Linear relationship always produces a straight line and are without exponential.

Lets check all the given options:

1. the total area, in square meters, y, of a square garden if the side length is x meters.

The area of a square is [tex](side)^{2}[/tex]

Here, side is 'x' and area 'y' will be [tex]x^{2}[/tex].

This is not linear.

2. the height, y, of a 6-foot tree that grows 0.2 feet per month for x months

The equation forms:

[tex]y=6+0.2x[/tex]

When x = 1

[tex]y=6.2[/tex]

When x = 2

[tex]y=6+0.2(2)[/tex]

=> [tex]y=6.4[/tex]

When x = 3

[tex]y=6+0.2(3)[/tex]

=> [tex]y=6.6[/tex]

This is a linear relation.

3. the total cost, y, of a ski rental from a company that charges $15 plus an additional $8 per day rented for x days

The equation forms:

[tex]y=15+8x[/tex]

When x = 1

[tex]y=15+8=23[/tex]

When x = 2

[tex]y=15+8(2)[/tex]

=> [tex]y=31[/tex]

When x = 3

[tex]y=15+8(3)[/tex]

=> [tex]y=39[/tex]

This is also linear.

4. the total miles, y, traveled by a car going 62 miles per hour in x hours

The equation forms:

[tex]y=62x[/tex]

When x = 1

[tex]y=62[/tex]

When x = 2

[tex]y=62(2)[/tex]

=> [tex]y=124[/tex]

When y = 3

[tex]y=62(3)[/tex]

=> [tex]y=186[/tex]

This is also linear in nature.

Answer:

D)y-intercept of f(x) is greater than the y-intercept of g(x)

Step-by-step explanation:

Y-intercept is the point y-coordinate value on graph where graph line intersects the y-axis and the value of x coordinate on x-axis is zero at that point.

From the given graph of f(x), it can be seen that

y-intercept of f(x) is 2

For the given function g(x)

finding y-intercept

when x=0

y=-3

because g(x) = 3 for 1<x≤3

As 2>-3

hence y-intercept of f(x)>g(x) !

Answer:

Perfect positive association

Step-by-step explanation:

Definition: A perfect positive association means that a relationship appears to exist between two variables, and that relationship is positive 100% of the time. Two variables have a positive association when the values of one variable tend to increase as the values of the other variable increase. (+1 indicates a perfect positive linear relationship)

Definition: A perfect negative association means that a relationship appears to exist between two variables, and that relationship is negative 100% of the time. Two variables have negative association when the values of one variable tend to decrease as the values of the other variable increase. (-1 indicates a perfect negative linear relationship)

Values between 0.3 and 0.7 (-0.3 and -0.7) indicate a moderate positive (negative) linear relationship.

From the graph we can see that this relationship shows perfect positive association (both variables increase and we can plot the straight line which will include all points)

Answer:

Answer:

The equation would be:

(X+1)^2 + (y-1)^2 = 9

This is the equation of the circle in general form.  

[tex]\[ x^2 + y^2 + 2x - 2y - 7 = 0 \][/tex]

or

[tex]\[ (x + 1)^2 + (y - 1)^2 = 9 \][/tex]

To write the equation of a circle in general form, you start with the standard form of the circle's equation, which is:

[tex]\[ (x - h)^2 + (y - k)^2 = r^2 \][/tex]

where \( (h, k) \) is the center of the circle and \( r \) is the radius.

From the information provided:

- The center of the circle is \( (-1, 1) \)

- The radius of the circle is \( 3 \) units

Let's substitute these values into the standard form:

[tex]\[ (x - (-1))^2 + (y - 1)^2 = 3^2 \][/tex]

[tex]\[ (x + 1)^2 + (y - 1)^2 = 9 \][/tex]

Now, to write it in general form, you'll expand the equation and combine like terms:

Step 1: Expand the squares

[tex]\[ (x + 1)^2 = x^2 + 2x(1) + 1^2 \][/tex]

[tex]\[ (y - 1)^2 = y^2 - 2y(1) + 1^2 \][/tex]

Step 2: Write the expanded form

[tex]\[ x^2 + 2x + 1 + y^2 - 2y + 1 = 9 \][/tex]

Step 3: Combine like terms

[tex]\[ x^2 + y^2 + 2x - 2y + 1 + 1 = 9 \][/tex]

Step 4: Move the constant to the right side

[tex]\[ x^2 + y^2 + 2x - 2y = 9 - 2 \][/tex]

Step 5: Final general form

[tex]\[ x^2 + y^2 + 2x - 2y - 7 = 0 \][/tex]

This is the equation of the circle in general form.

