Hi!

We can see the river is a straight line.

This means that the angles that fall upon it are supplementary angles, and will add up to 180 degrees.

Therefore:

[tex]x+2x+21=180[/tex]

Combine like terms:

[tex]3x+21=180[/tex]

Subtract 21 from both sides:

[tex]3x=159[/tex]

Divide both sides by 3:

[tex]x=53[/tex]

Therefore, the value of x is 53 degrees.

The exponential function is given as 3.68 × (2.52)ˣ. Then the value of function at x = 6 will be 942.43.

The exponent denotes that the base will rise to a specific level of strength. The base is X, and the power is n.

If f(x) is an exponential function where f(2) = 23 and f(3) = 58.

Then the exponential function will be

f(x) = abˣ

If f(2) = 23, then we have

23 = ab² ...1

If f(3) = 58, then we have

58 = ab³ ...2

Then from equations 1 and 2, we have

a = 3.62 and b = 2.52

Then the function will be

f(x) = 3.68 × (2.52)ˣ

Then the value of f(6) will be

f(6) = 3.68 × (2.52)⁶

f(6) = 3.68 × 256.1

f(6) = 942.43

Step-by-step explanation:

I assume that one a student is picked for an oral exam, the same student will not be picked again.

the total number of possibilities to pick 14 students out of 18 is C(18, 14) = 18!/(14! × (18-14)!) = 18!/(14! × 4!) =

= 18×17×16×15/(4×3×2) = 18×17×2×5 =

= 3,060

how many of these possibilities contain exactly 8 girls and 6 boys ?

so, we choose 8 out of the 10 girls, and 6 out of the 8 boys.

that means

C(10, 8) × C(8, 6) = 10!/(8! × 2) × 8!/(6! × 2) =

= 10×9/2 × 8×7/2 = 5×9 × 4×7 =

= 45 × 28 = 1,260

so, the probability to have 8 girls and 6 boys in a random selection of 14 students out of 18 is

1260/3060 = 21/51 = 7/17 = 0.411764706... ≈ 0.412

These are sequence that increases in an exponential manner. The value of the log function is 55

These are sequence that increases in an exponential manner. The nth term of the sequence is expressed as:

Tn = ar^n-1

Given the following

Substitute

Tn = x = 8(2)^52
x = 8(2)^52

Take the log of the result to have:

[tex]log_28(2)^{52} = log_22^{55}\\ log_22^{55} = 55log_22=55[/tex]

Hence the value of the log function is 55

now, notice, 0 is also a solution, which means at 0 seconds the ball was touching the ground, well, it was kicked "from" the ground, so at 0 seconds it was initially on the ground anyway.

Answer:

no solution

Step-by-step explanation:

Given equation:

3(2x + 4) - 8x = -2(x + 1) + 3

Expand the brackets:

⇒ 3(2x) + 3(4) - 8x = -2(x) - 2(1) + 3

⇒ 6x + 12 - 8x = -2x - 2 + 3

Collect like terms:

⇒ 6x - 8x + 12 = -2x - 2 + 3

Combine like terms:

⇒ -2x + 12 = -2x + 1

Subtract 12 from both sides:

⇒ -2x + 12 - 12 = -2x + 1 - 12

⇒ -2x  = -2x - 11

Add 2x to both sides:

⇒ -2x + 2x  = -2x +2x - 11

⇒ 0 = -11

The sides are not equal, therefore there is no solution

Decay

Step-by-step explanation:

Any "r" value between 0 and 1 indicates an exponential function in decay. The "r" value is the one in the parentheses and raised to the exponent. In this case, the value is 0.91. This number falls within the "r" value boundaries of a decaying exponential function.

If the polar coordinate of a point is (9, π/5). Then the cartesian coordiante will be (7.28, 5.29).

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

The polar coordimnate is given below.

P(9, π/5)

Then the cartesian coordinate will be

We know that the conversion of the polar coordinate to the cartesian coordinate.

(x, y) = (r cos θ, r sin θ)

Then we have

r = 9

θ = π/5

Then we have

x = 9 cos π/5

x = 7.28

y = 9 sin π/5

y = 5.29

Then the coordinate will be (7.28, 5.29).

The y-intercept is 6

Step-by-step explanation:

The y-intercept of a function is where the graph of an equation touches or crosses the vertical axis. This is usually the value of y when x = 0.

For this particular function, when x = 0 ⇒

f(0) = 0^2 + 4(0) + 6

= 0 + 0 + 6

= 6

Therefore, the y-intercept of this function is 6

Answer:

6

Step-by-step explanation:

the y-intercept is the last number of the equation

so because 6 is the last number, the y-intercept is 6

[tex]v = 905 \: {cm}^{3} [/tex]

the radius of the given ball (sphere).

[tex]r = \sqrt[3]{ \frac{3v}{4\pi} } [/tex]

[tex]r = \sqrt[3]{ \frac{3 \times 905}{4\pi} } [/tex]

[tex]r = 6 \: cm[/tex]

therefore, the radius of the ball is 6 cm.

note: refer to the picture I added on how you can change r as the subject of the formula.

[tex]r = (3 \frac{v}{4\pi} {)}^{ \frac{1}{3} } [/tex]

[tex]r = (3 \times \frac{905}{4 \times \pi} {)}^{ ^{ \frac{1}{3} } } [/tex]

[tex]r = 6.00049 \: cm[/tex]

[tex]r = 6 \: cm[/tex]

Hence, the radius of the beach ball is 6 centimeters.

The linear equation is y = (2/3)*x - 5, and the 4 points in the graph are:

{ (-1, -17/3),  (0, -5), (1, -13/3),  (2, -11/3)}

A linear equation written in the slope-intercept form is:

y = a*x + b

Where a is the slope and b is the y-intercept.

In this case, we have:

a = 2/3

b = -5

So our line is:

y = (2/3)*x - 5

To find the points, we need to evaluate the line in 4 different values of x.

We will use: x = -1, 0, 1, 2.

for x = -1 we have:

y = (2/3)*-1 - 5 = -2/3 - 5 = -17/3

So this gives the point (-1, -17/3).

for x = 0 we have:

y = (2/3)*0 - 5 = -5

So this gives the point (0, -5).

for x = 1 we have:

y = (2/3)*1 - 5  = -13/3

So this gives the point (1, -13/3).

for x = 2 we have:

y = (2/3)*2 - 5 = 4/3 - 15/3 = -11/3

So this gives the point (2, -11/3).

Then the 4 points are:

{ (-1, -17/3),  (0, -5), (1, -13/3),  (2, -11/3)}
