The expression below is equivalent to: 2xi (5xi 2 - 3i)

1) 10x^2 - 6x

2) 10xi^3 - 3i

3) 6x - 10x^2i

4) 7x²i^3 - xi​

There are a couple of ways to do this. The easiest is to take the number of degrees between 42 and - 54 and divide by 12.

Method

the number of degrees is abs(42) + abs(-54) = 42 + 54 = 96

Now divide by 12

Hours = 96 / 12 = 8 hours.

Answer:

[tex]f(x) = x - 3[/tex]

Step-by-step explanation:

Linear equation form:

[tex]y=mx+b[/tex]

m is the slope

b is the y intercept

Solve for m using the first two points:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

[tex]m=\frac{6-7}{3-4}[/tex]

[tex]m=\frac{-1}{-1}[/tex]

[tex]m=1[/tex]

Plug in m and either point into the equation and solve for b:

[tex]y=mx+b[/tex]

[tex]4=1(7)+b[/tex]

[tex]4=7+b[/tex]

[tex]b=4-7[/tex]

[tex]b=-3[/tex]

Final equation:

[tex]y=x-3[/tex]

Test with the 3rd point:

Answer:

x = - 23.57 (appx)

Step-by-step explanation:

[tex]( \frac{ - 7}{3} )x - 3 = 52[/tex]

[tex] = > ( \frac{ - 7}{3} )x = 52 + 3 = 55[/tex]

[tex] = > x = 55 \div ( \frac{ - 7}{3} )[/tex]

[tex] = > x = \frac{55 \times 3}{ - 7} = \frac{165}{ - 7} = - 23.57(appx)[/tex]

Answer:

This is 0.14 to the nearest hundredth

Step-by-step explanation:

Firstly we list the parameters;

Drive to school = 40

Take the bus = 50

Walk = 10

Sophomore = 30

Junior = 35

Senior = 35

Total number of students in sample is 100

Let W be the event that a student walked to school

So P(w) = 10/100 = 0.1

Let S be the event that a student is a senior

P(S) = 35/100 = 0.35

The probability we want to calculate can be said to be;

Probability that a student walked to school given that he is a senior

This can be represented and calculated as follows;

P( w| s) = P( w n s) / P(s)

w n s is the probability that a student walked to school and he is a senior

We need to know the number of seniors who walked to school

From the table, this is 5/100 = 0.05

So the Conditional probability is as follows;

P(W | S ) = 0.05/0.35 = 0.1429

To the nearest hundredth, that is 0.14

Answer: The pattern of the sequence is to subtract 11 from the last number.

Step-by-step explanation: The next two terms of the sequence are 55 and 44.

Answer:

The explicit function is: [tex]P_x = 153+3x[/tex]

And the number of lights after 33 weeks will be 252.

Step-by-step explanation:

Given that:

Total street lights = 153

Let x be the number of weeks

Then the number lights after x weeks will be 3x

This is a linear function where the y-intercept is 153 and slope is 3.

It can be written as: y = mx+b

The function is:

[tex]P_x = 153+3x[/tex]

Putting the values for x will give us the number of total lights after that number of weeks.

To find, how many street lights were there at the end of 33rd week,

Putting x = 33

[tex]P_{33} = 153+ 3(33)\\= 153+99 = 252[/tex]

Hence.

The explicit function is: [tex]P_x = 153+3x[/tex]

And the number of lights after 33 weeks will be 252.

Answer:

$149.27

Step-by-step explanation:

Find the tip first, so:

126.5 · 18/100 = 2277/100 = 22.77

Now that we found the tip, just add that with the bill:

$126.50 + $22.77 = $149.27

Step-by-step explanation:

This is the answer...

Answer: n = 4

Step-by-step explanation:

1. Distribute on the right side of the equation

-2(1-7n) = -2 + 14n

2. Subtract 5n from each side

5n + 34 = -2 + 14n

34 = -2 + 9n

3. Add 2 to each side

34 = -2 + 9n

36 = 9n

4. Divide each side by 9 to isolate the variable n

36 = 9n

4 = n

Answer: 14 days

Step-by-step explanation:

[tex]2.5x +6 =41\\ -6 -6\\2.5x = 41\\\\\\2.5\\x=14[/tex]

Answer:

Let X be number of days

Let Y be total amount of pages

21x=y

Step-by-step explanation:

So we know that Arnold reads 21 pages a day

But we don’t know how many days

THe number of pages can change expending on the amount of days he reads

So lets make that y.

So 21x=y is the equation unless they ask for different interpatations of the variables (x,y,z)

x(9)-3(9)--->distributive property

Answer:

(-7,-16)

Step-by-step explanation:

calculate the first derivative and equale tot zero.

dy/dx = 2x + 14 = 0

<=> x = -7

calculate now the value of y for x = -7

y = (-7)^2 + 14*(-7) + 33

y = 49 - 98 + 33

y = -16

Answer:x^2-y^2

Answer:

130

Step-by-step explanation:

So there's only only 2 candidates, 35% of the students voted for Leandro that means that 65% of the students voted for Gerardo as 100% - 35% = 65%

70 is 35% of the students, therefore we need to find a factor where we can multiply 35% to be 100%, so we can multiply it with 70 as well, to find all the students. 100 divided by 35 is 2.85714285714. Now we have to multiply 70 with that number. 70 times 2.85714285714 is 200.

Okay so 70 students voted for Leandro, and there are 200 students in total. So now we subtract to find how many voted for Gerardo. 200 - 70 = 130

130 students voted for Gerardo

Answer:

Positive

Step-by-step explanation:

Slope is positive because the line is increasing from left to right. If the line was decreasing (pointing downwards) from left to right, its slope would be negative.

A slope that is zero would be a straight, horizontal line while a line with no slope would be a straight, vertical line.

Answer: 41

A prime number only has two factors: 1 and itself

A composite number has more than two factors.

Let's identify the following numbers:

24 is composite because it has factors like 2, 3, 8, and 12.

16 is composite because it has factors like 8, 2, and 4.

64 is composite because it has factors like 2, 24, and 8.

41 is prime because it's factors are 1 and 41.

Answer:

gof(x) = 3

Step-by-step explanation:

Given that,

f(x) = x+2 and g(x) = x+1

We need to find gof(x).

gof(x) means g[f(x)].

g[f(x)] = g(x +2)

= x+2+1

= x+3

Hence, the value of gof(x) is 3.
