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

Step-by-step explanation:

Given

Missing dimensions:

[tex]Length = 15m[/tex]

[tex]Width = 8m[/tex]

[tex]Height = 12m[/tex]

Required

Determine the volume

Volume is calculated as:

[tex]Volume = Length * Width * Height[/tex]

This gives:

[tex]Volume = 15m * 8m * 12m[/tex]

Which number line shows all the values of that make the inequality -3 +1 < 7 true?

Answers

Answer:

Number line D is true

Step-by-step explanation:

Given

[tex]-3x + 1 < 7[/tex]

See attachment for number lines

Required

Which number line makes the inequality true

First, we solve for x in [tex]-3x + 1 < 7[/tex]

[tex]-3x < 7 - 1[/tex]

[tex]-3x < 6[/tex]

Divide through by -3

[tex]\frac{-3x}{-3} < \frac{6}{-3}[/tex]

[tex]x > -2[/tex]

The inequality means x is greater than -2.

This means that, the line must point to the right of -2 and the "greater than" means that the circle must be opened

What is function?

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is the expression as -

5 = h/1.25

We can solve for the value of {h} as -

5 = h/1.25

{h} = 5 x 1.25

{h} = 5 x 125/100

{h} = 125/20

{h} = 6.25

Therefore, on solving for the value of {h}, we get -

{h} = 6.25.

Can someone help me please

Answers

Answer:

height of b = 280

Step-by-step explanation:

candle b has a height of 280 - 5t, when it comes out of the mold then t=0 so the initial height of b is 280

candle b's height drops by 5 every hour (that's what the -5t part means)

candle a started at 216 and dropped to 192 in 3 hours, so it dropped by 24 in 3 hours so it drops 8 each hour

so candle b starts out taller (280 v. 216) and candle b burns slower (a at 8 per hour and b at 5 per hour), so b will never 'catch up' with a... candle a will be burned out while candle b is still burning

Three calculators cost as much as seven mugs. Each calculator costs $12 more than each mug. What is the cost of one mug?

Answers

Answer:

3.60

Step-by-step explanation:

3c=7m

c=m+12 solve for m

To obtain the value of one unknown quantity linear equation in one variable can be formed. The cost of one mug is given as $21.

What is a Linear equation?

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

Given that,

The cost of 3 calculators = The cost of 7 mugs.

The cost of each calculator is $12 more than each mug.

Suppose, cost of each mug be x.

And, cost of each calculator is x + 12.

As per the question the following equation can be made,

7 ×(x + 12) = 3x

=> 7x - 3x = 84

=> 4x = 84

=> x = 21.

Hence, the cost for one mug is $21.

47. The binding of erythropoietin to theerythropoietin receptor (EpoR) stimulatesintracellular signaling in certain cells, whichcauses them to differentiate to red blood cells.The EpoR is a transmembrane protein with twocytoplasmic domains, each of which is bound bya kinase protein, JAK2. The binding oferythropoietin to the EpoR causes thecytoplasmic domains of the EpoR to undergoconformational changes that activate the boundJAK2 kinases. The JAK2 kinases thenphosphorylate several intracellular proteins,including STATS, whose resulting activitycauses the cells to differentiate to red bloodcells.Which of the following explains how a mutationthat removes a portion of each cytoplasmicdomain of EpoR most likely affectsdifferentiation of the cells?(A) The cells will differentiate more rapidlythan they typically do because the JAK2kinases will always be active.(B) The cells will mature to another cell typebecause the JAK2 kinases willphosphorylate inappropriate cellularproteins.(C) STATS will not be activated becauseerythropoietin cannot bind to the EpoR.(D) STATS will not be activated because it willnot be phosphorylated by the JAK2kinases. what is the name of code or nucleotide squence that can be found in in dna, but not mrna and protein from the same gene What property is used to do-2y + 15 = -23 Create a problem with a quadratic equation that you would solve graphically and solve it.
