Answer:

1. 5√7

2. (√15)/6

Step-by-step explanation:

1. √175

= √(25) * √(7)

= 5√7

2. √(5/12)

= (√5)/(√12)

= (√5)/(√(4) * √(3))

= (√5)/(2√3)

Radicals can't be in the denominator:

(√5)/(2√3)

(√5 * 2√3)/(2√3 * 2√3)

The slope is -3/(2+3a)² and the equation of the line is y - 1/8 = [-3/(2+3a)²](x - 2).

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

​f(x) = 1 / 2+3x and point P = (2 , 1/8)

f(x+h) = 1/(2 + 3a + 3h)

f(a) = 1/(2 + 3a)

m(tan) = [1/(2 + 3a + 3h) - 1/(2 + 3a)]/h

After simplifying:

m(tan) = -3/[(2+3a)(2+3a+3h)]

h = 0

m(tan) = -3/(2+3a)²

The equation of the line:

y - 1/8 = [-3/(2+3a)²](x - 2)

Thus, the slope is -3/(2+3a)² and the equation of the line is y - 1/8 = [-3/(2+3a)²](x - 2).

A linear function will have the form f(x) = mx + b.

f(0)=7 means the point (0,7) is on this line.

f(3)=1 means the point (3,1) is on the line as well.

Using those two points, we can find the slope:

   m = (1-7)/(3-0) = -6/3 = -2

Since we were given f(0)=7, we also know the y-intercept.

So our function is f(x) = -2x+7

The standard form of the quadratic function y=ax² + bx + c = a (x - h)² + k

By definition, quadratic function is a function in the form f(x) = ax² + bx + c, where a, b, and c are numbers with a not equal to zero.

ax² + bx + c = a (x² - 2xh + h²) + kax² + bx + c

= ax² - 2ah x + (ah² + k)

Comparing the coefficients of x on both sides,b = -2ah ⇒ h = -b/2a .............................................(i)

Comparing the constants on both sides,c = ah² + kc = a (-b/2a)² + k (From (1))

c = b²/(4a) + kk = c - (b²/4a)k = (4ac - b²) / (4a)

Therefore, we can use the formulas h = -b/2a and k = (4ac - b²) / (4a) to convert the standard form to its vertex form.

the vertex form of the parabola is  y = a (x - h)² + k

The standard form of the parabola is y = ax² + bx + c

The standard form of the quadratic function y=ax²+bx+c is x=-b± [tex]\frac{\sqrt{b^{2}- } 4ac}{2a}[/tex]

3.  Neither.

4.  121,800

Step-by-step explanation:

A recursive rule for a sequence allows you to find the nth term of the sequence provided you know the value of the previous term in the sequence.

Given recursive rule:

[tex]\begin{cases}s_n=s_{n-2} \cdot (s_{n-1}-1)\\s_1=2\\s_2=3\end{cases}[/tex]

Therefore, the first 9 terms of the sequence are:

[tex]s_1=2[/tex]

[tex]s_2=3[/tex]

[tex]\begin{aligned}s_3&=s_{3-2} \cdot (s_{3-1}-1)\\&=s_{1} \cdot (s_{2}-1)\\&=2 \cdot (3-1)\\&=2 \cdot 2\\&=4 \end{aligned}[/tex]

[tex]\begin{aligned}s_4&=s_{4-2} \cdot (s_{4-1}-1)\\&=s_{2} \cdot (s_{3}-1)\\&=3 \cdot (4-1)\\&=3 \cdot 3\\&=9 \end{aligned}[/tex]

[tex]\begin{aligned}s_5&=s_{5-2} \cdot (s_{5-1}-1)\\&=s_{3} \cdot (s_{4}-1)\\&=4 \cdot (9-1)\\&=4 \cdot 8\\&=32 \end{aligned}[/tex]

[tex]\begin{aligned}s_6&=s_{6-2} \cdot (s_{6-1}-1)\\&=s_{4} \cdot (s_{5}-1)\\&=9 \cdot (32-1)\\&=9 \cdot 31\\&=279\end{aligned}[/tex]

[tex]\begin{aligned}s_7&=s_{7-2} \cdot (s_{7-1}-1)\\&=s_{5} \cdot (s_{6}-1)\\&=32 \cdot (279-1)\\&=32 \cdot 278\\&=8896\end{aligned}[/tex]

[tex]\begin{aligned}s_8&=s_{8-2} \cdot (s_{8-1}-1)\\&=s_{6} \cdot (s_{5}-1)\\&=279 \cdot (8896-1)\\&=279\cdot 8895\\&=2481705\end{aligned}[/tex]

[tex]\begin{aligned}s_9&=s_{9-2} \cdot (s_{9-1}-1)\\&=s_{7} \cdot (s_{8}-1)\\&=8896\cdot (2481705-1)\\&=8896\cdot 2481704\\&=22077238784\end{aligned}[/tex]

Given series:

[tex]\displaystyle \sum^8_{k=1} s_k[/tex]

The sum notation asks to find the sum of the first 8 terms of the sequence from question 1.

Therefore:

[tex]\begin{aligned}\displaystyle \sum^8_{k=1} s_k&=s_1+s_2+s_3+s_4+s_5+s_6+s_7+s_8\\&=2+3+4+9+32+279+8896+2481705\\&=2490930\end{aligned}[/tex]

If a sequence is arithmetic, the difference between consecutive terms is the same (this is called the common difference).

