The Trigonometric functions sine (s) and cosine (c) c(5) ≈ -0.2837.

The trigonometric functions sine (s) and cosine (c). To determine s(5), we need to know the value of sine of 5 radians.

We can use a scientific calculator or a trigonometric table to find this value.

Using a calculator, we can simply enter "sin(5)" and get the answer. On most calculators, the answer will be displayed as a decimal.

Using a trigonometric table, we can look up the value of sine for 5 radians. The table will list the sine of angles in degrees, so we need to convert 5 radians to degrees first. One radian is equal to 180/π degrees, so

5 radians = (5 × 180)/π degrees ≈ 286.48 degrees

Looking up the sine of 286.48 degrees in the table, we get:

sin(286.48°) ≈ -0.9589

Therefore, s(5) ≈ -0.9589.

To determine c(5), we need to know the value of cosine of 5 radians.

We can again use a calculator or a trigonometric table to find this value.

Using a calculator, we can enter "cos(5)" to get the answer.

Using a trigonometric table, we can look up the cosine of 5 radians. Since we have already converted 5 radians to degrees, we can simply look up the cosine of 286.48 degrees in the table. We get:

cos(286.48°) ≈ -0.2837

Therefore, c(5) ≈ -0.2837.

Step-by-step explanation:

X goes left or right, while Y goes up or down. So, to move the triangle 6 units to the right, we take our current x coordinate, and add 6 to it.

Answer: 7.635 square meters

Step-by-step explanation:

Both triangles have the diameter as one of their sides and they both have a vertex on the circumference of the circle. Thus, the two triangles are right triangles, and the hypotenuse of the triangles is the diameter.

Use the Pythagorean Theorem: [tex]a^2+b^2=c^2[/tex]

Square root both sides to isolate c (hypotenuse/diameter): [tex]c=\sqrt{a^2+b^2}[/tex]

Plug in the values of a and b to calculate c: [tex]c=\sqrt{3^2+4^2}=\sqrt{9+16}=\sqrt{25}=5[/tex]

The diameter of the circle is 5 meters, so the radius of the circle is 2.5 meters.

Plug in the radius into the equation for the area of a circle: Area = [tex]\pi r^2=\pi *2.5^2=6.25\pi[/tex] square meters.

The equation for the area of a triangle is [tex]\frac{1}{2}bh[/tex], where b is the base of the triangle and h is the height of the triangle.

Since we have two congruent triangles, the total area of the two triangles combined is simply b*h.

Plug in the values of b and h to get b*h = 3*4 = 12 square meters.

Subtract the total area of the two triangles combined from the area of the circle to get the area of the shaded region: [tex]6.25\pi - 12=7.635[/tex] square meters.

Answer:

$839.20

Step-by-step explanation:

To find the finance charge, we need to first calculate the total amount financed, which is the price of the snow thrower minus the down payment.

The down payment is 20% of $1,501, which is:

0.20 x $1,501 = $300.20

So the total amount financed is:

$1,501 - $300.20 = $1,200.80

The total amount of the 12 monthly payments is:

12 x $170 = $2,040

The finance charge is the difference between the total amount of the payments and the amount financed:

$2,040 - $1,200.80 = $839.20

Therefore, the finance charge is $839.20.

Find the sum of the first six terms of the geometric sequence for which a2 = 0.7 and a3 = 0.49.

Let the common ratio of the geometric sequence be r. Then we have:

a2 = ar = 0.7

a3 = ar^2 = 0.49

Dividing the second equation by the first, we get:

r = a3/a2 = 0.49/0.7 = 7/10

So the first six terms of the sequence are:

a1 = a2/r = 0.7/(7/10) = 1

a2 = 0.7

a3 = 0.49

a4 = ar^2 = 0.343

a5 = ar^3 = 0.2401

a6 = ar^4 = 0.16807

The sum of the first six terms is:

S6 = a1 + a2 + a3 + a4 + a5 + a6

S6 = 1 + 0.7 + 0.49 + 0.343 + 0.2401 + 0.16807

S6 = 2.94017

Therefore, the sum of the first six terms of the geometric sequence is approximately 2.94017.

Rewrite using radicals.

