Given:
Endpoints of a line segment EF are E(-3,8) and F(7,-7).
Point P divides the segment EF such that EP:PF = 2:3.
To find:
The coordinates of the point P.
Solution:
Section formula: If a point divides a line segment in m:n, then the coordinates of the points are:
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
It is given that EP:PF = 2:3. It means the point P divides the segment EF in 2:3.
Using section formula, we get
[tex]P=\left(\dfrac{2(7)+3(-3)}{2+3},\dfrac{2(-7)+3(8)}{2+3}\right)[/tex]
[tex]P=\left(\dfrac{14-9}{5},\dfrac{-14+24}{5}\right)[/tex]
[tex]P=\left(\dfrac{5}{5},\dfrac{10}{5}\right)[/tex]
[tex]P=\left(1,2\right)[/tex]
Therefore, the coordinates of the point P are (1,2).
You 5-year loan of $14,000 is at 4.3% compounded annually. How much will you have paid in total for your loan?
Answer:
$17,276
Step-by-step explanation:
Given data
Time= 5 years
Principal= $14,000
Rate= 4.3%
We want to find the final amount
A=P(1+r)^t
Substitute
A= 14000(1+0.043)^5
A= 14000(1.043)^5
A= 14000*1.234
A=$17276
Hence the total amount is $17,276

select all of the following that could be cross-sections of the cone shown below
circle
oval
parabola
rectangle
trapezoid
triangle
Answer:
oval, triangle
hope it helped you ☺
The cross sections of the cone shown can be circle, oval, parabola and triangle.
What is Cross Section?Cross section of a figure or shape can be defined as a plane intersecting with the figure. The resulting shape formed in the intersection part is termed as cross section.
Given shape is a cone.
When a cone is intersected vertically, then the cross section formed is triangle.
When the cone is intersected through the straight horizontal line, we get the cross section as circle.
We will get an oval shape when the cone is intersected with the plane with a given slant by not touching the base.
A parabola shape is formed when a slant plane intersects by touching the base
Hence the cross sections of the given cone are circle, oval, parabola and triangle.

the error in solving the inequality.
x/3 + 4 < 6
x + 4 < 18
x < 14
Answer: The correct answer should be x < 6
Step-by-step explanation:
When you multiplied both sides of the inequality by 3 to get rid of the /3, you didn't multiply 4 by 3.

I need so much help ☹️
Answer:
666mm
Step-by-step explanation:
A= 1/2 Base x Height . For triangle
A= 1/2 (10)(12)
A=1/2 (120)
A=60 . One triangle is 60, so 2 triangles are 120 mm
Rectangle
A= BxH
A=(14)(13)
A=182mm But since there are 3 triangles you multiply 182 times 3
(182x3)+120
=666
Area of the figure is 666mm
If y varies directly with x, and y =9 when x=3, what is x when y=15
directly varies for that mean if y increases x will increase too and the other way around if y decreases x will decrease too.
an easy way to solve this is to make all values into fraction ik it sounds confusing lemme explain it. so if we say [tex]\frac{x}{y}[/tex] and add the values of the known [tex]\frac{3}{9}[/tex] we can say that if [tex]\frac{x}{15}[/tex] is equal to [tex]\frac{3}{9}[/tex]
now we just solve it for x
[tex]\frac{x}{15} = \frac{3}{9} \\9x = 45\\x= 5[/tex]
hence when y is 15 x will be 5
