Answer:
Step-by-step explanation:
1a) the y intercept, or 20
b) from 0 weeks to 1 week the difference is 10
c) its y=mx+b m is the slope(difference) and b is the y-int so y = 10x+20
2a) the y int, is the same as the x(number of games played) being zero, so here it is 25
2b) after 3 games it was a loss of 1.50 !!! IMPORTANT !! after THREE weeks, so its 1.5/3=0.5 amount on card per week
2c) (ref 1c) but with that same formula/equation - we get y=0.5x+25
Answer:
(-2.5, 0.5)
Step-by-step explanation:
(-4) + (-1) / 2 = -2.5
5 + (-4) / 2 = 0.5
Answer:
The rate of change is 1/2 and the y-intercept is 1
Step-by-step explanation:
You can calulate the rate of change by picking two points on the graph and using the slope formula
(y2-y1)/(x2-x1)
so in this example you can use the points (2,2) represeting (x1,y1) and (4,3) representing (x2,y2)
When you plug into the slope formula you get:
(3-2)/(4-2) = 1/2 which is the slope.
The y-intercept is where the line intersects the y=axis and can be seen as the coordinate pair (0, #) where the # is the y intercept. From the graph you can see the y-intercept is 1, but you can aslo solve for the y-intercept using the slope-intercept equation:
y=mx+b
where b is the y-intercept and m is the slope.
so using a slope of 1/2 and a coordinate of (2,2) you get:
y-2=(1/2)(x-2)
y = (1/2x)-1+2
y = (1/2x) + 1
so now the equation is in slope-intecept form and you can see the slope is 1/2 and the y-intercept is 1
Answer:
B)313 ft
Step-by-step explanation:
Hello,I think I can help you with this
to solve this you need to find all the measures of the rigth triangle formed by Hailey, the boat, and the point on the surface of the sea just above the head of Hailey
Step 1
define
triangle
Hypotenuse=300 feet
opposite side=y
adjacent side=x
angle of depression =30°
Step 2
find the distances
so, the point on the surface of the sea just above hailey is 259.8076 ft from the boat
hailey is at a depth of 150 feet
Step 3
now,her partner is 25 feet directly below her,it is
partner's depth is =hailey is at a depth of 150 feet+25
Y=175
he is at the same distance from de boat ( horizontal),because it is the same point in the sea surface.
X=259.80
Step 4
to find the distance between the partner and the boat we can use
Pythagoras theorem
so, Hailey's diving partner is 313 ft away from the boat(B)
Have a great day.
