Answer:

Step-by-step explanation:

Simplify inside the parentheses by dividing coefficients, subtracting the exponents on like bases, and raising the resulting expression to the –3 power. Then, write bases with positive exponents.

Raise the numerator and denominator to the –3 power. Then, using the power of a power property, multiply the exponents. Divide the coefficients and subtract the exponents on like bases, then write with positive exponents

Answer:

D.120

Step-by-step explanation:

The sides AB and AC are equal and thus the angles they form with BC should be equal . Since now angle ABC is 30 then application of sum of angles in a triangle as a constant(180 degrees) we can subtract 60 degrees from it which gives 120

The result of the given subtraction problem of expression will be -3a³ + 5a² - 3a + 7.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given expression,

(a³ - 2a + 5) - (4a³ - 5a² + a - 2)

⇒ a³ - 4a³ - 2a - a + 5a² + 5 + 2

⇒ -3a³ + 5a² - 3a + 7

Hence "The result of the given subtraction problem of expression will be -3a³ + 5a² - 3a + 7".

Answer:

the table that has the same additive rate of change. so you subtract the last number to the one before it.  to get the rate of change but you need to the same with every number in the y values.

Step-by-step explanation:

for example if the table has 1,2,3,4 point with the y values with 2, 4, 6,8. so you will get 8-6=2 then you repeat: 6-4=2, 4-2=2. when they are the same meaning its a linear function.

Answer:

y = -2x + 1

Step-by-step explanation:

First we're going to find the gradient (the number in the green box with the question mark).

We use the formula [tex]\frac{y2-y1}{x2-x1}[/tex] to calculate the gradient.

Let's make (-1, 3) be our (x1, y1), and (2, -3) be our (x2, y2).

Substitute the points into our formula:

gradient = [tex]\frac{(-3)-3}{2- (-1)}[/tex]

gradient = [tex]\frac{-6}{3}[/tex]

gradient = -2

Next, we're going to find the y-intercept (the number in the grey box)

Now that we have the gradient, our equation looks like this:

y = -2x + c

We use the letter c to represent the y-intercept of a linear graph.

Substitute one of the points given into the x and y in the equation. Let's use (-1, 3).

3 = -2(-1) + c

3 = 2 + c

c = 1

So our equation is y = -2x + 1

Answer:

3/35

Step-by-step explanation:

Here, we want to know the constant of proportionality in this direct variation scenario

Since it is a direct variation, the form we are having would be;

x = ky

where x and y directly vary with each other and k is the constant of proportionality

Now, for the first relation

3 = 35k

for the second

9 = 105k

Thus k would be

3/35 which is the same as 9/105

Kindly note that 9/105 can be reduced to 3/35

So linking the number of weeks to the number of stamps collected, the constant of proportionality is 3/35

The answer is A.) y =35/3x

Answer: A and E

Step-by-step explanation:

A. Correct

You know this is an isisceles triangle because of the markers on the sides. The markers mean the sides are equal. Also, the lengths are both 8.

B. Incorrect

A scalene triangle is a triangle where all 3 sides have different lengths. The picture shows an isosceles triangle.

C. Incorrect

Even is this may seem like an acute triangle because of the 45°, but this is actually not an acute triangle. An acute triangle requires for all its sides to be less than 90°. The right angle at the bottom right is 90°, not less than.

D. Incorrect

An equilateral triangle has 3 equal sides. The 3 sides in thsi triangle are not equal.

E. Correct

This is a right triangle. You can tell by the right angle label on the bottom right.

F. Incorrect

An obtuse triangle has an angle that is greater than 90°. No angle on this triangle is larger than 90°.

Answer:

(a^2+5)(a^2-7)

Step-by-step explanation:

Answer:

The x-intercept is (-9,0). The y-intercept is (0,27).

Step-by-step explanation:

9x - 3y = -81

-9x         -9x                  Subtract 9x from both sides

-3y = -9x - 81                Divide both sides by -3

y = 3x + 27

I graphed the equation below.

Step-by-step explanation:

9x-0=-81

divide all through with 9x to get

x=-2

0-3y=-81

divide all through with 3y to get

y=27

Step-by-step explanation:

To multiply matrices, the number of columns in the first matrix must equal the number of rows in the second matrix.

Matrix A has 2 columns.

Matrix B has 2 rows.

So the matrices can be multiplied.

Matrix A has 2 rows.  Matrix B has 1 column.  So the result will also have 2 rows and 1 column.

The first row is (5)(2) + (2)(3) = 16.

The second row is (3)(2) + (-1)(3) = 3.

According to the question,

Given

Function[tex]f(x)= 3x-6[/tex]

[tex]f(x)= 3x-6[/tex] is function in one variable x with highest exponent 1.

Therefore, it is a linear function.

Represents the straight line.

x increases y also increases.

No maximum and minimum point.

Compare it with general equation of line [tex]y = mx + c[/tex]

Slope of the line [tex]= 3[/tex]

Answer:

0.7

Step-by-step explanation:

The probability that the number is in set A’ is the probability that a number is not in set A.

From the venn diagram attached below, they are two sets, set A and set B. Set A has 3 elements {15, 12 18}, Set B has 5 elements {12 18 10 14 16}.

The total number of elements in the universal set is 10 i.e {10 11 12 13 14 15 16 17 18 19}

therefore the number of elements in set A' is 7, i.e {10 11 13 14 16 17 19}.

the probability that the number is in set A’  = number of elements in set A'/number of elements in the universal set

probability that the number is in set A’ = 7 / 10 = 0.7

Answer:

  1.  The angles do not have the same reference angle

Step-by-step explanation:

The angles are in the 2nd and 4th quadrants, so both have tangents with a negative sign. (This eliminates choices 2, 3, 4.)

The angles do not have the same reference angle.

_____

5π/6 has a reference angle of π/6.

5π/3 has a reference angle of π/3.

Answer:

The angles do not have the same reference angle.

Step-by-step explanation:

2π = 360°

π = 180°

5π/6 = [tex]\frac{5 * 180}{6}[/tex] = 150° (The reference angle here is 180° - 150° = 30°

5π/3 = [tex]\frac{5 * 180}{3}[/tex] = 300° (The reference angle here is 360° - 300° = 60°)

The reference angles are not the same and so the value of their tangents are not equal.

Answer:

Option B is correct

Step-by-step explanation:

Given: [tex]\left | p \right |=7\sqrt{2}\,,\,\left | p+q \right |=12\sqrt{3}[/tex]

To find: interval on which [tex]\left | q \right |[/tex] must fall

Solution:

[tex]\left | p \right |=7\sqrt{2}\\-7\sqrt{2}\leq p\leq 7\sqrt{2}\,\,(i)[/tex]

[tex]\left | p+q \right |=12\sqrt{3}\\-12\sqrt{3}\leq p+q\leq 12\sqrt{3}\,\,(ii)[/tex]

Subtract (ii) from (i)

[tex]-12\sqrt{3}+7\sqrt{2}\leq p+q-p\leq 12\sqrt{3}-7\sqrt{2}\\-12\sqrt{3}+7\sqrt{2}\leq q\leq 12\sqrt{3}-7\sqrt{2}\\\left | q \right |=12\sqrt{3}-7\sqrt{2}[/tex]

So, [tex]\left | q \right |[/tex] must fall in interval [tex][12\sqrt{3}-7\sqrt{2},\infty)[/tex]

Therefore, option B is correct.
