The average of Landry’s test scores must be at least 92 for her to make an A in Algebra class.
She got a 95 on her first test. What grade can Landry get on her second test to make an A in the class
Answer:
89
Step-by-step explanation:
On the first test, she got 3 more points than the average required, so she can afford to drop 3 points below the average on her second test. She needs 92-3 = 89 or better.

Solve forx:
3x + 2 = 11
Answer:
x = 3
Step-by-step explanation:
3x + 2 = 11
Subtract 2 from both sides:
3x + 2 - 2 = 11 - 2
3x = 9
Divide both sides by 3:
3x / 3 = 9 / 3
x = 3

The admission fee to a state fair is $8.00. Each ride costs an additional $4.00. Karen only has $30.00.Which inequality could be used to determine the number of rides, x, Karen can go on?
Answer: 8 + 4x ≤ 30
Step-by-step explanation:
Since it costs $8 for Karen to enter the state fair and $4 each ride she goes, you would add 8 and 4x and include the less than or equal to sign symbol because Karen only has $30 and she got not spend anymore than $30.

pls help me to find K as the subject of formula
Answer:
k = [tex]\frac{u^2y-x}{u^2-1}[/tex]
Step-by-step explanation:
Given
u = [tex]\sqrt{\frac{k-x}{k-y} }[/tex] ( square both sides )
u² = [tex]\frac{k-x}{k-y}[/tex] ← multiply both sides by (k - y)
u²(k - y) = k - x ← distribute left side
u²k - u²y = k - x ( subtract k from both sides )
u²k - k - u²y = - x ( add u²y to both sides )
u²k - k = u²y - x ← factor out k from each term on the left side
k(u² - 1) = u²y - x ← divide both sides by (u² - 1)
k = [tex]\frac{u^2y-x}{u^2-1}[/tex]

Step-by-step explanation:
Can someone thoroughly explain this implicit differentiation with a trig function. No matter how many times I try to solve this, I get it wrong. I’ve tried the quotient rule, and I’ve tried multiplying that (8 + x^2) to the other side to do the chain + product rule. I wanna know where I went wrong
Answer:
[tex]\frac{dy}{dx}=y'=\frac{\sec^2(x-y)(8+x^2)^2+2xy}{(8+x^2)(1+\sec^2(x-y)(8+x^2))}[/tex]
Step-by-step explanation:
So we have the equation:
[tex]\tan(x-y)=\frac{y}{8+x^2}[/tex]
And we want to find dy/dx.
So, let's take the derivative of both sides:
[tex]\frac{d}{dx}[\tan(x-y)]=\frac{d}{dx}[\frac{y}{8+x^2}][/tex]
Let's do each side individually.
Left Side:
We have:
[tex]\frac{d}{dx}[\tan(x-y)][/tex]
We can use the chain rule, where:
[tex](u(v(x))'=u'(v(x))\cdot v'(x)[/tex]
Let u(x) be tan(x). Then v(x) is (x-y). Remember that d/dx(tan(x)) is sec²(x). So:
[tex]=\sec^2(x-y)\cdot (\frac{d}{dx}[x-y])[/tex]
Differentiate x like normally. Implicitly differentiate for y. This yields:
[tex]=\sec^2(x-y)(1-y')[/tex]
Distribute:
[tex]=\sec^2(x-y)-y'\sec^2(x-y)[/tex]
And that is our left side.
Right Side:
We have:
[tex]\frac{d}{dx}[\frac{y}{8+x^2}][/tex]
We can use the quotient rule, where:
[tex]\frac{d}{dx}[f/g]=\frac{f'g-fg'}{g^2}[/tex]
f is y. g is (8+x²). So:
[tex]=\frac{\frac{d}{dx}[y](8+x^2)-(y)\frac{d}{dx}(8+x^2)}{(8+x^2)^2}[/tex]
Differentiate:
[tex]=\frac{y'(8+x^2)-2xy}{(8+x^2)^2}[/tex]
And that is our right side.
So, our entire equation is:
[tex]\sec^2(x-y)-y'\sec^2(x-y)=\frac{y'(8+x^2)-2xy}{(8+x^2)^2}[/tex]
To find dy/dx, we have to solve for y'. Let's multiply both sides by the denominator on the right. So:
[tex]((8+x^2)^2)\sec^2(x-y)-y'\sec^2(x-y)=\frac{y'(8+x^2)-2xy}{(8+x^2)^2}((8+x^2)^2)[/tex]
The right side cancels. Let's distribute the left:
[tex]\sec^2(x-y)(8+x^2)^2-y'\sec^2(x-y)(8+x^2)^2=y'(8+x^2)-2xy[/tex]
Now, let's move all the y'-terms to one side. Add our second term from our left equation to the right. So:
[tex]\sec^2(x-y)(8+x^2)^2=y'(8+x^2)-2xy+y'\sec^2(x-y)(8+x^2)^2[/tex]
Move -2xy to the left. So:
[tex]\sec^2(x-y)(8+x^2)^2+2xy=y'(8+x^2)+y'\sec^2(x-y)(8+x^2)^2[/tex]
Factor out a y' from the right:
[tex]\sec^2(x-y)(8+x^2)^2+2xy=y'((8+x^2)+\sec^2(x-y)(8+x^2)^2)[/tex]
Divide. Therefore, dy/dx is:
[tex]\frac{dy}{dx}=y'=\frac{\sec^2(x-y)(8+x^2)^2+2xy}{(8+x^2)+\sec^2(x-y)(8+x^2)^2}[/tex]
We can factor out a (8+x²) from the denominator. So:
[tex]\frac{dy}{dx}=y'=\frac{\sec^2(x-y)(8+x^2)^2+2xy}{(8+x^2)(1+\sec^2(x-y)(8+x^2))}[/tex]
And we're done!

What is the approximate average rate of
change for the height of the plant, measured in
centimeters per day, between day 20 and day
40?(leave answer in fraction and decimal)
Answer:
Average change in height of the plant is 0.5 cm per day.
Step-by-step explanation:
Height of the plant on day 20 = 40 cm
Height of the plant on day 40 = 50 cm
Change in height = 50 - 40 = 10 cm
Number of days between day 20 and day 40 = 20
Average change in height of the plant = [tex]\frac{\text{Change in height of the plant}}{\text{Duration}}[/tex]
= [tex]\frac{10}{20}[/tex]
= 0.5 cm per day
Therefore, average change in height of the plant is 0.5 cm per day.
At the beginning of a snowstorm, Evan had 3 inches of snow on his lawn. The snow then began to fall at a constant rate of 3 inches per hour. Assuming no snow was melting, how much snow would Evan have on his lawn 3 hours after the snow began to fall? How much snow would Evan have on his lawn after tt hours of snow falling?
Answer:
3+3tt=total amount of snow
Step-by-step explanation:
y=mx+b is used to show increase
In this case, b is the original 3 inches of snow. m is the constant growth, and x is tt, or the amount of time it is being compared to. y is the total.
The snowfall is at a constant rate of 3 inches per hour, then after 3 hours the snow in the lawn will be 12 inches and after t hours snow in the lawn will be 3 + 3(t).
What is an equation?Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the given scenario in the question,
Snow in the lawn = 3 inches
Rate of snow fall = 3 in/hr
So, the snow fall in 3 hours = 3 + 3(3) = 12 inches
And, snow fall after t hours = 3 + 3(t), here t is the number of hours.
