The number of red beads are increasing by 2 for each new pattern
The next number of reds will be 12. ( in patern 5)

number of blue beads in pattern 5 will be 15 ( increasing by 3 )

nth term for red = 4 + 2 (n-1) ( its an arithmetic sequence)

nth term for blue = 3 + 3(n - 1) - as above ,arithmetic.

Total beads in pattern 45 is

No. red beads in pattern 26 = 4 + 2(26-1) = 4 + 50 = 54
No blue beads in pattern 60 = 3 + 3(59) = 180

Total number of beads in pattern 45 is:-

4 + 2(44) + 3 + 3(44) = 227

Saira is using the formula for the area of a circle to determine the value of .

klio [65]

For this problem, we just have to use the values we're given to calculate the approximate value of pi.

The formula presented is

$\pi=Ar^{-2}$

When you have a negative exponent, we can use the following property

$a^{-b}=\frac{1}{a^b}$

Using this property, our problem turns out to be

$\pi=\frac{A}{r^2}$

Now, we just need to plug the given values on this equation

$\pi=\frac{50.265}{4^2}=3.1415625\approx3.142$

The approximated value for pi is 3.142.

A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. When he started his diet, he weighed

zavuch27 [327]

Answer:

(Choice A) A graph of an increasing linear function in quadrant 1 with a positive y-intercept.

Step-by-step explanation:

The weight of the sumo wrestler starts at a positive value of 79.5 kilograms, and we are given that the sumo wrestler gains a linear amount of weight per month at 5.5 kilograms per month.

If we were to graph this relationship, the sumo wrestler's weight would be represented on the y-axis, and the amount of time on the x-axis.

So the initial weight would occur at (0, 79.5) which is the positive y-intercept.

And since his weight is increasing at 5.5 kilograms per month, the slope of the linear function is positive.

Hence, the graph of the linear increasing function in quadrant 1 with a positive y-intercept.

Cheers.

L1 : y = 2x , (2) find the equation of the line L2 perpendicular to L1 passing through the point P = (1, 2).

just olya [345]

Answer:

Step-by-step explanation:

Given the line L1 as y = 2x perpendicular to an unknown line L2 passing through the point P = (1, 2), we are to find the equation of line L2. to find the equation of the line L2, we will use the point-slope equation of a line expressed as y-y₀ = m(x-x₀)

m is the slope of the unknown line

(x₀, y₀) is the given point.

First is to get the slope of the known line:

comparing the line L1: y = 2x with the standard equation of the line y = mx+c, it can be seen that m = 2

Then we will calculate the slope of the required line.

Since L1 is perpendicular to L2, the product of their slope will be -1 i.e

mm₁ = -1 where m₁ is the slope of the required line L2.

Given m =2

m₁ = -1/m

m₁ = -1/2

Finally we will calculate the equation of line L2 by substituting the slope of line L2 and the point in the point slope equation above;

y-y₀ = m(x-x₀)

Given (x₀, y₀) = (1,2) and m₁ = -1/2

y-2 = -1/2(x-1)

open the parenthesis

y-2 = -x/2+1/2

multiply through by 2:

2y-4 = -x+1

2y+x = 1+4

2y+x = 5

<em>Hence the equation of the line L2 is 2y+x = 5</em>
