Write an equation of the line that is perpendicular to the line y = 4x - 10 that passes through the point (-16, 2).
A)
y = - 3x - 2
y = -4x+6
y=-3x+2
y = 4x + 2

Answers

Answer 1

Answer:

y = -1/4x -2

Step-by-step explanation:

the perpendicular slope would be -1/4

2 = -1/4 (-16) + b

b = -2

the equation should be y = -1/4x -2

Step-by-step explanation:

A Bowling ball is rolled down the alley with the constant velocity of 1.6 m/sec at an angle of 85° to the starting line, the position of the person throwing a bowling ball can be represented by the point (0,0). where is the ball after six seconds?

Answers

We have been given that a Bowling ball is rolled down the alley with the constant velocity of 1.6 m/sec at an angle of 85° to the starting line, the position of the person throwing a bowling ball can be represented by the point (0,0).

We are asked to find the position of ball after 6 seconds.

We will use horizontal position and vertical position formula to solve our given problem.

Horizontal position is given by formula: [tex]x=v\cdot \text{cos}(\theta)\cdot t[/tex] and vertical position is given by formula: [tex]y=v\cdot \text{sin}(\theta)\cdot t[/tex],where,

v = Velocity,

t = Time,

[tex]\theta[/tex] = Angle to the starting line.

For our given problem [tex]v=1.6[/tex], [tex]t=6[/tex] and [tex]\theta=85^{\circ}[/tex].

[tex]x=1.8\cdot \text{cos}(85^{\circ})\cdot 6[/tex]

[tex]x=10.8 \cdot 0.087155742748[/tex]

[tex]x=0.9412820216784\approx 0.94[/tex]

[tex]y=1.8\cdot \text{sin}(85^{\circ})\cdot 6[/tex]

[tex]y=10.8\cdot 0.996194698092[/tex]

[tex]y=10.7589027\approx 10.76[/tex]

Therefore, the position of ball after 6 seconds would be [tex](0.94,10.76)[/tex].

Answer:

(0.8,9.6)

Step-by-step explanation:

x=1.6*cos85* 6=0.8

y=1.6*sin85 *6=9.6

George still has 40 percent of his book to read. If George has read 180 pages, how many pages does he still have to read? How do you know?

Answers

Answer:  72

Step-by-step explanation:    so you do a line = line method the lines should look like they are fractions.  

you do it for the both numbers the percent is always out of 100.

it should look like this

40%            ?

--------- = -----------    

100%       180

then you cross multiply 40 and 180 and than divide it by 100.   your answer should be 72.    you later replace the ? with 72

you know this because It is smaller than 180 and its bigger than the number 40.

The number pages left to read is 12 pages.

Given that, George still has 40 percent of his book to read.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Let the total number of pages be x.

Now, x-40% of x=180

⇒ x-0.4x=180

⇒ 0.6x=180

⇒ x=180/0.6

⇒ x=300

So, remaining pages = 300-180=120

Therefore, the number pages left to read is 12 pages.

Find the distance between the line segments XY & YZ

XY = 4 units

YZ = 5 units

Use the following equation to solve for the hypotenuse of the triangle:

Hypotenuse = √(a² + b²)

Let: a = XY

      b = YZ

Hypotenuse = √(4² + 5²)

Remember to follow PEMDAS. Solve the parenthesis first, and the powers first before adding:

Hypotenuse = √(16 + 25)

Hypotenuse = √(41)

B) 41 is your answer, if you keep it as c². However, if it is not, then none of your answer choices work, as the answer would be √41.

Given the equation, (x - h)2 + (y - k)2 =r2, what are the coordinates of the center?
The coordinates of the center are ( , )

Answers

Answer:

(h, k).

Step-by-step explanation:

This is the standard form of the equation of a circle

The coordinates of the center are (h, k)

The radius is r.

The coordinates of the center are (h, k).

What is Circle?

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Given that;

The equation is,

⇒ (x - h)² + (y - k)² = r²

Now, We know that;

The standard form of the equation of circle is,

⇒ (x - h)² + (y - k)² = r²

Where, (h, k) is coordinates of the center and r is the radius of the circle.

Hence, By comparing, we get;

The coordinates of the center are (h, k).

Find the number of square units in base and height for each triangle.

Answers

Answer:

a. base = 5 units; height = 4 units

b. base = 1 unit; height = 4 units

c. base = 1 unit; height = 4 units

Step-by-step explanation:

a. Count the bottom which is the base, which is 5, the height, or h would be the units or squares up which would be 4.

b. Count the only 1 on the bottom which then, base would be 1 because there is only one on the bottom, the rest is going diagonally so it doesn't count as the base. The height would be 4 because there are 4 units up.

c. Again, only 1 unit on the bottom so the base is one again, and 4 as the height again because of how much units high it is.

The only difference from b. to c. is that c. is having a different angle than b, but they are both the same!
