Answer:

The equation of the line is [tex](x(t),y(t))=(1-4t,2+6t)[/tex] and the equation of the circle is [tex]F(t)= (3cos(t)+4,3sin(t)+1)[/tex].

Step-by-step explanation:

(a) Given: The given points are [tex](1,2)[/tex] and [tex](-3,8)[/tex].

To find: The parametric equation of line containing points [tex](1,2)[/tex] and [tex](-3,8)[/tex].

We know that the parametric equation of line containing [tex](x_{1} ,y_{1} )[/tex] and [tex](x_{2} ,y_{2} )[/tex] is given by [tex](x(t),y(t))=(x_{1}+(x_{2}-x_{1})t,y_{1}+(y_{2}-y_{1})t)[/tex] where [tex]t[/tex]∈[tex][0,1][/tex].

Now, [tex]x(t)=1+(-3-1)t[/tex]

i.e, [tex]x(t)=1-4t[/tex]

And, [tex]y(t)=2+(8-2)t[/tex]

i.e, [tex]y(t)=2+6t[/tex]

Hence, the required parametric equation of the line is [tex](x(t),y(t))=(1-4t,2+6t)[/tex].

(b) Given: The radius of circle is 3 and centre is [tex](4,1)[/tex].

To find: The parametric equation of circle with radius 3 and centre [tex](4,1)[/tex].

We know that parametric equation of circle with radius [tex]r[/tex] and centre [tex](h,k)[/tex] is given by [tex]F(t)= (x(t),y(t))[/tex] where [tex]x(t)=rcos(t)+h[/tex] and [tex]y(t)=rsin(t)+k[/tex].

Now, [tex]x(t)=3cos(t)+4[/tex]

[tex]y(t)=3sin(t)+1[/tex]

So, the parametric equation of circle having radius 3 and centre [tex](h,k)[/tex] is [tex]F(t)= (3cos(t)+4,3sin(t)+1)[/tex].

Hence, the required equation of the circle is [tex]F(t)= (3cos(t)+4,3sin(t)+1)[/tex].

Answer:

D

Step-by-step explanation:

8^2 +12^2 = hyp ^2

64 +144 = hyp^2

208 =hyp ^2

Hyp = 4 root 13

x = sqaureroot of ( 18^2 + (4 root 13)^3)

x = sqaureroot of (324 +208)

x = sqaureroot of 532

x = 2 root 133

x = 23.065

x = 23

Please gimme brainliest

i think the answer is sixty-five

Step-by-step explanation:

i assume this is the question you asked me to look at.

Well, angle 116° and y are supplementary angles

therefore,116°+y=180°

y=180°-116°=64°

Now to find x

x+y+125+72=360°

x+64+125+72=360

x+261=360

x=360-261=99°

The measure of x° is  99° and the measure of y° is 64°.

What is quadrilateral?

A quadrilateral is a polygon with four sides four angles and four vertices. Whenever we name a quadrilateral, we need to keep in mind the order of the vertices.

From the given figure,

116°+y°=180° (Sum of adjacent angles is 180°)

y°=180°-116°

y°=64°

Sum of interior angles of quadrilateral is 360°.

Here, x°+y°+72°+125°=360°

x°+64°+72°+125°=360°

x°+261°=360°

x°=99°

Therefore, the measure of x° is  99° and the measure of y° is 64°.

Answer:

Cassie bought 0.375 pounds of peanuts and 0.250 pounds of cashews, that is, she bought 50% more peanuts than cashews.

Step-by-step explanation:

Since Cassie bought 3/8 of a pound of peanuts and 1/4 of a pound of cashews, to determine the comparison between both nuts the following calculation must be performed:

3/8 = pounds of peanuts

0.375 = pounds of peanuts

1/4 = pounds of cashews

0.250 = pounds of cashews

Therefore, Cassie bought 0.375 pounds of peanuts and 0.250 pounds of cashews, that is, she bought 50% more peanuts than cashews.

Answer:

Step-by-step explanation:

Probability is the possibility for an event to occur or not to occur.

The formula for a combination is:

n choose r = n! / (r! x (n-r)!)

Given

n=14

r= 11 to 13

Hence, we shall add up the cases for 11 through 13.

nCr

14C11 + 14C12 + 14C13

14!/11!(14-11)! + 14!/12(14-12)! + 14!/13(14-13)!

= 14!/11!•3! + 14!/12!•2! + 14!/13!•1!

= 14*13*12*11!/11!•(3*2*1) + 14*13*12!/12!•(2*1) + 14*13!/13!•(1*1)

= 2184/6+182/2+14/1

= 364+91+14

Answer:

Step-by-step explanation:

First you put all the variables with a negative exponent to the opposite side of the fraction, with the answer of 45m^2p^2v^16/15m^6p^8. You then simplify, or cancel out until the variable only remains on one side of the fraction. 3v^16/m^4p^6. So your answer is B
