Answer:

172.8

Step-by-step explanation:

72% of 240 is 172.8

You can estimate it by rounding 172.8 to $173

Jules's take $173 for home pay.

What is Percentage?

A relative value indicating hundredth part of any quantity is called percentage.

Given that;

Total earning of Jules's = $240

He take home pay is about 72%.

Now,

Amount for take home pay = 72% of $240

It can be solve as;

72% of $240

72% × 240

72/100 × 240

72/10 × 24

172.8

After estimating we get;

Amount for take home pay = $173

Thus, Jules's take $173 for home pay.

( 2 ,6.5 ) lied on the parabola which mean when we put the x=2 in the equation the y value would be 6.5 :

\(6.5 = a \times ({2 - 1})^{2} + k\)

\(6.5 = a + k \: \: \: \: \: \: \: ( \alpha )\)

In the otherhand ( -1 , - 1 ) has the same condition:

\( - 1 = a \times ({ - 1 - 1})^{2} + k\)

\( - 1 = 4a + k \: \: \: \: \: \: \: \: ( \beta )\)

_____________________________________________

\(4a + k = - 1 \: \: \: \: \: \: \: \: \: \: ( \alpha )\)

\(a + k = 6.5 \: \: \: \: \: \: \: \: ( \beta )\)

Multiply Beta by (-1) :

\(4a + k = - 1\)

\( - a - k = - 6.5\)

then we have to find the submission of alpha and beta :

\( \alpha + \beta \)

\(4a - a + k - k = - 1 - 6.5\)

\(3a = - 7.5\)

Divide both sides by 3

\( \frac{3a}{3} = \frac{ - 7.5}{3} \\ \)

\(a = - 2.5\)

Put the value of a in one of the above equations to find the value of k .I'm gonna use the second equation ( beta ) :

\(a + k = 6.5\)

\( - 2.5 + k = 6.5\)

Add both sides by 2.5

\( - 2.5 + 2.5 + k = 6.5 + 2.5\)

\(k = 9\)

Thus the equation of the parabola is :

\(y = - 2.5 ({x - 1})^{2} + 9\)

The maximum value of the parabola is for the vertex which is x = 1 , so we have to put it in the equation and find it's y coordinate :

\(y = - 2.5 ({1 - 1})^{2} + 9\)

\(y = - 2.5 \times {0}^{2} + 9\)

\(y = 0 + 9\)

\(y = 9\)

Step-by-step explanation:

The exact value of cot A is .20/21

The denominator means moving the radical term square root or cube root to the numerator such that a denominator is a whole number.

We have been given that sin( A ) = 21/29 and angle A is in quadrant 1. We are asked to find the exact value of  cot (A) in simplest radical form.

We know that sine relates opposite side of right triangle with hypotenuse.

Since = opposite

            hypotenuse

This means that opposite side is 21 units and hypotenuse is 29 units.

We know that cotangent relates adjacent side of right triangle with adjacent side.

Cot = Adjacent

         opposite

Now we will find adjacent side using Pythagoras theorem as:

Adjacet² = hypotenuse² - opposite²

Adjacent² = 29² - 21²

Adjacent² = 841 - 441

Adjacent² =400

Let us take positive square root on both sides:

√Adjacent² = √400

 Adjacent = 20

Therefore, adjacent side of angle A is 20 units.

Cot (A) = 20/21

The exact value of cot A is .20/21

Answer:

-7π/3 or -420 degrees

Step-by-step explanation:

So we know that the arrow has made one full rotation and that it is moving in a clockwise direction. So already we have -2π degrees.

The arrow stops at π/6 before the next π/2 rotation. Therefore we find the difference between the two.

π/2 - π/6

3π/6 - π/6 = 2π/6

π/3

Since this is still clockwise, we make this negative. So the measure of the angle shown by the arrow is -2π - π/3

Answer:

Henry had the best record for the number of shots made

Step-by-step explanation:

From the given information.

Four friends are on a basketball team.

Henry

Allison

Arthur

Trevor

We are being told that Henry made 0.45  of his shots out of all his attempts

Allison made Arthur made of her shots  of his shots.

i,e Arthur did the work for Allison , so out of Arthur's shot , we have to  figured out Allison shots,

Trevor missed 58% of his shots.

i.e Trevor failed 0.58 of his shot, If he failed 0.58 shot

Then the attempts Trevor made is :

= 1 - 0.58

= 0.42

SO , Trevor made 0.42 shots out of all his attempt

N:B We are not given any information about Arthur's shots , so we can't determine Allison shot as well.