The expression (x^3/4)^2 can be rewritten as:

(x^3/4)^2 = x^3/4 * x^3/4

(x^3/4)^2 = (x^3)^2 / 4^2

(x^3/4)^2 = x^6 / 16

So (x^3/4)^2 is equivalent to (x^6/16) using radicals.

Rewrite using rational exponents.

The expression √(a^3b^2) can be rewritten using rational exponents as:

√(a^3b^2) = (a^3b^2)^(1/2)

√(a^3b^2) = a^(3/2)b^(1)

So √(a^3b^2) is equivalent to a^(3/2)b^(1) using rational exponents.

The net force on the knot is 42.7 N. Therefore, option D is the correct answer.

The force of 301 N to the North can be broken into components of 301 N in the x-direction and 0 N in the y-direction.

The force of 280 N at 10.0° South of East can be broken into components of 250.5 N in the x-direction and -247.8 N in the y-direction.

The force of 313 N to the Southwest can be broken into components of -208.1 N in the x-direction and -278.9 N in the y-direction.

The net force is then the sum of the components in both the x- and y-directions.

The net force in the x-direction is 301 N + 250.5 N - 208.1 N = 343.4 N and the net force in the y-direction is 0 N - 247.8 N - 278.9 N = -526.7 N.

The net force is then the hypotenuse of a right triangle with the x- and y-components as the legs.

The net force is thus equal to √(343.4 N² + (-526.7 N)²) = 42.7 N.

Therefore, option D is the correct answer.

The surface area of the Triangular pyramid is approximately 331.3 square millimeters.

The surface area of a triangular pyramid, we need to calculate the area of its base and the area of each triangular face, then add them together. The formula for the surface area of a triangular pyramid is:

SA = (1/2)P*l + B

where SA is the surface area, P is the perimeter of the base, l is the slant height of each triangular face, and B is the area of the base.

In this case, the base of the triangular pyramid is an equilateral triangle with legs of 13 millimeters and a height of 11.3 millimeters. To find the area of the base, we can use the formula for the area of an equilateral triangle:

B = (sqrt(3)/4)*a^2

where a is the length of a side of the equilateral triangle.

Substituting a = 13 into the formula, we get:

B = (sqrt(3)/4)*13^2

B = (sqrt(3)/4)*169

B = 43.7 square millimeters (rounded to one decimal place)

Next, we can find the perimeter of the base:

P = 3a

P = 3*13

P = 39 millimeters

Now we can use the formula for the surface area of a triangular pyramid:

SA = (1/2)P*l + B

Substituting P = 39, l = 17, and B = 43.7, we get:

SA = (1/2)*39*17 + 43.7

SA = 331.3 square millimeters (rounded to one decimal place)

Therefore, the surface area of the triangular pyramid is approximately 331.3 square millimeters.

So the solution for h in terms of E, m, and g is h = E/mg.

As the graph of function f(x) is a parabola, so that the equation of function f(x) is:

f(x) = [tex]ax^2+bx+c[/tex]

As it can be seen in thee figure, the graph of function f(x) cross points (0;8) ;(-2; 0) and (4;0)

=> f(0) = 8; f(-2) = 0; f(4) = 0

We have:

f(x=0) = a x 0 + b x 0 + c = 8  => c = 8

We have:

+) 4a -2b + 8 = 0 => 2 x (4a -2b + 8) = 8a - 4b + 16 = 0 (1)

+) 16a + 4b + 8 = 0 (2)

We take (2) minus (1)

=> (16a + 4b + 8) - (8a - 4b + 16) = 0

=> 8a - 8 = 0 => a = 1

Replace a = 1 into (1)

=> 8 x 1 - 4b + 16 = 0 => b = 6

f (2) = 2^2 + 6 x 2 + 8 = 24

The speed of the plane in calm air is 372 km/h

Given that a plane is travelling from Winnipeg to Calgary against a 50 km/hr headwind.

This flight takes half an hour longer than it would in calm air.

The distance between Winnipeg and Calgary is 1200 km.

Since we know that,

Speed may be defined as the distance travelled by an item in relation to the time it takes to travel that distance.

In other words, it measures how rapidly an item travels but does not provide direction. The term "velocity" refers to the combination of direction and speed.

The speed is defined by the rate of distance.

We must determine the plane's speed in calm air.

xy=1200

(x-50)(y+1/2) =1200

x² - 50 x-12000=0

By using quadratic formula.

x=372 as x>0
