How do you do question b?

notsponge [240]

Part (b)

We use the result of part (a) and plug in (x,y) = (0,0). This is directly from the initial condition y(0) = 0.

$\arcsin(4y) = x^2 + C\\\\\arcsin(4*0) = (0)^2 + C\\\\\arcsin(0) = C\\\\0 = C\\\\C = 0\\\\$

-----------------

This means,

$\arcsin(4y) = x^2 + C\\\\\arcsin(4y) = x^2 + 0\\\\\arcsin(4y) = x^2\\\\4y = \sin(x^2)\\\\y = \frac{1}{4}\sin(x^2)\\\\$

is the solution with the initial condition y(0) = 0.

If 3220 = 80+7, what is the value of c?

Setler79 [48]

Answer:

Correct option is

36.25

Modal class =30−40

So we have, l=30,f0=12,f1=32,f2=20 and h=10

⇒ Mode=l+2f1−f0f2f1−f0×h

=30+2×32−12−2032−12×10

=30+6.25

=36.25

∴ Mode =36.25

Richie and bethany play basketball and practice shooting free throws after school. During one practice session, Richie attempted

mamaluj [8]

Answer:

<em>Bethany did not do better than Richie because her average score was less than his.</em>

Step-by-step explanation:

<u>Average Value</u>

The average or mean value of m successes out of n tries is given by:

$\displaystyle \bar x=\frac{m}{n}$

During a practice session playing basketball, Richie made m=12 free throws from n=15 attempts. His average score was:

$\displaystyle \bar x=\frac{12}{15}=0.8$

Bethany made 8 free throws for every 3 that she missed, this means she made 8 out of 11 attempts. Her average score was:

$\displaystyle \bar x=\frac{8}{11}=0.72$

Bethany did not do better than Richie because her average score was less than his.
