Answers

Answer 1

Answer:

...

Step-by-step explanation:

Answer 2

Answer:

so you have a 40% chance or 2/5 chance

Step-by-step explanation:

30 numbers in total

12 are less than 13

so you have a 12/30

simplify

2/5 = 0.4 or 40%

Band A: charges $600 to play for the evening

Band B: Charges $350 plus $1.25 per student



After how many students would it be better to hire Band A?

Answer:

After 200 students, it would better to hire Band A

1.25x = 250

x = 200

at 200 students the cost is the same for Band A and Band B

at 201 students Band A will be cheaper then Band B

hi someone help with these two questions. Thanks

Answers

Answer:

1). Option (d)

2). Options (a), (b) and (d)

Step-by-step explanation:

Question 1

a). [tex]3x^5-6x^3+9x-12x^{-1}[/tex]

   Any expression with negative exponent is not a polynomial.

b). [tex]4\sqrt{x}+5[/tex]

   Any expression having variable with square root is not a polynomial.

c). [tex]\frac{4x+5}{3x-1}[/tex]

   Any expression having variables in the form of a fraction is not a polynomial.

d). [tex]-\frac{3}{2}x^{12}-7x^5+\frac{2}{3}x-10[/tex]

   It's a polynomial.

e). [tex]-5x^{\frac{3}{2}}-7x^2+6[/tex]

   Expressions having variables with square root are not the polynomial.

Therefore, Option (d) is a polynomial.

Question 2.

P(x) = (2x + 1)(5x³ - 8x + 4)

      = 2x(5x³ - 8x + 4) + 1(5x³ - 8x + 4)

      = 10x⁴ - 16x² + 8x + 5x³ - 8x + 4

      = 10x⁴ - 5x³ - 16x²+ 4

a). Degree of polynomial = 4

   True

b). P(0) = 10(0) - 5(0) - 16(0) + 4

           = 4

    True

c). P(-1) = 10(-1)⁴ - 5(-1)³ - 16(-1)² + 4

           = 10 + 5 - 16 + 4

           = 3

    False

d). Coefficient of x₂ is -16.      

    True

e). Coefficient of x is -16

    False

Therefore, Options (a), (b) and (d) are correct.

FYI you just need to use the Pythagorean theorem to solve this

A^2 + B^2 = C^2

The Frostburg-Truth bus travels from Frostburg Mall through the city's center to Sojourner Truth Park. The mall is 4 miles east and 5 miles north of the city's center. Truth Park is 4 miles west and 2 miles south of the city's center. How far is it from Truth Park to the mall to the nearest tenth of a mile? A-10.6 B-4.5 C-3 D-6.4

Answers

Answer:

10.9 miles

Step-by-step explanation:

distance of the park to the mall = distance of the mall from the city centre + distance of the park from the city centre

this question would be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypothenuse

distance of the mall from the city centre = 5² + 4²

25 + 16 = 41

√41 = 6.403124 miles

distance of the park from the city centre = 4² + 2²

16 + 4 = 20

√20 = 4.472136 miles

Total distance =  6.403124 miles + 4.472136 miles = 10.875260

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

the hundredth is 7. it is greater than 5. So, 1 is added to the tenth term. this gives 10.9 miles

Answer:

[tex]Rate = 6[/tex]

[tex]Rate = 10[/tex]

[tex]Rate = 18[/tex]

[tex]Rate = 162[/tex]

Step-by-step explanation:

Given

See attachment for table

Solving (a): Rate of change between 2nd and 3rd point on A

The rate of change is calculated as:

[tex]Rate = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

In table A, the 2nd and 3rd point is:

[tex](x_1,y_1) =(1,7)[/tex]

[tex](x_2,y_2) =(2,13)[/tex]

So, the average rate of change is:

[tex]Rate = \frac{13 - 7}{2 - 1}[/tex]

[tex]Rate = \frac{6}{1}[/tex]

[tex]Rate = 6[/tex]

Solving (b): Rate of change between 3rd and 4th point on A

In table A, the 3rd and 4th point is:

[tex](x_1,y_1) =(2,13)[/tex]

[tex](x_2,y_2) =(3,23)[/tex]

So, the average rate of change is:

[tex]Rate = \frac{23 - 13}{3 - 2}[/tex]

[tex]Rate = \frac{10}{1}[/tex]

[tex]Rate = 10[/tex]

Solving (c): Rate of change between 2nd and 3rd point on B

In table B, the 2nd and 3rd point is:

[tex](x_1,y_1) =(2,11)[/tex]

[tex](x_2,y_2) =(3,29)[/tex]

So, the average rate of change is:

[tex]Rate = \frac{29 - 11}{3 - 2}[/tex]

[tex]Rate = \frac{18}{1}[/tex]

[tex]Rate = 18[/tex]

Solving (d): Rate of change between 4th and 5th point on B

In table B, the 4th and 5th point is:

[tex](x_1,y_1) =(4,83)[/tex]

[tex](x_2,y_2) =(5,245)[/tex]

So, the average rate of change is:

[tex]Rate = \frac{245 - 83}{5 - 4}[/tex]

[tex]Rate = \frac{162}{1}[/tex]

[tex]Rate = 162[/tex]

Answers

Answer:

Step-by-step explanation:

Question

Find the perimeter of a triangle with vertices A(2,5) B(2,-2) C(5,-2). Round your answer to the nearest tenth and show your work.​

perimeter of a triangle = AB+AC+BC

Using the distance formula

AB = sqrt(-2-5)²+(2-2)²

AB = sqrt(-7)²

AB =sqrt(49)

AB =7

BC = sqrt(-2+2)²+(2-5)²

BC = sqrt(0+3²)

BC =sqrt(9)

BC =3

AC= sqrt(-2-5)²+(2-5)²

AC= sqrt(-7)²+3²

AC =sqrt(49+9)

AC =sqrt58

Perimeter = 10+sqrt58

We can just factor this to get (x - 4) (x + 2). In the 3rd question, possible factors for the coefficient are 1, 2, -1, -2. Possible factors for the constant are 1, 7, -1, -7. Now, we can try out all of them. The possible factors are 1, 7, -1, -7, 2, 14, -2, -14.
