Which of the following is the equation of a line perpendicular to the line 7= –3/2 x + 4
frosja888 [35]

Answer:

Option c is correct !!

Step-by-step explanation:

[ Refer to the attachment ]

As y = mx + c is an equation to represent the straight line ; we equate the given line with this equation !!

Where m is slope of the line

and c is y intercept !!

We get , m = -3/2 and c = 4

Also, two perpendicular lines follows the equation :-

(m1)(m2) =  - 1

Where m nth is slope of nth line !!

Writing a Linear Equation Given Two Points
sveticcg [70]

Answer:

y=-3x+5

Step-by-step explanation: y=mx+b

to find slope (m) use the equation \frac{y2-y1}{x2-x1} \\

so

\frac{-10-(-1)}{5-2} = -3

to find b

use y=mx+b

-1=-3(2)+b

-1=-6+b

5=b

Hope this helps :)

1.John has a sink that is shaped like a half-sphere. The sink has a volume of 1072 in. One day, his sink
Vlad [161]

Answer:

\large\boxed{\large\boxed{85cups}}

Explanation:

<u>1. Volume of a cup</u>

The shape of the cup is a cylinder. The volume of a cylinder is:

       \text{Volume of a cylinder}=\pi \times (radius)^2\times height

The diameter fo the cup is half the diameter: 2in/2 = 1in.

Substitute radius = 1 in, and height = 4 in in the formula for the volume of a cylinder:

         \text{Volume of the cup}=\pi \times (1in)^2\times 4in\approx 12.57in^3

<u>2. Volume of the sink:</u>

The volume of the sink is 1072in³ (note the units is in³ and not in).

<u>3. Divide the volume of the sink by the volume of the cup.</u>

This gives the number of cups that contain a volume equal to the volume of the sink:

          \dfrac{1072in^3}{12.57in^3}=85.3cups\approx 85cups

Is Statistics mathematics or science? Defend your answer.
siniylev [52]

Statistics is related to maths because we study, use and even consider statistic problems with reference to mathematics.

• It is mostly used to find the census, which is maths.

• It is used to find interest rates and other banking terms using statistics, which is again related to math.

• It is also used to find the average people living in a village or panchayat, which is also math.

Therefore I strongly believe that Statistics is Maths.

Thank You!
