Interest = (initial deposit)(interest rate)(time)
interest = (5750)(0.045)(3.5)
interest = $905.63

1.What values could replace the "?" in these equations to make them true?

Inga [223]

Answer:

Remember that logarithms are inverse of exponentials. That means the result of the logarithm is equal to the exponent of a power with the same base.

$log_{10} (10)=1$

Notice that the result is one beacuse $10^{1}=10$

$log_{10}(10000)=4$

Because $10^{4}=10000$

$log_{10}(?) =7 \implies 10^{7} =10000000$

So, $log_{10}(10000000)=7$

I would say to thim that $x$ and $y$ are variables of the logarithm, which be solved by imagine the logarithm as an exponential like

$log_{10} (x)=y \implies 10^{y}=x$

In other words, the $y$ is the exponent and the $x$ is the result of the exponential.

Dont understand it, so yeah need some help

Sonja [21]

Answer:

-4

Step-by-step explanation:

We have the coordinates (6, 3) and (8, 4), allowing us to calculate the slope (or gradient). To do this, you divide the change in y by the change in x, which is 1/2 which is a half.

The form of a linear equation is y = mx + c, where m is the gradient and c is the y-intercept.

We have the gradient, so we can put it in the equation:

y = x/2 + c

We can now substitute in a pair of our coordinates and rearrange to find the y-intercept.

3 = 6/2 + c

3 = 3 + c

c = 0

Therefore the equation for our line is y = x/2.

We can now put in the y coordinate we were given to work out the corresponding x coordinate:

-2 = x/2

x = -4

Therefore n is -4.

A bag contains white,blue and red balls ratio8:3:2 and there are 10 red balls,if 10 white balls and 10 blue balls are removed fr

dmitriy555 [2]

Answer:

New ratio ( white,blue and red) = 6:1:2

Step-by-step explanation:

Given:

Old ratio ( white,blue and red) = 8:3:2

Number of red balls = 10

Removed balls = 10 white , 10 blue

Find:

New ratio ( white,blue and red)

Computation:

Assume total number of balls = x

So,

Number of total balls = 2x / 13 = 10

Number of total balls = 65

Number of white balls = 40

Number of blue balls = 15

So,

Number of new white balls = 40 - 10 = 30

Number of new blue balls = 15 - 10 = 5

New ratio ( white,blue and red) = 30 : 5 : 10

New ratio ( white,blue and red) = 6:1:2
