Louis ran 12 laps

Step-by-step explanation:

The ratio of the number laps Moses ran to the number laps Louis ran was 2 to three.

Find the sum of a finite geometric sequence from n = 1 to n = 7, using the expression −4(6)n − 1.

Verizon [17]

Answer:

Step-by-step explanation:

The formula of a sum of terms of a gometric sequence:

$S_n=a_1\cdot\dfrac{1-r^n}{1-r}$

a₁ - first term

r - common ratio

We have

$a_n=-4(6)^{n-1}$

Calculate a₁. Put n = 1:

$a_1=-4(6)^{1-1}=-4(6)^0=-4(1)=-4$

Calculate the common ratio:

$r=\dfrac{a_{n+1}}{a_n}\\\\a_{n+1}=-4(6)^{n+1-1}=-4(6)^n\\\\r=\dfrac{-4(6)^n}{-4(6)^{n-1}}=6^n:6^{n-1}\\\\\text{use}\ a^n:a^m=a^{n-m}\\\\r=6^{n-(n-1)}=6^{n-n+1}=6^1=6$

$\text{Substitute}\ a_1=-4,\ n=7,\ r=6:\\\\S_7=-4\cdot\dfrac{1-6^7}{1-6}=-4\cdot\dfrac{1-279936}{-5}=-4\cdot\dfrac{-279935}{-5}=(-4)(55987)\\\\S_7=-223948$

I need help on both, I don’t understand. It’s dealing with similar triangles

11111nata11111 [884]

Answer:

11. MN = 4 m

12. LK = 8 m

Step-by-step explanation:

11. Apply pythagorean theorem to find MN:

MN = √(5² - 3²) = √(25 - 9) = √16

MN = 4 m

12. Recall: The ratio of the corresponding side lengths of any two given similar triangles are equal.

MN corresponds to LK

MO corresponds to KO

Therefore:

LK/MN = KO/MO

LK/4 = 10/5

LK/4 = 2

Multiply both sides by 4

LK = 2*4

LK = 8 m
