Answer 2

Final answer:

The midpoint formula calculates the center point between two points on a coordinate plane, while the distance formula calculates the distance between two points using the Pythagorean theorem.

Explanation:

Understanding the Midpoint and Distance Formulas

The midpoint formula is used to find the exact center point between two defined points on a coordinate plane. To find the midpoint (M) between two points, (X1, Y1) and (X2, Y2), you use the formula:

M = ((X1 + X2) / 2, (Y1 + Y2) / 2)

For example, to find the midpoint between the points (2, 3) and (4, 8), you would calculate:

M = ((2 + 4) / 2, (3 + 8) / 2) = (3, 5.5)

The midpoint between these points is at coordinates (3, 5.5).

The distance formula, on the other hand, is used to determine the distance between two points on a coordinate plane.

The formula is derived from the Pythagorean theorem and is written as:

D = \(√((X2 - X1)^2 + (Y2 - Y1)^2)\)

Using the above points, the distance (D) would be:

D = \(√((4 - 2)^2 + (8 - 3)^2)√ = \(√(4+25) = \(√29\)√

The distance between the two points is the square root of 29.

Practicing these formulas enhances your problem-solving skills and helps in many areas of mathematics, including geometry and algebra.

Prepare 350g of a 2% lidocaine cream using a 1% lidocaine cream a 5% lidocaine cream

Answers

a)    1% lidocaine -x g,      0.01x pure lidocaine 
        5% lidocaine -y g,      0.05y pure lidocaine
(1)0.01x+0.05y=350*0.02
0.01x  g we get from1% lidocoine and 0.05y g we get from 5% lidocoine

(2) x+y=350 
x g is mass 1% lidocoine, we combine it with y g 5%,
so we get x+y, and we need 350g,
so x+y should be equal 350, x+y=350

we get system of 2 equations that we need to solve to find x and y

(1)0.01x+0.05y=350*0.02
(2) x+y=350

we can solve it by substitution, find x from (2) equation
x=350-y, substitute it into  (1)
instead of x we put (350-y)
0.01(350-y)+0.05y=7
3.5-0.01y+0.05y=7
0.04y =3.5
y=87.5g 5% lidocaine

b)x=350-87.5=262.5 g 1% lidocaine
c) 350g =350000 mg


------------------------------------------------------------------
Define x and y:
------------------------------------------------------------------
Let x be the amount of 1% lidocaine needed.
Let y be the amount of 5% lidocaine needed.

------------------------------------------------------------------
Construct Equations:
------------------------------------------------------------------
x + y = 350

0.01x + 0.05y = 0.02 x 350
0.01x + 0.05y = 7

------------------------------------------------------------------
Solve x and y:
------------------------------------------------------------------
x + y = 350             ------------- (Equation 1)
0.01x + 0.05y = 7   ------------- (Equation 2)

------------------------------------------------------------------
From equation 1:
------------------------------------------------------------------
x + y = 350
x = 350 - y 

------------------------------------------------------------------
Substitute x = 350 - y into equation 2:
------------------------------------------------------------------
0.01(350 - y) + 0.05y = 7
3.5 - 0.01y + 0.05y = 7
3.5 + 0.04y = 7
0.04y = 7 - 3.5
0.04y = 3.5
y = 87.5

------------------------------------------------------------------
Substitute y = 87.5 into equation 1:
------------------------------------------------------------------
x + y = 350
x + 87.5 = 350
x = 350 - 87.5
x = 262.5

------------------------------------------------------------------
Find x and y:
------------------------------------------------------------------
x = 262.6g (5% lidocaine cream)
y = 87.5g   (1% lidocaine cream)

------------------------------------------------------------------
Convert 350g to milligram:
------------------------------------------------------------------
350g = 350 x 1000 mg
350g = 350 000mg

------------------------------------------------------------------
Answer:
(a) Amount of 5% lidocaine needed = 87.5g
(b) Amount of 1% lidocaine needed = 262.g
(c) 350g = 350 000mg

What is the area of a triangle that has a base of 15 1/4 in and a height of 18 in?

Answers

the area of a triangle = 1/2 base * height (basically half of a rectangle)

so 1/2 * 18 * 15.25 = 9*15.25 = 137.25

don't forget units so the answer is 137.25 inches squared

The area of the triangle is half the product of its base and height. The area of the triangle is 137.25 in².

What is the area of the triangle?

The area of the triangle is half the product of its base and height. It is given by the formula,

[tex]\rm \text{Area of triangle} = \dfrac{1}{2} \times base \times height[/tex]

As it is given that the base of the triangle is 15¹/₄ inches, while the height of the triangle is 18 inches. Therefore, the area of the triangle is,

[tex]\rm \text{Area of triangle} = \dfrac{1}{2} \times base \times height[/tex]

                         [tex]= \dfrac{1}{2} \times 15(1/4)\times 18\\\\\\ = \dfrac{1}{2} \times \dfrac{(15\times 4)+1}{4} \times 18\\\\\\= \dfrac{1}{2} \times \dfrac{61}{4} \times 18\\\\\\=137.25\rm\ in^2[/tex]

Hence, the area of the triangle is 137.25 in².

