A spinner has 5 sector's of equal size. The sectors are labeled 1,2,3,4, and 5. the spinner is spun twice.x is the number of times 3 is spun

Answer:

x = 10

Step-by-step explanation:

Please, use " ^ " to denote exponentiation:    g(x) = 4(x - 2)^2 - 4

The vertex is located at (2, -4) which numbers come directly from the '2' in (x - 2) and the "-4" at the end of the equation.

Where is the function f(x) that you mentioned?

The axis of symmetry here is the vertical line that passes through the vertex.  Its equation is x = 10.

The axis of symmetry for the function g(x) is x = 2, determined by the standard form of a quadratic equation, which tells us the axis of symmetry is at x = h, where g(x) is in the form a(x - h)^2 + k.

The question asks for the axis of symmetry for function g(x) which is given as g(x) = 4(x - 2)2 - 4. The axis of symmetry for a parabolic function in the form f(x) = a(x - h)2 + k is given by x = h. Thus, in the function g(x), the axis of symmetry is x = 2. If f(x) was provided in a similar quadratic form, its axis of symmetry would similarly be derived from its formula. However, since f(x) was not given in the question, we can't determine its axis of symmetry.

Answer:

(x + 8)(x - 8)

Step-by-step explanation:

Difference of squares

a^2 - b^2 = (a + b)(a - b)

In this case

x^2 - 64

= x^2 - 8^2

= (x + 8)(x - 8)

The equation x² - 64 is a difference of two squares and can be factored using the formula for the difference of squares, which leads to (x - 8)(x + 8).

The equation given is x² - 64, which is a difference of two squares. In mathematics, the difference of two squares is any expression that can be rewritten as the square of a number or expression, subtracted from the square of another number or expression. To factor this expression, we can use the formula a² - b² = (a - b)(a + b).

So, we have

x² - 64

= (x)² - (8)². Applying the formula, this factors to (x - 8)(x + 8).

The  expression for g(x) is g(x) = x^3, a cubic function that passes through the origin and is slightly narrower than the graph of f(x) = x^2.

 Certainly! Let's walk through the step-by-step calculation to determine the expression for g(x) based on the given information.

Given Information:

f(x) = x^2 (quadratic function)

Coordinate marked for g(x) is (2, 8)

g(x) is a parabola slightly narrower than f(x)

The curve g(x) passes through the origin

Expression for g(x):

Since g(x) is a parabola, we consider it as g(x) = ax^2 initially.

The coordinate (2, 8) helps determine the value of a.

g(2) = a(2)^2 = 4a = 8

Solving for a, we get a = 2.

So, g(x) = 2x^2 is the initial expression.

Adjusting for Narrowness:

If g(x) is slightly narrower than f(x), we need to make it narrower than 2x^2.

To achieve this, we can use g(x) = x^3.

Verification:

Check the coordinate (2, 8) in g(x) = x^3:

g(2) = 2^3 = 8

The coordinate (2, 8) satisfies the expression.

Answer:

True

Step-by-step explanation:

The region defined by the following inequality

[tex]4x+7y<5[/tex]

is delimited by the line: [tex]4x+7y=5[/tex]

Therefore the points that are on the line that delimits the region are those where  [tex]4x+7y=5[/tex]

Since the symbol "<" represents only the values that are smaller and excludes those that are greater or equal, then the points where  [tex]4x+7y=5[/tex] are not included in the region. This is represented by drawing a dotted line

The statement is true; the border line of the inequality 4x+7y<5 is drawn as a dotted line because it does not include the boundary points as part of the solution set.

The statement that the border line of the linear inequality 4x+7y<5 is dotted is true. When graphing a linear inequality, the border line is typically solid if the inequality includes the equality (≤ or ≥), which indicates that the points on the line are included in the solution set. However, when the inequality does not include equality ( < or > without the line underneath), as in 4x+7y<5, the border line is drawn as a dotted line, signifying that points on the line are not part of the solution set. Therefore, the given statement is correct and the border line should indeed be dotted.

