The solution is: the period for the graph of y = cos (0) is:

c.360

We have the following equation:

y = cos (0)

The first thing you should know is that the period of a function is that value for which the function repeats itself.

We have then:

y = cos (0) = 1

y = cos (360) = 1

Therefore, the period is 360.

The sides of the rectangle should be in improper fractions, to calculate the area.

When a side has a measurement that is a mixed number, it's recommended to convert it to an improper fraction before using it in the formula for area.

To convert a mixed number to an improper fraction, you multiply the whole number by the denominator of the fraction part and add the numerator.

Then, you put the result over the original denominator.

Once you have the sides of the rectangle as improper fractions, you can proceed to calculate the area using the formula: area = length x width.

Answer:

To calculate the length of BC in the triangle ABC, we can use the trigonometric functions sine and cosine.

Given that ∠CAB = 90° and ∠ABC = 58°, we can determine that ∠BCA = 180° - 90° - 58° = 32°.

Using the sine function, we can find the length of BC:

sin(∠BCA) = BC / AB

Rearranging the formula, we have:

BC = AB * sin(∠BCA)

Substituting the given values:

BC = 9.3 * sin(32°)

Using a calculator or trigonometric table, we find:

BC ≈ 9.3 * 0.529 = 4.917

Rounding to three significant figures (SF), the length of BC is approximately 4.92 units.

The requried, predicted percentage of U.S. households with an Internet subscription in 2020 is approximately 88.3%.

To find the number of subscriptions in the year 2020, we need to find the value of y when x = 10 (since x is the number of years after 2010).

Substituting x = 10 into the equation y = 1.56x + 72.7, we get:

y = 1.56(10) + 72.7

y = 15.6 + 72.7

y = 88.3

Answer:

r = 7

Step-by-step explanation:

equation of circle is (x - a)² + (y - b)² = r²

where a is x-coordinate of centre of circle, b is y-coordinate of centre of circle, r is the radius. radius = half of diameter.

x² - 8x + y² - 10y = 8

we need to complete the sqaure for both x and y

x² - 8x = (x - 4)² = x² - 8x + 16, which is 16 more than x² - 8x. so we need to subtract that 16.

we now have (x - 4)² - 16.

now do the same with y

(y - 5)² = y² - 10y + 25, which is 25 more than y² - 10y. so we need to subtract 25.

we now have (y - 5)² - 25.

back to our full equation.

(x - 4)² -16 + (y - 5)² - 25 = 8

(x - 4)² + (y - 5)² - 41 = 8

(x - 4)² + (y + 5)² = 49 = r²

radius r = √49 = 7

All points that lie on the line that passes through point `P` and is perpendicular to line ' t' are: (4, -1) and (6, -5)

The equation of a line in slope intercept form is:

y = mx + c

where:

m is slope

c is y-intercept

Using two coordinates on line t as: (-4, 1) and (2, 4), the slope of the line t is:

Slope = (4 - 1)/(2 + 4)

Slope = 3/6

Slope = 1/2

Equation of line t is:

(y - 1)/(x + 4) = 1/2

y - 1 = x/2 + 2

y = ¹/₂x + 3

Thus, slope of line passing through P and perpendicular to t is: -1/(1/2) = -2

Now, coordinates of point P is (3, 1). Thus:

Equation passing through point P and perpendicular to line t is:

(y - 1)/(x - 3) = -2

y - 1 = -2x + 6

y = -2x + 7

The only coordinates that fits into this are (4, -1) and (6, -5)

Answer:

12) x = 6. 13) not tangent

Step-by-step explanation:

12) x² - 5 = 31 (since they are both tangents)

x²  = 31 + 5 = 36

x = ±6

x = +6 (has to be positive since it's a length).

13) if it was tangent, angle BAC would be 90°.

that would also mean AB²  = BC² - AC²

                                            =  15² - 5²

                                            = 225 - 25

                                           = 200

AB = √200 ≠ 14.

Since the values are different, AB is not a tangent to the circle

To solve the equation 3x/4 = 7/3, you can follow these algebraic steps:

Step 1 :
Multiply both sides of the equation by 4 to eliminate the fraction in the denominator of the left side:

3x = 28/3

Step 3 :
Divide both sides of the equation by 3 to isolate x:

(1/3) (3x) = (1/3)(28/3)

x = (28/3) / 3

The volume of a rectangular prism, with dimensions length, width and height, is given by the multiplication of these dimensions, according to the equation presented as follows:

Volume = length x width x height.

The dimensions for this problem are given as follows:

45 cm, 50 cm and 38 cm.

Hence the volume of the tank is given as follows:

V = 45 x 50 x 38

V = 85,500 cm³.

Three-fifths of the volume is given as follows:

3 x 85500/5 = 51300 cm³.

The height associated with 3/5 of the volume is given as follows:

50 x 38 x h = 51300

h = 51300/(50 x 38)

h = 27 cm.

This means that 27 - 13 = 14 cm flew into the tank in 25 minutes, hence the minute rate is given as follows:
