Answer:
x = 2
Step-by-step explanation:
The minimum point of the curve is (2, 0). Hence, axis of symmetry is x = 2
Answer:
Line m is not parallel to Line n.
Line m is perpendicular to Line k
Step-by-step explanation:
1. Calculate slopes of n and m. N = -2 and M = -7/4. The two slopes aren't the same thus they are not parallel
2. Slope of m = -7/4 and k = 4/7. By definition of perpendicular these two fit the description. (to be perpendicular, k = -1/m
Solution:
Given: 35.052
The standard form is: 35.052
3 is in the tens place. 3 = 3 × 1
5 is in the tens place. 5 = 5 × 1
0 is in the tenths place. 0.0 = 0 × 1/10
5 is in the tenths place. 0.05 = 5 × 1/100
2 is in the tenths place. 0.002 = 2 × 1/1000
Answer:
The astronaut must be at 1600 km from the earth to weight 64lb
Step-by-step explanation:
As the weight of an object varies inversely as the square of the distance from the center of the earth, that means that:
weight = k / distance² <em>(1)</em>
Where k is proportionality constant
Replacing:
100 lb = k/(6400km)²
100lb × 6400km² = k = 4,096x10⁹ lbkm²
Now, using (1):
64 lb = 4,096x10⁹ lbkm² / x²
x² = 4,096x10⁹ lbkm² / 64lb
x² = 6,4x10⁷ km²
x = √6,4x10⁷ km²
x = 8000 km
Distance from the center of the earth is 8000 km. Distance from the earth (At sea level):
8000km - 6400km =<em> 1600km</em>
I hope it helps!
Answer:
13
Step-by-step explanation:
because the ultimate value bars are around the -5 it’s value becomes 5
5+8= 13
