Answer:
2 units
Step-by-step explanation:
the radius is always half the diameter
d = 2r
F(x)= (x+13)(x-2) in expanded form, it would be x^2+11x-26
Answer:
D is false
Step-by-step explanation:
f(x) = -2x2 + 4x + 6 should be written with a " ^ " to indicate exponentiation:
f(x) = -2x^2 + 4x + 6.
Because of the - sign, we know that the graph of this function opens down, so there is a maximum at the vertex. We can determine the x-value at the vertex by using the formula x = -b/(2a), which here is x = -4/(2*-2), or 1.
Evaluating f(x) = -2x^2 + 4x + 6 at x = 1, we get -2 + 4 + 6, or 8. So statement A is true: there's a max at (1, 8). This is also the vertex of the graph.
Let's now look at C and D. We evaluate f(x) at x = 3 and x - 2. If the output (y) value is 0, we know we have an x - intercept:
f(3) = -2(9) + 4(3) + 6 = 0. Yes, C is true, (3, 0) is an x-intercept.
f(-2) = -2(4) - 8 + 6 is not 0. Therefore D is false; (-2, 0) is not an x-intercept.
Look at B: Let x = 0 and find y: it's 6. Thus, (0, 6) is the y-intercept. B is true.
Answer:
12y + 120
Step-by-step explanation:
<u>First of, what is the distributive property?</u>
The distributive property is the property that helps distribute numbers under the parenthesis.
For example, lets use {x+1}4. You distribute the 4 towards the x and the one like this:
4(x) + 1(4)
4x + 4
Now, let's go back to your problem
<u>Solution:</u>
{y+10}12
12(y) +12(10)
= 12y + 120

Using the scatter plot, it is found that 4 visitors were there during the fourth hour.
<h3>What is a scatter plot?</h3>
- A scatter plot is similar to a function graph, as for each value of x, it will have the corresponding value of y.
Researching the problem in the internet, it is found that:
- The values of x represents each hour.
- The corresponding y-value represents the number of visitors during hour x.
- In the plot, we have that when x = 4, y = 4, hence, 4 visitors were there during the fourth hour.
