How do i solve for AB and CD?
Amanda [17]

Answer:

This is solved by Distance Formula

D²=(x2_x1)²-(Y2-y1)²

So D²= (-5-0)²-(1-1)²

D²=25

We can solve D by square root so

D=5

the Distance or length between a and b was 5

you can solve for c and d in a such way

Thanks in Advance

Identify whether each equation has no solution, one solution, or infinitely many solutions.
butalik [34]

Answer:

  1. infinitely many
  2. one solution
  3. no solution
  4. one solution

Step-by-step explanation:

1. 4x−x=2x+x

Simplifies to 3x = 3x, which is true for all values of x. Hence there are infinitely many solutions.

___

2. 2x+1=5

True only for x=2; one solution.

___

3. 4x+2=5x−x+4

Simplifies to ...

  4x +2 = 4x +4

  2 = 4 . . . . . . . not true for any value of x; no solution.

___

4. 2(x+4)=4(x+2)

Simplifies to ...

  2x +8 = 4x +8

  0= 2x . . . . . . . . . subtract 2x+8

True only for x=0; one solution.

what is the probability that s+d>3 and s.d>3? write your answer as a decimal rounded to hundreth place
maw [93]

The probability that s+d > 3 and sd > 3 is 0.03.

<h3>Solution</h3>

Plot the inequalities

The region -5 ≤ s,d ≤ 5 is the square shaded in grey.

The region s + d > 3 is the region Q shaded to the right of the straight line.

The region sd > 3 is the region R shaded to the right of the curve d = 3/s.

Find the intersection of the three regions

From the figure, the region satisfying all the above three inequalities is the region to the left of the curve d = 3/s, bounded by the square region, i.e. the region R.

Probability of region R

The required probability is the Geometric probability of the intersection region R. It is calculated as

P(R) = ar(region R) / ar(square region P).

Calculate the areas of the regions

ar(region R) = area of the rectangle to the right in the first quadrant formed by dropping a vertical from point F - area under the curve d = 3/s in the first quadrant

\[\Rightarrow \;\; \mathrm{ar(\mathbf{R}) =} \int_{3/5}^5\frac{3}{s}ds = 25-3-3\ln\frac{25}{3} = 15.64.\]

ar(region P) = 25 × 25 = 625.

Calculate P(R)

The probability of the region R, P(R) = 15.64 / 625 = 0.025.

Rounding it to the hundredth place of decimal, P(R) = 0.03.

The probability that s+d >3 and sd>3, where -5 < s,d < 5, is 0.03.

Nate has $50 to spend at the grocery store. He fills his shopping cart with items totaling $46. At checkout he will have to pay
Deffense [45]

Answer:

yes

Step-by-step explanation:

Find the amount of the sales tax:

46 x 0.06 = 2.76

Add the sales tax to the items total:

46 + 2.76 = 48.76

50 > 48.76

Since $48.76 is less than $50 he has enough money
