You notice a hot air balloon ascending. The elevation h (in feet) of the balloon is modeled by the function h (x) = 6x + 90, where x is the time (in seconds) since you first noticed the hot air balloon.
Graph the function and specify its domain and range. Then interpret the slope and intercept of the
graph.

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation y = Kx also represents direct proportionality. Here, K is called constant of proportionality. It is same as slope.
Given is the elevation [h] (in feet) of the balloon which is modeled by the function h(x) = 6x + 90, where [x] is the time (in seconds) since you first noticed the hot air balloon.
We have the following equation -
y = 6x + 90
Refer to the graph attached.
The line passes through the points (-15, 0) and (0, 90). So, the slope of the line will be -
m = 90/15
m = 6
AND
[y] - intercept will be 90.
Domain → (0, ∞) and range → (0, ∞) for ideal situations.
Therefore, the slope of the line will be 6 and its [y] - intercept will be 90.

How to interpret integral multiplication?Suppose that there are two positive integer numbers( numbers like 1,2,3,.. ) as a and b
Then, their multiplication can be interpreted as:
[tex]a \times b = a + a + ... + a \: \text{(b times)}\\\\a \times b = b + b +... + b \: \text{(a times)}[/tex]
For example,
[tex]5 \times 2 = 10 = 2 + 2 + 2 + 2 + 2 \: \text{(Added 2 five times)}\\or\\5 \times 2 = 10 = 5 + 5 \: \text{(Added 5 two times)}[/tex]
Given;
From 100 to 10^6;
100 * 10^4 = 10^6
From 100 to 90;
100/10*9=90
From 90 to 100
90/9*10=100
From 10^6 to 100
10^6/10^4=100
Therefore, by multiplication or division will be 10^6/10^4

A car traveling at 45 ft/sec decelerates at a constant 7 feet per second squared. How many feet does the car travel before coming to a complete stop
Answer:
s = 144.64 feet
Step-by-step explanation:
Given that,
The initial speed of a car, u = 45 ft/s
Deacceleration of the car, a = -7 m/s²
We need to find the distance covered by the car travel before coming to a complete stop. let it is d.
Final velocity, v = 0
Using the third equation of motion as follows :
[tex]v^2-u^2=2as\\\\s=\dfrac{v^2-u^2}{2a}\\\\s=\dfrac{0^2-45^2}{2\times (-7)}\\\\s=144.64\ \text{feet}[/tex]
So, it will cover a distance of 144.64 feet.
Consider the equation 2y - 4x = 12
Which equation, when graphed with the given equation, will form a system with Infinitely many solutions?
-y-2x = 6
-y=2x = 12
y=2x+6
y=2x + 12
Answer:
y = 2x + 6 and 2y-4x=12 are the same line, so have infinitely many solutions.
Step-by-step explanation:
2y - 4x = 12
This is the same as y = 2x + 6
The solution is Option C.
The value of the equation is y = 2x + 6
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
2y - 4x = 12 be equation (1)
On simplifying the equation , we get
Adding 4x on both sides of the equation , we get
2y = 4x + 12
Divide by 2 on both sides of the equation , we get
y = 2x + 6

compare the fraction 3/5 to 1/2
Answer:
1 / 2 is smaller than 3 / 5.
Step-by-step explanation:
Compare 1/2 and 3/5. 1 / 2 is smaller than 3 / 5. Steps for comparing fractions. Find the least common denominator or LCM of the two denominators: LCM of 2 and 5 is 10; For the 1st fraction, since 2 × 5 = 10, 1 / 2 = 1 × 5 / 2 × 5 = 5 / 10; Likewise, for the 2nd fraction, since 5 × 2 = 10, 3 / 5 = 3 × 2 / 5 × 2 = 6 / 10 Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction
