gertie had a uniform speed till 17 cm/s and the had a decrease in its velocity ... and finally got back to its initial velocity...

harold was increasing its velocity from rest and then took rest after 15 metres and then again moved with an increasing velocity after 40 seconds

For what values of m does the graph of y = 3x2 + 7x + m have two x-intercepts

Irina18 [472]

we are given

$y=3x^2+7x+m$

To find x-intercept means we have to find zeros

and for finding zeros , we will use quadratic formula

and we have it has two x-intercepts

so, it's discriminant must be greater than 0

so, we will find discriminant

$D=\sqrt{b^2-4ac}$

now, we can compare with

$y=ax^2+bx+c$

$y=3x^2+7x+m$

and then we can find a , b and c

$a=3,b=7,c=m$

now, we can find D

$D=\sqrt{7^2-4*3*m}$

$D=\sqrt{49-12m}$

It has two x-intercepts

so,

$D=\sqrt{49-12m}>0$

now, we can solve for m

$49-12m>0$

$12m$

In a class there are 40 students 30 are boys and what is the percentage of girls ....

Artyom0805 [142]

Answer:

25%

Step-by-step explanation:

Total= 40 students

boys +girls= 40

30 +girls= 40

number of girls

= 40 -30

= 10

Percentage of girls

$= \frac{10}{40} \times 100\% \\ = 25\%$

Alternatively,

percentage of girls

= 100% -(percentage of boys)

$= 100\% - ( \frac{30}{40} \times 100\%) \\ = 100\% - 75\% \\ = 25\%$

jeanette wants to tile the floor of a room in her house. the square tiles measure 3/4 ft on each side. the room is 10 ft wide. w

Yuri [45]

First off i dont like using fractions so i will convert 3/4 into 0.75 to start. Then i would divide 0.75 into 10 and that equals 13 and 1/3

The answer is 13 tiles and 1/3 of a tile to make one row

Identify the surface with the given vector equation. r(u, v) = 2 sin(u) i + 5 cos(u) j + v k, 0 ≤ v ≤ 5 plane hyperbolic parabol

olchik [2.2K]

Note that this just produces three parametric equations:

$x(u) = 2 \sin(u)$
$y(u) = 5 \cos(u)$
$z(v) = v$

In the $x-y$ plane, this is just he parametric equation for an ellipse (as a function of u). The z is simply a linear function.

The surface is then an ellipse extruded along the z-axis. We get a elliptic cylinder.
