Answer 1

Answer:

16

Step-by-step explanation:

(x + 4)(x + 4) = x² + 8x + 16

Answer 2
16! (x+4)(x+4)
You take half of the middle x value (half of 8x in this case). Half of 8 is 4, square that number (4) and you get 16!

Answer:

[tex] \tan( \theta) = \frac{12}{5} [/tex] = 12:5

Step-by-step explanation:

Jenna’s monthly monetary income is $1,200. Her total spending last month was $1,400. Why would Jenna need a budget?

Answers

Answer:

Because her spending exceeds her monthly income, Jenna needs a budget to avoid spending money she does not have.

Step-by-step explanation:

Jenna need a budget because her monthly income are less than the spending amount.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Jenna’s monthly monetary income is $1,200.

And, Her total spending last month was $1,400.

Here, We have;

⇒ 1200 < 1400

Thus, Jenna need a budget because her monthly income are less than the spending amount.

Therefore, Jenna need a budget because her monthly income are less than the spending amount.

Answer:

  89.0

Step-by-step explanation:

One way to round a number is to add half the place value you're rounding to, then truncate at the desired place value.

Here, we want to round to a tenth (0.1), so we first add half that value:

  88.98 + 0.05 = 89.03

Now, we throw away all digits after the tenths place.

  89.0 . . . . our rounded value

You plan to cut a board into 3 pieces to repair part of a railing. You are going to cut the two ends of the board off into two equal pieces that are 3.6 feet long, if the remaining piece
needs to be 0.82 times longer than the each of the first two cuts what length board should you buy? Round to the nearest tenth.
Type your answer.

Answers

Answer:

13.8 feet long.

Step-by-step explanation:

The end two pieces are 3.6 feet long.

The middle board must be 0.82 longer than the 3.6 feet.

The easy way to do this is to realize that the length of the middle part is 1.82 times the length of each of the end pieces.

1.82 * 3.6 = 6.552 feet long.

So the total length of the board must be

3.6 + 3.6 + 6.552 = 13.752 feet long. (That's a pretty long board).

Rounded it becomes 13.8 feet long.

Answer:

160 degrees

Step-by-step explanation:

starting with the 110 degrees angle. the unnamed angle to the right of the 110 degrees is simply the complement of 110 to 180 degrees = 70 degrees.

then B is actually 180 - 90 - 70 = 20 degrees

and then A is the complementary angle of these 20 degrees to 180 degrees = 160 degrees.

Quadratic Functions and Factoring

Graphs of Quadratic Functions

Parts of a Parabola

The graph of a quadratic function is a parabola, and its parts provide valuable information about the function.

LEARNING OBJECTIVES

Describe the parts and features of parabolas

KEY TAKEAWAYS

Key Points

The graph of a quadratic function is a U-shaped curve called a parabola.

The sign on the coefficient aa of the quadratic function affects whether the graph opens up or down. If a<0a<0, the graph makes a frown (opens down) and if a>0a>0 then the graph makes a smile (opens up).

The extreme point ( maximum or minimum ) of a parabola is called the vertex, and the axis of symmetry is a vertical line that passes through the vertex.

The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function.

Key Terms

vertex: The point at which a parabola changes direction, corresponding to the minimum or maximum value of the quadratic function.

axis of symmetry: A vertical line drawn through the vertex of a parabola around which the parabola is symmetric.

zeros: In a given function, the values of xx at which y=0y=0, also called roots.

Recall that a quadratic function has the form

f(x)=ax2+bx+cf(x)=ax2+bx+c.

where aa, bb, and cc are constants, and a≠0a≠0.

The graph of a quadratic function is a U-shaped curve called a parabola.  This shape is shown below.

Parabola : The graph of a quadratic function is a parabola.

In graphs of quadratic functions, the sign on the coefficient aa affects whether the graph opens up or down. If a<0a<0, the graph makes a frown (opens down) and if a>0a>0 then the graph makes a smile (opens up). This is shown below.

Direction of Parabolas: The sign on the coefficient aa determines the direction of the parabola.

Features of Parabolas

Parabolas have several recognizable features that characterize their shape and placement on the Cartesian plane.

Vertex

One important feature of the parabola is that it has an extreme point, called the vertex. If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value. In either case, the vertex is a turning point on the graph.

Axis of Symmetry

Parabolas also have an axis of symmetry, which is parallel to the y-axis. The axis of symmetry is a vertical line drawn through the vertex.

yy-intercept

The y-intercept is the point at which the parabola crosses the y-axis. There cannot be more than one such point, for the graph of a quadratic function. If there were, the curve would not be a function, as there would be two yy values for one xx value, at zero.

xx-intercepts

The x-intercepts are the points at which the parabola crosses the x-axis. If they exist, the x-intercepts represent the zeros, or roots, of the quadratic function, the values of xx at which y=0y=0. There may be zero, one, or two xx-intercepts. The number of xx-intercepts varies depending upon the location of the graph (see the diagram below).

Possible xx-intercepts: A parabola can have no x-intercepts, one x-intercept, or two x-intercepts

Recall that if the quadratic function is set equal to zero, then the result is a quadratic equation. The solutions to the equation are called the roots of the function. These are the same roots that are observable as the xx-intercepts of the parabola.

Notice that, for parabolas with two xx-intercepts, the vertex always falls between the roots. Due to the fact that parabolas are symmetric, the

Answer:

5x +105=180 (degree )

5x= 180-105 (degree )

5x = 75 (degree )

x = 75/5 (degree )

x = 15 #

therefore, 2x + 3= 2*15 + 3

Find the interquartile range for a data set having the five-number summary: 5.6, 11.1, 19.2, 24.5, 33.3

A. 13.6
B. 27.7
C. 13.4
D. 14.1

Answers

Answer:

C

Step-by-step explanation:

The interquartile range is the difference between the upper quartile Q₃ and the lower quartile Q₁

From the five- number summary , then

Q₃ = 24.5 and Q₁ = 11.1

interquartile range = 24.5 - 11.1 = 13.4 → C

1.A pile of 15 boxes is 3 metres high. What is the depth of each box?

2.An angle measuring 60 degrees is measured as 62 degrees. What is the percentage error correct to 3 significant figures?

solve all for brainiest

Answers

Answer:

#1

The depth of each box:

3 m / 15 = 300 cm / 15 = 20 cm

#2

The error is:

62 - 60 = 2 degrees

The percentage error:

2/60*100% = 3.33% (3 sf)

Answer:

#1

1 m = 100 cm

3 m = 3 × 100 = 300 cm

Depth of one box = 300/15 = 20 cm

#2

Percentage error = Error/Real measure × 100

Round each decimal number to the nearest tenth. Then, select the best estimate for the subtraction equation 1.79 − 0.67 = ___.

Answers

Answer: 1.12

Step-by-step explanation:

Here 1.79 -0.67 = 1.12 ( if we subtract from the large  positive number to a minimum number then it's answer always should be positive value )

Now we are looking for the rounding figure with is very near of it which is 2 decimal or percentage value

For example :

1.444- 0.67 = 0.774 ( Here last digit is 4 so its round will be 0.77)

1.444-0.677 = 0.767 ( Here last digit is 7 so its round will be 0.77)

So we will round the value if it's last digit is greater than or equal to 5 value.
