Line segment ON is perpendicular to line segment ML.
sergeinik [125]

Answer:

The length of NP is 2 units.

Step-by-step explanation:

Given the radius of 5 units and the length of MP is 4 units in the circle

we have to find the length of NP    

OL=OM=5 units  ( ∵ Radii of same circle)

In ΔOMP, by Pythagoras theorem

OM^2=MP^2+OP^2

5^2=4^2+OP^2

OP^2=25-16=9

OP=3 units

As we see

ON=OP+NP

5=3+NP

NP=5-3=2\thinspace units

Hence, the length of NP is 2 units.

Option D is correct.

Relationship A has a lesser rate than Relationship B. This table represents Relationship B.
Alja [10]

Answer:

y = 18.1x ; and y = 18x

Explanation:

The rate of change in Relationship B can be found by using the formula for slope:

m=\frac{y_2-y_1}{x_2-x_1}

Using the first two points, we have

m=\frac{73-36.50}{4-2}=\frac{36.50}{2}=18.25

We know that Relationship A has a lesser rate than this.  The choices given for Relationship A are written in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept (in this case b = 0).

The slope of the first equation is 18.1; this is less than 18.25.

The slope of the second equation is 18.6; this is greater than 18.25.

The slope of the third equation is 18.3; this is greater than 18.25.

The slope of the fourth equation is 18; this is less than 18.25.

Solve for x I need help on this question
AlexFokin [52]

Answer:

x\approx7.8

Step-by-step explanation:

In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:

sin(\theta)=\frac{opposite}{hypotenuse}

sin(23^\circ)=\frac{x}{20}

20sin(23^\circ)=x

x=20sin(23^\circ)

x\approx7.8

Therefore, the length of the opposite side is about 7.8 units

Jason can travel 24 3/4 miles in one half hour what is his average speed in miles per hour
BARSIC [14]
Average speed = 24 3/4 / 1 1/2 = 99/4 / 3/2 = 99/4 x 2/3 = 16 1/2 miles per hour.
