".
Romashka [77]
In order to prove this, you simply plug in the number 2 everywhere you see X:

4^(2) = 8(2). 

Simplify

16 = 16 √

Since this checks out, x is proven to be 2.

2. IQS = 4 and QR is a perpendicular bisector of TS , determined which of the following claims is true
Pavel [41]

Answer:

RS=5 TRUE

RS=4 FALSE (it’s 5)

ST=10 FALSE (it’s 8)

QR=4 FALSE (its 3)

Step-by-step explanation:

First, we have to determine the sides of the triangle.

4x-3=2x+1

4x-2x=1+3

2x=4

x=2

SO, RS=4x-3=4(2)-3=8-3=5

RT=2(x)+1=2(2)+1=5

QR=4²+b²=5².    16+b²=25.    b²=25-16.    b²=9.     b=3

CLAIMS:

RS=5 TRUE

RS=4 FALSE (it’s 5)

ST=10 FALSE (it’s 8)

QR=4 FALSE (its 3)

MNOP is a trapezoid with a meadian QR. Find x.
mamaluj [8]

Answer:

D. x = 8

Step-by-step explanation:

MNOP is a trapezoid with a meadian QR

So

QR = 1/2(NO + MP)

2(QR) = NO + MP

2(16) = 8 + 2x + 8

32 = 2x + 16

2x = 16

 x = 8
