Tina is saving to buy a notebook computer. She has two options. The first option is to put $400 away initially and save $10 every month. The second option is to put $300 away initially and save $30 every month. After how many months would Tina save the same amount using either option? How much would she save with either option?

Answers

Answer:

After 5 months, both options will have saved 450$

Step-by-step explanation:

The first option can be modeled with the expression

400 + 10x

The second option can be modeled with the expression

300 + 30x

The variable x represents the months so in order to find the month where Tina saves the same amount, we set the expressions equal to each other.

400 + 10x = 300 + 30x

solve for x

20x = 100

x = 5

After 5 months, Tina will save the same amount of money which is

400 + 10*5 = $450

. A right cylindrical drum is to hold 7.35 cubic feet of liquid. Find the dimensions (radius of the base and height) of the drum which would minimize the surface area. What is the minimum surface area

Answers

Answer:

[tex]r=1.05\ \text{ft}[/tex]

[tex]h=2.12\ \text{ft}[/tex]

[tex]20.91\ \text{ft}^3[/tex]

Step-by-step explanation:

r = Radius

h = Height

Volume of cylinder = [tex]7.35\ \text{ft}^3[/tex]

[tex]V=\pi r^2h\\\Rightarrow h=\dfrac{V}{\pi r^2}\\\Rightarrow h=\dfrac{7.35}{\pi r^2}[/tex]

Surface area is given by

[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi r^2+2\pi r\dfrac{7.35}{\pi r^2}\\\Rightarrow A=2\pi r^2+\dfrac{14.7}{r}[/tex]

Differentiating with respect to radius we get

[tex]\dfrac{dA}{dr}=4\pi r-\dfrac{14.7}{r^2}[/tex]

Equating with zero we get

[tex]0=4\pi r-\dfrac{14.7}{r^2}\\\Rightarrow 4\pi r=\dfrac{14.7}{r^2}\\\Rightarrow r^3=\dfrac{14.7}{4\pi}\\\Rightarrow r=(\dfrac{14.7}{4\pi})^{\dfrac{1}{3}}\\\Rightarrow r=1.05[/tex]

[tex]\dfrac{d^2A}{dr^2}=4\pi-2\times \dfrac{14.7}{r^3}\\\Rightarrow \dfrac{d^2A}{dr^2}=4\pi+2\times \dfrac{14.7}{1.05^3}\\\Rightarrow \dfrac{d^2A}{dr^2}=37.96>0[/tex]

So, the value of the function is minimum at [tex]r=1.05[/tex]

[tex]h=\dfrac{7.35}{\pi r^2}=\dfrac{7.35}{\pi 1.05^2}\\\Rightarrow h=2.12[/tex]

So, the radius and height which would minimize the surface area is 1.05 feet and 2.12 feet respectively.

Surface area

[tex]A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi \times 1.05^2+2\pi 1.05\times 2.12\\\Rightarrow A=20.91\ \text{ft}^3[/tex]

The minimum surface area is [tex]20.91\ \text{ft}^3[/tex].

Suppose you have 9 tubes of paint. How many distinct color groupings can you make with your paint?

Answers

9514 1404 393

Answer:

  511

Step-by-step explanation:

Each tube can be included in the mix, or not. There are 2^9 = 512 possible subsets of a set of 9 objects, including the complete set and the empty set. The empty set will not make a color, so there are ...

  2^9 - 1 = 511 distinct color groupings that can be made

__

The assumption in the above answer is that no tube color can be made by any combination of other tube colors.* We also assume that the choice of tubes is what makes a "color grouping", and that the colors within that grouping made by using different ratios of paint quantities are not counted separately.

A bean plant grows at a constant rate for a month. After 10 days, the plant is 35 centimeters tall. After 20 days, the plant is 55 centimeters tall. Which equation models the height of the plant, y, after x days?

