Test for symmetry about the x-axis: Replace y with (-y). Simplfy the equation. If the resulting equation is equivalent to the original equation then the graph is symmetrical about the x-axis. Example: Use the test for symmetry about the x-axis to determine if the graph of y - 5x2 = 4 is symmetric about the x-axis. Hoped this helped! :)

What is the volume of the prism? Enter your answer in the box as a mixed number in simplest form.
Musya8 [376]
The volume prism refers to the number of cubic units that will exactly fill the figure. The volume of a rectangular prism can be found or calculate by using the formula V=Bh, where B represents to the area of the base or in other words the length and width of the rectangle.

In this exercise is given that the measurements of a prism are 2ft, 3/2ft, and 3/2ft; and it is asked to find its volume. In order to find the volume of the prism, you should substitute the given values into the previous mention formula.
V=Bh
V=(2ft)(3/2ft)(3/2ft)
V=9/2ft^3 or 4 1/2ft^3

The volume of the prism is 4 1/2ft^3 as a mixed number.

What is the point-slope equation of a line with slope -5 that contains the point (6,3)
Luden [163]

Answer:

y-3=-5(x-6)

Step-by-step explanation:

we know that

The equation of the line into point-slope form is equal to

y-y1=m(x-x1)

we have

m=-5

(x1,y1)=(6,3)

substitute

y-3=-5(x-6) ----> equation of the line into point-slope form

The population of the city of Miami is approximately 463,300 and is increasing at a rate of 3% each year. Use an exponential fun
Tatiana [17]
<h2>Answer:</h2><h2>The population of the city after 7 years = 569,859</h2>

Step-by-step explanation:

The population of the city of Miami = 463,300

The rate of increase in population every year = 3%

The population of the city after 7 years = ?

By formula, P_{n} = P (1 +\frac{r}{100})^{n }

Pn is the population after 7 years

P is the current population = 463,300

r = 3 %, n = 7

P_{7} = 463300 (1 +\frac{3}{100})^{7 }

= 463300 (1.23)

= 569859

The population of the city after 7 years = 569,859

Given that B is between A and C. If AB=x, BC =2x-3, and AC = 30. Find x and bc
Artemon [7]

Answer:

x=11

BC=19

Step-by-step explanation:

AB+AC=AC this is because B is in between A and C. So now we can substitute all of the line segments, so we have

x+2x-3=30          Now you add 2x and x

3x-3=30      Now you add 3 to both sides so you can get 3x alone on one side

3x=33        Now you divide both sides by 3 so you get the x alone on one side

x=11

The next step is to substitute x to find BC.

BC=2x-3       Substitute the x with 11

BC=2(11)-3    Then multiply 2 and 11 because that is the rule with parenthesis

BC=22-3        then subrtact the 3 from 22

BC=19

You can check your work by doing AB+BC=AC

11+19=30        substitute your answers and then add them together

30=30
