Answer:
Please, see the image below.
Step-by-step explanation:
I attached an image of the sketched region below.
You take into account that y=0 is the x axis.
Furthermore, you take into account that f(x)=-5x^3 is, for x=-2 and x=-1:
f(-2)=40
f(-1)=5
Finally, the region bounded by the equations is above the negative x axis.
Answer:
3/5 is greater because when you convert it into decimal it's 0.6 and when you convert 23% into decimal it's 0.23
1. You have that the series is: <span>5+25+125+625+3125+15625
2. You must find the ratio (r) between the adjacent members. Then, you have:
25/5=5
125/25=5
625/125=5
3125/625=5
15625/3125=5
3. Therefore, the ratio is:
r=5
4. Then, each term has te form 5</span>^k. <span>So, you have:
5</span><span>^1=5
</span> 5<span>^2=25
</span> 5<span>^3=125
</span> 5<span>^4=625
</span> 5<span>^5=3125
</span> 5<span>^6=15625
5. As you can see, "k" goes from 1 to 6.
6. The answer is shown in the image attached.</span>
Answer:
EQUATION IS GIVEN BELOW.
Step-by-step explanation:
let the number be 'x'
now,
x+12 =36
or, x=36-12
therefore,x=24
Answer:
y=120-4x
Step-by-step explanation:
Here we are given the average speed for Day 1 and Day 2 and the time of ride . We asked to Find an expression to determine the total distance travelled in two days.
Day 1 :
Avg Speed = 8 mph
Let the time for travelling = x hrs
Hence Distace Travelled D1= Speed x Time
D1=8x
Day 2 :
Avg Speed = 12 mph
Total time of travelling for two days is given as 10 hours . Hence the time of travelling for day 2 is
= (10-x) hrs
Hence Distance travelled in Day 2 D2 = speed x time
D2 = 12(10-x)
D2=120-12x
Total Distance travelled = D1 + D2
= 8x+120-12x
=120-4x
If the total distance travelled is denoted by y
The expression will be
y=120-4x
