Answer:

$a = 8.5t$

$y = 32.55$

Step-by-step explanation:

Solving (9): The equation of the table

We start by calculating the slope (m)

$m = \frac{a_2 - a_1}{t_2 - t_1}$

Where:

$(t_1,a_1) = (15,127.5)$

$(t_2,a_2) = (16.5,140.25)$

$m = \frac{140.25 - 127.5}{16.5 - 15}$

$m = \frac{12.75}{1.5}$

$m = 8.5$

The equation is then calculated using:

$a = m(t - t_2) + a_2$

So, we have:

$a = 8.5(t - 16.5) + 140.25$

Open bracket

$a = 8.5t - 140.25 + 140.25$

$a = 8.5t$

Solving (10):

$4.8y = 156.24$

Required

Find x

Divide both sides by 4.8

$y = 32.55$

A traditional postage stamp has a width of 4/5 inches and a length of 9/10. What is the area of a traditional postage stamp?

Illusion [34]

4/5*9/10= 36/50 = 18/25

Just multiply the fractions straight across since area is length*height

Give an example of a set of five ordered pairs. Determine the domain and range of the set.

sergey [27]

DOMAIN:

Set of allowable inputs (set of 1st elements of the ordered pairs in relation)
X point
AKA the input

DEFINE INPUT:

A number that'll be used in a function rule to determine the value of the output

RANGE:

Set of possible outputs (set of 2nd elements of the ordered pairs in relation)
Y point
AKA the output

DEFINE OUTPUT:

Result of applying a function rule to the value of ani input

ORDERED PAIRS:

(-1, 7): -1 is the domain & 7 is the range

(3, 5): 3 is the domain & 5 is the range

(4, 9): 4 is the domain & 9 is the range

(-6, -10): -6 is the domain & -10 is the range

(-2, 8): -2 is the domain & 8 is the range

Hope this helps you!!! :)

A triangle has side lengths of (1.3f+2.9g)(1.3f+2.9g) centimeters, (1.1f-7.7h)(1.1f−7.7h) centimeters, and (2.3h+1.5g)(2.3h+1.5g

VikaD [51]

Answer:

Perimeter of the triangle = (2.4f+4.4g-5.4h) centimeters.

Step-by-step explanation:

It is given that, a triangle has side lengths of (1.3f+2.9g) cm, (1.1f-7.7h)cm, and (2.3h+1.5g) cm.

We have to find the expression which represents the perimeter, in centimeters, of the triangle.

Perimeter of a triangle = Sum of its all the sides.

$Perimeter=(1.3f+2.9g)+(1.1f-7.7h)+(2.3h+1.5g)$

On combining like terms, we get

$Perimeter=(1.3f+1.1f)+(2.9g+1.5g)+(-7.7h+2.3h)$

$Perimeter=2.4f+4.4g+(-5.4h)$

$Perimeter=2.4f+4.4g-5.4h$

Therefore, the perimeter of the triangle is (2.4f+4.4g-5.4h) centimeters.
