What is the equation of a line that is perpendicular to y=0.25x-7 and passes through the point -6,8

Mathematics

Olenka [21]3 years ago
7 0

Answer:

The equation ls: y = -4x - 16

Step-by-step explanation:

Given the point (-6, 8)

Given the line y = .25x - 7

Use a fraction:

y = 1/4x - 7

The slope is 1/4 (or .25)

The slope of a perpendicular line is the negative inverse or -4.

Use the point slope form and substitute:

y - y1 = m(x - x1)

y - 8 = -4(x - (-6))

y - 8 = -4x - 24

y = -4x - 16

Proof:

f(-6) = -4(-6) - 16

= 24 - 16

= 8, giving (-6, 8)

<h3><u>Answer</u> :</h3>

\bigstar\:\boxed{\bf{\purple{x^{\frac{m}{n}}}=\orange{(\sqrt[n]{x})^m}}}

Let's solve !

:\implies\sf\:25^{\frac{3}{2}}

:\implies\sf\:(\sqrt[2]{25})^3

:\implies\sf\:5^3

:\implies\boxed{\bf{\red{125}}}

What time between 6pm and 6:30 pm the hour and minutes hands be exactly 125* degree apart
vladimir2022 [97]

Answer:

6:10pm

Step-by-step explanation:

At 6:00 the hands are 180° apart.

The hour hand moves 1/12 of circle per hour = 30° per hour = 0.5° per minute.

The minute hand moves 1/60 of the circle per minute = 6° per minute

Angle between the hands decreases by 6-0.5 = 5.5° per minute.

180 - 5.5t = 125

t = 125/5.5 = 10 minutes

The hands are 125° apart at t minutes after 6:00, or 6:10.

Present and contrast at leat 2 different methods of finding the volume of a cylinder with height h and radius r.
Vilka [71]

Answer:

Volume V= πr²h

Volume V= base * height

Step-by-step explanation:

Volume is the capacity of an object which is obtained by multiplying area with height. Volume of a cylinder is generally calculated by two formulas.

Volume of  a cylinder V= πr²h Where r is the radius and h is the height

Volume of a cylinder V= base * height

If we analyse the two formula keeping in mind that  the base of the cylinder is circular . The area of a circle is given by πr². In this first formula we can find the area of the base by applying the formula of the circular region. Volume is measured by multiplying length , breadth and height, or area with height. In both the formulas given above we find the area and then multiply with the height.
