Answer:
<h2>I don't no answer sorry sorry</h2>
Given:
A deep sea diver started at sea level (0 feet).
Rate of diving = 5.6 feet per minute.
Time =
hour
To find:
The rational number that represents his position relative to sea level.
Solution:
We know that,
1 hour = 60 minutes
hour = 30 minutes
A deep sea diver, dove at a rate of 5.6 feet per minute.
Distance covered in 1 minute = 5.6 feet
Distance covered in 30 minute = 30 × 5.6 feet
= 168 feet
The diver dove 168 feet in
hour. Since it is below the sea level, therefore it should be negative.
So, the rational number that represents his position relative to sea level is
feet.
Therefore, the correct option is D.
Answer:
The value has increased by <u>8 percent</u>.
Step-by-step explanation:
Given:
The value of a house has increased by $4,200 in the past year.
The value last year was $52,500.
Now, to find the percent increased.
<em>Value of house = $52,500.</em>
<em>Value of house last year increased by = $4200.</em>
So, to get the percent increased:
![\frac{Value\ of\ house\ last\ year\ increased\ by} {Value\ of\ house}\times 100.](https://tex.z-dn.net/?f=%5Cfrac%7BValue%5C%20of%5C%20house%5C%20last%5C%20year%5C%20increased%5C%20by%7D%20%7BValue%5C%20of%5C%20house%7D%5Ctimes%20100.)
![=\frac{4200}{52500} \times 100](https://tex.z-dn.net/?f=%3D%5Cfrac%7B4200%7D%7B52500%7D%20%5Ctimes%20100)
![=0.08\times 100](https://tex.z-dn.net/?f=%3D0.08%5Ctimes%20100)
![=8\ percent.](https://tex.z-dn.net/?f=%3D8%5C%20percent.)
Therefore, the value has increased by 8 percent.
Answer:
26
Step-by-step explanation:
the function is f(x), and we need to find f(-2). the only difference between the two terms i gave is the -2 replacing the x. this means that you must replace every x in the first equation with -2. this makes the new function f(-2)=-9(-2)+8. after multiplying the -9 and -2 and adding that product to 8, you come up with your answer: 26.
