What is the equation of a line, in general form, with a point (-3, 0) and an undefined slope?
irina1246 [14]
Undefined slope...with a point (-3,0)

ok u need to learn this...
VUX -- vertical line, undefined slope, represented by x = the x in (x,y)
HOY -- horizontal line, 0 slope, represented by y = the y in (x,y)

so ur line would be : x = -3...but in general form, it is Ax + By + C = 0....so this equation would be x + 0y + 3 = 0...I think

What is the area of the cross section if the length is 12 cm and the width is 10 cm?
VARVARA [1.3K]

Answer:

120 cm²

Step-by-step explanation:

From the question;

  • Length is 12 cm
  • Width is 10 cm

We are required  to determine the area of the cross section;

  • Note that the cross section is the plane of a solid that remains constant through the solid.
  • In this case, the cross section is a rectangle whose dimensions are 12 cm by 10 cm.

But Area of a rectangle = Length × Width

Therefore;

Area of cross section = 12 cm × 10 cm

                                   = 120 cm²

Thus, area of the cross section is 120 cm²

During the worst periods of hyperinflation in a certain country, the price of food increased at a rate of 30% per month. State w
Serhud [2]

Answer:

It was an exponential increase

In 3 months, the bill will be $285.61

Step-by-step explanation:

First, this scenario is exponential, because the price of food is increasing with a percentage, based on the price that it was the previous amount.

Next, to find what the bill will be in 3 months, an equation needs to be made representing the situation.

Use the standard exponential equation: y = ab^x, where a is the initial amount, b is the growth rate, and x is the amount of time.

Plug in the values we know:

y = 130(1.3)^3

Solve for y

y = 285.61

So, 3 months later, the bill will be $285.61