Answers

Answer: Good afternoon fellow student, to answer your question

y - 35 = 2(x - 10)

Step-by-step explanation:

Let

y----->  the height of the plant

x ----> the number of days

Find the slope

we have the points

(10,35)

The slope is equal to

m= (55-35)/(20-10)

m= 2

Find the equation of the line into point slope form

y- y1 = m(x - x1)

we have

m= 2 and point (10,35)

y - 35 = 2(x - 10)

Explain how the vertical line test was robes that a relation is not a function.

Answers

The vertical line test is used to determine if a graph of a relationship is a function or not. if you can draw any vertical line that intersects more than one point on the relationship, then it is not a function. The vertical line test can be used to determine whether a graph represents a function. If we can draw any vertical line that intersects a graph more than once, then the graph does not define a function because a function has only one output value for each input value. Cutting or Hitting the Graph at Exactly One Point

If a vertical line intersects the graph in some places at more than one point, then the relation is NOT a function. Here are some examples of relations that are NOT functions because they fail the vertical line test.

If f is the function defined by f(x) = 3x^5 - 5x^4, what are all the x coordinates of points of inflection for the graph of f?

a. -1
b. 0
c. 1
d. 0 and 1
e. -1, 0, and 1

Answers

Answer:

D: 0 and 1

Step-by-step explanation:

Function is defined by;

f(x) = 3x^(5) - 5x⁴

Now, an inflection point will be a point on the graph where the inflection or concavity changes.

Thus, let's find the derivatives until we get there;

f'(x) = 15x⁴ - 20x³

f''(x) = 60x³ - 60x²

So factorizing gives;

f''(x) = 60x²(x - 1)

At f''(x) = 0, we have; x = 0 or x = 1

Thus, the x coordinates of points of inflection are 0 & 1

A student performed the following construction for the angle bisector of ZDAE. is the student's construction correct?
Yes. The student's construction is correct because circle A and circle D are the same size.
O No. The student's construction is not correct because circle D and circle E are not the same size.
Yes. The student's construction is correct because EH = DH
O No. The student's construction is not correct because AHDH.

Answers

The correct option is b). No. The student's construction is not correct because circle D and circle E are not the same size.

What is meant by angle bisector?

An angle bisector is a ray, segment, or line which divides a provided angle into two equal-sized angles. The term bisector or bisection refers to the process of dividing something into two equal parts.

In geometry, the angle bisector is the ray, line, or segment that divides a provided angle into two equal parts. An angle bisector, for example, will divide a 60-degree angle into two 30-degree angles. In other words, it separates an angle into two congruent smaller angles.

Now, as per the given question;

If line AH is the angle bisector of angle DAE, circle D as well as circle E should be the same size to ensure triangle ΔHDA ≅ Δ HEA, from which ∠ DAH= ∠EAH is deduced. Angle bisector properties

Thus, the student's construction again for angle bisector of DAE is incorrect because circle D or even circle E aren't the same size.

Find the diameter of this circle.

A. [tex]2\sqrt{10}[/tex]
B. [tex]4\sqrt{10}[/tex]
C. 8
D. [tex]2\sqrt{34}[/tex]

Answers

Answer:

A

Step-by-step explanation:

From looking at the graph, you can see that the center point of the circle is at (5, -3), so to figure out the diameter, you need to find the distance of that line ( y = - 3 ) that the circle is on. The diameter is about 6 point something which in the square root form can be represented by √36.

After knowing the diameter is about 6, choice C can be eliminated.

2√10 = √40

4√10 = √160

2√34 = √136

After expanding the square root, we can know that the closest option is A.

Check the picture below.

so we know the circle has that center and passes through (2 , -2), let's find its radius, keeping in mind that diameter = 2 * radius.

[tex]~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{2}~,~\stackrel{y_1}{-2})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{-3})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ \stackrel{radius}{r}=\sqrt{(~~5 - 2~~)^2 + (~~-3 - (-2)~~)^2} \implies r=\sqrt{(5 -2)^2 + (-3 +2)^2} \\\\\\ r=\sqrt{( 3 )^2 + ( -1 )^2} \implies r=\sqrt{ 9 + 1 } \implies r=\sqrt{ 10 }~\hfill \underset{diameter}{\stackrel{(2)(r)}{2\sqrt{10}}}[/tex]
