Answer:

5tan25°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan25° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{CA}{5}[/tex] ( multiply both sides by 5 )

5tan25° = CA

4) Given that the polynomial p(x) = 2x4 - 3x2 + 6x + k.
Find the value of k if (x - 1) is a factor of p(x).
{ANS: k = -5)​

Answers

Answer:

k = - 5

Step-by-step explanation:

Given that (x - 1) is a factor of p(x) then p(1) = 0, that is

2 - 3 + 6 + k = 0

5 + k = 0 ( subtract 5 from both sides )

k = - 5

(6n-25) + (3n + 20) = 180

Answers

Answer:

n = 185/9

Step-by-step explanation:

(6n-25) + (3n + 20) = 180

Combine like terms

9n -5 = 180

Add 5 to each side

9n - 5 +5 = 180+5

9n = 185

Divide each side by 9

9n/9 = 185/9

n = 185/9

6 years ago, Kelly was younger than Kendall by 6 years. The total age of Kelly and Kendall now is 52 years. What was Kendall's age 6 years ago?

Answers

Answer:

Kendall's age 6 years ago was 23 years.

Step-by-step explanation:

A system of equations is a set of equations with the same unknowns. A  system of linear equations is a system of equations in which each equation is linear. That is, a system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.

In this case you propose a system, being the variables to solve:

x: Kelly's age 6 years agoy: Kendall's age 6 years ago

6 years ago, Kelly was younger than Kendall by 6 years. The total age of Kelly and Kendall now is 52 years. So, the system of equations is:

[tex]\left \{ {{x=y-6} \atop {(x+6)+(y+6)=52}} \right.[/tex]

It is solved by the substitution method, which consists of solving one of the unknowns in one of the equations and substituting its value in the following one. The first equation is replaced in the second equation of the system:

(y-6+6)+(y+6)=52

y +(y+6)= 52

y +y+6= 52

2*y + 6=52

2*y= 46

y= 46 ÷ 2

y=23

So, Kendall's age 6 years ago was 23 years.

Step-by-step explanation:

The diagram shows a triangle ABC in which AB= 6 cm, BC=8 cm and ABC = 90°.
Calculate the length of AC.

The answer should be 12. please help with explanation and calculation!!!

Answers

Answer:

AC = 10

Step-by-step explanation:

This is a right triangle

use the pythagorean theorem

a² + b² = c²

6² + 8² = c²

36 + 64 = c²

100 = c²

Take the square root of both sides

10 = c

AC = 10

The correct answer is 10 not 12

Choose all the equations that are true if y = 6. 52.37 – 46.37 = y 45y =445 8y = 48 3.2 + y = 9 y ÷ 4 = 24

Answers

Answer:

52.37 – 46.37 = y

8y = 48

Step-by-step explanation:

Choose all the equations that are true if y = 6. 52.37 – 46.37 = y 45y =445 8y = 48 3.2 + y = 9 y ÷ 4 = 24

We solve for y in all the equations :

52.37 – 46.37 = y

52.37 – 46.37 = 6 (True)

45y =445

Divide both sides by 45

45y/45 = 445/45

y = 9.888 (False)

8y = 48

y = 48/8

y = 6 (True)

3.2 + y = 9

y = 9 - 3.2

y = 5.8 (false)

y ÷ 4 = 24

y/4 = 24

y = 24 * 4 = 96 ( false)

A box of chocolate is divided among Jim, Jack and David. David gets 2/5 of the box and Jack gets 1/5 of David's share and the rest which was given to Jim was 260 grams. What is David's share in Grams?

Answers

Answer:

200

Step-by-step explanation:

Jack share = 2/5 x 1/5 = 2/25

amount left over = 1 - (2/25 + 2/5) = 13/25

13/25 x t = 260

t = total amount of chocolate

t = (260 x 25) / 13 = 500

Davids share = 2/5 x 500 = 200

In order to simulate conditions near roads treated with road salt, scientists raised wood frog tadpoles in a high concentration of salt, and tadpole survival was measured. The survival rates for 5 replicates were 32, 37, 41, 45, and 50 percent. The sample mean for these values is 41 percent, and the sample variance is 48.5 percent squared. Determine the standard error of the sample mean for this data set.

Answers

Answer:

[tex]SE_{\bar x} = 0.311[/tex]

Step-by-step explanation:

Given

[tex]n=5[/tex]

[tex]\bar x = 41\%[/tex]

[tex]\sigma^2= 48.5\%[/tex] --- variance

Required

The standard error of the sample mean

This is calculated as:

[tex]SE_{\bar x} = \frac{\sigma}{\sqrt n}[/tex]

This can be rewritten as:

[tex]SE_{\bar x} = \frac{\sqrt{\sigma^2}}{\sqrt n}[/tex]

So, we have:

[tex]SE_{\bar x} = \frac{\sqrt{48.5\%}}{\sqrt 5}[/tex]

Rewrite as:

[tex]SE_{\bar x} = \sqrt{\frac{48.5\%}{5}}[/tex]

[tex]SE_{\bar x} = \sqrt{0.097}[/tex]

[tex]SE_{\bar x} = 0.311[/tex]

Andres went out to a restaurant for dinner. His total bill before tax and tip was $27.30. He was charged an additional 9% tax and he also paid a 15% tip on the original bill.

Answers

Answer:

$25.66

Step-by-step explanation:

Given data

Total Bill before tax and tip= $27.30

Tax= 9%

Tip= 15%

Let us find the tax

=9/100*27.30

=0.09*27.30

=$2.457

Let us find the tip

=15/100*27.30

=0.15*27.30

=$4.095

Therefore his bill after tax and tip is

=27.30+2.457-4.095

=$25.66
