The root of 18 without using a calculator

There is a formula that gives an approximation of a square root without a calculator. This is given as:

The total yards gained or lost is the algebraic sum so the resultant yards is -15 yards thus they lose 15 yards.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

Subtraction = Minus of any two or more numbers.

Summation = addition of two or more numbers or variable

Let's consider all gained yards by positive (+) and all lost yards by negative (-).

Given that,

In the first play = +8 yards (gain)

In second play = -12 yards (lost)

In the third play = 11 yards (Lost)

So total yards = +8 - 12 - 11 = -15 (Lost)

Therefore, the football team lost 15 yards.

Hence "The total yards gained or lost is the algebraic sum so the resultant yards is -15 yards thus they lose 15 yards".

There is a 5% chance that second graders will be faster than 94.597 wpm.

Sample size = 21

standard deviation = 10 wpm

SE = 10/sqrt(21) = 2.18 as a consequence.

Let X be the average reading speed of 21 second-grade students. z = (X - 91)/2.18 Normal(91,2.18) (91,2.18).

If the 95th percentile of a standard normal variable z is 1.65 [5% probability], the outcome is 91 + 1.65 x 2.18 = 94.597.

So there's a 5% chance that the average reading speed of a random sample of 21 second-graders will be faster than 94.597 wpm.

Step-by-step explanation:

Simple interest rate means if I have "P" amount that I initially deposited, then every year this amount increases by "x% of P" or the original amount I deposited. So it's increasing by the same amount each year, unlike compound interest.

The formula for calculating the amount of interest is: [tex]I=P*r*t[/tex]

Where, r is the interest rate, t is the time unit, and P is the initial amount.

In most cases the t will be expressed in years, and one thing to note is the r is the interest rate in decimal form, so [tex]30\%=0.30[/tex], we want to convert it to decimal form by dividing by 100

We know the amount of interest, as it's given to us as 9,000, and the principle amount or initial amount, given to us as 60,000, and also the time which is given to us as 3 years.

So we know that:

[tex]I=9,000\\P=60,000\\t=3\\[/tex]

Plugging all these values into the equation we get:

[tex]9,000=60,000*3*r\\\\9,000=180,000*r\\\\\frac{9,000}{180,000}=r\\\\0.05=r[/tex]

as noted above, this interest rate, "r" is expressed in decimal form. Since we have to divide by 100 to convert from percentage to decimal, we have to multiply by 100 to convert from decimal to percentage.

this gives us: [tex]r=5\%[/tex]

Q.12 The polynomials are 2 and 3

What is polynomial ?

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables. An example of a polynomial of a single indeterminate x is x² − 4x + 7.

Given, p(x) = -x² + x + 2

p has a degree 2

Let, a = 1 + i√2

      b = 1 - i√2

a + b = 1 + i√2 + 1 - i√2

        = 2

a * b = (1 + i√2) * (1 - i√2 )

        = 1 - (i√2)²

        = 1 - i²*2    (where, i² = -1)

Hope this helps! :)

the maximum height is 254 feet.

Answer:

a)  0.5 seconds and 3.5 seconds.

b)  5.98 seconds (2 d.p.)

c)  No.

d)  254 feet at 2 seconds.

Step-by-step explanation:

Given equation:

[tex]h=-16t^2+64t+190, \quad t \geq 0[/tex]

where:

To calculate when the object will be 218 feet above the ground, substitute h = 218 into the equation and solve for t:

[tex]\begin{aligned}\implies -16t^2+64t+190 & = 218\\-16t^2+64t+190-218& = 0\\-16t^2+64t-28 & = 0\\-4(4t^2-16t+7) & = 0\\4t^2-16t+7 & = 0\\4t^2-14t-2t+7 &=0\\2t(2t-7)-1(2t-7)&=0\\(2t-1)(2t-7)&=0\\\implies 2t-1&=0\implies t=\dfrac{1}{2}\\\implies 2t-7&=0 \implies t=\dfrac{7}{2}\end{aligned}[/tex]

Therefore, the object will be 218 feet about the ground at 0.5 seconds and 3.5 seconds.

The object strikes the ground when h is zero. Therefore, substitute h = 0 into the equation and solve for t:

[tex]\begin{aligned}\implies -16t^2+64t+190 & = 0\\-2(8t^2-32t-95) & = 0\\8t^2-32t-95 & = 0\end{aligned}[/tex]

Use the quadratic formula to solve for t:

[tex]\implies t=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]

[tex]\implies t=\dfrac{-(-32) \pm \sqrt{(-32)^2-4(8)(-95)} }{2(8)}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{1024+3040} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{4064} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{16 \cdot 254} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{16} \sqrt{254} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm 4 \sqrt{254} }{16}[/tex]

[tex]\implies t=\dfrac{8\pm \sqrt{254} }{4}[/tex]

As t ≥ 0,

[tex]\implies t=\dfrac{8+ \sqrt{254} }{4}\quad \sf only.[/tex]

[tex]\implies t=5.98 \sf \; s \; (2 d.p.)[/tex]

Therefore, the object strikes the ground at 5.98 seconds (2 d.p.).

To find if the object will reach a height of 300 feet above the ground, substitute h = 300 into the equation and solve for t:

[tex]\begin{aligned}\implies -16t^2+64t+190 & = 300\\-16t^2+64t+190-300 & =0\\-16t^2+64t-110 & =0\\-2(8t^2-32t+55) & =0\\8t^2-32t+55& =0\end{aligned}[/tex]

Use the quadratic formula to solve for t:

[tex]\implies t=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}[/tex]

[tex]\implies t=\dfrac{-(-32) \pm \sqrt{(-32)^2-4(8)(55)} }{2(8)}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{1024-1760} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{-736} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{16 \cdot -1 \cdot 46} }{16}[/tex]

[tex]\implies t=\dfrac{32 \pm \sqrt{16} \sqrt{-1} \sqrt{ 46}}{16}[/tex]

[tex]\implies t=\dfrac{32 \pm 4i\sqrt{ 46} }{16}[/tex]

[tex]\implies t=\dfrac{8\pm \sqrt{ 46} \;i}{4}[/tex]

Therefore, as t is a complex number, the object will not reach a height of 300 feet.

The maximum height the object can reach is the y-coordinate of the vertex.  

Find the x-coordinate of the vertex and substitute this into the equation to find the maximum height.

[tex]\textsf{$x$-coordinate of the vertex}: \quad x=-\dfrac{b}{2a}[/tex]

[tex]\implies \textsf{$x$-coordinate of the vertex}=-\dfrac{64}{2(-16)}=-\dfrac{64}{-32}=2[/tex]

Substitute t = 2 into the equation:

[tex]\begin{aligned}t=2 \implies h(2)&=-16(2)^2+64(2)+190\\&=-16(4)+128+190\\&=-64+128+190\\&=64+190\\&=254\end{aligned}[/tex]

Therefore, the maximum height of the object is 254 feet.

It takes 2 seconds for the object to reach its maximum height.

Explanation:

A right triangle has exactly one angle that is 90 degrees. This is called a right angle.

The other two angles are acute, which means they are less than 90 degrees. An example would be 30 degrees and 60 degrees.

If 30 degrees is an interior acute angle, then 180-30 = 150 degrees is the exterior obtuse angle. Similarly, the adjacent angle to the 60 is 180-60 = 120 degrees.

This example shows we have two obtuse exterior angles. This applies to any right triangle, and not just this particular one.
