Answer:

50% of 30 is 15. 25% of 40 is 10. So, the product of 50% of 30 and 25% of 40 is 150.

Here's the calculation:

```

(50/100) * 30 * (25/100) * 40 = 150

```

Step-by-step explanation:

The power to which a number or expression is raised is called the exponent.

1. An exponent is a mathematical notation that represents the power to which a number or expression is raised. It is written as a superscript number or variable placed above and to the right of the base number or expression.

2. The base number or expression is the number or expression that is being multiplied repeatedly by itself, raised to the power of the exponent.

3. The exponent tells us how many times the base number or expression should be multiplied by itself. For example, in the expression \(2^3\), the base is 2 and the exponent is 3. This means that 2 should be multiplied by itself three times: 2 * 2 * 2 = 8.

4. The exponent can be a positive whole number, a negative number, zero, or a fraction. Each of these cases has different interpretations:

  - Positive exponent: Indicates repeated multiplication. For example, \(2^4\)means 2 multiplied by itself four times.

  - Negative exponent: Indicates the reciprocal of the base raised to the positive exponent. For example, \(2^{-3\) means 1 divided by \(2^3\).

  - Zero exponent: Always equals 1. For example, \(2^0\) = 1.

  - Fractional exponent: Represents a root. For example, \(4^{(1/2)\)represents the square root of 4.

5. Exponents follow certain mathematical properties, such as the product rule \((a^m * a^n = a^{(m+n)})\), the quotient rule \((a^m / a^n = a^{(m-n)})\), and the power rule \(((a^m)^n = a^{(m*n)})\).

Remember to use these rules and definitions to correctly interpret and evaluate expressions involving exponents.

Using the given information, in the right triangle ABC with C = 90°, A = 33.3°, a = 43.7 inches, we can solve for the missing parts: b ≈ 76.6 inches and B ≈ 56.7°.

Given the right triangle ABC with C = 90°, A = 29°, c = 26 m, and B = 3°, we need to solve for the missing parts.

To find the missing side lengths and angles, we can use trigonometric functions such as sine, cosine, and tangent.

To find side a:

We can use the sine function: sin(A) = a / c

Substituting the known values, we have: sin(29°) = a / 26

Solving for a, we get: a ≈ 26 \(\times\) sin(29°)

Calculating this value, we find: a ≈ 12.84 m (rounded to two decimal places).

To find side b:

Using the Pythagorean theorem: \(a^2 + b^2 = c^2\)

Substituting the known values, we have: \((12.84)^2 + b^2 = (26)^2\)

Simplifying and solving for b, we get: b ≈ \(\sqrt{((26)^2 - (12.84)^2)}\)

Calculating this value, we find: b ≈ 22.61 m (rounded to two decimal places).

To find angle B:

We can use the sine function: sin(B) = b / c

Substituting the known values, we have: sin(B) = 22.61 / 26

Solving for B, we find: B ≈ arcsin(22.61 / 26)

Calculating this value, we find: B ≈ 57.6° (rounded to one decimal place).

Therefore, the missing parts of the triangle are:

a ≈ 12.84 m (rounded to two decimal places),

b ≈ 22.61 m (rounded to two decimal places),

and B ≈ 57.6° (rounded to one decimal place).

Jackie pays $130 monthly for her group health insurance.

To find out how much Jackie pays for her group health insurance monthly, we need to calculate 40% of the annual cost. Given that the annual cost is $3,900 and her company pays 40% of that, we can calculate the amount Jackie pays.

First, we find the company's contribution by multiplying the annual cost by 40%: $3,900 × 0.40 = $1,560. This is the amount the company pays towards Jackie's health insurance.

To determine Jackie's monthly payment, we divide her annual payment by 12 (months in a year) since she pays monthly. So, Jackie's monthly payment is $1,560 ÷ 12 = $130.

Therefore, Jackie pays $130 per month for her group health insurance. This calculation takes into account the company's contribution of 40% of the annual cost, resulting in an affordable monthly payment for Jackie.

The probability that two children selected at random from Mrs. Attaway's first-grade class are girls and one is a boy is 0.120.

To find the probability that two children selected at random from Mrs. Attaway's class are girls and one is a boy, we need to calculate the number of favorable outcomes (selecting two girls and one boy) and divide it by the total number of possible outcomes.

The total number of children in the class is 5 girls + 16 boys = 21 children.

To calculate the probability, we need to determine the number of ways to select two girls from the five available girls and one boy from the 16 available boys. This can be done using combinations.

The number of ways to select two girls from five is given by the combination formula:

C(5, 2) = 5! / (2! * (5 - 2)!)

= 5! / (2! * 3!)

= (5 * 4) / (2 * 1)

= 10

Similarly, the number of ways to select one boy from 16 is given by the combination formula:

C(16, 1) = 16

The total number of favorable outcomes is the product of these two combinations: 10 * 16 = 160.

