Answer:

The equation is given by:

n = \frac{7}{10} \times 45.50

Step-by-step explanation:

During last years's charity walk, she raised $45.50.

During this years walk, she raised n, which is 7/10 of this amount. So, the equation is given by:

n = \frac{7}{10} \times 45.50

Answer:

The answer to this problem would be A.

Step-by-step explanation:

For childcare facilities for each visit is $9, we would say 9x because we dont know the exact amount of time that she visits the gym with her child. Her monthly gym bill is $32 which would ve added to the amount she would pay for childcare. The sum of it all should be less than or equal to that of $122.

Please help, this chapter was on derivatives...
weqwewe [10]

(3) Differentiating both sides of

2x^{3/2} + y^{3/2} = 29

with respect to <em>x</em> gives

3x^{1/2} + \dfrac32 y^{1/2} \dfrac{\mathrm dy}{\mathrm dx} = 0

Solve for d<em>y</em>/d<em>x</em> :

\dfrac32 y^{1/2} \dfrac{\mathrm dy}{\mathrm dx} = -3x^{1/2} \\\\ \dfrac{\mathrm dy}{\mathrm dx} = \dfrac{-3x^{1/2}}{\frac32y^{1/2}} = \dfrac{-2x^{1/2}}{y^{1/2}} = -2\sqrt{\dfrac xy}

Then the slope of the tangent line to the curve at (1, 9) is

\dfrac{\mathrm dy}{\mathrm dx} = -2\sqrt{\dfrac19} = -\dfrac23

The equation of the tangent line would then be

<em>y</em> - 9 = -2/3 (<em>x</em> - 1)   ==>   <em>y</em> = -2/3 <em>x</em> + 29/3

(4) The slope of the tangent line to

y=\dfrac{ax+1}{x-2}

at a point <em>(x, y)</em> on the curve is

\dfrac{\mathrm dy}{\mathrm dx} = \dfrac{a(x-2)-(ax+1)}{(x-2)^2} = -\dfrac{2a+1}{(x-2)^2}

When <em>x</em> = -1, we have a slope of 2/3, so

-(2<em>a</em> + 1)/(-1 - 2)² = 2/3

Solve for <em>a</em> :

-(2<em>a</em> + 1)/9 = 2/3

2<em>a</em> + 1 = -18/3 = -6

2<em>a</em> = -7

<em>a</em> = -7/2

Need help can someone plz help me solved this problem ASAP! Need help I will mark you as brainiest
MrRissso [65]

Answer:  2, 6

<u>Step-by-step explanation:</u>

Triangle Inequality Theorem states that the sum of two sides must be GREATER than the third side.

RS + ST > RT    and     RS + RT > ST     and     ST + RT > RS

2x + 4x > 12                  2x + 12 > 4x                  4x + 12  > 2x

       6x > 12                          12 > 2x                          12  > -2x

         x > 2                            6 > x                             -6 < x

         2 < x                             x < 6                             invalid

Answer:  2 < x < 6      

Graph:     O----------------------O

                2                          6

<em> Note: -6 is invalid because you cannot have a negative length. </em>

Jasmine adds sugar to his coffee at a ratio of 10g:250mL.
TEA [102]

Answer:

12 grams of sugar

Step-by-step explanation:

For every gram of sugar, there is 25mL of coffee, so using that knowledge, you can divide the 300mL by the 25mL, and that is how many grams of sugar Jasmine uses.