Answer:

The measure of angle FGH is m∠FGH=48°

Step-by-step explanation:

step 1

Find the measure of arc FG in terms of x

we know that

The inscribed angle measures half that of the arc comprising

m∠FHG=(1/2)[arc FG]

substitute the given values

(28x−3°)=(1/2)[arc FG]

arc FG=(56x−6°)

step 2

Find the value of x

we know that

arc FG+arc FH+arc GH=360° -----> by complete circle

substitute the values

(56x−6°)+(31x+3°)+ (33x+3°)=360°

120x=360°

x=3°

step 3

Find the measure of angle m∠FGH

we know that

The inscribed angle measures half that of the arc comprising

m∠FGH=(1/2)[arc FH]

substitute the given values

m∠FGH=(1/2)[31x+3°]

m∠FGH=(1/2)[31(3)+3°]

m∠FGH=48°

Answer:

Good day! Use trigonometry to define the formula.

Step-by-step explanation:

The height of the tree that the sun appears just over it top is 12 meters

The situation forms a right angle triangle.

The height of the tree is the opposite side of the triangle.

His distance away from the base of the tree is the adjacent side of the right angle triangle.

Therefore,

Using trigonometric ratio,

tan 32 = opposite / adjacent

tan 32 = h / 20

cross multiply

height of the tree = 20 tan 32

height of the tree = 20 × 0.6248693519

height of the tree = 12.4973870382

height of the tree ≈ 12 meters

Step-by-step explanation:

For an equation of the form [tex]ax^2 +bx +c[/tex]

The quadratic formula is

[tex]\frac{-b\±\sqrt{b^2 -4ac}}{2a}[/tex]

In this case the equation is:

[tex]2x^2 - 10x + 7 = 0[/tex]

Then

[tex]a= 2\\b= -10\\c= 7[/tex]

Therefore, using the quadratic formula we have:

[tex]x=\frac{-(-10)\±\sqrt{(-10)^2 -4(2(7)}}{2(2)}[/tex]

[tex]x=\frac{5\±\sqrt{11}}{2}[/tex]

[tex]x_1=4.158[/tex]

ANSWER

[tex]x = \frac{ 5 }{2} - \frac{\sqrt {11} } {2} \: or \: x = \frac{ 5 }{2} + \frac{\sqrt {11} } {2} [/tex]

EXPLANATION

The given quadratic equation is:

[tex] 2{x}^{2} - 10x + 7 = 0[/tex]

Comparing this equation to

[tex] a{x}^{2} + bx + c = 0[/tex]

we have

a=2, b=-10 and c=7.

The solution is given by the quadratic formula;

[tex]x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac } }{2a} [/tex]

We plug in the values to get,

[tex]x = \frac{ - - 10 \pm \sqrt{ {( - 10)}^{2} - 4(2)(7) } }{2(2)} [/tex]

This implies that

[tex]x = \frac{ 10 \pm \sqrt{ {100} - 56 } }{4} [/tex]

[tex]x = \frac{ 10 \pm \sqrt {44 } }{4} [/tex]

[tex]x = \frac{ 10 \pm 2\sqrt {11 } }{4} [/tex]

[tex]x = \frac{ 5 \pm \sqrt {11 } }{2}[/tex]

[tex]x = \frac{ 5 }{2} - \frac{\sqrt {11} } {2} \: or \: x = \frac{ 5 }{2} + \frac{\sqrt {11} } {2} [/tex]

For this case we have that by definition, the Pythagorean theorem states that:

[tex]c = \sqrt {a ^ 2 + b ^ 2}[/tex]

Where:

a, b: Are the legs

c: It is the hypotenuse

According to the figure we have to:

[tex]a = 20\\b = 21[/tex]

Substituting in the formula we have:

[tex]c = \sqrt {(20) ^ 2 + (21) ^ 2}\\c = \sqrt {400 + 441}\\c = \sqrt {841}\\c = 29[/tex]

y = 23

Step-by-step explanation:

The diagonals of a rhombus are perpendicular bisectors of each other, thus

∠1 = 90° and ∠1 = 4y - 2, so equating gives

4y - 2 = 90 ( add 2 to both sides )

4y = 92 ( divide both sides by 4 )

y = 23

For x = -2, y = (-2)² -2 ⇒  y = 4 - 2  ⇒  y = 2

For x = -1, y = (-1)² -2 ⇒  y = 1 - 2  ⇒  y = -1

For x = 0, y = (0)² -2 ⇒  y = 0 - 2  ⇒  y = -2

For x = 1, y = (1)² -2 ⇒  y = 1 - 2  ⇒  y = -1

For x = 2, y = (2)² -2 ⇒  y = 4 - 2  ⇒  y = 2

Answer:

x = 14

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value of sin45°

sin45° = [tex]\frac{\sqrt{2} }{2}[/tex]

Hence

sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{7\sqrt{2} }{x}[/tex]

Multiply both sides by x

x × sin45° = 7[tex]\sqrt{2}[/tex] ( divide both sides by sin45° )

x = [tex]\frac{7\sqrt{2} }{sin45}[/tex]

  = [tex]\frac{7\sqrt{2} }{\frac{\sqrt{2} }{2} }[/tex]

  = 7[tex]\sqrt{2}[/tex] × [tex]\frac{2}{\sqrt{2} }[/tex] = 7 × 2 = 14
