What are the solutions of the equation (5x –
- 2)(x + 6) = 0?

Answer:

39

Step-by-step explanation:

6a - b = 6 x 8 - 9 = 48 - 9 = 39

Answer: 39

Step-by-step explanation:

Given that a=8 and b=9

The expression is 6a-b

That is; we have to find 6 times a and then subtract b from it.

6a = 6*8=48

b=9

6a-b=48-9=39

Therefore the answer to the question is 39.

Answer:

tan30° = [tex]\frac{5}{12}[/tex]

Step-by-step explanation:

tan30° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{5}{12}[/tex]

Answer:

[tex]\dfrac{5}{12}[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{9.4 cm}\underline{Trigonometric ratios} \\\\$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

From inspection of the given right triangle:

Substitute the values into the tan trigonometric ratio:

[tex]\implies \tan(30^{\circ})=\dfrac{5}{12}[/tex]

Step-by-step explanation:

The resultant of subtraction of both vectors is

|r - s| = √(r² + s² - 2rscos{15})

A vector is an object that has both a magnitude and a direction.

Given is that |r| = 6 at an angle of 30° and |s| = 11 at an angle of 225°.

For the subtraction of vectors, we can write its magnitude as -

|r - s| = √(r² + s² - 2rscos{15})

Therefore, the resultant of subtraction of both vectors is

|r - s| = √(r² + s² - 2rscos{15})

Answer:

A. Frame

Step-by-step explanation:

This is because it does not contain the who population and it is the place where the participants of the experiment are selected. It is not the control group because this includes people who were not even in the experiment.

The list of test takers represent the frame.

A frame consist of everyone in the population that has a chance of being picked.

The population represents the individuals that the researchers is interested in conducting the research on. The population of a study has similar characters.

The sample is the person that's selected from the population and represents the population as a whole.

The control group refers to the people that didn't partake in the experimentation carried out.

Therefore, the 50 test takers from the list represents the frame.

In conclusion, the  correct option is A "frame".

The combined mass of the compounds is 13/12 grams

From the question, we have the following parameters that can be used in our computation:

3/4 gram sodium chloride and 1/3 gram potassium chloride

The combined mass of the compounds is then calculated as

Combined mass = sodium chloride + potassium chloride

Substitute the known values in the above equation, so, we have the following representation

Combined mass = 3/4 + 1/3

Evaluate the sum

Combined mass = 13/12

Hence, the combines mass is 13/12 grams

Answer/Step-by-step explanation:

1. The vertex of am angle is formed when two lines join together. The vertex of the angle shown in the diagram is located outside the circle.(<R)

2. The lines that created <FRT (lines FR & TR) are secants

3. The major arc = FT = 140°

minor arc = QS = 44°

4. Formula of Exterior angles of a circle = (major arc - minor arc)/2

x = (140 - 44)/2

x = 96/2

x = 48°

Answer: Her total earnings would be $28+$54=$82.

Step-by-step explanation:

Lori's base salary is calculated by multiplying her hourly rate by the number of hours she works. If Lori works 4 hours on a Tuesday and earns $7/hr, her base salary would be 4*$7=$28.

Lori's tips are calculated as 18% of her food sales. If Lori has $300 of food sales on a Tuesday, her tips would be 18%*$300=$54.

Lori's total earnings for the day would be the sum of her base salary and her tips. In this case, her total earnings would be $28+$54=$82.

Answer:

They are not inverse functions

Step-by-step explanation:

Given

[tex]f(x) = 5x[/tex]

[tex]f^{-1}(x) = x[/tex]

Required

Determine if both are inverse functions

First calculate the inverse of f(x)

[tex]f(x) = 5x[/tex]

Replace f(x) with y

[tex]y = 5x[/tex]

Swap x and y

[tex]x = 5y[/tex]

Make y the subject

[tex]y = \frac{1}{5}x[/tex]

Replace y with f-1(x)

[tex]f^{-1}(x) = \frac{1}{5}x[/tex]

By comparison:

[tex]f^{-1}(x) = x[/tex] and [tex]f^{-1}(x) = \frac{1}{5}x[/tex] are not the same:

Hence:

[tex]f(x) = 5x[/tex] and [tex]f^{-1}(x) = x[/tex] are not inverse functions

All you have to do is solve this by using substitution or elimination. or in this case, because we don’t have a second equation, we would solve the x-intercept and y-intercept

X=-12

Y=-9

Answer:

Step-by-step explanation:

A line that shows the number of hair barrettes she makes and the total number of beads she uses is y = 75x.

In order to put the equation in y-intercept (y=mx+b) form and determine the equation of a graphed line, you must first determine the slope and y-intercept. The slope is the ratio of the change in y to the change in x. Find two locations on the line, and then draw a sloping triangle joining them.

A line is a perfectly straight, one-dimensional figure that extends infinity in both directions and has no thickness. To stress that a line has no "wiggles" anywhere along its length, it is sometimes referred to as a straight line or, more archaically, a right line.

Two points on the line are (2, 150) and (5, 375)

y - 150 = ( (375-150) / (5-2) )  (x-2)

y - 150 = 75 (x-2)

y = 75x

Equation of line is y = 75x
