How many different 5-digit numbers can you write using each of the digits 0, 1, 2, 3, 4 exactly once?

Answers

Answer:

96

Step-by-step explanation:

To get 5 digit numbers using the digits 0,1,2,3,4 exactly once = 4*4*3*2*1 = 96.

Step 1:

1st digit can be 1, 2,3,4 ( it can't be 0) so there are 4 choices.

Step 2:

2nd digit = 4 choices.

Step 3:

3rd digit = 3 choices

Step 4:

4th digit = 2 choices

Step 5:

5th digit = 1 choice .

So the number of different 5 digit number is 4*4*3*2*1 = 96

The difference between two positive numbers is 7 and the difference between thes
cubes is 805. If 'A' represents their product and 'B' represents the sum of their squares,
find the value of 'A-B'.​

Answers

Given :-

The  difference between two positive numbers is 7 and the difference between these  cubes is 805. If 'A' represents their product and 'B' represents the sum of their squares,

To Find :-

A - B

Solution :-

So,

Let the number be n and m

A = n × m = nm

B = n² + m² = (n + m)²

Now

n³ - m³ = 805

(n - m) (n² + m² + nm) = 805

Since difference is 7

7 × n² + m² + nm = 805

n² + m² + nm = 805/7

n² + m² + nm = 115

(n² + n) + (m² + m) = 115

A + B = 115

Now

On squaring the first eq.

(n - m)² = (7)²

(n - m)² = 49

B - 2A = 49

Now

A + B - B + 2A = 115 - 49

A + 2A = 66

3A = 66

A = 66/3

A = 22

By using 2

B - 2(22) = 49

B - 44 = 49

B = 49 + 44

B = 93

A - B = 22 - 93 = -71

write the equation -1/2x - 2y = -4 in slope intercept form​

Answers

Answer:

y= -1/4x+2

Step-by-step explanation:

y=mx+b is the slope intercept form.

We first must isolate y by adding 1/2x on both sides.

-2y=-4+1/2x

next we multiple by -1/2 to get rid of the -2

y=2-1/4x

y=-1/4x+2

James goes out to eat with Janet, and their meal costs $68. There is a sales tax of 7% and Janet wants to leave a 20% tip. How much money will Janet spend on the entire meal?

Answers

Answer:

$86.36

Step-by-step explanation:

Tax: 7%, or 0.07

Tip: 20%, or 0.2

Substitute the values:

Tip: 68 * 0.07 = 4.76

Tip: 68 * 0.2 = 13.6

Just the meal cost: 1 * 68 = 68

Add these all together

4.76 + 13.6 + 68 = 86.36

Thus, the total cost of the meal would be $86.36

Find the distance between the two points rounding to the nearest tenth (if necessary).
(-6, 6) and (-3,3)

Answers

Answer:

[tex]\boxed {\boxed {\sf d\approx 4.2}}[/tex]

Step-by-step explanation:

The formula for distance is:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]

Where (x₁, y) and (x₂, y₂) are the points.

We are given (-6, 6) and (-3, 3). If we match the value and its corresponding variable, we see that:

x₁= -6 y₁ = 6 x₂ = -3 y₂ = 3

Substitute the values into the formula.

[tex]d= \sqrt{ (-3 - -6)^2+(3-6)^2[/tex]

Solve inside the parentheses.

-3 --6 = -3+6 = 33-6 = -3

[tex]d= \sqrt{(3)^2+ (-3)^2[/tex]

Solve the exponents.

(3)²= 3*3= 9 (-3)²= -3*-3 =9

[tex]d= \sqrt{9+9[/tex]

Add.

[tex]d= \sqrt18[/tex]

[tex]d= 4.24264069[/tex]

Round to the nearest tenth. The 4 in the hundredth place tells us to leave the 2 in the tenth place.

[tex]d \approx 4.2[/tex]

The distance between the two points is apprximately 4.2

Consider a circle centered at C(0,0). If the point P(3,5) lies on the circle, then which of the following points also lies on the circle?
A. (-2,6)
B. (6,-[tex]\sqrt{5}[/tex])
C. (1,[tex]\sqrt{33}[/tex])
D. (-2[tex]\sqrt{2}[/tex],4)

Answers

Answer:

C

Step-by-step explanation:

First find the equation of the circle

the general formula for a circle (x-h)² + (y-k)² = r² where (h=0, k=0) are the coordinates of the center and r is the radius that we do not know

the distance between the center (0, 0) and the point (3,5) is the radius

distance formula d² = (x2-x1)² +(y2-y1)²  where (x1=0,y1=0) and (x2=3, y2=5)

d² = (3-0)² + (5-0)² = 3² +5² = 9+ 25 = 34 =r²

(x-0)² + (y-0)² = 34 ; x²+y² =34 is the equation of the circle

Second check if any of the points are on the circle by substituting x and y with de given coordinates.

A. for (-2, 6) we have (-2)²+6² =34 so 4+36 =34 false

B. for (6, -√5) we have 6²+(-√5)² =34 so 36+5=34 false

C. for (1, √33) we have 1²+(√33)² =34 so 1+33 =34 true

D. for (-2√2, 4) we have (-2√2)²+4² =34 so 8+16=34 false

Step-by-step explanation:

Given

[tex]\begin{array}{cccccc}x & {0} & {4} & {7} & {10} & {13} \ \\ y & {-5} & {-5} & {-5} & {-5} & {-5} \ \end{array}[/tex]

Solving (a): The domain

The x values represent the domain.

Hence, the domain is:

[tex]Domain =\{0,4,7,10,13\}[/tex]

Solving (b): The range

The y values represent the range

Hence, the range is:

[tex]Range = \{-5\}[/tex]

Solving (c): The function

By observation, we can see that for all values of x the value of y remains unchanged (-5)

Hence, the function is:

ABCD is a parallelogram. Which statements are true?

Answers

Answer:

Final Answer: Statements 1, 2 and 4 are correct.

Step-by-step explanation:

Finding value of y:

2y + 3 = 15 => 2y = 12 => y = 6;

Finding value of x:

6x + 5 = 77 => 6x = 72 => x = 12;

Statement Number 1:

y² > 2x ? => 6² > 2 * 12 ? => 36 > 24 ?

Yes, 36 is bigger than 24, therefore statement one is correct.

Statement 2:

x = 2y ? => 12 = 2 * 6? => 12 = 12?

Yes, 12 is equal to 12. Statement 2 is correct.

Statement 3:

x + 2 = y + 10 ? => 12 + 2 = 6 + 10? => 14 = 16?

No, 14 is not equal to 16. Statement 3 is incorrect.

Statement 4:

y + 4 > x - 4 ? => 6 + 4 > 12 - 4 ? => 10 > 8 ?

Yes, 10 is bigger than 8. Statement 4 is correct.
