The correct answer is option d) \( 1+\tan x \), since \( \sec x=1+\tan x \).

The correct answer for the given expression \( \tan x \cdot \sin x+\cos x=? \) is option d) \( 1+\tan x \).

Step-by-step explanation:

We can start by using the identity \( \tan x = \frac{\sin x}{\cos x} \) to rewrite the expression:
\( \frac{\sin x}{\cos x} \cdot \sin x+\cos x=? \)

Next, we can simplify the expression by multiplying the numerator and denominator by \( \cos x \):
\( \frac{\sin^2 x+\cos^2 x}{\cos x}=? \)

Now, we can use the identity \( \sin^2 x+\cos^2 x=1 \) to further simplify the expression:
\( \frac{1}{\cos x}=? \)

Finally, we can use the identity \( \frac{1}{\cos x}=\sec x \) to rewrite the expression in terms of \( \sec x \):
\( \sec x=? \)

Therefore, the correct answer is option d) \( 1+\tan x \), since \( \sec x=1+\tan x \).

It will take 18 years for the Type A and Type B trees to be the same height.

A location in the centre of a line connecting two places is referred to as the midpoint. The midpoint of a line is located between the two reference points, which are its ends. The line that connects these two places is split in half equally at the halfway. In addition, the halfway is reached if a line is drawn to divide the line that connects these two places.

Let us suppose the number of years = y.

The height of the tree of type A is thus,

5 feet + (4 inches/year)(y)

= 5 + 4/12 y feet

= 5 + 1/3 y feet

For the type B:

2 feet + (10 inches/year)(y years)

= 2 + 10/12 y feet

= 2 + 5/6 y feet

To get the height of the two trees as equal we have:

5 + 1/3 y = 2 + 5/6 y

3 + 1/3 y = 5/6 y

3 = 1/6 y

18 = y

Hence, it will take 18 years for the Type A and Type B trees to be the same height.

(b) 12¹¹

(c) 4²⁴

(d) 64¹¹.

The value of a is 576.43, when a varies directly as b and inversely as the square of c.

Given that a varies directly as b and inversely as the square of c, we can write the equation as:

a = k * (b/c²)

Where k is the constant of proportionality.

We are given that a=113 when b=7 and c=8, so we can plug these values into the equation and solve for k:

113 = k * (7/8²)

113 = k * (7/64)

k = 113 * (64/7)

k = 1036.57

Now that we know the value of k, we can plug in the new values of b and c to find a:

a = 1036.57 * (5/3²)

a = 1036.57 * (5/9)

a = 576.43

Therefore, when b=5 and c=3, a=576.43.

Answer:

chatGPT

Step-by-step explanation:

Let's denote the speed of each car as v, and the distance that Car A travels as d. Then we can set up two equations based on the information given:

d = v * (12/60) (since Car A reaches its destination in 12 minutes)

d + 4 = v * (18/60) (since Car B travels 4 miles farther than Car A and reaches its destination in 18 minutes)

Simplifying the equations by multiplying both sides by 60 (to convert the minutes to hours) and canceling out v, we get:

12v = 60d

18v = 60d + 240

Subtracting the first equation from the second, we get:

6v = 240

Therefore:

v = 240/6 = 40

So the cars travel at a speed of 40 miles per hour.

The value of a when b=4 and c=4 is 72.70. Rounded to two decimal places, the answer is 72.70.

The variable a is jointly proportional to the cube of b and the square of c. This means that the relationship between a, b, and c can be expressed as: a = k * b^3 * c^2, where k is a constant of proportionality.

When a=433, b=5, and c=7, we can plug these values into the equation to find the value of k:
433 = k * 5^3 * 7^2
433 = k * 125 * 49
433 = k * 6125
k = 433/6125
k = 0.07069

Now, we can use this value of k to find the value of a when b=4 and c=4:
a = k * b^3 * c^2
a = 0.07069 * 4^3 * 4^2
a = 0.07069 * 64 * 16
a = 72.70

Therefore, the value of a when b=4 and c=4 is 72.70. Rounded to two decimal places is 72.70.

We denote division by '÷' this symbol.

Destiny combined a total of 8.27 + 6.65 = 14.92 liters of paint to make purple paint.

She poured this paint equally into 2 containers, which means each container has half of the total amount of paint:

= 14.92 / 2

= 7.46 liters

However, Destiny also had 1.56 liters of paint left over that she didn't use.

To divide the remaining paint equally between the two containers, each container gets half of the remaining paint:

No, the point (1,4) is not a solution of the set of linear inequalities y > 5x + 1 and y ≥ (1/2)x - 1 since the point does not satisfy both inequalities.

