Answer:

BRO HE IS THE BEST SO I SUBBED

Given :

Solve [0, 2π)

3cos(2x) = 5sin(x) - 1

To Find :

The value of x in range [0,2π).

Solution :

We know, cos(2x) = 1 - sin²x .

3( 1 - 2sin²x ) = 5sinx - 1

3 - 6sin²x = 5sinx - 1

6sin²x + 5sinx - 4 = 0

6sin²x + 8sinx - 3sinx - 4 = 0

2sinx( 3sinx + 4 ) - 1( 3sinx + 4) = 0

sin x = 1/2  and sin x = -4/3 .

Since, sin x ≤ 1.

So, sin x = 1/2 .

x = π/6 .

Therefore, value of x is π/6.

Hence, this is the required solution.

Answer:

the indicated angle should be 121°

Step-by-step explanation:

If 2 lines are parallel to each other & a transversal intersects both of them , the corresponding angles on a same side are equal.

If the indicated angle will be equal to the given angle , they will be known as corresponding angles only when v || u.

So the indicated angle is 121°

Answer:

y = 15x^3 + 16x^2 - 55x + 24

Step-by-step explanation:

y = (3x +8)(5x - 3)(x - 1)

y = (15x^2 - 9x + 40x -24) * (x - 1)

y = (15x^2 + 31x - 24) * (x-1)

y = 15x^3 - 15x^2 + 31x^2 - 31x - 24x + 24

The x-intercepts of a graph are the points where the graph crosses the x-axis.

The x-intercepts are: [tex]\mathbf{x = ,-\frac83, \frac 35\ and\ 1}[/tex]

The function is given as:

[tex]\mathbf{y = (3x + 8)(5x - 3)(x - 1)}[/tex]

First, we plot the graph of [tex]\mathbf{y = (3x + 8)(5x - 3)(x - 1)}[/tex]

See attachment for the graph

Next, write out the x-values when the graph crosses the x-axis.

From the graph, we have:

[tex]\mathbf{x = -\frac 83}[/tex]

[tex]\mathbf{x = \frac 35}[/tex]

[tex]\mathbf{x = 1}[/tex]

Hence, the x-intercepts are: [tex]\mathbf{x = ,-\frac83, \frac 35\ and\ 1}[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

Given that Andre rode his bike at a constant speed.

Number of miles driven = 1 mile

Time taken to drive 1 mile = 5 minutes.

Then speed can be calculated using formula:

Speed = Distance / Time

Now we have to find the amount of time t (in minutes) taken by him to right distance d so we can again use same formula.

Speed = Distance / Time

or

Time = Distance / Speed

Plug the given values

t = 5d

Hence find answer will be equation t=5d.

Answer: 2x - y = 1 this should be it

The equation in standard form, y = 2x -1

The equation of line is an algebraic form of representing the set of points, which together form a line in a coordinate system.

Given an equation, y = 2x-1

The standard form is given as - y = mx+c

The given equation is already in standard form, where, m = 2, c = -1

Hence, The equation in standard form, y = 2x -1

Step-by-step explanation:

D. h(t) = -16(t - 5)² + 403 could be used to model this situation.

A baseball is hit from an initial height of 3 feet.

The baseball reaches a maximum height of 403 feet.

Here, h(t) indicates the height in feet after t seconds.

At the start, t = 0 & Initial height = 3 feet ,i.e. h(0) = 3

We have to verify options by putting t = 0

A.  h(t) = -16(t - 403)² + 3

So, h(0) = -16(0-403)² + 3 = -16(-403)² +3 = -2598544+3 = -2598541

B.  h(t) = -16(t - 5)² + 3

So, h(0) = -16(0-5)² + 3 = -16(-5)² + 3 = -400+3 = -397

C.  h(t) = -16(t - 3)² + 403

So, h(0) = -16(0-3)² + 403 = -16(-3)² + 403 = -144 + 403 = -259

D.  h(t) = -16(t - 5)² + 403

So, h(0) = -16(0-5)² + 403 = -16(-5)² + 403 = -400 + 403 = 3

Hence, in this function h(0) = 3 verified.

Therefore h(t) = -16(t - 5)² + 403 is the required function.
