Evaluate the following.
1) f(-1)
2)g( -8)
3)f( 1)
4) g(5)
5) f(3)
6) g(-3)

Answers

Step-by-step explanation:

1 .f(x)=[tex]x^{2}[/tex]-x+1

   f(-1)= (-1)-(-1)+1

   f(-1)= 1+1+1

      = 3

3.f(x)=[tex]x^{2}[/tex]-x+1

 f( 1)=(1)-1+1

  f( 1)=1-1+1

        =1

5. f(x)=[tex]x^{2}[/tex]-x+1

    f(3)=[tex](3)^{2}[/tex]-3+1

         = 9-3+1

          =7

2. g(x) = 5 - 3x

 g( -8)=5-3(-8)

g( -8)=5+24

        =29

4.g(x) = 5 - 3x

g(5)=5-3(5)

 g(5)=5-15

       =-10

6.g(x) = 5 - 3x

   g(-3)=5-3(-3)

 g(-3)=5+9

         =14

Answer:

11. x = 5

12. x = 24

Step-by-step explanation:

11.

8x° + 140° = 180°

(Linear pair angles)

8x° = 180° - 140°

8x° = 40°

x ° = 40°/8

x° = 5°

x = 5

12.

2x° + 42° = 90°

(complementary angles)

2x° = 90° - 42°

2x° = 48°

x ° = 48°/2

x° = 24°

x = 24

If the interest 4,000 for 4 years is 1,280 what is the interest rate

Answers

Answer:

For example, with a $4,000 deposit and an annual interest rate of 8 percent, the simple interest after four years would be $1,280. This is calculated by multiplying the principal (P) by the rate (R) and by the rate of time (T): 4,000 x 0.08 x 4 = 1,280.

Explain why dividing each side of \small 3x^2=6x by \small 3x is not a reliable way to solve the equation.

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]3x^2 = 6x[/tex]

Required

Why dividing by [tex]3x[/tex] is not reliable

The reason is that, the given expression is a quadratic equation and as such, it will most likely have two solutions.

So, when the expression is divided by [tex]3x[/tex], the solution will be [tex]x = 2[/tex], leaving out the other possible solution.

The right way is:

[tex]3x^2 = 6x[/tex]

Subtract 6x from both sides

[tex]3x^2 - 6x = 6x - 6x[/tex]

[tex]3x^2 - 6x = 0[/tex]

Factorize

[tex]3x(x - 2) = 0[/tex]

Split

[tex]3x = 0\ or\ x - 2 = 0[/tex]

Solve for x in both cases:

[tex]x = 0\ or\ x = 2[/tex]

Dora has three candles, which will burn for 3, 4 and 5 hours, respectively. If she wants to keep two candles burning at all times, what is the greatest number of hours she can burn the candles? (Dora has a clock that she can use to time the candles.)

Answers

Answer:

3 hrs 38.2 min, Candle 2 will be three times the length of candle 1

Step-by-step explanation:

If Dora burns candles that burn for 4 and 5 hours they burn for 9 hours combined one after another.

What are permutation and combination?

In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.

here,
Dora has three candles, which will burn for 3, 4, and 5 hours,
The combination of the hours of burning,
3 + 4 = 7 hours
4 + 5 = 9 hours
3 + 5 = 8 hours

Thus, if Dora burns candles that burn for 4 and 5 hours they burn for 9 hours combined one after another.

Urban rail systems have been proposed to alleviate traffic congestion, but results in many cities have been cited as evidence that this approach to traffic management is ineffective. For example, a U.S. city that opened three urban rail branches experienced a net decline of 3,100 urban rail commuters during a period when employment increased by 96,000. Officials who favor urban rail systems as a solution to traffic congestion have attempted to counter this argument by noting that commuting trips in that city represent just 20 percent of urban travel.
The response of the officials to the claim that urban rail systems are ineffective is most vulnerable to criticism on the grounds that it
A) presents no evidence to show that the statistics are incorrect
B) relies solely on general data about U.S. cities rather than data about the city in question
C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion
D) fails to show that the decline in the number of urban rail commuters in one U.S. city is typical of U.S. cities generally
E) provides no statistics on the use of urban rail systems by passengers other than commuters

Answers

Answer:

C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion

Step-by-step explanation:

The correct option is - C) fails to consider that commuting trips may cause significantly more than 20 percent of the traffic congestion

Reason -

Option A is incorrect because the statistics can not be incorrect.

Option B is incorrect because they are not talking about the city.

Option C is correct because Urban rail reduces congestion.

Option D is incorrect because the opposers cited the example of one city and the supporters are presenting evidence in the case of that city itself.

Option E is incorrect because they are providing an explanation for why the commuters data given by opposers is not relevant. The opposers talked about commuters.

Izzy is saving up for a road trip that is happening6 weeks from today. At this moment, Izzy has $90 in her savings account. She plans on saving $25 a week.

Answers

Answer:

$210

Step-by-step explanation:

Given data

time = 6 weeks

initial amount= $90

saving per week = $25

Hence the expression for the total savings after the 6 weeks is given as

y= mx+c

where

m= $25

x= 6 weeks

c= $90

substitute

y=25*6+90

y= 150+60

y= $210

Hence the total amount after 6 weeks is $210
