Answer:

Step-by-step explanation:

Here,

Height's are - 12 , 35 and 60

Ages are- 3 , 7 , 10

Now, the ratios of height to age are -

$\frac{12}{3}=4 ; \frac{35}{7}=5 ;\frac{60}{10}=6$

So, we can see that-

the ratios of height to age are not equal.

For different ratio, we get different result.

Since, the ratio of height to ages are not equal.

So,

Height is not proportional to age.

Yes because it’s 4,5,6. At least that is what I believe so. I may be wrong

Delicious77 [7]

Answer:the height of the balloon is 670.244 feet

Step-by-step explanation:

The right angle triangle BLD represents the scenario.

h represents the height of the balloon.

We would apply trigonometric ratio to determine h.

Tan # = opposite side/adjacent side

Looking at triangle LCD,

# = 61 degrees

h = opposite side

x = adjacent side

Tan 61 = h/x

1.7321 = h/x

h = 1.7321x

Looking at triangle LBD,

# = 54 degrees

h = opposite side

x + 100 = adjacent side

Tan 54 = h/x + 100

1.3764 = h/x + 100

h = 1.3764(x + 100)

Therefore,

1.7321x = 1.3764(x + 100)

1.7321x = 1.3764x + 137.64

137.64 = 1.7321x - 1.3764x

137.64 = 0.3557x

x = 137.64/0.3557 = 386.955

h = 1.7321x = 386.955 × 1.7321

h = 670.244 feet

Is the relationship shown by the data linear? If so, model the data with an equation.

Harrizon [31]

The <u>correct answer</u> is:

The relationship is linear, and the equation is
y-5 = 2(x+7).

Explanation:

To determine if the relationship is linear, we find the slope between each pair of points. Slope is given by the formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

The slope between the <u>first two points</u> is given by:

$m=\frac{9-5}{-5--7}=\frac{9-5}{-5+7}=\frac{4}{2}=2$

The slope between the <u>second pair of points</u> is given by:

$m=\frac{13-9}{-3--5}=\frac{13-9}{-3+5}=\frac{4}{2}=2$

The slope between the <u>third pair of points</u> is given by:

$m=\frac{17-13}{-1--3}=\frac{17-13}{-1+3}=\frac{4}{2}=2$

Since the <u>slope is the same</u> throughout the data, the <u>relationship is linear</u> and the slope is 2.

To write the equation, we use point-slope form, which is:

y-y₁ = m(x-x₁)

Using the first point, we have:

y-5 = 2(x--7)
y-5 = 2(x+7)
