x should equal -2 and y should equal -3 to solve this i multiplied the first equation by 2 then got rid of the 4y and -4y then i added the 14x to the 9 equaling 23x and added the -40 to the -6 which became 23x=-46 i solved this getting -s for x, then i plugged that into the equations to get y which was -3

Arianna kicks a soccer ball off the ground and into the air with an initial velocity of 42 feet per second. Assume the starting
beks73 [17]
A=g

v=⌠g dt

v=gt+C, where C=v initial

v=gt+vi

h=⌠v dt

h=gt^2/2+vit+C, where C=h initial

h=gt^2/2+vit+hi

We are told that vi=42 ft/s, hi=0, and we know g≈-32 ft/s^2 so

h(t)=-16t^2+42t

The ball will hit the ground when h=0 so

-16t^2+42t=0

-2t(8t-21)=0, since t>0

8t-21=0

8t=21

t=21/8

t=2.625 sec

t≈2.6 sec (to nearest tenth of a second)

The table shown below represents a function. Which of the following values could not be used to complete the table?
11111nata11111 [884]

Answer:

The answer to your question is: letter B

Step-by-step explanation:

Function definition: a function is a relation from a set of inputs to a set of outputs.

The most important about functions is that each input is related to one and only one output. Then there are not repeated values of inputs.

In the exercise, the inputs are -10, -25, -5, and the outputs are 5, 10, 15 and 20.

So, to solve this exercise, look for a number in the options that will not be repeated in the inputs,

Then,  

          - 20 is a possible option because is not repeated

           -5    is not an option to complete the table because 5 already exist.

          - 15 is a possible option because is not repeated previously.

In radian measure, the angles of a 45-45-90 triangle are:
jeka94

Answer:

The answer is the option A \frac{\pi}{4},\frac{\pi}{4},\frac{\pi}{2}

Step-by-step explanation:

we know that

The measure of \pi radians is equal to 180\°

so by proportion

Find the measure in radians of  45\°

\frac{\pi}{180}\frac{radians}{degrees}=\frac{x}{45}\frac{radians}{degrees}\\ \\x=(45/180)*\pi \\ \\x=\frac{\pi}{4}

Find the measure in radians of  90\°

\frac{\pi}{180}\frac{radians}{degrees}=\frac{x}{90}\frac{radians}{degrees}\\ \\x=(90/180)*\pi \\ \\x=\frac{\pi}{2}

therefore

In radian measure the angles are

\frac{\pi}{4},\frac{\pi}{4},\frac{\pi}{2}
