Answer:

f(-3) = -1/3

Step-by-step explanation:

-3 is less than -2 so we use the first function  1/x

f(-3) = 1/-3

Answer:

-1/3

Step-by-step explanation:

-3 is less than -2, so use the first one, 1/x and substitute -3 in

On a coordinate plane, a cube root function goes through (negative 8, negative 2), has an inflection point at (2.5, 0), and goes through (10, 2).

A coordinate plane is a two-dimensional plane formed by the intersection of a vertical line called the y-axis and a horizontal line called the x-axis. These are perpendicular lines that intersect each other at zero, and this point is called the origin.

On a coordinate plane, a cube root function goes through (negative 10, negative 2), has an inflection point at (negative 3, 0), and goes through (4, 2).

Answer and Step-by-step explanation:

The equation should look like this:

-9(x - 86) = x - 48

Distribute the -9.

-9x + 774 = x - 48

Add 48 and 9x to both sides of the equation.

822 = 10x

Divide both sides of the equation by 8.

82.2 = x

Use information about the triangle's perimeter, to find the side length of C.

If the triangle frame is a right triangle, than you could use the Pythagorean Theorem and use the following formula, a^2 + b^2 = c^2, to find the measure of side c.

Answer:

side-side-side

Step-by-step explanation:

If two pairs of corresponding angles in a pair of triangles are congruent, then the triangles are similar. We know this because if two angle pairs are the same, then the third pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion.

The similarity statement for the pair of triangles is triangle XYZ similar triangle ENW by AA similarity criterionand mathematically represented as: [tex]\Delta XYZ \, \sim \, \Delta ENW\\[/tex]

Given: In the figure, the angle YXZ is equal to angle NEW and the angle XZY is equal to angle ENW are marked in the corresponding triangles.

To prove triangle XYZ similar triangle ENW  by following steps:

Step 1: Consider the triangle XYZ and triangle ENW.

Compare the angle in both the triangles.

Step 2: Applying the AA similarity criterion:

The Angle-Angle AA similarity criterion states if two angles of one triangle is equal to the corresponding triangle, then two triangles are similar,

This implies triangle XYZ and triangle ENW by AA similarity criterion.

Therefore, the triangle XYZ and triangle ENW by AA similarity criterion. That is  [tex]\Delta XYZ \, \sim \, \Delta ENW\\[/tex]

====================================================

Work Shown:

Refer to the drawing below.

sin(angle) = opposite/hypotenuse

sin(17) = x/3.5

3.5*sin(17) = x

x = 3.5*sin(17)

x = 1.02330096652958

x = 1.0233

Be sure that your calculator is in degree mode.

Explanation:

The rule [tex](x,y) \to (x+4, y-5)[/tex] means we add 4 to the x coordinate and subtract 5 from the y coordinate.

The point (3,5) becomes (3+4, 5-5) = (7,0)

This shifts the point 4 units to the right and 5 units down.

Answer:

There are 25 students in the class.

Step-by-step explanation:

In order to find the number of students in the class, you can add the number of data points together. Because the name of each person will only be recorded once and only to one data value, that means by adding the total number of data points collected, you can find out the number of students in the sixth-grade class. There are three data points on 3, two data points on 4, five data points on 5, eight data points on 6, two data points on 7, one data point on 8, and four data points on 9, this means the total number of students will be 3 + 2 + 5 + 8 + 2 + 1 + 4 = 25 students, so this will be your answer.

Answer:

18.75 packs of sugar

Step-by-step explanation:

20/8 = 2.5 (how many 8 ounce bottles in 20 oz)

2.5 * 30 = 75 (to find how many grams of sugar in the 20 oz bottle)

75/4 = 18.75 (how many packs of sugar it's equal to)

you can also use a ratio to solve:

8/30 = 20/x; cross multiply

600 = 8x; divide 8 on both sides

x = 75

75/4 = 18.74 (how many packs of sugar it's equal to)

Answer:

f(x) has three real roots.

Step-by-step explanation:

f(x) has three real roots.

A third degree polynomial function with real coefficients has exactly 3 roots.

Furthermore, all complex roots come in pairs, either there is none, or there are exactly two conjugates, which are in the form e1+i(e2) and e1-i(e2) where e1 and e2 are polynomial expressions.

This also means that a third degree polynomial with real coefficients has at least one real root, or three.

Since we are given two real roots for the given polynomial, the third root cannot be complex alone, so the only possibility is that there are three real roots.

If b is real, then all three roots are real.

If b is not real, then two of the roots are real (-4 and 4) and one is imaginary.

Polynomial is an equation written with terms of the form kx^n.

where k and n are positive integers.

There are quadratic polynomials and cubic polynomials.

Example:

2x³ + 4x² + 4x + 9 is a cubic polynomial.

4x² + 7x + 8 is a quadratic polynomial.

We have,

The polynomial function f(x) has degree 3 and two roots -4 and 4, we know that (x + 4) and (x - 4) are factors of the function.

To see why, note that when x = -4, the factor (x + 4) becomes zero, making the function zero.

Similarly, when x = 4, the factor (x - 4) becomes zero, making the function zero.

Now,

Since the function has degree 3 and two factors of degree 1, we can conclude that the third factor is also of degree 1.

This means that the function can be written in the form:

f(x) = a (x + 4) (x - 4) (x - b)

where a and b are constants.

We don't know the value of b, but we know that it is a real number (since the other two roots are real).

Thus, the three roots of the function are -4, 4, and b.

Now,

To determine whether the roots are all real or some are imaginary, we need to know the value of b.

If b is real, then all three roots are real.

If b is not real, then two of the roots are real (-4 and 4) and one is imaginary (b).

Thus,

If b is real, then all three roots are real.

If b is not real, then two of the roots are real (-4 and 4) and one is imaginary.

Answer:

The volume of box Y is 1/64 of the volume of box X

Step-by-step explanation:

Since. The edge of a box Y is 1/4 the lengtj of box X ;

The volume is 3 dimensional and each dimension of Y is 1/4th the dimension of X

The volume of Y will be (1/4)^3 the volume of Y

(1/4)^3 = 1/4 * 1/4 * 1/4 = 1/64

For instance, if edge of X = 8

Edge of Y which is 1/X ; edge Y = 1/4(8) = 2

Volume, X 8^3 = 512

Volume Y = 2^3 = 8

8/512 = 1 / 64
