Answer:

Step-by-step explanation:

a^2+2ab+b^2

Answer:

C

Step-by-step explanation:

The formula for effective annual interest rate is:

[tex]r=(1+\frac{i}{n})^{n}-1[/tex]

where

r is the effective annual interest rate

i is the stated interest rate (here, it is 1.55%, or 0.0155)

n is the number of compounding periods (here, compounded monthly, so it means 12 times a year, so n = 12)

plugging these info into the formula, we get:

[tex]r=(1+\frac{i}{n})^{n}-1\\r=(1+\frac{0.0155}{12})^{12}-1\\r=0.0156[/tex]

0.0156 * 100 = 1.56%

correct answer is C

Answer:

The answer is C

i got it right on Plato : ) Brainliest?

For this case we have that by definition:

1 pound is equivalent to 16 ounces.

We make a rule of three to determine the ounces of butter:

1lb ------------------------> 16onzas

[tex]\frac {1} {12}[/tex]----------> x

Where "x" represents the ounces of butter

[tex]x = \frac {\frac {1} {12} * 16} {1}\\x = \frac {16} {12}\\x = \frac {8} {6}\\x = \frac {4} {3}[/tex]

Thus, there are [tex]\frac {4} {3}[/tex]ounces of butter.

Now we must find the amount of eggs that remain:

[tex]92- (43+ \frac {1} {5}) =\\92 - (\frac {43 * 5 + 1} {5}) =\\92 - (\frac {215 + 1} {5}) =\\92 - (\frac {216} {5}) =\\92-43.2 =\\48.8[/tex]

Round down. There are 48 eggs left.

Answer:

There are [tex]\frac {4} {3}[/tex] ounces of butter.

C:  AB is the radius of both circles.

Answer:

C. line segment AB is the radius of both circles.

Step-by-step explanation:

If point A is the center of the first circle and point B is the center of the second circle (in the figure), therefore Line segment AB is the radius of both circles and we write.

Line segment AB = line segment AC (radius of first circle ) and

line segment  AB =  line segment BC (radius of second circle).

Hence line segment AB is the radius of both circle is the correct option for AB =AC.

Answer:

The last graph

Step-by-step explanation:

The problem presented here is similar to a compound interest problem since we have an initial value, a growth constant and the aspect of time.

We can consider the number of television sets currently produced by the company to be our Principal amount;

P = 2000

The rate of increase in production per month can be considered as our interest rate earned;

r = 25% = 0.25

The total number of television sets y will be our Accumulated amount;

A = y

The duration x becomes our time n.

The compound interest formula is given as;

[tex]A=P(1+r)^{n}[/tex]

We simply substitute the given information into the formula;

[tex]y=2000(1.25)^{x}[/tex]

This is an exponential growth function since the base of the exponent x is greater than 1.

A graph of the function will be an exponential curve passing through ( 0, 2000) since 2000 is our initial value

Gum’s Maximum height: 8ft

2nd part

How far does the gym travel in one revolution of the bicycle wheel?

2pi

Answer:

Minimum height of gum = 6 foot.

Maximum height of gum = 8 foot.

Step-by-step explanation:

A rider is riding a bicycle on a 6 foot wall, therefore the height of the lowest point of the rear wheel is 6 foot from the ground and highest point of the rear wheel is (6+2) foot = 8 foot ( because diameter of rear wheel =2 foot ).

If a piece of gum become stuck to the rear wheel, hence the minimum height of the gum is 6 foot from the ground and maximum height of the gum is 8 foot  from the ground.

Step-by-step

Answer:

A (-4, -4), B (-2, 6), C (-1, 1), D(-3, -5)

Step-by-step explanation:

Before the rotation:

A (-4, 4), B (6, 2), C (1, 1), D(-5, 3)

270° rotation clockwise is the same as 90° counterclockwise.  To do that transformation:

(x, y) → (-y, x)

Therefore, the coordinates of the rotated figure are:

A (-4, -4), B (-2, 6), C (-1, 1), D(-3, -5)

The coordinates of the image are:

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

This question is solved applying a 270° clockwise about the origin, which has the following rule:

[tex](x,y) = (-y,x)[/tex]

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

Coordinate A:

At the Figure, coordinate A is A(-4,4). Applying the rule:

[tex](-4,4) = (-4, -4)[/tex]

So the image of A is A'(-4,-4).

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

Coordinate B:

At the Figure, coordinate B is B(6,2). Applying the rule:

[tex](6,2) = (-2, 6)[/tex]

So the image of B is B'(-2,6).

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

Coordinate C:

At the Figure, coordinate C is C(1,1). Applying the rule:

[tex](1,1) = (-1, 1)[/tex]

So the image of C is C'(-1,1).

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

Coordinate D:

At the Figure, coordinate C is D(-5,3). Applying the rule:

[tex](-5,3) = (-3,-5)[/tex]

So the image of D is D'(-3,-5).