To determine if a point is a solution, we can substitute the x and y values of the point into the inequalities and see if they are true.

For the first inequality, y > 5x + 1:
4 > 5(1) + 1
4 > 6
This is not true, since 4 is not greater than 6. So the point (1,4) is not a solution for the first inequality.

For the second inequality, y ≥ (1/2)x - 1:
4 ≥ (1/2)(1) - 1
4 ≥ 0.5 - 1

4 ≥ -0.5

This is true, since 4 is greater than -0.5.

Of these 12 individuals: Expected number of survivors ≈ 4.

If the chance of survival for a person who tests positive for the disease is 30%, and 12 people have been admitted and tested positive for the disease, then the expected number of survivors is 30% of 12, which is 3.6.

However, since it is not possible for 0.6 of a person to survive, we can round this number to the nearest whole number, which is 4.

Therefore, we can expect that 4 out of the 12 people who tested positive for the disease will survive. This can be written as:

Expected number of survivors = (Chance of survival) × (Number of people who tested positive) = (0.30) × (12) = 3.6 ≈ 4

For the given function f(x) = (x - 4)² - 3, the following statements are correct -

B: relative minimum at (4,-3).

C: decreasing interval from (-∞, 4).

E: increasing interval is (4, ∞).

What is a function?

In mathematics, a function is a unique arrangement of the inputs (also referred to as the domain) and their outputs (sometimes referred to as the codomain), where each input has exactly one output and the output can be linked to its input.

To find the relative maximum and minimum of the function, we need to find its critical points by setting the derivative of the function equal to zero -

f(x) = (x - 4)² - 3

f'(x) = 2(x - 4)

2(x - 4) = 0

x = 4

So, the only critical point of the function is x = 4.

Plug in the value of x = 4 in the equation -

(4 - 4)² - 3

0 - 3

-3

Since f''(4) is positive, the critical point at x = 4 is a relative minimum.

Therefore, the function has a relative minimum at (4, -3).

To find the increasing and decreasing intervals, we can look at the sign of the first derivative -

f'(x) = 2(x - 4)

For x < 4, f'(x) is negative, meaning that f(x) is decreasing on the interval (-∞, 4).

For x > 4, f'(x) is positive, meaning that f(x) is increasing on the interval (4, ∞).

Therefore, the decreasing interval is (-∞, 4), and the increasing interval is (4, ∞).

Answer:

A perfect square trinomial is a trinomial expression of the form:

a^2 + 2ab + b^2

Where a and b are constants, it can also be written as (a + b)^2.

To identify a perfect square trinomial, we can check if the first and last terms are perfect squares and if the middle term is twice the product of the square roots of the first and last terms.

For example, let's consider the expression:

x^2 + 4x + 4

The first term is x^2, which is a perfect square. The last term is 4, which is also a perfect square. The middle term is 4x, twice the product of the square roots of x^2 and 4 (i.e., 2x). Therefore, this expression is a perfect square trinomial:

x^2 + 4x + 4 = (x + 2)^2

To simplify this expression, we can use the fact that (a + b)^2 = a^2 + 2ab + b^2:

(x + 2)^2 = x^2 + 2(x)(2) + 2^2 = x^2 + 4x + 4

Therefore, the perfect square trinomial x^2 + 4x + 4 is equivalent to (x + 2)^2.

We have the following response after answering the given question: To interest the nearest penny, the balance in the account after 12 years is thus $17,821.76.

To calculate simple interest, divide the principal by the interest rate, the duration, and other variables. The marketing formula is simple return = capital + interest + hours. The easiest way to calculate interest is with this approach. The most popular method for calculating interest is as a percentage of the principal amount. For instance, if he borrows $100 from a friend and agrees to pay it back at 5% interest, he will only pay his portion of the 100% interest. $100 (0.05) = $5. Interest must be paid when you borrow money and must be added to any loans you make. The yearly percentage of the loan amount is frequently used to calculate interest. This percentage represents the loan's interest rate.

Continuously compounded interest is calculated as follows:

[tex]V = Pe^(rt) (rt)[/tex]

where: V = the investment's final value

P is the original investment's principle.

r equals the yearly interest rate (as a decimal)

t is the duration of the investment, in years.

P = $8290, r = 0.06 (6% as a decimal), and t = 12 years in this example.

So, [tex]V = 8290e^(0.06*12) = $17,821.76[/tex]

To the nearest penny, the balance in the account after 12 years is thus $17,821.76.
