Q. Let us assume a triangle ABC which has only one acute angle (say ZA) Then we have

the following three cases:

(1) The other two angle (ZB and ZC) are right angles

Then ZA+ ZB+ ZC = LA + 90°+90° = ZA+ 180'>180" which is not possible,

(II) Then other two angles (ZB and 2C) are obtuse angles Then ZA+ ZB +ZC> 180° which is not possible

(iii) One angle (say ZB) is right and the other angle( 2C) is obtuse.

In physics, a force is any interaction that, when unopposed, will change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. WikipediaIn physics, a force is any interaction that, when unopposed, will change the motion of an object.

Answer 2

Account A: Decreasing at 8 % per year

Account B: Decreasing at 10.00 % per year

The amount f(x), in dollars, in account A after x years is represented by the function below:

f(x) = 10,125(1.83)x

Account B shows the greater percentage

change

Step-by-step explanation:

Part A: Percent change from exponential

formula

f(x) = 9628(0.92)*

The general formula for an exponential

function is

y = ab^x, where

b = the base of the exponential function.

if b < 1, we have an exponential decay

function.

f(x) decreases as x increases.

Account A is decreasing each year.

We can rewrite the formula for an

exponential decay function as:

y= a(1 – b)”, where

1- b = the decay factor

b = the percent change in decimal

form

If we compare the two formulas, we find

0.92 = 1- b

b = 1 - 0.92 = 0.08 = 8 %

The account is decreasing at an annual rate of 8%. The account is decreasing at an annual rate of 10.00%.

Account B recorded a greater percentage change in the amount of money over the previous year.
