PLEASE HELP ME IM SO CONFUSED The volume of a cube is x³ cubic units. The surface area of the cube is x³ square units. What is the value of x?
Answer: The value of x is 6.
Step-by-step explanation:
TO find the volume of a cube you cube any side length. so if the side length is 6.
6^3 = 216
To find the surface area of a cube you will square one of the side lengths and multiply it by 6.
so the side length is 6 and 6 squared is 36
36*6 = 216

Answer:
(4, 4 )
Step-by-step explanation:
Given the 2 equations
y = x² - 6x + 12 → (1)
y = 2x - 4 → (2)
Substitute y = x² - 6x + 12 into (2)
x² - 6x + 12 = 2x - 4 ( subtract 2x - 4 from both sides )
x² - 8x + 16 = 0 ← in standard form
(x - 4)² = 0 ← in factored form
x - 4 = 0 ⇒ x = 4
Substitute x = 4 into (2) for corresponding value of y
y = 2(4) - 4 = 8 - 4 = 4
Solution is (4, 4 )

Gabriel notes on a timeline important family events. It uses positive or negative integers. To write a date before his birth, he uses negative numbers and for a date after his birth, positive numbers. For example, Gabriel's mother received a medal in the year -20 and Gabriel's sister was born in the year + 5. What does the year 0 represent? Answer:
A) The year when Gabriel's sister was born
B) The year when Gabriel was born
C) The year when Gabriel's mother received a medal
Solution
It was stated in the question that Gabriel recorded tge events in their lives relative to when he came into the picture. With noticeable examples given to illustrate that the negative numbers indicate times before Gabriel's birth and positive numbers indicate years after Gabriel's birth.
Hence, it is straighforward to see that the year 0 in relative terms to Gabriel's birth will represent the year in which Gabriel was born.

Which description matches the transformations y = cosx undergoes to
produce y = -3cos(x)+1?
A. Horizontal shift left 3 units, then vertical shift up by 1 unit
B. Horizontal compression by factor 3, vertical shift by 1 unit up, then a reflection across the x-axis
C. Vertical stretch by factor 3, reflection across the x-axis, then a
vertical shift up 1 unit
D. Reflection across the y-axis, vertical shift up by 1 unit, horizontal shift right by 3 units
Answer:
C.
Step-by-step explanation:
The parent function is y = cos(x).
When we have y = cos(x) + 1, this tells us that the graph has been shifted up by 1.
When we have y = -cos(x), this tells us that the graph has been reflected across the x-axis.
When we have y = 3cos(x), this tells us that the graph has been vertically stretched by a factor of 3.
All together, the answer is C.
Notes:
y = 3cos(x) would be a vertical stretch, while y = cos(3x) would be a horizontal compression.
y = -cos(x) is a reflection across the x-axis, while y = cos(-x) would be a reflection across the y-axis.
Which of the following is the graph of a linear function?
Answer:
The first one.
Step-by-step explanation:
A linear function is a straight line, regardless of direction.
The first graph is of a linear function.
The phrase linear function denotes to function which is linear, specifically of this form:
[tex]f(x) = mx + c[/tex]
This is also written as:
[tex]y = mx + c[/tex]
It is written so that we can take the outputs of the function f(x) in a separate variable for further mathematical treatments with ease.
Now when that second equation is plotted on XY plane, you get a straight line graph since this is the equation form of any straight line, in geometry.
All the straight lines are covered under y = mx + c linear function form.
Since the first graph contains a plot of straight line, thus the first graph is of linear function.
The second graph is of downwardly opened vertical parabola which is of degree 2, thus not linear.
Thus first graph is the graph of a linear function.

The radius of a circle is given as 10cm subject to an error of 0.2cm. the error in the area of the circle is?
Answer:
12.56 [tex]cm^2[/tex] is the error in area of circle.
Step-by-step explanation:
Given that:
Radius of the circle, r = 10 cm
Error in measurement of radius, [tex]\triangle r[/tex] = 0.2 cm
To find:
The error in area of circle = ?
Solution:
First of all, let us have a look at the percentage error in measurement of radius:
[tex]\dfrac{\triangle r}{r}\times 100 = \dfrac{0.2}{10}\times 100 = 2\%[/tex]
Now, we know that Area of a circle is given as:
[tex]A = \pi r^2[/tex]
[tex]\Rightarrow \dfrac{\triangle A}{A} \times 100 = 2 \times \dfrac{\triangle r}{r} \times 100\\\Rightarrow \dfrac{\triangle A}{A} = 4\%[/tex]
Area according to r = 10
[tex]A = 3.14\times 10^2 = 314 cm^2[/tex]
Now, error in area = 4% of 314 [tex]cm^2[/tex]
[tex]\Rightarrow \dfrac{4}{100} \times 314 = 12.56 cm^2[/tex]
So, the answer is:
12.56 [tex]cm^2[/tex] is the error in area of circle.

Matt bought some boards to build a wooden deck. Some of the boards were 4 ft long and some of the boards were 5 ft long. He bought 35 ft of boards altogether. How many boards altogether did Matt buy?
Answer:
8 boards.
Step-by-step explanation:
Since he bought a few of each length. The only combination that works is when he bought 5 of the 4 ft long board so 4×5=20. Than he bought 3 of the 5ft boards 3×5=15. 20+15=35 ft worth of boards.
Matt brought total 8 boards out of which the 5 boards are of 4ft and 3 boards are of 5ft.
We have a guy named Matt who bought some boards to build a wooden deck. Some of the boards were 4 ft long and some of the boards were 5 ft long. He bought 35 ft of boards altogether.
We have to find out how many boards he bought all together.
What do you mean by the solution of a equation ?The solution of an equation is the value at which the left hand side and right hand side of the equation equals to each other.
In the question, it is given that there are 4ft long and 5ft long boards and matt brought 35 ft of board all together.
Let us assume that the number of 4 ft boards he bought are = x and the number of 5ft boards be y, then according to question -
4x + 5y = 35
[tex]y = \frac{-4x + 35}{5} \\y=\frac{-4x}{5} + 7[/tex]
Now, all the points that lie on this line are the possible answers but the number of boards cannot be in decimal. Hence, the solution x = 5 and y=3, which will give us 4 x 5 + 5 x 3 which is equal to 35.
Hence, Matt brought 5 boards of 4ft and 3 boards of 5ft.

Sean is trying to decide between four Roth IRAs. The month after the required initial contribution (RIC), he wants to start contributing the minimum subsequent investment (MSI) each month. Compare the cost of the minimum initial investment and Sean's monthly contribution for each IRA over the next 10 years. Which Roth IRA would Sean put the most money in over those 10 years?
Answer:
Option C.
Step-by-step explanation:
So, in the question above we are given that the value or parameters for the required initial contribution (RIC) and
the minimum subsequent investment (MSI) for each options and we are going to calculate the amount that will be gotten after investing in each options and the one that gives the highest values will be the correct option, which in this case is OPTION C.
So, we will be starting from the OPTION C, in white have that the
required initial contribution (RIC) = $5,000 and the minimum subsequent investment (MSI) = $100 for option C.
One year = 12 months
10 years = x months.
x = 10 × 12 = 120 months in ten years.
Thus, the formula for the Calculation is given below;
= 120 months × minimum subsequent investment (MSI) + required initial contribution (RIC).
= (120 months × $100) + $5,000 = $17,000.
If we Calculate for the other options with this format, we will have values for option A = $13, 000 and option B= $2,900 and the value for the investment in option D = $12,050.
$17,000 is the highest which is for option option C. Therefore, Sean should put his money in option c for better investment.
