y = 3x² + 1
Differentiate both sides with respect to t :
dy/dt = 6x dx/dt
We're given that dy/dt = +3 units/second, so when x = 2 we find
3 u/s = 6 • 2 dx/dt
dx/dt = 3/12 u/s = 1/4 u/s
which means x is increasing at a rate of 1/4 units per second.
When using inverse operations, what should you do to solve x + 7 = 10
Answer:
10-7=3
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
Since we are doing inverse, the opposite of adding is subtracting, so 10-7 is 3.
When using inverse operations, what should you do to solve y - 7 = 10?
Answer:
17
Step-by-step explanation:
There is a SUBTRACTION symbol in the problem. So, you will do the opposite, & ADD the 2 available numbers in the equation. 10+7=17
When you replace that y with 17, the equation is correct.
MARK BRAINLIEST!!!!!!! At a display booth at an amusement park, every visitor gets a gift bag. Some of the bags have items in them as shown in the table below. Items in the Gift Bags Items Bags Hat Every 2nd visitor T-shirt Every 7th visitor Backpack Every 10th visitor How often will a bag contain all three items? LCM or GCF?
Answer:
Step-by-step explanation:
you would find the least common multiple. If you have a set number of gift bags, and you want to find how many had all 3 at once, you would find the LCM that fit within the number of gift bags that you had in order to find it. in this case, it would be 1 in 70

An estate of $485,000 is left to three siblings. The eldest receives 3 times as much as the youngest. The middle sibling receives $13,000 more than the youngest. How much did each receive?
Answer:
Step-by-step explanation:
the youngest received 94,200
the middle received 107,200
the eldest received 283,600
Step-by-step explanation:
Given parameters:
Worth of the estate = $485000
Unknown:
Amount received by each sibling = ?
Solution:
Let the amount received the eldest = e
middle = m
youngest = y
e = 3y
m = y + 13000
so;
e + m + y = 485000
3y + y + 13000 + y = 485000
5y = 485000 - 13000
5y = 472000
y = $94400
Eldest = 3y = 3 x 94400 = $283200
Middle = $94400 + $13000 = $107400
Youngest = $94400

Step-by-step explanation:
We can first find the equation of the line in point-slope form. The slope of the line is given by [tex](y_2-y_1)/(x_2-x_1)[/tex], which is (-5-(-3))/(1-(-2)), or -2/3. The equation for a line in point-slope form is [tex]y-y_1=m(x-x_1)[/tex] where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is a point on the line -- in this case, we may use (1, -5). Therefore, the equation for the line is y + 5 = -2/3 (x-1).
The question asks for the equation of the line in standard form -- which is [tex]Ax+By=C[/tex]. We can get this by simplifying the equation above to get[tex]2x+3y=-13[/tex].

The volume of a cone is 1/3 that of a cylinder when the radius and height are the same (v= 1/3(pi)(r)^2(h). What is the volume of a cone with a radius of 10 inches and a height of 12 inches.
[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the Surface Areas and Volumes.
Since, Volume of cone = 1/3 π r^2 h,
here, r = 10 Inches and h= 12 inches, also π =3.14
so, VOC = 1/3 π (10)^2 × (20)
VOC = 1/3(3.14)(100)(20)= 2093.33 inch^3
=> so the volume of the cone is 2093.33 cubic inches.
The coordinates of both the pre-image and image of quadrilateral JKLM are listed in the table
below.
Which rule best represents this dilation?
A- (x, y) -> (4/11 x, 4/11 y)
B- (x,y) -> (3/22 x, 3/22 y)
C- (x, y) -> (11/4 x, 11/4 y)
D- (x, y) -> (22/3 x, 22/3 y )
Answer:
Option C.
Step-by-step explanation:
From the table attached,
Pre-image coordinates J(-8, 2) → Image coordinates J'(-22, 5.5)
J(-8, 2) → J'(-22, 5.5)
Since, rule for the dilation of a point is,
(x, y) → (kx, ky) [Here k = scale factor of dilation]
Therefore, kx = -22
k(-8) = -22
k = [tex]\frac{-22}{-8}[/tex]
k = 2.75
So the scale factor should be 2.75
From the given options,
Option A.
(x, y) → [tex]\frac{4}{11}(x, y)[/tex]
→ 0.36(x, y)
But value of k should be 0.36
Therefore, Incorrect option.
Option B.
(x, y) → [tex]\frac{3}{22}(x, y)[/tex]
→ 0.14(x, y)
k = 0.14
But the value of k should be 2.75
Incorrect option.
Option C.
(x, y) → [tex]\frac{11}{4}(x, y)[/tex]
→ 2.75(x, y)
k = 2.75
Therefore, this option is correct.
Option D.
(x, y) → [tex]\frac{22}{3}(x, y)[/tex]
→ 7.33(x, y)
k = 7.33
But the scale factor should be 7.33
Incorrect option.

Answer:
3/5 of a tank
Step-by-step explanation:
You can use a proportion.
3/4 tank is to 5 days as x is to 4 days
(3/4)/5 = x/4
Cross multiply.
5x = 3/4 * 4

Car Sales A manufacturer of economy cars has determined that 50,000 cars per month can be sold at a price of $18,000 per car. At a price of $17,500, the number of cars sold per month would increase to 55,000. Determine a linear function that predicts the number of cars that will be sold at a price of x dollars. Use this model to predict the number of cars that will be sold at a price of $17,000.
Answer: 60,000 cars would be sold at $17000.
Step-by-step explanation:
• first we find the slope of the function between two points
(50,000, 18000) and ( 55,000, 17500)
• Let the number of cars sold be the x axis coordinate.
and the price is the y axis coordinate.
• next we plot this points.
m= Change in y / Change in x = rise / run
The slope m = (18000 - 17500/ 50,000 - 55,000)
= -0.1
• The equation of the line in point slope form is m(x-x1)=(y-y1)
• substituting for the first point
-0.1 (X-50,000) = y-18000
-0.1x - 5000 = y - 18000
-0.1x = 18000 + 5000
y = -0.1x + 23000
our slope -0.1 is negative.
In order to find the number of cars to be sold at a price of $17000, substitute this value y in the equation such that:
17000 =-0.1x+23000
solve for x
-0.1x = 23000-17000
0.1x = 6000
divide both sides by 0.1
x = 60000
60,000 cars would be sold at $17,000

If ABCD is a parallelogram. BC=13 and AB=5, what is the perimeter of the parallelogram?
Answer:
36
Step-by-step explanation:
In a Parallelogram , it is important to note that opposite sides are equal to each other.
We are given parallelogram ABCD.
We have sides: AB, BC, CD, AD.
Since opposite sides are equal then:
AB = CD
BC = AD
The perimeter of a parallelogram is the sum of all its sides.
In the question: BC=13 and AB=5
Hence,
AB = CD = 5
BC = AD = 13
Perimeter of Parallelogram ABCD = 5 + 5 + 13 + 13
= 36.
