Rewrite the following equation in slope-intercept form.

10x − 10y = –1 ?


Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:

y = x + 1/10

Step-by-step explanation:

Rewrite the following equation in slope-intercept form: 10x − 10y = –1 ?

slope intercept form: y = mx + b so you are solving for y:

10x − 10y = –1

subtract 10x from both sides:

10x − 10y – 10x = –1 – 10x

-10y = –1 – 10x

divide all terms by -10:

-10y/(-10) = –1/(-10) – 10x/(-10)

y = 1/10 + x

rearrange for slope intercept form: y = mx + b

y = x + 1/10

Answer:

[tex]y=x+\dfrac{1}{10}[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{6.3 cm}\underline{Slope-intercept form of a linear equation}\\\\$y=mx+b$\\\\where:\\ \phantom{ww}$\bullet$ $m$ is the slope. \\ \phantom{ww}$\bullet$ $b$ is the $y$-intercept.\\\end{minipage}}[/tex]

Given equation:

[tex]10x-10y=-1[/tex]

To write the given equation in slope-intercept form, perform algebraic operations to isolate y.

Add 10y to both sides of the equation:

[tex]\implies 10x-10y+10y=10y-1[/tex]

[tex]\implies 10x=10y-1[/tex]

Add 1 to both sides of the equation:

[tex]\implies 10x+1=10y-1+1[/tex]

[tex]\implies 10x+1=10y[/tex]

[tex]\implies 10y=10x+1[/tex]

Divide both sides of the equation by 10:

[tex]\implies \dfrac{10y}{10}=\dfrac{10x+1}{10}[/tex]

[tex]\implies \dfrac{10y}{10}=\dfrac{10x}{10}+\dfrac{1}{10}[/tex]

[tex]\implies y=x+\dfrac{1}{10}[/tex]

Therefore, the given equation in slope-intercept form is:

Answers

The value of the unknown angle is as follows;

How to find the unknown angle?

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, linear angles, vertically opposite angles etc.

Therefore, the angle 4 can be found as follows:

∠4 = 8x + 6 (alternate angles)

Hence,

8x + 6 + 118 = 180(sum of angles on a straight line)

8x = 180 - 118 - 6

8x = 56

divide both sides by 8

x = 56 / 8

x = 7

Therefore,

∠4 = 8(7) + 6 = 56 + 6 = 62 degrees

TRIGONOMETRY Find the length of the longer diagonal of this parallelogram round to the nearest tenth

Answers

Given the parallelogram ABCD

As shown: AB = 4 ft

m∠BAC = 30

m∠BDC = 104

We will find the length of the longer diagonal which will be AC

See the following figure:

The point of intersection of the diagonals = O

The opposite sides are parallel

AB || CD

m∠ABD = m∠BDC because the alternate angles are congruent

So, in the triangle AOB, the sum of the angles = 180

m∠AOB = 180 - (30+104) = 46

We will find the length of OA using the sine rule as follows:

[tex]\begin{gathered} \frac{OA}{\sin104}=\frac{AB}{\sin 46} \\ \\ OA=AB\cdot\frac{\sin104}{\sin46}=4\cdot\frac{\sin104}{\sin46}\approx5.3955 \end{gathered}[/tex]

The diagonals bisect each other

So,

[tex]AC=2\cdot OA=10.79[/tex]

The longer diagonal is AC

Rounding to the nearest tenth

So, the answer will be AC = 10.8 ft

An object was dropped off the top of a building. The function f(x) = -16x2 + 36represents the height of the object above the ground, in feet, X seconds after beingdropped. Find and interpret the given function values and determine an appropriatedomain for the function.

Answers

f(x) = -16x^2 + 36

Where:

f(x) = height of the object

x = seconds after being dropped.

f(-1) = -16 (-1)^2 + 36

f(-1) = -16 (1) + 36

f(-1) = 20

-1 seconds after the object was dropped, the object was 20 ft above the ground.

This interpretation does not make sense, because seconds can't be negative.

f(0.5) = -16 (0.5)^2 + 36

f(0.5) = -16 (0.25) +36

f(0.5) = -4 + 36

f(0.5) = 32

0.5 seconds after the object was dropped, the object was 32 ft above the ground.

This interpretation makes sense in the context of the problem.

f(2) = -16 (2)^2 + 36

f(2) = -16 (4) +36

f(2) = -64+36

f(2) = -28

2 seconds after the object was dropped, the object was -28 ft above the ground.

This interpretation does not make sense in the context of the problem, because the height can't be negative.

Based on the observation, the domain of the function is real numbers in a <- x <-b , possible values of x where f(x) is true.

before the object is released x=0

next, calculate x when f(x)=0 ( after the object hits the ground)

0= -16x^2+36

16x^2 = 36

x^2 = 36/16

x^2 = 2.25

Find a polynomial f(x) of degree 4 with real coefficients and the following zeros.3 (multiplicity 2) , -i

Answers

We are told that we want a polynomial f(x) with the given zeros.

Recall that if we know the zeros oa polynomial, we can write the polynomial by writing the factors (x - zero of the polynomial) and multiply them all together.

