Step-by-step explanation:

sin(-184) is the equivalent to sin(4) (degree), positive and acute angle.

Using it's concept, it is found that the probability of an odd number other than seven being generated is of 40.0%.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

For an experimental probability, these number of outcomes are taken from previous trials.

In this problem, 200 numbers have been generated, and 80 are odd numbers that are not seven, hence the probability is given by:

p = 80/200 = 0.4 = 40%.

Answer:

The intersection is at (1,3) and the answer is in the graph. (see image below)

Step-by-step explanation:

Answer:

An angle whose measure is equal to 90° is called a right angle.

An angle whose measure is more than 0° but less than 90° is called an acute angle. Angles having magnitudes 30°, 40°, 60° are all acute angles.

An angle more than 90 degrees and less than 180 degrees, is called an obtuse angle.

The general solution to the differential equation is y = sinx + c cosx.

It is defined as the equation which contains functions, derivative of the functions to make an expression.

We have a differential equation:

[tex]\rm cosx\left(\dfrac{dy}{dx}\right)+\left(sinx\right)y\:=\:1[/tex]

Multiply by dx:

(cosx) dy + (sinx) y dx = dx

(cosx) dy = (1 - (sinx) y) dx

After simplification and integrating, we will get:

[tex]\rm y = \dfrac{tan x}{sec x}+ \dfrac{c}{secx}[/tex]

y = sinx + c cosx

Thus, the general solution to the differential equation is y = sinx + c cosx.

Using proportions, it is found that 804.54 pounds of vegetables will be transported to the market in August.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

In this problem, considering the weight increases by 15% every month, the August amount will be the July's amount multiplied by 1.15, hence:

A = 1.15 x 699.60 pounds = 804.54 pounds.

Answer:

Step-by-step explanation:

x² - 14x - 15 = x² - 14x + (49 - 49) - 15

                  = (x² - 14x + 49) - 49 - 15

                  =  (x² - 14x + 7²) - 49 - 15

                  =  (x − 7)² − (49 + 15)

                  =  (x − 7)² − 64

x² - 14x - 15 =  (x − 7)² − 64

Then the coordinates of the vertex are (7 , -64)

Answer : Length(l) = 32 cm

Step-by-step explanation:

Given,

          Perimeter(P)=96 cm

          Length(l)=?

We know that,

                        P      = 3l

                        96    = 3l

                        96÷3 = l

                         32    = l

Therefore, length(l) = 32 cm

Answer:

5:9

Step-by-step explanation:

the circumference is d*pi

so you must find the diameter of both circles

31/pi = 9.86760647

which is about 10

57/pi = 18.1436635

which is about 18

10:18 is your ratio

but you can simplify this down to

Using a trigonometric realtion, we can see that x = 23.18cm

Here we have a right triangle, we can see that y = 6cm, and the angle theta is 15°.

Notice that y is the opposite cathetus to the known angle, and we want to find the value of x, which is the hypotenuse.

Then we can use the trigonometric relation:

sin(a) = (opposite cathetus)/hypotenuse.

Reaplacing what we know, we will get:

sin(15°) = 6cm/x

Solving that for x:

x = 6cm/sin(15°9

x = 23.18cm
