Answer:

y=x+6

Step-by-step explanation:

If you need to find a standard linear equation from two points, you have to first find the slope, then find the y intercept.

To find the slope, you should do the change in y over the change in x.

that would be:

(4-9)/(-2-3)

(-5)/(-5)

the slope is 1

plug that in along with values of x and y taken from known point (3,9) to the standard equation of a linear relationship:

y=mx+b

m=1

y=9

x=3

b=?

9=(1)(3)+b

9=3+b

b=6

The equation of the line would be y=x+6

Answer:

x - y = - 6

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Obtain the equation in slope- intercept form

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (3, 9)

m = [tex]\frac{9-4}{3+2}[/tex] = [tex]\frac{5}{5}[/tex] = 1, hence

y = x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 9), then

9 = 3 + c ⇒ c = 9 - 3 = 6

y = x + 6 ← equation in slope- intercept form

Subtract y from both sides

0 = x - y + 6 ( subtract 6 from both sides )

- 6 = x - y, thus

x - y = - 6 ← in standard form

NUMBER3

Step-by-step explanation:

Table no 3 is representing here a non-linear function.

A nonlinear function, as its name suggests, is a function that is not linear. In other words, the graph of a nonlinear function is not a line, its graph can be anything other than a line

Since a nonlinear function is a function that is not a linear, its equation can be anything that is not of the form f(x) = ax+ b. One examples of nonlinear functions is, f(x) = x2 is nonlinear as it is a quadratic function.

1. From the given right-triangle, the side opposite to [tex]\theta[/tex] is 6.8 units.

The adjacent side to [tex]\theta[/tex] is 4 units.

Recall the mnemonics, SOH-CAH-TOA.

We use the tangent ratio to obtain:

[tex]\tan \theta=\frac{Opposite}{Adjacent}[/tex]

[tex]\tan \theta=\frac{4}{6.8}[/tex]

[tex]\tan \theta=\frac{10}{17}[/tex]

[tex]\implies \theta=\tan^{-1}(\frac{10}{17})[/tex]

[tex]\implies \theta=30.5\degree[/tex] to the nearest tenth.

2. This time we were given the hypotenuse to be 15.7 units and the adjacent side is 6 units.

We use the cosine ratio to obtain:

[tex]\cos \theta=\frac{Adjacent}{Hypotenuse}[/tex]

[tex]\cos \theta=\frac{6}{15.7}[/tex]

[tex]\cos \theta=\frac{60}{157}[/tex]

[tex]\implies \theta=\cos^{-1}(\frac{60}{157})[/tex]

[tex]\implies \theta=67.5\degree[/tex] to the nearest tenth.

Answer:

25).  55.02°

26).  30.46°

Step-by-step explanation:

Points to remember

Trigonometric ratios

Sin θ  = Opposite side/Hypotenuse

Cos θ = Adjacent side/Hypotenuse

Tan θ = Opposite side/Adjacent side

To find the answer of question 25

Cos θ = Adjacent side/Hypotenuse

θ = Cos⁻¹(0.573) = 55.02°

To find the answer of question 26

Tan θ = Opposite side/Adjacent side

Step-by-step explanation:

well, she knows that the mass of chocolate is 1.8 times that of powered sugar.

it just so happen that powered sugar is 100 grams for one cup, and since chocolate is 1.8 times "that", then in one cup of chocolate there must be 1.8 times 100 grams, or 1.8*100 = 180 grams.

the recipe uses 1/2 cup of chocolate, well, half a cup of chocolate, namely half of 180 grams is just 90 grams.

The statement -11 is greater than -3, so it was colder in Milwaukee is true.

Answer:

-11 is greater than -3, so it was colder in Milwaukee.

Step-by-step explanation:

Answer 1 (-11 is greater than -3, so it was colder in Chicago) is incorrect because it was -3 in Chicago, not -11.

Answer 2 (-3 is greater than -11, so it was colder in Chicago) is incorrect because -3 is not greater than -11.

Answer 3 is correct because -11 is greater than -3 and the cities are labeled correctly.

Answer 4 (-3 is greater than -11, so it was colder in Milwaukee) is incorrect because -3 is not greater than -11. Milwaukee was also -11, not -3.

The correct answer is C

EXPLANATION

The given triangle is a right triangle. Since two angles are equal, it is a right isosceles triangle.

This implies that, x=8 units.