For example, if we want a polynomial of degree 2 with zeros at 2 and 3, then the polynomial would be

[tex](x\text{ -2)}\cdot(x\text{ -3)}[/tex]

In this case, we have a polynomial f(x) of degree 4. So far, we know that 3 is a zero and that -i is a zero. So we write the following

[tex]f(x)=(x\text{ -a)}\cdot(x\text{ -b)}\cdot(x\text{ -c) }\cdot\text{ (x -d)}[/tex]

where a,b,c and d are the zeros of f(x). We know that 3 is a zero and that -i is a zero. So we have

[tex]f(x)=(x\text{ -3)}\cdot(x\text{ -b)}\cdot(x\text{ -( -i)) }\cdot(x\text{ -d)}[/tex]

So to fully describe f(x) we need to find the values of b and d. We are told that 3 is a zero of multiplicity 2. This means that the factor (x -3) appears two times in the factorization of f(x). So we can say that b=3. So we have

[tex]f(x)=(x\text{ -3)}\cdot(x\text{ -3) }\cdot(x\text{ +i ) }\cdot(x-d)=(x-3)^2\cdot(x\text{ +i)}\cdot(x\text{ -d)}[/tex]

Now, we need to find the value of d. Note that we are told that -i is a zero of the function. -i is a complex number, so one important property of polynomials is that if a complex number a+bi is a zero of the polynomial, then the number a-bi (which is called the complex conjugate) is also a zero. Note that the complex conjugate of a complex number is calculated by leaving the real part intact and multiplying the imaginary part by -1.

In our case we have the complex number -i. So we can write -i= 0 - 1i . Then, its complex conjugate is i.

So, we have that d=i.

Then our polynomial would look like this

[tex]f(x)=(x-3)^2\cdot(x+i)\cdot(x\text{ -i)}[/tex]

Note that

[tex](x+i)\cdot(x-i)=x^2\text{ -i}\cdot x\text{ + i}\cdot x+1=x^2+1[/tex]

So our polynomial ends up being

[tex]f(x)=(x-3)^2\cdot(x^2+1)[/tex]

The world's largest swimming pool is the Orthalieb pool in Casablanca, Morocco the length is 30 m longer then 6 times the width. If the perimeter of the pool is 1110 Meters what are the dimensions of the pool?

Answers

The length of the rectangular pool is 30m longer than 6 times the width.

Let "x" represent the length of the width, then you can express the dimensions of the pool as follows:

[tex]\begin{gathered} w=x \\ l=6x+30 \end{gathered}[/tex]

The perimeter of the pool is 1110m, this perimeter was obtained using the formula:

[tex]P=2w+2l[/tex]

Replace the formula with the expressions determined for the width and length:

[tex]1110=2(x)+2(6x+30)[/tex]

From this expression, you can determine the value of x:

-First, distribute the multiplications on the right side of the equation:

[tex]\begin{gathered} 1110=2x+2\cdot6x+2\cdot30 \\ 1110=2x+12x+60 \\ 1110=14x+60 \end{gathered}[/tex]

-Second, pass 60 to the left side of the equal sign by applying the opposite operation to both sides of it:

[tex]\begin{gathered} 1110-60=14x+60-60 \\ 1050=14x \end{gathered}[/tex]

-Third, divide both sides of the equation by 14 to determine the value of x:

[tex]\begin{gathered} \frac{1050}{14}=\frac{14x}{14} \\ 75=x \end{gathered}[/tex]

The width of the pool is w= 75 meters

Now you can determine the length of the pool:

[tex]\begin{gathered} l=6x+30 \\ l=6\cdot75+30 \\ l=480 \end{gathered}[/tex]

[tex]\begin{gathered} x_1=14;y_1=200;x_2=18;y_2=400 \\ \frac{y_2-y_1}{x_2-x_1}=\frac{y-y_1}{x-x_1} \\ \frac{400-200}{18-14}=\frac{y-200}{x-14} \\ \frac{200}{4}=\frac{y-200}{x-14} \\ \frac{50}{1}=\frac{y-200}{x-14} \\ y-200=50(x-14) \\ y-200=50x-700 \\ y=50x-700+200 \\ y=50x-500 \end{gathered}[/tex]

Hence, the equation that best approximate the trend line is y=50x-500

Answers

The probability is 0.236 and the events are not disjoint​ events

Given,

The data;

                                  A       B      C     D

Order accurate      ; 280   245   122  331

Order not accurate; 60     32     12     38

The probability of getting an order that is not accurate or is from Restaurant C

This is illustrative of

P(Not accurate or Restaurant C) (Not accurate or Restaurant C)

The calculation is

P(Not accurate or Restaurant C) is equal to [n(Not accurate) + (Not accurate and Restaurant C) - n(Restaurant C)] /Total

Thus, we have

P(Not accurate or Restaurant C) is calculated as follows: (60 + 32 + 12 + 38 + 122 + 12 - 12)/(280 + 245 + 122 + 331 + 60 + 32 + 12 + 38).

Analyze the difference and the total.

Restaurant C or P(Not accurate) = 264/1120

Assess the quotient.

P(Not accurate or Restaurant C) = 0.236

Last but not least, choosing an incorrect order and choosing an order from Restaurant C are not separate events.

This is because choosing an inaccurate order from restaurant C is a possibility.

i have to find is they similar or not. help im lost

Answers

First we have to find the missing angle on each case.

In the first triangle we have

180°-(28°+80°)=72°

In the second triangle we have

180°-(28°+71°)=81°

Since the values of the angles are not the same for both triangles they are not similar.
