Answer:

8√13 units

Step-by-step explanation:

We use the distance formula.

The distance formula states that the distance between two points (x, y) and (a, b) is equal to:

d = [tex]\sqrt{(x-a)^2+(y-b)^2}[/tex]

Here, x = 6, y = -1, a = -18, and b = 15. Plug these in:

d = [tex]\sqrt{(x-a)^2+(y-b)^2}[/tex]

d = [tex]\sqrt{(6-(-18))^2+(-1-15)^2}=\sqrt{24^2+(-16)^2} =\sqrt{576 + 256} =\sqrt{832}[/tex] = 8√13

The answer is thus 8√13 units.

Answer:

28.8444102 or 28.8

Step-by-step explanation:

distance between  A (6, -1) and B ( -18, 15)

im just going to send a picture

I-18 + 6l = 24

l-1 + 15l = 16

24^2 + 16^2 = ?

576 + 256 = 832

the square root of 832 is 28.8444102 or 28.8

Answer:

X= 7

Step-by-step explanation:

x+x+2+3x-6=31 Combine x's

2x+2+3x-6=31 Continue to combine x's

5x+2-6=31  Combine whole numbers

5x-4=31  Add 4 to both sides

5x=35 Divide by 5

x=7

Answer:

The parts of the number are 200 and 320

Step-by-step explanation:

System of Equations

Suppose a and b are the two parts. They must meet two conditions:

[tex]a+b=520\qquad\qquad [1][/tex]

[tex]\displaystyle \frac{a}{b}=\frac{5}{8}\qquad\qquad [2][/tex]

From [1], we have:

[tex]b=520-a[/tex]

Replacing in [2]:

[tex]\displaystyle \frac{a}{520-a}=\frac{5}{8}[/tex]

Cross-multiplying:

[tex]8a=5*(520-a)[/tex]

Operating:

[tex]8a=2600-5a[/tex]

Joining like terms:

[tex]13a=2600[/tex]

Solving:

[tex]a=2600/13=200[/tex]

a=200

Since:

[tex]b=520-a\Rightarrow b=520-200[/tex]

b=320

The parts of the number are 200 and 320

Answer:

200 and 320

Answer:

1.875 mi/h

Step-by-step explanation:

We first convert 5280 feet to inches which is 63360 inches. Next, we divide 63360 inches by 33 inches which is 1920. To find this in minutes, we do 1920/60 which equals 32 minutes. Last, we divide 60 by 32 and get 1.875. Therefore, John walks 1.875 miles per hour.

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Quadratic formula goes as follows [tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] and [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex], there is no plus or minus (+/- thingy) sign on here but use both plus and minus on the numerator where I switched the signs.

The equation you give is [tex]3x^2-3x+\frac{3}{4}[/tex], to make it nice, multiply everything by 4 to cancel out the fraction and end up with [tex]12x^2-12x+3[/tex]. So a=12, b=-12, and c=3. Use these values and plug them into quadratic formula.

For the first formula I wrote, [tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex], you get [tex]\frac{-(-12)+\sqrt{(-12)^2-4(12)(3)} }{2(12)}[/tex]= [tex]\frac{1}{2}[/tex].

For the second formula, [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex], you get [tex]\frac{-(-12)-\sqrt{(-12)^2-4(12)(3)} }{2(12)}[/tex]= [tex]\frac{1}{2}[/tex].

Always do quadratic formula for both plus and minus to get both zeros. However, in this case, the answer still remained positive. So the zero of this would be just  [tex]\frac{1}{2}[/tex].

Answer:The walnuts weigh 31 pounds PER CRATE!!!!

Step-by-step explanation:

The amount of weight of the walnuts alone will be 620 pounds.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Twenty full crates of walnuts weigh 820 pounds, whereas an empty crate weighs 10 pounds.

Then the amount of the weight of the walnuts alone will be

⇒ 820 - 10 x 20

⇒ 820 - 200

⇒ 620 pounds

The amount of weight of the walnuts alone will be 620 pounds.

Answer:

Step 3

Step-by-step explanation:

Answer:

a. The amount by which the temperature changed from 7 p.m. to 7 a.m. is  -12 degrees Fahrenheit

b. The change in temperature each hour is -1 degrees Fahrenheit each hour

Step-by-step explanation:

The temperature at 7 p.m. last night = 10 degrees Fahrenheit

At 7 a.m. the next morning, the temperature = -2 degrees Fahrenheit

a. The amount, ΔT, by which the temperature changed from 7 p.m. to 7 a.m. is given as follows;

ΔT = (-2  - 10)  degrees Fahrenheit = -12 degrees Fahrenheit

b. Given that the temperature changed by a steady amount over night, w have, the change each hour is given as follows;

The change in temperature each hour = (The change in temperature)/(The time duration for the change)

We note that the change in time from 7 p.m. last night to 7 a.m. the next morning = -(7 - 19) = 12 hours (The minus sign is used because the 7 a.m. in the morning is higher than the 19 hours in the previous night

The change in temperature each hour = ΔT/(19 - 7) = -12/12 = -1 degrees Fahrenheit each hour.

x≥-3

Step-by-step explanation:

-4x-10≤2

-4x≤2+10

-4x≤12

x≥12÷-4 (The sign flips around when you divide by a negative number.)

x≥-3

Step-by-step explanation:

h(x) = x^2 - 5x + 7

(a) h(2) = (2)^2 - 5(2) + 7

= 4 - 10 + 7

= 1

(b) h(-5) = (-5)^2 - 5(-5) + 7

= 25 + 25 + 7

= 57

(c) h(-8) = (-8)^2 - 5(-8) + 7

= 64 + 40 + 7
