Answer:

  2

Step-by-step explanation:

You need the smallest positive integer for which f(x) > 0.

  f(1) = 3 -4 -3 -1 = -5

  f(2) = ((3·2 -4)2 -3)2 -1 = (4 -3)2 -1 = 1

x = 2 is the smallest integer for which f(x) > 0.

Answer:

Diana has 14 dimes and 12 nickels

Step-by-step explanation:

Create a system of equations, where d is the number of dimes and n is the number of nickels:

d + n = 26

0.1d + 0.05n = 2

Solve by elimination by multiplying the top equation by -0.1:

-0.1d - 0.1n = -2.6

0.1d + 0.05n = 2

Add these together, then solve for n:

-0.05n = -0.6

n = 12

So, she has 12 nickels. To find the number of dimes, subtract 12 from 26, since there were 26 coins in total and we found that she had 12 nickels.

26 - 12

= 14

So, Diana has 14 dimes and 12 nickels

Question:

Analyze the following budget, with an income of $600, to determine how much can be spent on food for the month.

Cell Phone $65

Food $___

Entertainment $95

College Savings $200

Car Expenses - Gas, Insurance $160

Answer:

[tex]Food = \$80[/tex]

Step-by-step explanation:

Given

[tex]Income = \$600[/tex]

Required

How much should be spent on food

This is calculated as:

[tex]Income = Food + Other\ budgets[/tex]

Where:

[tex]Other\ budgets = Phone + Ent + College + Car, Gas[/tex]

[tex]Other\ budgets = \$65 + \$95 + \$200 + \$160[/tex]

[tex]Other\ budgets = \$520[/tex]

So, we have:

[tex]\$600 = Food + \$520[/tex]

[tex]Food = \$600 - \$520[/tex]

[tex]Food = \$80[/tex]

Answer:

C $80 can be spent on food.

Given:

Two trail maps:

Trail on the first map = 8 cm

Trail on the second map = 6 cm

Scale on first map = 1 cm : 2 km

A) What is the scale factor from the map to the actual trail?

For the first map, the scale factor is 1 cm: 2km. Therefore the actual trail is 8 centimeters * 2 kilometers = 16 km.

The scale factor of the second map is 16 km / 6 cm = 2.67 km : 1 cm

B) The length of the actual trail is 16 kilometers.

Step-by-step explanation:

In this exercise we have to use the knowledge of distance to calculate the value of the length, like this:

A) 1 cm

B) 16K

some of the information given in the statement was from:

Trail on the first map = 8 cmTrail on the second map = 6 cmScale on first map = 1 cm : 2 km

A) So to calculate the scale, you will need:

[tex]1 cm: 2km\\8 centimeters * 2 kilometers = 16 km\\16 km / 6 cm = 2.67 km : 1 cm[/tex]

B) So from the previous calculations we find the value of the length which is 16 kilometers.

The system of equations will have no real solutions for c = -5, d = 4, i.e. option B.

What is system of equations?

System of equations is a finite set of equations for which common solutions are sought.

We have,

y = cx² + d     .....(i)

And,

2y = 10

⇒

y = 5     .....(ii)

So,

Now,

Comparing equation (i) and (ii),

We get,

cx² + d = 5

Now,

According to the question,

For,

c = -6, and d = 6

i.e.

cx² + d = 5

-6x² +6 = 5

We get,

-6x² = -1

i.e. [tex]x^2 = \frac{1}{6}[/tex]

That means equation have real solution.

Now,

For,

c = -5, and d = 4

i.e.

cx² + d = 5

-5x² + 4 = 5

We get,

-5x² = 1

i.e. [tex]x^2 = \frac{1}{-5}[/tex]

So, For these values of c and d, equation will not have any real solution, because square root can not be negative.

Hence, we can say that the system of equations will have no real solutions for c = -5, d = 4, i.e. option B.

Answer:

  a) line: y = x - 11

  b) k = -9

  c) AP = BP = √74

Step-by-step explanation:

There are four (4) formulas that are needed for solving this problem.

  m = (y2 -y1)/(x2 -x1) . . . . . . slope of a line between points (x1, y1) and (x2, y2)

  M = ((x1 +x2)/2, (y1 +y2)/2) . . . . midpoint of the segment between the points

  y -y1 = m(x -x1) . . . . . point-slope equation of a line given point and slope

  d = √((x2 -x1)² +(y2 -y1)²) . . . . distance between two points

In addition, you need to know that perpendicular lines have opposite reciprocal slopes.

__

The perpendicular bisector of a segment between two points will be a line with a slope that is the opposite reciprocal of the slope of the segment. That line will go through the midpoint of the segment.

a) The slope of the segment between A(7, -2) and B(9, -4) is ...

  m = (-4-(-2))/(9-7) = -2/2 = -1

The midpoint of AB is ...

  M = ((7+9)/2, (-2-4)/2) = (8, -3)

The opposite reciprocal of the slope of AB is ...

  m = -1/(-1) = 1

Then the point-slope equation of the perpendicular bisector is the line with slope 1 through the point (8, -3):

  y -(-3) = 1(x -8)

  y = x -11

__

b) Point P on the line has x-value of 2, so the y-value will be ...

  k = 2 -11 = -9

Point P has coordinates (2, -9).

__

c) The length of segment AP is given by the distance formula:

  d = √((2 -7)² +(-9-(-2))²) = √((-5)² +(-7)²) = √74

The length of segment BP is likewise given by the distance formula:

  d = √((2 -9)² +(-9 -(-4))²) = √((-7)² +(-5)²) = √74

AP = √74 = BP   ⇒   AP ≅ BP
