Step-by-step explanation:

Answer:

X would equal 1

Answer:

Answer : d. minimum (-1,3)

The vertex form of quadratic function is

, where (h,k) is the vertex

To get vertex form we apply completing the square method

To apply completing the square method , there should be only x^2

So we factor out 5 from from first two terms

Now we take the number before x (coefficient of x) and divide by 2

=1

Now square it

Add and subtract 1 inside the parenthesis

Now we take out -1 by multiplying 5

Now we factor x^2 +2x+1 as (x+1)(x+1)

h=-1  and k=3

So vertex is (-1,3)

When the value of 'a' is negative , then it is a maximum

When the value of 'a' is positive , then it is a minimum

is in the form of  

The value of a is 5

5 is positive so it is a minimum

f(x) is minimum at point (-1,3)

Answer:

Total surface area = 485.4594 in

Step-by-step explanation:

Triangles area:

[tex]a = \frac{bh}{2} \\ h = 9 \cos(45) \\ h = 9.363961 \\ a = \frac{15 \times 9.363961}{2} \\ a = 47.7297[/tex]

rectangles area:

[tex]a = 10 \times 12 \\ a = 120[/tex]

and

[tex]a = 15 \times 10 \\ a = 150[/tex]

Total surface area:

[tex]a = 2(47.7297) + 2(120) + 150 \\ a = 95.4594 + 240 + 150 \\ a = 485.4594[/tex]

Option "D" is the correct answer.

Answer:

The average rate of change of the function is 22.

Step-by-step explanation:

The given function is :

[tex]f(x)=x^4-5x[/tex]

We need to find the average rate of change of the function on the closed interval (0, 3).

The average rate of change of a function in interval (a,b) is given by :

[tex]R=\dfrac{f(b)-f(a)}{b-a}[/tex]

Here, a = 0 and b = 3

[tex]R=\dfrac{(3^4-5(3))-(0^4-5(0))}{3-0}\\\\=\dfrac{66}{3}\\\\=22[/tex]

So, the average rate of change of the function is 22.

Answer:

22

Step-by-step explanation:

(f(3)-f(0))/3

=66/3

=22

Answer:

90

Step-by-step explanation:

Answer:

Angles 1 and 5 are corresponding angles.

Step-by-step explanation:

These are the different types of angles formed by a transversal:

1. Corresponding angles are angles that lie on the same side of the transversal line. Angles 1, 3, 5, 6, 9, and 11 are corresponding angles because they are all on the left side of the transversal (the line that cuts through the other lines). Angles 2, 4, 6, 8, 10, and 12 are corresponding angles because they are all on the right side of the transversal.

2. Alternate interior angles are angles that are nonadjacent angles that lie on opposite sides of the transversal and in between the horizontal lines. Here the alternate interior angles are 3 and 6, 4 and 5, 7 and 10, and 8 and 9.

3. Alternate exterior angles are those that are nonadjacent and lie on the outside of the horizontal lines. In this diagram, angles 1 and 12 and angles 2 and 11 are alternate exterior.

4. Same-side interior angles are angles that lie on the same side of the transversal and in between the horizontal lines. The same-side interior angles in this diagram are angles 3 and 5, 7 and 9, 4 and 6, and 8 and 10.

Answer:

16.67

Step-by-step explanation:

Solution for 90 is what percent of 540:

90:540*100 =

(90*100):540 =

9000:540 = 16.67

Answer:

16.67

Step-by-step explanation:

To find percentage, we need to find an equivalent fraction with denominator 100. Multiply both numerator & denominator by 100

94/ 540 × 100/ 100

= ( 90 × 100/ 540 ) × 1/ 100

= 16.67/ 100

the answer is 16.67%

Answer:

9 trips

Step-by-step explanation:

Given that :

Total Distance walked is dependent on the total number of trips made to school ;

d = t + 3 ;

d = total distance in kilometers ; t = number of trips made ;

Number of trips required to walk a total of 12 kilometers ;

d = 12

Putting d = 12 in the equation ;

12 = t + 3

12 - 3 = t

9 = t

Hence, Number of trips made = 9

Step-by-step explanation:

Answer:

2 possible full shifts

Step-by-step explanation:

Given

Total number of hours per week= 24hours

Number of hours worked so far= 7 hours

Number of hours remaining =24-7 = 17hours

If each shift remaining are 6hours long then

1shift = 6hrs

x = 17 hours

Cross multiply

6x = 17

x = 17/6

x = 2.83

Hence she can only work 2 possible full shifts

Answer:

Current insurance cost = [tex]685.43[/tex] $

Step-by-step explanation:

Given

Reduced Amount = [tex]4.1\%\:\times\:714.73[/tex]

                              [tex]=\left(\frac{4.1}{100}\right)\left(714.73\right)[/tex]

                              [tex]=\frac{41\times \:714.73}{1000}[/tex]

                               [tex]=29.30[/tex] $

Current Insurance cost = [tex]714.73 - 29.30[/tex]

                                       = [tex]685.43[/tex] $

Thus,

Current insurance cost = [tex]685.43[/tex] $

Answer:

The points are (-1, 1), (2, 7), (1, -1), (3, 0)

Step-by-step explanation:

Let us solve the question

∵ f(x) = y

∴ The coordinates of the point are (x, y)

→ Let us use this fact to find the coordinates of each point

∵ f(-1) = 1

∴ x = -1 and y = 1

∴ The coordinates of the point are (-1, 1)

∵ f(2) = 7

∴ x = 2 and y = 7

∴ The coordinates of the point are (2, 7)

∵ f(1) = -1

∴ x = 1 and y = -1

∴ The coordinates of the point are (1, -1)

∵ f(3) = 0

∴ x = 3 and y = 0

∴ The coordinates of the point are (3, 0)

The graph is attached down

Answer:

The Y intercept is 9, and The Slope is 7x

Answer:

slope: 7 (or 7/1)

y int: 9

Step-by-step explanation:

Slope intercept formula is y=mx+b

(m) is slope

(b) is y intercept

so in

y=9+7x

we can flip the numbers around

y=7x+9

so 7 is our slope and 9 is the y intercept

The range of the graphed function is -4≤y≤8.

Option (A) is correct.

To find the range of the graphed function.

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given that:

It is given that the graph shows parabolic.

The "range" is the vertical extent of the graph.

The range of a function refers to the values of y for which x is defined.

The least value of y from the graph is -4.

The reason is that each box is 2 units, therefore tracing down to the third box on the y-axis gives -4.

Similarly the highest value is 9..

So, the range of the graphed function is -4≤y≤9.
