Answer:

3. ASA (Angle Side Angle)

4. CPCTC (Congruent Parts of Congruent Triangles are Congruent)

Step-by-step explanation:

Since angle Q is congruent to angle T, side QR is congruent to side TR, and angle R is congruent to angle R, we can say that the triangles are congruent because of the Angle Side Angle Postulate.

With that being said, the other parts of the triangle are congruent, which is proved by the CPCTC theorem.

Complete question is;

A long steel beam has a length of twenty-five meters on a coldday when the temperature is 0°C. What is the length of the beam on a hot day when T = 40°C. (α_steel = 1.1 × 10^(-5) °/C)

a. 25.00044 m

b. 25.0044 m

c. 25.011 m

d. 25.044m

e. 25.11 m

Answer:

Option C: 25.011 m

Step-by-step explanation:

We are given;

Initial Temperature; T1 = 0°C

Final Temperature; T2 = 40°C

Coefficient of linear expansion of steel; α_steel = 1.1 × 10^(-5) °/C

Initial length; L_o = 25 m

We know that formula for change in length is;

ΔL = LαΔT

Plugging in the relevant values, we have;

ΔL = 25 × 1.1 × 10^(-5) × (40 - 0)

ΔL = 0.011 m

Thus, new length is;

L1 = L_o + ΔL

L1 = 25 + 0.011

L1 = 25.011

Answer:

a)[tex]R(x)=-520x^2+2600x[/tex]

b)[tex]P(x)=-520x^2+2600x-30[/tex]

c)x=2.5

d)P(x)=3220

Step-by-step explanation:

Let Demand function be  D=Ax+B

We are given that  When you charged $4 the demand was 520 log-ons per month

So, D = 520 , x = 4

So, 520=4A+B  ----1

We are also given that When you lowered the price to $3.50, the demand increased to 780 log-ons per month.

So, D=780 , x = 3.50

So, 780=3.5A+B ----2

Substract 2 form 1

4A+B-3.5A-B=520-780

0.5A=-260

[tex]A=\frac{-260}{0.5}[/tex]

A=-520

Substitute value of A in 2

780=3.5(-520)+B

780-3.5(-520)=B

2600=B

So, D=-520x+2600

Revenue = Demand (x)=(-520x+2600)(x)

a) [tex]R(x)=-520x^2+2600x[/tex]

b) Profit = Revenue - cost

[tex]P(x)=-520x^2+2600x-30[/tex]

c)to obtain the largest possible monthly profit.

Equate the first derivative of profit to 0

P'(x)=-1040x+2600=0

[tex]x=\frac{2600}{1040}[/tex]

x=2.5

d)Now to find  the largest possible monthly profit

Substitute x = 2.5 in Profit function

[tex]P(x)=-520(2.5)^2+2600(2.5)-30[/tex]

P(x)=3220

Answer:

a ) π/2, 4π/3, 3π/2. 5π/3.

Step-by-step explanation:

2 sin t cos t + √3 cos t = 0

cos t ( 2 sin t + √3 ) = 0

Therefore:

cos t = 0,   t 1 = π/2,  t 2 = 3 π/2

or:

2 sin t + √3 = 0

2 sin t = - √3

sin t = - √3 / 2

t 3 = 4 π/3,  t 4 = 5 π/3

Answer:

3X=54°

3X=54°

4X=72°

Step-by-step explanation:

3X+3X+4X=180°(SUM OF INTERIOR ANGLES OF A TRIANGLE ADOPTS TO      180°)

10X=180°

  X=18°

THERFORE;

       3X=18 * 3 = 54°

       4X=18 * 4 = 72°

The sum of all the interior angles of a triangle is 180°. The measure of the angles are 54°, 54° and 72°.

A triangle is geometric figure bounded by three straight lines.

The sum of all the interior angles of a triangle is 180°.

In a triangle, the length of the longest side is always less than the sum of the length of the other two sides.

In the given figure, the angles of a triangle are 3x, 3x and 4x.

Since the sum of interior angles is 180°,

3x + 3x + 4x = 180

x = 18

Thus the angles can be obtained by substituting the value of x as follows,

3x = 3 × 18 = 54°

3x = 3 × 18 = 54°

And, 4x = 4 × 18 = 72°.

Hence, the angles of the given triangle are  54°, 54° and 72°.

Answer:

  irrational

Step-by-step explanation:

A number that can be written as the ratio of two integers is called a "rational" number. If it cannot be written that way, it is called an "irrational" number

Irrational numbers cannot be written as a fraction of p/q.

Rational numbers can be written as a fraction of p/q.

1. The y-intercept of a line is on a graph where a line crosses through the y axis.

2. b is the y- intercept and m is the slope. For example something using y=mx+b could be written like y=3x+2 if the y-intercept is 2 and the slope is 3.

3. The slope is what describes the direction and steepness of a line on a graph. Rise and run mean that when you find a slope you must first find the rise over run. You must go from one dot on a graph to the next by first going up or down to where that you are on the same number on the y axis that the next point is, next go on the x axis and go left or right until you have reached the next point. For example if you went up 3 and over 2, the rise would be 3 and the run would be 2. The slope in that situation would be 3/2.

Hope this helps you.

Do the steps below on the graphing calculator:

✔ The line gets steeper.

Find the values of m and b that cause the graph to pass through the two points plotted.

m = ✔ 0.5

b = ✔ 5

11 + 5.75h = 19 + 4.5h

-11 from both sides

5.75h = 8 + 4.5h

-4.5h from both sides

1.25h = 8
