f (x) = -3x + 5x2 + 8 has roots.

Explanation:

The data from the stem-and-leaf plot is:

10,

24,25,26,

30,30,32,33,

40,45,46

Add up those values

10+24+25+26+30+30+32+33+40+45+46 = 341

Then divide over n = 11 which is the sample size.

341/11 = 31 is the arithmetic mean.

Answer:

341/11 = 31 is the arithmetic mean.

Step-by-step explanation:

Rise over run is the slope, m

m=2/5

a)  the slope is 2/5 = .4 which is below the boundary guideline.  So no this is not with in carpenter's guidelines

b) the image below show a line with slope 2/5 but with intercept 3

c) the stairs can be draw on the line with rise 2 run 5   from the line.  see image

d)equation is in image

2.

a) count the squares

horizontal distance =3

vertical distance =3

b)  slope is vertical distance over horizontal distance  so m= 3/3 =1

The measure of ∠B is 41°

Answer:

25

Step-by-step explanation:

4a +12 -2c + c

4( ) + 12 - 2( ) + ( )

4(4) + 12 - 2(3) + 3

16 + 12 - 6 + 3

28 - 6 + 3

22 + 3

25

Helping in the name of Jesus.

Therefore,  4a  +   12   -   2c   +   c  =   25

       a  =   4  

       c  =   3

        4a  +   12   -   2c   +   c

       (4)(4)  +  12  -     (2)(3)   +    3

         16     +   12   -   (2)(3)   +    3

         28      -            (2)(3)    +    3

         28     -   6     +     3

         22    +      3   =   25

Draw a conclusion:

     4a  +   12   -   2c   +   c   =  25

To find out what percentage of the daily allowance of total fat Bud had when he ate the cheeseburger, we first need to calculate how many grams of total fat he consumed, and then divide that by the recommended daily allowance, and finally multiply by 100 to get the percentage.

Bud ate a cheeseburger containing 30 grams of total fat. The recommended daily allowance of total fat for a 2,000 calorie diet is 64 grams. Therefore, we can calculate the percentage of the daily allowance that Bud had by dividing the amount of fat he consumed by the recommended daily allowance and then multiplying by 100:

Percentage of daily allowance = (30 / 64) x 100 = 46.875%

So, Bud had 46.875% of the recommended daily allowance of total fat when he ate the cheeseburger.

Answer:

46.875 %

Step-by-step explanation:

30 grams of fat out of 64 grams

30/64 =.46875

Change to percent form

46.875 %

Answer:

B. 13

Step-by-step explanation:

\(10+(\frac{1}{2}) ^{4} *48=\\\\10+\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*\frac{1}{2}*48=\\\\10+\frac{1}{16}*48=\\\\10+\frac{48}{16}=\\\\10+3=\\\\13\)

Answer:

Step-by-step explanation:

First, use PEMDAS

Parenthesis, Exponents, multiplication, division, addition, subtraction

1/2 * 1/2 * 1/2 * 1/2 = 1/16 = Parenthesis and Exponents

1/16*48 = 48/16 = 3 = Multiplication and Division

3+10 = 13 = Addition

This can conclude that 13 is the answer.

Answer:

20 units

Step-by-step explanation:

(16, 0), (0, 12)

(x₁, y₁)   (x₂, y₂)

d = √(x₂ - x₁)² + (y₂ - y₁)²

d = √(0 - 16)² + (12 - 0)²

d = √(-16)² + (12)²

d = √(-16)² + (12)²

d = √256 + 144

d = √400

d = 20

Answer:

-6 is the slope

Step-by-step explanation:

In order to find the slope you need to do put it in slope intercept form

y2-y1/x2-x1 is slope-intercept  form

(-7 - (-1))/4-3 = (-7 +1)/1 = -6/1 = -6

Answer:

The slope in -2

Step-by-step explanation:

to graph this use the slope-intercept form of y=-2x+1