Using Pythagoras Theorem,

[tex] {y}^{2} = {8}^{2} + {8}^{2} [/tex]

This implies that:

[tex]{y}^{2} = 64 + 64[/tex]

[tex]{y}^{2} =128[/tex]

Take positive square root,

[tex]{y} = \sqrt{128} [/tex]

[tex]{y} = 8 \sqrt{2} [/tex]

The correct answer is C

Answer:

Correct choice is C. [tex]x=8[/tex], [tex]y=8\sqrt{2}[/tex].

Step-by-step explanation:

Apply formula [tex]\sin\left(\theta\right)=\frac{opposite}{hypotenuse}[/tex]

[tex]\sin\left(45^o\right)=\frac{8}{y}[/tex]

[tex]\frac{1}{\sqrt{2}}=\frac{8}{y}[/tex]

[tex]y=8\sqrt{2}[/tex]

Apply formula [tex]\tan\left(\theta\right)=\frac{opposite}{adjacent}[/tex]

[tex]\tan\left(45^o\right)=\frac{8}{x}[/tex]

[tex]1=\frac{8}{x}[/tex]

Answer:

1/4 is the original length

Step-by-step explanation:

The original length of the rectangle is 11/72 square feet. To get the area of a rectangle, you multiply the length x width.

You already know the width in this problem. The width is 1/6 feet. So, divide the area (11/72 feet) by the width (1/6 feet) to get the length, 11/12 feet.

However, the original length was increased by 2/3 feet. So, take our new length (11/12 feet) and subtract the increased length (2/3 feet) from it. When you do that, you get 1/4 feet.

Therefore, the answer is 1/4 feet. Hope this helps! :)

ANSWER

The water arc is 50 ft above the water approximately 42ft and 158ft from the north shore.

EXPLANATION

The water arc is modeled by the function:

[tex]y = - 0.006 {x}^{2} + 1.2x + 10[/tex]

We write this function in vertex form:

[tex]y = - 0.006 ({x}^{2} - 200x )+ 10[/tex]

[tex]y = - 0.006 ({x}^{2} - 200x + ( - 100)^{2} ) - - 0.006( - 100)^{2} + 10[/tex]

[tex]y = - 0.006 ( x- 100)^{2} ) + 60+ 10[/tex]

[tex]y = - 0.006 ( x- 100)^{2} ) +70[/tex]

The vertex of this function is at

(100,70).

This means that the water arc reached a height of 50ft.

We put y=50 and solve for x.

[tex]- 0.006 ( x- 100)^{2}+70 = 50[/tex]

[tex]- 0.006 ( x- 100)^{2} = - 20[/tex]

[tex]( x- 100)^{2} = \frac{10000}{3} [/tex]

[tex]x = 100 \pm \frac{100 \sqrt{3} }{3} [/tex]

x=42.3 or x=157.7

Hence the water arc is 50 ft above the water approximately 42ft and 158ft from the north shore.

The water arc does reach a height of 50 feet, and it is about 42.27 feet and 157.73 feet from the north shore when it is 50 feet above the water.

1.Set up the equation:

[tex]\[ -0.006x^2 + 1.2x + 10 = 50 \][/tex]

2. Simplify the equation:

Subtract 50 from both sides:

[tex]\[ -0.006x^2 + 1.2x + 10 - 50 = 0 \] \[ -0.006x^2 + 1.2x - 40 = 0 \][/tex]

3. Solve the quadratic equation:

We can use the quadratic formula

[tex]\( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \), where \( a = -0.006 \), \( b = 1.2 \), and \( c = -40 \).[/tex]

[tex]\[ a = -0.006, \quad b = 1.2, \quad c = -40 \][/tex]

[tex]\[ \Delta = b^2 - 4ac \] \[ \Delta = 1.2^2 - 4(-0.006)(-40) \] \[ \Delta = 1.44 - 0.96 \] \[ \Delta = 0.48 \][/tex]

[tex]\[ x = \frac{-b \pm \sqrt{\Delta}}{2a} \] \[ x = \frac{-1.2 \pm \sqrt{0.48}}{2(-0.006)} \][/tex]

Calculate the square root of 0.48:

[tex]\[ \sqrt{0.48} \approx 0.6928 \][/tex]

  Now, find the two values of x:

[tex]\[ x_1 = \frac{-1.2 + 0.6928}{-0.012} = \frac{-0.5072}{-0.012} \approx 42.27 \] \[ x_2 = \frac{-1.2 - 0.6928}{-0.012} = \frac{-1.8928}{-0.012} \approx 157.73 \][/tex]

Therefore, the water arc reaches a height of 50 feet at approximately [tex]\( x = 42.27 \) feet and \( x = 157.73 \)[/tex] feet from the north shore.
