The zeros of a polynomial are the values of x for which the polynomial is equal to 0.

What is polynomial?

A polynomial is a mathematical expression consisting of a sum of terms, each term including a variable or variables raised to a non-negative integer power. It is an algebraic expression that can involve constants, variables, and exponents.

To find the rational zeros of a polynomial, use the Rational Zero Theorem. This theorem states that if the polynomial is written in standard form, ax^n + bx^n-1 + cx^n-2 + ... + k = 0, then the possible rational zeros are any rational number that can be expressed as p/q, where p is a factor of k (the constant) and q is a factor of a (the leading coefficient).

The board in shape of rectangle must be at least 6.4 feet.

What is a rectangle?

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles. The opposite sides of the rectangle are equal in length which makes it different from a square.

For example, if one side of a rectangle is 20 cm, then the side opposite to it is also 20 cm.

A rectangle has two diagonals, that bisects each other. Both the diagonals are equal in length.

Perimeter, P = 2 (Length + Width)

Area of Rectangle=Length*Breadth

Now,

Given length of board they want to cut=1 3/5 feet=8/5 feet.

No. of board they want to cut=4

so, length of rectangular board must be at least=4*8/5 feet

=32/5=6.4 feet

30 degrees below sea level refers to a location that is 30 degrees lower in elevation than the average sea level, which is a reference point fomeasuring elevation and depth, and which can vary depending on the location.

Sea level is the average level of the surface of the ocean, which is used as a reference point for measuring elevation and depth. The term "sea level" can also refer to the specific measurement of the height of the ocean's surface at a specific location.

30 degrees below sea level refers to a location that is 30 degrees lower in elevation than the average sea level. This means that the location is 30 degrees lower in elevation than the reference point of the average surface of the ocean. This can be measured in either meters or feet, depending on the unit of measurement being used.

One way to think about 30 degrees below sea level is to imagine a point 30 degrees below the level of the water in a swimming pool. This would be considered a very deep point in the pool, and would be much lower than the surface of the water. Similarly, a location that is 30 degrees below sea level is much lower in elevation than the average sea level.

It's important to note that the concept of sea level can vary depending on the location, as sea level can vary due to factors such as ocean currents, tides, and the shape of the ocean floor. Therefore, the reference point for sea level can be different in different locations.

In summary, 30 degrees below sea level refers to a location that is 30 degrees lower in elevation than the average sea level, which is a reference point for measuring elevation and depth, and which can vary depending on the location.

Answer:

Step-by-step explanation:

(a) To find the time necessary to type 50 words per minute, we need to solve the equation:

157/1 + 5.4e^-0.12t = 50

Rearranging the equation to isolate e^-0.12t and using the natural logarithm, we can find t:

ln(N - 157) = ln(5.4) - 0.12t

-ln(N - 157) = 0.12t - ln(5.4)

0.12t = ln(5.4) + ln(N - 157)

t = (ln(5.4) + ln(N - 157)) / 0.12

Plugging in N = 50, we get:

t ≈ 11.52 weeks

(b) To find the time necessary to type 75 words per minute, we follow the same steps as above:

157/1 + 5.4e^-0.12t = 75

ln(N - 157) = ln(5.4) - 0.12t

-ln(N - 157) = 0.12t - ln(5.4)

0.12t = ln(5.4) + ln(N - 157)

t = (ln(5.4) + ln(N - 157)) / 0.12

Plugging in N = 75, we get:

t ≈ 9.32 weeks

Answer:

For 50 wpm : 7.7 weeks approximately

For 75 wpm : 13.3 weeks approximately

Step-by-step explanation:

Given the relationship between N, the typing speed and t, the number of weeks of lessons as:

[tex]\mbox{\large N= \dfrac{157}{1+5.4e^{-0.12t}}}[/tex]

To solve for t for a particular N

cross-multiply the left side with the right side denominator to get

[tex]\mbox{\large 1+5.4e^{-0.12t } = \dfrac{157}{N}}[/tex]

