Answer:

see explanation

Step-by-step explanation:

Using identities

sec²x = tan²x + 1

cosec²x = cot²x + 1

cos²x = [tex]\frac{1}{cos^2x}[/tex]

(1)

sin²θ + [tex]\frac{1}{sec^20}[/tex]

= sin²θ + cos²θ = 1

(2)

9sec²θ - 9tan²θ

= 9sec²θ - 9(sec²θ - 1)

= 9sec²θ - 9sec²θ + 9

= 9

(3)

- 8cot²A + 8cosec²A

= - 8cot²A + 8(cot²A + 1)

= - 8cot²A + 8cot²A + 8

= 8

(4)

- 10cosec²β + 10cot²β

= - 10(cot²β + 1) + 10cot²β

= - 10cot²β - 10 + 10cot²β

= - 10

Answer:

Unit digit of this number is 0, hence divisible by 10. Hence, 19400 is divisible by 2, 5 and 10. This is an even number, hence divisible by 2. Unit digit of this number is 0, hence divisible by 5.

46 yards was travelled north while 172 yards was travelled west.

Trigonometric ratios shows the relationship between the sides of a triangle and its angles.

For the question, the distance travelled north and distance travelled west can be determined using trigonometric ratio.

sin(15) = distance travelled north / 178

Distance travelled north = 46 yards

Also:

cos(15) = distance travelled west / 178

Distance travelled west = 172 yards

Hence, 46 yards was travelled north while 172 yards was travelled west.

Answer:

y=5x+5

Step-by-step explanation:

Answer:

Y=5x-5

Step-by-step explanation:

-3y=-15x+15

3y=15x-15

Y=5x-5

first, make the line into slope-intercept form.

-3x - 5y = 1

-5y = 3x + 1

y = -3/5x - 1/5

a line parallell to this line has to have the same slope, so it could be but doesn't have to be y = -3/5x - 1

a line perpendicular to y = -3/5x - 1/5 has to have the opposite slope of it.

so, y = 5/3x +1

Hello!

y=-1/3x+6

Perpendicular lines have slopes that are opposite reciprocals.

This means that if we have a slope of -1/3, its opposite reciprocal would be 3

Use Point-Slope form:

y-y1=m(x-x1)

y-4=3(x-2)

y-4=3x-6

y=3x-6+4

y=3x-2

Step-by-step explanation:

Step-by-step explanation:

just think a little bit.

congruent rectangles means they are all of equal size.

so, the sizes of all of these rectangles are 3×4.

therefore, the area of each one is 3×4 = 12 cm².

the total surface area (without the top

and bottom stars) is the sum of the areas of all rectangles.

how many rectangles are there ?

well, every "arm" of the star has 2 rectangle sides. and there are 5 "arms". so, there are 2×5 = 10 rectangles.

now it is really easy, right ?

we have 10 rectangles, each one with an area of 12 cm².

so the total surface area (without the star bases) is

12×10 = 120 cm²

Answer:

11

Step-by-step explanation:

Answer:

f(-2) = 11

Step-by-step explanation:

Given the function, f(x) = -3x + 5:

We can evaluate f(-2) by substituting -2 as the input (or x-value) for the function:

f(-2) = -3x + 5

f(-2) = -3(-2) + 5

f(-2) = 6 + 5

f(-2) = 11

Therefore, f(-2) = 11.
