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.

Answer:. The deposit is £600

Step-by-step explanation:

Multiply £20 times 48 to find the total of the monthly payments.

20 × 48 =£960

Subtract that from the initial cost to find the deposit.

1560 - 960 = 600

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.

(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:

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°

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:

8.16

Step-by-step explanation:

8.16 divided by 0.8 = 10.2

The value of number will be 12.75.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

We have to given that;

Number 10.2 divided by something equals 0.8.

Now,

Let the value of number = x

So, We can formulate;

⇒ 10.2 ÷ x = 0.8

Solve for x as;

⇒ 10.2 / x = 0.8

⇒ x = 10.2 / 0.8

⇒ x = 12.75

Thus, The value of number = 12.75

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.
