The graph shows the function f(x)=3^x
What is the value of x when f(x)=9?
A:3
B:1
C:0
D:2​

Answer:

x = [tex]11\sqrt{2}[/tex]

y = [tex]11\sqrt{2}[/tex]

Step-by-step explanation:

the ratio of the sides of a 45 - 45 - 90 triangle is shown at the bottom of this answer.

as you can see, it is x:x:[tex]x\sqrt{2}[/tex]

The side given is x[tex]\sqrt{2}[/tex], so you have:

[tex]x\sqrt{2}=22[/tex]

divide both sides by [tex]\sqrt{2}[/tex]

x = [tex]22/\sqrt{2}[/tex]

multiply this by [tex]\sqrt{2} /\sqrt{2}[/tex]

[tex]x = 22\sqrt{2}/2[/tex]

[tex]x=11\sqrt{2}[/tex]

y is also equal so y = [tex]11\sqrt{2}[/tex]

Answer:

48048

Step-by-step explanation:

Total number of players = 16

Selection to be made :

1 goalie ; 10 players

Hence ;

Choosing 1 goalie from 16 players :

16C1

Choosing 10 players from the remaining (16 - 1), 15 players

15C10

Hence,

16C1 * 15C10

16 * 3003

= 48048

Answer:

Step-by-step explanation:

Remark

I'm going to assume that the edges of the cubes are 1/2 inch on each side.

V = 1/2 * 1/2 * 1/2 = 1/8 cubic inches.

Volume of the box

V = L * w * h

Givens

L = 2 inches

w = 3.5 inches

h = 5.5 inches

Solution

V = L * w * h

V = 2 * 3.5 * 5.5

V = 38.5

1/8 has the decimal equivalent value of 0.125

Number of cubes needed = Volume of the box / volume of the cube

Number of cubes needed = 38.5 / 0.125

Number of cubes needed = 308

The answer is A. 4, [tex]\sqrt{8}[/tex], 24

H is correct

Step-by-step explanation:

Answer: m∠5 = 75°.

Step-by-step explanation:

We know that lines A and B are parallel, and angles 1 and 5 are formed by the same line intersecting the parallel lines.

We know that:

"When a line intersects two parallel lines, corresponding angles are formed, such that we could think on four quadrants, the angles in each quadrant are equivalent between them"

Well, here we can see that angle ∠1 and angle ∠5 are formed by the same line, and both are in the same quadrant (would be the third quadrant if we use standard notation)

Then the measure of ∠1 is the same as the measure of ∠5

And we know that m∠1 = 75°

Then we must have that m∠5 = 75°.

Answer:

80%

Step-by-step explanation:

If you do 4 divided by 5 it equals 0.8, which is 80%

Answer:

The answer is 80%

Step-by-step explanation:

Answer: Percent" or "%" means "out of 100" or "per 100", Therefore 7% can be written as 7100 . Because 7 is a prime number and cannot be factored this is the simplest form.

Answer:

B. -5

Step-by-step explanation:

this is quite simple, so what you are going to want to do is multiply -3 by 4, and -16, so distribute that and you'll end up with

-12x+48= -12

then you want to subtract 48 from both side to leave the x on one side alone

that will be -12x= -60

after that you have to divide both sides by -12 to find your x

so then you will see that your x is = -5! hope this helps!!

Step-by-step explanation:

not entirely sure but i hope this helps :) have a nice day !!

The values of x and y in the following equation system are 20 and 110, respectively.

simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.

given a system of equation:

30x + 4y = 1,040.....(1)

12x + 16y = 2,000...…(2)

We will solve it by using substitution method,

Multiply with 2.5 in equation (2) and subtract it from equation (1)

30x + 4y - 30x - 40y = 1040 - 5000

36y = 3960

y = 110

Substitute this value of y in equation (1)

30x + 440 = 1040

30x = 600

x = 20

Therefore, The value of x and y are 20 and 110 respectively for the given system of equation.

Answer:

3 = ?

Step-by-step explanation:

The triangles are similar, so we  can use ratios

15           12 -2

------   = --------------

15+?          12

15           10

------   = --------------

15+?          12

Using cross products

15 * 12 = 10 ( 15+?)

180 = 10 ( 15+?)

Divide each side by 10

18 = 15+?

Subtract 15 from each side

18-15 = 15+?-15

3 = ?
