Answer:

k = 2

Step-by-step explanation:

We'll need the Midpoint Formula:  the midpoint of a segment joining points [tex](x_1, y_1) \text{ and }(x_2, y_2) \text{ is } \left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right)[/tex].  In other words, average the x's, then average the y's.

The midpoint of a diameter is the centre of the circle!

The midpoint of the segment joining (-3, 2k) and (5, k) is

[tex]\left(\frac{-3+5}{2}, \frac{2k+k}{2} \right)=\left(1,\frac{2k+k}{2}\right)=\left(1,\frac{3k}{2}\right)[/tex]

That last expression is the centre of the circle; it is the same as (1, 3).

[tex]\left(1,\frac{3k}{2}\right)=\left(1,3\right)\\\frac{3k}{2}=3\\3k=6\\k=2[/tex]

Step-by-step explanation:

1. We have to divide 4200 by a number which is a multiple of 10.

Let us assume that the number is 20, which is a multiple of 10.

Now, after division the quotient will be .

2. We have to check whether the quotient is multiple of 10 or not.

Here, the quotient is 210 which is a multiple of 10.

Hence, the required number which is a multiple of 10 is 20.

Answer:

3.46grams

Step-by-step explanation:

100coins = 346grams

1 coin = xgrams

then we cross multiply

346 = 100x

therefore x= 3.46grams

Answer:

.53

Step-by-step explanation:

divide 8 by 15 and you get 0.53 explanation As a decimal 8/15 is 0.533 (3 repeating) or about 0.53. To convert 8/15 into a decimal value we simply divide 8 by 15. Since 15 cannot be divided into 8 we add a decimal and a zero then divide 15 into 8, giving us 5 with 5 remaining. Adding another zero allows us to divide 15 into 50 3-times with 5 remaining.

Answer:

D

Step-by-step explanation:

1. Add the costs together 10.98+13.95+22.56=47.49

2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.

47.49/3=15.83

The option closest to our number is D so we round up.

$15.83->$20

The maximum area that David can have is  10,000 yd^2

The formula for calculating the area of a rectangle is expressed as:

A = lw

If David has 400 yards of fencing, then;

P = 2(l +w)

400 = 2( l+ w)

200 = l + w

l = 200 - w

Substitute into the area

A = (200-w)w

A = 200w - w^2

If the area is maximized, then;

dA/dw = 0
dA/dw = 200 - 2w

2w =200

w =  100 yards

Recall that;

200 = l + w

l = 200 - 100

l = 100

The maximum area = 100 * 100

The maximum area = 10,000 yd^2

b) The temperature of the water at 5 p.m. would be -2.5 *C

Step-by-step explanation:

A) Adding-10.6 and -8.7 would give you over 19, and this would be more than 16.8. Therefore, we can assume that 16.8- 19 is less than zero

B) -10.6+16.8-8.7=-2.5

Answer:

a)

b) 1/3

c) 1/2

d) 1/2

e) 0

Step-by-step explanation:

a) There are 2 different types of dessert and 3 different ice cream flavors.      

   Therefore, there are 6 possible ice cream orders:

b) There are 2 different desserts with apricot ice cream.

⇒ P(apricot ice cream) = 2/6 = 1/3

c) There are 3 combinations of sundae.

⇒ P(sundae) = 3/6 = 1/2

d) P(chocolate) = 2/6 = 1/3

   P(blackberry waffle cone) = 1/6

⇒ P(choc) OR P(BWC) = 1/3 + 1/6 = 1/2

e) P(orange sherbet) = 0

Answer:

  15/16

Step-by-step explanation:

For the purpose here, we define a starting value as the midpoint of the interval between the integers on either side of the solution. Those integers are 0 and 1, so our starting value for an approximation of x is 1/2.

Each iteration will evaluate the difference f(x)-g(x) at this approximation. If the difference has the sign that matches the difference at the left end of the interval, then the approximation replaces the left end. If the sign matches the difference at the right end, then the approximation replaces the right end. The iteration ends with an approximation that is the midpoint of the new interval.

The attachment shows that our intervals start at [0, 1] and proceed through [1/2, 1], [3/4, 1] to [7/8, 1]. The approximation at the end of the 3rd iteration is x ≈ 15/16.
__

Additional comment

The way this iterative process is defined, the denominator of the n-th approximation will be 2^(n+1). That is, the third iteration will result in a fraction with a denominator of 2^(3+1) = 2^4 = 16, as in 15/16.

As always with repetitive calculations, a graphing calculator or spreadsheet can reduce the work.

Answer:

2325 mL

Step-by-step explanation:

Let x = total volume of the tank. When we fill 4/5 of water into the tank, the amount of water we have can be expressed by 4x/5. Then we only keep 1/3 of that amount (poured away 2/3 of the water), so the amount of water is 4x/15. Thus we set up the equation like this:

4x/15 = 620

4x = 9300

x = 2325

Thus the tank can contain a maximum of 2325 mL.

Answer:

750

Step-by-step explanation:

Given:

discount of 25%

Hasan's equation:  d - 0.25d

Bella's equation: 0.75d

d represents the original price.

0.25d represents the discount.

0.75d represents the discounted price.

Example: 1,000 is the price. d = 1,000

0.25d = 0.25(1000) = 250 this is the discount

0.75d = 0.75(1000) = 750 this is the discounted price

Hassan: d - 0.25d =  1000 - 250 = 750

Bella: 0.75d = 0.75(1000) = 750

It would be 13.3 years till the mass of the sample reached 24 grams.

'A quantity is subject to exponentially decay if it decreases at a rate proportional to its current value.'

According to the given problem,

Let x be the number of years spent,

Initial mass = 40 grams

Final mass = 24 grams

Half-life = 18 years

⇒ 24 = 40 × [tex]0.5^{\frac{x}{18} }[/tex]

⇒ 24/40 = 0.5^[tex]\frac{x}{18}[/tex]

⇒ 3/5 = 0.5^[tex]\frac{x}{18}[/tex]

Taking ln on both sides,

⇒ ln (3/5) = [tex]\frac{x}{18}[/tex] ln 0.5

⇒ ln (3/5) / ln (0.5) = x/18

⇒ x = ( 18 × ln (3/5) ) / ln (0.5)

⇒ x = 13.3 years

Hence, we can conclude that the sample need s 13.3 years to decrease its mass from 40 grams to 24 grams.
