Rhian sat a math test and an english test.In the maths test she scored 14 out of 17.In the english test she scored 31 out of 39.

Dvinal [7]

Answer:

The maths test

Step-by-step explanation:

If you convert both of the results to percentage,

Maths:

$\frac{14}{17} \times 100 = 82\%$

English:

$\frac{31}{39} \times 100 = 79\%$

You'll see that she scored better in the maths test.

The degree of the polynomial function f(x) is 4.

Leto [7]

See the graph below

<h2>Explanation:</h2><h2></h2>

A polynomial function whose degree is 4 is given by the form:

$f(x)=ax^4+bx^3+cx^2+dx+e \\ \\ Or: \\ \\ f(x)=a(x-x_{1})(x-x_{2})(x-x_{3})(x-x_{4}) \\ \\ \\ Where: \\ \\ x_{1},x_{2},x_{3} \ and \ x_{4} \ are \ the \ roots$

Here the roots are:

$x_{1}=-8 \\ \\ x_{2}=-5 \\ \\ x_{3}=1 \\ \\ x_{4}=2$

If we set $a=1$ then:

$f(x)=(x+8)(x+5)(x-1)(x-2)$

Finally, by using graphing tool we get the graph of our polynomial function:

A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function?

mamaluj [8]

Answer:

Option C. $y=(3/4)x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

so

Find the value of the constant k

For the point (-8,-6)

$k=y/x=(-6/-8)=3/4$

For the point (12,9)

$k=y/x=(9/12)=3/4$

<u><em>Note</em></u> A single point was required to find the constant k (because the line passes through the origin)

The equation is equal to

$y=(3/4)x$

In ΔNOP, OP = 7, PN = 13, and NO = 19. Which statement about the angles of ΔNOP must be true?

zmey [24]

The angles must be acute and all the measured angles must be different.

<h3>What is a triangle?</h3>

This a shape with 3 sides and angke

If in ΔNOP, OP = 7, PN = 13, and NO = 19, then the measure of the angles must be different as well;

Hence the statement that must be true about the angles is that the angles must be acute and all the measured angles must be different. The given triangle must also be a scalene triangle
