Answer:

Step-by-step explanation:

The value of the angle x is 85°

The sum of angles of a quadrilateral = 360°

This means that given a quadrilateral with angles, A, B, C, D ;

(A + B + C + D) = 360°

Given the angles of a quadrilateral : (x°, 150°, 77°, 48°)

The value of x will be obtained thus :

(x + 150 + 77 + 48) = 360

150 + 77 + 48 + x = 360

275 + x = 360

x = 360 - 275

x = 85°

Hence, the value of x is 85°

Examples of PEMDAS: When we first learn math, equations only have one operation. We either add, subtract, multiply, or divide. Examples: 2 + 3 = 5 9 - 2 = 7 10 x 3 = 30 81/9 = 9.

Step-by-step explanation:

Answer:

Let’s just hail a taxi.

Step-by-step explanation:

If a rock released with an initial velocity = u

If it falls under gravity 'g' for 't' seconds,

Expression to find the distance covered will be,

[tex]y=ut+\frac{1}{2}t^2[/tex]

If the initial velocity is zero expression for the distance covered will be,

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

Here, g = Gravitational pull Or acceleration due to gravity

A). If the distance covered 'y' = 20 m

     And t = 4 seconds

     By substituting these values in the expression,

     [tex]20=\frac{1}{2}g(4)^2[/tex]

     [tex]20=8g[/tex]

     [tex]g=2.5[/tex] m per sec square

B). Average velocity of a free falling body = [tex]\frac{\text{Initial velocity}+\text{Final velocity}}{2}[/tex]

    Initial velocity of the object = 0

    Final velocity = [tex]g\times t[/tex]

                           = [tex]2.5\times 4[/tex]

                           = [tex]10[/tex] meter per sec.

    Therefore, average velocity = [tex]\frac{0+10}{2}[/tex]

                                                    = [tex]5[/tex] meter per second

C). Since, the rock hits the bottom after [tex]4[/tex] seconds,

     Velocity with which the rock will hit the ground [tex]=gt[/tex]

                                                                                     [tex]=10[/tex] m per sec.

Answer:

A.  y=3x

Step-by-step explanation:

A logarithm is just the opposite function of exponentiation. The common logarithm is called the natural logarithm and the natural logarithm is called the base e logarithm. The value of log, 1257 is 3. The correct option is A.

In mathematics, logarithms are defined as the another way of writing the exponents. A logarithm of a number with a base is equal to another number. A logarithm can be defined as the power to which a number should be raised to obtain some other values.

There are two types of logarithms, they are common and natural logarithm. The common logarithm defines how many times we have to multiply the number 10 to get the required output whereas the natural logarithm shows how many times we have to multiply 'e' to get the required output.

Here the value of log 1257 = 3.099 ≈ 3

Thus the correct option is A.

Step-by-step explanation:

Answer:

4.2

Step-by-step explanation:

d=sqrt[(x1-x2)^2+(y1-y2)^2]

d=sqrt[(5-8)^2+(-5+8)^2]

d=sqrt[(-3)^2+(3)^2]

d=sqrt[9+9]

sqrt18=4.24

The first polynomial is:

-3x³ + 2x – 5

Then we add a polynomial p(x) and we get:

-3x³ + 2x – 5 + p(x) = 4x³ + 7x² – 3

We will find that p(x) = 7x³ + 7x² - 2x + 2

Now let's see how we got it:

Notice that the degree of the polynomial does not change, so p(x) is a polynomial of degree 3.

Then we can write:

p(x) = ax³ + bx² + cx + d

Then we have:

-3x³ + 2x – 5 + ( ax³ + bx² + cx + d) = 4x³ + 7x² – 3

(-3 + a)x³ + bx² + (2 + c)x + (-5 + d) =  4x³ + 7x² – 3

Notice that the above inequality should work for every value of x, so the terms with the same exponent must be equal between them:

(-3 + a)x³ = 4x³

bx² =  7x²

(2 + c)x = 0

(-5 + d) = – 3

Now we can remove the variables in all of these equations to get:

(-3 + a) = 4

b =  7

(2 + c) = 0

(-5 + d) = – 3

Now we can solve all of these and find the coefficients of our polynomial p(x).

-3 + a = 4

a = 4 + 3 = 7

a = 7

b = 7

2 + c = 0

c = -2

-5 + d = -3

d = -3 + 5 = 2

d = 2

Then we have:

p(x) = 7x³ + 7x² - 2x + 2

Answer:

The shirt is $31.50 and the pants are $46.50

Step-by-step explanation:

Let x represent the cost of the pants.

If the shirt is 15 dollars less than the pants, its cost can be represented by x - 15.

Create an equation, and solve for x:

(x) + (x - 15) = 78

2x - 15 = 78

2x = 93

x = 46.5

So, the pants are $46.50.

Subtract 15 from this to find the cost of the shirt:

46.50 - 15

= 31.50

The shirt is $31.50 and the pants are $46.50

Work Shown:

30% of 45 = 0.30*45 = 13.50

You save $13.50 and the sale price is 45 - 13.50 = 31.50 dollars

An alternative is to compute

0.70*45 = 31.50

This works because if you save 30%, then you have to pay the remaining 70%

Answer:

The ratios are not equivalent, so the relationship is not proportional. Therefore, the graph will not be a straight line passing through the origin.

Step-by-step explanation:

Since the ratios of the relationship between length of TV screen and price are not proportional, the graph would not be a proportional graph.

A proportional graph is a straight line graph that passes through the origin (0, 0).

If a relationship has a proportional ratio, then the graph that represents the relationship would be a proportional graph.

Therefore, since the ratios of the relationship between length of TV screen and price are not proportional, the graph would not be a proportional graph.

Here we have a problem of reflections and of how these reflections affect lines. Here we will find that the reflection does not affect the pair of parallel lines, and in the flipped shape we still have a pair of parallel lines.

We can define two parallel lines as two lines that never meet.

And, for a given point (x, y), the simplest reflection across a horizontal line is the reflection across the x-axis (or the line y = 0) as it transforms the point into:

(x, - y)

And all the reflections across horizontal lines will only affect the y-value of the points.

Now, particularly, we have two vertical and parallel lines.

Notice that a vertical line is defined by its x-value, and the transformation we used does not affect the x-value, so a reflection across a horizontal line will not affect a vertical line.

From this, we can conclude that the reflection across a horizontal line will not affect the pair of vertical parallel lines, so at the end, we still have only one pair of parallel lines.
