Find the value of θ,
θ = arccos -8/9 = 152.734 deg
You can substitute this value for the requirement.
tan 152.734 = -0.51539
sin 152.734 = 0.45812

A hiker walking at a constant rate of 4 miles per hour is passed by a cyclist traveling in the same direction along the same pat

erastovalidia [21]

Answer: the cyclist must wait for 25 minutes until the hiker catches up.

Step-by-step explanation:

Distance = speed × time

The Cyclist was travelling in the same direction along the same path

as the hiker at a constant rate of 20 miles per hour. If the cyclist stops to wait for the hiker 5 minutes after passing her, then the distance that the cyclist travelled in 5 minutes(5/60 hour) is

20 × 5/60 = 100/60 miles

For the hiker to catch up with the cyclist, she would cover 100/60 miles at a speed of 4 miles per hour.

Time = distance/speed

Time required by hiker to catch up with the cyclist is

(100/60)/4 = 100/240 hour

Converting 100/240 hour to minutes, it becomes

100/240 × 60 = 25 minutes

Please solve for M<QTR

Andru [333]

Answer:

m∠QTR = 98°

Step-by-step explanation:

From the picture attached,

Radii of the circle are TQ and TR measuring equal lengths.

Therefore, ΔTQR is a isosceles triangle.

Opposite angles of the equal sides will be equal in measure.

m∠RQT = m∠TRQ = 41°

By angle sum theorem,

m∠RQT + m∠TRQ + m∠QTR = 180°

41° + 41° + m∠QTR = 180°

m∠QTR = 180° - 82°

= 98°

Therefore, m∠QTR = 98°

Solve by using the square root method.

ehidna [41]

4x^2-8=136 subtract 136 from both sides

4x^2-144...this is a difference of perfect squares so

(2x+12)(2x-12)

x=±6 or as they put it:

{-6, 6}

A line is perpendicular to

kap26 [50]

Note: your answer options suggest as if your actual question was

y = -4x - 9 instead of y = -x-9

But, anyways I am solving with respect to both equations

Answer:

Please check the explanation.

Step-by-step explanation:

IN CASE YOUR EQUATION ⇒ y = -x - 9

The slope-intercept form of the line equation

y = mx+b

where m is the slope and b is the y-intercept

Given the line

$y = -x-9$

comparing with the slope-intercept form (y = mx+b) of the line

Therefore, slope of the line = m = -1

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -1

perpendicular slope = – 1/m = -1/-1 = 1

Thus the slope of this perpendicular line will be: 1

IN CASE YOUR EQUATION ⇒ y = -4x - 9

Given the line

$y = -4x - 9$

comparing with the slope-intercept form (y = mx+b) of the line

Therefore, slope of the line = m = -4

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -4

perpendicular slope = – 1/4 = -1/-4 = 4

Thus the slope of this perpendicular line will be: 4
