The amount of defects is not the independent value since you can not choose how many are defects, the independent variable would be the amount of bread made.

The slope of the tangent line for the curve r=2 cos(3 theta) where theta = pi/6 is.
Phantasy [73]

as you already know, the slope of the tangent line is simply the derivative of the function, so

r=2cos(3\theta )\implies \cfrac{dr}{d\theta }=2\stackrel{chain~rule}{\left[ -sin(3\theta )\cdot 3 \right]} \\\\\\ \left. \cfrac{dr}{d\theta }=-6sin(3\theta ) \right|_{\theta =\frac{\pi }{6}}\implies -6sin\left( 3\cdot \frac{\pi }{6} \right)\implies -6sin\left( \frac{\pi }{2} \right)\implies -6

The area of the right triangle shown is 30 ft squared. The segment XY has a length of 5 ft. Find the length of the hypotenuse.
alexgriva [62]

Answer:

Hypotenuse is 13 ft.

Step-by-step explanation:

A=(1/2)bh

30=(1/2)(5)(h)

30=2.5h

h=12  so ZY = 12ft

Then

a^{2} +b^{2} =c^{2} \\5^{2} +12^{2} =c^{2} \\25+144=c^{2} \\169=c^{2}\\13=c

An ant moves 18 millimeters every 5 seconds
vaieri [72.5K]

Answer:

Step-by-step explanation:

First we need to find their rate of speed.

r = d / t

For ant,

Convert millimeters to inches.

1 inch = 25.4 mm

18 mm = 0.7 inch

r = 0.7 / 5

r = 0.14 inches per second

For beetle,

r = 8 / 3

r = 2.7 inches per second

From the rates, you can tell that the beetle crosses the Garden first.

To know how long it takes for the ant to cross is by dividing the length by the rate.

1 yard = 36 inches

13 yards = 468 inches

468 ÷ 0.14 = 668.5 ≈ 669 seconds

In terms of minutes:

11 minutes and 15 seconds

The ant would cross the garden in 11 minutes and 15 seconds (or 669 seconds <em>up to you</em>).

Eli buys 8 gigabytes of memory for his computer he spends 392. whatbis the cost of 1 gigabyte memory
kotykmax [81]
If Eli spends $392 for 8 gigabytes of memory, then 8g=392, where g is a gigabyte of memory. All you have to do is to reduce the equation. In this case, divide both sides by 8 to get g=49. So the cost of 1 gigabyte of memory is $49.

The RANGE of the function f is
monitta

Answer:

Step-by-step explanation:

The range of the function is what values of y from lowest to highest that are covered by the function.  The domain are the values on the left: A-E; the range are the values on the right: 1-3.  We state both domain and range in interval notation, stating only the lowest and highest values in either a set of brackets if the values are included, a set of parenthesis if the values are not included, or a mixture of both.  Our range is inclusive, so we mention the lowest and the highest only: [1, 3].
