Answer:

B) 378 students could be expected to attend the game.

Step-by-step explanation:

Out of 40 students, 45% agreed,

45% of 40

= 45/100 * 40

= 18 students,

18 students out of 40 agreed.

So, Out of 840 students 18/40 * 840 students would be expected to agree. We get :- 378

there are different ways of solving this:

one way is the follwing:

cos^2(x) -sin^2(x) =cos (2x)

then, equation becomes:

cos (2x) -sin (x)=0

but sin(x) is also equivalent to : cos ((pi/2)-x),

so, the equation now is:

cos (2x) - cos ((pi/2)-x)=0 -------> cos (2x) = cos ((pi/2)-x) ---------> 2x=(pi/2) -x

but since it is an angle, the answer would be repeating so:

2x= 2k(pi) +((pi/2)-x)

3x= pi( 2k+1/2)

x= (pi/3) (2k+1/2)

for k=0, x= pi/6

for k=1, x= 5pi/6

for k=2, x= 3pi/2

Answer:

2

Step-by-step explanation:

(10 - 0)/(6 - 1) = 2

Answer:

All of them have intersections with each other, so we can't really say anything from that. But only -3x + 10 has a y-intercept higher than y=0.

So let's just say -3x+10 is different.

Answer:

2/5

Step-by-step explanation:

1/5 / 1/2= 1/5 x 2/1

2/5

Answer:

2/5

Step-by-step explanation:

The original answer was 4/10, but as a reduced fraction, it is 2/5.

Version of how I got it:

5 and 2 have 10 in common, so that is the denominator

1 and 1 have 1 in common. Keep change and flip, to turn this into a 4. this rule applies because 1 + 1 = 2, and 2 x 2 = 4.

finally...

4/10 -- 2/5

Find where the two curves intersect:

[tex]4x = x - x^2 + x^3[/tex]

[tex]\implies x^3 - x^2 - 3x = 0[/tex]

[tex]\implies x (x^2 - x - 3) = 0[/tex]

[tex]\implies x = 0 \text{ or } x^2 - x - 3 = 0[/tex]

Completing the square gives

[tex]x^2 - x - 3 = \left(x - \dfrac12\right)^2 - \dfrac{13}4 = 0[/tex]

and solving for x,

[tex]\implies x = \dfrac12 \pm \sqrt{\dfrac{13}4} = \dfrac{1 \pm \sqrt{13}}2[/tex]

The total unsigned area between the two curves is then

[tex]\displaystyle \int_{(1-\sqrt{13})/2}^{(1+\sqrt{13})/2} \left|4x - \left(x - x^2 + x^3\right)\right| \, dx[/tex]

[tex]= \displaystyle -\int_{(1-\sqrt{13})/2}^0 \left(4x - \left(x - x^2 + x^3\right)\right) \, dx + \int_0^{(1+\sqrt{13})/2} \left(4x - \left(x - x^2 + x^3\right)\right) \, dx[/tex]

[tex]= \displaystyle -\int_{(1-\sqrt{13})/2}^0 \left(3x + x^2 - x^3\right) \, dx + \int_0^{(1+\sqrt{13})/2} \left(3x + x^2 - x^3\right) \, dx[/tex]

where we use the definition of the absolute value function to split up the integral at the point where one curve "overtakes" the other - in other words, y = 4x lies above the curve y = x - x² + x³ when x > 0, and vice versa otherwise.

We have the antiderivative

[tex]\displaystyle \int (3x + x^2 - x^3) \, dx = \dfrac{3x^2}2 - \dfrac{x^3}x - \dfrac{x^4}4 + C[/tex]

so that by the fundamental theorem of calculus, the area we want is

[tex]\displaystyle \int_{(1-\sqrt{13})/2}^{(1+\sqrt{13})/2} \left|4x - \left(x - x^2 + x^3\right)\right| \, dx = \boxed{\dfrac{73}{12}}[/tex]

The areas bounded by the curve y₁ = 4x and y₂ = x − x² + x³ between the limit (−1.303, 2.303) is 6.083 square units.

When the two curves intersect then they bound the region is known as the area bounded by the curve.

The regions bounded by the graphs y₁ = 4x and y₂ = x − x² + x³ are shaded in the figure above.

The intersection point will be

4x = x − x² + x³

x³ − x² − 3x = 0

x = −1.303, 0, 2.303

Then the area bounded by the curve will be

[tex]\rm Area = \int _{-1.303}^{2.303} ( y_1 - y_2 ) dx\\\\\\Area = \int _{-1.303}^{2.303} 4x - (x-x^2+x^3) dx\\\\\\Area = \int _{-1.303}^{2.303} 4x - x+x^2-x^3) dx\\\\\\Area = \int _{-1.303}^{2.303} (3x + x^2-x^3) dx\\\\\\Area = \begin{bmatrix} \dfrac{3}{2}x^2 + \dfrac{1}{3}x^3 - \dfrac{1}{4} x^4 \end{bmatrix} _{-1.303}^{2.303}\\\\\\Area = \dfrac{73}{12}\\\\\\Area = 6.0833[/tex]

Answer:

x = 10 cm

Step-by-step explanation:

The volume of a pyramid is [tex]V = \frac{Bh}{3}[/tex], where V = volume, B = area of base, and h = height.

Step 1: Multiply both sides by 3.

Step 2: Divide both sides by 84.

Step 3: Check if solution is correct.

Therefore, x = 10 cm.

Reflect Over X-Axis Formula

The following formula is used to reflect a coordinate point about the x-axis.

(X2,Y2) = (X1,Y1) * (1,-1)

Where X2 and Y2 are the new reflected coordinates

X1 and Y1 are the original coordinate points

Reflect Over X-Axis Definition

Reflection over the x-axis is the process of producing a coordinate point that is mirrored across the x-axis of the coordinate plane. That is it has the same X coordinate and opposite y4 coordinate.

Reflect over X-Axis Example

How to reflect over the x-axis?

First, determine the original coordinate points.

For this example, we will say the coordinate points are (4,5).

Next, calculate the new coordinate points.

Using the formula above we calculate the new reflected points as (4,5)*(1,-1) = (4,-5).
