Answer:
-4
Step-by-step explanation:
plug in -2
-(-2)^2 = -4
Answer:
5sqrt3
Step-by-step explanation:
Using the pythagorean theorem, we have a^2+4^2=9^2
a^2 + 16 = 81
a^2 = 75.
a = sqrt75.
75 = 25*3. 25 is a perfect square, so sqrt75 = 5sqrt3
Answer:
133.78684807256
Step-by-step explanation:
step 1: We need the assumption that 44.1 is 100% since it is our output value
step 2: We need to represent the value we seek in x
step 3: From step 1, it follows that 100% = 44.1
step 4: In the same vein x% = 59
step 5: This give us a pair of simple equations:
100% = 44.1 (1)
x% = 59 (2)
step 6: by simplify dividing equation 1 by equation 2 and taking note of the fact that both the LHS (left hand side) of both equations have the same unit (%); we have

step 7: Taking the inverse (or reciprocal) of both sides yields

= x = 133.78684807256
Therefore, 59 is 133.78684807256% of 44.1
Answer:
umm decrease
Step-by-step explanation:
Answer:
1 : 18
Step-by-step explanation:
When finding scale factor, both measurements should in same unit
Circumference of the model bell = 8 inches
1 feet = 12 inches
12 feet = 12 * 12 = 144 inches
Circumference of the actual bell = 12feet = 144 inches
Model : Actual = 8 : 144
= 8÷8 : 144÷8
= 1 : 18
