Answer:
598,500 square miles or square miles.
Step-by-step explanation:
We have been that area area of Alaska is about square miles. The area of Rhode Island is about square miles. We are asked to find the the difference between the area of Alaska and the area of Rhode Island.
To find the difference of areas we will subtract area of Rhode Island from area of Alaska as:
Now, we will convert our given area in standard form.
Therefore, the difference between the area of Alaska and the area of Rhode Island is 598,500 square miles or square miles.
Answer:
The digit in the ones spot will come out to be 4.
Step-by-step explanation:
Since the are both an even number of ten, and you're subtracting 6, their both gonna come out to have a 4 in the ones spot in the number answer.
Answer:
B = 48.7°
C = 61.3°
b = 12
Step-by-step explanation:
Given:
A = 70°
a = 15
c = 14
Required:
B, C, and b
Solution:
✔️Using the law of sines, let's find C:
Sin C/c = Sin A/a
Plug in the values
Sin C/14 = Sin 70/15
Cross multiply
Sin C × 15 = Sin 70 × 14
Divide both sides by 15
Sin C = (Sin 70 × 14)/15
Sin C = 0.8770
C = Sin^{-1}(0.8770)
C = 61.282566° = 61.3° (nearest tenth)
✔️Find B:
B = 180 - (70 + 61.3) (sum of triangle)
B = 48.7°
✔️Find b using the law of sines:
b/sinB = a/sinA
Plug in the values
b/sin 48.7 = 15/sin 70
Cross multiply
b*sin 70 = 15*sin 48.7
Divide both sides by sin 48.7
b = (15*sin 48.7)/sin 70
b = 11.9921789
b = 12.0 (nearest tenth)
F(x)>0 or y>0
interval notation: (0,∞)
Answer:
The equation can't have one imaginary solution.
