So the thing you wanna do is get y, and divide it by x, for example -38÷ 2=-19 , do it for each and see if -19 pops up for all of them. -19 is the answer

Answer:

y = -19x

Step-by-step explanation:

All you need to do is look at what is multiplied in the x column to get the y column.

Ex: 1 is multiplied by -19 to get -19.

2 is multiplied by -19 to get -38.

3 is multiplied by -19 to get -57.

4 is multiplied by -19 to get -76.

Work out the volume of the cone, giving your answer
Gwar [14]

Answer:

If the given lengths of 7 cm, 24 cm, and 25 cm for the sides of a triangle satisfy the equation of the Pythagorean Theorem, then, yes, the given side lengths are those of a right triangle. Let's see if they are:

The well-known equation of the famous Pythagorean Theorem is:

a² + b² = c², which says that for a right triangle, the sum of the squares of the lengths of the two shorter sides of the triangle is equal to the square of the length of the longest side called the hypotenuse, where a and b are the lengths of the two shorter sides (also called the "legs") and c is the length of the hypotenuse (the side opposite the right angle).

We're given that a = 7 cm and b = 24 cm and that c = 25 cm. Substituting these values into the equation of the Pythagorean Theorem, we get:

a² + b² = c²

(7 cm)² + (24 cm)² = (25 cm)²

(7 cm)(7 cm) + (24 cm)(24 cm) = (25 cm)(25 cm)

49 cm² + 576 cm² = 625 cm²

625 cm² = 625 cm²

As we can see, the equation of the Pythagorean Theorem is satisfied, i.e., made a true statement, by the given lengths; therefore, if these three lengths, 7 cm, 24 cm, and 25 cm, are the lengths of the sides of a triangle, then the triangle is indeed a right triangle.

On a bicycle, Esmeralda rides for 2 hours and is 12 miles from her house. After riding for 9 hours, she is 47 miles away.
In-s [12.5K]

For this case what we must do is find the speed of Esmeralda.

For this, we look for the rate of  change of the function

We have then:

AVR=\frac{y2-y1}{x2-x1}

Substituting values:

AVR=\frac{47-12}{9-2}

Rewriting:

AVR=\frac{35}{7}

AVR = 5

Answer:

Esmeralda's average rate during her trip is 5 miles per hour.

The number of new visits to a website is decreasing exponentially. It can be modeled by the function h(d)=2170(0.92)^d, where h
In-s [12.5K]

Answer:

2) -141 hits/da  

Step-by-step explanation:

Calculate the values of h(2) and h(4)

h(2) = 2170(0.92)² = 2170 × 0.8464 = 1837

h(4) = 2170(0.92)⁴ = 2170 × 0.7164 = 1555

Calculate the average rate of change

Rate of change = (y₂ - y₁)/(x₂-x₁) = (1555 -1837)/(4 - 2) = -282/2 = -141 hits/da

The average rate of change is -141 hits/da.

In the figure below, the red curve represents the function h(d), while the green dashed line represents the average rate of change over the interval 2 ≤ d ≤4.
