Answer:

6) -3

7) 32

8) -6.5

Step-by-step explanation:

6) -2 -1 = -3 You add because they are both negatives.

7) You multiply both and it becomes a positive because they are both negatives.

8) -13 ÷ 2 = -6.5

Find the cost of a cd in 6years,assuming an inflation rate if 4% , if its present cost is $11.95

choli [55]

The cost of a cd after 6 year is =$ 15.12

Step-by-step explanation:

The present cost of the cd is $11.95 and inflation rate 4%

P = $11.95 , r = 4% and n = 6 years

The cost of a cd after 6 year is = $P (1+\frac{r}{100})^n$

=$ $11.95(1+\frac{4}{100})^6$

=$ 15.12

Some help with the circle problem would be much aprecated.

Oksana_A [137]

Try this solution:
for the circle A: circumference=6π, area=9π
for the circle B: circumference=12π, area=36π

PS. formula for circumference is 'L=2πr', for area is 'S=πr²'.

Brook makes this conjecture: Because the angles are equal, the proportion of area of each sector relative to the area of the giv

AnnZ [28]

Answer:

The Brooks conjecture is true as the proportion of the area of a sector to the area of a circle is only dependent on the angle.

Step-by-step explanation:

The area of a sector for a radius r and an angle θ is given as

$\Delta Sector=\dfrac{1}{2}r^2\theta$

Whereas the area of a circle for a radius r is given as

$\Delta Circle=\pi r^2$

Now the ratio is given as

$\dfrac{\Delta Sector}{\Delta Circle}=\dfrac{\dfrac{1}{2}r^2\theta}{\pi r^2}$

Here as r is the radius of the circle and it is the same therefore the above ratio is simplified to

$\dfrac{\Delta Sector}{\Delta Circle}=\dfrac{\theta}{2\pi }$

Here as π is constant the only variable here is θ. Thus according to Brooks conjecture when the angles are equal, the proportion of area of each sector relative to the area of the given circle is also equal is true.
