The answer is C.

You need you use Pythagoras theorem 2 times to have 2 equations with the same sides i.e. for example a2 + b2 = 81 and a2 - b2 = 9.

You can do it as you have different triangles but with the same sides.

Explain why the initial value of any function of the form<br> f(x) = a(bx) is equal to a.
Serggg [28]

Answer:

Step-by-step explanation:

f(x) = a(b^x), the initial value is always a, because a is independent of x , so when x changes only b^x changes.ex if  a = 2, b = 3, and x = 0: f(0) = 2 (3^0) = 2  If x = 1, then f(1) = 2 (3^1) = 2 (3). If x = 2, then f(2) = 2 (3^2) = 2 (9), as you can see a still the same.

What is the value of 6 in 4.769
mixer [17]
<span>The <u>correct answer</u> is:

6/100.

Explanation<span>:

We look at place value to answer this. The digit in front of the decimal is the ones; directly after the decimal we have the tenths; behind this we have the hundredths; and behind this we have the thousandths.

6 is two places behind the decimal; this is the hundredths place. This means it is six hundredths, or 6/100.</span></span>