Answer:

Step-by-step explanation:

We require to find RT

Since ΔRST is right use the sine ratio to find RT

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2\sqrt{3} }{RT}[/tex]

Multiply both sides by RT

RT × sin60° = 2[tex]\sqrt{3}[/tex] ( divide both sides by sin60° )

RT = [tex]\frac{2\sqrt{3} }{sin60}[/tex] = 4

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

Since ΔRTQ is right use the tangent ratio to find x

tan45° = [tex]\frac{RQ}{RT}[/tex] = [tex]\frac{x}{4}[/tex]

Multiply both sides by 4

4 × tan45° = x, hence

x = 4 × 1 = 4

That is x = 4

Answer:

Surface Area = 283

Step-by-step explanation:

Radius = 3

Height = 12

Formula for suface area is SA= 2πrh+2πr^2

let "r" be for radius

let "h" be for height

SA=2*π*3*12+2*π*3^2

SA=282.74

round to the nearest ones spot and that will make the surface area = 283

The surface area of a right cylinder with a radius of 3 and a height of 12 is calculated using the formula S = 2πr(h + r), resulting in S = 90π or approximately 282.6 square units.

The question is asking to calculate the surface area of a right cylinder with a known radius and height. The formula to find the surface area of a cylinder is S = 2πr(h + r), where r is the radius, and h is the height.

To calculate the surface area of the given cylinder with a radius of 3 and a height of 12, we plug in these values into the formula:

S = 2 × π × 3 × (12 + 3)

This simplifies to S = 2 × π × 3 × 15, which further simplifies to S = 2 × π × 45, and hence S = 90π. By multiplying this by the approximate value of π (3.14), we get S = 282.6 square units as the surface area of the cylinder.

The cross-sectional area (base area) of the cylinder is πr², which is the area of a circle with the same radius as the cylinder. The side surface area, which is the area of the rectangle that would be formed if you 'unrolled' the outer surface of the cylinder, is 2πrh. Adding two times the base area and the side surface area gives you the total surface area of the cylinder.

#SPJ2

Answer:

1 1/2 cups.

Step-by-step explanation:

If the quantity of chocolate chips is x cups then:

x * 2 1/3 =  3 1/2

x * 7/3 = 7/2

x = 7/2 / 7/3

x = 7/2 * 3/7

x = 3/2 = 1 1/2 cups.

The quantity of chocolate chips needed for the brownie recipe when using three and one half cups of sugar, divide the amount of sugar by the sugar-to-chocolate chips ratio of 2 1/3. The answer is one and one half cups of chocolate chips.

Related to ratios and proportions in a brownie recipe. If a recipe calls for two and one third times as much sugar as chocolate chips, and if three and one half cups of sugar is used, you can calculate the amount of chocolate chips required as follows:

First, it's important to understand the ratio given: 2 1/3 cups of sugar for every 1 cup of chocolate chips.

Next, since we know that 3 1/2 cups of sugar are used, you need to divide the amount of sugar by the ratio to find the amount of chocolate chips needed, which is, 3 1/2 divided by 2 1/3.

To perform the division, you first convert the mixed numbers into improper fractions. 3 1/2 becomes 7/2, and 2 1/3 becomes 7/3.

Now, divide 7/2 (the amount of sugar) by 7/3 (the sugar-to-chips ratio) to get the amount of chocolate chips required.

This is the same as multiplying 7/2 by the reciprocal of 7/3, which is 3/7. The sevens cancel out, and the result is 3/2, or one and one half (1 1/2) cups of chocolate chips required for the recipe.

To solve the given system of equations, one can utilize matrix operations, specifically finding the inverse of the coefficient matrix and multiplying it by the constants matrix to solve for the variables x, y, and z.

Solving a System of Equations

To solve the system of linear equations: 3x+4y+3z=5, 2x+2y+3z=5, and 5x+6y+7z=7, we can use methods such as substitution, elimination, or matrix operations. In this case, matrix operations may be more efficient for finding the values of x, y, and z.

