Answer:

105 frames

Step-by-step explanation:

Given that 25 frames are played per second

25 frames= 1 sec

The video already played 3 and 2/5 seconds before the player started to count 0

Write 3 and 2/5 seconds as an improper fraction

=(5*3)+2 / 5 = 17/5 seconds

Multiply by 25 frames

17/5 *25 =85 frames

So according to the video counter,after 17/5 seconds,it should count 85 frames.However,at 0 seconds,it indicated a count of 190 frames.Thus,to get the number of frames that were already in count you subtract 85 frames from the 190 frames.

190-85=105 frames.

Answer:

The number of frames when the time was equal to -3\frac{2}{5} seconds is 125.

Step-by-step explanation:

It is given that the player began counting at 0 seconds, even though the video had already played 190 frames. The video plays 25 frames per second.

The slope intercept form of linear function is

y=mx+b

where, m is rate of change and b is initial value.

It means the initial number of frames = 190

Change in frames per second = 25

The equation that represents the number of frames after x seconds is

y=25x+190            .... (1)

We need to find the number of frames when the time was equal to -3\frac{2}{5} seconds.

x=-3\frac{2}{5}=-\frac{13}{5}

Substitute x=-\frac{13}{5} in equation (1),

y=25(-\frac{13}{5})+190

y=-65+190

y=125

Therefore the number of frames when the time was equal to -3\frac{2}{5} seconds is 125.

Evaluate g(x) = x2 + 5 given the inputs (-1,0,1,2}
mihalych1998 [28]

Answer:

g(-1) = 6

g(0) = 5

g(1) = 6

g(2) = 9

Step-by-step explanation:

Step 1: Plug in -1 for <em>x</em>

g(-1) = (-1)² + 5

g(-1) = 1 + 5

g(-1) = 6

Step 2: Plug in 0 for <em>x</em>

g(0) = 0² + 5

g(0) = 0 + 5

g(0) = 5

Step 3: Plug in 1 for <em>x</em>

g(1) = 1² + 5

g(1) = 1 + 5

g(1) = 6

Step 4: Plug in 2 for <em>x</em>

g(2) = 2² + 5

g(2) = 4 + 5

g(2) = 9

{4x+2y=10<br> y=2x-1<br><br>What is the value of x+y<br><br>A.3.125<br>B.2<br>C.4.5<br>D.3.5​
Evgen [1.6K]

Answer:

D.3.5

Step-by-step explanation:

4x+2y=10(given)

2x+y=5

y=5-2x-----(1)

y=2x-1------(2)(given)

Since the left side of the equations are the the same,

5-2x=2x-1

4x=6

x=1.5

Sub x=1.5 into eq(1),

y = 5-2(1.5) = 5-3 = 2

so, x+y = 1.5+2 = 3.5
