Step-by-step explanation:

got it right on edge

Answer:

A = 51 pages

N = 71 pages

Nolan will be 20 pages farther along in the book than Addison after 4 days.

Step-by-step explanation:

for Addison if you multiply 11 by 4 you get 44 then you add 7 you get 51

For Nolan if you multiply 6 by 4 you get 24 then you add 47  and you final answer is 71

The value of sin(2x) is [tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]

The cosine ratio is given as:

[tex]\cos(x) = -\frac 14[/tex]

Calculate sine(x) using the following identity equation

[tex]\sin^2(x) + \cos^2(x) = 1[/tex]

So we have:

[tex]\sin^2(x) + (1/4)^2 = 1[/tex]

[tex]\sin^2(x) + 1/16= 1[/tex]

Subtract 1/16 from both sides

[tex]\sin^2(x) = 15/16[/tex]

Take the square root of both sides

[tex]\sin(x) = \pm \sqrt{15/16[/tex]

Given that

tan(x) < 0

It means that:

sin(x) < 0

So, we have:

[tex]\sin(x) = -\sqrt{15/16[/tex]

Simplify

[tex]\sin(x) = \sqrt{15}/4[/tex]

sin(2x) is then calculated as:

[tex]\sin(2x) = 2\sin(x)\cos(x)[/tex]

So, we have:

[tex]\sin(2x) = -2 * \frac{\sqrt{15}}{4} * \frac 14[/tex]

This gives

[tex]\sin(2x) = - \frac{\sqrt{15}}{8}[/tex]

Step-by-step explanation:

Answer:

Explanation:

To simplify a polynomial, we have to do two things: 1) combine like terms, and 2) rearrange the terms so that they're written in descending order of exponent.

First, we combine like terms, which requires us to identify the terms that can be added or subtracted from each other. Like terms always have the same variable (with the same exponent) attached to them. For example, you can add 1 "x-squared" to 2 "x-squareds" and get 3 "x-squareds", but 1 "x-squared" plus an "x" can't be combined because they're not like terms.

Let's identify some like terms below.

f(x)=−4x+3x2−7+9x−12x2−5x4

Here you can see that -4x and 9x are like terms. When we combine (add) -4x and 9x, we get 5x. So let's write 5x instead:

f(x)=5x+3x2−7−12x2−5x4

Let's do the same thing with the x-squared terms:

f(x)=5x+3x2−7−12x2−5x4

f(x)=5x−9x2−7−5x4

Now there are no like terms left. Our last step is to organize the terms so that x is written in descending power:

f(x)=−5x4−9x2+5x−7

Step-by-step explanation:

[tex]-6x+5y=16x+4y=-10\\Let\\-6x+5y=-10(1)\\16x+4y=-10(2)\\8(1)+3(2):\\48x+48x+40y+12y=-80-30\\52y=-110\\y= -\frac{110}{52} =-\frac{55}{26}[/tex]

Answer:

[tex]\frac{5}{-1.6}<-3\frac{3}{10}-(-\frac{7}{20})<5\frac{6}{15}+(-2\frac{4}{5})<-4.5\times -2.3[/tex]

Step-by-step explanation:

We will solve the given expressions and find the answer in decimals.

1). [tex]5\frac{6}{15}+(-2\frac{4}{5})[/tex] = [tex]5\frac{2}{5}-2\frac{4}{5}[/tex]

                   = 5.4 - 2.8

                   = 2.6

2). [tex]-3\frac{3}{10}-(-\frac{7}{20})=-3\frac{3}{10}+\frac{7}{20}[/tex]

                           = -3.3 + 0.35

                           = -2.95

3). [tex]\frac{5}{-1.6}=-\frac{5}{1.6}[/tex]

      = -3.125

4). (-4.5) × (-2.3) = 10.35

Solution of the expressions in the increasing order will be,

-3.125 < -2.95 < 2.6 < 10.35

[tex]\frac{5}{-1.6}<-3\frac{3}{10}-(-\frac{7}{20})<5\frac{6}{15}+(-2\frac{4}{5})<-4.5\times -2.3[/tex]

Answer:

\sqrt{81 + x^2} = y

\sqrt{y^2 - 7^2} = x

Step-by-step explanation:

They would be Pythagorean Triples.

a^2 + b^2 = c^2

9^2 + x^2 = y^2

\sqrt{81 + x^2} = y

7^2 + x^2 = y^2

x^2 = y^2 - 7^2

\sqrt{y^2 - 7^2} = x

Answer:

∠1 ≅ ∠2 ⇒ proved down

Step-by-step explanation:

#11

In the given figure

∵ BA // CF

∵ BC is a transversal

∵ ∠1 and ∠BCF are interior alternate angles

∵ The interior alternate angles are equal in measures

∴ m∠1 = m∠BCF

∴ ∠1 ≅ ∠BCF ⇒ (1)

∵ BC // ED

∵ CF is a transversal

∵ ∠BCF and ∠2 are corresponding angles

∵ The corresponding angles are equal in measures

∴ m∠BCF = m∠2

∴ ∠BCF ≅ ∠2 ⇒ (2)

→ From (1) and (2)

∵ ∠1 and ∠2 are congruent to ∠BCF

∴ ∠1 and ∠2 are congruent

∴ ∠1 ≅ ∠2 ⇒ proved

Answer:

The system of inequalities that represents this situation will be:

[tex]f + s < 10[/tex]

[tex]f - s > 3[/tex]

Step-by-step explanation:

Given that the sum of the two numbers is less than 10. As 'less than' can be represented by '<'.

Given that If we subtract the second number from the first, the difference is greater than 3. As 'greater than' can be represented by '>'.

Thus, the system of inequalities that represents this situation will be:

[tex]f + s < 10[/tex]

[tex]f - s > 3[/tex]

v = $100x + $120

Step-by-step explanation:

In this scenario, the fixed amount would be the $120 that Leslie's sister gave her. While $100 would be multiplied by the number of months (x) that have passed by which in this scenario would be our variable since we do not have this information. Lastly, these two values would be added to give us Leslie's total savings (v)

v = $100x + $120
