Hi. Please i need help with this . No jokes . I need help with (vii) and (ix)​

Answers

9514 1404 393

Answer:

  (vii)  25/4

  (ix)  -61/6

Step-by-step explanation:

(vii) Once again, we remind you that for ax²+bx+c=0, ...

  α+β = -b/a = -(-7/2) = 7/2 = 3.5

  αβ = c/a = -3/2 = -1.5

Then the desired expression is ...

  α/(β+1) +β/(α+1) = (α² +α +β² +β)/((α+1)(β+1))

  = ((α+β)² -2αβ +(α+β))/(αβ +(α+β) +1)

  = (3.5² -2(-1.5) +3.5)/(-1.5 +3.5 +1) = 18.75/3 = 6.25 = 25/4

__

(ix) α/β +β/α = (α²+β²)/(αβ)

  = ((α+β)² -2αβ)/(αβ) = (3.5² -2(-1.5))/-1.5 = 15.25/-1.5 = -61/6

You have to substitute the x-values into the function :

[tex]f( - 2) = {11}^{ - 2} = \frac{1}{121} [/tex]

[tex]f( - 1) = {11}^{ - 1} = \frac{1}{11} [/tex]

[tex]f(0) = {11}^{0} = 1[/tex]

[tex]f(1) = {11}^{1} = 11[/tex]

In the first week of​ July, a record 1,060 people went to the local swimming pool. In the second​ week, 100 fewer people went to the pool than in the first week. In the third​ week, 140 more people went to the pool than in the second week. In the fourth​ week,146 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four​ weeks?

Answers

Answer: 10%

Step-by-step explanation:

As per given ,

Initial number of people went to pool = 1060

After 4 weeks periods, number of people went to pool = 1060 - 100 +140 -146  ['+' for addition . '-' for decrease]

= 954

The percent decrease in the number of people who went to the pool over these four​ weeks = [tex]\dfrac{1060-954}{1060}\times 100[/tex]

[tex]=\dfrac{106}{1060}\times100\\\\=10\%[/tex]

Hence, the percent decrease in the number of people who went to the pool over these four​ weeks = 10%

A bee flies at 6 feet Per second directly to a flower bed from its hive. The bee stays at the flower bed for 19 minutes, and then flies directly back to the hive at 4 ft per second. Is away from the high for a total of 24 minutes. What equation can used to find the distance of the flower bed from the hive? How far is the flower bed from the hive?

Answers

Answer:

720 feet

Step-by-step explanation:

We can Find the travelling time. We know that the bee spends 19 minutes hunting down the nectar in the flowerbed. But was away from the hive for a total of 24 minutes, then the travelling time becomes(24min - 19min) = 5 min

Then let us Convert to seconds vfir consistency

1 minute = 60 seconds

5 minutes = (5×60 )= 300 seconds.

Then the travelling time becomes 300 seconds

We can Find the time each way, since we know that the total time is 300 seconds, though not evenly divided

Let us denote the time there = t

the time back = (300 - t)

But the distances are the same.

r = 6 m/s and r1 = 4 m/s

t1 = t and t2 = (300 - t)

Let dthere = dback

Where, d =( rate × time)

(6× t )= 4 (300 - t)

6t= 1200 - 4t

10t=1200

t=120 seconds

To Find the distance?

d =( rate × time)

d = ? r = 6 m/s and t = 120 second

d = r*t

d = 6 × 120

= 720 feet

Hence, instance of the flower bed from the hive is 720 feet while the equation is ( d = r*t)

Answer:

The graph of f is shifted 6 units up to create the graph of g

Option A is correct option.

Step-by-step explanation:

We are given f(x)=x

and g(x)=f(x)+6

We need to find how f(x) and g(x) are related.

We know that according to translation rules:

if we have f(x) as original graph and f(x)+d as translated graph it means the original graph f(x) is shifted d units up.

So, in our case f(x)=x

g(x)=f(x)+6

The graph of f is shifted 6 units up to create the graph of g

Option A is correct option.

The scale on a map is 1 cm equals 10 miles. Find the length on the map of 300 miles, 150 miles, 60 miles, and 170 miles. List your answers in numerical order.

Answers

Answer:

30 cm = 300 miles

15 cm = 150 miles

6 cm = 60 miles

17 cm = 170 miles

The length of maps of 300miles, 150 miles,170mile and  60 miles are 30cm ,15cm, 17cm and 6cm respectively.

What is unit conversion?

A method of converting from one unit to another.

According to the given question we have

1cm = 10miles

⇒ 1mile = [tex]\frac{1}{10} cm[/tex] = 0.1cm

Therefore, the length on map of

300 miles = 300 × 0.1 = 30cm150 miles = 150 × 0.1 = 15cm170 miles = 170 × 0.1 = 17cm 60 miles  = 60 × 0.1 = 6cm

There are 130 people in a sport centre. 61 people use the gym.

68 people use the swimming pool.

60 people use the track.

25 people use the gym and the pool.

30 people use the pool and the track.

19 people use the gym and the track.

6 people use all three facilities.

Given that a randomly selected person uses the gym and the track, what is the probability they do not use the swimming pool?

Answers

Step-by-step explanation:

Number of people who uses the gym and the track, and also uses the pool = Number of people who use all 3 facilities = 6. (given)

Number of people who uses the gym and the track, and may or may not use the pool = 19. (given)

Therefore number of people who use the gym and track, but do not use the pool = 19 - 6 = 13.

Probability = (13/19) * 100% = 68.4%.
