What is 4.5-4x evaluated

Answer:

16 - 25z²

Step-by-step explanation:

(4 - 5z)(4 + 5z)

each term in the second factor is multiplied by each term in the first factor, that is

4(4 + 5z) - 5z(4 + 5z) ← distribute parenthesis

= 16 + 20z - 20z - 25z² ← collect like terms

= 16 - 25z²

Answer:

16-25z

Step-by-step explanation:

you will use the first term 4 to multiply the first which is (4+5z) then after that you will use the second term which is -5z to multiply the same (4+5z) to give you 16+20z-20z-25z then you will also simplify to give you 16-25z

Rounding to the nearest hundredth, the density of the candle is 22.46 grams per cubic inch.

The density of the candle can be found by dividing the mass by the volume of the candle.

The volume of a cylindrical candle can be found using the formula V = πr^2h,

where V is the volume, r is the radius, and h is the height.

First, we need to find the radius of the candle.

The diameter is 3 inches, so the radius is 1.5 inches.

Next, we can plug in the values for r and h into the formula for the volume of a cylinder:

V = π(1.5)^2(4) = 9π

Now, we can divide the mass of the candle by the volume to find the density:

Density = 200 grams / 9π

Density= 22.46 grams per cubic inch

The value of each investment scenario based on the given interest compounded will be:

Let's discuss each scenario we have.

The value of Rod's annuity after 20 years will be $30,904.95. This is calculated by using the formula A = P((1+r/n)^(nt)), where P is the payment, r is the annual interest rate (7.88%), n is the number of times compounded per year (quarterly, or 4), and t is the number of years (20).

The value of Bubba's investment after 25 years will be $41,438.55. This is calculated by using the formula A = P((1+r/n)^(nt)), where P is the payment, r is the annual interest rate (7.26%), n is the number of times compounded per year (monthly, or 12), and t is the number of years (25).

The equivalent APY for the account at Crab Key Bank with an annual interest rate of 5.15% compounded quarterly is 5.25%. This is calculated by using the formula APY = (1+r/n)^n - 1, where r is the annual interest rate (5.15%), and n is the number of times compounded per year (quarterly, or 4).

The difference between an investment earning 8.75% annual interest compounded quarterly and one earning 8.7% compounded monthly is the number of times the interest is compounded each year. An investment earning 8.75% compounded quarterly has an interest rate of 8.75% that is compounded four times per year, while an investment earning 8.7% compounded monthly has an interest rate of 8.7% that is compounded twelve times per year.

The missing measures of the pentagon are a = 18.4, c = 61.2, d = 75, and x = 22.08.

Let's label the sides of the first pentagon as a, 20, c, 30, and x, and the sides of the second pentagon as 46, 50, d, 102, and 24.

Since both pentagons have the same shape, we know that the corresponding sides are proportional. This means we can set up the following equations:

a/46 = 20/50 = c/d = 30/102 = x/24

Solving for the missing variables:

a = 46(20)/50 = 18.4

c = 30(102)/50 = 61.2

d = 50(30)/20 = 75

You should recall that Probability is the chance that a given event will occur; the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes;

The conditional probability P(A|B) is calculated using:

P(A/B)

P(A/B) = P( A and B) / P(B)

P(A/B) = (18/26 * 8/26)/ 8/26

P(A/B) = (0.69 * 0.31)/ 0.31

P(A/B) = 0.69

P(A/B) = 69/100

b)  Using the same formula

P(B/A) = P( B and A) / P(A)

P(A/B) = (8/26 * 18/26) / 18/26

  B-----------C

          y

where A and B are the entrances of the tunnel, C is the point in the middle of the tunnel that we want to find, and θ, x, and y are the angles and distances given in the problem. We want to find the length of AC.

Using trigonometry, we can find the distances BC and AB: tan(57°) = x / y  =>  x = y * tan(57°)

tan(14°) = x / (y + 212)  =>  x = (y + 212) * tan(14°)

Setting these two expressions for x equal, we get: y * tan(57°) = (y + 212) * tan(14°)

Solving for y, we get: y = 212 / (tan(57°) / tan(14°) - 1) ≈ 286.5 meters

Now we can use the law of sines to find the length of AC: sin(θ) / AC = sin(14°) / BC = sin(57°) / AB

Solving for AC, we get: AC = AB * sin(θ) / sin(57°) ≈ 368.6 meters

Therefore, the length of the entire tunnel is approximately 2 * AC = 737.2 meters. Rounded to the nearest tenth, the answer is 737.2 meters.

The volume of the pyramid is found to be approximately 18.046 cubic units.

To find the volume (V) of the pyramid, we need to use the formula for the volume of a pyramid, which is V = (1/3) × Base Area × Height.

In this case, the base is a square, so we can find the area of the base by squaring one of the sides: Base Area = AB² = 4.5² = 20.25.

To find the height of the pyramid, we need to use the Pythagorean theorem to find the slant height, and then use that to find the height. Let h be the height of the pyramid and s be the slant height. We have:

s² = AB² + (1/2) DC² (Pythagorean theorem for triangle ABC)

s² = 4.5² + (1/2) DC²

Since all edges of the pyramid are congruent, we have DC = AB = 4.5. Substituting this into the equation above, we get:

s² = 4.5² + (1/2) × 4.5²

s² = 30.375

s ≈ 5.509

To find the height h, we can use the Pythagorean theorem again for triangle ABD:

h² = AB² - (1/4) s²

h² = 4.5² - (1/4) × 30.375

h² ≈ 7.875

h ≈ 2.807

Now that we have found the base area and the height, we can use the formula for the volume of a pyramid to find V:

V = (1/3) × Base Area × Height

V = (1/3) × 20.25 × 2.807

V ≈ 18.046

Therefore, the volume of the pyramid is approximately 18.046 cubic units.

