4 lemons are bought for Rs10 and sold 3 Rs10 what is the profit? ​

Answer:

[tex]A(-1,-8)[/tex]

Step-by-step explanation:

Given

Point: A(2,6)

Translation: 1 left and 3 up

Rotation: 180 degrees

Required

Image of Point A

Taking the exercise one after the other

Represent the function as: (x,y)

Such that

[tex]A(x,y) = A(2,6)[/tex]

1 unit left translation means the function becomes (x - 1, y)

2 unit up translation means the function becomes (x - 1, y + 2)

Applying the above transformation

[tex]A(2,6) -> A(2-1,6+2)[/tex]

[tex]A(2,6) -> A(1,8)[/tex]

At this stage, the coordinate becomes

[tex]A(1,8)[/tex]

When a function (x,y) is rotated by 180, the new function becomes (-x,-y)

So;

The further transformation of A is

[tex]A(1,8) -> A(-1,-8)[/tex]

Hence, the new image of A is

[tex]A(-1,-8)[/tex]

Answer:

D(t) = 50 -2t

At 25 seconds, the dog caught up with the cat

Step-by-step explanation:

At initial time t0

Distance = 50 ft

The dog is running 12 feet per second and the cat is running 10 feet per second.

So for each each time in seconds

Dog covers 12 feet while cat extends by 10 ft .

The distance between them at any given time

D(t)= 50 +10t -12t

D(t) = 50 -2t

The time it will take the dig to get to the cat is what D= 0

D(t) = 50 -2t

0= 50- 2t

2t= 50

t= 25

So at 25 seconds, the dog caught up with the cat

Answer:

Falling

Step-by-step explanation:

You have to convert it into slope-intercept form(y=mx+b) to find out. TO do this, you subtract 4x from the left, so it would be y=-4x-3. -4x is the slope, and since it is negative, it is falling.

Answer:

Answer:

-3 and 4

Step-by-step explanation:

We can start naming the first number x

Hence, the second number would be 10+2x

Set up an equation.

10+2x+x=1

Combine like terms

10+3x=1

Subtract 10 from both sides

3x=-9

Divide both sides by 3.

x=-3

The first number is he first is -3.

Plug that into the expression for the second number.

10+2x

10+2(-3)

10-6

4

The two numbers are -3 and 4.

Answer:

69

Step-by-step explanation:

If she is averaging 65% of the worth of lectures.

the lectures she had was supposedly rated out of 60. Therefore, the 65% will be 65% of 60(total grade)

0.65 * 60 = 39

On the second part, if we apply the same method, we have

0.75 * 40 = 30

All we have to do on add both together

39 + 30 = 69.

therefore, get total grade in the course is 69

Total grade in the course is 69%

Since,  the averaging 65% of the points in lecture is worth to 60% of total grade.

It means that, the 65% will be equivalent to,

                  [tex]=\frac{60*65}{100}=3900/100=39[/tex] percent of total grade.

And 75% in lab is worth 40% of total grade.

             [tex]=\frac{75*40}{100}=30[/tex] percent of total grade.

We have to add both together

            [tex]39 + 30 = 69.[/tex]

Thus,  total grade in the course is 69%

Step-by-step explanation:

Initial ratio of maple trees to oak trees

New ratio  of maple trees to oak trees

Number of oak trees = 132

Number of maple trees

Total number of trees

Initial number of maple trees

The difference in the number of maple trees:

Answer:

72 more trees before the bug problem

Step-by-step explanation:

The ratio was 9:5 before the bug problem and 3:11 after.

After the bug problem there were 132 oak trees,

m : 132 = 3 : 11

Then we know

m/132 = 3/11

Multiplying both sides by 132 cancels on the left

132 × (m/132) = (3/11) × 132

m = (3/11) × 132

Then solving for m

m = 132 × (3/11)

m = 36   This gives us the number of trees after the bug problem.

This would give us 168 trees in total, 132 oak, and 36 maple.

Since there is the same number of trees as before we calculate the number of maple and oak previously.

If Shelley counted 9 maple for every 5 oak we know that 9 out of 14 trees are maple and 5 out of 14 trees are oak.

