Answer:
d = -3
Step-by-step explanation:
Given the equation:
Solve for d:
Take both sides cube root we have;
![d =\sqrt[3]{-27}](https://tex.z-dn.net/?f=d%20%3D%5Csqrt%5B3%5D%7B-27%7D)
We can write 27 as:
then;
![d = \sqrt[3]{-3^3}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%5B3%5D%7B-3%5E3%7D)
Using the rules:
![\sqrt[n]{a^n} = a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%20%3D%20a)
![\sqrt[3]{-1} = -1](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-1%7D%20%3D%20-1)
then;
![d = -\sqrt[3]{3^3} = -3](https://tex.z-dn.net/?f=d%20%3D%20-%5Csqrt%5B3%5D%7B3%5E3%7D%20%3D%20-3)
therefore, the unknown variable d is, -3
Answer:
119.4cm^2
Step-by-step explanation:
Area of rectangle = 132cm^2
Area of circle = 12.6cm^2
Shaded region = 132cm^2 - 12.6cm^2 = 119.4cm^2
Answer:
B. y=1/2x-5
Step-by-step explanation:
From the graph, we read the slope of line JK.
slope = rise/run = -3/-6 = 1/2
The equation we need has the same slope.
y = mx + b
y = (1/2)x + b
It passes through point P(6, -2). Now we find b.
-2 = (1/2)(6) + b
-2 = 3 + b
b = -5
The equation is
y = (1/2)x - 5