Now, let's calculate the total number of possible outcomes when selecting three children from the class:

C(21, 3) = 21! / (3! * (21 - 3)!)

= 21! / (3! * 18!)

= (21 * 20 * 19) / (3 * 2 * 1)

= 1330

Finally, we can calculate the probability by dividing the number of favorable outcomes by the total number of possible outcomes:

Probability = favorable outcomes / total outcomes

= 160 / 1330

≈ 0.120 (rounded to three decimal places)

Therefore, the probability that two children selected at random from Mrs. Attaway's first-grade class are girls and one is a boy is 0.120.

The volume of the cylinder is approximately 960 cubic centimeters.

To find the volume of the cylinder, we need to use the formula V = πr^2h, where r is the radius of the cylinder, h is its height, and π is the mathematical constant approximately equal to 3.14.

Given that the diameter of the cylinder is 8 cm, we can find the radius by dividing the diameter by 2:

radius (r) = diameter / 2

r = 8 cm / 2

r = 4 cm

We are also given that the height of the cylinder is 20 cm.

Substituting the values for r and h into the formula, we get:

V = πr^2h

V = π(4 cm)^2(20 cm)

V = π(16 cm^2)(20 cm)

V = 320π cm^3

Using the value of π as 3, we can approximate the volume as:

V ≈ 320(3)

V ≈ 960 cm^3

When the value of π is rounded to 3 and the radius is 4 cm and the height is 20 cm.

To show that the given equations represent trigonometric identity statements, we will simplify each equation and demonstrate that both sides of the equation are equal.

Starting with sec²θ(1 - cos²θ):

Using the Pythagorean identity sin²θ + cos²θ = 1, we can rewrite sec²θ as 1 + tan²θ. Substituting this into the equation, we get:

(1 + tan²θ)(1 - cos²θ)

= 1 - cos²θ + tan²θ - cos²θtan²θ

= 1 - cos²θ(1 - tan²θ)

= sin²θ

Thus, the equation simplifies to sin²θ, which is a trigonometric identity.

For cosx(secx - cosx) = sin²x:

Using the reciprocal identities secx = 1/cosx and tanx = sinx/cosx, we can rewrite the equation as:

cosx(1/cosx - cosx)

= cosx/cosx - cos²x

= 1 - cos²x

= sin²x

Hence, the equation simplifies to sin²x, which is a trigonometric identity.

Considering cosθ + sinθtanθ = secθ:

Dividing both sides of the equation by cosθ, we obtain:

1 + sinθ/cosθ = 1/cosθ

Using the identity tanθ = sinθ/cosθ, the equation becomes:

1 + tanθ = secθ

This is a well-known trigonometric identity, where the left side is equal to the reciprocal of the right side.

Simplifying (1 - cos∝)(cosec∝ + cot∝):

Expanding the expression, we have:

cosec∝ - cos∝cosec∝ + cot∝ - cos∝cot∝

= cot∝ - cos∝cot∝ + cosec∝ - cos∝cosec∝

= cot∝(1 - cos∝) + cosec∝(1 - cos∝)

= cot∝tan∝ + cosec∝sec∝

= 1 + 1

= 2

Thus, the equation simplifies to 2, which is a constant value.

In summary, we have analytically shown that the given equations represent trigonometric identity statements by simplifying each equation and demonstrating that both sides are equal.

The car's speed after the given amout of time is 19.8 m/s²

The rate at which an object's velocity with respect to time changes is referred to as acceleration in mechanics. They are vector quantities, accelerations. The direction of the net force acting on an object determines the direction of its acceleration. A point or object going straight ahead is accelerated when it accelerates or decelerates. Any alteration in an object's velocity could take the form of a change in direction of motion or a speed increase or reduction. The moon orbiting the earth, an apple falling to the ground, and a car stopped at a stop sign are a few instances of acceleration.

Average Acceleration =Change in Velocity/ Time Taken

So Change in Velocity is 10-x m/s

Time taken is 7.25 s

Given accelaration 4.11 m/s²

Putting the values we get,

4.11 = (10-x)/7.25

To find the derivative of p(x) = (5x³ + 3x - 3)(2x² + 3x + 4) with respect to x, we apply the product rule of differentiation.  By applying this rule and simplifying the expression, we can find the derivative of p(x).

To find the derivative of p(x) = (5x³ + 3x - 3)(2x² + 3x + 4), we apply the product rule:

p'(x) = (5x³ + 3x - 3)(d/dx)(2x² + 3x + 4) + (d/dx)(5x³ + 3x - 3)(2x² + 3x + 4)

To find the derivative of each individual term, we can use the power rule and the sum rule of differentiation.

Taking the derivatives, we have:

p'(x) = (5x³ + 3x - 3)(4x + 6) + (5(3x²) + 3)(2x² + 3x + 4)

Simplifying this expression, we obtain:

p'(x) = 50x⁴ + 60x³ + 78x² + 6
