Point B is collinear with A and C and partitions AC in a 3:4 ratio. B is located at (4,1) and C is located at (12,5). Find the c
GrogVix [38]

Answer:

A(-\frac{20}{3} ,-\frac{13}{3})

Step-by-step explanation:

Point B partitions AC in a 3:4 ratio.

B is located at (4,1) and C is located at (12,5).

Let (x_1,y_1) be the coordinates of A.

Then (\frac{mx_1+nx_2}{m+n}, \frac{my_1+ny_2}{m+n})=(4,1)

But m:n=3:4 implies m=3 and n=4 and (x_2=12,y_2=5)

(\frac{3x_1+4*12}{3+4}, \frac{3y_1+4*5}{3+4})=(4,1)

(\frac{3x_1+48}{7}, \frac{3y_1+20}{7})=(4,1)

\frac{3x_1+48}{7}=4, \frac{3y_1+20}{7}=1

3x_1+48=28, 3y_1+20=7

3x_1=-20, 3y_1=-13

x_1=-\frac{20}{3} , y_1=-\frac{13}{3}

Pythagorean theorem, I'm trying to fix my grade for school so I get my phone back
Harrizon [31]

If you would illustrate the problem, you will be able to formulate a triangle with the measurement of the hypotenuse (distance between the two shops) to be missing. Using the Pythagorean Theorem, the formula to compute for the hypotenuse is:

c = √a^2 + b^2

c = √(20)^2 + (13.5)^2

c = √400 + 182.25

c = √582.25

c = 24.13 km

Therefore, the distance between the two shops is approximately 24.13 km.

Solve. 14/n+7=10/n-4<br><br> N=5.25<br> N=3.5<br> N=31.5<br> N=30
Ilya [14]

Answer:

n=31.5

Step-by-step explanation:

The given question is:

\frac{14}{n+7}=\frac{10}{n-4}

Cross multiply to get:

14(n-4)=10(n+7)

Expand the parenthesis:

14n-56=10n+70

Group similar terms:

14n-10n=70+56

Combine the like terms

4n=126

Divide both sides by 4

n=\frac{126}{4}

n=31.5

Triangle DEF is a right triangle and angles D and F are equal but are not right angles. What is the measure of angle E?
Andrej [43]
If it’s a right triangle 1 side is a right angle and if those 2 sides are equal and not right angles then E needs to be a right angle and a right angle is 90 degrees so it’s D
