A = 9 (Sorry I can't do the other ones, I haven't learned those ones yet) Hope this helps!! :P
Answer:
C. 0≤x≤7
Step-by-step explanation:
It is not choice D. because it has y instead of x. It is supposed to be x because it is asking for domain.
Hope this helps!
Answer:A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Write and solve an equation to find the length of each side of the triangle.
The sides can be found by taking the square root of the area. , where = side. . So the length of a side is 6.3 cm.
Step-by-step explanation:
Answer:
10 ft²
Step-by-step explanation:
Recall that the volume of a uniform cylinder may be defined by the formula:
Volume = Base Area x Height
In our case we are given
Volume = 15 ft³ and Base Area = 1.5 ft
Substituting these known values into the formula gives:
Volume = Base Area x Height
15 = Base Area x 1.5
Base Area = 15 / 1.5
Base Area = 10 ft²
Since b = c, the angles B and C are congruent.
180 - 45 = 135
135/2 = =67.5
A = 45
B = 67.5
C = 67.5
a = ?
b = 4
c = 4
Since we know two sides and all three angles, we can use the law of sines to find a.
b/sin B = a/sin A
4/(sin 67.5) = a/(sin 45)
a = 4(sin 45)/(sin 67.5)
a^2 = (4(sin 45)/(sin 67.5))^2
a^2 = 9.37
