if the slop of the straight line passing through the two points A (4, k) , B (3, 2) is 5, find the value of K

Answers

Answer 1

Answer:

Step-by-step explanation:

*The dashes are the fraction line*

To find slope...

difference between y

-------------------------------

difference between x

2 - k

-------  =  5

3 - 4

3-4 = -1 so...

-1 ( 2 - k ) = 5

k - 2 = 5

k = 7

Hope this helps!

Answer 2

Answer:

2.5 or 5/2

Step-by-step explanation:

Y2-Y1/X2-X1=m

(2-k)/(3-4)=5

(2-k)/-1=5

Multiply both sides by -1

(2-k)/2=-2.5

-k/-1=-2.5/-1

k=2.5 or 5/2

I believe
y (theta) = 3 sin t
and
a(theta) = 3 cos t
but that might be wrong because I'm so confused. Please Please help!

Answers

Step-by-step explanation:

sintheta=y/3"

theta=sin-¹(y/3")

cos theta=a/3"

theta=cos-1(a/3)

sin beta=y/7"

beta=sin-¹(y/7")

b=√{y²+7" ²}

sorry last one I don't know

Answer:

sinθ = y/3                        ⇒ y(θ) = 3 sinθcosθ = a/3                       ⇒ a(θ) = 3 cosθsin β = y/7 = 3 sinθ / 7    ⇒ β(θ) = arcsin (3/7sinθ)b(θ) = √(7²-y²) = √(49-9sin²θ)p(θ) = a(θ) + b(θ) = 3 cosθ + √(49-9sin²θ)

The graph is attached

---------------------------------------

p.s.

b(θ) can be put in different way:

cos β = b/7 ⇒ b(θ) = 7 cos β = 7cos(arcsin(3/7sinθ))

Then

p(θ) = a(θ) + b(θ) = 3 cosθ + 7cos(arcsin(3/7sinθ))

This doesn't change the function or the graph

Answer:

x = 4√3, or approximately 6.93

Step-by-step explanation:

This is a right triangle with hypotenuse 13 and side lengths x and 11.  According to the Pythagorean Theorem, x^2 + 11^2 = 13^2 = 169, or

x^2 + 121 = 169, or

x^2 = 48.

x must be a positive quantity.  Thus, x = +√48 = + √3·√16 = +4√3

Thus, x = 4√3, or approximately 6.93

Find (3x+1)(x+4) using the table of products. Write your answer in standard form.

Answers

Step-by-step explanation:

just multiply both the values and get the quadratic solution.

The standard form of the (3x+1)(x+4) is 3x^2+13x+4=0.

We have given that,

(3x+1)(x+4) using the table of products.

We have to determine the standard form.

What is the formula of the standard form?

The quadratic function f(x) = a(x - h)2 + k, a not equal to zero, is said to be in standard form. If a is positive, the graph opens upward, and if a is negative, then it opens downward. The line of symmetry is the vertical line x = h, and the vertex is the point (h,k).

ax^2+bx+C=0

[tex]=3xx+3x\cdot \:4+1\cdot \:x+1\cdot \:4[/tex]

[tex]=3x^2+13x+4[/tex]

Therefore the standard form is 3x^2+13x+4=0.

Step-by-step explanation:

The general equation is

y = 2.49x + 24.99

The number of cones bought is x

The cake cost is 24.99

The total cost is y

===========

So the meaning of (5,37.44) is that she bought 5 cones and 1 cake. Let's just check that out.

Check

y = 2.49*5 + 24.99

y = 12.45 + 24.99

y = 37.44

So the total cost (y) of 5 cones (2.49 each) and 1 cake ($24.99) is 37.44

They do not believe that Apollo is Phathons father or that Apollo makes the sun rise and set. In order to prove Phathon s friends wrong, Apollo hesitantly gives Phathon his chariot and horses. Apollo hurried to give directions. You have never driven my chariot before. You must make the horsesstay on the path. If you are too low, you will scorch the earth. I know, Father. Now watch me take off! shouted Phathon. Dawn stepped back and released her grip on the horses bridles. The horses pawed the ground and snorted with excitement. The sky begged for Dawns light, so she ran toward the horizon in her glowing gown to make the darkness fade. As Phathon was about to ascend, Apollo grabbed his arm and said, Please listen to me! If you go too high, you will warm the cold depths of the heavens, and the Bear or Snake or Scorpion will come alive! Phathon just laughed. My friends are waiting. Ive got to go! he shouted. With that, the chariot was off. It was a wild ride. Hour and Day were unruly and difficult to control. Phathon did not have his fathers strong arms or years of experience. The horses wove from side to side and bobbed up and down through the heavens, hitting everything in their way. The sun bounced along behind the chariot like a basketball. It grazed the stars and skidded along mountaintops, leaving charred remains behind. Phathons friends ran for cover as they watched the spectacle. Just as his father had warned him, the figures in the sky began to move. Suddenly the Scorpion lunged toward him, but Phathon ducked out of the way in time. The Snake lashed out and bit a wheel off the chariot. Apollo, witnessing the destruction, dashed up toward the heavens, but he was too late! The Bear had stirred from his icy hibernation and grabbed Phathon before his father could reach him. Apollo grabbed the reins and finally regained control of Hour and Day, but it was years before the earths mountaintops were white with snow again. The scorched areas became deserts where very little would grow. Phathon became a part of the constellations alongside the Bear, where his father could regretfully keep an eye on him.
