Answer:
Step-by-step explanation:
Gabriela's mass : Pierre's mass = 3 : 8
Gabriela's mass = 3x
Pierre's mass = 8x
Total mass= (1/4) of total height
3x + 8x = [tex]\frac{1}{4}(110 + 154)[/tex]
11x = [tex]\frac{1}{4}*264[/tex]
11x = 66
x = 66/11
x = 6
Gabriela's mass = 3x = 3*6 = 18 Kg
Pierre's mass = 8x = 8*6 = 48 kg
Find an equation for the perpendicular bisector of the line segment whose end points are (-9,-8) and (3,-2)
Answer:
[tex]y=-2x-11[/tex]
Step-by-step explanation:
Slope of the line segment = [(-8)-(-2)]/[(-9)-3]=-6/-12=1/2
Slope of the perpendicular bisector x slope of line segment = -1
Slope of perpendicular bisector = -2
Mid-point of line segment = ((-9+3)/2, (-8+(-2))/2) = (-3, -5)
The perpendicular bisector passes through the mid-point.
By point-slope form,
[tex]\frac{y-(-5)}{x-(-3)} = -2\\y+5=-2x-6\\y=-2x-11[/tex]

Let Ln denote the left-endpoint sum using n subintervals and let Rn denote the corresponding right-endpoint sum. In the following exercise, compute the indicated left and right sums for the given function on the indicated interval.
L4 for f(x)=1/x−1; [2,3]
Answer:
[tex]L_4=0.7595[/tex]
Step-by-step explanation:
We are given that
[tex]f(x)=\frac{1}{x-1},[/tex][2,3]
We have to find L4
It means n=4
[tex]\Delta x=\frac{b-a}{n}=\frac{3-2}{4}=\frac{1}{4}=0.25[/tex]
Now, intervals are
[2,2.25],[2.25,2.50],[2.5,2.75],[2.75,3]
Now,
[tex]L_4=f(x_0)\Delta x+f(x_1)\Delta x+f(x_2)\Delta x+f(x_3)\Delta x[/tex]
[tex]L_4=\frac{1}{2-1}(0.25)+\frac{1}{2.25-1}(0.25)+\frac{1}{2.5-1}(0.25)+\frac{1}{2.75-1}(0.25)[/tex]
[tex]L_4=0.7595[/tex]

In the equation of a straight line, y = mx + c. what does the 'c' represents
Answer:
Equations of straight lines are in the form y = mx + c (m and c are numbers). m is the gradient of the line and c is the y-intercept (where the graph crosses the y-axis).
In the equation of a straight line, y = mx + c. what does the 'c' represents?
Equations of straight lines are in the form y = mx + c (m and c are numbers). "m" is the gradient of the line and "c" is the y-intercept (where the graph crosses the y-axis).

Ivan has 6 times as many blue beads as red beads. he has 49 red and blue beads in all. how many blue beads does Ivan have
Answer:
Ivan has 42 blue beads.
Step-by-step explanation:
We need to find how many blue beads Ivan has.
Blue beads = 6 times as many as red beans
b = 6r
r + b = 49
r + (6r) = 49
7r = 49
Divide both sides by seven to isolate r
r = 7
b = 6(7)
b = 42
