The equivalent expression of (a⁻⁷ . b⁻²)⁻⁹ is a⁶³b¹⁸

How to find equivalent expression?

using the law of indices,

[tex](a^{x}) ^{y} = a^{x X y} =a^{xy}[/tex]

Therefore, we multiply the inner exponent by the outer exponent.

(a⁻⁷ . b⁻²)⁻⁹ = a⁻⁷ ˣ ⁻⁹ b⁻² ˣ ⁻ ⁹

a⁻⁷ ˣ ⁻⁹ b⁻² ˣ ⁻ ⁹ = a⁶³b¹⁸

Therefore,

(a⁻⁷ . b⁻²)⁻⁹ =  a⁶³b¹⁸

Answer:

B.The rate of change of function A is 2.

The rate of change of function B is 2.

Rate of function A: 2 (coefficient for x)

Rate of function B: 2, because an increment of 1 in x (e.g. 3 to 4) yields an increment of 2 in y (3 to 5)

The number of student athletes at a high school is 475 and is increasing at a rate of 4.8% per year. Use an exponential function to find the number of student athletes after 9 years.

please show your work!!!

Answers

Answer:

475 × 1.48^9 or 16182

Step-by-step explanation:

We start with 475. Then to find the number of students after 1 year we mult 475 by 1.48 (48% + 1 because we're increasing in students). But, to get it after 9 years, we raise that 1.48 to the power of 9 which is equal to 1.48 * 1.48 * 1.48 and so on 9 times. This leads us to our final equation of 475 * 1.48^9 or roughly 16,182

Step-by-step explanation:

2% of 100 is 2 then you do 2x2 for 4

Answer:

$104

Step-by-step explanation:

Compound interest is an interest on an interest. By that I mean you have $8 and 50% interest. 50% of 8 is 4, so 8+4=12. Then add on another 50%, half of 12 is 6. So 12+6 is 18, and so on.

Andrea has $100. 2% interest not compunded.

2% of 100 is 2.

So, 100+2 is 102.

Since it's not compounded, we just add another $2.

100+2+2=$104

Everybody has been love-struck at some point in life. In The Song of Wandering Aengus, William Butler Yeats experienced love at second sight. When he sees her, she is a fish. Then, she turns into a beautiful girl. The poem dwells on magic of love, and how attracted people get when they meet the glimmering someone. The poems theme is unreturned love. From the first two lines of the poem, the speaker doesnt feel well. I went out to the hazel wood,/Because a fire was in my head. The imagery of fire shapes the mood of love he wants in his life. Of course his head is not literally on fire, fire represents his desire that takes him into the hazel wood. Aengus shapes a wand, or a stick for fishing. He uses a berry as the bait to catch fish. The moth-like stars were flickering out, so you know that the time of the day is dawn. When Aengus dropped a berry in the stream, he caught a small silver fish.In the second stanza, Aengus describes laying the fish on the floor, and starting the fire. He was starting to cook something and something rustles on the floor and someone calls his name. When he turns around and expects to see the trout he sees a glimmering girl, who had apple blossom hair and she called him by his name again and then ran faded through the brightening air.The third stanza jumps forward until Aengus is an old man, and spends his whole life looking for the glimmering girl. In the second line of the third stanza, Aengus looks Through hollow lands and hilly lands he imagines he will find her and kiss and take her hand. He also puts that he and she will walk among grass together, and they will pluck the silver apples of the moon and the golden apples of the sun until the end of time. In the end, W B Yeats, poem is about the fire of love and passion. In the first two stanza Yeats is not feeling well and he meets a girl of his life. The poem starts he going to do clear his head and goes to fish, and then the the trout turn into his love and she calls his name and fades through the brightening air. The poem tells readers that if someone love someone they would do whatever it takes to find their love for them. Can some one help me please
