How to find the slope?

The slope, or steepness, of a line is found by dividing the vertical change (rise) by the horizontal change (run) . The formula is slope =(y₂ - y₁)/(x₂ - x₁), where (x₁, y₁) and (x₂, y₂) are the coordinates of two points on the line.

What is a graph of a quadratic function called?

The graph of a quadratic function is a U-shaped curve called a parabola .

How to find slope with 3 coordinates?

If all 3 points are on the same line, then you only need to use 2 of them in the slope formula. If they are not on the same line, then you will have to carry out the slope equation 3 times, 1 for each pair of coordinates because they will create 3 different lines. Remember that the slope equation is (y 2 - y 1 )/(x 2 -x 1 ) .

How to simplify square roots?

Simplifying a Square Root Step 1: Find the prime factors of the number inside the radical sign. Step 2: Group the factors into pairs. Step 3: Pull out one integer outside the radical sign for each pair. Leave the other integers that could not be paired inside the radical sign.

The other method to find the vertex of a parabola is as follows: We know that the x-coordinate of a vertex, (i.e) h is -b/2a. Now, substitute the x-coordinate value in the given standard form of the parabola equation y=ax 2 +bx+c, we will get the y-coordinate of a vertex .

How to find discriminant?

Steps for Finding the Discriminant of a Quadratic Equation Step 1: Identify the values of a, b, and c in the quadratic equation. Step 2: Substitute the values of a, b, and c into the quadratic formula. Step 3: Evaluate the discriminant, b 2 − 4 a c , which is the expression under the radical.

What does r mean in domain and range example?

Let the constant function be f(x) = k. The domain of a constant function is given by ℝ, that is, the set of real numbers . The range of a constant function is given by the singleton set, {k}. The domain and range of a constant function is given as domain = ℝ and range = {k}, which is a singleton set.

Where is the axis of symmetry located?

The axis of symmetry always passes through the vertex of the parabola . The -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y = a x 2 + b x + c , the axis of symmetry is a vertical line x = − b 2 a .

How to express f in standard form?

The quadratic function f(x) = ax² + bx + c = 0 is said to be in standard form, wherein a (coefficient of x²) is not equal to zero. If a is positive, the parabola of the graph will open upward but if it is negative, it will open downward.

How do you find an equation with a slope?

These are the two methods to finding the equation of a line when given a point and the slope: Substitution method = plug in the slope and the (x, y) point values into y = mx + b, then solve for b . Use the m given in the problem, and the b that was just solved for, to create the equation y = mx + b.

What is the formula for the slope rule?

The slope can be calculated using the coordinates of two points using the formula, m = (y 2 - y 1 )/(x 2 - x 1 ) , where (x 1 , y 1 ) and (x 2 , y 2 ) are the coordinates of the two points lying on the line.

The missing expressions to the empty blanks are 2x, 2x - 1, x - 1 and x + 3.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Sum of each row = sum of each column = x + 2 + x + 2 = 2x + 4

Hence:

a + x + 2 + 2 - x = 2x + 4

a = 2x

b + 5 - x + x = 2x + 4

b = 2x - 1

c + 5 - x + 2x = 2x + 4

c = x - 1

d + 2 + x - 1 = 2x + 4

d = x + 3

The missing expressions to the empty blanks are 2x, 2x - 1, x - 1 and x + 3.

In 2005, 12.2 out of every 50 employees at a company were women. If there are 48,744 total company employees, estimate the number of women.

Answers

Answer:

12000

Step-by-step explanation:

Using this information, you can make a ratio: 12.2/50 = x/48744

By simplifying this ratio you get that 50x = 594676. Dividing both sides by 50 you get about 11900, which you can round up to 12000

Answer:

11,894 women

Step-by-step explanation:

ratio of women to employees = 12.2 : 50

Let x = number of women employees to 48744 employees

12.2 : 50 = x : 48744

⇒ 12.2 / 50 = x / 48744

⇒ 0.244 = x / 48744

⇒ x = 0.244 · 48744

⇒ x = 11893.536

⇒ x = 11894 (nearest whole number)

Therefore, there are approximately 11,894 women in a company with a total of 48,744 employees

An isosceles triangle has an angle that measures 38degrees. What measures are possible for the other two angles? Choose all that apply.

Answers

Answer:

71° and 71°.

⠀

Step-by-step explanation:

The triangle having two sides equal along with one different side is called an isosceles triangle.

⠀

So, Let us assume the other sides (two equal sides) of the isosceles triangle as x. As the different side is already given in the question.

⠀

We know that,

The sum of all angles of a triangle is 180°

⠀

So, According to the question :

⠀

[tex]{\longrightarrow \it\qquad { \ { { 38 \: }^{ \circ} + x + x = 180{}^{ \circ} }}}[/tex]

⠀

[tex]{\longrightarrow \it\qquad { \ { { 38 \: }^{ \circ} + 2x = 180{}^{ \circ} }}}[/tex]

⠀

[tex]{\longrightarrow \it\qquad { \ { 2x = 180{}^{ \circ} - { 38 \: }^{ \circ}}}}[/tex]

⠀

[tex]{\longrightarrow \it\qquad { \ { 2x = 142{}^{ \circ} }}}[/tex]

⠀

[tex]{\longrightarrow \it\qquad { \ { x = \dfrac{142{}^{ \circ}}{2} }}}[/tex]

⠀

[tex]{\longrightarrow \it\qquad { \pmb { x = 71^{ \circ} }}}[/tex]

⠀

Therefore,

The measure of the two other angles of the isosceles triangle are 71° and 71°.

Maybe mark brainiest

Dime = 10 cents

Nickel = 5 cents

Total value of coins = 3(10) + 4(5) = 30 + 20 = 50

To find the percent, first create a fraction. The fraction will be the amount of money that Benjamin has over the total (one dollar).

50 / 100 = 5 / 10 = 0.5

0.5 x 100 = 50

Answer:

x = 10.8

Explanation:

[tex]\sf \sf cos(x)= \dfrac{adjacent}{hypotensue}[/tex]

using cosine rule:

[tex]\rightarrow \sf cos(26)= \dfrac{x}{12}[/tex]

[tex]\rightarrow \sf x = cos(26) *12[/tex]

[tex]\rightarrow \sf x =10.8[/tex]

Answer:

The answer is rounded 10.8

Step-by-step explanation:

Cosine is the adjacent side over the hypotenuse, or a/h. So, cos 26=x/12. To solve for x, isolation of the variable is necessary. If both sides are multiplied by 12, the equation becomes 12 (cos 26)=x. The cosine of 26 is 0.8988, which multiplied by 12 is 10.8.

B. 8(6x) + 9
C. 14x + 17
D. 48x + 17
E. 48x + 72

Answers

Answers: Choice A and Choice E

Explanation:

The distributive property allows us to go from the original expression to choice A. We multiply the outer term 8 by each term inside the parenthesis.

In general, the distributive property is a(b+c) = ab+ac. Example: 2(3+4) = 2(3)+2(4) = 6+8 = 14.

After simplifying the expression in choice A, it leads directly to choice E. This is because 8(6x) = 48x and 8(9) = 72.

Side note: A common mistake students do is to multiply the outer term by only one of the terms inside the parenthesis, while forgetting about the other term inside. Choice B shows this mistake. It's possible your teacher put choice B in there as a trap/trick answer.
