5/8 + 3/4 divided by -2/3 - 5/6

Answer:

[tex]C = (1,0)[/tex]

[tex]E = (0.8,0)[/tex]

See attachment for C and E

Step-by-step explanation:

Given

[tex]O= (0,0)[/tex] --- Origin

[tex]CO = 1[/tex] --- distance of C to O

Solving (a): Plot point C

Calculate the coordinates of C using distance formula:

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 -y_1)^2}[/tex]

Where:

[tex]O= (0,0)[/tex] ---[tex](x_1,y_1)[/tex]

[tex]C = (x,y)[/tex] -- [tex](x_2,y_2)[/tex]

[tex]d = CO = 1[/tex]

So, we have:

[tex]1 = \sqrt{(x - 0)^2 + (y -0)^2}[/tex]

[tex]1 = \sqrt{x^2 + y^2}[/tex]

Square both sides

[tex]1^2 = x^2 + y^2[/tex]

[tex]x^2 + y^2 =1[/tex]

For this solution, we assume y = 0

[tex]x^2 + 0^2 =1[/tex]

[tex]x^2=1[/tex]

Solve for x

[tex]x = 1[/tex]

So, the coordinates of C is: (1,0)

[tex]C = (1,0)[/tex]

Solving (b): Plot point E

We have that E is 4/5 closer to the origin.

This implies that, the ratio is:

[tex]m : n = 4/5:1/5[/tex]

Multiply by 5

[tex]m : n = 4:1[/tex]

So, E is at 4:1 between O and C

Calculate the coordinates of E using:

[tex]E = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]

Where

[tex]O= (0,0)[/tex] ---[tex](x_1,y_1)[/tex]

[tex]C = (1,0)[/tex] --- [tex](x_2,y_2)[/tex]

[tex]m : n = 4:1[/tex]

[tex]E = (\frac{4*1 + 1 * 0}{4 + 1},\frac{4*0 + 1*0}{4 + 1})[/tex]

[tex]E = (\frac{4}{5},\frac{0}{5})[/tex]

[tex]E = (0.8,0)[/tex]

Step-by-step explanation:

It has an initial charge of 2.50 dollars so you have to pay that before you calculate your miles which is 2.65x. X = the amount of miles you plug into the equation.

Answer:

(2, 5)

Step-by-step explanation:

The longest side of the triangle will be the side with the coordinate (1,4) and (3,6) due the value of the distance between them;

Midpoint = (x1+x2/2, y1+y2/2)

X = 1+3/2

X = 4/2

X = 2

Y = 4+6/2

Y = 10/2

Y = 5

Hence the required midpoint (X, Y) will be at (2, 5)

Answer:

y = -13

I like two step equations

Step-by-step explanation:

Equation :

18 = 5-y

Im just going to flip it around because it feels more comfortable

5-y = 18

Add y to both sides

5 = 18 + y

Subtract 18 from both sides

-13 = y

y = -13

If my answer is incorrect, pls correct me!

Answer:

$31.43

Step-by-step explanation:

If you take 15% of 36.99 you get around 5.56. So all you have to do is subtract that from the original amount.

Answer:

4, 20, 2

Step-by-step explanation:

The relationship between x and y is multiplication by 4:

9*4 = 36

4*4 = 16

5*4 = 20

2*4 = 8

Answer:

hi!

your answer would be 4, 20, 2

Answer:

$144

Step-by-step explanation:

Volume of the pyramid = 1/3BH

Base area B = 1/2 * 6 * 4

Base area B = 12 ft²

Height H = 4ft

Volume of the pyramid = 12 * 4

Volume of the pyramid = 48ft³

SInce 1 ft³ = $3

48ft³ = x

Cross multiply

x = 3 * 48

x = 144

Hence the cost of the sign is $144

Q: You are shot out of a cannon at the fair. The equation y=-1/5 * (x+2) (x-28) models your flight path, where y is the height above the ground and x is the horizontal distance. Which of the following statements in the comments are true?

a) You reach a maximum height of 45 feet,

b) You will land 11.2 feet from the cannon,

c) The barrel of the cannon is about 11 feet above the ground.

d)At a point 13 feet from the cannon, you begin to descend.

A: When y = 0, x = 28

y’ = 0 at x = 13 where Y is max = 15^2 / 5 = 45

Hence a is true, b is false, c is false, d is false .

Step-by-step explanation:

You will first add all the students the mentioned which gives you 13 then since they ask what is the probability it the teacher would pick girls. You know there's 10 girls and 3 boys so it would be 10/13.                                  

Answer:

5. Obtuse 6. Right 7. Straight 8. Acute 9. Acute 10. Right

so quick explanation acute is smaller than 90 degrees right angle is exactly 90 degrees an obtuse angle is over 90 degrees and a straight angle is 180 degrees also straight

Answer:

x = 9

y = [tex]9\sqrt{2}[/tex]

Step-by-step explanation:

Since there is a 45° angle and a 90° angle, this is a isosceles triangle, therefore x = 9 and you can find y by pithagoras:

9² + 9² = y²

81 + 81 = y²

y = [tex]\sqrt{162}[/tex]

[tex]y=\sqrt{2 * 81}[/tex]

[tex]y=\sqrt{2 * 9^2}[/tex]

[tex]y=9\sqrt{2}[/tex]

Step-by-step explanation:

=================================================

Explanation:

The sine ratio involves the opposite side over the hypotenuse

For reference angle E, the opposite side is the unknown vertical side, which we'll call x for now.

The known leg is 99 and the known hypotenuse is 101. We'll use these two bits of info to find x. Apply the pythagorean theorem:

a^2 + b^2 = c^2

x^2 + 99^2 = 101^2

x^2 + 9801 = 10201

x^2 = 10201-9801

x^2 = 400

x = sqrt(400)

x = 20

The missing vertical side of the triangle is 20 units. Now we can apply the sine ratio to find sin(E)

sin(angle) = opposite/hypotenuse

sin(E) = 20/101

This fraction cannot be reduced further. This is because 20 = 2*2*5, and neither 2 nor 5 is a factor of 101.

Answer:

57 miles per hour

Step-by-step explanation:

Find his average speed by dividing the total of miles he traveled by the number of hours:

456/8

= 57

So, this means he traveled 57 miles in one hour.

His average speed was 57 miles per hour
