Answer:

The length of s is 5.1 inches to the nearest tenth of an inch

Step-by-step explanation:

In Δ RST

∵ t is the opposite side to ∠T

∵ r is the opposite side to ∠R

∵ s is the opposite side to ∠S

→ To find s let us use the cosine rule

∴ s² = t² + r² - 2 × t × r × cos∠S

∵ t = 4.1 inches, r = 7.1 inches, and m∠S = 45°

→ Substitute them in the rule above

∴ s² = (4.1)² + (7.1)² - 2 × 4.1 × 7.1 × cos(45°)

∴ s² = 16.81 + 50.41 - 41.1677568

∴ s² = 26.0522432

→ Take √ for both sides

∴ s = 5.10413981

→ Round it to the nearest tenth

∴ s = 5.1 inches

∴ The length of s is 5.1 inches to the nearest tenth of an inch

Answer:

i think 7 but i am not 100% sure

Step-by-step explanation:

The smallest possible whole number length for the third side is 7

Case 1

1st + 2nd > 3rd

5 + 11 > 3rd

16 > 3rd

3rd length < 16

Case 2

1st + 3rd > 2nd

5 + 3rd > 11

3rd > 11 - 5

3rd > 6

Thus, we have

6 < 3rd length < 16

Since the 3rd length is greater than 6, then the smallest possible length for the 3rd side is 7

Answer:

The 90% confidence interval is  [tex]0.1316 <  p <  0.1812[/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n  =  582

   The number of teenagers at the wheel is k = 91

Generally the sample proportion is mathematically represented as

          [tex]\^ p = \frac{k}{n}[/tex]

=>       [tex]\^ p = \frac{91}{582}[/tex]

=>      [tex]\^ p = 0.1564[/tex]

From the question we are told the confidence level is  90% , hence the level of significance is    

      [tex]\alpha = (100 - 90 ) \%[/tex]

=>   [tex]\alpha = 0.10[/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645[/tex]

Generally the margin of error is mathematically represented as  

     [tex]E =  Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p (1- \^ p)}{n} } [/tex]

=>  [tex]E =  1.645 * \sqrt{\frac{0.1564  (1- 0.1564)}{582} } [/tex]

=>  [tex]E =  0.0248 [/tex]

Generally 95% confidence interval is mathematically represented as  

      [tex]\^ p -E <  p <  \^ p +E[/tex]

=>   [tex]0.1564  -0.0248 <  p <  0.1564  + 0.0248[/tex]

=>   [tex]0.1316 <  p <  0.1812[/tex]

Answer:

C. 57

Step-by-step explanation:

all triangles add up to 180. the tick marks show that ∠D and ∠ E are congruent so you do this and solve for x:

(4x + 1) + (4x + 1) + (5x - 4) = 180

13x - 2 = 180

13x = 182

x = 182/13

x = 14

4(14) + 1 = 57

Step-by-step explanation:

Division of Rational Expressions

When dividing two rational expressions like f(c) / g(c), it's usually easier to multiply the numerator by the reciprocal of the denominator: f(c) * (1/g(c)). The reciprocal is just flipping the numerator and the denominator.

Let's find the following division:

[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}[/tex]

First, we factor the polynomials where possible.

[tex]c^2-64 = (c-8)(c+8)[/tex]

[tex]3c^2+26c+16=(3c+2)(c+8)[/tex]

[tex]c^2-4c-32=(c-8)(c+4)[/tex]

[tex]15c+10=5(3c+2)[/tex]

Substituting:

[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}=\frac{\frac{(c-8)(c+8)}{(3c+2)(c+8)}} {\frac{(c-8)(c+4)}{5(3c+2)}}[/tex]

Multiplying by the reciprocal of the denominator:

[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}=\frac{(c-8)(c+8)}{(3c+2)(c+8)}\cdot \frac{5(3c+2)}{(c-8)(c+4)}[/tex]

Simplifying by (c+8)(3c+2)(c-8):

[tex]\displaystyle \frac{\frac{c^2-64}{3c^2+26c+16}} {\frac{c^2-4c-32}{15c+10}}=\frac{5}{(c+4)}[/tex]

Answer:
