Answers

Answer:

g(x) has an axis of symmetry at x = 3.

g(x) is shifted right 3 units from the graph of f(x)

g(x) is shifted up 4 units from the graph of f(x).

Step-by-step explanation:

The parent function is:

[tex]f(x)=x^2[/tex]

The transformed function is [tex]g(x)=-x^2+6x-5[/tex].

This new function can be rewritten in the vertex form as:

[tex]g(x)=-(x-3)^2+4[/tex]

This function is obtained by shifting the parent function 3 units right and 4 units up.

The axis of symmetry is x=3;(x=h) and h=3.

The current flowing through an electric circuit is the derivative of the charge as a function of time. If the charge q is given by the equation q(t)=3t^2+2t-5 what is the current at t = 0?

Answers

Answer:

The current at t = 0 is

[tex]I (0) = 2[/tex] units of current

Step-by-step explanation:

If the current flowing through an electric circuit is defined as the derivative of the charge as a function of time and we have the equation of the charge as a function of time, then, to find the equation of the current, we derive the equation of the charge.

[tex]q (t) = 3t ^ 2 + 2t-5[/tex]

[tex]\frac{dq(t)}{dt} = 3 (2) t ^ {2-1} +2t ^ {1-1} -0[/tex]

Simplifying the expression we have:

[tex]\frac{dq(t)}{dt} = 6t + 2t ^0\\\\\frac{dq(t)}{dt} = 6t + 2 = I (t)[/tex]

Finally, the equation that defines the current of this circuit as a function of time is:

[tex]I (t) = 6t +2[/tex]

Now to find the current at t = 0 we make [tex]I (t = 0)[/tex]

[tex]I (0) = 6 * 0 +2[/tex]

[tex]I (0) = 2[/tex] units of current

Which criteria for triangle congruence can be used to prove the pair of triangles below are congruent?

A. SAS
B. ASA
C. AAS
D. none

Answers

Answer:

A)SAS

Step-by-step explanation:

The tick marks represent which sides of the triangles are congruent, while the arc represents which angles are congruent.

Since the arc is in between the sides that are congruent therefore the postulate is Side Angle Side

Final answer:

Without visual or informational context, the congruence criteria between the pairs of triangles cannot be determined. It's essential to know specific details about the triangles to apply congruence criteria like Side-Angle-Side (SAS), Angle-Side-Angle (ASA), or Angle-Angle-Side (AAS). However, with no further details, the answer is 'D. None'.

Explanation:

To determine which criterion for triangle congruence can be used to prove that the pair of triangles are equal, we first need to examine the triangles. SAS refers to Side-Angle-Side, which is when two sides and the included angle of one triangle is congruent to two sides and the included angle of another triangle. ASA refers to Angle-Side-Angle, which is when two angles and the included side of one triangle is congruent to two angles and the included side of another triangle. AAS refers to Angle-Angle-Side, which is when two angles and a non-included side of one triangle is congruent to two angles and a non-included side of another triangle. So, without a visual or further information about the triangles, we cannot directly apply any particular congruence criteria and the answer would be 'D. none'. However, with more information, the pair of triangles can possibly be proven congruent using either SAS, ASA, or AAS methods.

An object is launched into the air. The projectile motion of the object can be modeled using the function h(t) = –16t2 + 72t + 5, where t is the time in seconds since the launch and h(t) represents the height in feet of the object after t seconds. What is true about the projectile motion of this object? Check all that apply. The initial height is 5 feet. The initial velocity of the object is –72 feet/second. The object will hit the ground after approximately 4.57 seconds. After 3 seconds, the object is 173 feet high. At t = 0, h(t) = 0.

Answers

Answer:

Step-by-step explanation:

In the equation, 72t represents the initial upwards velocity and 5 represents the initial launching height.  The leading term represents the pull of gravity on the object in the English system of measurement.

So the first question says the initial height is 5 feet.  TRUE

The second question says the initial vertical velocity is -72.  FALSE (it's positive 72 ft/sec)

The third question says that the object will hit the ground after approximately 4.57 seconds.  TRUE.  Find this by setting the h(t) on the left equal to 0, since this is the height at any time during the flight.  When h(t) = 0, that means that there is NO height, which means the object is on the ground.  Set the equation equal to 0 and factor to find t.  Putting that into the quadratic formula gives you t values of -.068 and 4.57.  Since the 2 things in math that will NEVER EVER be negative are distances and time, we can safely disregard the negative t value and go with t = 4.57.

The fourth question says that after t = 3 seconds, the object is 173 feet high.  FALSE.  Find this by subbing in a 3 for every t in the equation.

