Answer:
- <u>See the picture attached with the drawing of the forces.</u>
Explanation:
Find the figures with the question and the answer attached.
The answer shows the free body diagram with four arrows starting on, and pointing way from, the dot.
The red vertical upward arrow, labeled 
, represents the normal force, which is the force exerted by the ground on the cart.
The red vertical downward arrow, labeled 
, represents the gravity force (weight), which is the pull that the Earth exerts of the cart.
Both vertical arrows are of the same side because the normal force and the weight are balanced (since there is not vertical acceleration).
The blue horizontal arrow pointing to the right, labeled 
, represents the horizontal pulling force exerted by the hand.
The blue horizontal arrow pointing to the left, labeled 
, represents the frictional force which is not neglicible.
Since the cart is accelerating in the positive direction, toward the right,
and the arrow to the right is larger than the arrow to the left.
Answer:
f(x)= 50+4.25x
g(x)= 40+6.25x
(5, 71.25)
Explanation:
they are asking for the number of garmets and price of those garmets where both shops charge the same amount
if you make the two shops prices into equations you will be trying to find the line intercept
to make the lines equations
they said f(x) is cleaning company 1
g(x) is cleaning company 2
and x in the number of garmets cleaned
you can see from prices that the price does not start at 0 it has a baseline price to clean
that baseline price is the +____
113.75-92.50 to find the difference in price for 5 garmets
=21.25
21.25/5 to find raise in price per 1 garmet
=4.25
now we know its 4.25x+b
baseline price = b
to find b plug in the values on the chart (first row)
4.25(5)+b=71.25
21.25+b=71.25
b=50
baseline price = 50
store 1 price is= f(x)= 50+4.25x
im gonna run out of space ill do the second one short
103.75-72.5=31.25
31.25/5=6.25
71.25=6.25(5)+x
71.25-31.25=x
x= 40= base price
g(x)= 40+6.25x
find intersection
g(x) =y
f(x) = y
y=y
therefore
50+4.25x=40+6.25x
10+4.25x=6.25x
10+4.25x=6.25x
10=2x
x=5
to find y intersection put in x to equation
y= 50+4.25x
y= 50+4.25(5)
y=50+21.25
y=71.25
intersection is (5, 71.25)
Answer:
Scientists think that foxgloves have evolved the poisons as an evolutionary adaptation and defense mechanism that provided them with better survival capacities.
As poisons are repellents which help the plants to repel any predator or attacker and enhance their survival. That is why scientists are of the view that old fox glove did not necessarily had this poison many hundred years ago but some how there would be facing harsh circumstances or alot of predators. Due to which, with the passage of time they developed these chemicals which enhanced their life time and survival chances.
Some poisonous chemicals from foxglove are:
- Deslanoside
- Digitoxin
- Digitalis glycoside
Hope it help!
