What is the inverse quadratic function?

Answers

It's called the swapping of domain and range. Even without solving for the inverse function just yet, I can easily identify its domain and range using the information from the graph of the original function: domain is x ≥ 2 and range is y ≥ 0.

Every morning, Jim goes for a morning walk. His normal walking speed is 3 1/2 km per hour, and he walks a total distance of 10 km every day. How much time does he take to cover one km?

Hint 1 Notice the unit of Speed.

Hint 2 Can you figure out the distance covered in one hour​

Answers

Answer:

Jim's walking speed = 312kmph

covered distance = 10km

time taken for one hour = ?

we know that: Distance =speed × time

=>Time = Distance/speed

=> Time = 10/312=5/156 hours

= Time = (5×60)/156=300/156=75/39=1.9 minutes

Answer:

Step-by-step explanation:

subtract 10 to the 25 so that cancels out the 10, you are left with -5m=15, then you divide the -5m by -5 to cancel it out on both sides. that leaves you with m by itself and once you do the division of 15 by -5 the result is -3

Answer: One solution!!

I checked desmos and it only intersected at one point :)

Answer: The answer is ONE Solution

Step-by-step explanation:

A system of equations have no solution when their slopes are the same but they have different y-intercepts. When graphed, the lines cannot intersect for there to be a solution. Looking at both equations, they have different slopes and different y intercepts so you can rule "NO solution" out.

Secondly a system of equations have infinitely many solution if they both share the same slopes and y-intercepts.

Looking at both lines, they have different slopes and different y-intercepts, so you can also rule that out.

A system of equations have one solution if their slopes are different and y intercepts are also different. Looking at the two lines, we can notice that the slope and y-intercepts are all different.

Henry constructed circle A with a radius of 4 units. He then created a sector
as shown in the figure below. Which of the following expressions would help
him find the area of the shaded sector?

Answers

Answer:

C

Step-by-step explanation:

area of circle is found by [tex]\pi[/tex][tex]r^{2}[/tex]

r=4 so 4*4=16

so A=16[tex]\pi[/tex]

we are finding area of shaded part so 45/360(16[tex]\pi[/tex])

The area of the shaded sector is (45/360)16π square units if Henry constructed circle A with a radius of 4 units option (C) is correct.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

Henry constructed circle A with a radius of 4 units.

Henry then created a sector as shown in the figure below.

As we know, the area of the sector can be find using the formula:

Area of the sector = (θ/360)πr²

Here, θ is the central angle

r is the radius

π = 3.141

r = 4 units

θ = 45 degrees

A = (45/360)π(4)²

A = (45/360)16π square units

Thus, the area of the shaded sector is (45/360)16π square units if Henry constructed circle A with a radius of 4 units option (C) is correct.

I believe the constant rate is 13

Step-by-step explanation:

I believe this because for each time you divided y/x you will get 13. But in the last one (146/12) it will be 12.16...  So it will show a constant rate if you round the answer of (146/12) but if you aren't supposed to round then there wont be a constant.

A farmer collects 8 bushels of apples. Each bushel contains 126 apples. If she sells 2 and 1/2 bushels to a local store, how many apples does she have left?

Please help!

Answers

The farmer has 819 apples left

Answer:

693 apples

Step-by-step explanation:

126 x 8 = 1,008

1,008 - 126 (1 bushel) = 882

1,008 - 126 (another bushel) = 756

126/2 = 63

756 - 63 (1/2 bushel) = 693

sorry, the correct answer is 693 apples left

The mean length of 9 childrens' big finger is 6.8cm.
The mean length of 3 adults' big finger is 11cm.
What is the mean length (rounded to 2 DP) of these 12 people's big finger?

Answers

Answer:

The mean length of these 12 people's big finger is of 7.85 cm.

Step-by-step explanation:

Mean value:

Sum of the values of all observations divided by the number of observations.

In this question:

9 + 3 = 12 total observations

Sum:

[tex]9*6.8 + 3*11 = 94.2[/tex]

So

[tex]M = \frac{94.2}{12} = 7.85[/tex]

The mean length of these 12 people's big finger is of 7.85 cm.

Answer:

B, C, E, and F

Step-by-step explanation:

Recall the acronym for trigonometric functions: SOHCAHTOA

Thus:

B = 180 - (48 + 90) = 42°

Let's find the trigonometric functions using 42° as the reference angle:

Opp = b

Hyp = c

Adj = a

Applying SOH:

Sin 42 = opp/hyp

✅Sin 42 = b/c (option C is correct)

Applying CAH:

Cos 42 = adj/hyp

✅Cos 42 = a/c (option A is incorrect)

Applying TOA:

Tan 42 = opp/adj

✅Tan 42 = b/a (option E is correct)

Using 48° as reference angle:

Opp = a

Hyp = c

Adj = b

Applying SOH:

Sin 48 = opp/hyp

✅Sin 48 = a/c (option D is incorrect)

Applying CAH:

Cos 48 = adj/hyp

✅Cos 48 = b/c (option B is correct)

Applying TOA:

Tan 48 = opp/adj

✅Tan 48 = a/b (option F is correct)

A shirt costs 20$ if it was on sale for 75 percent off what is the discount

Answers

You could do x/20 =75/100 and then cross multiply
Then you would have 100x=75*20 and if you simplify all the way you would get x=15
So the discount would be $15

Hope this helps :)
if the shirt cost $20 before discount:
convert 75% to decimal- so divide by 100; you will get 0.75
then you multiply 20 and 0.75
20 x 0.75 = 15
answer: the discount is $15
(however, remember that the new shirt price would be $5)

if the shirt cost $20 after discount:
we know that 100% is the whole, and 75% is the discount, so this means that the leftover 25% = $20
so using proportions,
25/100=20/x, cross multiply & simplify you would get x = 80
to find the discount, subtract the cost from the original price and get 60
answer: the discount was $60
(however remember the original price of the shirt was $80)
