Answer:
1 and 2.
Midpoints calculated, plotted and connected to make the triangle DEF, see the attached.
D= (-2, 2), E = (-1, -2), F = (-4, -1)3.
As per definition, midsegment is parallel to a side.
Parallel lines have same slope.
Find slopes of FD and CB and compare.
m(FD) = (2 - (-1))/(-2 -(-4)) = 3/2m(CB) = (1 - (-5))/(1 - (-3)) = 6/4 = 3/2As we see the slopes are sameFind the slopes of FE and AB and compare.
m(FE) = (-2 - (- 1))/(-1 - (-4)) = -1/3m(AB) = (1 - 3)/(1 - (-5)) = -2/6 = -1/3Slopes are sameFind the slopes of DE and AC and compare.
m(DE) = (-2 - 2)/(-1 - (-2)) = -4/1 = -4m(AC) = (-5 - 3)/(-3 - (-5)) = -8/2 = -4Slopes are same4.
As per definition, midsegment is half the parallel side.
We'll show that FD = 1/2CB
FD = [tex]\sqrt{(2+1)^2+(-2+4)^2}[/tex] = [tex]\sqrt{3^2+2^2}[/tex] = [tex]\sqrt{13}[/tex]CB = [tex]\sqrt{(1 + 5)^2+(1+3)^2}[/tex] = [tex]\sqrt{6^2+4^2}[/tex] = 2[tex]\sqrt{13}[/tex]As we see FD = 1/2CBFE = 1/2AB
FE = [tex]\sqrt{(-4+1)^2+(-1+2)^2}[/tex] = [tex]\sqrt{3^2+1^2}[/tex] = [tex]\sqrt{10}[/tex]AB = [tex]\sqrt{(-5 -1)^2+(3-1)^2}[/tex] = [tex]\sqrt{6^2+2^2}[/tex] = 2[tex]\sqrt{10}[/tex]As we see FE = 1/2ABDE = 1/2AC
DE = [tex]\sqrt{(-2+1)^2+(2+2)^2}[/tex] = [tex]\sqrt{1^2+4^2}[/tex] = [tex]\sqrt{17}[/tex]AC = [tex]\sqrt{(-5 +3)^2+(3+5)^2}[/tex] = [tex]\sqrt{2^2+8^2}[/tex] = 2[tex]\sqrt{17}[/tex]As we see DE = 1/2ACThere are 12 girls and 3 boys in the french club.

Answer:
Step-by-step explanation:
4 year Public University
Tuition and fees $ 8500
Room and board $ 6700
Books and supplies $1250
misc expenses $ 700
Total for 1 year
8500+6700+1250+700
= $ 17150
Total for 4 years 4* 17150 = $68600
4 year Private University
Tuition and fees $ 25100
Room and board $ 8000
Books and supplies $ 1300
misc expenses $ 750
Total for 1 year
25100+8000+1300+750
= $ 35150
Total for 4 years 4* 35150 = $ 140600
2 Year Community College
2 Year Community College
Tuition and fees $ 4400
Room and board $ 5000
Books and supplies $ 1100
misc expenses $ 800
Total for 1 year
4400+5000+1100+800
= $ 11300
Total for 2 years 2* 11300 = $ 22600
now given
kari will get $4500 in scholarships and grants yearly and $1500 yearly through work study program
so in total kari will get in financial aid = $6000 yearly
so in 2 years she will get total = 2*6000 = $12000 financial aid
kari's estimated cost per year = total fee of college for 1 year - total financial aid for 1 year
= $11300 - $ 6000 = $5300
Kari's estimated cost per year = $5300
then estimated cost for two years = 2* 5300 = $10600
given Kari's family will contribute $3000 yearly
so for two years Kari will get = 2*3000 = $6000 from family
If kari has 1 year to save for 1st year's contribution then
a) kari has $0 in savings
kari needs to save for year = estimated cos per year - contribution from family per year
= $5300 - $ 3000 = $2300
as kari has $0 savings so kari needs to save $2300 in 1 year
so kari needs to save an amount = 2300/12 = $191.666667 monthly
b) kari has $1000 in saving
then kari needs to save an amount for 1 year = estimated cost per year - contribution from family per year - kari's initial savings
Amount to be saved for 1 year = $5300 - $3000 - $1000
= $1300
so kari needs to save an amount of = 1300/12 = $108.3333333 monthly
c) Kari has $2000 in saving
then kari needs to save an amount for 1 year = estimated cost per year - contribution from family per year - kari's initial savings
Amount to be saved for 1 year = $5300 - $3000 - $2000
= $300
so kari needs to save an amount of = 300/12 = $25 monthly

