Answer:

Rate

Step-by-step explanation:

The rate of one quantity with another quantity (usually of different units) is the ratio that compares those two quantities. In other words, a rate is a comparison of two quantities of different units in ratio form. For example;

We know that velocity is the rate at which distance changes with time. This means that velocity is a rate comparing two different quantities which are distance and time which both have different units. Distance has an S.I unit of meters(m) while time has an S.I unit of seconds(s). This can be written as follows;

Velocity = distance : time or $\frac{distance}{time}$

Answer:

Rate

Step-by-step explanation:

Rate is basically also a ratio. but it is the comparing of two different quantities with different units.

As ratio is comparing of same or identical quantities thus it has no units. But on the other hand as rate is the comparison of different quantities, thus it has units.

for example:

When i compare two quantities, 1st is a distance quantity and 2nd is a time quantity i.e.

20 meters : 15 seconds

thus the lowest form of this relationship will be:

4 meters : 3 seconds

when i write it in Decimal form it becomes :

Ans : 1.33 meters/second (Distance per unit time)

As this ratio have remaining units thus it is referred to as "RATE".

Step-by-step explanation:

Remark

The measurement of the arc is 3Pi

that represents 108 / 360 of the circle.

Equation

108/350 2 * pi * R = 3* pi

Solution

Pi is on both sides of the equation. They both cancel.

108/360 = 0.3

0.3 * 2 * R = 3

0.6 * R = 3

R = 3/0.6

R = 5

given y>0 and dy/dx=(3x^2+4x)/yif the point (1,√10) is on the graph relating x and y, then what is y when x=0

jonny [76]

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{3x^2+4x}y\iff y\,\mathrm dy=(3x^2+4x)\,\mathrm dx$
$\implies\displaystyle\int y\,\mathrm dy=\int(3x^2+4x)\,\mathrm dx$
$\implies \dfrac12y^2=x^3+2x^2+C$

When $x=1$ you have $y=\sqrt{10}$ , so

$\dfrac12(\sqrt{10})^2=1^3+2(1)^2+C\implies 5=1+2+C\implies C=2$

and so the particular solution to the ODE is

$\dfrac12y^2=x^3+2x^2+2$

Then when $x=0$ , you get

$\dfrac12y^2=0^3+2(0)^2+2=2$
$\implies y^2=4$
$\implies y=2$

where we omitted the negative root because it's given that $y>0$ .

What must be true regarding the distribution of the population? A. The population must be normally distributed and the sample s

Karolina [17]

Answer:

C. The population must be normally distributed.

Step-by-step explanation:

Population distribution have to do with the classification of people living in a particular geographical area into different segment such as Age, Occupation, Sex, Geographical location.

For instance

If Age distribution is use, the total number of people living in say New york will classified into 0-10 11-19years 20-29years and so on

Sex distribution involves distribution into the male and Female Category

Occupation distribution of Population involves classification of occupant of an area according to their Job.. I.e.Drives-15 people, Lawyer =2 people and so on.

Geographical location distribution of population involves the classification of people living in a particular country according to their geographical names. I.e. Abuja=3.5million people etc.

Lelu [443]

Answer:

Jaden has to plant the geranium in the circumcentre of the triangular yard in order such that it is equidistant from all its vertices.

Step-by-step explanation:

In Jaden’s yard, there is a triangular garden patch. He wants to plant a geranium in the patch at a point equidistant from all its vertices.

" The CIRCUMCENTER (C) of a triangle is the point in the plane equidistant from the three vertices of the triangle "

Hence Jaden has to plant the geranium in the circumcentre of the triangular yard in order such that it is equidistant from all its vertices.

the 30°-60°-right triangle theorem states that the
In a right triangle, the hypotenuse is twice as long as a leg if and only if the measure of the
angle opposite that leg is 30°
so the option C is correct from above all
see the figure
