Answer:

z > -108.5

Step-by-step explanation:

1. z/7+19>3.5

Subtract 19 from both sides

2. Z/7 > -15.5

Multiply both sides by 7

3. Z > -108.5

Answer: its answer 3, most likely

Step-by-step explanation: i remember this question

Answer:

x = 4.5

Step-by-step explanation:

Let's solve this together!

First you would want to multiply 6 and x:

6×2 = 12

x×2 = 2x

Then you would want to subtract 12 from 3:

3+12 = 9

Then divide 9 by 2:

9÷2 = 4.5

That's it!

Hope this helped! :)

Answer:

w=10

Step-by-step explanation:

8.25+1/4w=10.75

8.25+0.25w=10.75

0.25w=10.75-8.25

0.25w=2.5

w=10

Answer:

C/10

Step-by-step explanation:

Answer:

0,0

Step-by-step explanation:

The point Q was rotated about the origin (0,0) by -45 degrees, so the new coordinate point is (√2, 4√2).

From the given graph, the coordinates of point Q are (-3, 5).

Rotating the co-ordinate axes through an angle of 45° in anti-clockwise direction is equivalent to rotating the point through an angle of -45° about origin.We will use rotation from complex numbers to solve this.

Let x + iy the new complex number

(-3+5i)[tex]e^{\frac{-\pi i}{4} }[/tex]

= (-3+5i)((1-i)/√2)

= (-3+5i)(1-i) ×1/√2

= (-3+5i+3i-5i²) ×1/√2

= (-3+8i+5) ×1/√2

= (2+8i) ×1/√2

= (2/√2 + 8i/√2)

= (√2 + 4√2i)

So, the coordinates are (√2, 4√2)

Therefore, the point Q was rotated about the origin (0,0) by -45 degrees, so the new coordinate point is (√2, 4√2).

Answer:

Please check the explanation.

Step-by-step explanation:

Writing this relation in set notation using curly braces:

{(1, 3), (2, 5), (3, -1), (4, 0), (5, 6)}

The relation clearly indicates that each input is related to exactly one output. In other words, there is no repetition of 'x' values.

Hence, this relation is a function.

We know that the domain is the set of all x values.

Thus, the domain is: {1, 2, 3, 4, 5}

We know that the domain is the set of all y values.

Thus, the range is: {-1, 0, 3, 5, 6}

Answer:

[tex]x=\dfrac{|-246.875-121.175|}{5}[/tex]

Step-by-step explanation:

Given that:

Same distance is drilled by the oil drilling company for 5 days.

Initial elevation = 121.175 feet

Final elevation = -246.875 feet

To find:

The equation to find the value of [tex]x[/tex] i.e. the distance drilled each day?

Solution:

To find the distance drilled each day, we need to divide the total distance drilled with the number of days taken to drill the total distance.

Total distance drilled can be found by subtracting the initial elevation from the final elevation and taking modulus because distance can not be negative.

Total distance drilled = | Final elevation - Initial elevation |

Total distance drilled = | -246.875 - 121.175 |

Therefore, we can write the expression as:

[tex]x=\dfrac{|-246.875-121.175|}{5}[/tex]

[tex]\Rightarrow x=\dfrac{|-368.05 |}{5} =73.61\ ft/day[/tex]

General Formulas and Concepts:

Algebra I

Calculus

Step-by-step explanation:

Step 1: Define

[tex]f(x) = \frac{1}{\sqrt{800-2x} }[/tex]

Step 2: Identify Variables

Using U-Substitution, we set variables in order to integrate.

[tex]u = 800-2x\\du = -2dx[/tex]

Step 3: Integrate

Step 4: Identify Domain

We know from a real number line that we cannot have imaginary numbers. Therefore, we cannot have any negatives under the square root.

Our domain for our integrated function would then have to be (-∞, 400]. Anything past 400 would give us an imaginary number.

Answer:

6,000

Step-by-step explanation:

If you are from k12 this is correct

Since you're only given the one vector, I assume you're supposed to find the magnitude of v, or ||v||, using the dot product.

We have

v • v = (-2, -1) • (-2, -1) = (-2)² + (-1)² = 5

so that

||v|| = √(v • v) = √(5)

Step-by-step explanation:

Use the FOIL method

First - multiply the first numbers inside the parentheses (y^2 and -2y)

Outer- multiply the first and last numbers inside the parentheses (y^2 and 7)

Inner - multiply the two numbers next to the closing and opening parentheses (6 and -2y)

Last- multiply the last two numbers in the parentheses. (6 and 7)

Then simplify to put it in standard form.

Answer:

the square of -5 is 25 not -25

, -4(1)(-3) is 12 not -12 because when we multiply 2 negative numbers their result is positive

+5 should be written instead of -5

Step-by-step explanation:

+5 should be written instead of -5 as the formula is (-b+-(b²-4ac)½)/2a . since b=-5 ;-b=+5

Answer:

54

Step-by-step explanation:

So If this tells you what 'm' and 'n' are, you just put them inside.

First do the M so then it will be 5 * 10 which is 50 then we just first leave it there.  Then we start putting in that N. We know that N is 4. Then it's N to the power of 2. I recommend since there's already a 4 on the bottom, just do 4 * 4 there. Then you see there is a 4 on the denominator while there are double 4's on the numerator. Then you just cross one 4 on the denominator and one on the numerator to simplify it.

Then all there is is 50 + 4 = 54

So 54 is our answer.

Answer:

Step-by-step explanation:

10m + n^2/4           (m=5 , n=4)

50 + 4 =

54

Answer:

Yes

Step-by-step explanation:

Plug in 4 for x, 5 for y. if it equals, then its a point

5 = -2(4) + 13

5 = -8 + 13

5 = 5

it equals so (4,5) is a point

Answer:

[tex]\frac{11}{42}[/tex] or 26.19%

Step-by-step explanation:

If the range of possible numbers is between 12 and 54 then that means that there are 42 (54 - 12) possible numbers that can be made. In this range, there are 11 prime numbers which are the following...

13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53

Therefore, the probability that the number formed is a prime would be [tex]\frac{11}{42}[/tex] which if we divide and multiply the decimal by 100 we get the probability in percentage form.

[tex]\frac{11}{42}[/tex] = 0.2619

0.2619 * 100 = 26.19%

Finally, we can see that the probability of this happening is 26.19%

Answer:

Shane has 9 sweats now.

Step-by-step explanation:

Given that Shane and Gemma share 35 sweets in the ratio 1:4.

Let the share of Shane be = 'x'

Let the share of Gemma be = '4x'

The combined share of Shane and Gemma = x + 4x = 5x

Total sweets they share = 35

so the equation becomes

5x = 35

x = 7

Thus,

Share of Shane = x = 7

Share of Gemma = 4x = 4(7) = 28

Gemma eats 10 sweets, so she has left with 28-10 = 18 sweets

Gemma gave 2 of the sweets she has left.

As Shane has already 7 sweats, so adding 2 in 7 sweats would make it 9 sweats.

Therefore, Shane has 9 sweats now.
