The algebraic expression for “0.8 more than c times 10” is 10c+0.8

Step-by-step explanation:

We need to write an algebraic expression for “0.8 more than c times 10”

Translating the expression in algebraic form:

c times 10 means : 10c

0.8 more than c times 10: More is translated into +

so, 10c+0.8

The algebraic expression for “0.8 more than c times 10” is 10c+0.8

Let's find out the gradient (Slope " m ") of line q ;

$\qquad \sf \dashrightarrow \:m = \dfrac{y_2 - y_1}{x_2 - x_1}$

$\qquad \sf \dashrightarrow \:m = \dfrac{4 - 0}{0 - 1}$

$\qquad \sf \dashrightarrow \:m = - 4$

Now, since we already know the gradient let's find of the equation of line by using its Slope and one of the points using point slope form of line :

$\qquad \sf \dashrightarrow \:y - 4 = m(x - 0)$

$\qquad \sf \dashrightarrow \:y = mx + 4$

Now, plug in the value of gradient ~

$\qquad \sf \dashrightarrow \:y = - 4x + 4$

here we can clearly observe that, the Area under the curve can easily be represented as :

$\qquad \sf \dashrightarrow \:y < - 4x + 4$

Since, all the values of y that lies in the shaded region is smaller than the actual value of y for the corresponding values of x in the equation of line q

Hello,
$f(1)=2\\
f(2)= \dfrac{2}{5} =2*5^{-1}\\
f(3)= \dfrac{2}{25} =2*5^{-2}\\
f(4)= \dfrac{2}{125} =2*5^{-3}\\\\

\boxed{f(x)= 2*5^{-x}} \\

thomas want to save money for a vacation. Thomas invest $1,300 in account that pays an interest rate of 6.25% how many years wil

Harrizon [31]

Answer:

44.2 years

Step-by-step explanation:

If we assume the interest is compounded annually and the investment is a one-time deposit into the account, its value each year is multiplied by 1+6.25% = 1.0625. After n years, the value in the account will be ...

19000 = 1300·1.0625^n

Dividing by 1300 and taking logs, we have ...

log(19000/1300) = n·log(1.0625)

log(190/13)/log(1.0625) = n ≈ 44.24 . . . . years

It will take about 44.2 years for the account to reach $19,000.