For N= 50 this works out to

[tex]\mbox{\large 1+5.4e^{-0.12t } = \dfrac{157}{50}}[/tex]

[tex]\mbox{\large 5.4e^{-0.12t } = \dfrac{157}{50} - 1}\\[/tex]
[tex]\mbox{\large 5.4e^{-0.12t } = \dfrac{157-50}{50} } = \dfrac{107}{5} = 2.14[/tex]

Divide by 5.4 both sides:

[tex]\mbox{\large e^{-0.12t } = \dfrac{2.14}{5.4}} = 0.3963\\[/tex]

Take natural logs on both sides

[tex]\mbox{\large \ln(e^{-0.12t}) = \ln(0.3963)\\}[/tex]

[tex]\mbox{\large \ln(e^{-0.12t}) = -0.12 \;\textrm{since $ln(e^x)$ = x}}[/tex]  since ln(eˣ) = x

ln(0.3963) = -0.9256

Therefore

[tex]t = \dfrac{-0.9256}{-0.12} = \dfrac{0.9256}{0.12} = {7.7133 \;weeks\approx \mbox{\large \boxed{7.7 \;weeks}}[/tex]

For N = 75, follow the same strategy and you will end up with

[tex]1+5.4e^{-0.12t}=\dfrac{157}{75} \\\\\\1+5.4e^{-0.12t}= 2.0933\\\\5.4e^{-0.12t} = 2.0933 - 1 = 1.0933\\\\e^{-0.12t} = \dfrac{1.0933}{5.4} = 0.2025\\\\[/tex]

Taking logs on both sides
[tex]-0.12t =-1.5971[/tex]

[tex]t = \dfrac{-1.5971}{-0.12} = 13.3097 \;weeks \approx \boxed{\mbox{\large 13.3 \;weeks}}[/tex]

The length of the hypotenuse for all the right-angled triangles are found using trigonometric functions.

What is the hypotenuse?

The longest side of a right-angled triangle, or the side opposite the right angle, is known as the hypotenuse in geometry. The Pythagorean theorem, which asserts that the square of the length of the hypotenuse equals the sum of the squares of the lengths of the other two sides, can be used to determine the length of the hypotenuse.

11) when angle = 30°

 perpendicular = 3

sin 30 = perpendicular/ hypotenuse

0.5 = 3/hypotenuse

hypotenuse = 6

12) sin 30 =perpendicular/ hypotenuse

  0.5 = 8/ hypotenuse

hypotenuse = 16

13) sin 60 = 11√3 / x

   Hypotenuse = x = 11√3/ sin 60 = 11√3 / (√3/2) = 22

14) sin 30 = perpendicular/ hypotenuse

   0.5 = 9/x

x = 18

15) cos 60 = base/ hypotenuse

     0.5 = 1 /x

     x = 2

16) sin 60 = 12√3/x

   √3/2 = 12√3/x

Convert mixed fractions to improper fractions:
[tex]2\dfrac{1}{4}=\dfrac{9}{4}[/tex]

[tex]2\dfrac{1}{4}=\dfrac{169}{4}[/tex]

The inequality becomes

[tex]-8t+\dfrac{9}{4}\ge \dfrac{169}{4}[/tex]

Multiply throughout by 4

[tex]-32t + 9 \ge 169[/tex]

[tex]\rightarrow -32t \ge 169-9\\\\-32t \ge 160\\\\-t \ge \dfrac{160}{32}\\\\-t \ge 5\\\\[/tex]

Multiply throughout by -1 (the inequality is reversed):

[tex]t \le -5[/tex]

The second option correctly represents this inequality

Option #1: Solve the inequality and graph the solution set.

Option #2: Test out the options to see which has solutions.

