Answer:

r is usually the radius but can also be a variable, in this case r = -189

Step-by-step explanation:

Solve for r:

-13 = r/9 + 8

Put each term in r/9 + 8 over the common denominator 9: r/9 + 8 = r/9 + 72/9:

-13 = r/9 + 72/9

r/9 + 72/9 = (r + 72)/9:

-13 = (r + 72)/9

-13 = (r + 72)/9 is equivalent to (r + 72)/9 = -13:

(r + 72)/9 = -13

Multiply both sides of (r + 72)/9 = -13 by 9:

(9 (r + 72))/9 = -13×9

(9 (r + 72))/9 = 9/9×(r + 72) = r + 72:

r + 72 = -13×9

9 (-13) = -117:

r + 72 = -117

Subtract 72 from both sides:

r + (72 - 72) = -72 - 117

72 - 72 = 0:

r = -72 - 117

-72 - 117 = -189:

Answer: r = -189

Answer:

y=6cos 45° +4

  =6(1/√2)+4

   =6/√2+4

Step-by-step explanation:

y=acosx+b

find a and b

y=b=4 when x=90 degrees because cos 90=0

find a : when x=60 degrees, y=7

7=acos60°+4

7=a(1/2)+4

a/2=3

a=6

y=6cos 45° +4

  =6(1/√2)+4

   =6/√2+4

Complete Question:

Suppose a local vendor charges $2 per hot dog and that the number of hot dogs sold per hour is given by [tex]x(t) = -4t^2 + 20t + 60[/tex], where is the number of hours since 10 AM:

a) Find an expression for the revenue per hour as a function of x, R(x)

b) Find and simplify, R(x(t))

Answer:

a) R(x) = 2x

b) [tex]R(x(t)) = -8t^2 + 40t + 120[/tex]

Step-by-step explanation:

a) This is a very trivial exercise.

[tex]x(t) = -4t^2 + 20t + 60[/tex]

The number of hot dogs sold per hour is given by x

Charge per hot dog = $2

An expression of revenue per hour,R, as a function of the number of hot dogs sold per hour, x, is therefore: R(x) = 2x

b) [tex]x(t) = -4t^2 + 20t + 60[/tex]

R(x(t)) = 2(x(t))

[tex]R(x(t)) = 2(-4t^2 + 20t + 60)\\R(x(t)) = -8t^2 + 40t + 120[/tex]

Answer:

- 4096

Step-by-step explanation:

There is a common ratio between consecutive terms of the sequence.

r = - 4 ÷ 2 = 8 ÷ - 4 = - 2

This indicates the sequence is geometric with n th term

[tex]a_{n}[/tex] = a [tex]r^{n-1}[/tex]

where a is the first term and r the common ratio

Here a = 2 and r = - 2 , thus

[tex]a_{12}[/tex] = 2 × [tex](-2)^{11}[/tex] = 2 × - 2048 = - 4096

Answer:-4096

Answer:

Step-by-step explanation:

hello,

ab = 0 <=> a = 0 or b = 0

so

(x+3)(x-4)=0 <=> x+3 = 0 or x-4 = 0 <=> x = -3 or x = 4

(2x-3)(x-1)=0 <=> 2x-3=0 or x-1 = 0 <=> x = 3/2 or x = 1

hope this helps

Answer:

B) y = -3 sin(2(x + π/4)) - 2

Step-by-step explanation:

Which function is the same as y = 3 cos(2 (x + π/2)) - 2

A)  y = 3 sin(2(x + π/2)) - 2

B) y = -3 sin(2(x + π/4)) - 2

C) y = 3 cos(2 (x + π/4)) - 2

D) y = -3 cos(2 (x + π/2)) - 2

y = 3 cos(2 (x + π/2)) - 2

Sine and cosine have the following relationship:

cos(θ) = sin (π/2 - θ)

y = 3 cos(2 (x + π/2)) - 2

⇒ y = 3 cos(2x + π) - 2

Let θ = 2x + π, therefore using Sine and cosine have the following relationship:

cos(2x + π) = sin (π/2- (2x + π))

= sin (π/2 - 2x - π)

= sin (-2x - π/2)

= sin (-2(x + π/4))

but sin(-θ) = -sin (θ)

Therefore:

sin (-2(x + π/4)) = -sin (2(x + π/4))

⇒ - sin (2(x + π/4)) = cos(2x + π)

y = 3 cos(2x + π) - 2 = 3[ - sin (2(x + π/4))] -2

y = -3 sin (2(x + π/4)) -2

Answer:

She needs 78 inches of fabric.

Step-by-step explanation:

The rule for the amount of fabric that needs to be bought is:

[tex]\text{fabric} = 2*x + 8[/tex]

Where "x" is the distance from the waist to the finished length of the pants. Since Amy's is 35 inches, the amount of fabric is:

[tex]\text{fabric} = 2*35 + 8\\\text{fabric} = 70 + 8\\\text{fabric} = 78 \text{ inches}[/tex]

She needs 78 inches of fabric.

Add this to make a perfect square trinomial

x^2 -10x+25

Answer:

Y = 170, Z = 64.

Step-by-step explanation:

Since y is the external angle to x, which you got right, it is in fact, 180-10, = 170 degrees. And since z is the external to our unknown angle, that means it is equal to the sum of the other two angles in the triangle. That means z is 54 + 10, which is 64.

Answer: 1.0x10^9

Step-by-step explanation:

first, one million is:

1,000,000

you can count that we have six zeros, so in scientific notation this is:

1.0x10^6

one thousand is 1,000

we have 3 zeros, so in scientific notation this is:

1.0x10^3

Then, the product of these numbers is:

1.0x10^3*1.0x10^6 = (1.0*1.0)x10^(3 + 6) = 1.0x10^9

Answer:

The magnitude of the boat's velocity is 5.66 m/s

Step-by-step explanation:

Given;

Radius of curvature of the circular path, r = 40 m

speed of the boat, v = 0.8 t m/s

The magnitude of the boat's velocity when it has traveled 20 m is ?

a = dv / dt,

v = 0.8 t (differentiate with respect to t)

dv / dt = 0.8 = a

thus, a = 0.8 m/s²

If the boat starts from rest, initial velocity, u = 0

Apply kinematic equation, to solve for the boat velocity at 20 m

v² = u² + 2as

v² = 0 + 2 x 0.8 x 20

v² = 0 + 32

v² = 32

v = √32

v = 5.66 m/s

Therefore, the magnitude of the boat's velocity when it has traveled 20 m is 5.66 m/s

Answer:

Translation up 3 units

Step-by-step explanation:

The equation f(x)=x goes through the origin.

f(x)+3 is exactly the same, except that it is translated up 3 units on the graph.

Answer: (-13, -3), (-1, 0), and (7, 2).

Step-by-step explanation:

First, we have a function f(x) and we know that 3 points (x, y) of this function are:

(-3, -13), (0, -1), and (2, 7).

Now, if we have a function g(x) and we know that g(x) is the inverse of f(x), we have that:

g(f(x)) = x.

this means that if f(x) = y then g(y) = x.

then if (-3, -13) is a point in the f(x) graph, (-13, -3) must be a point in the g(x) graph.

Then 3 points in on the inverse of the function f(x) are:

(-13, -3), (-1, 0), and (7, 2).
