Answer/Step-by-step Explanation:

When calculating the length of a segment on a number line, the absolute value of the difference between one point on the numberline, and another point is what we're looking for.

1. Length of RS = |-5 - (-2)| = |-5 + 2| = |-3|

RS = 3

2. Length of RT = |-5 - 2| = |-7|

RS = 7

3. Length of ST = |-2 - 2| = |-4|

ST = 4

4. Length of RU = |-5 - 8| = |-13|

RU = 13

5. Given that the following coordinates:

P = 3

Q = 8

R = 14

5. PQ = |3 - 8| = |-5| = 5

6. QR = |8 - 14| = |-6| = 6

7. PR = |3 - 14| = |-11| = 11

Given that points A, B, C, and D are collinear, and AB = x, BC = 3x, CD = 4x - 13

8. If AC = 24,

BC can be calculated as follows:

AB + BC = AC

[tex] x + 3x = 24 [/tex]

Solve for x

[tex] 4x = 24 [/tex]

Divide both sides by 4

[tex] x = 6 [/tex]

Thus,, BC = 3x = 3(6) = 18

BC = 18

9. If BC = 15, BD can be calculated as follows:

Find the value of x first

BC = 3x

15 = 3x

Divide both sides by 3

5 = x

x = 5.

BD = [tex] 3x + (4x - 13) [/tex]

Plug in the value of x

BD = [tex] 3(5) + (4(5) - 13) = 15 + (20 - 13) [/tex]

BD = [tex] 15 + 7 = 22 [/tex]

BD = 22

10. m<PTR = 80° (taking the reading at the top from 0°)

11. m<PTQ = 45°

12. m<QTS = 128 - 45 = 83°

13. Luis read m<QTR wrongly, what he measured was the whole of <PTR.

According to the angle addition theorem, m<QTR = 80 - 45 = 35°.

Your question has been heard loud and clear.

2^0= 1

5^1= 5

4^3=64

2^0+5^1+4^3/7= 1+5+64/7 =  6+64/7= 15.14

So , 2^0+5^1+4^3/7 =  15.14

Thank you

Answer:

The slope becomes 0.5625 and y intercept becomes 12.5.

$65.9375

Step-by-step explanation:

Given that

the total reimbursement function in terms of [tex]m[/tex] miles:

[tex]f(x) = 0.45m +5[/tex]

After the policy change, 5 more dollars are added and then total amount is multiplied by 1.25.

To find:

How to transform the graph of f.

Total reimbursement for a trip of 95 miles?

Solution:

[tex]f(x) = 0.45m +5[/tex] can also be written as:

[tex]y = 0.45m +5[/tex]

It is nothing but slope intercept form, comparing with [tex]Y = M X+ C[/tex]

M is the slope and C is the y intercept.

Slope of the graph is 0.45.

Y intercept is 5.

After change in the function, first of all add $5.

[tex]0.45m + 5+5 = 0.45m+10[/tex]

Now, multiply with 1.25

Resulting function becomes:

[tex]f(x) =1.25\times (0.45m+10)\\\Rightarrow f(x) =0.5625m+12.5[/tex]

Kindly refer to the attached image for the graph of the two functions.

Now, the slope becomes 0.5625 and y intercept becomes 12.5. This is the transformation.

To find the reimbursement for a trip of 95 miles:

Put m = 95

[tex]f(95) =0.5625\times 95+12.5 = \bold{\$65.9375 }[/tex]

Answer:

504  

Step-by-step explanation:

I think the correct question is like:The common ratio in a geometric series is 0.50 ( point 5) and the first term is 256.  

Find the sum of the first 6 terms in the series.