If a sequence is geometric, the ratio between consecutive terms is the same (this is called the common ratio).

As the difference between consecutive terms it not the same, the sequence is not arithmetic.

As the ratio between consecutive terms is not the same, the sequence is not geometric.

Therefore, the sequence is neither arithmetic nor geometric.

[tex]\boxed{\begin{minipage}{7.3 cm}\underline{Sum of the first $n$ terms of an arithmetic series}\\\\$S_n=\dfrac{1}{2}n[2a+(n-1)d]$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\ \phantom{ww}$\bullet$ $d$ is the common difference.\\ \phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]

Given arithmetic sequence:

Therefore:

To find the sum of the first 200 terms, substitute the found values of a and d into the formula along with n = 200:

[tex]\begin{aligned}S_{200}&=\dfrac{1}{2}(200)[2(12)+(200-1)(6)]\\&=100[24+(199)(6)]\\&=100[24+1194]\\&=100[1218]\\&=121800\end{aligned}[/tex]

The third term from the sequence should be 48 so that (a) the next term is 147 (b) the rule to find the nth term is 3×n² and (c) the 20th term is 1200.

From the question, 3, 12, 27, 64, 75, 108 the third term 64 is supposed to be 48. hence the terms are derived as follows:

1st term; 3 × 1² = 3

2nd term;3 × 2² = 12

3rd term; 3 × 3² = 27

4th term; 3 × 4² = 48

5th term; 3 × 5² = 75

6th term; 3 × 6² = 108

Therefore, the next term which the 7th term is 3 × 7² = 147, the rule for the sequence is 3×n² and the 20th term is 3 × 20² = 1200.

Using the two points on the graph, Sandra can prove that her speed was constant using: Slope (m) = (18 - 6) / (3 - 1).

The slope of a graph is the ratio of the vertical distance along the line to the horizontal distance across the line, which is given as, m = change in y / change in x.

For a proportional graph, the slope is always constant, for whichever points we choose to use on the line.

Given two points on the line that Sandra chose, (3, 18) and (1, 6), therefore:

Slope (m) = change in y / change in x

Slope (m) = (18 - 6) / (3 - 1)

Slope (m) = 12/2

There are 9216 more white squares than black squares in the 47th term with it's an odd number of 97

The terms are generated with the square of odd numbers with the black squares being the addition of the odd number and one subtracted from it.

For the 47th term:

Given that the first term is consists of 25 squares with 9 black and 16 white squares

first term has odd number 5

the square of 5; 5² = 25

black squares = 5 + (5-1) = 9

white squares = 25 - 9 = 16

Therefore, for the 47th term:

47th term has odd number 97

the square of 97; 97² = 9409

black squares = 97 + (97-1) = 193

white squares = 9409 - 193 = 9216

Hence, the 47th term has an odd number 97 with 9216 more black squares than the white squares,

The corresponding values of F1 and F2 in the ordered pairs are 77 degrees Fahrenheit and -22 degrees Fahrenheit

Given: the equation F=9/5C+32 and ordered pairs: (25, F1), (−30, F2)

In order to convert the given values to degrees Fahrenheit, substitute the given values into the equation to get F1 and F2 respectively:

For (25, F1):

F = 9/5 C+32      (put C= 25 in the equation)

F1 = 9/5(25) + 32

F1 = 45 +22

F1 = 77 degrees Fahrenheit

For (−30, F2):

F = 9/5 C+32       (put C= -30 in the equation)

F2 = 9/5(-30) + 32

F2 = -54 + 32

The volume of the largest box that can be made from the rectangular cardboard obtained by using the value of the derivative of the function for the volume at the extremum point is 18 cubic feet

An extremum of a function is the point where the value of the function is a maximum or a minimum.

The side length of the cut out squares = x

The width of the rectangular cardboard = 5 feet

The length of the rectangular cardboard = 8 feet  

The length of the side of the cut square = 8 - 2·x

Width of the side of the cut square = 5 - 2·x

Height of the cut square = x

Volume of the cut square, V = (8 - 2·x) × (5 - 2·x) × x = 4·x³ - 26·x² + 40·x

When the volume of the box is largest, we have;[tex]V' = \dfrac{d}{dx} \left(4\cdot x^3 - 26\cdot x^2 + 40\cdot x\right) = 12\cdot x^2 - 52\cdot x + 40=0[/tex]

12·x² - 52·x + 40 = 0

3·x² - 13·x + 10 = 0

Which gives;

(3·x - 10)·(x - 1) = 0

The dimensions of the cut square that gives the maximum volume are therefore;

x = 1 or x = 10/3

When x = 10/3, we have;

V = (8 - 2×(10/3)) × (5 - 2×(10/3)) × (10/3) ≈ -200/27 < 0

When x = 1, we have;

V = (8 - 2×1) × (5 - 2×1) × 1 = 18

The value of x that gives the maximum volume is therefore, x = 1

The dimensions of the box that give the maximum volume are therefore;

Height = x = 1

Length = 8 - 2×1 = 6

Width = 5 - 2 × 1 = 3

The dimensions of the box that gives the maximum volume are;

Height = 1 ft

Length = 6 ft

Width = 3 ft
