Answer:
D
Step-by-step explanation:
the domain of this is x>=7
the range is x<=1
so 6 is in neither
Answer:
B. 7.35 inches
Step-by-step explanation:
In the triangle:
- A=63°
- c = 7.75 inch
- B = 47°
Now we know that:
Using the Law of Sines
Answer:
1/8
Step-by-step explanation:
3/4 is the same as 6/8. 6/8 plus 1/8 is 7/8. 8/8 minus 7/8 is 1/8.
Answer:
b = -6.5
Step-by-step explanation:
92 - 16b = 12
now you want to get the number(s) and variables on different sides
92 - 16b - 92 = -16b
12 + 92 = 104
-16b = 104
now divide each side by -16
-16b / -16 = b
104 / -16 = -6.5
b = -6.5
Answer: the base is 28 inches. The altitude is 9 inches
Step-by-step explanation:
Let h represent the altitude of the sign.
Let b represent the length if the base of the sign.
The warning sign is triangular in shape.
The formula for determining the area of a triangle is expressed as
Area = 1/2bh
The base of the sign is 9 inches longer than the altitude. This means that
b = h + 9
If the area of the sign is 266 square inches, it means that
266 = 1/2 × h(h + 9)
266 × 2 = h(h + 9)
532 = h² + 9h
h² + 9h - 532 = 0
h² + 28h - 19h - 532 = 0
h(h + 28) - 19(h + 28) = 0
h(h + 28) - 19(h + 28) = 0
(h + 28)(h - 19) = 0
h = 19 or h = - 28
Since the height cannot be negative, then h = 19
b = h + 9 = 10 + 9
b = 28
