It might be rotation or refection depending on how the rotation is, fancy r might be radius depending though not sure what the r looks like<span />

Solve for the distance between (13,55) and (61,22). Round your answer to the nearest hundredth.

Neporo4naja [7]

Answer:

Step-by-step explanation:

position 1: (13,55)

position 2: (61,22)

distance = $\sqrt{(p_{x2}-p_{x1})^{2} + (p_{y2}-p_{y1} )^{2}}$

distance = $\sqrt{(61-13)^{2} + (22-55)^{2}}$

distance = $\sqrt{(48^{2} + (-33)^{2} }$

distance = $\sqrt{2304 + 1089}$

distance = $\sqrt{3393}$

distance = 58.25

The line with equation a + 4b = 0 coincides with the terminal side of an angle θ in standard position and cos θ > 0. What is

ankoles [38]

Answer:

Option A. -( $\frac{\sqrt{17}}{17}$ )

Step-by-step explanation:

Equation of a given line is a + 4b = 0 or b = - $\frac{1}{4}a$

This in the form of y = mx + b, which is slope-intercept form.

Here slope of the line is ( $-\frac{1}{4}$ ).

Or tanθ = $\frac{(-1)}{4}$

This line coincides with the terminal side of the angle in standard position where cosθ > 0

Since tanθ = $\frac{\text{Height}}{\text{Base}}$

and sinθ = $\frac{\text{height}}{\txt{Hypotenuse}}$

Hypotenuse = $\sqrt{\text{height}^{2}+\text{Base}^{2}}$

= $\sqrt{(1^{2}+4^{2})}$

= $\sqrt{17}$

Since tanθ is negative and cosθ > 0 that means θ lie in fourth quadrant.

Therefore, sinθ will be negative.

[ $\frac{-sin\theta}{+cos\theta}=-tan\theta$ ]

sinθ = - $\frac{1}{\sqrt{17}}$

= - $\frac{1}{\sqrt{17}}\times \frac{\sqrt{17} }{\sqrt{17}} = -\frac{\sqrt{17}}{17}$

Answer will be option A.

. A business-woman sold a gas cooker for $1209.60 making a profit of 12% on the cost price. Calculate the cost price of the gas

KiRa [710]

Answer:

$1080

Data given:

selling price (SP): $1209.60

percentage profit: 12%

To calculate out percentage profit

profit% = gain/cost price × 100

gain = selling price - cost price

hence we have:

(1209.60 - cost price)/cost price ×100 = 12

when we cross multiply

we have 12costprice = (1209.60×100)-(100×cost price)

12CP=120960-100CP

collect like terms

12CP+100CP = 120960

112CP=120960

divide both sides by the coefficient of CP

CP = $1080