If it's right, then

Sₙ = (a₁ × (1 - rⁿ)) / (1 - r)

S₆ = (256 × ( 1 - 0.5⁶)) / (1 - 0.5)

= (256 × 0.984375) / 0.5

= 504

Answer:

[tex]\frac{a}{b} = \frac{3}{10}[/tex]

Step-by-step explanation:

Given

[tex]Number = 0.3[/tex]

Required

Represent as [tex]\frac{a}{b}[/tex]

Let [tex]\frac{a}{b} = 0.3[/tex]

This can be further written as

[tex]\frac{a}{b} = \frac{0.3}{1}[/tex]

Multiply the numerator and denominator by 10

[tex]\frac{a}{b} = \frac{0.3 * 10}{1 * 10}[/tex]

[tex]\frac{a}{b} = \frac{3}{10}[/tex]

Since 3 and 10 are both integers, then

[tex]\frac{a}{b} = \frac{3}{10}[/tex]

Answer:

The solution is (3, -3)

Step-by-step explanation:

5x + 2y = 9

2x - 3y = 15

Use elimination by addition/subtraction.  Multiply the first equation by 3 and the second by 2, obtaining:

15x + 6y = 27

4x   - 6y  =  30

----------------------

19x        = 57

This yields x = 3.

Substituting 3 for x into 5x + 2y = 9, we get  5(3) + 2y = 9, or

15 + 2y = 9, or

2y = -6

This yields y = -3.

The solution is (3, -3)

Answer:

Slope= -4/3

Step-by-step explanation:

The points are (−3,−3) and (-9, 5)

Slope= gradient between the two points

Slope= (y2-y1)/(x2-x1)

Where y2= 5

Y1= -3

X2= -9

X1= -3

Slope= (y2-y1)/(x2-x1)

Slope= (5-(-3))/(-9-(-3))

Slope= (5+3)/(-9+3)

Slope= 8/-6

Slope= -4/3

Answer:

Complementary angles add up to 90 degrees, or a right angle.

In this case, it would be (c) AEF and FED, AEG and CEG

Step-by-step explanation:

(A)

[tex]\dfrac{\partial f}{\partial x}=-16x+2y[/tex]

[tex]\implies f(x,y)=-8x^2+2xy+g(y)[/tex]

[tex]\implies\dfrac{\partial f}{\partial y}=2x+\dfrac{\mathrm dg}{\mathrm dy}=2x+10y[/tex]

[tex]\implies\dfrac{\mathrm dg}{\mathrm dy}=10y[/tex]

[tex]\implies g(y)=5y^2+C[/tex]

[tex]\implies f(x,y)=\boxed{-8x^2+2xy+5y^2+C}[/tex]

(B)

[tex]\dfrac{\partial f}{\partial x}=-8y[/tex]

[tex]\implies f(x,y)=-8xy+g(y)[/tex]

[tex]\implies\dfrac{\partial f}{\partial y}=-8x+\dfrac{\mathrm dg}{\mathrm dy}=-7x[/tex]

[tex]\implies \dfrac{\mathrm dg}{\mathrm dy}=x[/tex]

But we assume [tex]g(y)[/tex] is a function of [tex]y[/tex] alone, so there is not potential function here.

(C)

[tex]\dfrac{\partial f}{\partial x}=-8\sin y[/tex]

[tex]\implies f(x,y)=-8x\sin y+g(x,y)[/tex]

[tex]\implies\dfrac{\partial f}{\partial y}=-8x\cos y+\dfrac{\mathrm dg}{\mathrm dy}=4y-8x\cos y[/tex]

[tex]\implies\dfrac{\mathrm dg}{\mathrm dy}=4y[/tex]

[tex]\implies g(y)=2y^2+C[/tex]

[tex]\implies f(x,y)=\boxed{-8x\sin y+2y^2+C}[/tex]

For (A) and (C), we have [tex]f(0,0)=0[/tex], which makes [tex]C=0[/tex] for both.

Answer:

Step-by-step explanation:

Ara of a triangle = 1/2 * base * height.

Before we find the area, we must look for all the sides of the triangle by taking the difference between any two points.