Choice B is correct

Step-by-step explanation:

The given radical division can be expressed in the following form;

[tex]\frac{\sqrt{16x^{3} } }{\sqrt{8x} }[/tex]

Using the properties of radical division, the expression can be expressed in the following form;

[tex]\sqrt{\frac{16x^{3} }{8x} }=\sqrt{2x^{2} }[/tex]

Simplifying further yields;

[tex]\sqrt{2x^{2} }=\sqrt{2}*\sqrt{x^{2} }=x\sqrt{2}[/tex]

Choice B is thus the correct alternative

For this case we must simplify the following expression:

[tex]\frac {\sqrt {16x ^ 3}} {\sqrt {8x}} =[/tex]

Join the terms in a single radical:

\[tex]\sqrt {\frac {16x ^ 3} {8x}} =\\\sqrt {\frac {8 * (2x ^ 3)} {8x}} =\\\sqrt {\frac {2x ^ 3} {8x}} =\\\sqrt {2x ^ 2} =\\\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

EXPLANATION

An algebraic expression contains letters and numbers that are connected with mathematical operators or symbols.

The sum of x and 6 as an algebraic up expression is:

x+6

This expression contains a variable , a mathematical symbol and a number.

For this case we have a system of two equations with two unknowns:

[tex]x = -3y-13\\2x + 2y = -6[/tex]

To solve we follow the steps below:

We substitute the first equation in the second:

[tex]2 (-3y-13) + 2y = -6[/tex]

We apply distributive property to the terms of parentheses:

[tex]-6y-26 + 2y = -6[/tex]

We add 26 to both sides of the equation:

[tex]-6y + 2y = -6 + 26\\-4y = 20\\y = \frac {20} {- 4}\\y = -5[/tex]

We find the value of x:

Answer:

The maximum value is 126 occurs at (9 , 9)

Step-by-step explanation:

* Lets remember that a function with 2 variables can written

 f(x , y) = ax + by + c

- We can find a maximum or minimum value that a function has for

 the points in the polygonal convex set

- Solve the inequalities to find the vertex of the polygon

- Use f(x , y) = ax + by + c to find the maximum value

∵ 8x + 2y = 36 ⇒ (1)

∵ -3x + 6y = 27 ⇒ (2)

- Multiply (1) by -3

∴ -24x - 6y = -108 ⇒ (3)

- Add (2) and (3)

∴ -27x = -81 ⇒ divide both sides by -27

∴ x = 3 ⇒ substitute this value in (1)

∴ 8(3) + 2y = 36

∴ 24 + 2y = 36 ⇒ subtract 24 from both sides

∴ 2y = 12 ⇒ ÷ 2

∴ y = 6

- One vertex is (3 , 6)

∵ 8x + 2y = 36 ⇒ (1)

∵ -7x + 5y = -18 ⇒ (2)

- Multiply (1) by 5 and (2) by -2

∴ 40x + 10y = 180 ⇒ (3)

∴ 14x - 10y = 36 ⇒ (4)

- Add (3) and (4)

∴ 54x = 216 ⇒ ÷ 54

∴ x = 4 ⇒ substitute this value in (1)

∴ 8(4) + 2y = 36

∴ 32 + 2y = 36 ⇒ subtract 32 from both sides

∴ 2y = 4 ⇒ ÷ 2

∴ y = 2

- Another vertex is (4 , 2)

∵ -3x + 6y = 27 ⇒ (1)

∵ -7x + 5y = -18 ⇒ (2)

- Multiply (1) by 7 and (2) by -3

∴ -21x + 42y = 189 ⇒ (3)

∴ 21x - 15y = 54 ⇒ (4)

- Add (3) and (4)

∴ 27y = 243 ⇒ ÷ 27

∴ y = 9 ⇒ substitute this value in (1)

∴ -3x + 6(9) = 27

∴ -3x + 54 = 27 ⇒ subtract 54 from both sides

∴ -3x = -27 ⇒ ÷ -3

∴ x = 9

- Another vertex is (9 , 9)

* Now lets substitute them in f(x , y) to find the maximum value

∵ f(x , y) = 9x + 5y

∴ f(3 , 6) = 9(3) + 5(6) = 27 + 30 = 57

∴ f(4 , 2) = 9(4) + 5(2) = 36 + 10 = 46

∴ f(1 , 5) = 9(9) + 5(9) = 81 + 45 = 126

- The maximum value is 126 occurs at (9 , 9)

The maximum value of the function for the polygonal convex set determined by a system of inequalities can be found using linear programming. The key steps are to plot the inequalities, find the vertices of the feasible region, and substitute these points into the function to find the maximum value.

This problem is related to linear programming, which is a method to achieve the best outcome in a mathematical model whose requirements are represented by linear relationships. To find the maximum value of the function for the polygonal convex set determined by the given system of inequalities, you essentially need to apply the rules of linear programming.

Firstly, plot the system of inequalities on a coordinate system to determine the feasible region, which is the polygonal convex set. Then, find each vertex of this polygonal convex set. These vertices are points where boundaries of the system of inequalities intersect. Once you have these vertices, substitute each of them into the function you are maximizing. The largest output will be the maximum value of the function within the given polygonal convex set.
