Sophie uses 18 beads to make a necklace. Three-sixths of the beads are purple. How many beads are purple? 6 9 12 15
Answer:
9
Step-by-step explanation:
If 3/6 of the 18 beads are purple we need to simplify 3/6. 3/6 is the same as 1/2. And 1/2 of 18 is 9.

Answer:[tex]\frac{-5}{4}, \frac{3}{4}[/tex]
Step-by-step explanation:
Given
[tex]\theta[/tex] is in the third quadrant and
[tex]\Rightarrow \cos \theta=\frac{-3}{5}[/tex]
tan and cot is positive in the third quadrant and the rest are negative
using identity
[tex]\sin^2 \theta+\cos^2 \theta=1\\\Rightarrow \sin \theta=-\sqrt{1-\cos^2 \theta}\\\Rightarrow \sin \theta =-\sqrt{1-(-\frac{3}{5}^2)}\\\Rightarrow \sin \theta =-\frac{4}{5}\\\Rightarrow\text{cosec} \theta=-\frac{5}{4}\\\Rightarrow \cot \theta=\frac{\cos \theta}{\sin \theta}=\frac{\frac{-3}{5}}{\frac{-4}{5}}=\frac{3}{4}[/tex]

The diameter of the circular railroad crossing sign below is 16 inches. Find the area of the sign. Use 3.14 for π.
A=πr2=π×r×r i well give you 15 points
Answer:
200.96
Step-by-step explanation:
Area is
[tex]\pi {r}^{2} [/tex]
Where r is the radius, we can find the radius since the radius is half of the diameter. Since the diameter is 16, the radius is 8. Now let plug it in the equation.
[tex]\pi(8) {}^{2} [/tex]
Which equals
[tex]64\pi[/tex]
Use 3.14 as pi then multiply
[tex]64 \times 3.14[/tex]

Plot the x-intercept(s), y-intercept, vertex, and axis of symmetry for the function below.
g(x) = x^2 + 4x + 3
Answer:
Step-by-step explanation:
Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Vertex: ( − 2 , − 1 )
Focus: ( − 2 , − 3/ 4 )
Axis of Symmetry: x = − 2
Directrix: y = − 5 /4
x-intercept is -1
y-intercept is 3
vertex is (-2, -1)
axis of symmetry is x = -2
What is Coordinate Geometry?One of the most intriguing ideas in mathematics is called coordinate geometry.
As per the given data:
We have to find out the x-intercept(s), y-intercept, vertex, and axis of symmetry for the function g(x) = x² + 4x + 3
For finding the graph of the given function, we must know its zeroes.
x² + 4x + 3 = 0
x² + 3x + x + 3 = 0
x(x+3) + 1(x+3) = 0
(x + 1)(x+3) = 0
The zeroes are -1 and -3.
The graph will be parabola in shape, as it is a quadratic equation.
From the graph:
x-intercept is -1
y-intercept is 3
vertex is (-2, -1)
axis of symmetry is x = -2
Hence, the values are as follows:
x-intercept is -1
y-intercept is 3
vertex is (-2, -1)
axis of symmetry is x = -2
