Step-by-step explanation:

The point that partitions the segment in a ratio of 3:1 is located at :

Y = -9 + [¾ × (7-(-9)]

= -9 + (¾ × 16)

= -9 + 12

= 3

the coordinates are (2, 3)

The point that partitions the segment in a ratio of 1:3 is located at :

X = 2 + [¼×(2-2)]

= 2 + (¼×0)

= 2+0

= 2

the coordinates are (2, -5)

Jane is 5 times older than her sister. In 3 years, Jane’s sister will be 1/4 her age. Find the ages now

Korolek [52]

The present age of Jane is 45 years old and present age of her sister is 9 years old

Solution:

Let the present age of Jane be "x"

Let the present age of her sister be "y"

Jane is 5 times older than her sister

present age of Jane = 5(present age of her sister)

x = 5y ---------- eqn 1

In 3 years, Jane’s sister will be 1/4 her age

Age of sister after 3 years = 3 + y

Age of jane after 3 years = 3 + x

Age of sister after 3 years = 1/4(age of jane after 3 years)

$3 + y = \frac{1}{4}(3 + x)$

Substitute eqn 1 in above equation

$3 + y = \frac{1}{4}(3 + 5y)\\\\12 + 4y = 3 + 5y\\\\5y - 4y = 12 - 3\\\\y = 9$

Substitute y = 9 in eqn 1

x = 5(9)

x = 45

Thus present age of Jane is 45 years old and present age of her sister is 9 years old

Find all values of x in the interval [0, 2π] that satisfy the equation. (Enter your answers as a comma-separated list.) 18 + 9 c

Gekata [30.6K]

Using the identity cos(2x) = 2 cos^2x - 1
18 + 9(2 cos^2 x - 1) = 27 cos x
18cos^2 x - 27 cos x + 9 = 0
2 cos^ x - 3 cos x + 1 = 0

(2 cos x - 1 )(cos x - 1 ) = 0

cos x = 1/2 , 1

x = pi/3, 5pi/3, 0, 2pi answer

Solve the quadratic function by completing the square. What are the missing pieces in the steps? -32=2(x^2+10)

pychu [463]

-32+50 =2(x^2+10x+25)
18=2(x+5)^2
9= (x+5)^2
+- 3 = x+5
x= -2 or x= -8
