Answer:
530.66 cm^2
Explanation:
Equation: 3.14•13^2
13^2= 169
3.14•169= 530.66
Answer:
y=x+1
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(0-(-6))/(-1-(-7))
m=(0+6)/(-1+7)=6/6=1
y-y1=m(x-x1)
y-(-6)=1(x-(-7))
y+6=x+7
y=x+7-6
y=x+1
Answer:
C
Step-by-step explanation:
First, to make things simpler, let's create a common denominator for every term. We can do this by multiplying (x+4) and (x+3) when the denominator has a (x+3) or (x+4), respectively. In other words:
Now that they all have a common denominator, we can combine them:
Now, divide them. Recall how to divide fractions. You "flip" the second term and change the division sign into a multiplication sign.
Notice the denominator of the first term and the numerator of the second; we can cancel them out.
Now, we just need to simplify.
Answer:
+49 feet
Step-by-step explanation:
The inicial position that Suzie started her hike was 220 feet below sea level, so as this inicial position was negative, let's use the negative sign for it:
Inicial position = -220 feet
The final position of the hike was 171 feet below sea level, so:
Final position = -171 feet
So we calculate the change in elevation from the beginning to the end of the hike by making the difference between the final position and the inicial position:
Change in elevation = Final position - Inicial position = -171 - (-220) = -171 + 220 = +49 feet
The change in elevation was +49 feet (the positive sign indicates that the movement was upwards, in direction to "above sea level")
