A is inversely proportional to b. If a=7.2 when b=-4, what will a equal when b=6?
Tpy6a [65]

Answer:

<h2>a = - 4.8</h2>

Step-by-step explanation:

To find the value of a when b=6 we must first find the relationship between them.

The statement

a is inversely proportional to b is written as

a \:  \:  \alpha  \:  \:  \frac{k}{b}

where k is the constant of proportionality

When a = 7.2 , b = -4

So we have

7.2=  \frac{k}{ - 4}

k = 7.2 × - 4

k = - 28.8

So the formula for the variation is

a =  -  \frac{28.8}{b}

When

b = 6

That's

a =  -  \frac{28.8}{6}

We have the final answer as

<h3>a = - 4.8</h3>

Hope this helps you

Which rule represent the reduction of a figure?
vazorg [7]

Answer:

Correct option: second one

Step-by-step explanation:

Let's check each option to find the correct one.

First option: x and y increase by 2.3 times, so the figure expands. So this is not the correct option.

Second option: x and y decrease 0.52 times, so the figure is reduced. So this is the correct option.

Third option: x and y are translated by 1/3 of their position, so the figure is not reduced.

Fourth option: x and y increase by 7/2 times, so the figure expands. So this is not the correct option.

Correct option: second one

If n lines are drawn in a plane, how many regions do they separate the plane into? induction
grandymaker [24]
Hello,

Let's assume i the number of lines,
 u(i) the number of regions:

u_0=1\\\\&#10;u_1=2=1+1=1+u_0\\\\&#10;u_2=4=2+u_1\\\\&#10;u_3=7=3+u_2\\\\&#10;u_4=11=4+u_3\\\\&#10;u_5=16=5+u_4\\\\&#10;...\\\\&#10;\boxed{u_{n+1}=(n+1)+u_{n}}\\\\&#10;&#10;u_{n+1}=(n+1)+n+(n-1)+...+1+u_0\\\\&#10;&#10;\boxed{u_{n+1}= \dfrac{(n+1)*(n+2)}{2}+1 }

What is the length of segment AC?
Brut [27]

Making a triangle with line segment AC as the hypotenuse, we see the two legs are 6 and 8 units. Using the Pythagorean theorem, 6^2=36 and 8^2=64. 36+64=100. The square root of 100 is 10, so the length of AC is 10 units. Please give me brainiest. Have a great day.
