Choose all answers that apply: Choice A Quadrant I (Choice B) Quadrant II (Choice C) Quadrant III (Choice D) Quadrant IV (Choice E) x-axis (Choice F) y-axis

Answers

Answer:

Quadrant III ( C )

Step-by-step explanation:

Ordered pair ( a, b )

gives a point P on the coordinate plane

( a, b ) = ( x, y )

given : b = negative ( y-axis )

           a ≠ 0 ( i.e. a = negative or positive ) ( x -axis )

Therefore point P is located in the : Third and fourth quadrants

A student earned grades of 78, 72, 74, and 88 on her four regular tests. She earned a grade of 79 on the final exam and 88 on her class projects. Her combined homework grade was 89. The four regular
tests count for 40% of the final grade, the final exam counts for 20%, the project counts for 10%, and homework counts for 30% What is her weighted mean grade? Round to one decimal place.
O A. 82.5
OB. 71.0
O C. 63.6
OD. 81.5

Answers

Answer:

A: 82.5

Step-by-step explanation:

Average score of the 4 regular tests = (78 + 72 + 74 + 88)/4 = 78

We are told;

- the regular tests account for 40% of the final grade.

- final exam counts for 20%

- project counts for 10%

- homework counts for 30%

Thus;

weighted mean grade = (40% × 78) + (20% × 79) + (10% × 88) + (30% × 89) = 82.5

2∠15°2cos(15°) +i·2sin(15°) ≈ 1.93185 +0.517638i

Step-by-step explanation:

Using Euler's formula, the 6th root is easily found.

  (64i)^(1/6) = ((2^6)e^(iπ/2))^(1/6) = 2e^(iπ/12) = 2∠15°

  = 2(cos(15°) +i·sin(15°)) = 2·cos(15°) +i·2·sin(15°) ≈ 1.93185 +0.517638i

Find the linear equation whose graph is the straight line with the given properties through ( 1,-8) and (-1,-1)

Answers

Answer: y=-7/2x-9/2

Explanation: solving for y=mx+b (linear equation)

m(slope)=y2-y1/x2-x1
(x1= 1, y1=-8),(x2=-1,y2=-1)
M=-1-(-8)/-1-1=7/-2= -7/2

To find the b(y-intercept),use one of the coordinates and plug it into y=mx+b, I will use (x=1,y=-8): -8=-7/2(1)+b

-8/1=-7/2(1)+b/1 -divide the 1 to cancel it and bring it to the other side.

-8+7/2=-7/2+7/2+b -add the 7/2 to cancel it and bring it to the other side.

-9/2=b -b is now isolated and is solved.

So, that’s how you get y=-7/2x-9/2

The equation of a line for the given coordinates is 7x+2y+9=0.

The given coordinates are (1, -8) and (-1, -1).

We need to find the linear equation whose graph is a straight line.

What is the slope of a line?

The slope of a line is defined as the change in the y coordinate with respect to the change in the x coordinate of that line. The slope of a line=m=(y2-y1)/(x2-x1).

Now, slope of the line=(-1-(-8))/(-1-2)

=7/(-2)

=-7/2

Now, put m=-7/2 and (-1, -1) in the equation y=mx+c.

So, -1=(-7/2)(-1)+c

⇒-1-7/2=c

⇒c=-9/2

Then the equation of the line=y=-7x/2-9/2

⇒2y=-7x-9

⇒7x+2y+9=0

Therefore, the equation of a line for the given coordinates is 7x+2y+9=0.

For the right triangles below, find the values of the side lengths d and a.
Round your answers to the nearest tenth.

Answers

Answer:

a = 1.4 and d = 6.9

Step-by-step explanation:

To get the value of d and a, we will use the SOH CAH TOA identity

For the first tringle;

Opposite = d ((opposite angle 60 degrees)

Adjacent = 4

Tan theta = opp/adj

Tan 60 = d/4

d  = 4tan60

d = 4(1.732)

d = 6.9

For the second triangle;

Opposite = a

Hypotenuse = 2

Since sin theta = opp/hyp

Sin45 = a/2

a = 2sin45

a = 2(0.7071)

a = 1.4

Hence a = 1.4 and d = 6.9

A consultant for a major computer company receives $3250 per month as a fee no matter how many hours he works. Using x to represent the number of hours the consultant works each month, write a function, f, in symbolic form to represent the total amount the consultant recieves each month.

Answers

Answer:

The function is;

f(x) = $3,250

Step-by-step explanation:

The fixed amount the consultant receives each month = $3,250

The number of hours the consultant works each month = x

Let f(x) represent the function of the total amount the consultant receives each month

Therefore;

The function f(x) = The total amount the consultant receives each month = The fixed amount the consultant receives = $3,250

∴ f(x) = $3,250.

The function 'f' which represents the total amount the consultant receives each month is f(x) = $3,250 (Given that the consultant receives a constant amount each month).

The single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]

Logarithm and indices

Given the logarithmic expression;

[tex]2(log_38+log_3z)-log_3(3^4-7^2)[/tex]

We are to write it as a single logarithm

Using the product and quotient law of logarithm;

[tex]2(log_38+log_3z)-log_3(3^4-7^2)\\=2(log_38+log_3z)-log_3(\frac{81}{49} )\\=2(log_38z)-log(\frac{81}{9})\\=log_364z^2-log(\frac{81}{9})[/tex]

Simplify the final result to have:

[tex]=log_364z^2-log(\frac{81}{9})\\=log_3(\frac{9(64z^2)}{81} )[/tex]

Hence the single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]

Answer:

Part A

The required inequality is;

y = 50 - 2 × x  ≥ 20

Please find attached the graph of the inequality created with Microsoft Excel

Part B

The number of weeks she can withdraw is less than or equal to 15 weeks

Step-by-step explanation:

The given parameters are;

The amount Kate has in her savings account at the beginning of the summer = $50

The least amount she wants to have in the account at the end of the summer = $20

The amount she withdraws each weak from the account = $2

Part A

Let 'x' represent the number of weeks she can withdraw money, we have;

The required inequality that gives the number of weeks she can withdraw money is given as follows

y = 50 - 2 × x

y ≥ 20

Therefore, the inequality is;

y = 50 - 2 × x  ≥ 20

The graph of the inequality created with Microsoft Excel is attached

Part B

The number of 'x' weeks she can withdraw is;

50 - 2 × x  ≥ 20

- 2 × x  ≥ 20 - 50 = -30

x ≤  -30/(-2) = 15

The number of weeks she can withdraw is x ≤ 15 weeks.
