A right triangle has side lengths 7, 24, and 25 as shown below.

Hoochie [10]

Answer: Tan B = 0.2917 (16.26 degrees)

Sin B = 0.2800 (16.26 degrees)

Cos B = 0.9600 (16.26 degrees)

Step-by-step explanation: Please refer to the picture attached for details.

The right angled triangle LNB has been drawn with the sides labeled as 7, 24 and 25 as indicated. With angle B as the reference angle, we can now identify each side as follows;

Side 7 (opposite, facing the reference angle)

Side 24 (adjacent, between the reference angle and the right angle)

Side 25 (hypotenuse, facing the right angle).

Hence, using the trigonometric ratios,

Tan B = opposite/adjacent

Tan B = 7/24

Tan B = 0.2917 (16.26 degrees)

Sin B = opposite/hypotenuse

Sin B = 7/25

Sin B = 0.2800 (16.26 degrees)

Cos B = adjacent/hypotenuse

Cos B = 24/25

Cos B = 0.9600 (16.26 degrees)

Write an equation (a) in slope intercept form and (b) in standard form for the line passing through (-2,6) and perpendicular to

Rudik [331]

Answer:

a) y = 3x+12

b) y-6 = 3(x+2)

Step-by-step explanation:

The equation of a line in slope-intercept form is expressed as y = mx+c

m is the slope or gradient

c is the intercept

We need to calculate the value of slope and intercept.

We will get the slope from the equation of line x+3y = 7

Rewriting the equation

3y = 7-x

y = 7/3 -x/3

M = -1/3

Since the equation if the unknown line is perpendicular to this line then Mm = -1 where m is the slope of the unknown line

m = -1/M

m = -1/(-1/3)

m = 3

To get c, we will substite the point given (-2,6) and the slope into the equation y = mx+c

6 = 3(-2)+c

6 = -6+c

c = 12

Substituting m= 3 and c = 12 into the standard form of the equation we have;

y = 3x+12 (This gives the required equation in its slope intercept form)

b) The standard form of a line is expressed as y-y1 = m(x-x1) where (x1,y1) are the points and m is the slope. On substituting the point {-2,6) and slope of 3 into this equation we will have:

y - 6 = 3(x-(-2))

y-6 = 3(x+2)

This gives the equation of the line in its standard form

The weekly sales of Honolulu Red Oranges is given by q = 896 − 20p.(A) Calculate the price elasticity of demand when the price i

vitfil [10]

Answer with Step-by-step explanation:

Since we have given that

q = 896-20p

p = $32

.(A) Calculate the price elasticity of demand

As we know that

$e=-\dfrac{dq}{dp}\times \dfrac{p}{q}\\\\e=-(-20)\times \dfrac{32}{896-20p}\\\\e=\dfrac{20\times 32}{896-20p}\\\\e=\dfrac{640}{896-20p}\\\\e=\dfrac{640}{896-640}\\\\e=\dfrac{640}{256}=2.5$

(B) The demand is going down with increase in 15 increase in price at that price level, as we know that there is inverse relationship between price and quantity demanded.

(C) Also, calculate the price that gives a maximum weekly revenue.

$R=pq\\\\R=p(896-20p)\\\\R=896p-20p^2$
