Answer:

Step-by-step explanation:

This is an arithmetic sequence, in which a set number is added to the previous term to get the next term. The number added is figured out by subtracting the 1st term from the 2nd term and the 2nd term from the 3rd term.

Now that we know the number is 3, we can complete the sequence:

4, 7, 10, 13, 16, 19, 22

We will add all the terms up to get 91.

Answer:

true

Step-by-step explanation:

The given statement AB+BC=AC, then AB=BC​ is false for the line segment.

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

If AC is the line segment and B is in between AC  somewhere then the given statement AB+BC=AC, then AB=BC​ is not necessarily true.

As the two diagrams below;

Diagram 01) →

Here B is the midpoint of  AC so AB = BC

Diagram 02) →

Here B is not the midpoint of AC so AB ≠ BC

Hence "The given statement AB+BC=AC, then AB=BC​ is false for the line segment".

Answer:

Q7) ( 2,-2)

Q8) (- 0.5 , -2)

Step-by-step explanation:

As we have to find the mid-points of the line segments, the line segments will be divided in same ratio i.e. 1:1 (∵ A Mid-point divides a line segment into equal parts )

According to Section formula ,

[tex]( x' , y') = (\frac{mx^2 + nx^1}{m+n} , \frac{my^2+ny^1}{m+n} )[/tex]

where (m,n) are the ratios in which a line segment is divided & ( x¹ , y¹ ) ( x², y²) are the co-ordinates of a line segment.

In Q7 ,

x¹ = 3 , y¹ = -9 , x² = 1 , y² = 5 & m = n = 1

So putting the section formula here gives :-

[tex]( x' , y') = (\frac{1*1 + 1*3}{1+1} , \frac{1*5+1*(-9)}{1+1} ) = ( 2 , -2)[/tex]

In Q8 ,

x¹ = 5 , y¹ = -1 , x² = -6 , y² = -3

So putting the section formula here gives :-

[tex](x' , y') = (\frac{1*(-6) + 1*5}{1+1} , \frac{1*(-3) + 1*(-1)}{1+1}) = ( -0.5 , -2)[/tex]

Step-by-step explanation:

Q3

(a) If 0 < |x − 1| < δ, then |f(x) − 2| < 2

What this means is, how far can x stray from the x=1 line such that f(x) stays within 2 units of the y=2 line (0 < f(x) < 4).

If we move 2 units left of x=1, we get f(x) = 4.

If we move about 3.5 units right of x=1, we get f(x) = 4.

Therefore, δ can't be more than 2.

(b) If 0 < |x| < δ, then |f(x) − 3| < 1

What this means is, how far can x stray from the x=0 line such that f(x) stays within 1 unit of the y=3 line (2 < f(x) < 4).

If we move 1 unit left of x=0, we get f(x) = 4.

If we move 1 unts right of x=0, we get f(x) = 2.

Therefore, δ can't be more than 1.

Since f(x) isn't continuous within this domain, we can't conclude that the limit exists.

Q4

(a) Yes.  If δ = 0.25, then 0.75 < x < 1.25, and f(x) > 200.

(b) No.  f(1) = 300, so even if δ = 0, f(x) will be less than 400.

(c) Yes.  If δ ≈ 0.1, then 0.9 < x < 1, and f(x) > 450.

Answer: Choice A) $0.20

=======================================================

Explanation:

The store bought the batch for $100, and sold that same batch for $150. The profit of the entire batch is 150-100 = 50 dollars.

Divide this over 250 to get 50/250 = 0.20 dollars.

Their profit is $0.20 per pastry (ie 20 cents per pastry).

-------

You can think of it like this

50 dollar profit = 250 pastries

50/250 dollar profit = 250/250 pastries (dividing both sides by 250)

0.20 dollar profit = 1 pastry

That last equation tells us one pastry yields a profit of $0.20 or 20 cents.

Answer:

$0.20

Step-by-step explanation:

If the purchased is $100 for 250 pastries, then 1 ipastry at purchase is:

$100=250

    ?  = 1

1×100/250 = $0.40 ( at purchase)

Then when resold, the profit is:

if 250 pastries= $150

1 pastry=?

$150× 1/ 250= $0.60

s0, the profit will be $0.60 - $0.40 = $0.20

$0.60 per hour
