Solve In Order Of OperationThanks

Answers

Answer 1

Answer:

b) 31 and c) 11

Step-by-step explanation:

IMPORTANT: Order of operations is PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/SUbtraction).

B) Solve inside the parentheses first.

1. 2^3 - 6 = (2*2*2) - 6 = 2.

2. Now the equation looks like 3 + 7 (2)^2, Next we need to do exponents.

3. 2 to the power of 2 is 4, leaving you with 3+7(4)

4. Now multiply 7*4, which is 28 then add 3 to it.

So B) would ultimately be 31.

C) As we did in equation B, we start with parentheses.

1. (6/3) we can just simplify this to 2, so those parentheses are out of the way.

2. Now we need to do exponents, (-3)^2. This is the same as -3 * -3. This would equal 9.

3. So far the equation looks like 4 + 9 - 2 / 2.

4. Next would be to solve any multiplication/division problems we have. We can see from step 3 that we have a -2 divided by a positive 2. This would give us -1.

5. Now the equation looks like 4 + 9 - 2. Now you can just working from left to right.

So C) would solve to 11

A. [tex] x \leq -16[/tex]  

B. b > 11

C. [tex] c \leq -13 [/tex]

D. [tex] x \geq -9[/tex]

Step-by-step explanation:

Given the following algebraic expression;

A. [tex] \frac {3x}{4} \leq 12 [/tex]

We would simplify the equation by multiplying all through by 4;

[tex] 4 * \frac {-3x}{4} \leq 12 * 4[/tex]

[tex] -3x \leq 48[/tex]

Divide both sides by -3;

[tex] x \leq -16[/tex]

B. 5b - 28 > 27

Rearranging the equation, we have;

5b > 27 + 28

5b > 55

Divide both sides by 5

b > 11

C. [tex] 13c \leq -169[/tex]

Divide both sides by 13

[tex] c \leq -13 [/tex]

D. [tex] 3x - 7 \geq 4x + 2[/tex]

Collecting like terms, we have;

[tex] 3x - 4x \geq 2 + 7[/tex]

[tex] -x \geq 9[/tex]

Divide both sides by -1

[tex] x \geq -9[/tex]

From the roof of a building, a ball is thrown into the air. The height of the ball, h, in
metres after t seconds is given byh = -t2 + 4t + 12.
a) What is the height of the building?
b) How long will it take for the ball to hit the ground?
c) What is the maximum height of the ball and when does it occur?
d) When will the ball have a height of exactly 7m above the ground?

Answers

Answer:

a) The height of the building is 12 metres.

b) The ball will take 6 seconds to hit the ground.

c) The maximum height of the ball is 16 metres and occurs 2 seconds after launch.

d) The ball have a height of 7 meters above the ground 5 seconds after launch.

Step-by-step explanation:

a) The roof of the building is represented by the initial height of the ball according to the function. If we know that [tex]t = 0\,s[/tex], the height of the building, measured in metres, is:

[tex]y = -(0\,s)^{2}+4\cdot (0\,s) + 12[/tex]

[tex]y = 12\,m[/tex]

The height of the building is 12 metres.

b) Let equalise the given polynomial and solve for [tex]t[/tex] to determine the time taken for the ball to hit the ground:

[tex]-t^{2}+4\cdot t +12 = 0[/tex] (1)

By the Quadratic Formula, we find the following solutions:

[tex]t_{1} = 6\,s[/tex] and [tex]t_{2} = -2\,s[/tex]

Since time is a positive variable, then the only solution that is physically reasonable is:

[tex]t = 6\,s[/tex]

The ball will take 6 seconds to hit the ground.

c) The maximum height of the ball occurs when speed is equal to zero. First, we differentiate the function and equalise to zero:

[tex]-2\cdot t + 4 = 0[/tex] (2)

[tex]t = 2\,s[/tex]

Lastly, we evaluate the function at given time:

[tex]y = -(2\,s)^{2}+4\cdot (2\,s)+12[/tex]

[tex]y = 16\,m[/tex]

The maximum height of the ball is 16 metres and occurs 2 seconds after launch.

d) We equalise the height formula to seven and solve the resulting polynomial:

[tex]-t^{2}+4\cdot t + 12 = 7[/tex]

[tex]-t^{2}+4\cdot t +5 = 0[/tex] (3)

By the Quadratic Formula, we get the following solutions:

[tex]t_{1} \approx 5\,s[/tex] and [tex]t_{2} \approx -1\,s[/tex]

The only solution that is physically reasonable is [tex]t = 5\,s[/tex].

The ball have a height of 7 meters above the ground 5 seconds after launch.

Answer:

Step-by-step explanation:

Complex Numbers

Complex numbers can be expressed in several forms. One of them is the rectangular form(x,y):

[tex]Z = x+\mathbf{i}y[/tex]

Where

[tex]\mathbf{i}=\sqrt{-1}[/tex]

They can also be expressed in polar form (r,θ):

[tex]Z=r(\cos\theta+\mathbf{i}\sin\theta)[/tex]

The polar form is also shortened to:

[tex]Z = r CiS(\theta)[/tex]

The product of two complex numbers in polar form is:

[tex][r_1Cis(\theta_1)]\cdot [r_2Cis(\theta_2)]=r_1\cdot r_2Cis(\theta_1+\theta_2)[/tex]

We are given the complex numbers:

2(cos(45°) + i sin(45°)) and 5(cos(30°) + i sin(30°))

They can be written as:

2CiS(45°) and 5CiS(30°). The product is:

2CiS(45°) * 5CiS(30°) = 10CiS(75°)

Expressing back in rectangular form:

[tex]\boxed{2CiS(45^\circ) \cdot 5CiS(30^\circ) =10(\cos 75^\circ+\mathbf{i}\sin 75^\circ)}[/tex]

At a hardware store, a tool set normally cost $80. During a sale this week, the tool set costs $12 less than usual.

