Answer:
between 7 and 8
Step-by-step explanation:
7 squared is 49
8 squared is 64
49 < 52 < 64
1) Speed is measured in distance units divided by time units, such as miles per hour. Here, you're given the number of miles traveled and the number of hours it takes, so you can figure tha average speed to be
... speed (or "rate of change") = distance/time = 165 mi/(3 h) = 55 mi/h
2) "speed at the moment" 1.5 hours into the flight means ...
... d. an instantaneous rate of change at 1.5
3) To keep their average speed on target, the dragons must travel at higher than their average speed for a while.
Answer:
42°, 101°
Step-by-step explanation:
These answers come from the angle subtraction postulate.
To answer the item, we let x be the number of 2-point baskets and y be the 3-point basket, respectively. The system of linear equations that would allow us to express the given mathematically is,
x + y = 37
2x + 3y = 80
To determine the values of the variables, express x of the first equation in terms of y.
x = 37 - y
Substituting this to the second equation,
2(37 - y) + 3y = 80
The value of y from the equation is 6.
x = 37 - 6 = 31
<em>Answer: 31 two-point baskets</em>
Answer:
y=(-5/3)x+29
Step-by-step explanation:
we will use the base formula y=mx+b
In order to be perpendicular, the slope must be the flipped fraction and have the opposite sign, so our m is (-5/3)
y=(-5/3)x+b
You can plug in the (9,14) point in order to find the b
14=(-5/3)(9)+b
14=(-45/3)+b
14=(-15)+b
14+15=b
29=b
and so altogether our equation is y=(-5/3)x+29
