Remark

f(x) = 9x^2 - 5x + 3 is given. The notation means that wherever you see and x on the right, you replace it with the x in the brackes on the left. f(3) is a direction, not anything you have to adjust or manipulate.

Solution

f(-3) = 9*(-3^2) - 5*(-3) + 3       (-(3))^2 = -3 * -3 = 9  two minuses make a +

f(-3) = 9*(-3)(-3) + 15 + 3          -3 times an operation of minus equals a +

f(-3) = 9 * 9 + 15 + 3

f(-3) = 81 + 15 + 3

Answer: f(-3) = 99

Answer:

B) 55, 68,81

Step-by-step explanation:

42-29=13

29-16= 13

So 42 + 13= 55

55+ 13= 68

68+ 13= 81

Answer:

B)  55, 68, 81

Step-by-step explanation:

Given sequence:  3, 16, 29, 42

To determine if the sequence is arithmetic or geometric, work out the difference in the terms.

[tex]\sf 3 \underset{+13}{\longrightarrow} 16 \underset{+13}{\longrightarrow} 29 \underset{+13}{\longrightarrow} 42[/tex]

This sequence adds 13 each time, so as the common difference is constant, it is an arithmetic sequence.  To find the next term in the sequence, simply add 13 to the last term:

42 + 13 = 55

55 + 13 = 68

68 + 13 = 81

Therefore, the next three terms in the given sequence are 55, 68, 81

To solve this using the general form of an arithmetic sequence:

[tex]a_n=a+(n-1)d[/tex]

where:

Given:

[tex]\begin{aligned}\implies a_n & =3+(n-1)13\\ & = 3+13n-13\\ & = 13n-10\end{aligned}[/tex]

Therefore, the next 3 terms in the sequence are:

[tex]\implies a_5=13(5)-10=55[/tex]

[tex]\implies a_6=13(6)-10=68[/tex]

[tex]\implies a_7=13(7)-10=81[/tex]

Answer:

Option A, [tex]n =[/tex] ± [tex]17[/tex]

Step-by-step explanation:

Step 1:  Add 29 to both sides

[tex]n^2 - 29 = 260[/tex]

[tex]n^2 - 29 + 29 = 260 + 29[/tex]

[tex]n^2 = 289[/tex]

Step 2:  Square root both sides

[tex]\sqrt{n^2} = \sqrt{289}[/tex]

[tex]n =[/tex] ± [tex]17[/tex]

Answer:  Option A, [tex]n =[/tex] ± [tex]17[/tex]

The profit to the company will be maximum that means pear company should produce 11000 phones for the maximum profit.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Function representing the cost to the manufacturer is,

C(x) = -20x²+ 48000x + 19351

A function that represents the revenue generated is,

R(x) = -23x² + 114000x

Function representing profit to the company,

Profit = Revenue generated - Cost price

        = -23x² + 114000x - ( -20x²+ 48000x + 19351)

        = -23x² + 20x² + 114000x - 48000x - 19351

P(x)  = -3x² + 66000x - 19351

Since this function is a quadratic function, the maximum price generated would be x = -b/2a

From the given quadratic function, a = (-3), b = 66000 and c = -19351

x = - 66000/ 2(-3)

x = -66000/-6

x = 11000

x = 11000 the profit to the company will be maximum.

That means pear company should produce 11000 phones for the maximum profit.

Answer:

Step-by-step explanation:

Use the slope formula.

Answer:

[tex]\boxed{\text{Slope} = -\huge\text{(}\dfrac{12}{7}\huge\text{)}}[/tex]

Step-by-step explanation:

Slope formula:

[tex]\text{Slope} = \dfrac{\text{Rise}}{\text{Run}}} = \dfrac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]

Using the coordinates (8, -9) and (1, 3), we obtain the following:

Substitute the coordinates of both the points in the slope formula to obtain the fraction that represents the slope.

[tex]\implies \text{Slope} = \dfrac{3 - (- 9)}{1 - 8}[/tex]

To obtain a specific fraction or whole number that represents the slope, we need to simplify the numerator and the denominator.

[tex]\implies \text{Slope} = \dfrac{3 + 9}{-7}[/tex]

[tex]\implies \text{Slope} = \dfrac{12}{-7}[/tex]

Use parenthesis and take out the "negative sign" from the denominator.

[tex]\implies \boxed{\text{Slope} = -\huge\text{(}\dfrac{12}{7}\huge\text{)}}[/tex]

Let's break this problem into a few steps:

            ⇒ Amount of Candybar: Candy - (1/2)Candy = (1/2)Candy

           ⇒ Amount of Candy left:  

                    Total amount of candy - (1/6) * Total amount of candy

                                                 = (1/2) Candy - (1/6) *(1/2)Candy

                                                 = (1 - 1/6) * (6/7) Candy

                                                 = 5/6 * 1/2 = 5/12 Candy

Thus there is 5/12 of the candy left.

Answer:

The parent sine graph [tex]y=sin(x)[/tex] has a range of -1 ≤ y ≤ 1

It crosses the x-axis x = 0° ± 180°n

The maximum points occur when x = 90° ± 360°n and y = 1

The minimum points occur when x = 270° ± 360°n and y = -1

The sketch the graph of function [tex]y=sin(x)+2[/tex] we simply move the graph of [tex]y=sin(x)[/tex] up 2 units.

So this means it will have a range of 1 ≤ y ≤ 3

It no longer crosses the x-axis.

The maximum points occur when x = 90° ± 360°n and y = 3

The minimum points occur when x = 270° ± 360°n and y = 1

Based on the calculations, the distance between the garden and the woods is equal to 383 meters.

First of all, we would assign a variable to the different speeds of the turtle and hedgehog as follows:

Mathematically, distance is given by this formula:

Distance = speed × time

Translating the word problem into an algebraic expression, we have;

If they both meet in 5 hours:

D = (S₁ + S₂) × 5  

D = 5S₁ + 5S₂      ......equation 1.

Turtle's speed is 10 meters per hour slower than the hedgehog:

S₁ = S₂ - 10    .....equation 2.

If the turtle had left home 4.5 hours earlier than the hedgehog had left his home:

9.5S₁ + 5S₂ = D + 150    .....equation 3.

Substituting enq. 2 into eqn. 1, we have:

D = 5(S₂ - 10) + 5S₂

D = 5S₂ - 50 + 5S₂

D = 10S₂ - 50      .....equation 4.

Equating eqn. 3 and eqn. 4, we have:

10S₂ - 50 = 9.5(S₂ - 10) + 5S₂ - 150

10S₂ - 50 = 9.5S₂ - 95 + 5S₂ - 150

10S₂ - 50 = 14.5S₂ - 245

14.5S₂ - 10S₂ = 245 - 50

4.5S₂ = 195

S₂ = 195/4.5

S₂ = 43.3 m/h.

Now, we can find the distnace:

D = 10S₂ - 50

D = 10(43.3) - 50

D = 433 - 50

D = 383 meters.

s = 10

Step-by-step explanation:

This Triangle is a Right Triangle with two equal sides ( because there are two equal angles )

Pytha. Theorem

A² + B² = C²

since we have two equal sides the A = B = s

then

s² + s² = c²

2s² = c²

2s² = (10sqrt2)²

2s² = 100 x 2

2s² = 200

s² = 200/2 = 100

s = sqrt ( 100 )
