Using first principle, find the slope of a tangent line to the curve f(x) = x^2 - 3x +5 at x=3
Answer:
y=3x−4
Step-by-step explanation:
find the tangent line to f(x)=x2−3x+5 at x=3
First, find the value of the function at the given point: y0=f(3)=5
Second, find the slope of the tangent line, which is the derivative of the function, evaluated at the point: m=f′(3)
Find the derivative: f′(x)=2x−3
Next, we evaluate the derivative at the given point to find the slope.
m=f′(3)=3
Finally, the equation of the tangent line is y−y0=m(x−x0)
Plug the values that we found, we get that y−(5)=3(x−(3))
So basically: y=3x−4

A.y = 4 x + 12
B.y = negative 4 x
C.y = negative 12
D.y = negative 4 (x + 3)
Answer:
Option B
Step-by-step explanation:
When all options are graphed along withe the equation in the question,
[tex]y=-4x[/tex] does not intercept with [tex]y=-4x-12[/tex].
This means that y=-4x and y=-4x-12 will have no solution.
Option B should be the correct answer.
4 Happy Tam cat food can be purchased in four different packages.
Pack 1: 24 x 250 g cans for $39.99
Pack 2: 12 X 300 g cans for $24.99
Pack 3: 9 X 400 g cans for $25.99
Pack 4:6 X 1 kg can for $38.50
Which of the following shows the packs ordered from best to worst buy? Select the correct
answer A, B, C or D.
A 4213
B 3214
C 4123
D 2134
Answer:
C. 4123.
Step-by-step explanation:
We calculate the cost of a gram of cat food for each package.
Pack 1: Cost of 1 gram = total cost / number of grams
= 39.99 / (24 * 250)
= $0.00665 '
Pack 2: The cost is 24.99 / (12 * 300)
= $0.00694.
In a similar way
Pack 3: The cost is $ 0.0722
Pack 4: The cost is $0.00642 .
So the answer is
4123
PLEASE HELP IM TRYING TO PASS MY FINIALS!
Answer:
There is no real solution
Step-by-step explanation:
If you are finding the square root of a number, it cannot be negative. No number can be multiplied by itself to get a negative number. Negative numbers multiplied with themselves make a positive number. Positive numbers are obviously going to stay positive. Therefore there is no square root of -9
Plez halp with question bc im smol brain
Answer:
B. y= 2x–15
Step-by-step explanation:
The equation that represents the line that passes through the points (8, 1) and (10,5) is y= 2x–15
"x" is found on the left hand side of the bracket and "y" is found on the right hand side of the bracket :)
(8, 1) and (10, 5)
x in the first bracket is 8 and x in the second bracket is 10.
y in the first bracket is 1 and y in the second bracket is 5.
When this equation is applied to find the value for y we get:
y= 2x-15
y= 2(8)-15
y= 16-15
y= 1
y= 2x-15
y= 2(10)-15
y= 20-15
y= 5
We got back the values of y and this means that the equation was correctly chosen and the answer is correct :)
A cylinder has a base diameter of 8 centimeters and a height of 7 centimeters.what is its volume in cubic centimeters,to the nearest tenths place
The volume of the cylinder is approximately 351.9 cubic centimeters.
What is a cylinder?A cylinder is a 3-D figure that has a radius and a height.
The volume of a cylinder is given as πr²h.
Example:
The volume of a cup with a height of 5 cm and a radius of 2 cm is
Volume.
= 3.14 x 2 x 2 x 5
= 62.8 cm³
We have,
The volume of a cylinder can be calculated using the formula:
V = πr²h,
where r is the radius of the base and h is the height.
Since the base diameter is given as 8 centimeters, the radius is half of that or 4 centimeters.
Substituting these values into the formula, we get:
V = π (4 cm)² (7 cm)
V ≈ 351.86 cm³
Rounding this answer to the nearest tenth gives a final answer of V ≈ 351.9 cm^3.
Therefore,
The volume of the cylinder is approximately 351.9 cubic centimeters.

Tony will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $38 and costs an additional $0.13 per mile driven
The second plan has an initial fee of $49 and costs an additional $0.09 per mile driven
for what amount of driving do the two plans cost the
What to the cout when the two plans cout the same?
Answer:
He need to cover 275 miles for same cost for both plans
Step-by-step explanation:
Let x be the no. of miles
Case 1 :
Initial fee = $38
Additional cost of 1 mile = 0.13
Additional cost of x miles = 0.13x
So, total cost = 38+0.13x
Case 2 :
Initial fee = $49
Additional cost of 1 mile = 0.09
Additional cost of x miles = 0.09x
So, total cost = 49+0.09x
Now we are supposed to find amount of driving do the two plans cost the same
So, 38+0.13x=49+0.09x
0.13x-0.09x=49-38
0.04x=11
[tex]x=\frac{11}{0.04}[/tex]
x=275
Hence he need to cover 275 miles for same cost for both plans

write an equation in standard form for the line that passes through (3,-1) and (-5,-3)
Answer:
y = 1/4x - 1.75
Step-by-step explanation:
standard form is y = mx + b
to get m you need to calculate the slope between the given points
m= (y1-y2)/(x1-x2)
m = (-1 - (-3))/(3 - (-5)) = 2/8 = 1/4
now you need to find the constant b by plugging in one of your points
y = 1/4x + b
-1 = 1/4(3) + b
b = -1 - (3/4)
b = -7/4 or -1.75
Answer:
0 = x - 4y - 7
Step-by-step explanation:
Moving from (-5, -3) to (3, -1), we see that x (the run) increases by 8 and y (the rise) incrases by 2. Thus, the slope of the line connecting these two points is m = rise / run = 2/8, or 1/4.
Use the slope-intercept form of the equation of a straight line first:
y = mx + b becomes -1 = (1/4)(3) + b, or (after multiplying all three terms
by 4) -4 = 3 + 4b. Then 4b = -7, and b = -7/4.
Then the desired equation is y = (1/4)x - 7/4, or
4y = x - 7, or
0 = x - 4y - 7. This is the desired equation in standard form.

Julie and Ryan want to refinish the gym floor at the community center. The rectangular floor is 15.2 meters wide and 25.6 meters long. If each gallon of polyurethane covers about 180 square meters, how many gallons should they buy?
Answer:
3 gallons
Step-by-step explanation:
We need to find the area of the floor first:
25.6*15.2=389.12
Now we divide the surface area by gallons of polyurethane.
389.12÷180=2.161777777777777777777777777777....≈2.16 gallons needed. But OH WAIT! You can't buy 0.16 of a gallon so you need 3 gallons.
