At an electronics store, a $165 television is marked up 110%. Trevor purchases the TV and must pay 6.5% sales tax. What is the total cost of this television at the store?
A. $193.30
B. $299.48
C. $369.02
D. $571.73

Answers

Answer 1
Answer:

The total cost of this television at the store will be $ 193.30. Then the correct option is A.

What is the percentage?

The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol 'percent' is used to symbolize it.

At an electronics store, a $165 television is marked up 110%.

Trevor purchases the TV and must pay 6.5% sales tax.

Then the total cost of this television at the store will be

Total cost of TV = $ 165 x 1.10 x 1.065

Total cost of TV = $ 193.30

Thus, the correct option is A.

Negative times a Negative = Positive
Positive times a Positive = Positive
Negative times a Positive = Negative
Positive times a Negative = Negative

Option A:

Negative * Positive * Negative * Positive

Negative * Negative * Positive

Positive * Positive

Positive

Option B:

Anything times 0 is 0, this is incorrect.

Option C:

Negative * Negative * Negative * Negative

Positive * Negative * Negative

Negative * Negative

Positive

Option D:

Negative * Positive * Negative * Negative

Negative * Negative * Negative

Positive * Negative

Negative

Therefore your answer is D.

What is the average rate of change of the function f(x)=2(3)x from x = 2 to x = 4?Enter your answer in the box.

Answers

The average rate of change of function is 72.

SOLUTION:

Given that, we have to find the average rate of change of the function f(x)=2(3)x from x = 2 to x = 4  

Use the slope formula to find the average rate of change:  

\begin{array}{l}{m=(y 2-y 1)/(x 2-x 1)} \n\n {m=(f(4)-f(2))/(4-2)} \n\n {m=(f(4)-f(2))/(2)}\end{array}

To simplify this, we need to find values of f ( 4 ) and f ( 2 ) :  

\begin{array}{l}{f(4)=2 x(3)^(4)=2(81)=162} \n\n {f(2)=2(3)^(2)=2(9)=18} \n\n {m=(162-18)/(2)} \n\n {m=(144)/(2)} \n\n {m=72}\end{array}

What is the equation parallel to y= -1/5x + 3 and goes through the point (7,4)? Please show steps.

Answers

Answer:

Step-by-step explanation:

If it's parallel, that means it has the same slope: -1/5.

Use point-slope form to write the equation:

y - 4 = -1/5 (x - 7)

If you wish to write in point-intercept form:

y - 4 = -1/5 x + 7/5

y = -1/5 x + 27/5

If two lines are parallel, it means that they will have the same gradient:

And remember, the equation of a line is y = mx +c

-----------------------------------

So we know that the equation of the parallel line is:

y = - (1)/(5)x + c        through point (7, 4)

All we need to do now is to work out what c is

Note: at point (7,4)  x = 7 , and y = 4.

So to work out c, we substitute in the values of x and y, and solve:

y = - (1)/(5)x + c

4 = - (1)/(5) * 7 + c

4 = -1.4 + c

5.4 = c

----------------------------------

Finally, we just put the value of c back into the original equation

y = - (1)/(5)x + 5.4

------------------------------------------

Answer:

The equation of the a line parallel to y = - (1)/(5)x + 3    through point (7,4)

is: y = - (1)/(5)x + 5.4
