10.

the various sides and line segments have been marked as equal already.

so, SSS proves that both triangles are congruent.

but to reprove things with the midpoint theorem :

remember

the line segment in a triangle connecting the midpoints of two sides of the triangle is said to be parallel to its third side and is also half of the length of the third side.

so,

D, F are the midpoints of BA and BC.

so, AC is parallel to DF and twice as long as DF.

D, E are the midpoints of BA and AC.

so, BC is parallel to DE and twice as long as DE.

E, F are the midpoints of AC and BC.

so, BA is parallel to EF and twice as long as EF.

so, DF = AE = EC

DE = BF = FC

EF = BD = DA

so, the EF of DEF corresponds to DA of ADE.

DF corresponds to AE.

and DE is shared between both triangles.

so, again, all 3 sides correspond 1:1 to sides in the other triangle. and SSS proves they are congruent.

11.

equilateral means all 3 sides are equal :

PS = PT = ST

TSR can only be isoceles (both legs are equal) when

ST = SR

because PM = MQ, M is the midpoint of PQ.

and because of MS || QR, S is the midpoint of PR.

that means PS = SR.

and because PS = ST, ST = SR

therefore, TSR is isoceles.

Total balance in the account after 7 months is 2849.737$

It is given that Timothy deposits $2780.20 in a savings account

It is given that rate of interest is 4.3 % and it of the simple interest nature.

We are required to find the account balance of Timothy's account in 7 months

We know that formula of simple interest is given by

(principal x rate x time)/100

where principal is the amount put for investing

rate is the rate at which the person is going to earn

time is the time for which the amount is to be invested

Now the time that is given to us in the form of months and hence we must convert it into years form

1 year =12 months

therefore, 7 months = 7/12 years

Now applying this value to calculate the simple interest earned

Let the simple interest be 'SI'

principal = $2780.20

rate = 4.3%

time = 7/12 years

SI= (2780.20x 4.3 x 7)/100 x 12

   = 69.737$

The balance in Timothy's account will be original amount + the simple interest

Total balance after 7 months = 2780.20+69.737

                                                  =2849.937$

Hence total balance in the account after 7 months is 2849.737$

The equation of the tangent line to the graph is equal to y = 0.

A line is tangent to a function if and only if the function meets the curve only in one point. The slope of the tangent line can be found by using the first derivative of the curve and the y-intercept is determined from the slope-intercept form of the equation of the line. First, determine the slope of the tangent line:

f'(x) = 12 · x

f'(0) = 12 · 0

f'(0) = 0

Second, find the intercept of the equation of the line:

y = 6 · 0²

y = 0

b = y - m · x

b = 0 - 0 · 0

b = 0

Then, the equation of the tangent line to the graph is equal to y = 0.

You want the factors of 12.

The prime factors of 12 are ...

  12 = 2·2·3 = 2²·3

The product of exponents of the prime factors, each increased by 1, is the number of divisors of 12:

  (2+1)(1+1) = 3·2 = 6 . . . . number of divisors of 12.

Those are ...

The word "factors" is often used when "divisors" is intended. An expression is factored when it is expressed as a product of prime factors.

If the vertices of the triangle are J(-3,-5), K(-2,2) and L(1,-4) then its reflection in y axis are J(3,-5), K(2,2) and L(-1,-4)

Given,

The vertices of the triangle = J(-3,-5), K(-2,2) and L(1,-4)

We know,

In reflection in y axis (x,y)  will become (-x,y)

Then the vertices of the reflection in y axis = J(3,-5), K(2,2) and L(-1,-4)

Draw the triangle using the vertices.

Hence, if the vertices of the triangle are J(-3,-5), K(-2,2) and L(1,-4) then its reflection in y axis are J(3,-5), K(2,2) and L(-1,-4)

From the given absolute value function, we have that:

The absolute function is defined by:

It measures the distance of a point x to the origin.

For this problem, the function is:

d(t) = 1/3|t - 60|.

The d-intercept is given by:

d(0) = 1/3|-60| = 20.

Hence: The cyclist starts 20 kilometers from the station.

The t-intercept is found as follows:

1/3|t - 60| = 0

t - 60 = 0

t = 60.

Step-by-step explanation:

First, split the figure into 3 rectangles and label the sides so that it is easier to work with.

Then you have to find the unknown values: HG and AH.

HG: Since AB=7 and AB is the longest horizontal side; we know that HG+EF+CD=AB=7. Plugging in the known values: HG+3+1=7 => HG+4=7. Therefore, HG=3 because 3+4=7.

AH: BC and FG are the corresponding sides to AH so AH+FG=BC. Plugging in the known values: AH+1=3. Therefore, AH is 2 because 2+1=3.

Now you have to use the perimeter of rectangle formula which is P=2(L+w) for the 3 rectangles.

Rectangle 1: 2(3+2)=10

Rectangle 2: 2(3+1)=8

Rectangle 3: 2(3+1)=8

Add them all up to find the total perimeter: 10+8+8=26.

If initial deposit is GBP 3000 and the rate is 3.5%,then after 32 years it will reach to GBP 9000.

Given that the initial deposit is GBP 3000 and the rate is 3.5%.

We are required to find the number of years after which the amount will reach to GBP 9000.

Compound interest is basically the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.

Amount after compounding=P[tex](1+r)^{n}[/tex], where P is principal ,r is rate of interest and n is number of years.

The number of years can be calculated as under:

9000=3000[tex](1+0.035)^{n}[/tex]

3=[tex](1.035)^{n}[/tex]

[tex](1.035)^{32}[/tex]=[tex](1.035)^{n}[/tex]

The standard deviation would be about the same, perhaps a little smaller.

The inequality that represents the temperatures at which the gas in the truck will remain in liquid form is;  -40°F < x < 140°F

A)  x is the temperature, and the temperature can't go down to -40°F and so x is greater than -40°F so that the gas doesn't freeze. Finally, x can't go higher than 140°F because the gas will evaporate. Thus, the inequality that represents the temperatures at which the gas in the truck will remain in liquid form is;

-40°F < x < 140°F

B) Open interval of the graph would mean that the interval is from -40°F to < 140°F. However, not equal to means that the gas in the truck can't stay liquid and as such means the coordinate is (-40°F, 140°F)

C) The gas will freeze because it has been said in the question the gas freezes at -40°F and as such if it goes -49°F, then it will freeze because the gas is supposed to stay higher than -40°F.

The equation for the average cost function C   [tex]= \frac{0.00048(x - 200)^{3} + 246840 }{x}[/tex]

When a company creates products or services, it is required to pay production-related expenses. Some of these expenses are cyclical and alter as the output does. Expenditures that alter when production changes include things like raw materials, labor, and utility costs. These are referred to as variables. Other expenses are set, such as rent and insurance payments. These fixed expenses do not alter with changes in output.

The sum of the fixed and variable costs is the total cost.

Total Cost = Variable Cost + Fixed Cost

Now as per the question the cost equation is :

[tex]= \frac{C(x)}{x} = \frac{0.00048(x - 200)^{3} + 246840}{x}[/tex]

The number of cars should be 100 and that of bus be 0.

x is the number of cars and y is the number of buses.

Area: 6x + 30y <= 600 simplifies to x + 5y <= 100

Total money collected: 2.50x + 7.50 y …..this is what you want to maximize

OR you want to maximize 2.50 (x+ 3 y)

OR you want to maximize (x+3y)

Replacing the value of x from the Area equation in the above price, we get

100 - 5y + 3y is the maximum amount you can collect

So you want to maximize 100 - 2y. This happens when y is 0.

When y is 0; x will be 100 and you will collect 250.
