Write the quadratic equation the has the roots (-1-√2)/3 and (-1+√2)/3 if its coefficient with x^2 is equal to...1

Answer:

114

Step-by-step explanation:

so lets call shelf 1 x

shelf 2 is twice size + 18 of shelf 1 so it is 2(x)+18

shelf 3 is 12 less than shelf 1 so x-12

shelf 4 is four more so x+4

Add them all together and it should be 5x+10= 2.5 m or 250 cm

Solve for x using cm

then plug into shelf 2 equation

Answer:

2 metres per 1 hour

12 metres per 6 hours

30 minutes to glide 1 metre.

Step-by-step explanation:

1. To find the average speed, simply divide the distance covered by the amount of time taken, like so:

4 metres / 2 hours = 2 metres per 1 hour

2. To find how many metres the snail will glide in 6 hours, multiply the 2 metres per 1 hour by 6, like so:

6(2 metres per 1 hour) = 12 metres per 6 hours

3. Because we know that 2 metres take 1 hour to glide over, if we divide 2 in half, we get 1, so we can also divide 1 hour in half to get 30 minutes. Therefore, it takes 30 minutes to glide 1 metre.

Hope this helps :)

what is 4/2/3 x 1/3/7 ?

[tex]6\frac{2}{21}[/tex]

Step-by-step explanation:

Rewriting our equation with parts separated

[tex]4 +\frac{2}{3} + 1 +\frac{3}{7}[/tex]

Solving the whole number parts

[tex]4 + 1 =5[/tex]

Solving the fraction parts

[tex]\frac{2}{3}+\frac{3}{7} =?[/tex]

Find the LCD of 2/3 and 3/7 and rewrite to solve with the equivalent fractions.

LCD = 21

[tex]\frac{14}{21} +\frac{9}{21} =\frac{23}{21}[/tex]

Simplifying the fraction part, 23/21,

[tex]\frac{23}{21} =1\frac{2}{21}[/tex]

Combining the whole and fraction parts

[tex]5 + 1+ \frac{2}{21} =6\frac{2}{21}[/tex]

Hence, The answer is [tex]6\frac{2}{21}[/tex]

Inequalities are used to represent unequal expressions.

The inequality is: (c) [tex]\mathbf{3p + 6 \ge 18}[/tex]

The given parameter is:

[tex]\mathbf{Free = 6}[/tex]

Represent the number of 3-point field goals with p.

So, the total number of points is:

[tex]\mathbf{Total = 3 \times p + Free}[/tex]

[tex]\mathbf{Total = 3 p + Free}[/tex]

Substitute 6 for Free

[tex]\mathbf{Total = 3 p + 6}[/tex]

He scored no fewer than 18 points, means that:

He scored 18 or more points

So, the inequality is:

[tex]\mathbf{Total = 3 p + 6 \ge 18}[/tex]

Rewrite as:

[tex]\mathbf{3p + 6 \ge 18}[/tex]

Hence, the correct option is (c)

Beckett spent $88 in total his estimate of $80 is wrong.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Beckett went to two different stores at the mall. He purchased a $36 hat at the first store and a $52 pair of shoes at the second. Beckett estimates that he spent a little less than $80 in total.

The total spending will be calculated as,

Total = 52 + 36

Total = $88

The estimated spending is $80. Therefore, Beckett spent $88 in total his estimate of $80 is wrong.

Step-by-step explanation:

Rates of change are the change of a quantity over another.

The rate of change of the mass position at 2.1 seconds is -89.6 cm/ s

The given parameters are:

[tex]\mathbf{A = |5|}[/tex] -- the amplitude

[tex]\mathbf{T = \frac 13}[/tex] --- the period

The position of the mass is modeled by:

[tex]\mathbf{y= Acos(wt)}[/tex]

Where:

[tex]\mathbf{w = \frac{2\pi }{T}}[/tex]

So, we have:

[tex]\mathbf{w = \frac{2\pi}{1/3}}[/tex]

[tex]\mathbf{w = 6\pi }[/tex]

[tex]\mathbf{y= Acos(wt)}[/tex] becomes

[tex]\mathbf{y = |5|cos(6\pi t)}[/tex]

[tex]\mathbf{y = 5cos(6\pi t)}[/tex]

Differentiate

[tex]\mathbf{y' = 5 \times -sin(6\pi t) \times (6\pi)}[/tex]

[tex]\mathbf{y' = -30\pi sin(6\pi t) }[/tex]

When t = 2.1, we have:

[tex]\mathbf{y' = -30\pi sin(6\pi \times 2.1) }[/tex]

[tex]\mathbf{y' = -30\pi sin(12.6\pi) }[/tex]

[tex]\mathbf{y' = -30\pi \times 0.9510}[/tex]

[tex]\mathbf{y' = -89.6296}[/tex]

Approximate

[tex]\mathbf{y' = -89.6}[/tex]

Hence, the rate of change of the mass position at 2.1 seconds is -89.6 cm/ s
