∴ ∠ABC= ∠ABE+∠EBC
= 74°+64°

work out the equation of the line which has a gradient of 2 and passes through the point (1,4).
Answers
Answer:
y = 2x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (1, 4) into the partial equation
4 = 2 + c ⇒ c = 4 - 2 = 2
y = 2x + 2 ← equation of line
Answer: y=2x+2

Exercise 41
To measure the width of a river, you plant a stake on one side of the river, directly across from a boulder.
You then walk 100 meters to the right of the stake and measure a 79° angle between the stake and the
boulder. What is the width w of the river? Round your answer to the nearest meter.

Answers
Answer:
514 m = width of the river to the nearest meter
Step-by-step explanation:
You must memorize the definitions of the trig functions and then these types of problems are easy.
You have a right triangle where the 100 m is the adjacent side to the 79° angle. You are looking for the side opposite the 79° angle. So, you need to use the tan function which is defined as opposite side/adjacent side
Let x = the length of the opposite side (width of river)
Tan 79 = x/100
100 tan 79 = x
x = 514 m = width of the river to the nearest meter
The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The width of the river is 514.455 meters.
What is Tangent (Tanθ)?The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]
where,
θ is the angle,
Perpendicular is the side of the triangle opposite to the angle θ,
Base is the adjacent smaller side of the angle θ.
As it is given that you walk 100 meters to the right of the stake and measure a 79° angle between the stake and the boulder. Therefore, using the tangent angle the width of the river can be written as,
[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\\\\\\\rm tan(79^o) = \dfrac{\text{Width of the river}}{100\ meter}\\\\\\\text{Width of the river} = tan(79^o) \times 100 = 514.455\ meters[/tex]
Hence, the width of the river is 514.455 meters.

You can slit it into two rectangles. On rectangle would have a area of 2x6 and another rectangle could have an area of 6x3. then you solve the area of the rectangles and add them for the total area. I have a picture of it:
Answer:
30 square feet
Step-by-step explanation:
1. Approach
Break up the given figure into two smaller rectangles. Calculate the area of those two rectangles, and then add up the results.
2. Rectangle 1
The is one extend the line with the measurement of (4ft), then one will get a rectangle with the dimensions of (6ft) and (3ft). Use the formula,
[tex]length * height = area[/tex]
Substitute;
6 * 3 = 18
3. Rectangle 2
The other rectangle that will result from this partitioning will have the dimensions (2ft) and (6ft). Again use the formula,
[tex]length * height = area[/tex]
Substitute,
2 * 6 = 12
3. Find the total area
Add up the area of these two smaller rectangles,
rectangle1 + rectangle2
= 18 + 12
= 30

A raffle has 50 tickets. One ticket will win a $590 prize. The rest will win nothing. If you have a ticket, what is the expected payoff?
Answers
Answer:
$11.8
Step-by-step explanation:
Probability of winning = 1/50
Probability of not winning = 1 - 1/50 = 49 / 50
Amount won = 590
X : ____ 590 ___ 0
P(X) : __ 1/50 __ 49/50
Expected payoff :
ΣX * p(x)
(590 * 1/50) + (0 * 49/50)
0.02 * 590 + 0
11.8 + 0
= $11.8
