Answer:

T= 160 + 4x

Step-by-step explanation:

Giving the following information:

The $160 fine is a fixed cost. It will remain constant.

The $4 additional fine acts as a variable cost. It varies with the number of miles per hour.

To calculate the total cost (T), we need to use the following formula:

T= 160 + 4x

x= miles per hour exceeding the speed limit.

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

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

Step-by-step explanation:

The question implies the two angles are equal because of the positioning of the named vertices. m∠A = m∠E so to say.

You can substitute the values and solve the inequality to find x, then solve for m∠A.

m∠A = m∠E; Given (Inferred)

6x - 8 = 4x + 1; Substitution

6x = 4x + 9; Addition Property of Equality

2x = 9; Subtraction Property of Equality

x = 4.5; Division Property of Equality

m∠A = 6x - 8; Given

m∠A = 6(4.5) - 8; Substitution

m∠A = 19; Solve

Answer:

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

Answer:

X=13

Step-by-step explanation:

So if ΔABC ≅ ΔDEC, then that means that ∠B is ≅ ∠E. Therefore you would write the equation 3x=6x-39 and solve for X to get 13.

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]

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
