A coordinate grid is mapped onto a video game screen, with the origin at the lower left corner. The game designer programs a tur

tle to move along a linear path that passes through the points (0, 0) and (10, 8).The designer also programs a bird with a path that can be modeled by a quadratic function. The bird starts at the vertex of the path at (0, 20) and passes through the point (10, 8).What is the slope of the line that represents the turtle's path?

Answer: 0.8

Step-by-step explanation:

The slope of a line passing through point A(a,b) and B(c,d) is given by :-

m=\dfrac{d-b}{c-a}

Given : A coordinate grid is mapped onto a video game screen, with the origin at the lower left corner.

The game designer programs a turtle to move along a linear path that passes through the points (0, 0) and (10, 8).

Then , the slope of the line that represents the turtle's path is given by :-

m=\dfrac{8-0}{10-0}=\dfrac{8}{10}=0.8

Hence, the slope of the line that represents the turtle's path is 0.8 .

Addison studies a tarantula that is 30 mm long suppose she uses a microscope to magnify the spider by 4×10 to the second power h
Debora [2.8K]
The magnification factor is given as 4(10)^2=400. Therefore multiplying this by the spider's actual length will give its apparent length.(400)(30 mm) = 12,000This gives an apparent length of 12,000 mm.
Since 1,000 mm = 1 m, this apparent length is also equivalent to 12 m.

Find the points on the curve where the tangent line is horizontal . x=4(cosθ-cos^2θ) , y=4(sinθ-sinθcosθ)
taurus [48]
X = 4(cosθ - cos²θ) = 4cosθ - 4cos²<span>θ
</span>dx/dθ = -4sinθ + 8sinθcosθ = -4sinθ(1 - 2cos<span>θ)

dy/d</span>θ = 4(cosθ - cos²θ + sin²θ) = 4(cos<span>θ - 1)

</span>∴dy/dx = 4(cosθ - 1)/-4sinθ(1 - 2cosθ) = 1-cosθ/(sinθ - 2sinθcosθ<span>)
Now, we're finding a horizontal tangent, which is when dy/dx = 0 (horizontal tangent).
1-cos</span>θ/(sinθ - 2sinθcosθ) = 0
1-cosθ = 0
cosθ = 1

θ = 0, 360 in the interval [0, 360].
At θ = 0, x = 0, y = 0

Only points in the open interval [-2π, 2π] are at (0, 0), unless I made a mistake somewhere.

Two mechanics worked on a car. The first mechanic charged $45 per hour, and the second mechanic charged $55 per hour. The mechan
Rus_ich [418]
Let first mechanic worked for X and second be Y.

So, X + Y = 25
X = 25-Y

And total they charged-
45X + 55Y = 1175
5 (9X + 11Y) = 235 * 5
(9X + 11Y) = 235
11Y = 235-9X

From fist statement: X=25-Y

11Y = 235-9(25-Y)
11Y = 235-225+9Y
11Y = 10+9Y
11Y - 9Y = 10
2Y = 10
Y= 10/2
Y=5 hours

X=25-Y
X=25-5
X=20

X worked for 20 hours and Y for 5 hours.

PS. Moral of the story- You can say Y was lazy but still charged more than Y. Just kidding!
