Answer:

The key is to prove that the triangles are congruent, then their corresponding parts are congruent.

Step-by-step explanation:

#5)

It it given that:

Angle CBD is congruent to angle CDB.

Angle BAE is congruent to angle DEA.

Triangle CBD is isosceles because it's base angles are equal. Therefore, segment CB is congruent to segment CD.

Triangle CAE is isosceles because it's base angles are equal. Therefore, segment CA is congruent to segment CE.

CA-CB=BA

CE-CD=DE

segment BD is congruent to segment DB.

Angle ABD is supplementary to angle CBD (180-angle CBD= angle ABD).

Angle EDB is supplementary to angle CDB (1980-angle CDB=angle EDB).

therefore, angle ABD=angle EDB.

Triangles ABD and EDB are congruent because of the Side-angle-side theorem.

Triangles ABD and EDB are congruent, segment AD is congruent to segment EB because corresponding legs of congruent triangles are congruent.

#6)

It is given that:

Angle EBC is congruent to angle ECB

Segment AE is congruent to segment DE.

Triangle BEC is iscsceles because it's base angles are equal. Therefore, segment EB is congruent to segment EC.

AE+EC=AC

DE+EB=DB

segment BC is congruent to segment CB.

Triangle BAC is congruent to triangle CDB because of the side-angle-side theorem.

Segment AD is congruent to segment DC because corresponding legs of congruent triangles are congruent.

Answer:

Problem 5)

Step 1:  < CBD = <CDB Reason: given

Step 2: BC = CD  Reason: opposed sides in the isosceles triangle BCD

Step 3: < BAE = < DEA Reason: given

Step 4: AC = CE Reason: opposed sides in the isosceles triangle ACE

Step 5: triangle ACD  = triangle BCE Reason: angle <C is common, and equal sides shown above so use SAS theorem.

Step 6: AD =  BE Reason: third side in the equal triangles shown above.

Problem 6)

Step 1: < ECB = <EBC Reason: Given

Step 2> triangle BEC is isosceles Reason: has two equal angles

Step 3: BE = EC Reason: opposite sides in the isosceles triangle

Step 4: <DEC = < AED Reason: opposed by the vertex (vertical angles)

Step 5: AE = ED Reason: given

Step 6: triangle BAE = triangle EDC Reason SAS theorem

Step 7: side AB = side CD Reason: third side in the equal triangles

For 0<x<4, the average rate of change will be -60

For 4<x<8 the the average rate of change will be -31

And for the sentence (on savass in order is)

Stay negative, -31, decrease but at a slower rate

In this exercise we have to use the knowledge of functions to describe the average rates of each one of them, so:

For 0<x<4 will be -60

For 4<x<8 will be -31

First, we have to remember what an average rate means, like:

Answer:

$23.20

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 4%/100 = 0.04 per year,

then, solving our equation

I = 20 × 0.04 × 4 = 3.2

I = $ 3.20

The simple interest accumulated

on a principal of $ 20.00

at a rate of 4% per year

for 4 years is $ 3.20.

Based on the calculations, your balance after four (4) years is equal to $23.2.

Given the following data:

To determine the balance after four (4) years:

Mathematically, simple interest is given by this formula:

[tex]I = PRT[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]I=20 \times 0.04 \times 4[/tex]

Simple interest = $3.2.

Balance = [tex]3.2 +20[/tex] = $23.2.

Answer:

The equation of the circle is [tex](x + 1)^2 + y^2 = 25[/tex]

Step-by-step explanation:

Equation of a circle:

The equation of a circle of centre [tex](x_c,y_c)[/tex] has the following format:

[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]

In which r is the radius.

Center (-1,0)

This means that [tex]x_c = -1, y_c = 0[/tex]. So

[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]

[tex](x - (-1))^2 + (y - 0)^2 = r^2[/tex]

[tex](x + 1)^2 + y^2 = r^2[/tex]

Finding the radius:

Distance between the radius and the centre and a point of the circle. In this case, point (2,-4). Using the formula for the distance between two points:

[tex]r = \sqrt{(2-(-1))^2+(-4-0)^2} = \sqrt{3^2 + 4^2} = \sqrt{25} = 5[/tex]

So, the equation of the circle is:

[tex](x + 1)^2 + y^2 = 5^2[/tex]

[tex](x + 1)^2 + y^2 = 25[/tex]

Answer:

5(x+1)=2(x-2)

Answer:

x = -6 and x = 1

Step-by-step explanation:

Move everything to the left side of the equation by subtracting (-10x + 12)

2x² = -10x + 12

2x² + 10x - 12 = 0

Divide each side by 2:

x² + 5x - 6

Find 2 factors of -6 that add up to 5. These factors are 6 and -1

x² + 5x - 6

(x + 6)(x - 1)

Set this equal to 0 and solve for x

(x + 6)(x - 1)

x + 6 = 0

x = -6

x - 1 = 0

x = 1

So, the solutions to the equation are x = -6 and x = 1

The solutions to the equation 2x² = -10x + 12 are x = -6 and x = 1.

To find the solutions to the quadratic equation 2x² = -10x + 12, we can rearrange the equation into standard quadratic form, which is ax² + bx + c = 0.

First, we move all the terms to one side of the equation:

2x² + 10x - 12 = 0

Next, we can solve this equation by factoring, completing the square, or using the quadratic formula. In this case, we'll use factoring.

Looking at the equation, we notice that all coefficients are even, so we can simplify the equation by dividing both sides by 2:

x² + 5x - 6 = 0

Now, we factor the quadratic expression:

(x + 6)(x - 1) = 0

By setting each factor equal to zero, we can find the solutions:

x + 6 = 0 --> x = -6

x - 1 = 0 --> x = 1

Therefore, the solutions to the equation 2x² = -10x + 12 are x = -6 and x = 1. These values make the equation true when substituted back into the original equation.

the 2nd expression is the answer

Answer:

x = 5/2 km/h

Step-by-step explanation:

Lets x be the speed of the current

The sea lion's speed with the current: 15 + x

The sea lion's speed against the current: 15 - x

Total distance in km with the current: 35

Total distance in km against the current: 25

Time with the current: 35/(15 + x)

Time against the current: 25/(15 - x)

So we do...

35/(15 + x) - 25/(15 - x) = 0

35(15 - x)/(15 + x) - 25(15 + x)/(15 - x): Having common denominators which is (15 + x)(15 - x)

525 - 35x - 375 - 25x = 0: Mutipling the (15 + x)(15 - x)to 0 getting 0

150 - 60x = 0

30(5 - 2x) = 0

x = 5/2

The speed of the current is 2.5 km/hr

From the given information

Lets x be the speed of the current

Also, we have that;

Total distance in km with the current to be 35 while the total distance in km against the current is 25

mathematically;

Time with the current = 35/(15 + x)

Time against the current =  25/(15 - x)

Equating both expression to get the value of "x

35/(15 + x) = 25/(15 - x) = 0

35/(15 + x) - 25/(15 - x) = 0

35(15 - x)/(15 + x) - 25(15 + x)/(15 - x)

Mutiplying the (15 + x)(15 - x)to have:

150 - 60x = 0

30(5 - 2x) = 0

x = 5/2

x = 2.5

Hence the speed of the current is 2.5 km/hr
