Answer:

h(x) = x² + 24

Step-by-step explanation:

First solve for g(2) in g(x) = x³ + 4x² + 8x - 7 by simply substituting 2 in x variable. The result is 33.

Then get the sum of f(x) and 33 to find h(x).

In this case, "degrees of freedom" , or "df":

  "df" = n - 1 ;  

  in which:  "n = the numeric value of the sample size."

   Given:  "n = 99" ;  we can plug that value into the formula:

         "df" = n - 1 = 99 - 1 = 98 .

Answer:

Step-by-step explanation:

From the picture attached,

From ΔABC,

m∠B = 180° - (m∠C + m∠A)

        = 180° - (90° + 32°)

        = 180° - 122°

        = 38°

Now we have to find the trigonometric ratio of BC and AB from ΔABC,

Since, sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

sin(32°) = [tex]\frac{BC}{AB}[/tex]

[tex]\frac{BC}{AB}=0.53[/tex]

Therefore, ratio of BC and AB represents the "sine of angle A".

Answer:

48 sq inches

Step-by-step explanation:

Given that,

Ribbon used around a bulletin broard is 28 inches

The length of her board is 6 inches

Let B is breadth of her board. 28 inches is perimeter. The perimeter of rectangle is given by :

P = 2(L+B)

28=2(6+B)

14=6+B

B=8 inches

The area of a rectangle is given by :

A = L×B

A = 8×6

A=48 sq inches

So, the area of her board is 48 sq inches

Answer:

The correct answer is 7 weeks 34 WPM

Step-by-step explanation:

The number of weeks and words typed will be D. 7weeks;34 WPM

Based on the information given, the formula to calculate my words per minutes = 13 + 3n

The formula to calculate my friend's words per minutes = 20 + 2n

Therefore, we'll equate both equations together and this will be:

13 + 3n = 20 + 2n

Collect like terms

3n - 2n = 20 - 13

n = 7.

Therefore, the WPM will be:

= 13 + 3n

= 13 + 3(7)

= 13 + 21

= 34

The number of weeks and words typed will be 7weeks;34 WPM

The size of a matrix is simply the number of rows and the number of columns. Something like 2x3 means we have 2 rows and 3 columns.

Explanation:

When saying something like [tex]E_{23}[/tex] we are looking at the item in the second row and third column of matrix E.

The acronym DNE stands for "Does Not Exist". It's another way of saying "Undefined". For instance, note how matrix E has only 3 columns. When we write [tex]E_{34}[/tex] we're asking about something in the fourth column, but no such column exists.

Answer:

y = 2x + 1

Step-by-step explanation:

1. Find the slope: change in y/change in x

[tex]\frac{5-1}{2-0}[/tex] = 2

Slope: 2

2. Find y-intercept by substituting in a point (0, 1)

y = 2x + b

1 = b

3. Put the equation together

y = 2x + 1

The equation of the line passing through the points (0, 1) and (2, 5) is y = 2x + 1.

y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.

The equation of a line in slope intercept form is,

y = mx + c

Here m is the value of the slope and c is y intercept.

Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.

Given two points (0, 1) and (2, 5).

Slope, m = (5 - 1) / (2 - 0)

               = 4 / 2

               = 2

c is the y coordinate when x = 0.

We have that point given (0, 1).

So c = 1

Substituting m = 2 and c = 1 in the general form, we get,

y = 2x + 1

Hence the equation of the line is y = 2x + 1.

Answer:

Iris weighs 55 pounds, Ivan weighs 65 pounds.

Step-by-step explanation:

Divide 120 by 2: 60

Then make the 10 pound difference by adding and subtracting 5 to 60 for each answer: 55 and 65.

Iris = 55 pounds

Ivan = 65 pounds

Let x be Iris and y be Ivan.

x+ y = 120

y-10+ y = 120

2y - 10 = 120

2y = 120 + 10

2y = 130

y = 130/2

y = 65 pounds

x = y-10

= 65-10

x = 55 pounds

Answer: y - 4 = 1/5 * (x+3)
