The area of the triangle is 16. 

You can find this by plotting each of the points and drawing the triangle. You can then use the distance formula to determine each side length. The rectangle will be 2 on one side and 4 on the other. When multiplied together, it will give you the above answer

The coordinates of the midpoints for each side are (2.5, 5.5) , (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5).

And, yes, the midpoints are the vertices of a rectangle, as its opposite sides are the same in length.

Use the formula for the midpoint of two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are,

[tex][\dfrac{(x_1 + x_2)}{2} , \dfrac{(y_1 + y_2)}{2} ][/tex]

Given that,

Vertices of the rectangle are (0, 8), (5, 3), (4, 2), and (- 1, 7).

Hence, the coordinates of the midpoints for each side are calculated by using the above formula,

The midpoint of two points (0, 8) and (5, 3) are,

[tex](\dfrac{(0 + 5)}{2} , \dfrac{(8 + 3)}{2} )[/tex]

[tex](2.5, 5.5)[/tex]

The midpoint of two points (5, 3) and (4, 2) are,

[tex](\dfrac{(5 + 4)}{2} , \dfrac{(3 + 2)}{2} )[/tex]

[tex](4.5, 2.5)[/tex]

The midpoint of two points (4, 2) and (-1, 7) are,

[tex](\dfrac{(4 - 1)}{2} , \dfrac{(2 + 7)}{2} )[/tex]

[tex](1.5, 4.5)[/tex]

The midpoint of two points (-1, 7) and (0, 8) are,

[tex](\dfrac{(-1 + 0)}{2} , \dfrac{(8 + 7)}{2} )[/tex]

[tex](-0.5, 7.5)[/tex]

Therefore, the coordinates of the midpoints for each side are (2.5, 5.5) , (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5).

When the coordinates of vertices are rectangular then opposite sides are equal to each other.

So, we can check the length of each side of the coordinates of the midpoints (2.5, 5.5), (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5).

Used the distance formula,

The distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is,

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

So, The distance between the two points [tex](2.5, 5.5)[/tex] and [tex](4.5, 2.5)[/tex],

[tex]d = \sqrt{(4.5- 2.5)^2 + (2.5 - 5.5)^2}[/tex]

[tex]d = \sqrt{4 + 9}[/tex]

[tex]d = \sqrt{13}[/tex]

The distance between the two points [tex](4.5, 2.5)[/tex] and [tex](1.5, 4.5)[/tex],

[tex]d = \sqrt{(4.5- 1.5)^2 + (2.5 - 4.5)^2}[/tex]

[tex]d = \sqrt{9 + 4}[/tex]

[tex]d = \sqrt{13}[/tex]

The distance between the two points [tex](1.5, 4.5)[/tex] and [tex](-0.5, 7.5)[/tex]

[tex]d = \sqrt{(1.5+ 0.5)^2 + (7.5 - 4.5)^2}[/tex]

[tex]d = \sqrt{4 + 9}[/tex]

[tex]d = \sqrt{13}[/tex]

The distance between the two points[tex](-0.5, 7.5)[/tex] and [tex](2.5, 5.5)[/tex]

[tex]d = \sqrt{(2.5+ 0.5)^2 + (7.5 - 5.5)^2}[/tex]

[tex]d = \sqrt{9 + 4}[/tex]

[tex]d = \sqrt{13}[/tex]

Clearly, All the lengths of each side of the coordinates of the midpoints (2.5, 5.5), (4.5, 2.5), (1.5, 4.5), and (- 0.5, 7.5) are the same.

Hence, it forms a rectangle, as its opposite sides are also the same in length.

Answer:

Rotated about an axis

Step-by-step explanation:

APEX

Reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.

Consider a plane. Consider a design or shape on that plane. Now consider an axis.

If we think of that axis as a mirror, and on the opposite side of that axis create the image of the considered shape, then if the shape's image looks exactly as the shape itself, then that shape is called to have a reflectional symmetry.

Instead of that mirror intuition, we can also think that we sort of rotated that image about that considered axis, and after half rotation, the figure is again onto its plane. If that rotated figure looks alike to the initial figure, then that figure has rotational symmetry.

Thus, reflectional symmetry is the quality a design has if it maintains all characteristics when it is (blank) lying in its plane Option: A) rotated about an axis.

The inflation rate in the car is 42%.

Inflation Rate (CPI, annual variation in %) Inflation refers to an overall increase in the Consumer Price Index (CPI), which is a weighted average of prices for different goods.

Sarah bought a car last year to drive back and forth to work after she spent $1,098 on gas this year she spent $1,562.

Based on the above information, the calculation is as follows:

[tex]\rm Inflation \ rate=\dfrac{1562-1098}{1098}\\\\ Inflation \ rate=\dfrac{464}{1098}\\\\ Inflation \ rate=0.42\\\\ Inflation \ rate=0.42 \times 100\\\\ Inflation \ rate= 42 \ percent[/tex]

ANSWER

The missing term is 42.

EXPLANATION.

We want to find the missing term of the equivalent ratio. 90:15=_____:7

Let y be the missing term, then

90:15=y:7

We rewrite as fractions to get;

[tex] \frac{90}{15} = \frac{y}{7} [/tex]

Simplify the left ratio:

[tex] \frac{6}{1} = \frac{y}{7} [/tex]

Cross multiply:

[tex]6 \times 7 = 1 \times y[/tex]

[tex]42 = y[/tex]

Therefore the missing term is 42.

