Answer:
0 and 8/3
Step-by-step explanation:
y is continuous on [0,4]
It also also differentiable on (0,4)
Plugging in 0 and 4, we get -3 both times so y(0) = y(4).
Therefore there is at least one value c between 0 and 4 inclusive where y'(c) = 0
y' = -3x^2 + 8x
Set that to 0:
-3x^2 + 8x = 0
x(-3x+8) = 0
x = 0 or 8/3
And both values work.

A store is having a sale. The price of a jacket is set to decrease by $1.50 during each hour of the sale. How long will it take for the price of the jacket to decrease by $18.00?
Answer: It will take 12 hours for the price of the jacket to decrease by $18
Step-by-step explanation: All you got to do for this problem is 18 divided by 1.50 to get $12.
The cost of manufactured goods is rising at the rate of inflation, or at about 2.3% 2.3 % . Suppose an item costs $12 $ 12 today. How much will it cost five years from now due to inflation? Round the answer to the hundredth.
Answer: $13.44
Step-by-step explanation:
Inflation is causing the manufactured goods to rise at 2.3% per year. The price in 5 years can be calculated using compound interest formula:
= 12 * ( 1 + 2.3%)⁵
= 13.444956907696116
= $13.44
Identify the coefficient of x.
Equation
Answer:
A coefficient is a number in front of a variable. For example, in the expression x 2-10x+25, the coefficient of the x 2 is 1 and the coefficient of the x is -10. The third term, 25, is called a constant.

Michael is leaving a 15% tip for his waitress. What percent of the
original price will he pay? Write your answer as a percent, decimal,
and fraction.
Answer:
As a percent: 115%
As a decimal: 1.15
As a fraction: [tex]\frac{23}{20}[/tex]
Step-by-step explanation:
Percentages
Suppose Michael spends some amount of money on food, and that money is set at 100%. He leaves a 15% tip for the waitress.
Thus, he is really paying 100%+15% = 115% of the original price.
To express a percentage as a decimal, we just divide by 100:
115% = 115/100 = 1.15
The same division should be simplified instead of operated to express the percentage as a fraction:
115% = [tex]\frac{115}{100}[/tex]
Simplifying by 5:
115% = [tex]\frac{23}{20}[/tex]
Summarizing:
As a percent: 115%
As a decimal: 1.15
As a fraction: [tex]\frac{23}{20}[/tex]

Select the graph for the solution of the open sentence. Click until the correct graph appears.
IX - 1l <4
Answer:
Here we can not see the options, so i will find the graph by the equation alone.
We start with:
Ix - 1I < 4
We could rewrite this as:
-4 < (x - 1) < 4
Now we can add 1 in the 3 parts, to get:
-4 + 1 < x - 1 + 1 < 4 + 1
-3 < x < 5
This means that the graph will be such that:
x > -3 (this is a dashed line at x = 3, and we shade the part in the right of that line)
and:
x < 5 (this is a dashed line at x = 5, and we shade the part in the left of that line)
The graph would look something like the one below
(If the graphs are only in one axis, you should see a white dot at x = -3, than a colour line that goes to the right until the point x = 5, where we have another white dot)
Please help out, what is the slope here? This question is worth 20 points
Answer:
the slope is 1
you find two points that are directly on an intersection of the grid. and then count rise/run
rise is going up and down and run is left and right
start at the point you found furthest to the left and count to the next point that's to the right.
if you have to go down to find it or left to find it, the slope is negative
in this case. theres a point at (-1,0) and (0,1)
you have to count up one and right one, making the slope 1/1 or simplified to 1

The vertices of a triangle are P[4.1). Q(2.-8), and R(-8.1). What are the vertices of the image reflected across the y-axis?
O A P14.-1), Q12,8), and RX-8.-1)
B. PY-4. 1). Q1-2.-8), and R(8.1)
OC. P(-4,-1). QT-2,8), and R18.-1)
OD. P14.1). Q12.-8), and R1-8.1)
Given:
The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1).
To find:
The vertices of the image reflected across the y-axis.
Solution:
The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1). It is reflected across the y-axis.
If a figure is reflected across the y-axis, then
[tex](x,y)\to (-x,y)[/tex]
Using this rule, we get
[tex]P(4,1)\to P_1(-4,1)[/tex]
[tex]Q(2,-8)\to Q_1(-2,-8)[/tex]
[tex]R(-8,1)\to R_1(8,1)[/tex]
So, the vertices of the image are [tex]P_1(-4,1), Q_1(-2,-8), R_1(8,1)[/tex].
Therefore, the correct option is B.
Note: Options are not in proper form.

What is the slope of the line through the points (-4, 2) and (-16, -6)?
2/3
−5/2
2/5
3/2
Answer:
The slope is equal to [tex]\frac{2}{3}[/tex] . So the right answer is A.
Step-by-step explanation:
We know that if we are given to points of a function we can find out its slope by using the following formula....
[tex]m = \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
Where m is the slope, [tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the coordinates of the first point, [tex]x_{2}[/tex] and [tex]y_{2}[/tex] are coordinates of the second point.
Let (-4, 2) be [tex](x_{1} , y_{1})[/tex]
Let (-16, - 6) be [tex](x_{2}, y_{2} )[/tex]
then......
The slope of the line will be [tex]\frac{2}{3}[/tex] i.e. option A is the correct answer.
What is slope?Slope is or gradient of a line is a number that describes both the direction and the steepness of the line.
Slope [tex](m) =\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
We have,
Points (-4, 2) and (-16, -6)
i.e.
x₁ = -4, x₂ = -16,
And,
y₁ = 2, y₂ = -6
Now,
Using the above mentioned formula,
Slope [tex](m) =\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
i.e.
Slope [tex](m) =\frac{-6-2}{-16-(-4)}[/tex]
On solving we get,
Slope [tex](m) =\frac{-8}{-12}=\frac{2}{3}[/tex]
So, the slope pf the given points is [tex]\frac{2}{3}[/tex] .
Hence, we can say that the slope of the line will be [tex]\frac{2}{3}[/tex] i.e. option A is the correct answer.

Find the length of side x in the simplest radical form with a rational denominator
Answer:
The value of x = 1
Step-by-step explanation:
Given
hypotenuse = √2 angle Ф = 45°To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 45°
adjacent of 45° = x
hypotenuse = √2
so substituting Ф = 45° adjacent = x and hypotenuse = √2 in the equation
cos Ф = adjacent / hypotenuse
[tex]\cos \left(45^{\circ \:}\right)=\frac{x}{\sqrt{2}}[/tex]
switch sides
[tex]\frac{x}{\sqrt{2}}=\cos \left(45^{\circ \:}\right)[/tex]
Multiply both sides by 2
[tex]\frac{2x}{\sqrt{2}}=2\cos \left(45^{\circ \:}\right)[/tex]
[tex]\sqrt{2}x=\sqrt{2}[/tex] ∵ [tex]\cos \left(45^{\circ \:}\right)=\frac{\sqrt{2}}{2}[/tex]
Divide both sides by √2
[tex]\frac{\sqrt{2}x}{\sqrt{2}}=\frac{\sqrt{2}}{\sqrt{2}}[/tex]
[tex]x=1[/tex]
Therefore, the value of x = 1
