Eric wants to get an output of 0. Can he do this with each machine? If so, how? If not, why not?
natita [175]

Answer:

  • <u>No, he can get an output of 0 with the second machine (function B) but he cannot get an output of 0 with the first machine (function A).</u>

Explanation

The way each machine works is given by the expression (function) inside it.

<u>1)  </u><em><u>Function A</u></em>

To get an output of 0 with the function y = x² + 3, you must solve the equation x² + 3 = 0.

Since x² is zero or positive for any real number, x² + 3 will never be less than 3 (the minimum value of x² + 3 is 3). So, it is not possible to get an output of 0 with the first machine.

<u>2) </u><em><u>Function B</u></em>

Solve y=\sqrt{x}-2=0

  • \sqrt{x}-2=0

  • \sqrt{x} =2

  • x=2^{2}

  • x=4

So, he can get an output of 0 by using x = 4.

May I please receive help?
Leya [2.2K]

Answer:

Step-by-step explanation:

G is the centeroid of the triangle. G splits AE in the ratio 2 : 1

AG : GE = 2 : 1

AG = 2x  and GE = x

2x = 20

x = 20/2

x = 10

GE = 10 ; AG = 20

AE = 20+10 = 30

CG : GD = 2:1

CG = 2x  and GD = x

2x = 10

x = 10/2

x = 5

GD = 5

BF = 30

BG : GF = 2 : 1

BG = 2x  ; GF = x

BF = 30

BG + GF = 30

2x + x = 30

3x = 30

x = 30/3

x = 10

GF = 10

Tom has a large photo he wants to shrink to wallet sized it's with is 20 cm and its length is 30 cm. If he wants the width to be
Anni [7]
The width was 20 cm and was brought down to 5 cm, you can see that the pictures width was shrunk down 4 times because 20 divide by 4 is 5 so to find the length you would divide 30 by 4 and get 7.5 cm as your answer.
