Hi! i need help (It is due in a few hours)

Mathematics

Crazy boy [7]3 years ago

Answer:

1a and 2a

Step-by-step explanation:

<em>In the first one, </em>you should write an expression to help you picture what is happening. Since a test score is 4 times a quiz score which is x, a test score will be 4x. And since there are also 2 quizzes we should do 2x or just x + x. We then add the test score points and the quiz score points.

Here is the first way:

4x + 2x = 6x

Here is the second way:

4x + x + x = 6x

6x is your answer!

<em>In the second one, </em>you should also write an expression. Since a novel costs 6 more than a textbook which is represented by x, we will represent it the cost of a novel like this: x + 6. And since there is also one textbook we will just mark that as x. Now all we need to do is add them up/

This is what it will look like:

x + 6 + x = 2x + 6

2x + 6 is your answer!

I hope this helped! Please give Brainliest.

What is the answer for X^3=8/27
maksim [4K]

Answer:

x = 2 /3

Step-by-step explanation:

x^3 = 8/27

Take the cube root of each side

(x^3)^1/3 = (8/27)^1/3

We know that (a/b) ^c = a^c / b^c

x = (8 ) ^1/3 / (27)^1/3

x = 2 /3

Aleksandr [31]
Option A. y = 1.15 + 0.95x

1.15 is a fixed cost and 0.95 is a variable cost that has to be multiplied by the number of ounces of shrimp, x.

Use the substitution of x=e^{t} to transform the given Cauchy-Euler differential equation to a differential equation with consta
kherson [118]

By the chain rule,

\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\mathrm dy}{\mathrm dt}\dfrac{\mathrm dt}{\mathrm dx}\implies\dfrac{\mathrm dy}{\mathrm dt}=x\dfrac{\mathrm dy}{\mathrm dx}

which follows from x=e^t\implies t=\ln x\implies\dfrac{\mathrm dt}{\mathrm dx}=\dfrac1x.

\dfrac{\mathrm dy}{\mathrm dt} is then a function of x; denote this function by f(x). Then by the product rule,

\dfrac{\mathrm d^2y}{\mathrm dx^2}=\dfrac{\mathrm d}{\mathrm dx}\left[\dfrac1x\dfrac{\mathrm dy}{\mathrm dt}\right]=-\dfrac1{x^2}\dfrac{\mathrm dy}{\mathrm dt}+\dfrac1x\dfrac{\mathrm df}{\mathrm dx}

and by the chain rule,

\dfrac{\mathrm df}{\mathrm dx}=\dfrac{\mathrm df}{\mathrm dt}\dfrac{\mathrm dt}{\mathrm dx}=\dfrac1x\dfrac{\mathrm d^2y}{\mathrm dt^2}

so that

\dfrac{\mathrm d^2y}{\mathrm dt^2}-\dfrac{\mathrm dy}{\mathrm dt}=x^2\dfrac{\mathrm d^2y}{\mathrm dx^2}

Then the ODE in terms of t is

\dfrac{\mathrm d^2y}{\mathrm dt^2}+8\dfrac{\mathrm dy}{\mathrm dt}-20y=0

The characteristic equation

r^2+8r-20=(r+10)(r-2)=0

has two roots at r=-10 and r=2, so the characteristic solution is

y_c(t)=C_1e^{-10t}+C_2e^{2t}

Solving in terms of x gives

y_c(x)=C_1e^{-10\ln x}+C_2e^{2\ln x}\implies\boxed{y_c(x)=C_1x^{-10}+C_2x^2}

Marjorie bought 24 bottles of juice. Each day she opens and drinks 2 of these bottles of juice. Which inequality represents the
Anika [276]

Answer:

2d≤24

Step-by-step explanation:

Total number of bottled juice bought = 24 bottles

Amount she drank each day = 2 bottles

To get the inequality to represent greatest number of days she can continue before she has to replenish her stock, we will say;

1 day = 2 bottles

d days = 24 bottles

Cross multiply

2 * d = 1 * 24

2d = 24

Since we want to know the greatest number of days she can continue before she has to replenish her stock, the <u>equal to </u>to sign will be replaced with<u> less than or equal to</u> sign as shown;

2d≤24

<em>This shows that the maximum number of days she can continue before replenishing is 12days. It cannot exceed</em>
