At your job, you make $8 per hour, and are promised to get a $0.03 per month. Your friend makes $8.15, and is promised a $0.02 r
Rudik [331]

Answer:

3883.2 dollars.

Step-by-step explanation:

We must analyze the situation of each one,

The first tells us to earn 8 dollars an hour, he is promised to receive 0.03 dollars per month, which means that he would already have that increase that month. Therefore, you would have 8.03 per hour of earnings.

The second, on the other hand, although he earns $ 8.15 per hour, the increase is promised every month, that is, it is NO month with the increase of 0.02.

Now assuming they work 8 hours a day and 30 days a month, it would be a total of 8 * 30 = 240 hours.

Now multiplying your hourly income, we will get what each person earns per month.

8.03 * 240 = 1927.2 dollars

8.15 * 240 = 1956 dollars

Which means that both will earn a total of:

1927.2 + 1956 = 3883.2 dollars.

At which root does the graph of f(x) = (x + 4) 6(x + 7)5 cross the x-axis?<br> 0 -7<br> ООО
Maslowich

the root for which the graph of f(x) = (x+4)^{6}(x+7)^{5} cross the x-axis i.e. value of y or f(x) = 0 is x = -7  .

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

We have , f(x) = (x + 4) 6(x + 7)5 i.e.f(x) = (x+4)^{6}(x+7)^{5}. We need to find root for which the graph of f(x) = (x+4)^{6}(x+7)^{5} cross the x-axis i.e. value of y or f(x) = 0. Let's solve this:

⇒ f(x) = (x+4)^{6}(x+7)^{5}

⇒ 0 = (x+4)^{6}(x+7)^{5}

⇒ (x+4)^{6}(x+7)^{5} = 0

Which means either x+4 = 0\\x = -4 or , x+7=0\\x=-7 . That means the root for which the graph of f(x) = (x+4)^{6}(x+7)^{5} cross the x-axis i.e. value of y or f(x) = 0 is x= -4 or x = -7 . ∴ From given options , the root for which the graph of f(x) = (x+4)^{6}(x+7)^{5} cross the x-axis i.e. value of y or f(x) = 0 is x = -7  .
