Answer:

5(–9a–1)+7=0

5(-9a-1)=-7

-9a-1=-7/5

9a+1=7/5

9a=7/5 +1

a=(7+5)/(5×9)=35/45=7/9

Oksanka [162]
Divide by x then is becomes p/x = 4-k
subtracte 4 which makes it -k=p/x -4

given the first term and the common difference of an arithmetic sequence find the 52nd term and the explicit formula. did I do t
Andreyy89

Answer:

41)  A52 = -10206

42) - 320

43)  -276

44)  10200

Step-by-step explanation:

41) A1 = -6, D = -200

An = a1 + (n - 1) d

We have to use the above formula to find the 52nd term.

A52 = -6 + (52 - 1) -200

= -6 + 51*-200

= -6 - 10200

A52 = -10206


42)

37 + -7(52 -1)

37 + -7(51)

= 37 - 357

= - 320

43)

30 + -6(52 -1 )

= 30 + -6(51)

= 30 - 306

= -276

44)

0 + 200(52 -1)

= 200(51)

= 10200

Thank you.

Hope you will understand the concept.

Thank you.

A right triangle as shown below
anastassius [24]

Answer:

sin a = 7/25

cos a = 24/25

tan a = 7/24

Step-by-step explanation:

Trig. How wonderful. I get tripped up on these types of problems some times, so I decided to try to help! To start, write out the three ratios.

SOH (sine=opposite/hypotenuse) CAH (cosine=adjacent/hypotenuse) TOA (tangent=opposite/adjacent)

Then, label the triangle with “hypotenuse” “adjacent” and “opposite.” This helps us correctly use and find the raitos. Then, use these ratios to find out the ratios of A!

sin a = 7/25

cos a = 24/25

tan a = 7/24

If needed, just divide the ratios to get their decimal form!

What is 19% of 72? I NEED TO KNOW HOW YOU GOT THE ANSWER TO!!
irinina [24]
First you must multiply the number by the percent. (19*27= 513)
Then you divide the answer by 100, or move decimal two places to the left. (513/100= 5.13)
Then round to the nearest whole number (5.13 is approximately 5)
Therefore 19%of 27 = 5
