<h2>Answer:</h2>

The graph which represent a graph of a function is:

        Graph A and Graph C

<h2>Step-by-step explanation:</h2>

We know that a graph of a function satisfies the vertical line test i.e. any line passing through the domain and parallel to y-axis should intersect the curve exactly once i.e. corresponding to each x-value there is exactly one y-value.

Hence, from the figure attached to the answer we see that the Graph which is a function is:

            Graph A and Graph C

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). A construction
charle [14.2K]

Answer:

y=\frac{11}{20}x+6

Step-by-step explanation:

Given:

Two points are given

x = number of minutes

y = length of the lin

(x_{1},y_{1} ) ⇒ (0, 6)

(x_{2},y_{2} ) ⇒ (20, 17)

We need to find the equation that represents the relationship between x, y.

Solution:

Using slope formula to find the slope of the equation of the line.

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Substitute (x_{1},y_{1} ) = (0, 6) and (x_{2},y_{2} ) = (20, 17) in above equation.

m=\frac{17-6}{20-0}\\m=\frac{11}{20}

So, slope of the line m = \frac{11}{20}

Using point slope formula.

(y-y_{1})=m(x-x_{1}) ------------(1)

Where, m = slope of the line

Substitute (x_{1},y_{1} ) ⇒ (0, 6) and m = \frac{11}{20} in equation 1.

(y-6)=\frac{11}{20} (x-0)

y-6=\frac{11}{20}x

Add 6 both side of the equation.

y-6+6=\frac{11}{20}x+6

y=\frac{11}{20}x+6

Therefore, the equation that represents the relationship between x and y is written as:

y=\frac{11}{20}x+6

MrMuchimi

Answer:

5.45 * 10^7

Step-by-step explanation:

(4.8 * 10^7) +6,500,000

= (4.8 * 10^7) + 6.5 * 10^6

= (4.8 * 10^7) + (0.65 * 10^7)

= 5.45 * 10 ^7

One root of a third degree polynomial function f(x) is -5 + 2i. Which statement describes the number and nature of all
Sauron [17]

Answer:

f(x) has two imaginary roots and one real root.

Step-by-step explanation:

Complex roots:

I a complex number a + bi is a root of a polynomial, it's conjugate a - bi is also a root.

One root of a third degree polynomial function f(x) is -5 + 2i.

This means that -5 - 2i is another root of the polynomial, and thus, 2 of the roots are complex.

Third degree, so it has three roots, which means that the third root is real(not possible to have a complex root without it's conjugate), and thus, the correct answer is:

f(x) has two imaginary roots and one real root.
