Answer:
Here's what I think I know:
1) the Voltage and the Resistance
2) Watts = Amps x Volts
so: 6 watts = A x 12, A = 0.5
Volts = Amps x Resistance
12 = 0.5 x R
R = 24 ohms
3) From step 2, A = 0.5 amps
4) since this is a series circuit, Re = Rh + 24

Julius’s walking rate is
(12 miles)/(3 hours) = (4 miles)/(1 hour)
time walked in 1 hour = 1 hour × (4 miles)/(1 hour) = 4 miles
time walked in 2.5 hours = 2.5 hours × (4 miles)/(1 hour) = 10 miles
time walked in 13 hours = 13 hours × (4 miles)/(1 hour) = 52 miles
time required to walk 27 miles = 27 miles × (1 hour)/(4 miles) = 6.75 hours
time required to walk 106 miles = 106 miles × (1 hour)/(4 miles) = 26.5 hours

Answers
Answer:
the area of above figure is 0.31 cm^2
Answer:
A ≈ 0.03 cm²
Step-by-step explanation:
Area of a circle = πr²,
where π (pi) ≈ 3.14 or 22/7 as a close fraction is the ratio (factor) between the circumference and the diameter (2 times / twice the radius),
and r² is the radius squared or multiplied by itself once.
Given that the radius is 0.1 cm in this situation,
the area of this circle is as follows:
A = πr² → A = π (0.1)² cm² → π(0.01) cm² → 0.01π cm² →
(1/100)(π) cm² → π / 100 cm² → 3.14 / 100 cm² →
0.0314 cm² ≈ 0.03 cm²

Two fifth grade classes are attending an amusement park as a field trip. Their teachers purchased the tickets for the class and the parent chaperones. Mrs. Lin purchased 3 child tickets and 17 adult tickets, which cost a total of $558. Mr. Shepherd purchased 3 child tickets and 11 adult tickets, paying a total of $378. What are the ticket prices?
Answers
Answer:
1 Adult ticket=$35
1 Children ticket=$20
Step-by-step explanation:
21C+15A=945
6C+6A=330
we find adult tickets 1st
42C+30A=1890
42C+42A=2310
12A=420
A=35
we will find children ticket next
42c+30a=1890
30c+30a=1650
12c=240
C=20
Consider the equation 1/4(x – 5) = (y – 2)^2. What is the equation of the directrix?
A.) x = 4.0000
B.) x = 4.7500
C.) x = 4.6250
D.) x = 4.9375
Answers
Answer:
D
Step-by-step explanation:
Find the vertex
¼(x-5) = (y-2)²
x-5 = 4(y-2)²
x = 4(y-2)² + 5
This is a right-opening parabola with vertex (5,2).
focal length p = 1/(4·coefficient of y²) = 0.0625
directrix: x = 5-p = 4.9375
D
The equation of directrix of the parabola will be x = 4, i.e. Option A.
What is directrix ?Directrix is a straight line distance to which from any point of a conic section is in fixed ratio to the distance from the same point to a focus. The directrix is perpendicular to the axis of symmetry and does not touch the parabola.
We have,
[tex]\frac{1}{4} (x - 5) = (y - 2)^2[/tex]
Now,
Rewrite as,
[tex](x - 5) = 4(y - 2)^2[/tex]
Now,
[tex]x= 4(y - 2)^2+5[/tex]
Now,
Comparing it with the vertex form,
i.e.
[tex]x = a ( y - h )^ 2 + k[/tex]
Vertex of parabola = (2, 5),
So,
Focus at (a, 0),
So,
Focus of the parabola = (4, 0),
i.e., a = 4
Now,
The Equation of directrix is given by x = a
So,
The equation of the directrix of this parabola,
x - a = 0,
i.e.
x - 4 = 0
⇒
x = 4
Hence, we can say that the equation of directrix of the parabola will be x = 4, i.e. Option A.
