Find the other endpoint of the line segment with the given endpoint and midpoint. Endpoint: (-2, -6) Midpoint: (-5, 1)
FromTheMoon [43]

Answer:

(-8,8)

Step-by-step explanation:

The midpoint M(x_M,y_M) of the segment AB with endpoints A(x_A,y_A) and B(x_B,y_B) has coordinates

x_M=\dfrac{x_A+x_B}{2}\\ \\y_M=\dfrac{y_A+y_B}{2}

In your case, A(-2,-6), \ M(-5,1), then

-5=\dfrac{-2+x_B}{2}\Rightarrow -2+x_B=-10,\ x_B=-10+2=-8\\ \\1=\dfrac{-6+y_B}{2}\Rightarrow -6+y_B=2,\ y_B=2+6=8

Jethro is planting flowers in his garden. He wants the ratio of tulips to roses to be 2 to 1. Jethro wants to plant a total of 1
attashe74 [19]

Given:

Ratio of tulips to roses = 2:1

Total number of flowers = 18

To find:

The number of tulips.

Solution:

Let the number of tulips and roses are 2x and x respectively.

According to the question,

2x+x=18

3x=18

Divide both sides by 3.

x=\dfrac{18}{3}

x=6

Now,

Number of tulips =2(6)

                           =12

Therefore, the number of tulips is 12.

The shorter leg of a right triangle is two less than the hypotenuse. The longer leg is one less than the hypotenuse. Find all th
Marina86 [1]

Answer:

x = 5

Step-by-step explanation:

using the Pythagorean theorem:

(x-1)² + (x-2)² = x²

x²-2x+1 + x²-4x+4 = x²

reduce:

2x²-6x+5 = x²

subtract x² from each side:

x²-6x+5 = 0

(x-1)(x-5) = 0

x=1 but because shorter leg would be 0, a triangle would be impossible.

x=5

Rachel deposited $5,960.32 into a savings account with an interest rate of 4.2% compounded twice a year. About how long will it
ahrayia [7]
You need the compound interest formula solved for time:
Years = log (total / principal) / n * log (1 + rate / n)
Years = log (9,000 / 5,960.32) / 2 * log (1 + .042/2)
Years = log ( <span> <span> <span> 1.509986041</span></span></span>) / 2 * log (1.021)
Years =  0.1789729325 / 2 * 0.0090257420869
Years =  <span> <span> </span></span><span><span><span>0.1789729325 / 0.0180514842 </span> </span> </span>
<span><span><span>Years =  9.9145826746 </span> </span> </span>
the answer is "d"
