Answer:

0.1 , 0.2 , 0.05

Step-by-step explanation:

*each column adds to 1*

20 x 1/2 = 10

1/2 x 20 x 0.1 = 1

top left box = 0.1

; 5 x 2 x 0.1 = 1

1/2 x 10 = 5

; 0.2 x 1/2 x 10 = 1

bottom middle box = 0.2

; 5 x 1 x 0.2 = 1

; 2 x 10 x 0.05 = 1

middle right box  = 0.05

; 20 x 1 x 0.05

What is the distance between the points (21,-30) and (3,8)
Scilla [17]

Answer:

approximately 42.05

Step-by-step explanation:

We know that the distance formula is \sqrt{(x_{2}-x_{1})^{2} +(y_{2}-y_{1})^{2} }, so if we use (3,8) as point 2 and (21, -30) as point 1 (note that these are interchangeable), we know that

x₂=3

y₂=8

x₁=21

y₁=-30

Then, we can plug it into the formula to get \sqrt{(3-21)^{2} +(8-(-30))^{2 }} = \sqrt{18^{2}+38^{2}}=sqrt{1769}= 42.05 (approximately)

Please help me . I need help with this. I’m getting very very frustrated !!! You can get 35 points !
Elden [556K]

Notes:

  • The sign of the coefficient of the quadratic equation determines if the vertex is a minimum or maximum.  Positive looks like ∪ so has a minimum.  Negative looks like ∩ so has a maximum.
  • Maximum/minimum height is the y-value of the vertex.
  • Time to reach maximum height is the x-value of the vertex (which is also the Axis-Of-Symmetry).

Answer:  4) maximum

               5) 20.1 ft

               6) 2 seconds

<u>Step-by-step explanation:</u>

4) h(t) = -16t² + 256t

            ↓

            the coefficient is negative so it looks like ∩.  

            Therefore, it has a maximum.

5) h(t) = -16t² + 30t + 6

\text{AOS: }x=\dfrac{-b}{2a}\quad \rightarrow \quad x=\dfrac{-(30)}{2(-16)}=\dfrac{-30}{-32}=\dfrac{15}{16}\\\\\\\text{Maximum: }h\bigg(\dfrac{15}{16}\bigg)=-16\bigg(\dfrac{15}{16}\bigg)^2+30\bigg(\dfrac{15}{16}\bigg)+6\\\\\\.\qquad \qquad \qquad \qquad =\dfrac{-225}{16}+\dfrac{450}{16}+\dfrac{96}{16}\\\\\\.\qquad \qquad \qquad \qquad =\dfrac{321}{16}\\\\\\.\qquad \qquad \qquad \qquad \approx20.1

6) h(t)=-16t²+64t+80

\text{AOS: }x=\dfrac{-b}{2a}\quad \rightarrow \quad x=\dfrac{-(64)}{2(-16)}=\dfrac{-64}{-32}=2
