If a 50 kg object is at a location 25,600 km from Earth’s center, what is the gravitational force exerted by the object on Earth? In what direction does that force act?
Answer:
Approximately [tex]30\; \rm N[/tex] toward the center of the object.
Step-by-step explanation:
Look up the gravitational constant and the mass of the earth:
[tex]\begin{aligned}G &\approx 6.67 \times 10^{-11}\; \rm m^{3} \cdot kg^{-1} \cdot s^{-2} \\ &= 6.67 \times 10^{-11} \; \rm N \cdot m^{2} \cdot kg^{-2}\end{aligned}[/tex].
[tex]M \approx 5.97 \times 10^{24}\; \rm kg[/tex].
Convert the unit of distance to standard units:
[tex]\begin{aligned}r &= 25600\; \rm km \\ &= (25600 \times 10^{3})\; \rm m \\ &= 2.56 \times 10^{7}\; \rm m\end{aligned}[/tex].
Consider two spherical objects with mass [tex]m_{1}[/tex] and [tex]m_{2}[/tex]. Let [tex]r[/tex] denote the distance between the centers of the two objects. By Newton's Law of Universal Gravitation, the size of the gravitational force between these two objects would be:
[tex]\begin{aligned}F &= \frac{G \cdot m_{1} \cdot m_{2}}{r^{2}}\end{aligned}[/tex].
Thus, the size of the gravitational force between this object and the earth would be:
[tex]\begin{aligned}F &= \frac{G \cdot m \cdot M}{r^{2}} \\ &\approx \frac{1}{2.56\times 10^{7}\; \rm m} \\ &\quad \times 6.67 \times 10^{-11}\; \rm N \cdot m^{2}\cdot kg^{-2} \\ &\quad \times 50\; \rm kg \times 5.97 \times 10^{24}\; \rm kg \\ &\approx 30\; \rm N\end{aligned}[/tex].
Since gravitational force is attractive, the [tex]50\; \rm kg[/tex] object in this question would attract the earth through the gravitational force. Thus, this force would point towards the center of this [tex]50\; \rm kg\![/tex] object.
Let f(x)=x^2+4
Write a function g whose graph is a reflection in the y-axis of the graph of f.
Answer:
[tex]g(x)=x^2+4[/tex]
Step-by-step explanation:
Hi there!
Given:
[tex]f(x)=x^2+4[/tex]
Let g be a function whose graph is a reflection in the y-axis of the graph of f.
What we need to know:
To reflect a function f in the y-axis, we would need to multiply x by -1:
[tex]g(x)=f(-x)[/tex]
Apply and solve:
[tex]g(x)=(-x)^2+4\\g(x)=x^2+4[/tex]

If Ann is traveling at 120 km/hr, what
distance does she travel in 10 minutes?
Answer:
20 km
Step-by-step explanation:
120 km an hour = 120 km in 60 minutes
120 = 60
x = 10
120/60 = 2
10*2 = 20
Answer:
20 km.
Step-by-step explanation:
120 km per hour.
An hour is 60 minutes.
To get from 60 to 10, divide 6.
Likewise, to find the distance travelled in 10 minutes, divide 120 by 6.
[tex]\frac{120}{6}= 20[/tex]
Therefore, Ann travels 20 km in 10 minutes.

To get the 10% discount, a shopper must spend more than $500.
Use d to represent the spending (in dollars) of a shopper who gets the discount
Answer:
d[tex]\geq[/tex]$500
Step-by-step explanation:
To get the 10% discount, a shopper must spend at least $500
so 'd' represents the spending (in dollars) of a shopper who gets the discount
The value of d must be greater than or equal to $500
d[tex]\geq[/tex]$500

9. Rashida bought 4 tickets to a concert for $80. At this rate, how much would 5 tickets cost?
Number of Tickets
4.
5
Money Spent (5)
80
Answer:
$100
Step-by-step explanation:
4 tickets cost $80.
We divide $80 by 4 to find the cost of 1 ticket.
$80/4 = $20
1 ticket costs $20.
Now we multiply $20 by 5 to find the cost of 5 tickets.
5 * $20 = $100
Answer: $100
Solve the following question:
Answer:
x = 2, x = 8
Step-by-step explanation:
reminder that f'(x) = [tex]m_{tangent}[/tex]
Differentiate f(x) term by term using the power rule
[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex]
f(x) = [tex]\frac{1}{3}[/tex] x³ - 5x² + 2x + 10
f'(x) = x² - 10x + 2
Equating f'(x) to - 14
x² - 10x + 2 = - 14 ( add 14 to both sides )
x² - 10x + 16 = 0 ← in standard form
(x - 2)(x - 8) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
x - 8 = 0 ⇒ x = 8