On a snowy winters eve two candles are lit at the exact same time. A 18-inch candle and a 21-inch candle are lit at the exact same time. The 18-inch candle burns 2 inches every hour. The 21-inch candle burns 3 inches every hour. Create a system of equations using the information
Answer:
y=21-3x and y=18-2x
Step-by-step explanation:
Ok, so we have candle A, which is 21 inches and burns 3 inches every hour. in slope-intercept form, the hours would be the x, the 21 is our y intercept. So the first equatio would be y=-3x+21 (negative slope, because the height of the candle is going down). Candle b, which is 18 inches, burns away 2 inches each hour. We can make -2 the slope (negative 2, since the candle is being burned away, not being added to), and the 18 our y intercept. So the two equations would be
y=21-3x
and
y=18-2x
hope this helps!

1. A slice is being made to a cube. For each slice—
• Describe the two-dimensional figure resulting from the described slice. Use the specific name when possible.
• Determine whether a different slice can produce a congruent two-dimensional figure. If so, describe or sketch an example of the slice. If not, explain why not.
(a) a slice parallel to the base
(b) a slice that contains and
(c) a slice that contains and vertex F
(a.) A slice parallel to the base would result in two rectangular prisms, as opposed to a cube now. These two rectangular prisms would be congruent to each other as it is a perfect slice through the middle.
(b) A slice that contains and AE and DH will make a slanted cube, meaning it will turn into a cubic pyramid.
(c.) A slice that will contain and vertex F will make the cut the figure in half going slanted. They will technically be congruent, although there is no name for this figure.
2a.) A(t) is the average high temperature in Aspen, Colorado, "t" months after the
start of the year. M(t) is the average high temperature in Minneapolis, Minnesota,
"t" months after the start of the year. Temperature is measured in degrees
Fahrenheit. Which function had the HIGHER average rate of change between the
beginning of January and middle of March? *
Answer:
As you didn't add the graph, I will for you.
Step-by-step explanation:
The correct answer is Minneapolis because as you can see Aspen did not change as dramatically as Minneapolis.
The start of January and the middle of March, Minneapolis, or function M(t), had a larger average rate of change. It means that Minneapolis experiences a greater increase in temperature than Aspen does.
What is meant by function?A mathematical formula, rule, or legislation that establishes the link between the independent variable and the dependent variable (the dependent variable). In mathematics and the sciences, functions are fundamental for constructing physical relationships.
In the beginning of January, Aspen's temperature was 35° F, and in the middle of March, it was 48° F. 3.5 months later Minneapolis has lows of 25 degrees Fahrenheit in January and highs of 50 degrees Fahrenheit in the middle of March (at 3.5 months).
So, the average rate of change of temperature of Aspen between the points (1, 35) and (3.5, 48) exists
[tex]$\frac{y_2-y 1}{x_2-x_1}=\frac{48-35}{3.5-1}=5.2$[/tex]
The average rate of change of temperature of Minneapolis between the points (1, 25) and (3.5, 50) is [tex]$\frac{50-25}{3.5-1}=10$[/tex]
Thus, from the start of January and the middle of March, Minneapolis, or function M(t), had a larger average rate of change. It means that Minneapolis experiences a greater increase in temperature than Aspen does.

The coordinates of the point which lies on the equation is A ( 3 , -4 )
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
y + 4 = 4 ( x - 3 ) be equation (1)
when x = 3 and and y = -4
Substituting the values of x and y in the equation , we get
-4 + 4 = 4 ( 3 - 3 )
0 = 4 ( 0 )
0 = 0
Therefore , the point A ( 3 , -4 ) lies in the equation
