Answers
Answer:
[tex]\Huge \boxed{\mathrm{B. \ 6}}[/tex]
Step-by-step explanation:
We can apply the Intersecting Secant-Tangent Theorem.
TV is the secant.
VW is the tangent.
VW² = VT × VU
(x+6)² = (5+x+4) × (x+4)
Combine the terms in bracket.
(x+6)² = (x+9)(x+4)
Expand brackets on both sides of the equation.
x²+12x+36=x²+13x+36
Subtract x² from both sides.
12x+36=13x+36
Subtract 12x from both sides.
36=x+36
Subtract 36 from both sides.
0=x
WV = x+6
x=0
WV = 0+6 = 6
The measure of the tangent WV is 6.

Two objects were lifted by a machine. One object had a mass of 2000 grams, and was lifted at a speed of
2 m/sec. The other had a mass of 4000 grams and was lifted at a rate of 3 m/sec.
a. Which object had more kinetic energy while it was being lifted?
Answers
Answer:
The second object (4000 grams) had more kinetic energy
Step-by-step explanation:
Use the equation KE = 0.5mv², where m is the mass and v is the velocity.
Find the kinetic energy of the first object:
KE = 0.5(2000)(2 m/s)²
KE = 4000 J
Find the kinetic energy of the second object:
KE = 0.5(4000)(3 m/s)²
KE = 18000 J
So, the second object (4000 grams) had more kinetic energy.
The second object of mass 4000 grams will have more kinetic energy than the first mass.
What is kinetic energy?The energy that an object has as a result of motion is known as kinetic energy. It is described as the effort required to move a mass-determined body from rest to the indicated velocity.
Use the equation KE = 0.5mv², where m is the mass and v is the velocity.
The kinetic energy of the first object:
KE = 0.5(2000)(2 m/s)²
KE = 4000 J
The kinetic energy of the second object:
KE = 0.5(4000)(3 m/s)²
KE = 18000 J
Therefore, the second object (4000 grams) had more kinetic energy.

Step-by-step explanation:
Given that :
Kim was waling down a path for 4 minutes the elavation changed at the same rate altogether it dropped 8 feet what was the change in elavation each minute?
Time taken it wall down the path = 4 minutes
Rate of change of elevation is the same

Distance dropped / time taken to drop that distance
8 Feets / 4 minutes
2 Feets / minute
Change in elevation = 2 Feets per minute
Aluminum is a highly reactive metal that oxidizes when exposed to air. Which of these would be a good first step in balancing this reaction? Al + O2 → Al2O3
Answers
Answer:
first step to balance the equation is :

balanced equation : 4 Al +3O2 → 2 ALO3
Step-by-step explanation:
Al + O2 → Al2O3
first step to balance the equation is :
multiply AL by 2 to match the amount of aluminum on the other side
but then you have to deal with the amount of O from both sides, we need to find the least common multiple between 2 and 3 which is 6
the best thing to balance the equation is to multiply O2 by 3 and O3 by2, then deal with the amount of AL which is 4 on the other side. last step is to multiply AL by 4 to balance the equation.

Sarah and Jim leave a train station at the same time traveling 20mi/h faster that Jim’s train. After 3 hours the were 270 miles apart how fast was each train going
Answers
Answer:
speed of Jim's train = 35 mi/h
speed of Sarah's train = 35 +20 mi/h = 55 mi/hour
Step-by-step explanation:
Let the speed of Jim's train be x mi/h
Given, Sarah and Jim leave a train station at the same time traveling 20mi/h faster that Jim’s train.
speed of Sarah's train = x + 20 mi/h
we know distance = speed * time
time = 3 hours
distance traveled by Sarah's train = 3*(x+20) = 3x+60 miles
distance traveled by Jim's train = 3*x = 3x miles
It is not given that if trains are moving in same or opposite direction.
__________________________________
if they are travelling in same direction
Then, then distance between them = total distance traveled by
faster train - total distance traveled by
slower train = 3x +60 -3x = 60 miles
which is wrong as the two trains are 270 miles apart
hence, they are travelling in opposite direction
In this case
distance between them = total distance traveled by
faster train + total distance traveled by
slower train = 3x +60 + 3x = 6x + 60 miles
given that the trains are 270 miles apart
6x + 60 miles = 270 miles
6x = 270 - 60 = 210
x = 210/6 = 35
Thus, speed of Jim's train = 35 mi/h
speed of Sarah's train = 35 +20 mi/h = 55 mi/hour

