If the simple interest on ​$6,000 for 2 years is ​$840​, then what is the interest​ rate?
ankoles [38]

Answer:

7 %

Step-by-step explanation:

  • i do not know if you use this but I use S.I=P×R/100×T
  • S.I=840
  • P for principal(the money you borrow or lend) =6000
  • T for time=2 years.
  • R for rate=???
  • In order to find out the rate, you need to substitute all these numbers into their respective places.
  • 840=6000×r/100×2
  • 6000/100=60
  • 840=60×r×2
  • 840=120r
  • r=7%

Question: Find the vertex.<br><br> Equation: y = -x^2-6x+15<br><br> ([Put Number],[Put Number])
Artyom0805 [142]

Answer:

y = (x - 3)² + 6

Step-by-step explanation:

the equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

Using the method of completing the square

y = x² - 6x + 15

add/subtract ( half the coefficient of the x- term )² to x² - 6x

y = x² + 2(- 3)x + 9 - 9 + 15

y = (x - 3)² - 9 + 15

y = (x - 3)² + 6 ← in vertex form

I need help I do not understand this it's due tomorrow
Goshia [24]
I'll help you out with 3 questions.
For #1, you kind of figured it out yourself
That 90 degree angle on paper means that m/1 and m/2 make up 90
If m1 is 50, then just subtract m1 (50) from 90, making it 40. m/2 is 40

If Angle M4 is 45 degrees then angle M3 is 180-45 since they both make up a 180 degree angle.

There are 180 degrees in a triangle
If m 8 = 78
and m 9 = 60 
m 10 is 180 - 78 - 60
