Answer:

<u>-2</u>

Step-by-step explanation:

<u>Given</u> :

  • An example of a coefficient ⇒ '11' in 11kk

<u>Solving</u> :

  • The coefficient is the part that precedes the variable(s)
  • Therefore, on solving -k - k
  • ⇒ -2k
  • ⇒ <u>-2 is the coefficient</u>

Answer:

-2

Step-by-step explanation:

Given expression: -k - k

<u>Combine like terms and simplify:</u>

⇒ -k - k

⇒ -(k + k)

⇒ -(2k) = -2k

<u>Determining the constant:</u>

The constant of the term MUST be an integer. It CANNOT be a variable. In this case, the only constant that is a cooeficient of k is -2.

Thus, the cooeficient of -k−k is -2.

The Apollo's chariot, a rollercoaster at Busch gardens, moves at 110 feet per second. The equation of the ride can be represente
GREYUIT [131]

Answer:

169.39 feet.

Step-by-step explanation:

We have been given that the Apollo's chariot, a roller coaster at Busch gardens, moves at 110 feet per second. The equation of the ride can be represented by the equation h(t)=-16t^2+101t+10. We are asked to find the maximum height that the ride can reach.

To  find the maximum height that the ride can reach, we need to find y-coordinate of vertex of parabola because our given equation is downward opening parabola and its maximum point will be the vertex.

First of all, we will find x-coordinate of vertex using formula \frac{-b}{2a}.

\frac{-101}{2(-16)}=\frac{101}{32}=3.15625

Now, we will substitute t=3.15625 in our equation to find y-coordinate of vertex as:

h(3.15625)=-16(3.15625)^2+101(3.15625)+10

h(3.15625)=-16(9.9619140625)+101(3.15625)+10

h(3.15625)=-159.390625+318.78125+10

h(3.15625)=169.390625

h(3.15625)\approx 169.39

Therefore, the ride will reach to a maximum height of 169.39 feet.169.39 feet.

What is x when tan24 = 5/x
kirill115 [55]

Answer:

x ≈ 11.23

Step-by-step explanation:

Given

tan24° = \frac{5}{x} ( multiply both sides by x )

x × tan24° = 5 ( divide both sides by tan24° )

x = \frac{5}{tan24} ≈ 11.23 ( to 2 dec. places )
