Question
The truth table represents statements p, q, and r. p q r q ∧ r A T T T T B T T F F C T F T F D T F F F E F T T T F F T F F G F F T F H F F F F If p is false, which row represents when p ∨ (q ∧ r) is true?
Solution 1

Solution:

q ∧ r : q and r

q      r        q∧r

T      T         T

T       F          F

F       T          F

F        F          F

p ∨ (q∧r)

p OR (q AND r)

p          q∧r          p∨(q∧r)

F           T∧  T=T      T

F            F∧T = F      F

F             T ∧ F=F      F

F             F ∧ F =F      F

If P is false , The row which represents  when p ∨ (q ∧ r) is true is →→F T T T

Question
An apple pie with a circumference of 28.26 inches is cut into 6 equal-sized pieces. Two pieces of the pie are eaten. What is the area of the pie that is left? Select the correct answer. Use 3.14 for π.
Solution 1
C = πd
d = C /
π
d = 28.26 / 3.14
d = 9 in

but r = d/2 = 9/2 = 4.5 in

A =
π r^2
= 3.14 x (4.5^2)
= 3.14 x 20.25
= 63.585

divided into 6 equal
so
63.585 / 6 = 10.5975

but ate 2, so there are 4 pieces left
4 x 10.5975 = 42.39

the area of the pie that is left is 42.36 in^2
Solution 2
Hey user!!

we know that circumference of circle = πd

given the circumference of the apple pie = 28.26 in.

therefore πd = 28.26 in.

==> 3.14 × d = 28.26 in.

==> d = 28.26/3.14

==> d = 9 in.

the diameter of the apple pie is 9 in.

therefore radius of the apple pie = 9/2 = 4.5 in.

area of the apple pie = πr²

== 3.14 × 4.5 × 4.5

= 63.585 in²

it's divided into 6 equal parts and two pieces are eaten. so the area of leftover pie = 63.585/6 × 4

= 63.585/3 × 2

= 21.195 × 2

= 42.39 in²

cheers!!

Question
Jonas is conducting an experiment using a 10-sided die. He determines that the theoretical probability of rolling a 3 is mc015-1.jpg. He rolls the die 20 times. Four of those rolls result in a 3. Which adjustment can Jonas make to his experiment so the theoretical and experimental probabilities are likely to be closer?
Solution 1
The link doesn't work, but I imagine he would have figured that there is a 1/10 chance of a 3 being rolled, assuming there are ten different numbers on the die.

Since he rolled the die 20 times, and 4 of those rolls were 3's, the experimental probability of him rolling a 3 are 1/5.

What I think he should do is: try the experiment 3 times, then gather the data of the experiments, and make his prediction.

Question
Choose the system of equations which matches the following graph: x+2y= −10 3x − y = 12 2) x − 2y = −10 3x − y = 12 3) x + 2y = −10 3x + y = 12 4) x − 2y = −10 3x + y = 12
Solution 1
The answer to this equation is the problem  3x - y = 12
Question
The surface area of a sphere is S(x) = 4πx2, where x is the length of the radius of the sphere. Restrict the domain to create a one-to-one function. Find and describe the inverse function
Solution 1
Given that the surface area of the sphere is S(x)=4πx², the inverse function will be obtain as follows: make x the subject of the function
S(x)/(4π)=x²
get the square root of both sides:
x=√[S(x)/(4π)]
replace x by S⁻¹(x) and S(x) by x
this will give us the inverse as :
S⁻¹(x)=√[x/(4π)]
The above implies that the inverse is the square root of the radius divided by 4π
Solution 2

The answer is .

Step-by-step explanation:

The input of is the surface area of a sphere; the output is the length of the radius.

Question
Evaluate the expression 2x - (4y - 3) + 5xz, when x = -3, y = 2, and z = -1
Solution 1
2x - (4y - 3) + 5xz, when x = -3, y = 2, and z = -1
plug in
= 2(-3) - [4(2)- 3] + 5(-3)(-1)
= -6 - 5 + 15
= 4

Question
When ordering a student desk priced at $69.00, the shipping charges are 6%. What is the total cost of the desk? Solution 1 Since the desk is$69.00 and the shipping charges are 6%

69*.06= 4.14

Your tax would be $4.14 so,$4.14+$69.00= A total of$73.14
Solution 2
Shipping charges = 6% x $69 = 0.06 x 69 =$4.14

Total cost = $69 +$4.14 = $73.14 Answer:$73.14
Question
A cross-section​ of a light reflector is a parabola. The bulb is located at the focus. Suppose the bulb is located 11 in from the vertex of the reflector. Use this information to make the following determinations. Model a cross section of the reflector by writing an equation of a parabola that opens upward and has its vertex at the origin.
Solution 1

An equation of a parabola that opens upward and has its vertex at the origin,

⇒ y² = - 8 x

### What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Now,

The equation of the parabola turned to the left is to the negative side of the coordinate system is:

⇒ y² = - 2 p x

where, p is the parameter of the parabola

The relationship between the parameter and the focus is.

⇒ p = 2 f

=> p = 2 × 2

⇒ p =  4 cm

Then, the equation of the parabola is:

y² = - 2 p x

= - 2 × 4 x

= - 8 x

Therefore, An equation of a parabola that opens upward and has its vertex at the origin,

⇒ y² = - 8 x
