Answer:

(52 + 4 - 6) - (-52 - 3 + 15) = 90

Step-by-step explanation:

To solve:

(52 + 4 - 6) - (-52 - 3 + 15)

Let's attack the question step after step and be mindful of our signs

BODMAS will be our giude. It means we will solve :

BRACKETS first

DIVISION

MULTIPLICATION

ADDITION

SUBTRACTION.

Anyway, addition and subtraction can he overlapped.

Let's go now!

(52 + 4 - 6) - (-52 - 3 + 15)

=(56 - 6 ) - ( -55 + 15)

=(50) - ( -40)

We will have to open the brackets at this point and be very careful of the signs

= 50 - * - 40

= 50 + 40

= 90

Let's keep learning!

Maths is fun

Answer:

Step-by-step explanation:

make sure to use BIDMAS

start of by working out everything in the brakets first.

the first bracket would be 50

the second bracket would be -40

the minus these as there is a minus between the brackets

50--40=90

The formula for compound interest is:

sveta [45]

Answer:

Future value, A = $642

Step-by-step explanation:

Given the following data;

Principal = $500

Interest rate = 5% = 5/100 = 0.05

Time, t = 5 years

n = 365

To find the future value, we would use the compound interest formula;

$A = P(1 + \frac{r}{n})^{nt}$

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

$A = 500(1 + \frac{0.05}{365})^{365*5}$

$A = 500(1 + 0.000137)^{1825}$

$A = 500(1.000137)^{1825}$

$A = 500*1.2840$

Future value, A = $642

Answer:

P=1620

Third option

Step-by-step explanation:

Horizontal Asymptotes

A given function is said to have a horizontal asymptote in y=a, if:

$\displaystyle \lim _{x\rightarrow -\infty }f(x)=a$

Or,

$\displaystyle \lim _{x\rightarrow +\infty }f(x)=a$

For the given function, the population of the species of bird is given by :

$\displaystyle p(t)=\frac{1620}{1+1.15e^{-0.042t}}$

Where t is the time in years. To find the horizontal asymptote, we should compute both limits to check if they exist.

$\displaystyle \lim _{x\rightarrow +\infty }\frac{1620}{1+1.15e^{-0.042t}}=\frac{1620}{1+0}=1620$

When t tends to plus infinity, P tends to 1620 .

The second asymptote is computed by:

$\displaystyle \lim _{x\rightarrow -\infty }\frac{1620}{1+1.15e^{-0.042t}}=\frac{1620}{1+\infty}=0$

When t tends to minus infinity, P tends to zero. Since the domain of P is $t\geq 0$ , this asymptote is not valid, thus our only asymptote is

$\boxed{P=1620}$

3(r-6)+2=4(r+2)-21 find the value of x and show steps

MAXImum [283]

3(r-6) +2 = 4(r+2) -21
3r - 6r +2 = 4r +8 -21
-3r +2 = 4r -13
2 = 7r -13
15 = 7r
r = $\frac{15}{2}$
r = 7.5

Which linear function has the steepest slope?

Aneli [31]

Answer:

the graph... it's slope is |2| and the chart is |1|

the absolute values are there because the questions only says "how steep"

not the direction
