find the value of 10z when z =0.8

Answers

Answer 1
z will equal 80. okay?
Answer 2

Answer:

So, your answer to 10z would be 8.

Step-by-step explanation:

All you need to do is plug in 0.8 for z. A cool trick when multiplying by ten is you can move the decimal point over 1 to the right. So, 0.8 would become 08.0, aka 8.

The altitude to the hypotenuse of a right triangle divides the hypotenuse into two segments measuring 11 cm and 5 cm. To the nearest tenth, what is the length of the shorter leg of the triangle?

Answers

Answer:

8.4 cm

Step-by-step explanation:

Given that:

A right angled triangle, let [tex]\triangle ABD[/tex]. Right angled at [tex]\angle A[/tex].

Altitude AC to the hypotenuse BD.

Length of side BC = 5 cm

Length of side CD = 11 cm

We have to find the value of shorter leg of triangle. i.e. side AB = ?

Using the concept of similarity, we can say the following:

[tex]\dfrac{AB}{BC} = \dfrac{BD}{AB}\\\Rightarrow AB^2=BC.BD\\\Rightarrow AB^2=5\times (5+11)\\\Rightarrow AB^2=5\times 16\\\Rightarrow AB^2=80\\\Rightarrow AB=\sqrt{80}\\\Rightarrow \bold{AB\approx 8.4\ cm}[/tex]

The length of shorter leg of the triangle = 8.4 cm

What are trigonometric relations?

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin θ = opposite / hypotenuse

cos θ = adjacent / hypotenuse

tan θ = opposite / adjacent

tan θ = sin θ / cos θ

cosec θ = 1/sin θ

sec θ = 1/cos θ

cot θ = 1/tan θ

Given data ,

Let the triangle be ΔABC , where ∠B = 90°

Let the side AB be x

So , the adjacent side = x

The angle of the triangle ∠A is = 72°

So , θ = 72°

The hypotenuse AC = 8

And , by trigonometric relations , we get

cos θ = adjacent / hypotenuse

Substituting the values in the equations , we get

cos 72° = x / 8

Multiply by 8 on both sides , we get

x = cos 72° × 8

Now , cos 72° = 0.30901

Substituting the value of cos 72° , we get

x = 0.30901 × 8

x = 2.472

Hence , the value of x is determined by cosine function

Answer:

[tex]y = \frac{4}{3}x - 12[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (3,-8)[/tex]

[tex](x_2,y_2) = (6,-4)[/tex]

Required

Determine the equation

First, we need to determine the slope (m):

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{-4 - (-8)}{6 -3}[/tex]

[tex]m = \frac{-4 +8}{3}[/tex]

[tex]m = \frac{4}{3}[/tex]

Next, we determine the line equation using:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex]m = \frac{4}{3}[/tex]

[tex](x_1,y_1) = (3,-8)[/tex]

[tex]y - (-8) = \frac{4}{3}(x - 3)[/tex]

[tex]y +8 = \frac{4}{3}(x - 3)[/tex]

[tex]y +8 = \frac{4}{3}x - 4[/tex]

[tex]y = \frac{4}{3}x - 4 - 8[/tex]

[tex]y = \frac{4}{3}x - 12[/tex]

The equation of the line that passes through  (3, -8)(6, -4) is y = - 1 / 2 x - 1

The slope intercept equation is as follows:

y = mx + b

where

m = slope

b = y-intercept

Therefore,

The line passes through (3, -8)(6, -4)

m = -4 - 3 / 6 + 8 = -7 / 14 = - 1 / 2

y = - 1 /2 x + b

let's find b using (6, -4)

-4 = - 1 /2 (6) + b

-4 + 3 = b

b = -1

Therefore,

y = - 1 / 2 x - 1

Answers

Answer:

x = 1

Step-by-step explanation:

5x + 17 = 1/2[(73x + 5) - (23x - 5)]

5x + 17 = 1/2[37x + 5 - 23x + 5]

5x + 17 = 1/2[14x + 10]

5x + 17 = 1/2 * 2(7x + 5)

5x + 17 = 7x + 5

5x - 17x = 5 - 17

-12x = - 12

x = - 12/-12

x = 1

A circle is a curve sketched out by a point moving in a plane. The value of x that will make the Secant and Tangent Angles true for the circle is 17/25.

