Bogdan [553]

Answer: 7 hr

Step-by-step explanation:

Given

Distance between Emily and Kylie is $140\ \text{miles}$

Speed of Emily $v_e=12\ mph$

Speed of Kylie $v_k=8\ mph$

Distance traveled by Emily $\Rightarrow d_e=12t$

Distance traveled by Kylie $\Rightarrow d_k=8t$

$\Rightarrow 12t+8t=140\\\Rightarrow 20t=140\\\Rightarrow t=7\ hr$

They will meet after 7 hour.

Find the values of A, B, and C in the table.

PilotLPTM [1.2K]

Answer:

A = 1

B = 2

C = below

Step-by-step explanation:

Zero is included in the second interval, therefore, A = 1 is a correct choice (A must be also less than 2 ).

B must be positive, so that, f(0) is above the x-axis, therefore, B = 2 is a correct choice.

f(1.5) is negative, this means that the function is <u>below</u> the x-axis, then, C = below.
