Answer:

2×2+x+1=0

4+x+1=0

5+x=0

x=-5

Answer:

That is a 45-45-90 triangle next to a 30-60-90 triangle.  

So, the height of the left triangle equals 5.

That makes the short side of the 30-60-90 triangle also equal to 5.

In a 30-60-90 triangle, the hypotenuse (or "x") is exactly twice the length of the shortest side.

Therefore, the hypotenuse (or "x") equals 10.

Answer:

12.58

Step-by-step explanation:

the 8 is in the hundredth's place, and 2 is less than 5, so the 8 stays the same and you eliminate all the numbers to the right, so you get 12.58

Answer:

So 2t%5E2%2B4t-30 completely factors to 2%28t%2B5%29%28t-3%29.

In other words, 2t%5E2%2B4t-30=2%28t%2B5%29%28t-3%29.

Note: you can check the answer by expanding 2%28t%2B5%29%28t-3%29 to get 2t%5E2%2B4t-30 or by graphing the original expression and the answer (the two graphs should be identical).

[tex]y=x^2-4x+6\\y'=2x-4[/tex]

To find the slope/gradient of the curve at the specific point, we use the derivative.

Then substitute x = 3 in y' = 2x-4

[tex]y'=2(3)-4\\y'=6-4\\y'=2[/tex]

Therefore, the slope/gradient of y = x²-4x+6 at (3,3) is 2.

Answer:

10

Step-by-step explanation:

x³=1000

x=3√1000

x=10

Answer:

x = 10   or   x = -5 + 5*i*sqrt(3)   or   x = -5 - 5*i*sqrt(3)

Step-by-step explanation:

x^3 = 1000

x^3 - 1000 = 0

(x - 10)(x^2 + 10x + 100) = 0

x = 10 or x^2 + 10x + 100 = 0

x = 10 or x^2 + 10x + 25 = -100 + 25

x = 10 or (x + 5)^2 = -75

x = 10 or x + 5 = sqrt(-75) or x + 5 = -sqrt(75)

x = 10   or   x = -5 + 5*i*sqrt(3)   or   x = -5 - 5*i*sqrt(3)

Answer:

2250 m

Step-by-step explanation:

30 cm = 0.3 m

1 : 75  :: 0.3 : x

Product of extremes = product of means

1 *x = 75 * 0.30

   x = 75 * 0.30

 x = 22.5 m

Answer:

22.5 m

Step-by-step explanation:

Convert to meters

.3 / x = 1/75

multiply .3 by 75 to get 22.5 m

Answer:

562000

Step-by-step explanation:

commission=commission rate multiplied with selling price

suppose selling price as x

14050=2.5% . x

14050=(2.5/100) . x

14050 . 100= 2.5 . x

x = 1405000/2.5

x=562000

Answer:

M = -2/5

Step-by-step explanation:

To find the slope of a line when you know two points, use the following formula.

M = y₂ - y₁ ÷ x₂ - x₁

M = 9 - 11 ÷ -12 - (-17)

M = -2 ÷ 5

M = -2/5

Answer:

198 yards

Step-by-step explanation:

Sean wants the sting of each balloon to be 9 feet, and he wants to get a total of 66 balloons.

The total length of stings required for 66 balloons would be;

total length of balloon strings = 66 x 9 feet

                                                 = 594 feet

But the string is sold by the yard at the store.

So that,

1 yard = 36 inches = 3 feet

x yard = 594 feet

Thus,

x = [tex]\frac{594}{3}[/tex]

  = 198 yards

x = 198 yards

Therefore, the total length of string that Sean would need is 198 yards.

Answer:

1/3 cup of ice icream

Step-by-step explanation:

This is a proportions question. Since we know that we need 1/4 cup of ice cream for every 3/4 cup of root beer, we need to find how many cups of ice cream we need for 1 cup of root bear.

We need to find out what times 3/4 makes 1. This can be done with:

(3/4)x = 1

x = 4/3

Now multiply that with 1/4 to get the amount of ice cream.

4/3 times 1/4 = 1/3

Answer:

He initially has $50 on his card.

For each night that he goes to play, $10 are discounted from the card, then if he went x nights to play, the amount of money that there is in the card is:

b(x) = $50 - $10*x

Now, notice that x must be a whole number because this measures the number of nights that he went to play, and we can not have rational numbers to describe this.

Then the domain of this function will be discrete (and this implies that the range must also be discrete)

Where the possible values of x are:

{0, 1, 2, 3, 4, 5}

(after x = 5, there is no more money in the card)

And the possible values of b(x) are:

{$0, $10, $20, $30, $40, $50}