Firstly, we must write the system of equations in matrix form (Ax = b), with A being the coefficient matrix, x the variable matrix, and b the constant terms matrix:

A =
| 3 4 3 |
| 2 2 3 |
| 5 6 7 |,
x =
| x |
| y |
| z |,
b =
| 5 |
| 5 |
| 7 |

Next, we find the inverse of matrix A, if it exists, and then multiply it by b to solve for x:

x = A-1 * b

Through matrix operations, we can find A-1. The existence of an inverse is dependent on the determinant of A not being zero. If the determinant is non-zero, the inverse can be used to compute the variables' values. Therefore, we proceed with calculating the determinant and, if possible, the inverse to solve for x, y, and z.

Finally, we multiply the inverse of A (if it exists) by b to get the values for x, y, and z. This involves algebraic steps and matrix multiplication. If any mistake is made, the process requires careful checking and rechecking.

Answer:

y = -3x - 1

Step-by-step explanation:

The slope intercept form of the equation of a line is:

y = mx + b

where m is the slope, and b is the y-intercept.

First, we find the slope of the line using the two given points.

m = slope = (y2 - y1)/(x2 - x1) = (2 - (-7))/(-1 - 2) = (2 + 7)/(-3) = 9/(-3) = -3

Now we plug in the slope we found into the equation above.

y = -3x + b

We need to find the value of b, the y-intercept. We use the coordinates of one of the given points for x and y, and we solve for b. Let's use point (2, -7), so x = 2, and y = -7.

y = -3x + b

-7 = -3(2) + b

-7 = -6 + b

Add 6 to both sides.

-1 = b

Now we plug in -1 for b.

y = -3x - 1

The probability that a first roll is an even number and a second role is a number greater than 4 when a six-sided number cube is rolled twice is 1/6.

The probability of an event is the fractional value determining how likely is that event to take place. If the event is denoted by A, the number of outcomes favoring the event A is n and the total number of outcomes is S, then the probability of the event A is given as:

P(A) = n/S.

When the occurrence of one event, doesn't affect the occurrence of the other event, then the two events are independent of each other.

If we have two independent events A and B, then the probability of A and B is given as:

P(A and B) = P(A) * P(B).

We are informed that a six-sided number cube is rolled twice. We are asked what is the probability that a first roll is an even number and a second roll is a number greater than 4.

Let the event of getting an even number on a first roll be A.

∴Number of outcomes favorable to event A (n) = 3 {2, 4, 6}

Total number of outcomes (S) = 6 {1, 2, 3, 4, 5, 6}

∴ The probability of getting an even number on a first roll is:

P(A) = n/S = 3/6 = 1/2.

Let the event of getting a number greater than 4 on a second roll be B.

∴Number of outcomes favorable to event B (n) = 2 {5, 6}

Total number of outcomes (S) = 6 {1, 2, 3, 4, 5, 6}

∴ The probability of getting a number greater than 4 on a second roll is:

P(B) = n/S = 2/6 = 1/3.

∵ Our two events, A and B, are independent of each other, that is, the occurrence of one doesn't affect the occurrence of the other, the probability that a first roll is an even number and a second roll is a number greater than 4 is given by:

P(A and B) = P(A)*P(B) = (1/2)*(1/3) = 1/6.

∴ The probability that a first roll is an even number and a second role is a number greater than 4 when a six-sided number cube is rolled twice is 1/6.

Step-by-step explanation:

a) Let x be the number of months.

1. The first phone costs $100 and $55 per month for unlimited usage, then for x months it will cost $55x and in total

$(100+55x)

2. The second phone costs $150 and $51 per month for unlimited usage, then for x months it will cost %51x and in total

$(150+51x)

3. If the second phone must be less expensive than the first phone, then

b) Solve this inequality:

55x-51x>150-100

4x>50

x>12.5

c) Sal's mother has to keep the second cell phone for at least 13 months (because x>12.5).
