Part A: The average rate of change between the 2nd and 3rd point is Select a Value Part A: The average rate of change between the 3rd and 4th point is Select a Value Part B: The average rate of change between the 2nd and 3rd point is Select a Value Part B: The average rate of change between the 4th and 5th point is Select a Value
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]

hi someone help with these two questions. Thanks
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.
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.
Edit: Nvm I got it:)
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

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
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