To solve this problem, you would have to apply the Pythagorean Theorem: a^2+b^2=c^2

X is the hypotenuse; therefore:

[tex]\frac{\cos\left(2x\right)+\cos\left(4x\right)}{\sin\left(2x\right)-\sin\left(4x\right)}=-\cot\left(x\right)[/tex]

Step-by-step explanation:

[tex]\frac{\cos\left(2x\right)+\cos\left(4x\right)}{\sin\left(2x\right)-\sin\left(4x\right)}[/tex]

Apply formula:

[tex]\cos\left(A\right)+\cos\left(B\right)=2\cdot\cos\left(\frac{A+B}{2}\right)\cdot\cos\left(\frac{A-B}{2}\right)[/tex] and

[tex]\sin\left(A\right)-\sin\left(B\right)=2\cdot\cos\left(\frac{A+B}{2}\right)\cdot\sin\left(\frac{A-B}{2}\right)[/tex]

We get:

[tex]=\frac{2\cdot\cos\left(\frac{2x+4x}{2}\right)\cdot\cos\left(\frac{2x-4x}{2}\right)}{2\cdot\cos\left(\frac{2x+4x}{2}\right)\cdot\sin\left(\frac{2x-4x}{2}\right)}[/tex]

[tex]=\frac{\cos\left(\frac{2x-4x}{2}\right)}{\sin\left(\frac{2x-4x}{2}\right)}[/tex]

[tex]=\frac{\cos\left(\frac{-2x}{2}\right)}{\sin\left(-\frac{2x}{2}\right)}[/tex]

[tex]=\frac{\cos\left(-x\right)}{\sin\left(-x\right)}[/tex]

[tex]=\frac{\cos\left(x\right)}{-\sin\left(x\right)}[/tex]

[tex]=-\cot\left(x\right)[/tex]

Hence final answer is

[tex]\frac{\cos\left(2x\right)+\cos\left(4x\right)}{\sin\left(2x\right)-\sin\left(4x\right)}=-\cot\left(x\right)[/tex]

For this case we have the following expression:

Answer:

Production of  2800  juice boxes is the break even point.

Step-by-step explanation:

Break-even point is the point where profit is zero and number of manufactured goods are all sold

Let number of juice boxes be y

charges of local store for 1 juice box= $0.65

charges of local store for y juice box=$0.65y

Factory cost of y juices boxes= $1400 + $0.15y

Assuming all juice boxes manufactured can be sold, to find the break-even point

charges of local store for y juice box= Factory cost of y juices boxes

$0.65y=$1400 + $0.15y

$0.65y-$0.15y= $1400

$0.50y=$1400

y= 1400/0.5

y=2800

hence production of  2800  juice boxes is the break even point!

Step-by-step explanation:

Answer:

Step-by-step explanation:

-x is common to all three terms.  Thus, -x^3-2x^2-3x = -x(x^2 + 2x + 3).

Use the quadratic formula to find the roots (and thus the factors) of

x^2 + 2x + 3:  a = 1; b = 2; c = 3.

Thus, the discriminant is b^2-4ac, or 4 - 4(1)(3), or -8.

Because this discriminant is negative, x^2 + 2x + 3 has two complex, unequal roots.  They are:

      -2 ± i√8                  

x = --------------  or  -1 ± i*2*√2

Thus, the three factors of the given polynomial are:

-x, (x + 1 + 2i√2), and (x + 1 - 2i√2)

Total charge for wooden pedestal will be $1136

Step-by-step explanation:

Volume of the pedestal will be = volume of cube + volume of the cone

= (Side)³ + [tex]\frac{1}{3}(\pi r^{2}h)[/tex]

= 10³ + [tex]\frac{1}{3}[\pi (\frac{10}{2})^{2}(7)][/tex]

= 1000 + [tex]\frac{1}{3}[\pi 5^{2}(7)][/tex]

= 1000 + [tex]\frac{1}{3}[\pi (25)(7)][/tex]

= 1000 + [tex]\frac{1}{3}[(3.14)(25)(7)][/tex]

= 1000 + 183.17

= 1183.17 cubic inch

Total volume of 12 wooden pedestals = 12 × 1183.17 = 14198 cubic inch

Since charges of the wood is $0.08 per cubic inch

So total charges for pedestal will be = 0.08 × 14198 = $1135.84 ≈ $1136

To determine (f(a+h) - f(a)) for f(x) = x² + 5x, we substitute a+h and a into the function, expand, and subtract to ultimately simplify to 2ah + h² + 5h.

To determine (f(a+h) - f(a)) for f(x) = x² + 5x and simplify, we need to substitute x with a+h and a into the function separately and then find the difference. Here are the steps:

Substitute a+h into f(x) to get f(a+h) = (a+h)² + 5(a+h).

Expand the equation: f(a+h) = a² + 2ah + h² + 5a + 5h.

Substitute a into f(x) to get f(a) = a² + 5a.

Find the difference: (f(a+h) - f(a)) = (a² + 2ah + h² + 5a + 5h) - (a² + 5a).

Simplify the expression: (f(a+h) - f(a)) = 2ah + h² + 5h.

What question do you need answered?

Answer:

Option A.

Step-by-step explanation:

Anastasia worked for = 7 hours per day

Number of weeks she worked = 52 weeks

Number of hours she worked = 7×52

= 364 hours

Per hour earning of Anastasia = $20

Total earning of Anastasia = 364×20

= $7280

Let the monthly expenses of Anastasia = $x

Then total expenses = $12x

At the end of the year total saving = Total earning - Total expenses

= $7280 - 12x

Since she saved $2000 in a year therefore, expression that represents the savings will be

2000 = 7280 - 12x

12x = 7280 - 2000

12x = 5280

x = [tex]\frac{5280}{12}[/tex]
