Answer:

Step-by-step explanation:

first multiply 1 with 2+5i then multiply 2i with 2+5i and you will get

2+5i+4i+10i^2

then in the next step add 4i and 5i you will get 9i

in the next step put i^2=-1 and you will get -10

in the last step just substract 2-10 you will get -8 and 9i

and your answer will be -8+9i

8. If a runner’s power is 400 W as she runs, how much chemical energy does she convert into other forms in 10.0 minutes? E = P X

spin [16.1K]

Answer:

2400kJ

Step-by-step explanation:

Step one:

given data

power P= 400W

time = 10minutes

to seconds= 60*10 = 600 seconds

Required

the energy

Step two:

we know that Energy= power * time

E=P*t

E=400*600

E=240000

E=2400kJ

She converts 2400kJ into other forms

A cone has a height of 8 yards and a radius of 3 yards. What is its volume?

V125BC [204]

<h3>Given:</h3>

h= 8 yd
r= 3 yd

h= Height
r= Radius

The volume of the given cone.

<h3>Solution:</h3>

$\large\boxed{Formula:V= \frac{1}{3}\pi{r}^{2}h}$

$\large\boxed{\red \pi \red = \red 3 \red . \red 1 \red 4}$

Let's solve!

Substitute the values according to the formula.

$V= \frac{1}{3}×3.14×{3}^{2}×8$

$\large\boxed{V= 75.36 \: {yd}^{3}}$

Therefore, the volume of the given cone is 75.36 cubic yards.

Enter the number that belongs in the green box.

ale4655 [162]

Answer:

the green box is 0

Step-by-step explanation:

we are asked to find the x-intercept, which means y = 0

(x, y)

Another way to test this is plug it in 1 for x! (1, y) where x = 1

$y = \frac{2x^{2} -3x+1}{2x^{2} +8x+6} \\\\$

$y = \frac{2(1)^{2} -3(1)+1}{2(1)^{2} +8(1)+6}$

$y = \frac{2(1) -3(1)+1}{2(1) +8+6}$

$y = \frac{2 - 3 + 1}{2 + 8 + 6}$

$y = \frac{-1+1}{10 + 6}$

$y = \frac{0}{16}$

y = 0
