Travka [436]

Answer:

$7.5\ seconds$

Step-by-step explanation:

The Equation of motion is given by

$v=u-at\\\\\ v:Final\ Velocity\\u:Initial\ Velocity\\a:acceleration\\t:time$

Here $v=0(as\ at\ the\ end\ car\ stops), u=30m/s,a=-4m/s^2$

$0=30-4t\\\\4t=30\\\\t=\frac{30}{4}\\\\t=7.5\ seconds$

The ratio of boys to girls at the dance was 8 to 4. How many girls were at the dance if there were 88 boys at the dance?

nevsk [136]

88/8=11.

So multiply 4 by 11.

4x11=44

So the ratio is 88:44.

There are 44 girls at the dance

Answer:

y=-3x+4

Step-by-step explanation:

im assuming that you need the equation of the table

to find slope, y2-y1/x2-x1 10-4/-2-0

6/-2=-3 slope=-3

y=mx+b just sub in the numbers from a point in the table

10=-3(-2)+b

10=6+b

b=4

y=-3x+b

(Look at the pic) what is FC?

Hitman42 [59]

The element on the position (1,1) in the product matrix FC is a scalar product of the first row in F and the first column in C.

Therefore the element in the position (1,1) in FC will be a scalar product of (-2,0) and (12,1):

$-2\cdot 12+0\cdot 1 = -24+0=-24$

The only matrix that has a value of -24 in the position (1,1) is matrix B.

Therefore, the answer is matrix B.
