Answer 1

Answer: F=72

g=6

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

$\cos { \left( F \right) } =\frac { { e }^( 2 )+{ g }^( 2 )-{ f }^( 2 ) }{ 2eg }$

Therefore:

$\cos { \left( 72 \right) } =\frac { { e }^( 2 )+{ 6 }^( 2 )-{ f }^( 2 ) }{ 2\cdot e\cdot 6 } \n \n \cos { \left( 72 \right) } =\frac { { e }^( 2 )+36-{ f }^( 2 ) }{ 12e }$

$\n \n 12e\cdot \cos { \left( 72 \right) } ={ e }^( 2 )+36-{ f }^( 2 )\n \n \therefore \quad { f }^( 2 )={ e }^( 2 )-12e\cdot \cos { \left( 72 \right) } +36\n \n \therefore \quad f=\sqrt { { e }^( 2 )-12e\cdot \cos { \left( 72 \right) +36 } } \n \n \therefore \quad f=\sqrt { e\left( e-12\cos { \left( 72 \right) } \right) +36 }$

But what is e?

E=76

G=32

g=6

And:

$\frac { e }{ \sin { \left( E \right) } } =\frac { g }{ \sin { \left( G \right) } }$

Which means that:

$\frac { e }{ \sin { \left( 76 \right) } } =\frac { 6 }{ \sin { \left( 32 \right) } } \n \n \therefore \quad e=\frac { 6\cdot \sin { \left( 76 \right) } }{ \sin { \left( 32 \right) } }$

If you take this value into account, you will discover that f is...

$f=\sqrt { \frac { 6\cdot \sin { \left( 76 \right) } }{ \sin { \left( 32 \right) } } \left( \frac { 6\cdot \sin { \left( 76 \right) } }{ \sin { \left( 32 \right) } } -12\cos { \left( 72 \right) } \right) +36 } \n \n \therefore \quad f=10.8\quad \left( 1\quad d.p \right)$

So I would have to say that the answer is approximately (c).

A lab is growing bacteria in a culture dish. The amount of bacteria in the dish doubles every 3 hours. Initially, there are 500 bacteria in the dish. How many are in the dish after 9 hours A. 4,500 B. 4,000 C. 1,500 D. 13,500

Answers

Answer: B. 4,000

Step-by-step explanation:

Given: The initial amount of bacteria in the dish A= 500

Since, The amount of bacteria in the dish doubles every 3 hours.

The multiplicative rate of change after every 3 hours = 2

Time period = 3 hours

By exponential function, we have the amount of bacteria after time period 'x' is given by :-

$y=Ab^x$ , where A is the initial amount , b is the multiplicative rate of change in time period x.

Number of 3 hours period in 9 hours = 3

Therefore, x=3

Therefore, the amount of bacteria in the dish after 9 hours is given by :_

$y=500(2)^3=500*8=4000$

d- 500*3
*3
*3 = 13500

(7^x)^4= 7^2*7^3/7^x3

Answers

hope this helps you note only if it is the correct question then the answer will be correct

Answer:

(7^x)^4 = (7^2 * 7^3)/7^3x

7^4x = 7^5/7^3x

7^4x = 7^5-3x

4x = 5 - 3x

7x = 5

x = 5/7

Find the area of a 45°-45°-90° triangle with a hypotenuse of 24. a. 144 square units c. 99 square units b. 125 square units d. 100 square units

Answers

area=1/2 times base times height

remember that 45-45-90 triangle has sides of x,x and x√2
(legs are measure x and hypotonuse=x√2)

the legs are equal and are also the base and height
find the legs (x=leg)

hypotonuse=24
24=x√2
divide both sides by √2
24/(√2)=leg=base=height

volume=1/2 times base times heigth
V=1/2 times (24/√2) times (24/√2)
V=1/2 times (576/2)
V=576/4
V=144 units^2

answer is A

Given the graph below, find GH.-
Is this asking to find the coordinates, or to find the distance?

Answers

Answer:

$GH = 6.3$ (nearest tenth)

Step-by-step explanation:

Given:

G(-2, -3)

H(0, 3)

Required:

Distance between point G and H = GH

Solution:

Distance between G(-2, -3) and H(0, 3):

$GH = √((x_2 - x_1)^2 + (y_2 - y_1)^2)$

Let,

$G(-2, -3) = (x_1, y_1)$

$H(0, 3) = (x_2, y_2)$

$GH = √((0 - (-2))^2 + (3 - (-3))^2)$

$GH = √((2)^2 + (6)^2)$

$GH = √(4 + 36) = √(40)$

$GH = 6.3$ (nearest tenth)

Answers

Answer:

200 m³

Step-by-step explanation:

The volume of cylinder = π · r² · h

We Know

Area of circle = 25 m²

h = 8 m

We take

25 x 8 = 200 m³

So, the volume of the cylinder is 200 m³.
