WILL GIVE BRAINLIES- ARITHMETIC SEQUENCE

BigorU [14]

Answer:

2,322,775

Step-by-step explanation:

$a_1=4\\\\a_i=a_{i-1}+11\\\\\implies a_2=a_{2-1}+11\\a_2= a_1+11 \\a_2= 4+11 \\a_2= 15\\\\d = a_2-a_1 \\d= 15-4 \\d= 11\\\\S_{650}=?\\\\\implies n = 650\\\\$

By the formula of sum of an Arithmetic Sequence

$S_n= \frac{n}{2} [2a_1+(n-1)d]\\\\S_{650}= \frac{650}{2} [2\times 4+(650-1)\times 11]\\\\S_{650}= 325 [8+649\times 11]\\\\S_{650}= 325 [8+7,139]\\\\S_{650}= 325\times 7,147\\\\\huge \red {\boxed {S_{650}=2,322,775}}$

In ΔBCD, the measure of ∠D=90°, the measure of ∠C=77°, and CD = 41 feet. Find the length of BC to the nearest foot.

Makovka662 [10]

Answer: $x\approx182\ ft$

Step-by-step explanation:

For this exercise you need to use the following Trigonometric Identity:

$cos\alpha =\frac{adjacent}{hypotenuse}$

Observe the Right triangle BCD given in the exercise. You can identify that, in this case:

$\alpha =\angle C=77\°\\\\adjacent=CD=41\ ft\\\\hypotenuse=BC=x$

Knowing these values, you can substitute them into $cos\alpha =\frac{adjacent}{hypotenuse}$ , as below:

$cos(77\°)=\frac{41}{BC}$

The next step is to solve for "x" in order to find its value:

$x*cos(77\°)=41\\\\x=\frac{41}{cos(77\°)}\\\\x=182.26\ ft$

Finally, rounded the result to the nearest foot, you get that this is:

$x\approx182\ ft$

We can calculate EEE, the amount of euros that has the same value as DDD U.S. Dollars, using the equation E=\dfrac{17}{20}DE= 20

Sphinxa [80]

Answer: 1 U.S.dollar = 0.85 euro.

1 euro = 1.18 dollars.

Step-by-step explanation:

The given equation: $E=\dfrac{17}{20}D$

, where 'E' is the amount of euros that has the same value as 'D' U.S. Dollars.

At D= 1,

$E=\dfrac{17}{20}=0.85\text{ euro}$

i.e. 1 U.S.dollar = 0.85 euro.

At E= 1 , we have

$1=\dfrac{17}{20}D\\\\\Rightarrow\ D= 20/17\approx1.18\text{ dollars}$

Hence, 1 euro = 1.18 dollars.
