Answer:
13 cms
Step-by-step explanation:
By Pythagoras:-
x^2 = 12^2 + 5^2
x^2 = 144 + 25
x^2 = 169
x = √169
= 13
Answer: D) The graph of y = f(x) will shift down 13 units.
Step-by-step explanation:
Let's define the transformations of translations.
If we start with a function f(x):
For A > 0.
An horizontal translation of A units to the right is written as g(x) = f(x - A)
An horizontal translation of A units to the right is written as g(x) = f(x + A).
A vertical translation of A units up is written as g(x) = f(x) + A
A vertical translation of A units down is written as g(x) = f(x) - A.
In this question we have the transformation:
y = f(x) - 13
This is a translation of 13 units down, then the correct option is:
D) The graph of y = f(x) will shift down 13 units.
Answer:
The top speed of William's boat was 45 mph
Step-by-step explanation:
Let
x -----> represent the rate of the boat in still water in mph
we know that
The speed or rate is equal to divide the distance by the time
speed=distance /time
time=distance/speed
<em>Downstream</em>
speed=(30+x) mph
distance=10 mi
time1=10/(30+x)
<em>Upstream</em>
speed=(x-30) mph
distance=2 mi
time2=2/(x-30)
The sum of the time downstream plus the time upstream must be equal to 16 minutes
Convert minutes to hours
Multiply by (x+30)(x-30) both sides
Multiply by 60 both sides
Divide by 16 both sides
The solution is x=45\ mph
Answer:
111 cars
Step-by-step explanation:
30% of 78 is
78×30%=78×0.3=23.4
Cars needed to sell
78+23.4=111.4
Unless we can't have 0.4 of a car, we need to round that number, so 111.4≈111
