x= 80°

Step-by-step explanation:

An isosceles triangle has two equal sides and two equal angles; so 50° + 50° = 100

then you have to subtract 100° from 180° and you'll get 80°

Step-by-step explanation:

[tex]4(y+1)= \frac{3}{1-y}[/tex]

[tex]4y+4= \frac{3}{1-y}[/tex]

[tex](4y+4)(1-y)= 3[/tex]

[tex]-4y^{2}=3-4[/tex]

[tex]4y^{2}=1[/tex]

[tex]y^{2} = \frac{1}{4}[/tex]

Answer:

2 hours 30 minutes

Step-by-step explanation:

Step one

Given data

The total distance to be covered= 20miles

Priya  runs at a constant speed of 6 miles an hour

Hence Her speed = 6mph

Jada walks at a constant speed of 2 miles an  hour

Hence Her speed = 2mph

let the time taken by them to cover the distance be t

Step two:

from speeed= distance/time

distance= speed*time

so

20=6*t+2*t

20= 6t+2t

20=8t

divide both sides by 8

t= 20/8

t=2.5 hours

That is, it wiil take them 2 hours 30 minutes to meet

The reason is because, the distances covered by them must sum up to 20 miles

Answer:

Extraneous variable.

Step-by-step explanation:

This variable is not seen to work on its own directly in a lot of cases, they are explained to be occurrences or certain factors that are seen to influence the process of the experiment that are not independent variable. In different surveys of studies, it is said to sometimes posses a negative effect on the data consequentially. Many surveys and research has also shown that some of these variables can be controlled while also some of them cannot be controlled.

Answer:

1. -4

2. 6

3. -6

(i hope this is right •_•)

Step-by-step explanation:

First table

When the x coordinate is 0, that point is your y intercept. For the first one, your y intercept is -4.

Second table

For the second one, we need to do a bit of counting. We can see the x coordinates go before and after zero, but the table does not show us 0. So, we're going to have to calculate the slope. Bear with me here, I'm a little tired and this might be rambling ;-;

So, the formula for calculating slope is [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]. I'm going to use those first two points to get my slope. We're going to say the first point is point 1 and the second point is point 2 (genius, i know lol). So, let's substitute in the x and y values.

[tex]\frac{9-12}{-3-(-6)}[/tex]

And simplify...

[tex]\frac{-3}{3}[/tex]

So, your slope is -1. We can use that. We just have to count down.

If the x is -2, the y is 8. If the x is -1, the y is 7. And if the x is 0....(drumroll please) the y is 6! So, your y intercept is 6.

Third table

Now, this table isn't very nice either and doesn't have an x as 0 for us. Hmpf. But we can still do what we did above. I'll just skip the explanation and you can observe my steps.

[tex]\frac{-3-(-5)}{9-3}[/tex]

[tex]\frac{2}{6}[/tex]

[tex]\frac{1}{3}[/tex]

Let's count down....

If x = 3, y = -5

If x = 2, y = -5 1/3

If x = 1, y = -5 2/3

If x = 0, y = -6

Answer:

cubic

Step-by-step explanation:

The degree of the polynomial that best describes the data is quadratic.

Polynomials are kind of algebraic expressions consisting of variables, constants and coefficients along with exponents consisting of finite number of terms.

There are different types of polynomials like linear, quadratic, cubic and so on depending on the highest degree of the variables.

Finite difference method is used to find the degree of the polynomial by finding the difference of the values corresponding to the the values of the independent variable which are equally spaced.

Here, x is the independent variable and the values of x are given.

We have,

x : -3   -1   1   3   5   7

y : 4   6   1   -11   -30   -56

Find the first finite difference of the y values, we get,

x : -3   -1   1   3   5   7

y : 4   6   1   -11   -30   -56

First finite difference : 2   -5   -12   -19   -26

This is not constant.

Second finite difference : -7   -7   -7   -7

Second finite difference is constant.

So this is a polynomial equation of degree 2.

Hence the given polynomial is quadratic.

Answer:

64 degrees

Step-by-step explanation:

The angles of a triangle add up to 180deg. The measure of angle B = 180-74-22 = 84. Since line segment BD bisects angle B, the measure of angle ABD is 1/2 of 84, or 42. Therefore, the measure of angle BDA = 180-74-42 = 64.

Introduction (Kinda)

So you want to write the equation and find the number.

Writing the Equation

Well, the question says "A number s is subtracted from seven. When the result is divided by three, the quotient is two."

If a number s is being subtracted from seven.

7-s

When the result of 7-s is divided by three, the quotient is two. Since your effecting the result of 7-s, you have to put those in parentheses.

(7-s)

Your dividing 7-s by 3.

(7-s) / 3

When you do that, you get 2.

(7-s) / 3 = 2

This is the equation.

Finding the Number

Now you need to solve the equation.

(7-s) / 3 = 2

You need to isolate the s. "Remove" the numbers in opposite PEMDAS order...

Addition and Subtraction

Multiplication and Division

Exponents

Parentheses

7-s is in parentheses.

Divided by 3 is division. So you do that first.

You can multiply by 3 to cancel that out.

(7-s) / 3 × 3 = (7-s)

2 × 3 = 6

7-s = 6

Now that 7-s is on its own side, you can remove the parentheses.

So now to cancel the 7, you subtract 7 from each side (of the equation).

7-s-7 = -s

6-7 = -1

-s = -1

Now to cancel the negative signs, multiply each side by -1.

-s × -1 = s

-1 × -1 = 1

s = 1

Final Answer

The equation is...

(7-s) / 3 = 2

The number is...

Answer:

  AB = 5√2

Step-by-step explanation:

The length of AB is given by the distance formula:

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((4 -(-3))² +(1 -2)²) = √(7² +(-1)²) = √(49 +1) = √50

The length of AB is √50 = 5√2.
