A TV has an original price of $599. Enter the new price after the given percent of change.
20% increase
The percent decrease is ? %
Answer:
The new price = $718. 8
Step-by-step explanation:
Original Price = $599
Given that the increase is 20%.
i.e.
Thus,
The amount of 20% Percentage increase = 20/100 × 599
= 0.2 × 599
= $119.8
Therefore,
New price = Original price + 20% increase amount
= 599 + 119.8
= $718. 8
Therefore, the new price = $718. 8

Answer:
D is the answer
Step-by-step explanation:
If f(x) = 3x – 7 and g(x) = x2 – 5x + 5, then f(x) = g(x) for
what values of x?
a. x = 3 and x = 4
b. X = 6 and x = 2
c. x = -6 and x = -2
d. x = -3 and x = -4
Answer:
b
Step-by-step explanation:
3x - 7 = x² - 5x + 5
x² - 5x + 5 - 3x + 7 = 0
x² - 8x + 12 = 0
(x-6)(x-2)=0
x = 6
x = 2
The Question is above.
Step-by-step explanation:
given
g(r)= -1 -7r
g ( 6) = - 1 - 7 * 6
= - 1 - 42
= - 43

I need to find the equation of the graphed line.
Answer:
y=-x-7
Step-by-step explanation:
So the line goes down one unit for every unit it goes to the left.
Slope is rise over run which would be -1/1 (simplify to -1)
The line crosses the y axis at -7
So to put it in slope-intercept form (y=mx+b) it would be y=-1x-7
You don't have to include the one in -1x because its the same as saying -x
Answer: 20-w33
Step-by-step explanation:
So easy yaar! SO. EASY!

Determine which is the better buy. (picture below)
Answer:
Cheese B
Step-by-step explanation:
Find the cost of 1 slice for Cheese A:
Set up a proportion: [tex]\frac{3.59}{10} = \frac{x}{1}[/tex] Cross multiply, then divide: 3.59 × 1 = 3.59, 3.59 ÷ 10 = 0.359So, the cost of 1 slice of Cheese A is $0.359Find the cost of 1 slice for Cheese B:
Set up a proportion: [tex]\frac{5.12}{16} = \frac{x}{1}[/tex] Cross multiply then divide: 5.12 × 1 = 5.12, 5.12 ÷ 16 = 0.32So, the cost of 1 slice of Cheese B is $0.32Make a conclusion:
Because $0.32 is less than $0.359, Cheese B is the better buy.

Cost of four DVD= 36.7, but due to 25% discount it cost 27.57. Then add 7.75 taxes and he payed 29.71. Answer is 29.71
Step-by-step explanation:
Answer:
$27.71
Step-by-step explanation:
Price of 1 DVD: $9.19
Price of 4 DVDs: 4 * $9.19 = $36.76
Discount: 25%
Now we find 25% of $36.76.
25% of $36.76 =
= 0.25 * $36.76
= $9.19
The 25% discount amounts to $9.19. We now subtract $9.19 from $36.76 to find the discounted price.
$36.76 - $9.19 = $27.57
Now we need to apply the 7.75% tax to $27.57.
7.75% of $27.57 =
= 0.0775 * $27.57
= $2.14
The sales tax is $2.14.
Now we add the sales tax amount to the total discounted price.
$27.57 + $2.14 = $29.71
Answer: $27.71

Erik works 55 hours a week making $12.50 hour? His employer pays time and a half for hours over 40. Find his gross pay.
Answer:
781.25
Step-by-step explanation:
Regular pay = 40*12.50 = 500.00
Overtime = 15*12.5*1.5 = 281.25
Gross pay = 500.00 + 281.25 = 781.25

Hi everyone! I have a question!
Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of pi (no approximations.) THANKS!!!!!!
Answer:
7π
Step-by-step explanation:
SO first find the area of the whole circle
which has a radius of 3
a=πr^2
So 3^2=9
9π
Now the two circles which are the same in area due to having the same radius
so if you plug in the 1 for radius the answer would just be π or 1π
now multiply that by 2 becuase there are 2 identical circles
π*2=2π
Now subtract
9π-2π=7π
Answer:
Step-by-step explanation:
area of unshaded circle:
A=π*r^2=π*1=π
we have 2 circles so the area of both circles are 2π
area of the large circle is A(l)=Π*3^2=Π*9=9Π
area of the shaded region: A(s)=9Π-2Π=7Π
Question and answer choices are attached. Please pick the right answer and explain/show work if possible. Thanks!
Answer:
Choice c. [tex]\sqrt{12}[/tex]
Step-by-step explanation:
Vectors
Suppose we have a vector v defined as
[tex]\vec v=a\mathvf{i}+b\mathvf{j}[/tex]
The magnitude of the vector is:
[tex]\mid\mid\vec v\mid\mid=\sqrt{a^2+b^2}[/tex]
On the other hand, the dot product of the vector by itself is:
[tex]\vec v\cdot\vec v=a*a+b*b=a^2+b^2[/tex]
Note the relation between these two operations is:
[tex]\mid\mid\vec v\mid\mid=\sqrt{\vec v\cdot\vec v}[/tex]
Since we are given:
[tex]\vec v\cdot\vec v=12[/tex], then:
[tex]\mid\mid\vec v\mid\mid=\sqrt{12}[/tex]
Choice c) [tex]\sqrt{12}[/tex]
What type of exponential function is f(x)=0.6(2.4)^x?
What is the function's percent rate of change?
Select from the drop-down menus to correctly complete each statement.
The function is an exponential CHOOSE function.
The percent rate of change of the function is CHOOSE%.
Answer:
growth
140%
Step-by-step explanation:
The function f(x) is an exponential growth function as f(x) increases when x increases.
The percent rate of change of the function f(x) is 201.6%.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = 0.6 [tex](2.4)^x[/tex]
For x = 1,
f(1) = 0.6 x 2.4 = 1.44
For x = 2,
f(2) = 0.6 x 2.4² = 0.6 x 5.76 = 3.456
For x = 3,
f(3) = 0.6 x 2.4³ = 0.6 x 18.824 = 8.2944
We see that,
As the value of x increases, the value of f(x) increases.
f(x) is an exponential growth function.
Now,
The percentage rate of change of function f(x).
= (f(2) - f(1)) / (2 - 1) x 100
= (3.456 - 1.44) x 100
= 2.016 x 100
= 201.6 %
Thus,
f(x) is an exponential growth function.
f(x) percent rate of change is 201.6%
