Answer:

93%

Step-by-step explanation:

Formula for calculating average = sum of data/ total number of data

Step 1: Add all percentages

Let the percentage on the last test be x

82% + 75% + 90% + x = 247% + x

Step 2: Apply the formula

Average = sum of percentages/ total number of tests

85 = 247 + x /4

340 = 247 + x

x = 340 - 247

x = 93%

Therefore, Briana must receive 93% on her final test to maintain an average of 85%.

Sample Response: A quadratic function in standard form is converted to vertex form by completing the square. The first two terms are used to create a perfect square trinomial after a zero pair is added. The zero pair is found by taking half of the x-term coefficient and squaring it. The original constant term and the negative value of the zero pair are then combined.

To prove a projectile's trajectory is parabolic, we start with the horizontal motion equation, solve for time, and substitute into the vertical motion equation, ending up with a quadratic equation in the form of y = ax + bx², showing parabolic motion.

To prove that the trajectory of a projectile is parabolic, we start with the two separate equations for horizontal and vertical motion. The horizontal motion equation is given by x = Voxt, where Vox is the horizontal velocity component. We solve this for time t to get t = x / Vox. We then substitute this expression for t into the vertical motion equation y = Voyt - 1/2gt2, where Voy is the vertical velocity component and g is the acceleration due to gravity.

Substituting t = x / Vox into the vertical equation, we get y = Voy(x / Vox) - (1/2)g(x / Vox)2. This simplifies to y = (Voy/ Vox)x - (g / 2Vox2)x2, which is of the form y = ax + bx2, proving that the trajectory is parabolic with a and b as constants.

Answer:

4) (1,-1)

Step-by-step explanation:

Let the points be

[tex](x_1,y_1) = K(-5,-4)\\(x_2,y_2) = L(5,1)\\[/tex]

The formula for finding the coordinates of point that divides the line in a:b is:

[tex]x = \frac{bx_1+ax_2}{a+b} \\y = \frac{by_1+ay_2}{a+b}[/tex]

Here x and y are the coordinates of the point that will partition the line into given ratios

Our ratio is 3 to 2,

So,

a=3

b=2

Putting the values in the formula

[tex]x = \frac{(2)(-5)+(3)(5)}{3+2}\\x = \frac{-10+15}{5}\\x =\frac{5}{5}\\ x =1\\y = \frac{(2)(-4)+(3)(1)}{3+2}\\y = \frac{-8+3}{5}\\y = \frac{-5}{5}\\ y = -1[/tex]

Hence, the correct answer is:

The coordinate of the point on the directed line segment is (1, -1). Then the correct option is D.

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of line, etc.

The coordinates of the point on the directed line segment from K (-5,-4) to L (5,1) portions the segment into a ratio of 3: 2.

Let the coordinate of the point be (x,y).

m₁: m₂ = 3: 2

(x₁, y₁) = (-5, -4)

(x₂, y₂) = (5, 1)

Then we have

Answer:

930

Step-by-step explanation:

To use the division method

Write the given numbers in a horizontal row separated by commas.

Divide them by a suitable prime number

Place the quotient under the numbers in the next row. If a number is not divided exactly then bring it down to the next row.

Repeat the process until only co prime numbers are left in the last row.

Multiply all the prime numbers used as divisors.

The product is the LCM

Given 30 and 62, then

2 | 30, 62

3 | 15, 31

5 | 5, 31

31 | 1, 31

    | 1, 1 ← co primes left

Hence LCM = 2 × 3 × 5 × 31 = 930

Question 7

Answers:

Jane's Uber business has the function f(x) = 0.10x+5

Joe's Uber business has the function f(x) = 0.20x+4

x is the number of miles, f(x) is the total cost for the customer

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

Explanation:

Jane charges $5 no matter how many miles are driven. This is the base fee. On top of this base fee, an additional price is charged based on the number of miles driven. If Jane drives 1 mile, then an additional 0.10*1 = 0.10 dollars is added on. If 2 miles are driven, then 0.10*2 = 0.20 dollars is added on. And so on.

In general, an additional 0.10*x dollars is added on the base fee to get the total cost to be 5 + 0.10x which rearranges to 0.10x + 5. That's how I ended up with f(x) = 0.10x + 5

Joe's equation will be constructed in a similar way. His base fee is $4 and you add on 0.20x dollars (since it costs $0.20 per mile for Joe's company). Overall, we get f(x) = 0.20x + 4 for Joe's company.

Note how your teacher is not asking you to solve for x or f(x). If you want, you can replace f(x) with y; however, this isn't in function notation.