What is a circle?

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

For the given circle, as per the Secant and Tangent Angles theorem, the measure of the angle formed by two tangents can be written as,

∠WVU = (arc WU + arc WU)/2

5x + 17 = [(37x + 5) + (23x - 5)]/2

2(5x + 17) = (37x + 5) + (23x - 5)

10x + 34 = 37x + 5 + 23x - 5

10x - 37x - 23x = 5 - 5 - 34

-50x = -34

x = 34/50

x = 17/25

Hence, the value of x is 17/25.

Find the distance between each pair of parallel lines with the given equations y=3x, y=3x+10

Answers

Answer:

sqrt10

Step-by-step explanation:

Since the closest distance between two parallel lines is a line that is perpindicular to them, we first find the line of the slope that is perpindicular to both lines. Since slope of line y = 3x+10 is 3, the slope of the line that is perpinduclar is -1/3. Therefore y = -1/3x is perpindicluar to both lines. We then find the intersection point of each line. We find said points by setting the lines equal to each other. 3x+10=-1/3x, x = -3 therefore y = 1. For the second line we get we find the origin is the intersection. Therefore since this forms a right triangle with the x axis, we find that the distance is 3^2+1^2 = sqrt10

Mr. Thompson plans to invest $7,500 in a savings account that earns 2.75% simple annual interest. If he makes no other deposits or withdrawals, how much money will Mr. Thompson's account be worth after 10 years.

Answers

Answer:

Mr. Thompson's account be worth $9,562.50 after 10 years

Step-by-step explanation:

Simple Interest

Interest is calculated on the original principal only of a loan or on the balance of an account.

Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.

The interest earned is calculated as follows:

I=P.r.t

Where:

I = Interest

P = initial principal balance

r = interest rate

t = time

Mr. Thompson plans to invest P=7,500 in a savings account that earns r=2.75% = 0.0275.

The interest earned in t=10 years is calculated now:

I=7,500*0.0275*10

I=2,062.50

Now we add the interest to the principal:

A = $7,500 + $2,062.50

A = $9,562.50

Mr. Thompson's account be worth $9,562.50 after 10 years

(2) If da Vinci did have exotropia, in which an eye turns outward, he would not have been the only artist in history with that condition.(3) Christopher Tyler, a visual neuroscientist at City University of London, noticed a pattern in da Vincis portraits and in works depicting the great artist. (4) While few self-portraits of da Vinci exist, Tyler argues that many of da Vincis portraits reflect his appearance. (5) As the great artist himself said, the soul guides the painters arm and makes him reproduce himself, since it appears to the soul that this is the best way to represent a human being.(6) To test his theory that da Vinci had exotropia, Tyler studied the eye alignments of the subjects of six pieces of art that purportedly depict the Renaissance artist himself, including da Vincis Vitruvian Man and Salvator Mundi and Andrea del Verrocchios sculpture David. (7) The results confirmed Tylers suspicions: da Vinci likely had exotropia, with one eye turning out at -10.3 degrees.(8) Tylers findings, which he published in JAMA Ophthalmology, created a stir in both the art and science communities. (9) Only about 1 percent of the population has exotropia, yet previous studies have suggested that other famous artistslike Rembrandt, Picasso, and Degashad it as well, which indicates that the eye condition was more common in centuries past than it is now. (10) Tyler believes that da Vincis condition was intermittentthat is, his eye drifted out of alignment when he was relaxed, but when he focused, it would realign. (11) If Tyler is right and da Vinci could control his exotropia, then the artist could switch from 2-D to 3-D vision, enhancing his ability to accurately capture three-dimensional figures on a two-dimensional canvas.The writer is working on a revision of the passage and has written the following thesis statement for it.Based on the evidence from Tylers studies, it is clear that this condition was the primary reason for da Vincis success.Which of the following is most likely the main claim that the writer is planning to make in the new version of the passage?The only way for an artist to be successful is to have exotropia.ADa Vinci was more successful as an artist than others who also had exotropia.BStudying just a few works of art can provide compelling information about an artists physical conditions.CThe only way to fully understand an artists work is to study the artists physical conditions.DDa Vinci was a great artist because he had exotropia.EIs it E?
