Answer:

f(4) = 59

Step-by-step explanation:

Given:

f(1) = 3

f(n) = f(n-1)2 + 5

Idea:

We want to find the value of f(4), so let's substitute n with 4.

f(n) = f(n-1)2 + 5

f(4) = f(4-1)2 + 5

f(4) = f(3)2 + 5

We see that we have to evaluate f(3) before we can calculate f(4).

So let's try to calculate f(3).

f(3) = f(3-1)2 + 5

f(3) = f(2)2 + 5

Again we have to calculate f(2) before we can calculate f(3). So what do we do?

Calculations:

The best approach is to start from the bottom. First let calculate the value of f(2) and then f(3) and finally f(4).

f(1) = 3 (this was given)

f(2) = f(2-1)2 + 5

    = f(1)2 + 5 (this time we know the value of f(1)!)

    = 3 × 2 + 5

    = 6 + 5
    = 11

f(3) = f(3-1)2 + 5

    = f(2)2 + 5 (we calculated f(2) in the previous step: f(2) = 11)

    = 11 × 2 + 5

    = 22 + 5
    = 27

f(4) = f(4-1)2 + 5

    = f(3)2 + 5

    = 27 × 2 + 5

    = 51 + 5
    = 59

Option C is correct, the missing denominator of the solution is 3.

A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .

The given  quadratic equation is  3x² + 4x - 2 = 0.

We have to use the quadratic formula to find root

x = -b±√b²-4ac/2a

From the equation a = 3, b= 4 and c=-2

Plug in these in formula

x = -4 ±√ 4²-4(3)(-2)/2(3)

x = -4 ±√16+24/6

x = -4 ±√40/6

x = -4 ± 2√10/6

x = -2 ± √10/3

Hence, the missing denominator of the solution is 3.

Answer:

C) 312 cm^2

Step-by-step explanation:

To find the total area of the composite figure, you must sum the individual components of the figure.

First, we find the area of the rectange, which is A = l x w = 16 x 12 = 192

Second, we find the area of the first triangle which is also equal to the area of the second triangle, so instead of finding the base times height and dividing by 2, we will simply find the area of base times height and it will work for both trianges.

A = b x h x 1/2 x 2 = 10 x 12 = 120

120 + 192 = 312 cm^2

The combine ratios will be a1:a2:a3 = 1:2:3  as the a1 is equal to a2 and the 2:4 shows the mixing 2 red with 4 blue paint.

It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign : between the numbers.

We have:

Purple 1 is made by mixing red(a1) and blue(a2) in a ratio of 1 : 2.

Purple 2 is made by mixing red(a3) and blue(a4) in a ratio of 1 : 3.

Here the options are not given, but we can combine the above ratios like:

a1:a2:a3 = 1:2:3  (a1 = a3)

If we multiply with any number (let's say 2) in the ratio 1 : 2 and 1 : 3

We get:

2:4  (mixing 2 red with 4 blue paint) and

2:6  (mixing 2 red with 6 blue paint)

Thus, the combine ratios will be a1:a2:a3 = 1:2:3  as the a1 is equal to a2 and the 2:4 shows the mixing 2 red with 4 blue paint.

15/2.5 = 6

Answer: (3,3)

Step-by-step explanation:

The given information is,

→ a = -8

→ b = -7

→ c = 6

Let's verify the problem,

→ (a+b) + c = a+ (b+c)

→ (-8 - 7) + 6 = -8 + (-7 + 6)

→ -15 + 6 = -8 - 1

→ -9 = -9

→ [ LHS = RHS ]

Hence, it is equal and verified.

The equation most closely models the line of best fit for the scatter plot is y = 2.5x

A line is the distance between two points. The equation of a line in point-slope form is given as y =mx + b

Using the coordinate points on the line (3, 5000) and (9, 20000)

Get the slope

Slope = 20000-5000/9-3
Slope = 15000/6 = 2500

Determine the y-intercept

5000 = 2500(3) + b

b = 5000 - 7500
b = -2500

Determine the equation

y = 2.5x - 2.5

Hence the equation most closely models the line of best fit for the scatter plot is y = 2.5x

The value of the line in the middle of the box is 165

The value of the third line in the box is 167.

The value of the whisker on the left is 176.

A box plot is used to study the distribution and level of a set of scores. The box plot has two whiskers. The whisker on the left represents the minimum value and the  whisker on the right represents the maximum value.

The first line on the box to the left represents the lower (first) quartile. The next line on the box represents the median. The third line on the box represents the upper (third) quartile.

Maximum value = range + minimum value

143 + 33 = 176

Upper quartile = lower quartile + interquartile range
