Answers

Answer 1

The value of (7²-√81) + √125) is 45

What are square root and square?

Squares are the numbers, generated after multiplying a value by itself. Whereas square root of a number is value which on getting multiplied by itself gives the original value. Hence, both are vice-versa methods. For example, the square of 2 is 4 and the square root of 4 is 2.Similarly, the square of 4 is 16 and the square root of 16 is 4.

A perfect square is a number, from a given number system, that can be expressed as the square of a number from the same number system. Therefore 4, 16, 25 are examples of perfect squares

7²-√81) + √125 is calculated as

49- 9+ 5 = 45

Therefore the value of 7²-√81) + √125 = 45

Is autonomous driving disruptive innovation? "Do you remember when I overwatered those mint plants?" Jilly asked Mrs. T."I used to think no one could kill a mint plant," Mrs. T. said, laughing."Well I am full of surprises, apparently," Jilly replied. Jilly remembered the sad green plants that just kept looking more and more wilted no matter how much water she gave them. It was a beginner's mistake, and Jilly had been so embarrassed for making it."That you are," replied Mrs. T. "But I know you learned a lesson you won't ever forget.""Of course. Herbs like their roots damp, not flooded," Jilly answered."Well that is not the lesson I was thinking of," Mrs. T. said.Jilly wondered for a minute what the lesson could be. She straightened the rows of geraniums in front of her, picking up one or two to check for aphids under the leaves. It had been a summer full of lessons, some especially hard for a girl who thought she knew a lot about plants. She breathed deeply the warm, humid air. She hated the cooped up feeling of air conditioned air, the feeling of being cut off from the sun. She knew school and the library would offer only these uncomfortable feelings and little time to spend in the sun or with plants. She had come to understand this over the summer-her need to be around growing things was huge."I'm not sure, Mrs. T." she said, "I've learned so much this summer. I couldn't possibly say what you are thinking.""You did learn many lessons, Jilly. You knew so much when you started. You've gone farther than any other assistants I've had. I will miss you.""And I will miss you," Jilly replied. "Thank you for the opportunity and the job." Jilly watched Mrs. T. put the tray of mums down on the center row of tables. Wearing her familiar brown apron, Mrs. T. looked just as she had on Jilly's first day."My pleasure, of course, dear," Mrs. T. replied. "My hope for you, as for all my assistants over the years, is that you will learn as much about yourself as you do about growing plants."Recalling her thoughts all morning, about what she enjoyed about her summer job, Jilly realized she knew much more than just how to not drown the mint.Which line from the text shows the resolution to the story? (5 points)1. The sun had been above the trees and blasting the greenhouse for a good hour now.2. Mrs. T. often claimed Jilly must be part reptile, as she was able to work longer in the greenhouse than anyone else.3.
