How do you find the coordinates of two points given an equation?

Answer:

  30%

Step-by-step explanation:

You want the percentage reduction each year that will result in a reduction of 51% over two years.

The growth factor is 1 added to the growth rate. If the desired growth rate over 2 years is -51%, then the growth factor for that period is ...

  1 -51% = 0.49

If the growth factor is the same for each of two years will be ...

  (1 +r)² = 0.49 . . . . . . . where r is the growth rate each year

Solving for r gives ...

  1 +r = √(0.49) = 0.7

  r = 0.7 -1 = -0.3 = -30%

The required growth rate each year is -30%.

The pollution must be reduced by 30% each year for 2 years.

The missing numbers are 14 and 17. there are 50 steps taken to reach the last pebble on this part of the path.

What is the missing number?

Missing numbers are the numbers that have been missed in the given series of a number with similar differences among them.

let's take a look at pebbles along each part of the path, there is 1 number of addition to each pebble number to go on next pebble.

i.e. 12, 13, 14, 15, 16, 17

so, the missing numbers are 14 and 17.

now, as given Hansel and Gretel used a pebble to mark every 10 steps as they walked along the path. How many steps have they taken when they get to the last pebble on this part of the path?

so, to go on next pebble there are 10 steps to walk.

therefore, from starting pebble  number 12 to last pebble number 17, there are 50 steps ( difference between two pebbles is 10 steps).

hence, the missing numbers are 14 and 17. there are 50 steps taken to reach the last pebble on this part of the path.

The three steps of factoring include taking the common component out of the polynomial then simplifying the polynomial such that the most simple values are left and finally rearrangement.

If we are provided with the polynomial that is very complex in nature then first thing we have to do in order to solve the problem related to that polynomial is to factorise the polynomial.

The factory of that particular polynomial can be done by taking out the most common component out of the polynomial in a multiplication.

After this we have to simplify the polynomial such that only the simplest values are left in the polynomial and finally we have to rearrange the polynomial because after such operations on that polynomial the polynomial will not be easy to understand in the first look of it.

The final solution of the given integral ∫ ([tex]x^3[/tex] - 2) dx is ([tex]x^4[/tex])/4 - 2x + C.

To integrate ∫ (x^3 - 2) dx, we use the power rule of integration, which states that ∫[tex]x^n[/tex] dx = ([tex]x^{(n+1)}[/tex])/(n+1) + C, where C is the constant of integration.

In this case, we have [tex]x^3[/tex] as the inside function, so we apply the power rule by raising the exponent by 1 and dividing by the new exponent. This gives us ([tex]x^4[/tex])/4 + C as the antiderivative.

However, we also have the constant term -2. To integrate a constant term, we add it as a separate term to the antiderivative. So the final solution is ([tex]x^4[/tex])/4 - 2x + C.

There are 80 dogs and 20 cats in the animal shelter.

The ratio of dogs to cats is 4:3. This means for every 4 dogs, there are 3 cats. We know that there are 40 more dogs than cats.

To calculate the number of each animal, we can set up the equation 40 = 4x - 3x, where x represents the number of cats.

After solving the equation, we get x = 20. This means that there are 20 cats in the animal shelter. To find the number of dogs, we can use the ratio. We know that for every 4 dogs, there are 3 cats. So, for 20 cats, there must be 4 × 20 = 80 dogs.

Therefore, there are 80 dogs and 20 cats in the animal shelter.

By 30 multiply both sides.

1 foot Equals 2/30 inches.

Now,

1 foot Equals 2/30 inches.

180 times on both sides.

180 feet = 180 x 2/30 inch

180 feet equals 6 by 2 inches.

120 feet equals 12 inches.

Thus,

Considering that a foot equals two inches, a sports arena's height would be 180 feet.

The scale model of both the sports stadium has a 12 inch height.1 foot Equals 2/30 inches.

Now,

1 foot Equals 2/30 inches.

180 times on both sides.

180 feet = 180 x 2/30 inch

180 feet equals 6 by 2 inches.

120 feet equals 12 inches.

Answer:The slope of the given line is -4

Step-by-step explanation:

when x is 0.5 then y value is 3, x is 1.5 then y is 9 and x is 4.5 then y is 27.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

A proportion is an equation in which two ratios are set equal to each other

In the given table the value of x is 0.5 and value of y is 3

y/x=3/0.5=6

In the second row the value of x is 1.5 we need to find value of y.

3/0.5=y/1.5

4.5=0.5y

Divide both sides by 0.5

y=9

In third row the value of x is 4.5 and y is 27

Hence, when x is 0.5 then y is 3, x is 1.5 then y value is 9 and x is 4.5 then y is 27.

Answer:

y = 1425 * (1 + 0.05)^x

Step-by-step explanation:

An exponential function of the form y = a * b^x can be used to model exponential growth or decay, where a is the initial value, b is the base (growth or decay factor), and x is the time period. In this case, the initial value is 1,425 and the rate of increase is 5%. We can write this as an exponential function as follows:

y = 1425 * (1 + 0.05)^x

where y is the final value after x time periods, and x is the number of time periods (in years, for example). To find the value of the function after x time periods, you can substitute the value of x into the equation.

Trucks will be able to pass through tunnel B while tunnel A is destroyed.In light of this, the equations for tunnels A and B are x2 + y2 + 30x + 56 = 0 and x2 - 30x + 16y - 95 = 0, respectively.

A parabola's general equation is either y = a(x-h)2 + k or x = a(y-k)2 + h, where (h, k) stands for the vertex.

y2==4ax is the typical equation for a normal parabola.

Section A: x2+y2+30x+56=0

On both sides of an equation, add 152.

This is,

x²+30x+15²+y²=-56+15²

⇒ (x+15)²+y²=169⇒ (x+15)²+y²=13²

On both sides of the equation, divide 132.

⇒ (x+15)²/13² + y²/13² =1

Part B:x²-30x+16y-95=0

x2-30x+16y=95 now,

On both sides of an equation, add 152.

In other words, x2-30x+152+16y=95+152

⇒ (x-15)²=320-16y

⇒ (x-15)²=16(20-y) (20-y)

Part C:greatest height:A: 13 feet

B: 20 feet ,8 feet wide

A: x+15=8/2=4 y=12.37<13.5

A right triangle is any triangle that has a 90-degree angle.

A 30-60-90 triangle is a special type of right triangle that has a 30-degree angle and a 60-degree angle in addition to the right angle.

The side opposite the 30-degree angle is called the shorter leg.

The side opposite the 60-degree angle is called the longer leg.

The side opposite the right angle of 90 degrees is called the hypotenuse.

The hypotenuse is twice the shorter leg.

The longer leg is √3 times the shorter side.

if the length of the shorter leg is given, then these properties are used to find the longer side and the hypotenuse.

However, the 30-60-90 properties hold no matter which side is provided.

If the length of the hypotenuse is given, divide it by 2 for the shorter leg. Then multiply that result by √3 to get the length of the longer leg.

If the length of the longer leg is given, divide it by √3 to get the shorter leg. Then, multiply that result by two to get the length of the hypotenuse.
