What is the y-intercept of the function described in the table?

lord [1]

Answer:

the y-intercept is 2.

Step-by-step explanation:

If you find the rate of change, which in this case is 1/-4, you can reverse the rate of change.

1 and -2

-1 (instead of adding 1) to x

+4 (instead of subtracting) to y

you get (0, 2).

Making the y-intercept 2.

Question 3 / 5

Allisa [31]

There are 10 seats in ferris wheel of love.

One couple can fit in to one seat. That means 1 couple per seat.

Given, in each minute a seat passes by the entrance or exit stage. That means one couple can use the seat for one minute. That means 1 seat per minute.

The wheel starts functioning at 8 p.m for half an hour. In 1 hour there are 60 minutes. So half an hour means $\frac{60}{2}$ = 30 minutes.

So we have got 1 couple per seat and 1 seat per minute. If we multiply them we will get 1 couple per minute.

We have got in 1 minute there is 1 couple.

So in 30 minutes there are $(1)(30)$ couples = 30 couples.

We have got the required answer here.

There are 30 couples who took a ride in the ferris wheel of love.

Given that log 2 = 0.3010 and log 3 = 0.4771 , how can we find log 6 ?

bearhunter [10]

Answer:

$\sf \log_{10}6=0.7781$

Step-by-step explanation:

<u>Given</u>:

$\sf \log_{10} 2 = 0.3010$

$\sf \log_{10} 3 = 0.4771$

To find log₁₀ 6, first rewrite 6 as 3 · 2:

$\sf \implies \log_{10}6=\log_{10}(3 \cdot 2)$

$\textsf{Apply the log product law}: \quad \log_axy=\log_ax + \log_ay$

$\implies \sf \log_{10}(3 \cdot 2)=\log_{10}3+\log_{10}2$

Substituting the given values for log₁₀ 3 and log₁₀ 2:

$\begin{aligned} \sf \implies \log_{10}3+\log_{10}2 & = \sf 0.4771+0.3010\\ & = \sf 0.7781 \end{aligned}$

Therefore:

$\sf \log_{10}6=0.7781$
