Answer:
x=-3,x=9
Step-by-step explanation:
x^2-6x-20-7=0
x^2-6x-27=0
x^2-(9-3)x-27=0
x^2-9x+3x-27=0
x(x-9)+3(x-9)=0
(x+3)(x-9)=0
x=-3,x=9
Answer:
I can say Now it's a positive fuction so the answer choices B and D with the negative 1 is wrong, sense Y is = 0 since the slope goes through 0
Step-by-step explanation:
My guess is Most likely <u><em>A </em></u>Since C The slope is going left to right which is positive
Answer:
B.
Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
As given in the question, we know that:
The ratio of the area of the circle to the area of the square is π/4
- The formula to find the volume of the cone is:
V = 1/3*the height*the base area
<=> V1 = 1/3*h*π
- The formula to find the volume of the pyramid is:
V2 = 1/3*the height*the base area
<=> V = 1/3*h*4
=> the ratio of volume of the cone to the pyramid is:
= 
= (1/3*h*π
) / ( 1/3*h*4
)
= π/4
S we can conclude that the volume of the cone equals π/4 the volume of the pyramid
Hope it will find you well.
(y2-y1)/(x2-x1) (-3 - (-8))/(6- (-5))= 5/11
If you want to make it so that you work most of the hours on the first 4 days, you should work 5 hours. 5*4=20, so 1 hour would be left over on the 5th day.
