Cynthia invests some money in a bank which pays

1 answer:

8 0

Answer = £6911

Compound interest of 5% means multiplying by 1.05 each year.

Let’s call the missing value x

To find x, we need to do:

(X) * 1.05 * 1.05 * 1.05 = 8000

So, to find x, divide 8000 by 1.05^3

Which is 2logx-6log(x-9) written as a single logarithm

Elena-2011 [213]

Answer: option c.

Step-by-step explanation:

To solve the given exercise and write the expression as a single logarithm, you must keep on mind the following properties:

$m*log(a)=log(a)^m$

$log(a)-log(b)=log(\frac{a}{b})$

Therefore, by applying the properties shown above, you can rewrite the expression given, as following:

$2logx-6log(x-9)=logx^2-log(x-9)^6=log(\frac{x^2}{(x-9)^6})$

Then as you can see, the answer is the option c.

Answer:

Is the question to develop the equation for the straight line shown?

If so, y = (3/4)x + b

Step-by-step explanation:

Look for an equation with the form y = mx + b, where m is the slope and b is the y-intercept (the value of y when x = 0).

Calculate Slope using the Rise/Run.

Pick any two points. I chose (-4,0) and (4,6).

Going from left to right:

Rise = (6 - 0) = 6

Run = (4 - (-4)) = 8

Slope is Rise/Run, 6/8 or 3/4

So we have: y = (3/4)x + b

We can see that the y-intercept, b, is 3 (the value of y when x = 0).

The full equation becomes : y = (3/4)x + 3

If a baseball player hits a baseball from 4 feet off the ground with an initial velocity of 64 feet per second, how long will it

AleksAgata [21]

Right now that equation is a function of time, h(t), height with respect to time. If the baseball is on the ground, it has no height. In other words, its height = 0. So if we set the equation equal to 0 and solve for t, time, that will tell us the time that the ball had a height of 0. If you plug those numbers into the quadratic formula, which is the best and most efficient way to factor a quadratic, you will get that the times are -.0615528128 and 4.061552813 seconds. The 2 things in math that will never EVER be negative are time and distance/length. So we know that the ball will not hit the ground at -.062 seconds. Therefore, it hits the ground 4.06 seconds after it was hit.
