PLEASE Find the equation of the line............................perpendicular to the line y= 5x -1 and passes through the points

Since it's perpendicular to the line with the slope 5, you take the reciprocal of 5 which is 1/5 and change the sign: -1/5. So you have the equation: y=-(1/5)+b. To find b you substitute x and y for the coordinate (10,8). 
y=(-1/5)x+b
8=(-1/5)10+b
8=(-10/5)+b
8=-2+b
<u>+2 +2</u>
10=b

So your new equation is: y=<u>1x</u>+10

Well we know that...a^{-1}=\frac{1}{a^{1} }\\.

So...(\frac{1}{5})^{-1}=\frac{1}{\frac{1}{5}^{1}}=5\\\\.

Because 5^{3}=125,

\frac{1}{5}^{-1*3}=125\\  x=-1*3=-3

answer: -3

On a linear X temperature scale, water freezes at −115.0°X and boils at 325.0°X. On a linear Y temperature scale, water freezes
belka [17]

Answer:

The current temperature on the X scale is 1150 °X.

Step-by-step explanation:

Let is determine first the ratio of change in X linear temperature scale to change in Y linear temperature scale:

r = \frac{\Delta T_{X}}{\Delta T_{Y}}

r = \frac{325\,^{\circ}X-(-115\,^{\circ}X)}{-25\,^{\circ}Y - (-65.00\,^{\circ}Y)}

r = 11\,\frac{^{\circ}X}{^{\circ}Y}

The difference between current temperature in Y linear scale with respect to freezing point is:

\Delta T_{Y} = 50\,^{\circ}Y - (-65\,^{\circ}Y)

\Delta T_{Y} = 115\,^{\circ}Y

The change in X linear scale is:

\Delta T_{X} = r\cdot \Delta T_{Y}

\Delta T_{X} = \left(11\,\frac{^{\circ}X}{^{\circ}Y} \right)\cdot (115\,^{\circ}Y)

\Delta T_{X} = 1265\,^{\circ}X

Lastly, the current temperature on the X scale is:

T_{X} = -115\,^{\circ}X + 1265\,^{\circ}X

T_{X} = 1150\,^{\circ}X

The current temperature on the X scale is 1150 °X.

Use a reference angle to write sec255∘ in terms of the secant of a positive acute angle. Do not include the degree symbol in you
jarptica [38.1K]

Answer: sec (75) or csc (15)

Step-by-step explanation:

255 is in the 3rd quadrant where the secant is. Here, the tangent and cotangent is positive.

Reference angle for 255 is,

255 - 180 = 75 degrees.

Therefore, sec (255) = sec (75)

= csc (90 - 75) = csc (15)
