C(t)=4t($25)+$200
The reason we put a 4 before the t($25) is because with the $200 it states that that’s the price for 4 months, so we know that the time has to be by a factor of 4 because you have to pay the gym membership every 4 months.

Answer:

we have to find the quotient and the remainder when (x³ + 5x + 3x² + 5x³ + 3) is divided by (x² + 4x + 2) ♥9 dividend = x² + 4x + 2 using Euclid division lemma, x² + 4x + 2) x² + 5x³ + 3x² + 5x + 3(x³ - 4x² + 19x - 65 x² + 4x² + 2x³ - 4x² + 3x² + 3x² - 4x*-16x³8x² 19x³ + 11x² + 5x 19x³ +76x² + 38x -65x²-33x + 3 -65x²-260x - 130 +227x + 133 Therefore the quotient is x² - 4x + 19x - 65 and remainder is 227x + 133

HELP &lt;3 Match the expressions with their solutions.
densk [106]

Answer:

1 ) sin 165°

2 ) cos 330°

3 ) Tan 157.5°

4 ) sin^2 157.5

Step-by-step explanation:

1 )

Given expression is  \sqrt{\frac{1-cos330}{2} }

We know that cos2x=1-2sinx^{2}

sinx^{2}=\frac{1-cos2x}{2}

(sinx/2)^2=\frac{1-cosx}{2}

So the first expression is sin (330/2)° =sin 165°

2 )

GIven expression is  1-2sin^2165

We know that cos2x=1-2sinx^{2}

So the result is cos 330°

3 )

Given expression is \frac{1-cos 315}{sin315}

We know that cos2x=1-2sinx^{2}

Also we know that sin2x = 2sinxcosx

So The numerator becomes 2sin^2x/2. and the denominator becomes as 2sinx/2cosx/2

\frac{2sin^2x/2}{2sinx/2cosx/2}=tanx/2

So the result is Tan 157.5°

4 )

Given expression is \frac{1-cos 315}{2}

We know that cos2x=1-2sinx^{2}

(sinx/2)^2=\frac{1-cosx}{2}

So the result is sin^2 157.5

Write an equation of the line that has a slope of 2 and contains the point (1, 1) in point-slope form.
exis [7]
Point-slope form: we need a point (x₀,y₀) and the slope "m".
y-y₀=m(x-x₀)

Data:
(1,1)
m=2

Therefore:
y-y₀=m(x-x₀)
y-1=2(x-1)    This is the equation of the line in point-slope form.

Answer.    y-1=2(x-1)

when looking at a rational function f of x equals the quantity x plus three times the quantity x minus two times the quantity x
almond37 [142]
f(x)= \frac{(x+3)(x-2)(x+5)}{(x-3)(x+2)(x-5)} is undefined when the denominator is 0. i.e. x - 3 = 0 or x + 2 = 0 or x - 5 = 0 i.e. x = 3 or x = -2 or x = 5.
Hence, Bobby is right.
