Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A block of wood has a mass of 3.5 kilogram.
- The wood has density 0.065 kg/m³.
And we need to find out the volume of the wood. Density , volume and mass are related as ,
<u>Density </u><u>:</u><u>-</u>
<u>Substitute</u><u> </u><u>the </u><u>respective</u><u> values</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Hence </u><u>the</u><u> </u><u>volume</u><u> is</u><u> </u><u>5</u><u>3</u><u>.</u><u>8</u><u>4</u><u> </u><u>m³</u><u> </u><u>.</u>
Answer:c. Y=(x-3)^2-2
Step-by-step explanation: y=(x-3)^2-2
Y=x^2-6x+7
Answer:
-3x + 5y = -24
Step-by-step explanation:
The slope = (-9-(-6) / (-7 - (-2)
= -3 / -5
= 3/5.
Using the point-slope form of a straight line:
y - y1 = m(x - x1)
y - (-9) = 3/5(x - -7)
y + 9 = 3/5(x + 7)
Multiply through by 5:
5y + 45 = 3(x + 7)
5y + 45 = 3x + 21
-3x + 5y = -24 is the required equation.
