If (a²-1/a²)=23 find the value of i) (a+1/a), ii) (a³+1/a³)​<br><br>pls help me
vesna_86 [32]

Answer:

5

Step-by-step explanation:

(a + (1/a)2 =  a2 + (1/a2) + 2

⇒ (a + (1/a))2 = 23 + 2

⇒ (a + (1/a))2 = 25

⇒ a + (1/a) =

⇒ a + (1/a) = 5

a3+b3=

(a+b)

(a2−ab+b2)

where  a=a

and b=1/a.

so sum it up u get -1

Wes and Tma are a married couple and provide financial assistance to several persons during the current yeaL For the siruations
Gala2k [10]

Answer: Hello! Apparently, your question is incomplete since the rest of it is missing and we need the alternatives to work on. Fortunately, we were able to find the whole of it so we can help you! Here it goes:

Wes and Tina are a married couple and provide financial assistance to several persons during the current year. In all of the situations​ below, assume that any dependency tests not mentioned have been met.

Requirement

For each​ situation, determine whether the individuals qualify as Wes and​ Tina's dependents. ​(Select the best possible answer in each​ case.)

Requirement a. Brian is age 24 and Wes and​ Tina's son. He is a​ full-time student and lives in an apartment near campus. Wes and Tina provide over​ 50% of his support. Brian works as a waiter and earned​ $4,200.

Answer: He can't be considered a dependent because his income is higher than $4050. Also, he can't be considered a child since he is older than 23.

Requirement b. Same as Part a except that Brian is a​ part-time student.

Answer: The status of beig a student doesn't change the fact that he is over 23, so he is still not be claimed a dependent since he can't be considered a child.

Requirement c. Sherry is age 22 and Wes and​ Tina's daughter. She is a​ full-time student and lives in the college dormitory. Wes and Tina provide over​ 50% of her support. Sherry works​ part-time as a bookkeeper and earned​ $5,000.

Answer: She may be claimed as a dependent since she meets the four relationship requirements, age, abode and support. Also, being a student is not a strong influence in this case.

Requirement d. Same as Part c except that Sherry is a​ part-time student.

Answer: Under this condition, she can't be considered a dependent since she becomes an unqualified child. She's not a full-time student and over 18 years old.

Requirement e. ​Granny, age​ 82, is​ Tina's grandmother and lives with Wes and Tina. During the current​ year, Granny's only sources of income were her Social Security of​ $4,800 and interest on U.S. bonds of​ $4,500. Granny uses her income to pay for​ 40% of her total​ support, Wes and Tina provide the remainder of​ Granny's support.

Answer: Granny wouldn't be eligible, since her bonds are higher than $4050 , not considering her Social Security income.

Write the equation of the line perpendicular to y = x+ 5 that passes through the point ( -7,3).
Burka [1]

Answer:

y = - x - 4

Step-by-step explanation:

A line perpendicular to the line:  y = x + 5

must have a slope that is the "opposite of the reciprocal" of the slope of the given line. Then the slope of the perpendicular line must be "-1".

Now that we know the slope of the perpendicular line, we use the point (-7, 3) to complete the equation of the line:

y = -1 x + b

3 = -1 (-7) + b

then we solve for "b":

3 = 7 + b

3 - 7 = b

b = -4

Now we can write the total equation of the perpendicular line in slope-intercept form as:

y = - x - 4
