Answer: x=0.25

Step-by-step explanation: 1−8x=−16x2

Simplify both sides of the equation.

−8x+1=−16x2

Subtract -16x^2 from both sides.

−8x+1−−16x2=−16x2−−16x2

16x2−8x+1=0

16x2+−8x+1=0

Use quadratic formula with a=16, b=-8, c=1.

100 POINTS!!! SHOW ALL WORK PLZ!!! Tarah bought 42 shares of a company’s stock for $16.45 / share. She pays a broker a commission of $7 to buy and
sell stock. After one year, Tarah sold all her shares, when they were worth $20.64 / share.

How much did it cost Tarah to buy the stock? Show your work.

What was Tarah’s net gain or loss? Show your work.

What was Tarah’s annual rate of return? Show your work, make answer a % and then round to tenths place.

Answers

Answer:

`a) $697.90

b) $161.98 gain

c) 23.2096% annual return rate

Step-by-step explanation:

a) $16.45 for one share. 42 shares will cost 16.45 x 42 = $690.90

As she used a broker and paid $7, the total cost for Tarah would be $697.90

b) After the investment, Tarah's gain is $20.64 per stock and she had bought 42. So the total income would be 20.64 x 42 = $866.88. However, she used a broker to sell the stocks as well, so the total gain would only be 859.88.

Overall, the cost was -697.90+859.88 = 161.98 net gain.

c) The rate of return would be the percentage of the original price of stocks that is equal to the net gain. What we are trying to find here is:

What percentage of 697.90 is 161.98?

We can find this percentage by doing a simple division (161.98/697.90) which gives us an answer of 0.232096

In percentages, multiply this decimal by 100 to get a 23.2096% annual return.

The equation of a circle is x2 + y2 - 12y + 20 = 0
What are the coordinates of the center and the length of the radius of the circle?

Answers

Answer:

Center: (0, 6); radius = 4

Step-by-step explanation:

x^2 + y^2 - 12y + 20 = 0

We must complete the square in y.

x^2 + y^2 - 12y = -20

x^2 + y^2 - 12y + 36 = -20 + 36

x^2 + (y - 6)^2 = 16

(x - 0)^2 + (y - 6)^2 = 4^2

Center: (0, 6); radius = 4

draw the line of reflection that reflect quadrilateral ABCD onto quadrilateral A'B'C'D

Answers

Answer:

-3 across the x

Step-by-step explanation:

negative 3 is in the middle of the two, both between point -1 and -5, and point 0 and -6.

When a shape is reflected, it must be reflected over a line. The line of reflection of quadrilateral ABCD onto quadrilateral A'B'C'D is [tex]y = -3[/tex]

From the given graph, we have the following observations

ABCD was flipped over to form A'B'C'D'The line of reflection is between both shapes

Using points C and C' as reference;

We have:

[tex]C = (-3,-1)[/tex]

[tex]C' = (-3,-5)[/tex]

Notice that both points have the same x-coordinate

This means that the line of reflection is parallel to the x-axis, and it passes through the y-axis.

The point at which it passes through the y-axis is calculated using mid-point formula.

So, we have:

[tex]y = \frac{y_1 + y_2}{2}[/tex]

[tex]y = \frac{-1-5}{2}[/tex]

[tex]y = \frac{-6}{2}[/tex]

[tex]y = -3[/tex]

Hence, the line of reflection is [tex]y = -3[/tex]

See attachment for the line of reflection

Calculate the lower bound and upper bound for Helen's value of .
Give your answers correct to 3 decimal places.​

Answers

Answer:

lower bound: 2.996

upper bound: 3.244

Step-by-step explanation:

The value that Helen wants to use is Pi = C/D. The lower bound value is 3.065, and the upper bound for Helen's value is 3.165.

What is circumference?

The circumference is the perimeter of the circle.

Given, the circumference, C, at 405 mm to three significant numbers.

She correctly estimates the diameter, d, to be 130 mm to two significant numbers.

Helen wants to find the value of Pi using the formula pi=C/D

We have, the circumference of the circle = C = 405 mm

The diameter of the circle = d = 130 mm

Pi = C/D

= 405 mm / 130 mm

= 405 / 130

= 3.115

3.115, measured to the nearest 0.1.

The degree of accuracy is nearest 0.1.

0.1/2 = 0.05

Upper bound = 3.115 + 0.05 = 3.165

Lower bound = 3.115 - 0.05 = 3.065

Therefore, the lower bound and upper bound for Helen's value are 3.165, and 3.065.

Answer:

26

Step-by-step explanation:

Use the Pythagorean Theorem.

c^2 = a^2 + b^2

a = 10

b = 24

c = ?

c^2 = 10^2 + 24^2

c^2 = 100 + 576

c^2 = 676

sqrt(c^2) = sqrt(676)

c = 26

A wooden board is leaning against a wall. The base of the board is 10 feet from the base of the wall. The base of the board forms a 35° angle with the ground.

What is the length of the wooden board?

Round your answer to nearest tenth.

Answers

Answer:

The length of the wooden board is about 12.2 feet.

Step-by-step explanation:

Please refer to the diagram attached below.

The base of the board forms a 35° degree angle with the ground.

And we want to find the length of the wooden board.

Since we are given an angle and its adjacent length and we want to find the hypotenuse, we can use the cosine ratio:

[tex]\displaystyle \cos(\theta^\circ)=\frac{\text{adjacent}}{\text{hypotenuse}}[/tex]

The adjacent side is the distance from the wall to the board, which is 10 feet.

And the angle made is 35°.

The hypotenuse is the length of the wooden board. Therefore:

[tex]\displaystyle \cos(35)=\frac{10}{\ell}[/tex]

Solve for the length. Cross-multiply:

[tex]\displaystyle 10=\ell \cos(35)[/tex]

Therefore:

[tex]\displaystyle \ell=\frac{10}{\cos(35)}\approx12.2[/tex]

The length of the wooden board is about 12.2 feet.

Triangle STU is rotated 270 clockwise about the origin to create triangle S'T'U'. If point U of triangle STU is a (a,b), which algebraic representation best describes point U' of triangle S'T'U'?

Answers

Answer:

(b, -a)

Step-by-step explanation:

First note that the rule for a rotation by 270° about the origin is (x,y)→(y,−x)

Note that the coordinates were swapped and the x coordinates negated. Similarly;

Given the coordinate of the point U as (a, b), if the triangle is rotated 270degrees clockwise, the resulting coordinate will  be (b, -a)

The base of an isosceles triangle is 16 cm long. The equal sides are each 22 cm long. Find the height of the triangle.

Answers

Given:

The base of an isosceles triangle is 16 cm long.

The equal sides are each 22 cm long.

To find:

The height of the triangle.

Solution:

We know that the altitude of an isosceles triangle divides the base into two equal parts as shown in the below figure.

According to the Pythagoras theorem:

[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]

Using Pythagoras theorem, we get

[tex]22^2=h^2+8^2[/tex]

[tex]484=h^2+64[/tex]

[tex]484-64=h^2[/tex]

[tex]420=h^2[/tex]

Taking square root on both sides, we get

[tex]\sqrt{420}=h[/tex]                  (Because side cannot be negative)

[tex]2\sqrt{105}=h[/tex]

Therefore, the height of the isosceles triangle is [tex]2\sqrt{105}[/tex] cm. Approximate height is 20.49 cm.
