Can someone help me . Thanks . Work is due tomorrow

Answer:

The value of cosA = (√3)/2 and tanA = 1/√3 or (√3)/3.

Step-by-step explanation:

Firstly,youhavetofindthevalueofadjacentusingPythogoras'Theorem,a²=b²+c²:

Let a = 2, b = 1

2² = 1² + c²

c² = 2² - 1²

= 4 - 1

= 3

c = √3

NowwehavefoundtheadjacentsowecanfindcosAandtanAusingTrigonometricfunction,cosθ=adj./hypo.andtanθ=oppo./adj.:

adj. = √3

oppo. = 1

hypo. 2

cosA = (√3)/2

tanA = 1/√3 OR (√3)/3

Answer:

The graph of the linear equation is attached below

Step-by-step explanation:

To graph a linear equation , we use a table method

We take some random number for x  and find out y. Always assume some positive as well as negative numbers.

x     y=3x-8

-1        3(-1)-8= -11

0        3(0)-8=-8

1         3(1)-8= -5

The points for graphing are (-1,-11)  (0,-8)  and (1,-5)

The graph of equation y = 3x - 8 is shown in image.

Since, The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

We have to given that;

Equation is,

⇒ y = 3x - 8

Now, By comparing with the equation of line, we get;

y - intercept of graph = (0, - 8)

And, Slope = 3

Hence, The graph of equation y = 3x - 8 with y - intercept is shown in image.

Answer: After 4 months they will have the same number of Stamps

Xian and Kai will have 124 stamps each one.

Step-by-step explanation:

60+16x = 76+12x (Subtract 12 from both sides)

-12 -12

60+4x = 76 (Subtract 60 from both sides)

-60 -60

4x/4x = 16/4x (Divide 16 by 4)

X = 4
