Because you have to line the decimals up to make sure you have the correct answer
Answer:
8.14 feet
Step-by-step explanation:
8.14 feet will be more precise because it measures to the hundredths place, while 13.2 feet only measures to the tenths place.
Measuring to smaller place values increases precision and accuracy because the measurements are more likely to be more exact and correct.
So, 8.14 feet is more precise
Answer:
-2 is a zero of the polynomial. 2 is not a zero of the polynomial.
Step-by-step explanation:
A value of x is a zero of a polynomial if when it is substituted for x in the polynomial, it makes the polynomial evaluate to zero.
The polynomial is x + 2
Let x = -2:
x + 2 = -2 + 2 = 0
-2 is a zero of the polynomial.
Let x = 2:
x + 2 = 2 + 2 = 4
2 is not a zero of the polynomial.
Answer:
x=-3
Step-by-step explanation:
x-2+3=-2
Add 2 to both sides:
x+3=0
Subtract 3 from both sides:
x=-3

Answer:
21
Step-by-step explanation:
When secants meet, the product of the length of the pieces from the meeting point to the two circle intersection points is the same for all.
KL·KM = KJ·KC
Assuming the marks inside the circle apply only to the lengths inside the circle:
8(8+x+5) = 7(7+2x+1)
104 +8x = 56 +14x
48 = 6x
8 = x
Then the measure of MK is ...
MK = x+13 = 8+13
MK = 21
