Answer:

[tex]\displaystyle 18,28 ≈ x[/tex]

Step-by-step explanation:

[tex]\displaystyle \frac{x}{11} = csc\:37 \hookrightarrow 11csc\:37 = x \hookrightarrow 18,278041552... = x \\ \\ 18,28 \approx x[/tex]

OR

[tex]\displaystyle \frac{11}{x} = sin\:37 \hookrightarrow xsin\:37 = 11 \hookrightarrow \frac{11}{sin\:37} = x \hookrightarrow 18,278041552... = x \\ \\ 18,28 \approx x[/tex]

The claim supported by the confidence interval is as follows:

The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.

The 95% confidence interval for the difference(southern - northern) is given by:

(7.1, 8.1)

Since the entire confidence interval is above 0, the claim supported by it is as follows:

The southern frogs are likely to have a greater mean number of croaks per hour than the northern frogs.

Answer:

a=(x+7)(x+-2)

Step-by-step explanation:

(x+a)(x+b)=x²+(a+b)x+(ab)

Answer:

  a) (x +7)(x -2)

  b) x = -7 or +2

Step-by-step explanation:

A trinomial is factored by realizing that the constant term (-14) is the product of the binomial constants, and the coefficient of the linear term (5) is their sum. Here, we can examine the factorization of -14 to see which factors may have a sum of 5:

  -14 = (-1)(14) = (-2)(7) = (-7)(2) = (-14)(1)

Sums of these factor pairs are 13, 5, -5, -13. Clearly, we could stop writing factorizations when the sum stops being positive. The values of interest are -7 and 2. They tell us the trinomial is factored as ...

  x² +5x -14 = (x +7)(x -2)

__

The zeros of the quadratic are the values of x that make the above factors be zero. The zero product rule tells you the only way the product will be zero is for a factor to be zero.

  x +7 = 0   ⇒   x = -7

  x -2 = 0   ⇒   x = 2

The solutions are x = -7 or x = 2.

The maximum profit is $288, and you should charge $6 per dozen.

Let's assume that demand depends linearly on price, such that we can write:

q = a*p + b

where q is the demand and p is the price.

We have 3 points of that line:

The slope of the line is given by:

[tex]a = \frac{q_2 - q_1}{p_2 - p_1}[/tex]

Where these are values of demand and prize for two different points, if we use the first two points we get:

[tex]a = \frac{72 - 80}{3 - 2} = -8[/tex]

Then the line is something like:

q = -8*p + b

Remember that when p = 2, the demand is equal to 80, replacing that we get:

80 = -8*2 + b

80 + 16 = b = 96.

So the line is:

q = -8*p + b

Profit is given by the product between the demand and the price, so we have.

Profit = p*q = p*(-8*p + 96) = -8p^2 + 96p

We want to maximize that, notice that is a quadratic equation of negative leading coefficient, so the maximum is at the vertex, using the equation for the vertex of a quadratic equation we will see that the maximum is at:

p = -96/(2*-8) = 6

Then the maximum profit is:

profit = -8*(6)^2 + 96*6 = 288

The maximum profit is $288, and you should charge $6 per dozen.

Step-by-step explanation:

Abby's January finance charge is $7.22, the correct option is C.

Adjusted balance method: Based on finance charges on the amount(s) owed at the end of the current billing cycle after posted credits and payments.

The total amount on which interest will be applied using the adjusted balance method is;

[tex]=722.10 + 18.12-65.00 +18.00 + 44.79+ 34.25 - 40.00\\\\= 732.26[/tex]

Abby’s January finance charge will be;

[tex]= 732.26 \times 11.83 \times \dfrac{30}{360}\times \dfrac{1}{100}\\\\= 7.22[/tex]

Hence, Abby's January finance charge is $7.22.

Answer:

[tex]y^{10}-\dfrac{25}{64}x^2[/tex]

Step-by-step explanation:

Given expression:

[tex](\frac58x+y^5)(y^5-\frac58 x)[/tex]

Change the order of the terms in the first parentheses:

[tex]\implies (y^5+\frac58x)(y^5-\frac58 x)[/tex]

Apply the Difference of Two Squares: [tex](a+b)(a-b)=a^2-b^2[/tex]

[tex]\implies (y^5)^2-(\frac58x)^2[/tex]

Apply exponent rule [tex](a^b)^c=a^{b\cdot c}[/tex]

[tex]\implies y^{10}-(\frac58x)^2[/tex]

Apply exponent rule [tex]\left(\dfrac{a}{b}\right)^c=\dfrac{a^c}{b^c}[/tex]

[tex]\implies y^{10}-\left(\dfrac{5^2}{8^2}x^2\right)[/tex]

[tex]\implies y^{10}-\dfrac{25}{64}x^2[/tex]

Answer:

x = 5

Step-by-step explanation:

Given:

To Find:

What is the value of x?

Note:

Two angles that add up to give you 90° is a complementary angle.

Thus, Since angle A and angle B sum up to give 90°, they are complementary angles.

Solve:

The following equation can be created to solve for the value of x:

m ∠A + m∠ B

Substitute

40 + 4x + 30 = 90

Add like terms

4x +70 = 90

Subtract 70 from both sides

4x = 90-70

4x = 20

Divide both sides by 4

x = 5

Therefore, the value of x is 5
