which equation represents the geometric sequence? 3, 9, 27, 81,... A. next=now •3 B. now=next •3 C. next=now • (1/3) D. now=next

9966 [12]

Answer:

answer A. next=now •3

Step-by-step explanation:

Looking at the sequence 3, 9, 27, 81, you "see" a that each next number is formed by multiplying the current

number by 3. This is exactly what is stated in answer A. next=now •3

EXTRA:

Mathematically, the function llooks ike f(x) = 3"

Two joggers start from opposite ends of an 8 mile course running towards each other. One jogger is running at a rate of 4 mph. T

Licemer1 [7]

Answer:

48 minutes

Step-by-step explanation:

Given: The distance between A and B is 8 miles. Speed of one jogger is 4 miles per hour, and speed of other jogger is 6 miles per hour.

To find: After how many minutes will the joggers meet, if they are running towards each other.

Solution:

Let both the joggers will meet after t hours, at point P between A and B.

We know that $Distance=speed\times time$

Let the jogger running at a speed of 4 miles per hour starts from point A.

So,

$AP=speed\times time$

$AP=4\times t$

$AP=4t$

Let the jogger running at a speed of 6 miles per hour starts from point B.

So,

$BP=speed\times time$

$BP=6\times t$

$BP=6t$

We have,

$AP+BP=AB$

$\implies4t+6t=8$

$\implies10t=8$

$\implies t=\frac{8}{10}$

$\implies t=0.8$

So, both the joggers will meet after 0.8 hours or $0.8\times60=48$ minutes.

Hence, the joggers will meet after 48 minutes.

11th grade geometry:

Aliun [14]

Answer:

<em>The perimeter is 72 units and the area is 149 square units.</em>

Step-by-step explanation:

$\triangle SBA$ has coordinates $S(15,-8),B(-2,21)$ and $A(0,0)$

Using the distance formula.........

Length of side $SB = \sqrt{(15+2)^2+(-8-21)^2}= \sqrt{17^2+(-29)^2}= \sqrt{1130}$

Length of side $BA= \sqrt{(-2)^2+(21)^2}= \sqrt{445}$

Length of side $AS =\sqrt{(15)^2+(-8)^2}=\sqrt{289}=17$

So, the perimeter of the triangle will be: $(SB+BA+AS)= \sqrt{1130}+ \sqrt{445}+17 =71.71... \approx 72$ units. <em>(Rounded to the nearest unit)</em>

The height of the triangle for the corresponding base $SB$ is 8.89 units.

<u>Formula for the Area of triangle</u>, $A= \frac{1}{2}(base\times height)$

So, the area of the $\triangle SBA$ will be: $\frac{1}{2}(\sqrt{1130}\times 8.89)= 149.42... \approx 149$ square units. <em>(Rounded to the nearest unit)</em>
