Answer:

x = 13.48

Step-by-step explanation:

Given that,

Angle, \theta=26^{\circ}

base, b = x

Hypotenuse, H = 15

We need to find the measure of x. It can be solved using trigonometry i.e.

\cos\theta=\dfrac{b}{H}

Put all the values,

\cos(26)=\dfrac{x}{15}\\\\x=15\times \cos(26)\\\\x=13.48

So, the value of x is equal to 13.48.

kiruha [24]

The discount amount would be $1470.00

the new cost of the car would be $19530.00

For given question,

A car dealer gave a 7% discount to the first 50 people through the door.

the car you are interested in cost $21,000.00

We need to find the discount amount and the new price of the car.

A car dealer gave a 7% discount.

this means, to find the discount amount, we need to find the 7 percent of $21,000.00

⇒ discount amount = 7 percent of $21,000.00

⇒ discount amount = (7 / 100) × 21,000.00

⇒ discount amount = $1470.00

So, the new price of the car would be,

the new price of the car = original price - discount amount

⇒ the new price of the car = $21,000.00 - $1470.00

⇒ the new price of the car = $19530.00

Therefore, the discount amount would be $1470.00

the new cost of the car would be $19530.00

Vanyuwa [196]
The answer is 1,670 because you have to multiply 35*8 which equals 280 and subtract it from 1950, and you get 1,670.

An object is launched at 19.6 m/s from a height of 58.8 m. The equation for the height (h) in terms of time (t) is given by h(t)
beks73 [17]
H(t) = Ho +Vot - gt^2/2

Vo = 19.6 m/s
Ho = 58.8 m
g = 9.8 m/s^2

H(t) = 58.8 + 19.6t -9.8t^2/2 = 58.8 + 19.6t - 4.9t^2

Maximun height is at the vertex of the parabole

To find the vertex, first find the roots.

58.8 + 19.6t - 4.9t^2 = 0

Divide by 4.9

12 + 4t - t^2 = 0

Change sign and reorder

t^2 - 4t -12 = 0 

Factor

(t - 6)(t + 2) =0 ==> t = 6 and t = -2.

The vertex is in the mid point between both roots

Find H(t) for: t = [6 - 2]/2 =4/2 = 2

 Find H(t) for t = 2

H(6) = 58.8 + 19.6(2) - 4.9(2)^2 = 78.4

Answer: the maximum height is 78.4 m
