Answer:

242 km

Step-by-step explanation:

distance = rate x time

so 165 km in 1.5 he is the same as 110 km per hour.

d = 110(2.2).

Answer:

1/2

Step-by-step explanation:

slope equals rise over run, so you go from your first point which is (0,0) and go up to (2,1), so you rise one and then go over 2, which gives you 1/2

Answer:

Part a) The rule of the sequence is $A(n)=50(0.52^{n-1})$

Part b) The height of the ball will be $13.52\ cm$

Step-by-step explanation:

Part a) Write a rule for the sequence using centimeters. The initial height is given by the term n = 1.

we know that

In a Geometric Sequence each term is found by multiplying the previous term by a constant called the common ratio (r)

In this problem we have a geometric sequence

Let

n-----> the number of path

a1 ----> is the initial height

r -----> the common ratio

we have

$a1=0.5\ m=0.5*100=50\ cm$

$r=52\%=52/100=0.52$

The rule for the sequence is equal to

$A(n)=a1(r^{n-1})$

substitute

$A(n)=50(0.52^{n-1})$

Part b) What height will the ball be at the top of the third path?

For n=3

substitute in the equation

$A(3)=50(0.52^{3-1})$

$A(3)=50(0.52^{2})$

$A(3)=13.52\ cm$

HELPP!!!! 100 points. Which expression is equivalent

devlian [24]

Answer:

$\Large \boxed{\sf A}$

Step-by-step explanation:

$\displaystyle 2x\sqrt{44x}-2\sqrt{11x^3}$

Let x = 2 because x > 0

$\displaystyle 2(2)\sqrt{44(2)}-2\sqrt{11(2)^3}=4\sqrt{22}$

See which expression is equal to 4√22 when x = 2

$2(2)\sqrt{11(2)}=4\sqrt{22}$

The expression is option A
