Answer:

Kim has the highest pay rate in dollars per hour

Step-by-step explanation:

we know that

To find out the unit pay rate divide the total earning by the total time

Nina earns $117.60 for hours 14 of work

$\frac{117.60}{14}=\$8.4\ per\ hour$

Ty earns for $148.50 hours 18 of work

$\frac{148.50}{18}=\$8.25\ per\ hour$

Kim earns for $137.60 hours 16 of work

$\frac{137.60}{16}=\$8.60\ per\ hour$

$8.6 > 8.4 > 8.25$

therefore

Kim has the highest pay rate in dollars per hour

Answer:

2) -81t² +16

Step-by-step explanation:

(9t -4)(-9t -4) = (9t x -9t) + (9t x -4) + (-4 x -9t) + (-4 x -4)

= -81t² - 36t + 36t + 16

= -81t² + 16

Find a cartesian equation for the curve. r = 9 sin(θ)

Paul [167]

For this case we have the following equation:
r = 9 sin (θ)
In addition, we have the following change of variables:
y = r * sine (θ)
Rewriting the equation we have:
r = 9 sin (θ)
r = 9 (y / r)
r ^ 2 = 9y
On the other hand:
r ^ 2 = x ^ 2 + y ^ 2
Substituting values:
x ^ 2 + y ^ 2 = 9y
Rewriting:
x ^ 2 + y ^ 2 - 9y = 0
Completing squares:
x ^ 2 + y ^ 2 - 9y + (-9/2) ^ 2 = (-9/2) ^ 2
Rewriting:
x ^ 2 + 1/4 (2y-9) ^ 2 = 81/4
4x ^ 2 + (2y-9) ^ 2 = 81
Answer:
The Cartesian equation is:
4x ^ 2 + (2y-9) ^ 2 = 81

Let

x ----> amount of 65 cents per pound flour to use

y----> amount of 95 cents per pound flour to use

we know that

$x+y=100$ ----> $y=100-x$ ----> equation A
