The population of a local species of dragonfly can be found using an infinite geometric series where a1 = 42 and the common rati

Mashutka [201]

we are given

first term is

$a_1=42$

common ratio is

$r=\frac{3}{4}$

now, we can find nth term

$a_i=a_1(r)^{i-1}$

now, we can plug values

$a_i=42(\frac{3}{4})^{i-1}$

now, we can write in sigma form

$sum=\sum _{i=1}^{\infty }\:42(\frac{3}{4})^{i-1}$

now, we can find sum

we can use formula

$sum=\frac{a}{1-r}$

now, we can plug values

we get

$sum=\frac{42}{1-\frac{3}{4}}$

$sum=168$

so, option-D.................Answer

7.find the equation of a circle with one of the diameters x+2y+8=0and passing through the intersection of a circle x²+y²+2=0 and

ozzi

Answer:

See below

Step-by-step explanation:

Find the intersection of circles

x² + y² + 2x = 0 and
x² + y² - 3y = 0

Subtract the equations to find:

2x = -3y ⇒ y = -2/3x

By substitution find the points:

(0, 0) and (-1.385, 0.923)

Find midpoint between these two points:

x = (0- 1.385)/2 = -0.6925 , y = (0 + 0.923)/2 = 0.4615

Find perpendicular bisector passing through this point:

y - 0.4615 = 3/2(x + 0.6925)
y = 1.5x + 0.4615 + 1.5(0.6925)
y = 1.5x + 1.50025

Find intersection of the lines, it is the center:

y = 1.5x + 1.50025
x + 2y + 8 = 0

Solving we get:

x = -2,75, y = -2.625

Find radius, the distance from center to point (0, 0) and get equation of circle:

(x + 2.75)² + (y + 2.625)² = (0 + 2.75)² + (0 + 2.625)²
x² + 5.5x + y² + 5.25y = 0
4x² + 22x + y² + 21y = 0
4x² + 4y² + 22x + 21y = 0

Simplify the exponential expression 48 ^1/2

Ostrovityanka [42]

Step-by-step explanation:

Hi There! Let me help you :)

To answer this question, we have to know about the way to simplify it. First, you find the factor of 48.

$= {48}^{ \frac{1}{2} }$

$= {(16 \times 3)}^{ \frac{1}{2} }$

$= {16}^{ \frac{1}{2} } \times {3}^{ \frac{1}{2} }$

$\:$

—Use the general formula of the exponential, where a^m/n = ^n√a^m.

$\:$

$= {16}^{ \frac{1}{2} } \times {3}^{ \frac{1}{2} }$

$= \sqrt[2]{16} \times {3}^{ \frac{1}{2} }$

$= 4 \times {3}^{ \frac{1}{2} }$

The answer is C.