Answers

Answer: [tex]P(x) = 50,000(1.12)^x[/tex]

Explanation: Let [tex]P(x)[/tex] be the population after x years. Since 50,000 is the initial population, P(0) = 50,000. Moreover, since the population increases 12% per year, 

[tex]P(x) = P(x - 1) + 12\% (P(x - 1)) \\ = P(x - 1) + 0.12(P(x - 1)) \\ \boxed{P(x) = 1.12(P(x - 1))}[/tex]

Using the preceding equation:

[tex]P(1) = 1.12(P(0)) = 50,000(1.12) \\ P(2) = 1.12(P(1)) = 1.12(50,000(1.12)) = 50,000(1.12)^2 \\ P(3) = 1.12(P(2)) = 1.12(50,000(1.12)^2) = 50,000(1.12)^3 \\. \\. \\. \\P(x) = 1.12(P(x-1)) = 1.12(50,000(1.12)^{x-1}) = 50,000(1.12)^x \\\boxed{P(x) = 50,000(1.12)^x}[/tex]

Choose the right answer. Two hundred fifty tickets are sold at a church fund raiser. If Sarah buys 15 tickets, the probability that she will win the prize quilt is .

Answers

There is a 3/50 or 6% chance that sara will win the prize. 

Answer:

Her probability to win the prize quilt is 0.06, or she has a 6% probability of winning it.

Step-by-step explanation:

In statistics, a probability of 100% is represented with a 1. In this case, if Sarah would have bought the 250 tickets, she would have a probability of 1 to win the prize, as

[tex]\frac{250}{250}=1[/tex]

then, if this expression is multiplied by 100, we could say that the precentage of probability would have been 100%...

But Sarah didn't buy the 250 tickets, instead she bought 15, therefore

[tex]\frac{15}{250}=\frac{3}{50}=0.06[/tex]

which means that the probability of her winning the prize quilt is 0.06, or, if multiplied by 100, she has a 6% probability of winning the prize quilt.

15.7/12 = 1.308333333
cos(1.308333333)
0.999739299

The correct answer is [tex]\frac{1}{2}[/tex].

To find the exact value of [tex]\cos(5\pi/12)[/tex] using a half-angle formula, we can follow these steps:

[tex]\cos(2\theta) = 2\cos^2(\theta/2) - 1[/tex]

Substituting [tex]\theta = 5\pi/6[/tex], we get:

[tex]\cos(5\pi/3) = 2\cos^2(5\pi/12) - 1[/tex]

[tex]\cos^2(5\pi/12) = \frac{\cos(5\pi/3) + 1}{2}[/tex]

[tex]\cos(5\pi/3) = \cos(\pi/3 + \pi) = -\cos(\pi/3)[/tex]

[tex]\cos(\pi/3) = \frac{1}{2}[/tex]

[tex]\cos(5\pi/3) = -\frac{1}{2}[/tex]

[tex]\cos^2(5\pi/12) = \frac{-\frac{1}{2} + 1}{2} = \frac{1}{4}[/tex]

[tex]\cos(5\pi/12) = \pm\sqrt{\frac{1}{4}} = \pm\frac{1}{2}[/tex]

Since cosine is an even function, we take the positive value.

[tex]\cos(5\pi/12) = \frac{1}{2}[/tex]

Therefore, the exact value of [tex]\cos(5\pi/12)$ is $\frac{1}{2}[/tex].

For her cell phone plan Heather pays $30 per month plus 0.05 protects she wants to keep her bill under $60 per month with any quality represents the number of texts T Heather can't spend each month while staying within her budget

Answers

Hi there!

Let the number of texts be represented by T.
The we get the following function of total cost:
Total cost = 30 + 0.05T.

Since Heather wants her bill to be under $60, the total cost must be smaller than 60. We get the following

30 + 0.05T < 60
Subtract 30 from both sides.

0.05T < 30
Divide by 0.05

T < 600. Therefore Heather can send a maximum of 600 texts (and then she pays a bill of $60)

The sum of the length and width ratio units is 6+2 = 8. Since this stands for 24 cm, each ratio unit stands for 3 cm. The actual dimensions are
  18 cm : 6 cm : 21 cm

The surface area (S) is given in terms of length (L), width (W), and height (H) by
  S = 2(LW +H(L+W))
  = 2((18 cm)*(6 cm) +(21 cm)*(18 cm +6 cm))
  = 2(108 cm² +(21 cm)*(24 cm))
  = 1224 cm²

The surface area of the box of cereal is 1224 cm².

Using an algebraic rule, describe a translation 2 units to the left.

Answers

Answer:
point (x,y) translated 2 units to the left will give the point (x-2,y)
(x,y) = (x-2,y)

Explanation:
We will apply the translation on a given point.
Suppose that we have a point with coordinates (x,y).
We want to translate this point 2 units to the left. This means that we will move this point 2 units to the left.
Doing this, we will find that:
the x-value of the coordinate is decreased by 2
the y-value of the coordinate did not change as no translation occurred in the vertical axis.

Therefore:
a point (x,y) can be translated two units to the left to be (x-2 , y)

the width of a rectangle is X and the length is twice he width. if the area of the rectangle is 162, what is X?

Answers

Final answer:

To find the value of X in a rectangle with width X and length 2X, we can use the area formula. By solving the equation, we find X = 9, making the width of the rectangle 9 units.

Explanation:

To find the value of X, we need to use the given information about the length and width of the rectangle. Let's assume the width of the rectangle is X. Since the length is double the width, it is 2X. The area of the rectangle is given as 162, so we can set up the equation:

Width × Length = Area

X × 2X = 162

Simplifying the equation, we get:

2X^2 = 162

Dividing both sides by 2, we have:

X^2 = 81

Taking the square root of both sides, we find:

X = ±9

Since the width cannot be negative, the value of X is 9. Therefore, the width of the rectangle is 9 units.
