Given: B is the midpoint of AC
EB=BC

Prove: AB=BC

Answers

Answer:

Step-by-step explanation:Since B is the midpoint of AC, this means that AB and BC are equal in length, as the midpoint of a line segment divides it into two equal parts.

2. Let's assume that AB is not equal to BC. In this case, one of the line segments AB or BC would be longer than the other.

3. Since EB = BC, if AB is longer than BC, then EB would be shorter than AB. But since B is the midpoint of AC, EB and BC should be equal in length.

4. Similarly, if BC is longer than AB, then EB would be longer than BC. But again, EB and BC should be equal since B is the midpoint of AC.

5. Since assuming AB is not equal to BC leads to contradictions, our assumption is false. Therefore, AB must be equal to BC.

The Social Security (FICA) wage base ,y, (in thousands of dollars) from 1983 to 1988 is given by the equation y=1.9x+34.1, where x is the number of years since 1983. What was the FICA wage base in 1995? (A) $48,200 (B) $53,100 (C) $56,900 (D) $58,800

Answers

Answer:

C. $56,900

Step-by-step explanation:

Given the equation of the Social Security (FICA) wage base y, (in thousands of dollars) from 1983 to 1988 expressed as y=1.9x+34.1

for us to calculate his wage base in 1995, we need to calculate the total number of years between 1983 to 1995 i.e 12 years

Substitute x = 12 into the expression above as shown;

y=1.9x+34.1

y = 1.9(12)+ 34.1

y = 22.8 + 34.1

y = 56.9

Since y is in thousand of dollars then

y = 56.9 * 1000

y = 56900

y = $56,900

Hence FICA wage base in 1995 is $56,900

Differentiate. y=ln (17-x)

Answers

We have to use the chain rule's

$f(x)=ln(17-x)$

$f[g(x)]=ln[g(x)]$

therefore

$f(u)=ln(u)$

and

$u=g(x)=17-x$

them we have

$f'(x)=f'(u)*g'(x)$

$f'(u)=(1)/(u)$

$g'(x)=-1$

$f'(x)=f'(u)*g'(x)$

$f'(x)=(1)/(u)*(-1)$

$f'(x)=-(1)/(u)$

$\boxed{\boxed{\therefore~f'(x)=-(1)/(17-x)}}$

$y'=(17-x)'\cdot (1)/(ln(17-x)) =- (1)/(ln(17-x)) \n\n \ \ and\ \ \ D: \ 17-x > 0\ \ \ \Rightarrow\ \ \ x<17\ \ \ \Rightarrow\ \ \ D=(17;+\infty)$
