The answer to your question is c. y=4
3, 5, and 6 are incorrect.
In number 3, you have all the steps correct, except for the last one. Instead of adding 19 to 25, you would multiply it, because there is no addition sign in between the absolute value sign and 5^2. Thus making the answer 475.
In number 5, you first square -2. -2 * -2 ( or -2^2) = 4. Next, you square 3. 3 * 3 (3^2) is 9. Then, you subtract 9 from 4 to get -5. The absolute value of -5 is 5, making 5 the answer. Absolute value is kind of like the distance from zero, for instance -5 is 5 units away from 0 and the absolute value can never be a negative number. Thus making 5 the answer.
In number 6, you first solve the parenthesis. 2 - 3 = -1 and -1 * -1 (-1^2) is 1. Next, you square -3. -3 * -3 (-3^2) = 9. Then, you subtract 1 from 9 to get 8. The absolute value of 8, is 8. Finally, multiply -4 and 8 to get -32. Thus meaning -32 is the answer.
I hope this helps!
Its right but wrong steps 30/20 divide both by 10 is 3/2 which is 1 and 1/2
Answer:
image length is 6.89 inches
Step-by-step explanation:
Data provide:
SOD = 54 inches
OID = 8 inches
Object length = 6 inches
Now,
magnification =
also,
SID = SOD + OID
or
SID = 54 + 8 = 62 inches
Therefore,
or
Image length = - 1.148 × 6
or
Image length = - 6.89 inches
Here negative sign depicts the inverted image
Hence,
The Magnitude of the image length is 6.89 inches