[tex]h(3)=-16(3)^2+72(3)+5[/tex]

This gives you that h(3) = 77 feet

The last question says that at t = 0, h(t) = 0.  FALSE again.  Sub in a 0 for every t in the equation, and you get h(0) = 5, which is the initial launching height.

Answer:

The initial height is 5 feet.

The object will hit the ground after approximately 4.57 seconds.

A & C

Step-by-step explanation

An object is launched into the air. The projectile motion of the object can be modeled using the function h(t) = -16t^2 + 72t + 5, where t is the time in seconds since the launch and h(t) represents the height in feet of the object after t seconds

General equation is

V_0 is the initial velocity

h_0 is the initial height

From the given equation , the initial height is 5 feet

Initial velocity is +72 feet / sec

When the onbject hits the ground, the height becomes 0

So we plug in 0 for h(t) and solve for t

USe quadratic formula to solve for t

a=-16, b= 72, c= 5

t= -0.06  and t= 4.568

The object will hit the ground after approximately 4.57 seconds.

To find out the height after 3 seconds, plug in 3 for t

At t=0 , h(0) = 5

If the ratio between the radii of the two sphere is 3:5, what is the ratio of their volumes?

A. 3:25
B. 6:25
C. 9:25
D. 27:125

Answers

Answer: Option D

Step-by-step explanation:

You know that the ratio between the radii of the two sphere is 3:5. Knowing this fact, you can calculate the ratio of their volume with this procedure:

[tex]ratio\ volume=\frac{3^3}{5^3}[/tex]

You need to remember that:

[tex]a^3=a*a*a[/tex]

 Then, you can rewrite it as:

[tex]ratio\ volume=\frac{3*3*3}{5*5*5}[/tex]

Finally, you get the the ratio of the volumes of the spheres is:

[tex]ratio\ volume=\frac{27}{125}[/tex] or 27:125

This matches with the option D.

Answer:

The ratio of their volumes is 27 : 125

Step-by-step explanation:

Points to remember

Volume of sphere V = 4/3(πr³)

Where r is the radius of sphere

To find the ratio of volume of spheres

It is given that,  the ratio between the radii of the two sphere is 3:5

V₁ =  4/3(πr₁³)  =  4/3(π3³) and

V₂ =  4/3(πr₂³) =  4/3(π5³)

V₁/V₂ = 4/3(π3³)/4/3(π5³)

 = 3³/5³ = 27/125

Therefore  the ratio of their volumes = 27 : 125

If player 2 puts in two dollars and players 1 and 3 one dollar each, that should even up the odds. Now you want it just to be fair. So I think player 2 has to put up 2 dollars and players 1 and 3 each put up one. The pot is 4 dollars each time it is played.

Spinner 3 is not fair either. Player one has 2 chances. Player 2 has 3 chances and player 3 has but one chance. There are 6 chances in all. Player 1 should put up 2 dollars to play player 1 should put up 3 dollars and player 1 should put up 1 dollar.

Lines m and n are parallel. What is the measure of angle 4?

Answers

Answer:

132 deg

Step-by-step explanation:

from diagram, if lines m and n are parallel, then angle 3 = angle 7 and angle 4 = 132deg

Final answer:

The measure of angle 4 depends on its relationship to other angles in the diagram. If angle 4 is an alternate interior angle to another angle whose measure we know, it would share that measure.

Explanation:

To find the measure of angle 4 given that lines m and n are parallel, we need to understand a concept in geometry called alternate interior angles. According to this concept, when a line (called a transversal) intersects two parallel lines, the pairs of alternate interior angles it forms are equal. So, if angle 4 is an alternate interior angle to another angle whose measure we know, we can say that the measure of angle 4 is equal to that angle. Therefore, without knowing the measure of the corresponding angle, we can't provide a definitive measure for angle 4.

To make this more concrete, let's imagine we have a situation where lines m and n are parallel and line t is a transversal. We know the measure of angle 3 (on line m and intersected by t) is 75 degrees. If angle 4 is on line n and forms a Z shape with angle 3 (making them alternate interior angles), the measure of angle 4 would also be 75 degrees.

area of square = 5² = 25

note that the diameter of the circle = 5, thus radius = 2.5

area of circle = π × 2.5² = 6.25π

yellow region = 25 - 6.25π ≈ 5.4 ft²

You have a large tree in your front yard. At noon the tree casts a circular shadow with a radius of 9 m. You are now planting a tree in your back yard. At noon it's shadow will have a radius of 4 m. How much of your yard is shaded by the two trees at noon?

Answer:

  97π m² ≈ 304.7 m²

Step-by-step explanation:

The area of a circle is given by the formula ...

  A = πr²

The sum of the areas of the two circles is ...

  A = π(9 m)² + π(4 m)² = π(81 +16) m²

  = 97π m² ≈ 304.7 m²
