What is the difference between the ordered pairs

2 answers:

Nataly [62]4 years ago

When an ordered pair is in a shared region it means that the ordered pair is a solution to the inequality.
If an ordered pair is on the line of an inequality, it may or may not be a solution. If the inequality is a ≤ ≥ then the point on the line will be a solution because the line is part of the solution. If the inequality is a > < then the point t on the line will not be a solution because the line is not part of the solution.

Joseph jumped off of a cliff into the ocean in Miami while vacationing with some friends. His height as a function of time is gi

Aneli [31]

Answer:

Step-by-step explanation:

I think the missing equation in your question is: h(t) = -16 $t^{2}$ + 16t + 480

Here is my answer:

As we know that the vertex form of a parabola, y=a $(x-h)^{2}$ + k where(h,k) is the vertex

h(t) = -16 $t^{2}$ + 16t + 480

= -16 ( $t^{2} -t)$ + 480

= -16 $(t-\frac{1}{2}) ^{2}$ + 484

So the vertex is ( $\frac{1}{2}$ , 484)

a. It take for Joseph $\frac{1}{2}$ second to reach his maximum height

b. The highest point that Joseph reached is the vertex of the function, it is 484 ft

c. Joseph hit the water after how many seconds?

<=> h(t) = 0

<=> -16 $t^{2}$ + 16t + 480 = 0

<=> t = $\frac{192}{32}$ second = 6 sec

Hope it will find you well

Find the angle θ, in radians, in the second quadrant whose tangent is -2.

ololo11 [35]

In order to find the angle θ, in <u>radians</u>, whose<u> tangent</u> is $-2$ you have to follow those steps

Step 1

Using a<u> calculator</u>

Find the angle θ

$Angle=arc\ tan(-2)= -63.43\°$

Remember that

the angle θ belong to the second quadrant

so

Angle θ= $180\°-63.43\°=116.57\°$

Step 2

Convert degrees to <u>radians</u>

we know that

$\pi\ radians=180\°$

$116.57\°=116.57\°*\pi/180\°=0.648\pi\ radians$

therefore

the answer is

the angle θ is $0.648\pi\ radians$

Which equation matches the graph of the greatest integer function given

bekas [8.4K]

The equation that matches the graph of the greatest integer function is y = [x] - 2

<h3>How to determine the equation?</h3>

The parent function of an step function is represented as:

y = [x]

From the given graph, we can see that the lines are shifted 2 units down.

This means that:

(x,y) = (x,y - 2)

So, we have:

y = [x] - 2

Hence, the equation that matches the graph of the greatest integer function is y = [x] - 2

A blueprint scale is 1/4 in=1ft. If the blueprint measurement is 2in x 1in, what should you cut?

emmainna [20.7K]

8ft by 4ft.

This is because there are 8/4 and 4/4 to make up the blueprint. Therefor you have to multiply the factor by 8 and 4.

solmaris [256]

Answer: £30.31

Explanation:

100/140 minutes of calls were free. Then, 40 x .09, which is 3.6

61 non-free texts, costing 11p each. So... 61 x .11 = 6.71

Add those together, with 20.