The entire graph of the function f is shown in the figure below. Write the domain and range of f using interval notation?
Answers
========================================================
Explanation:
The domain is the set of allowed x values. In terms of a graph, we look at the left most point to see that x = -5 is the smallest x value possible. However, there's an open hole at this endpoint, so -5 itself is actually not part of the domain. So x must be larger than -5. At the same time, x can be as large as x = 3. Look at the very right tip of the graph to find this x value.
So x spans from -5 to 3, excluding -5 but including 3. We would write [tex]-5 < x \le 3[/tex] which converts to the interval notation (-5, 3]. Note the mix of curved parenthesis and square bracket. The curved parenthesis means to exclude the endpoint, while the square bracket means include the endpoint.
-----------
The range is the set of possible y outputs. Find out the lowest point of the graph. That is when y = -4 and this value is included due to the filled in circle at the endpoint. But we do not include the largest y value y = 5 as there's an open hole at this endpoint.
So the range is the set of y values such that [tex]-4 \le y < 5[/tex] which in interval notation would be written as [-4, 5)
-----------
So in short, you're looking for the min and max of x and y to get the domain and range respectively. Be sure to exclude any values where there are open holes as those do not count as part of the graph.
For a given function f(x), we define the domain as the set of the possible inputs for that function.
Here we will see that the domain is (-5, 3]
So, to find the domain by looking at a graph, we need to see the smallest x-value and the largest x-value.
In the graph, at the left, we can see that we have a white dot at x = -5
This means that the point itself does not belong to the domain, so here we need to use an open interval symbol, which is (
Then at the moment, we have:
domain = (-5
Now if we look at the right side, we can see that we have a black dot at x = 3.
This means that the value x = 3 belongs to the domain, so here we need to use the close symbol ].
Then the domain will be:
(-5, 3]

2% Of A=3% OF B = 4% of c then A:B:C: is?
Answers
Answer:
6:4:3.....................
The ratio between A, B, and C is 6:4:3.
To determine the ratio between A, B, and C based on the given information, we can set up the following equations:
2% of A = 3% of B
4% of C = 3% of B
Let's solve for the variables and find the ratio:
First equation: 2% of A = 3% of B
0.02A = 0.03B
A/B = 0.03/0.02
A/B = 1.5
Second equation: 4% of C = 3% of B
0.04C = 0.03B
C/B = 0.03/0.04
C/B = 0.75
Now, let's express the ratio A:B:C based on the ratios we found:
A:B = 1.5:1
B:C = 1:0.75
To obtain a common ratio, we can multiply both ratios by 4:
A:B = 6:4
B:C = 4:3
Combining these ratios, we have:
A:B:C = 6:4:3
Therefore, the ratio between A, B, and C is 6:4:3.

Given
Gopal gives Rs 10 from his money to Laxmi her money becomes double thanthat of the remaining money of Gopal
Money left with gopal after giving Rs 10 = x-10
money with Laxmi after getting rs 10 = y+10
according to given condition
money with laxmi = 2*money left with Gopal
y+10 = 2(x-10)
___________________________________________________
Laxmi gives Rs 10 to Gopal his moneyis still Rs 10 less than the remaining money of Laxmi.
Money left with Laxmi after giving Rs 10 = y-10
money with Gopal after getting rs 10 = x+10
according to given condition
money with laxmi -10 =money with Gopal
y-10-10 =x+10
y-20 = x+10
=> y = x+10+20
y = x+30
substituting y = x+30 in y+10 = 2(x-10)
x+30 +10 = 2(x-10)
x+40 = 2x-20
=>40+20 = 2x-x
=> x = 60
y = x+30 = 60+30 = 90

Find the measure of b. A. 126 B. 31.5 C. 27 D. 63
Answers
Answer:
D. 63°
Step-by-step explanation:
a = 27°
b = 180° - (a + 27°)
b = 180° - (27° + 27°)
b = 180° - 54°
b = 126°
By inscribed angle theorem:
c = 1/2 b = 1/2 * 126°
c = 63°
The measure of angles a, b, and c in the given figure are 27°, 126°, and 63°, respectively.
What is an isosceles triangle?An isosceles triangle is one with two equal-length sides. It is sometimes stated as having exactly two equal-length sides, and sometimes as having at least two equal-length sides, with the latter form containing the equilateral triangle as a particular case.
In the triangle ORQ, the two sides of the triangle OR and OQ are the radius of the triangle, therefore, the length of the two sides will be.
Since the two sides of the triangle are equal, therefore, the triangle will be an isosceles triangle, with the angle opposite to the same length measuring the same. Therefore,
∠OQR = ∠ORQ
a = 27°
Now, in a triangle, the sum of the measure of all the angles is equal to 180°. Therefore, we can write,
∠OQR + ∠ORQ + ∠QOR = 180°
a + 27° + b = 180°
27° + 27° + b = 180°
b = 180° - 27° - 27°
b = 126°
Further, In a circle, the measure of the angle formed by the chord in the centre of the circle is twice the measure of the angle formed by the same chord on any point in the circle. Therefore,
∠QOR = 2∠QPR
b = 2 × ∠QPR
126° = 2 × ∠QPR
∠QPR = 126° / 2
∠QPR = 63°
Hence, the measure of angles a, b, and c in the triangle are 27°, 126°, and 63°, respectively.