What percentage of the usual price is the saving? Explain or show your reasoning.

Answers

Answer:

15 % of usual price is a savings

Step-by-step explanation:

Given that tool set normally cost $80

During the sale this week the tools that cost $12 less than usual

To find: what percentage of the usual price is a savings

From given information,

Usual price of tool set = $ 80

Given that tools that cost $12 less than usual which means she saved $ 12

Savings = $ 12

To find what percentage of the usual price is a savings, we can solve by framing a expression,

Let "x" be the required percentage

Then x % of percentage is equal to savings price

x % of usual price = savings price

x % of 80 = 12

Therefore 15 % of usual price is a savings

Answer:

Answer is 15%

Step-by-step explanation:

You have to do a proportion

12. = x

80 100 and u have to cross multiply

80x = 1200

80. 80

then divide 1200÷80=15

M is the midpoint of AN, A has coordinates

the coordinates of N.
Help explain pls?

Answers

Answer:   (-1, -6)

==========================================================

Explanation:

Let's focus on the x coordinates of each point for now.

Point A has x coordinate -7Point N has an unknown x coordinate. We leave it as x for now.Point M has x coordinate -4

The idea to find the midpoint's coordinates is to add up the endpoints coordinates and divide by 2.

So we'll add up -7 and x, then divide by 2 to get the midpoint x coordinate of -4

In short we have:  (-7+x)/2 = -4

Solving for x leads to...

(-7+x)/2 = -4

-7+x = 2*(-4)

-7+x = -8

x = -8+7

x = -1

This is the x coordinate of point N

-------------------------------

We'll repeat the same idea and steps for the y coordinates

Point A has y coordinate 4Point N has y coordinate unknown. Leave it as y for now.Point M has y coordinate -1

So,

(4+y)/2 = -1

4+y = 2(-1)

4+y = -2

y = -2-4

y = -6

This is the y coordinate of point N.

------------------------------

In summary, we found that point N is located at (-1, -6)

Point A is (-7,4) and point N is (-1,-6)

If you apply the midpoint formula to those two points, you should find the midpoint to be M(-4,-1) which helps confirm the answer.

Another way to confirm the answer is to compute the distance from A to M, which finds the length of segment AM. Do the same for segment MN. You should find that both segments are the same length.

The diagram below is a visual way to check. Starting at point A and moving down to point B, we moved 5 units. Then go from B to M and you'll move 3 units to the right. This pattern "down 5, right 3" is applied again when we go from M to C to N in that order. This effectively creates two congruent triangles (ABM and MCN) which can lead to proving AM = MN.

In short: the red piece of the graph is the same length as the blue piece; this confirms we have the correct answer.

Step-by-step explanation:

According to Question , M is the midpoint of AN, A has coordinates (-7,4), and M has coordinates (-4, -1).

Figure :-

[tex] \setlength{\unitlength}{1 cm}\begin{picture}(20,12) \put(4,0.2){\line(0,-1){0.4}}\put(1,0){\line(1,0){6}} \put(3.8,-0.6){$\bf M(-4,-1) $} \put(1,-0.6){$\bf A (-7,4)$} \put(6.8,-0.6){$\bf N(x,y)$} \end{picture}[/tex]

Let the coordinates of N be ( x , y )

Now , according to Midpoint Formula , the midpoint of points say A(x , y) and B (x' , y') is given by ,

[tex]\boxed{\blue{ \bf Midpoint =\bigg( \dfrac{x+x'}{2} , \dfrac{y+y'}{2} \bigg) }}[/tex]

On using this formula ,

[tex]=> Midpoint = \bigg( \dfrac{x+x'}{2} , \dfrac{y+y'}{2} \bigg) \\ \\ => (-4, 1) = \bigg( \dfrac{x -7 }{2} , \dfrac{y + 4 }{2}\bigg) \\ \\ => -4 = \dfrac{x-7}{2} \\\\ => x - 7 = -8 \\\\ => x = 7 -8 \\\\ \boxed{\red{\sf=> x = -1 }} \\\\ => \dfrac{y+4}{2}=-1 \\\\=> y +4 = -2 \\ \\ y = -4-2 \\\\\boxed{\red{\sf=> y = -6 }}[/tex]

In a game, the probability that a spinner will land on a 2 is 1/3. How many times would you expect to land on a 2 if you spin the spinner 6 times?

Answers

Answer:

2 times

Step-by-step explanation:

The probability of 1/3 means that the spinner will land on a 2, 1/3 of the time:

We can predict how many times it will land on a 2 by finding 1/3 of 6:

6/3

= 2

So, the spinner will land on a 2, two times

Number of times probability of landing on a 2 is 2, when you spin the spinner 6 times.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, in a game, the probability that a spinner will land on a 2 is 1/3.

If you spin the spinner 6 times, probability of landing on a 2 is

1/3 ×6

= 2

Therefore, number of times probability of landing on a 2 is 2.

Step-by-step explanation:

A store has a 10% off sale on pants. With this discount, the price of one pair of pants before tax is $17.10 What was the original price of the pants?

Let x represent the original price of the pair of pants

From the question, we know that:

10% of x = $17.10

10/100 × x = $17.10

10x/100 = $17.10

Cross Multiply

10x = 100 × $17.10

10x = 1710

x = 1710/10

x = $171

Hence, the original price of the pants = $171
