The given function is

All quadratic functions represent a parabola. If the quadratic term is positive, the parabola opens up, if the quadratic term is negative, the parabola opens down.

In this case, we observe a positive quadratic term, so the parabola opens up, which means the function has a minimum.

To find the minimum of the function, we need to find its vertex (h,k), where

a = 1 and b = -2.

Then, evaluate the function to find k.

The k-coordinate of the vertex refers to the minimum value.

Therefore, the answer is -6.

We have that the distributive property states that the multiplication is done for all the terms inside the parenthesis. Then we have:

Since

3 · 28 = 84

and

3 · □ = 93

Since 3 · 31 = 93, then

□ = 31

Answer:

- 28

Step-by-step explanation:

-2 + { -3 - [ 7 + 4·( -2 + 5 ) ] } - 4

1)

( -2 + 5 ) = 3

2)

[ 7 + 4·3  ]  = [ 7 + 12 ] = 19

3)

{ -3 - 19 } = - 22

4)

- 2 + ( -22) - 4 = -2 - 22 - 4 = - 28

The y-intercept of an equation is where its graph intersects the y-axis - this happens at x = 0; therefore, putting in x =0 should give us the y-intercept.

Putting in x = 0 gives

Hence, the y-intercept is y = -4.

The x-intercept of an equation is where its graph intersects the x-axis - this happens where y = 0; therefore, the x-intercept is found by putting in y =0:

Hence, the x-intercept is x = 2.

In a fraction, we have that the top number is the numerator and the bottom number is the denominator.

Also, in a mixed number, we have a whole number together with a fraction, but the denominator still is the bottom number of the fraction

So the statement of the question is FALSE.

To solve this problem, we must use the formula:

Where:

• A = final amount = ?,

• P = starting amount = $400.00,

• r = interest rate in decimals = 4% = 0.04,

• n = number of times per year that the interest is compounded = 1 (because interest is compounded annually),

• t = time in years = 2.

Replacing the data of the problem in the equation above, we get:

ANSWER:

Answer:

[tex]\{ y\; |\; 0 \leq y < 9 \}[/tex]

Step-by-step explanation:

The range of a function is the set of all possible output values (y-values).

From inspection of the given graph:

As there is an open circle where y = 9, this means the value is not included in the range.

Therefore, the range of the function is:

[tex]\{ y\; |\; 0 \leq y < 9 \}[/tex]

Total number of drinks sold = 45 + 31 + 47 +27 = 150

Lemonade and ice tea = 45 +27 = 72

Divide the number of lemonades and ice tea drinks sold, by the total number of drinks sold.

72 / 150 = 0.48

Multiply by 100

0.48 x 100 = 48% (option A)

In order to determine the time for research, calculate one quarter of the time spend in the project of the company.

Express the time for the project as a normal fraction, as follow:

5 1/3 = 5/1 + 1/3 = (15 + 1)/3 = 16/3

Next, multiply 1/4 (one quarter) by the previous fraction 16/3:

(1/4)·(16/3) = 16/12

simplify the previous fraction:

16/12 = 4/3

as a mixed number the previous result is:

EXPLANATION

A special form of average is the Geometric Mean, where we sum the numbers together and then take a square root (for two numbers), cube root (for three numbers), etc.

The geometric mean between 10 and 25 is equal to:

sqrt(10*25)= 15.81

Answer is 5*sqrt(10) or 15.81

Answer: They are both equal

1 meter = 10 decimeter

We need to convert 100 decimeters to meters

1 meter = 10 decimeter

x meter = 100 decimeter

Cross multiply

x * 10 = 1 x 100

10x = 100

Divide both sides by 10

10x/10 = 100/10

x = 10 meters

Hence, 10 meters is equal to 100 decimeter

Answer: They are both equal

The value of n will be equal to -7/2 or [tex]-4\frac{1}{2}[/tex].

This question can be solved using the Laws of exponents. We have the expression 1/8 ÷ √2 = 2ⁿ. We can rearrange this expression as follows

1/(8×√2) = 2ⁿ

We can also write this as

1/(2³·2^1/2) = 2ⁿ

From laws of exponents if bases are same then the powers get add up that is

1/(2^7/2) = 2ⁿ

2^-7/2 = 2ⁿ

From laws of exponents, we compare that the bases are same so the powers will also be same. So, we find that n = -7/2 which can be written in improper fraction as [tex]-4\frac{1}{2}[/tex].

Answer:

[tex]3\, x + (-1)\, y = 1[/tex].

Step-by-step explanation:

Both the slope of this line and the coordinates of a point on this line are given. Therefore, start by finding the point-slope equation of this line: if the slope of a line in a plane is [tex]m[/tex], and this line goes through a point at [tex](x_{0},\, y_{0})[/tex], the point-slope equation of this line will be [tex](y - y_{0}) = m\, (x - x_{0})[/tex].

The slope of the line in this question is [tex]m = 3[/tex]. It is given that this line goes through the point [tex](2,\, 5)[/tex], where [tex]x_{0} = 2[/tex] and [tex]y_{0} = 5[/tex]. Substitute in these values to find the point-slope equation of this line:

[tex](y - y_{0}) = m\, (x - x_{0})[/tex].

[tex](y - 5) = 3\, (x - 2)[/tex].

Rewrite this point-slope equation in the requested format:

[tex]y - 5 = 3\, x - 6[/tex].

[tex]3\, x - 6 = y - 5[/tex].

[tex]3\, x = y + 1[/tex].

[tex]3\, x - y = 1[/tex].

[tex]3\, x + (-1)\, y = 1[/tex].

The height of the object based on the information is 1963 feet.

It should be noted that a function is important to show the relationship between the variables given in the data.

In this case, the function given for the height of the object is given as:

h = 16t² + 1899

where t = time

When the time is 2 seconds, the height will be:

h = 16t² + 1899

h = 16(2)² + 1899

h = 64 + 1899

h = 1963

The height is 1963 feet.

The relationship between x and y points is a linear relationship of the form:

y = mx + b

where m is the slope of the line, and b is the coordinate y for the y-intercept.

Now, by definition, we have that the slope of the line is given by:

where (X1,Y1) and (X2,Y2) are given points on the graph.

In our case, we can take

(X1, Y1) =(2,-1)

(X2,Y2) = (3,2)

then, te slope of the line would be:

then m = 3 and the new equation for our graph would be:

y = 3x+b

Now, to find b, take any point (x,y) on the graph. In this case, for example

(x,y) = (3,2) and replace this point in the above equation:

2= 3(3) + b

solve for b:

2-9 = b

then b = -7 and we can conclude that the equation for our graph is:

y = 3x-7