Answer: The acceleration of the bus can be calculated using the formula:

a = (v2 - v1) / t

where:

a = acceleration

v2 = final velocity = 306 m/s

v1 = initial velocity = 126 m/s

t = time = 3 seconds

Substituting the given values into the formula, we get:

a = (306 m/s - 126 m/s) / 3 s

a = 180 m/s / 3 s

a = 60 m/s^2

Therefore, the acceleration of the bus is 60 m/s^2.

The area of the blue region is 28.93 cm²

To find the area of the blue region, we need to subtract the area of the four circle from the area of the rectangle.

Since the diameter of the circle is 3cm. The radius (r) = 3/2 = 1.5 cm.

Length of the rectangle (L) = 4 * diameter of circle (we have 4 circles)

Length of the rectangle = 4 * 3 = 12 cm

Width of the rectangle (W) = diameter of circle = 3 cm

Area of rectangle = L * W

Area of rectangle = 12 * 3 = 36 cm²  

Area of circle = πr²

Area of circle = π * 1.5² = 2.25π cm²  

Area of the blue region = Area of rectangle - Area of circle

Area of the blue region = 36 - 2.25π

Area of the blue region = 36 - (2.25* 22/7)

If a rectangle door of a dollhouse has a height of 7 centimeters and a width of 3 centimeters, the perimeter of the door in the scale drawing is 70 centimeters.

To find the perimeter of the door in the scale drawing, we first need to determine the dimensions of the door in the scale drawing. To do this, we need to multiply the actual dimensions of the door by the scale factor of 3.5.

The height of the door in the scale drawing would be 7 cm x 3.5 = 24.5 cm, and the width would be 3 cm x 3.5 = 10.5 cm.

The perimeter of the door in the scale drawing can be calculated by adding up the lengths of all four sides. The two vertical sides have a length of 24.5 cm, and the two horizontal sides have a length of 10.5 cm. Therefore, the perimeter of the door in the scale drawing is:

P = 2(24.5 cm) + 2(10.5 cm) = 49 cm + 21 cm = 70 cm

Note that the scale drawing is a proportional representation of the actual door, where all corresponding dimensions are multiplied by the same factor of 3.5.

The given statement "B ∩ C = C ∩ B" is true, since the intersection of two sets is a commutative operation, which means the order in which we list the sets does not matter.

To find the intersection of two sets, we need to identify the elements that are common to both sets. In this case, we can list the elements of each set and identify their common elements:

B = {a, b, c}

C = {a, c, e, g}

B ∩ C = {a, c}

C ∩ B = {a, c}

As we can see, the intersection of B and C is {a, c}, and the intersection of C and B is also {a, c}. The order in which we list the sets does not affect the result of the intersection operation, since the elements of both sets are the same.

Therefore, we can conclude that B ∩ C = C ∩ B is true, and that the intersection of B and C contains the same elements regardless of the order in which we list the sets.

In summary, the intersection of two sets is a commutative operation, which means that the order in which we list the sets does not affect the result. Therefore, B ∩ C = C ∩ B is true, and the intersection of B and C contains the same elements regardless of the order in which we list the sets.

The answer of the given question based on the Voltage drop the answer is , the voltage dropped across R3 is 277.11 V.

Ohm's law is  fundamental principle in electrical engineering and physics that describes  relationship between voltage, current, and resistance in  electrical circuit. It states that current through conductor between two points is directly proportional to voltage across  two points, and inversely proportional to resistance between them.

To determine the voltage dropped across R3, we need to use Ohm's law and Kirchhoff's circuit laws. First, we can calculate the total resistance in the circuit:

Rtotal = R1 + R2 || R3

R2 || R3 = (R2 * R3) / (R2 + R3) (parallel resistance formula)

Rtotal = R1 + (R2 || R3)

Rtotal = 152 + ((18 * 362) / (18 + 362))

Rtotal = 149.89 Ω (rounded to 2 decimal places)

Next, we can use Ohm's law to calculate the current flowing through the circuit:

I = ET / Rtotal

I = 120 / 149.89

I = 0.8004 A (rounded to 4 decimal places)

Finally, we can use Kirchhoff's voltage law to determine the voltage dropped across R3:

ET = IR1 + IR2 || IR3 + IR3

ET = I(R1 + R2 || R3) + IR3

ET - I(R1 + R2 || R3) = IR3

R3 = (ET - I(R1 + R2 || R3)) / I

R3 = (120 - (0.8004 * (152 + ((18 * 362) / (18 + 362))))) / 0.8004

R3 = 277.11 V (rounded to 2 decimal places)

Therefore, the voltage dropped across R3 is 277.11 V.

The expressions after factorizing are;

1. (x+4)(x - 6). Option A

2. (x+ 5)(x - 6). Option A

3.  (x - 8)(x - 9). Option A

From the information given, we have the following quadratic equations;

To factorize the expressions, we need to first, multiply the coefficient of x²   by the constant value.

Then, find the pair factors of the product whose sum would give the coefficient of x variable and substitute the values.

For the first expression;

x² - 2x - 24

x² - 6x + 4x - 24

group in pairs

(x² - 6x) + (4x -24)

factorize

x(x - 6) + 4(x - 6): (x+4)(x - 6)

x² - x - 30

x² - 6x + 5x - 30

group in pairs and factorize

x(x - 6) + 5(x - 6): (x+ 5)(x - 6)

x² - 17x + 72

x² - 9x - 8x + 72

Group in pairs and factorize

x(x - 9) - 8(x - 9): (x - 8)(x - 9)