9/14 = .6428 which is the percentage of maple trees before the bug problem.

We multiply .6428 x 168 (the total number of trees) and we get 108.

if there are 108 maple trees then 168-108 = 60 oak trees.

Further proof:

9:5 or 9/5 = 1.8     108/60 = 1.8

108 maple trees and 60 oak before the bug problem.

So 108 (maple before bug problem) and 36 maple trees after:

108 - 36 = 72 more trees before the bug problem

u = 57.6

Step-by-step explanation:

u/9.6 = 6

Multiply each side by 9.6

u/9.6 * 9.6 = 6* 9.6

u = 57.6

Answer:

u = 57.6

Step-by-step explanation:

To isolate u, we have to multiply 9.6 on both sides to eliminate the denominator. That leaves us with u = 6 * 9.6 = 57.6

Step-by-step explanation:

Because your finish place is mutually exclusive (if you come in first you cant come in second, if you come in second you cant come in third, etc) you have to decrease the amount of runners for each place.

20 runners can get first

19 for second

18 for third

17 for fourth.

To find out the total amount of possibilities you multiply each amount. 20 x 19 x 18 x 17 = 116,280.

Answer: Answer is in the steps

Step-by-step explanation:

using the function h(t) = -16t^2 + 64t + 80    and H is height in feet  t is the time in minutes we can evaluate how high the platform is by solving for the y intercept.

h(t) = -16t^2 + 64t + 80  the y intercept is when h(t) is h(0)  so when it is h of zero  put zero into the function and solve the function

A) -16(o)^2 + 64(0) + 80  

      0 -0  + 80

    h(0) =  80  

Which means the platform is 80 feet high.  

B) In the reading it says that it will set the firework at its highest point  and in other words its highest point is its vertex. So solve for the vertex .

   h(t) = -16t^2 +64t + 80       To solve for the vertex, use the formula x= -b/2a  to find the x coordinate of the vertex.

     so  the value of b is 64  and a is -16 .

 x = -64 / -32    

x = 2

 So the x coordinate of the vertex is 2  so input it and solve for the y coordinate of the vertex.

h(t) = y =  -16(2)^2 + 64t+80

y=   -16(4) + 64(2)+ 80  

  y=   -64 + 128 + 80

      y = 144  

So the y coordinate is 144. which means the vertex  is (2,144) and also means that the fireworks will be released at  a 144 feet.

 C)  The drone will land on the ground when they is not height which means when  y is equal to zero or h(t)  is zero.  

          -16t^2 +64t + 80 = 0       so solve for t using the quadratic formula.

The quadratic formula says that  x= -b ± [tex]\sqrt{b^2 -4ac} /2a[/tex]  

   a = -16     b= 64   and c= 80  

 x = -64 + [tex]\sqrt{9216}/ -32[/tex]  

 x= -64 ± 96 /-32  

  x=  -1   or  x = 5

    Which means the drone land on the ground in 5 minutes. It can't be -1 because a negative number can't represent time.

Answer:

Given series is divergent

Step-by-step explanation:

Step(i):-  

By using Ratio test

                [tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = l[/tex]

a)     [tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = l[/tex]  

'l' is finite then the given ∑aₙ is convergent

b)   [tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = l[/tex]  

Here 'l' is infinite then the  ∑aₙ  is divergent

Step(ii):-

Given      aₙ = [tex]\frac{n!}{n}[/tex]

            [tex]a_{n+1} = \frac{(n+1)!}{n+1}[/tex]

     [tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = \lim_{n \to \infty} |\frac{\frac{(n+1)!}{n+1} }{\frac{n!}{n} } |[/tex]

               we know that  n ! = n (n-1) (n-2) ......3.2.1

              and also          (n+1) ! = (n+1)n!

  [tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = \lim_{n \to \infty} |\frac{\frac{n+1)n!}{n+1} }{\frac{n!}{n} } |[/tex]

[tex]\lim_{n \to \infty} |\frac{a_{n+1} }{a_{n} } | = \lim_{n \to \infty} n[/tex]

                       = ∞
