1. y = -1 is a horizontal line and intercepts the y axis at (0,-1). Because it is horizontal it does not intercept the x-axis. 2. X = -1 is a vertical line that intercepts the x axis at (-1,0). Because it is vertical it does not have a y-intercept

The range is the y values that result from using the x values from the domain. Since one of the x values is -3, substitute this in the equation. f(-3) = 3(-3) - 5 = -9 - 5 = -14. -14 is the first number in the range. Do the same for the other two numbers.

This one is hard to answer without showing you a picture but here goes. The line from the top of the 10m pole to the base of the 70m pole is the hypotenuse of a right triangle. Dropping a vertical line from the point of intersection forms a second triangle on the end that is similar to the original and the sides are proportional. Label the vertical line z and the horizontal line x. You can make a proportion now from the two triangles. 10/100 = z/x. In a similar way a proportion can be made with the 70m pole. The vertical would still be z but the horizontal could be y which will make the proportion 70/100 = z/y. Cross multiplying the proportions gives 10x=100z and 70y=100z. Since both 10x and 70y are equal to 100z they are equal to each other BUT y = 100-x. With substitution you get 10x=70(100-x). Solve this equation for x then substitute the answer in the very first equation to find z. z is the height you want.

5/2 is the answer and if it need to be broken down here is the answer 2.1 = 2

Twenty students randomly assigned to an experimental group receive an instructional program; 30 in a control group do not. After 6 months, both groups are tested on their knowledge. The experimental group has a mean of 38 on the test (with an estimated population standard deviation of 3); the control group has a mean of 35 (with an estimated population standard deviation of 5). U

the correct answer is 3 4(5n-7) = 10n+2 20n-28 = 10n+2 20n= 10n+30 10n=30 n=3

What is the volume of my previous question? Anyone?? 👻

My answer is B

thank you and sue does the thesis at the end of my 8 sentence paragraph sound okay . A good citizen is a great for society. She or he feels that she/he has certain responsibilities towards the state, the responsibilities of being loyal and honest. just as the state has certain responsibilities towards him. Although, she /he is aware of the privileges and his or her duties A good citizen takes intelligent interest in politics, so that she or he may use his or her vote for the good of the country and the nations.

sorry here is the correct one A good citizen is a great for society. She or he feels that she/he has certain responsibilities towards the state, the responsibilities of being loyal and honest. just as the state has certain responsibilities towards him. Although, she /he is aware of the privileges and his or her duties A good citizen takes intelligent interest in politics, so that she or he may use his or her vote for the good of the country and the nations. All Americans vote some say it’s not worth it does that mean there not a good citizen .
