Answer:

Word Problem. Hmm

The Interpretation of the first expression

Let boat top speed be x and car's top speed be y

x= 3y/5 – 2

From the question

x= 73miles per hr

73= 3y/5 - 2

3y/5 = 73+2

3y/5=75

y= 75x5/(3)

y=125miles per hr.

This is the car's top speed. Thanks

Answer:

34.3

Step-by-step explanation:

Answer:  The answer is  (34.3)

Step-by-step explanation:

Since you're rounding to the nearest tenth,  you gotta look at the hundreds place which is 8. 8 rounds up so therefore, 2 rounds up and becomes 3. Which gives you the answer (34.3)

Associative property

Step-by-step explanation:

When three or more numbers are multiplied, the answer is the same regardless of the way in which the numbers are grouped.

Answer:

P = -3t

Step-by-step explanation:

Since it starts at time zero, and our velocity is -3m/s, our equation for position could be modeled for time as P = -3t

Answer:

4r^2

Step-by-step explanation:

The area of a square is the square of the side length. Since a circle with radius r is inscribed inside the square, the side length of the square is 2r. Therefore, the area of the square is (2r)^2, which is 4r^2.

Note that the area of the circle is [tex]\pi r^2[/tex].

Answer:

Linear Pair Theorem

Step-by-step explanation:

Linear Pair Theorem:

If two angles form a linear pair, then they are supplementary, and the sum of their measures is 180°.

The answer is B not any other mostly because you need to

subtract both equations to remove the variable.

Answer:

x ≥ 15

Step-by-step explanation:

200 + 20x ≥ 500

To solve this inequality, you must first subtract 200 from 500.

500 - 200 = 300.

Lastly, divide 300 by 20.

20x = 300

300 ÷ 20 = 15

Therefore, the value of x is 15.

Answer:

x ≥ 15

Step-by-step explanation:

1. So first of all we can simplify both sides now turning this into 20x+200≥500

2. Next we go ahead and subtract 200 from both sides because that is the opposite of adding, so something like this:

20x + 200 ≥ 500

        -200   -200

This equals to:

20x ≥ 300

Now so x can be cancled we will need to divide by 20 because that is the opposite of multiplying(When it shows the x next to a number like this 20x it means that they are multiplyin):

20x  ≥  300

20        20

Now we cance out the left side(x) equaling up to this:

x ≥ 15

I hope this helped you out!

Answer:

3

Step-by-step explanation:

10+4x

10+12 = 22

so what number times 4 equals 12. So the answer is 3

Answer:

"The square root of 12 is represented in the radical form as √12, which is equal to 2√3. Since 2√3 cannot be further simplified, hence such roots are called surds"

Answer:

[tex]f(g(-4)) = 18[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4x + 6[/tex]

[tex]g(x) = x^2 + x - 9[/tex]

Required

Find f(g(-4))

First, calculate f(g(x))

We have:

[tex]f(x) = 4x + 6[/tex]

[tex]f(g(x)) = 4g(x) + 6[/tex]

Substitute: [tex]g(x) = x^2 + x - 9[/tex]

[tex]f(g(x)) = 4[x^2 + x - 9] + 6[/tex]

Open bracket

[tex]f(g(x)) = 4x^2 + 4x - 36 + 6[/tex]

[tex]f(g(x)) = 4x^2 + 4x-30[/tex]

Substitute [tex]-4[/tex] for [tex]x[/tex]

[tex]f(g(-4)) = 4*(-4)^2 + 4*(-4)-30[/tex]

[tex]f(g(-4)) = 64 -16 -30[/tex]

[tex]f(g(-4)) = 18[/tex]

Answer:

[tex] \displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3} [/tex]

Step-by-step explanation:

we would like to figure out the derivative of the following:

[tex] \displaystyle \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} } [/tex]

to do so, let,

[tex] \displaystyle y = \frac{ { 3x }^{2} - 2x - 1 }{ {x}^{2} } [/tex]

By simplifying we acquire:

[tex] \displaystyle y = 3 - \frac{2}{x} - \frac{1}{ {x}^{2} } [/tex]

use law of exponent which yields:

[tex] \displaystyle y = 3 - 2 {x}^{ - 1} - { {x}^{ - 2} } [/tex]

take derivative in both sides:

[tex] \displaystyle \frac{dy}{dx} = \frac{d}{dx} (3 - 2 {x}^{ - 1} - { {x}^{ - 2} } )[/tex]

use sum derivation rule which yields:

[tex] \rm\displaystyle \frac{dy}{dx} = \frac{d}{dx} 3 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2} [/tex]

By constant derivation we acquire:

[tex] \rm\displaystyle \frac{dy}{dx} = 0 - \frac{d}{dx} 2 {x}^{ - 1} - \frac{d}{dx} {x}^{ - 2} [/tex]

use exponent rule of derivation which yields:

[tex] \rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ - 1 -1} ) - ( - 2 {x}^{ - 2 - 1} )[/tex]

simplify exponent:

[tex] \rm\displaystyle \frac{dy}{dx} = 0 - ( - 2 {x}^{ -2} ) - ( - 2 {x}^{ - 3} )[/tex]

two negatives make positive so,

[tex] \displaystyle \frac{dy}{dx} = 2 {x}^{ -2} + 2 {x}^{ - 3} [/tex]

by law of exponent we acquire:

[tex] \displaystyle \frac{dy}{dx} = \frac{2 }{x^2}+ \frac{2}{x^3} [/tex]

simplify addition:

[tex] \displaystyle \frac{dy}{dx} = \frac{2x + 2}{x^3} [/tex]

and we are done!