Let's do Option #2:

The first possible answer shows t < -5, so if we pick t = -10, we'd be in that interval.  Let's test if t = -10 is a solution:

      [tex]\begin{aligned}-8(-10) + 2\frac{1}{4} &\stackrel{?}{\geq} 42\frac{1}{4}\\[0.75em]80 + 2\frac{1}{4} &\stackrel{?}{\geq} 42\frac{1}{4}\\[0.75em]82\frac{1}{4} &\stackrel{\checkmark}{\geq} 42\frac{1}{4}\end{aligned}[/tex]

That checked!

So this alone tells us that the bottom two answers are not possible answers, since they do not include -10 in their sets.

But now we need to decide between the top answer or the one right below it.  The only difference between the two number lines is that the top one does NOT include x = -5, while the second one does.  So we need to test out if x = -5 is a solution, just like we did for x = -10.

     [tex]\begin{aligned}-8(-5) + 2\frac{1}{4} &\stackrel{?}{\geq} 42\frac{1}{4}\\[0.75em]40 + 2\frac{1}{4} &\stackrel{?}{\geq} 42\frac{1}{4}\\[0.75em]42\frac{1}{4} &\stackrel{\checkmark}{\geq} 42\frac{1}{4}\end{aligned}[/tex]

Because of the "or equal to" in the inequality, this does check.

Our answer is the second number line, with a closed circle at x = -5 and the shading to the left.

If you wanted to do this by solving the inequality, that work would look like this:

     [tex]\begin{aligned}-8t + 2\frac{1}{4} &\geq 42\frac{1}{4}\\[0.75em]-8t + 2\frac{1}{4}-2\frac{1}{4} &\geq 42\frac{1}{4}-2\frac{1}{4}\\[0.75em]-8t &\geq 40\\[0.75em]\dfrac{-8t}{-8}~ &{\boldsymbol{\leq}}~ \dfrac{40}{-8}\\[0.75em]t &\leq -5\end{aligned}[/tex]

Note that the inequality flipped because we divided both sides of the inequality by a negative number.

Solution of the integral is solved by substitution method :

Let us consider cos ( x ) = t  ____( 2 )

Now differentiate both the side we get,

-sin (x ) dx = dt  

⇒ sin (x ) dx = -dt  ____( 3 )

Substitute the value of ( 2 ) and ( 3 )  in ( 1 ) we get,

∫ t³ ( -dt )

The value of x in the triangle is 17 .

The perimeter of the triangle ABC is 86 units.

Triangle Proportionality Theorem states that If a line parallel to one side of a triangle intersects the other two sides, then it divides those sides proportionally.

Therefore, let's use the theorem to find the value of x in the triangle.

Hence,

20 / 4 = 2x - 4 / 6

cross multiply

120 = 4(2x - 4)

120 = 8x - 16

120 + 16 = 8x

136  = 8x

divide both sides by 8

x = 136 / 8

x = 17

Hence, let's find the perimeter of the triangle ABC.

The probability that at least one tag is lost is 0.75.

The probability that exactly one tag is lost is equal to the probability of the left tag being lost and the right tag being kept, plus the probability of the right tag being lost and the left tag being kept.

Using the formula for the probability of the union of two events, the probability that at least one tag is lost is:

P(A1 or A2) = P(A1) + P(A2) - P(A1 and A2) = 0.4 + 0.4 - 0.16 = 0.64

The probability of the left tag being lost and the right tag being kept is:

P(A1 and not A2) = P(A1) × (1 - P(A2)) = 0.4 × (1 - 0.4) = 0.24

The probability of the right tag being lost and the left tag being kept is:

P(A2 and not A1) = P(A2) × (1 - P(A1)) = 0.4 × (1 - 0.4) = 0.24

So, the probability of exactly one tag is lost, given that at least one tag is lost, is:

P(exactly one tag is lost | at least one tag is lost) = P(A1 and not A2 or A2 and not A1) / P(A1 or A2) = (0.24 + 0.24) / 0.64 = 0.75
