Answer:

A. x²+x-11

Step-by-step explanation:

Take one of the x values and try them out on all formulas to see if the expected output occurs.

Already with x=2 you get

-5, 28, -3, 27 so you know that only the first formula works.

It is 42 1/2 miles from Eaton to Baxter, and 37 4/5 miles from Baxter to Wellington. How far is it from Eaton to Wellington, if

IgorC [24]

$42 \frac{1}{2} + 37 \frac{4}{5}$

$42 \frac{5}{10} + 37 \frac{8}{10}$

$\frac{5}{10} + \frac{8}{10} = \frac{13}{10} = 1 \frac{3}{10}$

$79 + 1 \frac{3}{10} = 80 \frac{3}{10}$

$80 \frac{3}{10} \: \:miles \: or \: 80.3 \: miles$

Just double check that I did the right calculations

The path of a projectile launched from a 26-ft-tall tower is modeled by the equation y = −16t2 + 64t + 26. What is the maximum h

BabaBlast [244]

Answer:

The maximum height of the projectile is 90 ft

Step-by-step explanation:

Here, we want to get the maximum height reached by the projectile

The answer here will be the y-coordinate value of the vertex form of the given equation

so firstly, we have to write the equation in the vertex form

We have this as;

y = -16t^2 + 64t + 26

That will be;

y = a(x-h)^2 + k

y = -16(x-2)^2 + 90

where the vertex of the equation is;

(-h,k)

in this case is 90 and thus, that is the maximum height of the projectile

Graph the line with slope 3/2 and y-intercept 3.

Tcecarenko [31]

Answer:

The steepness of any incline can be measured as the ratio of the vertical change to the horizontal change. For example, a 5 % incline can be written as 5100 , which means that for every 100 feet forward, the height increases 5 feet.Figure 4.4.1 In mathematics incline of a line the slope and use the letter m to denote it. The vertical change is called the rise and the horizontal change is called the run.Slopem=vertical changehorizontal change=riserun(4.4.1)The rise and the run can be positive or negative. A positive rise corresponds to a vertical change up and a negative rise corresponds to a vertical change down. A positive run denotes a horizontal change to the right and a negative run corresponds to a horizontal change to the left. Given the graph, we can calculate the slope by determining the vertical and horizontal changes between any two points.Example 4.4.1 Figure 4.4.2 From the given points on the graph, count 3 units down and 4 units right.m=riserun=−3units4units=−34 the Answer is.m=−34 .
