Answer:

They aare both the same

Step-by-step explanation:

three main trigonometry ratios are sin ,cos and tan.

1- Sine or sin θ = perpendicular / Hypotenuse .

2- Cosines or cos θ = base of triangle / Hypotenuse .

3- Tangent or tan θ = perpendicular of triangle / base of triangle.

Trigonometry

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

Trigonometric values are based on the angle theta and the values of the sides of triangle in which the theta angle is made.

for example - value of sin theta is equal to the side opposite to the theta angle divided by hypotenuse of the triangle and we will get the values of the sin trigonometric ratio.

The fries costs $1.49

Addition in math is a process of combining two or more numbers.

Given that, Keith ordered a hamburger for $2.25, a medium raspberry ice tea for $1.25, and a small sundae for  $1.25. He also ordered French fries. All of these items totalled $6.24.

Let the price of fries be x,

Therefore,

$2.25 + $1.25 + $1.25 + x = $6.24

$4.75 + x = $6.24

x = $6.24 - $4.75

x = $1.49

Hence, the fries costs $1.49

Answer:

3x + 4

Step-by-step explanation:

Using the distributive property simply means that when there is a number in front of a pair of parentheses, every value inside the parentheses is multiplied by the co-efficient to expand the parentheses.

Here, the coefficient is -2, therefore we multiply both terms inside the parentheses (x and -2) by -2 to expand them:

-2(x - 2) + 5x

= (-2)(x) + (-2)(-2) + 5x

Now we simply evaluate and combine like terms to simplify:

= -2x +4 +5x

= 3x + 4

Answer:

The population by 2020 is 191,900

Step-by-step explanation:

Given that;

population 2010 (population in 2010): 191000

the population grew from 2010 to 2015: by 3.9%

so, population by 2015 = [tex]191000(1 + \frac{3.9}{100})[/tex]

                                      = [tex]191000(1 + 0.039)[/tex]

                                      = [tex]191000(1.039)[/tex]

                                      = [tex]198449[/tex]

the population drop from 2015 to 2020: 3.3%

so, population by 2015 = [tex]198449(1 - \frac{3.3}{100})[/tex]

                                      = [tex]198449(1 - 0.033)[/tex]

                                      = [tex]198449(0.967)[/tex]

                                      = [tex]191,900.183[/tex]

Answer:

80 ducks (16+64)

Step-by-step explanation:

So if there were 32 brown ducks in the pond at first, then twice the amount of brown ducks (32).

32x2=64 white ducks

So now their are 64 white ducks at the pond. We still have to add how many brown ducks their were so…

64+32=96 ducks in total

But then as the white ducks came in half of the brown ducks flew away.

32/2=16 brown ducks left in the pond.

Lastly add the remaining brown ducks with the white ducks and that is you answer!
16+64=80 total amount of ducks

Final Answer:

80 ducks

Answer:

Step-by-step explanation:

For the expression to be negative (m + p) < 2.

An expression is a group of terms and mathematical symbols which can be evaluated to a given value.

Since we have the expression -2 + (m + p), we need to determine the value of (m + p) for which the value of the expression is negative.

This implies that the value of the expression is less than zero.

So, we proceed as follows.

Since the expression is -2 + (m + p), for it to be negative, it must be less than zero.

So, -2 + (m + p) < 0

⇒ -2 < -(m + p)

Dividing both sides by -1, we have that

-2/-1 < -(m + p)/-1

2 > (m + p)

(m + p) < 2

So, for the expression to be negative (m + p) < 2.

In each shape there are 4 wholes hence the answer is yes.

A fraction is referred to as the portion of a whole in mathematics. There are two components to a fraction: a numerator and a denominator. The numerator is the number at the top, and the denominator is the number at the bottom.

13a. There are 4 wholes, hence the answer is yes.

13b. Every whole is divided into 2 parts hence the total number of equal parts is 4 *2 = 8. Hence the answer is yes.

Step-by-step explanation:

Because this is a 45 to 45 degree triangle, the 3 * (square root of 2 )/2 is y as well. Because this is a 45-45 triangle, x should be y (Square root of 2).

The roots of the given quadratic equation are x = -2/3 and x = -2.

A quadratic equation is a equation that is of the form -

y = f{x} = ax² + bx + c

Given is a quadratic equation as follows -

3x² + 7 = - 8x + 3

The given quadratic equations are -

3x² + 7 = - 8x + 3

3x² + 8x = 3 - 7

3x² + 8x + 4 = 0

(x + 2/3)(x + 2) = 0

(x + 2/3) = 0   and   (x + 2) = 0

x = -2/3   and   x = -2    

Therefore, the roots of the given quadratic equation are x = -2/3 and x = -2.

The result of two Newton's technique iterations to approximation a function's zero using the provided starting guess is 1.5262!

Iteration describes carrying out a process repeatedly. To get a new value, start with an initial value and enter it into the iteration formula. To solve an equation using iteration, apply the new value for the subsequent substitution after that, and so on.

By Newton's Method, we have new guess of a zero of a function that are f(x), xn+1, and by using the previous guess, xn, like so-

xn+1 = xn - f(xn)/f'(xn)

and herethe case is [tex]f(x) = cos(x), and so f'(x) = -sin(x).[/tex]

Also, furthermore, [tex]cos(x)/(-sin(x)) = -cot(x).[/tex]

here, we have to simplify the formula to get a better guess for a zero to: xn+1 = xn + cot(xn)

[tex]x1 = 0.6, so x2 = 0.6 + cot(0.6) = 2.06170...\\And x3 = 2.06170... + cot(2.06170...) = 1.52615...\\Ans = 1.5262![/tex]