Question 8

Answers:

Function for Joseph's plan is: f(x) = 0.10x + 20

Function for Micki's plan is: f(x) = 0.15x + 10

The plans cost the same when 200 text messages are sent

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

Explanation:

We'll set up the equations in a similar way done in problem 7. We start with $20 as the base fee for Joseph's plan and then add on 0.10x dollars because $0.10 is charged per text message. We have x represent the number of text messages. Joseph's function is therefore f(x) = 0.10x + 20. Similarly, Micki's function is f(x) = 0.15x + 10

Let's replace f(x) with y and we have these two equations: y = 0.10x + 20 and y = 0.15x + 10

Now use substitution to solve for x and y

y = 0.10x + 20

0.15x + 10 = 0.10x + 20 ... y replaced with 0.15x+10

0.15x-0.10x = 20-10

0.05x = 10

x = 10/0.05

x = 200

This means that the two plans cost the same when 200 messages are sent.

Note plugging x = 200 into each f(x) function leads to

f(x) = 0.10x + 20

f(200) = 0.10*200 + 20

f(200) = 20 + 20

f(200) = 40 <<--- it costs Joseph $40 to send 200 messages

and

f(x) = 0.15x + 10

f(200) = 0.15*200 + 10

f(200) = 30 + 10

f(200) = 40 <<--- it costs Micki $40 to send 200 messages

Answer:

A

Step-by-step explanation:

The table of values is linear so we can express the function as

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 6, - 4) and (x₂, y₂ ) = (- 3, - 2) ← ordered pairs from the table

m = [tex]\frac{-2+4}{-3+6}[/tex] = [tex]\frac{2}{3}[/tex]

Note the ordered pair (0, 0) ⇒ c = 0

Then, you get this function h(x):

 [tex]h(x)=f(x)-g(x)\\\\h(x)= (4x^2+6x)-(3x^2-x)\\\\h(x)=4x^2+6x-3x^2+x\\\\h(x)=x^2+7x[/tex]

Answer:

$29,000

Step-by-step explanation:

Given:

Receivable draw per week= $11,00

Commission on all sales= 12%

Sale for the month= $205,000

weeks in a month= 4

Jim's commission after the draw=?

total draws= 11,00 (4)

                  = 44,00

Commission on the sale= 205000(0.12)

                                        =24600

Jim's commission after the draw= 4400 +24600

                                                     =29,000 !

Jim Smith's commission after the draw is calculated by determining his total commission from sales and then subtracting the draw he receives weekly. For a month where he made $205,000 in sales, his commission after the draw is $20,200.

The subject of this question is Jim Smith's commission after the draw, who works as a salesman and receives a draw of $1,100 per week plus a 12% commission on all sales. Considering that Jim made $205,000 in sales for the month, we would first calculate his total commission by multiplying the sales amount by the commission percentage. Next, we deduct the total draw for the month from the total commission to find Jim's commission after the draw.

To calculate the total commission earned, you would use the formula: Commission = Sales x Commission Rate. Therefore, for a sales amount of $205,000 and a commission rate of 12%, the total commission would be $205,000  x 0.12, which equals $24,600. Since a month is considered to have four weeks, Jim's total draw for the month would be $1,100 x 4, totaling $4,400.

To find out how much commission Jim has after accounting for the draw, we subtract the draw from the total commission: Commission after Draw = Total Commission - Total Draw, or $24,600 - $4,400, which equals $20,200.

Answer:

C. (-2,2π/3)

Step-by-step explanation:

Given:

In the given plane, each line represents angles and the circles shows the radii. Now as full circle is of 360 degrees or 2π and there are 12 straight lines that means

every angle is π/6 apart (30 degrees).

As the given red point is on circle 2, this means the radii, r=2

and Ф=300 degrees or 5π/3

r=(2,5π/3)

but above is not given in the options.

Polar coordinates can have positive or negative theta and also have positive or negative radii. In case of negative radii the polar coordinate moves in opposite direction of the pole.

if we consider r=-2 then we have to move in opposite direction of pole of  Ф=300 degrees or 5π/3 is 120 degrees or 2π/3.

hence r=-2 andФ=2π/3

Correct option is C:(-2,2π/3)!

Second one is growing by a factor of 2 because the exponent on 2 tells me that 2 is is being repeated as a factor.

If x=0 then 15*2^0=15(1)=15 which is what we have initially.

Final answer:

The correct option is f(x)=15⋅2^x. The function that best models the cell growth after x hours is f(x) = 15⋅ 2^x, illustrating the exponential nature of cell division starting with 15 cells.

Explanation:

The amount of cells in the laboratory after x hours, when the number of cells doubles every hour, is best represented by the function f(x) = 15⋅ 2^x. This is because the cell population increases exponentially, starting with 15 cells and doubling each hour. The formula represents exponential growth where the original amount of cells (15) is multiplied by two raised to the power of the number of hours elapsed (x).