Given D = √(x₂-x₁)²+(y₂-y₁)²

Given the coordinates P(7,-3), Q(4,-3), R(4,9)

For the coordinates P(7,-3), Q(4,-3)

Given PQ = √(4-7)²+(-3+3)²

PQ = √(-3)²+0

PQ =  √9

PQ = 3

For coordinates P(7,-3), R(4,9)

Given PR = √(4-7)²+(9+3)²

PR = √(-3)²+12²

PR =  √9+144

PR = √153

For coordinates Q(4,-3), R(4,9)

Given QR = √(4-4)²+(9+3)²

QR = √(0)²+12²

QR =  √0+144

QR = 12

Since it is a rright angled triangle, the base of the triamgle will be QR and the height will be PQ since the longest side is PR

Area of the triangle = 1/2 * PQ*QR

Area of the triangle = 1/2 * 12*6

Area of the triangle = 6*6

Area of the triangle = 36 square units

Step-by-step explanation:

Given,

Area of rectangular piece of land ( l ) = 220 m²

Width ( w ) = 12.5 m

Finding length of the rectangular piece of land

[tex] \boxed{ \sf{area \: of \: rectangle = l \times w}}[/tex]

plug the values

⇒[tex] \sf{220 = l \times 12.5}[/tex]

Swap the sides of the equation

⇒[tex] \sf{12.5 \: l = 220}[/tex]

Divide both sides of the equation by 12.5

⇒[tex] \sf{ \frac{12.5 \: l}{12.5} = \frac{220}{12.5} }[/tex]

Calculate

⇒[tex] \sf{l = 17.6 \: m}[/tex]

Length of rectangular piece of land ( l )= 17.6 m

Finding perimeter of rectangular piece of land

[tex] \boxed{ \sf{perimeter \: of \: rectangle = 2(l + b)}}[/tex]

plug the values of length and breadth

⇒[tex] \sf{2(17.6 + 12.5) }[/tex]

Add the numbers

⇒[tex] \sf{2 \times 30.1}[/tex]

Multiply the numbers

⇒[tex] \sf{60.2 \: m}[/tex]

Therefore, Perimeter of rectangular piece of land is 60.2 m

Answer:

we accept the alternate hypothesis that

there is a difference between the rate of medical malpractice lawsuits that go to trial and the rate of such lawsuits that are dropped or dismissed.

Step-by-step explanation:

We first write out our null and alternate hypothesis.

H0: no difference

H1: there is difference

n = 1228

P = 856

X = n-p

= 372

Z = ((x+0.5)-1228/2) divided by √1228/2

= 372.5 - 614/17.52

= -13.784

|Z|= 13.784

The decision is to reject the null hypothesis and accept the alternate because there is evidence that dismissed lawsuit if bigger than 0.5. so there is difference between lawsuits that go to trial and lawsuits that are dismissed

3 + 1 = K

K = 4

To obtain sample size (N) :

Degree of freedom of Error (DFE) is the difference between the sample size and the number of groups observed.

DFE = N - K ; From. The table DFE = 102 ; K = 4

102 = N - 4

102 + 4 = N

N = 106

Answer:

The standard deviation is  [tex]\sigma = 1.17[/tex]      

Step-by-step explanation:

From the question we are told that

   The data is  

 x          1  2  3        4

P(X = x)    0.2 0.2 0.2   0.4  

 Generally the standard deviation is mathematically represented as

           [tex]\sigma = \sqrt{ \sum x^2 P(x) - (\sum x P(x))^2 }[/tex]

Here    [tex]x^2 = 1^2 \ \ 2^2 \ \ 3 ^2 \ \ 4^2[/tex]

    =>     [tex]x^2 = 1 \ \ 4 \ \ 9\ 16 \[/tex]

      [tex]\sum x^2 * P(x) = (1 * 0.2) + (4 * 0.2 ) + (9 * 0.2 ) + (16 * 0.2 )[/tex]

     [tex]\sum x^2 * P(x) = 9.4[/tex]

      [tex]\sum x P(x) = (1 *0.2) + (2*0.2) + (3 * 0.2) + (4 * 0.2)[/tex]

     [tex]\sum x P(x) = 2.8[/tex]
