Answer:
65ft² i guess
Step-by-step explanation:
using area of rombus diagonal=½*d1*d2
Answer:
28.27cm³
Step-by-step explanation:
Area of a circle:
First, find the area of a full circle with this given radius:
Now, to find the radius of a quarter circle with the same radius, just divide by 4:
The radius of the quarter circle is about 28.27cm³
Answer:
-384
Step-by-step explanation:
geometric sequence : every new element is generated by multiplying the previous element always with the same number r.
a(n) = a(n-1) * r
a(n) = a(1) * r^(n-1)
so, a(1) = 3, r = -2
a(8) = ?
a(8) = a(1) * r^7 = 3 * (-2)^7
a negative number to an uneven power is again a negative number.
so, (-2)^7 = -128
3 * -128 = -384 = a(8)
2. Because it is being reflected across the X axis, the X coordinate would change signs, but the Y coordinate would remain the same sign.
A(-6,-4) would become A'(6,-4)
B(-3,5) would become B'(3,5)
C(1,-1) would become C'(-1,-1)
The answer would be the third choice.
3. Reflected across the Y axis, the X would stay the same sign and the Y would change signs.
P(-2,-4) would become P'(-2,4)
Q(2,-5) would become Q'(2,5)
R(-1,-8) would become R'(-1,8)
The answer would be the second choice.
