<span>I think the answer would be:
B) y= 4 cos 2 theta</span>
Answer:
y = x + 2
Slope = rise / run
= 2 / 2 (or 1 bc 2 divided by 2 is 1)
The plotted point on the x axis is on 2
y = x + 2
120/21= 5.71
Students wouldn't be splitting a Skittle, so everyone would get 5.
Answer:
Gold
Step-by-step explanation:
<em>Casandra finds a treasure chest packed with metallic coins. The chest has a volume of 0.25 cubic meters. The coins have a combined mass of 4825 kg. Hoping to find gold, she calculates the density to determine the metal of the coins.</em>
<em>What kind of metal are the coins made of?</em>
<em>Bronze (8700 kg per cubic meter)</em>
<em>Silver (10500 kg per cubic meter)</em>
<em>Lead (11300 kg per cubic meter)</em>
<em>Gold (19300 kg per cubic meter)</em>
<em />
Density is mass per volume:
D = M / V
D = (4825 kg) / (0.25 m³)
D = 19,300 kg/m³
The coins must be made of gold.
Answer:
The equation would be x + 2y = -8
Step-by-step explanation:
To find the standard form of this line, start by using point-slope form with the given information. Then solve for the constant.
y - y1 = m(x - x1)
y + 3 = -1/2(x + 2)
y + 3 = -1/2x - 1
1/2x + y + 3 = -1
1/2x + y = -4
x + 2y = -8
