The equation is: 3x^3 = 4x + 8

The form is ax^2 + bx + c = 0

Rewrite the given equation to equal 0:

Subtract 3x^2 from both sides to get:-3x^2 + 4x + 8 = 0

Now give each letter their value:

a = -3, b = 4, c = 8

The slope of the line passing through the points (7, 5) and (21, 15) is ???

Volgvan

Answer:

(21,5)

Step-by-step explanation:

To find the slope that passes through the points (7,5) and (21,15) , we use the formula

m = (y2-y1)/ (x2-x1)

= (15-5)/(21-7)

= 10/14

=5/7

We want a slope that is 1/3 this slope so we will multiply by 1/3

5/7 * 1/3= 5/21

We know the slope and one point (0,0) we can use the same formula to figure out x and y

m = (y2-y1)/ (x2-x1)

5/21 = (y2-0)/ (x2-0)

Let the tops be equal and the bottoms be equal

5 = y2-0

5 =y2

and the bottoms

21 = x2-0

21= x2

We have the point

(21,5)

In order to select new board members, the French club held an election. 25% of the 84 members of the club voted. How many member

Sloan [31]

Answer: 21 people voted

Step-by-step explanation:

an easy way to do this is simply multiply 84 * 0.25.

This gives you $\frac{1}{4}$ of the original amount

in this case 84×0.25 = 21

This means that 21 people voted

A park is showing a movie on the lawn. The base of the screen is 6 feet off the ground and the screen is 22 feet high (see figur

inessss [21]

Answer:

A. 61.82°;

15.64°

B. 33.37°

Step-by-step explanation:

✍️Angle of elevation from 15 ft:

A right triangle is formed. Apply trigonometric ratios formula to find the angle of elevation from 15 ft.

Thus,

Length of the side Opposite to reference angle = 22 + 6 = 28 ft

Adjacent length = 15 ft

Thus, we would have:

$tan(\theta) = \frac{opp}{adjacent} = \frac{28}{15}$

$tan(\theta) = 1.8667$

$\theta = tan^{-1}(1.8667)$

$\theta = 61.82$ (2 d.p)

✍️Angle of elevation from 100 ft:

Thus,

Length of the side Opposite to reference angle = 22 + 6 = 28 ft

Adjacent length = 100 ft

Thus, we would have:

$tan(\theta) = \frac{opp}{adjacent} = \frac{28}{100}$

$tan(\theta) = 0.28$

$\theta = tan^{-1}(0.28)$

$\theta = 15.64$ (2 d.p)

✍️Distance you'd be from the screen if you lie on the ground and make an angle of elevation of 40° to the top of the screen:

Adjacent length = your distance from the screen = x

Opposite length = 22 + 6 = 28 ft

Angle of elevation = 40°

Tge trigonometric ratios formula to use would be:

$tan(\theta) = \frac{opp}{adjacent}$

Plug in the values

$tan(40) = \frac{28}{x}$

Multiply both sides by x

$x*tan(40) = 28$

Divide both sides by tan(40)

$x = \frac{28}{tan(40)}$

$x = 33.37$ (2 d.p)
