Answer:

A. $-2\sqrt{2\pi }$

Step-by-step explanation:

$f(x)=sin(x^{2}+\pi )$

$f^{'}(x)=cos(x^{2} +\pi ) 2x$

$f^{'}(\sqrt{2\pi } )=cos(2\pi +\pi )2\sqrt{2\pi }$

$f^{'} (\sqrt{2\pi } )=-1 (2\sqrt{2\pi } )$

Find the following, giving your answers to 1 decimal place?

sweet [91]

Answer:

I. Volume = 301.6 cm³ (to 1d.p)

II. CSA = 188.5 cm² (to 1d.p)

Step-by-step explanation:

Given the following data;

Height, h = 8cm

Radius, r = 6cm

Curved length = 10cm

a. To find the volume of the cone

$V = \frac{1}{3} \pi r^{2}h$

Where;

V is the volume of the cone.

r is the radius of the base of the cone.

h is the height of the cone.

Substituting into the equation, we have;

$Volume = \frac{1}{3} * 3.142*6^{2}*8$

$Volume = \frac{1}{3} * 3.142*36*8$

$Volume = 3.142*12*8$

Volume = 301.6 cm³ (to 1d.p)

b. The curved surface area of the cone

$CSA = \pi rl$

Where;

CSA is the curved surface area of the cone.

r is the radius of the base of the cone.

l is the curved length of the cone.

Substituting into the equation, we have;

$CSA = 3.142*6*10$

CSA = 188.5 cm² (to 1d.p)

Solve the equation for y in terms of x 12x + 3y = 12

defon

Answer:

y = 4 - 4x

Step-by-step explanation:

Step 1: Write equation

12x + 3y = 12

Step 2: Subtract 12x on both sides

3y = 12 - 12x

Step 3: Divide both sides by 3

y = 4 - 4x

The probability that a student at your school takes Drivers Education and Spanish is 87/1000. The probability that a student tak

Gnom [1K]

Let
x---------> The probability that a student takes Spanish
y-------> the probability that a student takes Drivers Education given that the Student is taking Spanish
z-------> The probability that a student at school takes Drivers Education and Spanish

we know that
z=x*y------> solve for y
y=z/x
z=87/1000
x=68/100
substitute
y=(87/1000)/(68/100)-----------> y=87/680

the answer is
87/680