Therefore; we will focus on only Henry and Trevor shots

So ;

Henry made 0.45  of his shots

Trevor made 0.42 out of his shots

We can thereby conclude that :

Henry had the best record for the number of shots made

Answer:

The standard form of the equation of a circle with center at (h, k) and radius r is:

(x - h)^2 + (y - k)^2 = r^2

We are given that the center of the circle is (4, -1), so h = 4 and k = -1. We also know that the circle passes through the point (-4, 1), which means that the distance from the center of the circle to (-4, 1) is the radius of the circle.

The distance between two points (x1, y1) and (x2, y2) is given by the distance formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

So the radius of the circle is:

r = sqrt((-4 - 4)^2 + (1 - (-1))^2) = sqrt(100) = 10

Now we can substitute the values of h, k, and r into the standard form equation of a circle:

(x - 4)^2 + (y + 1)^2 = 10^2

Expanding the equation gives:

x^2 - 8x + 16 + y^2 + 2y + 1 = 100

Simplifying and putting the equation in standard form, we get:

x^2 + y^2 - 8x + 2y - 83 = 0

Therefore, the equation in standard form of the circle with center at (4, −1) and that passes through the point (−4, 1) is:

x^2 + y^2 - 8x + 2y - 83 = 0

To support her discussion, it would be best for Alex to use Graph A for her presentation. Alex should use this graph for her presentation because the number of faulty products appears to decrease less on this graph.

In Mathematics and Geometry, a steeper slope simply means that the slope of a line is bigger than the slope of another line. This ultimately implies that, a graph with a steeper slope has a greater (faster) rate of change in comparison with another graph.

In order to determine an equation with a declining line, we would have to determine the slope of each line graphically and then taking note of the line with a negative rate of change (slope) because it indicates a decreasing function.

In this context, we can reasonably infer and logically deduce that Graph A is more suited for Alex's presentation because the number of faulty products appears to decrease less on it.

Answer:

  25 yards long, 5 yards wide

Step-by-step explanation:

The given parameters can be used with the area and perimeter formulas for a rectangle to form an equation that can be solved for the dimensions.

The length and width can be represented by x and y. The formulas for area and perimeter give two equations relating these two variables:

  A = LW   ⇒   125 = xy

  P = 2(L+W)   ⇒ 60 = 2(x +y)

Using the second equation to write an expression for y, we have ...

  y = 30 -x

Substituting into the first equation gives ...

  125 = x(30 -x)

This suggests we can find x by looking for factors of 125 that total 30.

  125 = 1(125) = 5(25)

Factor totals are 126 and 30. This means we have ...

  x = 5, y = 30-5 = 25

or

  x = 25, y = 30 -25 = 5

The rectangle dimensions are 5 yards by 25 yards.

Answer: To find A and B such that g(x) = f(x) is bijective, we need to ensure that g(x) satisfies the conditions for a bijective function, namely, that it is both injective and surjective.

To show that g(x) is injective, we need to show that for any distinct x1, x2 in A, g(x1) ≠ g(x2). We can do this by assuming that g(x1) = g(x2) and then showing that it leads to a contradiction.

So, let's assume that g(x1) = g(x2). Then, we have:

f(x1) = f(x2)

x1(x1-1) = x2(x2-1)

x1^2 - x1 = x2^2 - x2

x1^2 - x2^2 - x1 + x2 = 0

(x1 - x2)(x1 + x2 - 1) = 0

Since x1 and x2 are distinct, we must have x1 + x2 = 1.

But this is impossible, since x1 and x2 are both real numbers, and the sum of two real numbers cannot equal 1 unless one of them is complex. Therefore, our assumption that g(x1) = g(x2) must be false, and g(x) is injective.

To show that g(x) is surjective, we need to show that for any y in B, there exists at least one x in A such that g(x) = y. In other words, we need to find an expression for x in terms of y.

So, let's solve the equation f(x) = y for x:

x(x-1) = y

x^2 - x - y = 0

Using the quadratic formula, we get:

x = (1 ± √(1 + 4y))/2

Since we want to define g(x) on R, we need to ensure that the expression under the square root is non-negative. This means that 1 + 4y ≥ 0, or y ≥ -1/4.

Therefore, we can define A = [-1/4, ∞) and B = [0, ∞), and g(x) = f(x) is a bijective function from A to B.
