By SSS (Side, side, side) congruency;

⇒ Δ T J D ≅ ΔS E K

Given that;

The vertices of ΔT J D  are;

T (-4, -2) , J (0, 5),  and D (1, -1),

The vertices of  ΔS E K  are;

S (-1, 3), E (3, 10) , and K (4, 4)

We have to prove that  Δ T J D ≅ΔS E K.

What is congruency in triangle?

If all three corresponding sides are equal and all the three corresponding angles are equal in measure, then Two triangles are said to be congruent.

Now,

The vertices of ΔT J D  are;

T (-4, -2) , J (0, 5),  and D (1, -1),

The vertices of  ΔS E K  are;

S (-1, 3), E (3, 10) , and K (4, 4)

To prove Δ T J D ≅ΔS E K we use distance formula and prove all sides are equal.

In ΔT J D;

Distance between T and J;

[tex]D_{TJ} = \sqrt{(0-(-4))^2 + (5 -(-2))^2} = \sqrt{65}[/tex]

Distance between J and D;

[tex]D_{JD} = \sqrt{(1-0)^2 + (-1 -5)^2} = \sqrt{37}[/tex]

Distance between D and T;

[tex]D_{DT} = \sqrt{(1-(-4))^2 + (-1 -(-2))^2} = \sqrt{26}[/tex]

In ΔS E K;

Distance between S and E;

[tex]D_{SE} = \sqrt{(3-(-1))^2 + (10-3)^2} = \sqrt{65}[/tex]

Distance between E and K;

[tex]D_{EK} = \sqrt{(4-3)^2 + (4 -10)^2} = \sqrt{37}[/tex]

Distance between K and S;

Clearly, Distance between sides of  Δ T J D and ΔS E K are equal as;

[tex]D_{SE} = D_{TJ} \\\\D_{EK} = D_{JD}\\\\D_{KS} = D_{DT}[/tex]

Hence, By SSS congruency;

⇒ Δ T J D ≅ ΔS E K

The acceleration when he gets to the top is -0.0325 m/s²

From the question, we are to determine the acceleration when Jacob gets to the top

Using one of the equations of motion, we have that

v = u + at

Where v is the final velocity

u is the initial velocity

a is the acceleration

and t is the time

From the given information,

u = 15 mph = 6.7 m/s

v = 3 mph = 1.34 m/s

t = 2.75 minutes = 165 seconds

Then,

1.34 = 6.7 + a×165

1.34 - 6.7 = 165a

-5.36 = 165a

a = -5.36/165

a = -0.0325 m/s²

NOTE: Negative sign indicates deceleration

Hence, the acceleration when he gets to the top is -0.0325 m/s².

The system of equations, -x + y = -2 and 2x - 2y = 0, has no solution.

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

Given two equations in x and y,

-x + y = -2     (equation 1)

2x - 2y = 0     (equation 2)

Rewrite equation 1 as an equation of y and substitute to equation 2.

(equation 1) -x + y = -2     ⇒     y = x - 2

2x - 2y = 0     (equation 2)

2x - 2(x - 2) = 0

2x - 2x + 4 = 0

4 = 0

Since we do not have a definite value for x, and neither will be for y, the system of equation has no solution.

Checking the slope,

(equation 1) -x + y = -2     ⇒     y = x - 2

m = 1

(equation 2) 2x - 2y = 0     ⇒     y = x

m = 1

Since the two equations has the same slopes but different y-intercepts, then these two equations must be parallel with each other.

Answer: 7

Step-by-step explanation: You can find the mean, or average, of a data set in two simple steps: Find the sum of the values by adding them all up. Divide the sum by the number of values in the data set.

The speed written in standard form is 0.000008056  miles per second.

Here we know that the average speed of a garden snail is:

8.056 x 10⁻⁶ miles per second.

Notice that it is written in scientific notation and we want to write this in standard form, so we just need to expand the product.

Notice that the exponent is -6, this means that we need to "move" the decimal point 6 times to the left, so we will get:

S = 8.056 x 10⁻⁶ miles per second.

S = 0.000008056  miles per second.

That is the speed written in standard form.

The range of the quadratic function represented with the given parameters is {y | −7 < y ≤ 2}

The range of a function is the set of output values of the graph. This in other words mean the range of a function is the set of y values of the graph.

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

From the question, we have the following parameters:

Write out the vertex

So, we have

Vertex = (0, 2)

Remove the x value

y = 2

From the question, we have

The parabola opens downward

This means that the vertex is a maximum

So, the range is

Measure of angle 3 i.e. m∠3 = 130°

The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.

As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.

In the question,

Let given angle is ∠8.

Given, ∠8 = 50°

Now, according to supplementary angle property

∠8 + ∠6 = 180

50° + ∠6 = 180

∠6 = 130°

As, ∠6 and ∠2 are corresponding angles,

therefore, ∠6 = ∠2 = 130°

Also, ∠2 and ∠3 are vertical opposite angles,

thus, ∠2 = ∠3 = 130°

therefore, ∠3 = 130°

The sum of finite arithmetic series 1+4+7+ . . . . . .+31 is S(11) = 176

The given  arithmetic series is:

      1+4+7+ . . . . . .+31

From the above series, we know that:

The first term, a(1) = 1

The last term, a(n) = 31

The common difference, d = 4 - 1 = 3

Recall the formula to find the nth term of an arithmetic sequence:

a(n) = a(1) + (n-1) . d

Substitute a(1) = 1, a(n) = 31, and d = 3:

31 = 1 + (n-1) . 3

31 = 3n - 2

3n = 33

n = 11

In an arithmetic series, the sum of the first n terms is given by:

S(n) = n/2 [ a(1) + a(n) ]

Substitute n = 11, a(1) = 1, and a(n) = 31:

S(n) = 11/2 (1 + 31)

The function g(x)  whose graph is the horizontal shrink of the given graph of  f(x) =5x-6 by a factor (horizontal shrink factor) of 1/4 is  g(x)=5/4 x-6.

As per the question statement, we are supposed to find a function g(x) whose graph is a horizontal shrink of the given graph of f(x) =5x-6 by a factor of 1/4.

Before solving it lets assume f(x)=y

so y =5x-6

Comparing with y= mx+c  where m is the slope

so in y =5x-6  slope is m=5

For applying horizontal shrink by a factor of 1/4 we need to multiply the slope by a factor of 1/4

so new slope [tex]m_{1} =5*\frac{1}{4} =\frac{5}{4}[/tex]

Therefore [tex]g(x) = \frac{5}{4} x -6[/tex]
