Select the correct answer from each drop-down menu.
finlep [7]

Answer:

Coordinates of point B are (10,-4)

Coordinates of point D are (3.6,-0.4)

Step-by-step explanation:

1) Point C(3.6, -0.4) divides in the ratio 3 : 2. If the coordinates of A are (-6, 5), the coordinates of point B are ____

Let the coordinates of B be (x_2,y_2)

Coordinates of A =(x_1,y_1)=(-6,5)

Coordinates of C=(x,y)=(3.6,-0.4)

We will use section formula over here

x=\frac{mx_2+nx_1}{m+n} , y = \frac{my_2+ny_1}{m+n}

m:n=3:2

3.6=\frac{3x_2+2(-6)}{3+2} , -0.4=\frac{3y_2+2(5)}{3+2}3.6 \times 5 = 3x_2-12, -0.4 \times 5 = 3y_2+10\\18+12=3x_2 , -2=3y_2+10\\30=3x_2 , -12=3y_2\\10=x_2, -4=y_2\\

Coordinates of B = (10,-4)

2)If point D divides in the ratio 4 : 5, the coordinates of point D are ____

(fraction)

Let the coordinates of D be (x,y)

Coordinates of A =(x_1,y_1)=(-6,5)

Coordinates of B=(x_2,y_2)=(10,-4)

We will use section formula over here

x=\frac{mx_2+nx_1}{m+n} , y = \frac{my_2+ny_1}{m+n}

m:n=3:2

x=\frac{3(10)+2(-6)}{3+2} , y=\frac{3(-4)+2(5)}{3+2}\\x=3.6,y=-0.4

Coordinates of point B are (10,-4)

Coordinates of point D are (3.6,-0.4)

If I get a 55.6% on a test an the test is worth 80% what is my grade on that test A,B,C,D,F
Fittoniya [83]

If you got 55.6% on a test and that test is worth 80%

So first let us calculate the actual percentage that you scored.

The actual percentage is

\begin{gathered} \frac{0.556}{0.80}=0.695 \\ 0.695\times100=69.5\% \end{gathered}

So your actual score on the test is 69.5%

The grading system varies across countries and states

The traditional grading scale is given below

90% to 100% corresponds to A grade.

80% to 89% corresponds to B grade.

70% to 79% corresponds to C grade.

60% to 69% corresponds to D grade.

0% to 59% corresponds to F grade.

69.5% can be rounded off to 70%

Therefore, 69.5% corresponds to C grade.

(note: the above grade is not valid in case your school follows a different grading scale)

5 points<br> Write the polynomial 5x + 2x3 + 8x2<br> 7 in standard form.
artcher [175]

Find the GCF, then factor it out. Finally, simplify each term in the parentheses.

5x + 2x3 + 8x2

x(\frac{5x}{x}+\frac{2x^3}{x}+\frac{8x^2}{x} )

x(5+2x^2+8x)
