3. Use your graphing calculator to find the value of f'(0) for f(x) = cos(x) - eX. (4 points)
Answer:
-1
Step-by-step explanation:
Derivative of cos(x)=-sin(x)
Derivative of e^x=e^x
Derivative of cos(x)-e^x= - sin(x)-e^x
plug in 0 to the spots of x and you will get 1 because sin(0) is 0 e^0 is 1

The cost of fencing a square garden at the rate of Rs.5 per
metre is Rs. 2000. Find the total length of the fence.
[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]
Cost per metre = Rs. 5
Total cost = Rs. 2000
Then total length of the fence = Rs.2000/Rs.5
= 400 metre
Total length of the fence = 400 metre
A spherical hot air balloon has a diameter of 55 feet when the balloon is inflated the radius increases at a rate of 1.5 feet per minute. approximately how long will it take to inflate a balloon 2/3 of its maximum volume? use. 3.14 as pie
Answer: 46.90mins
Step-by-step explanation:
The given data:
The diameter of the balloon = 55 feet
The rate of increase of the radius of the balloon when inflated = 1.5 feet/min.
Solution:
dr/dt = 1.5 feet per minute = 1.5 ft/min
V = 4/3·π·r³
The maximum volume of the balloon
= 4/3 × 3.14 × 55³
= 696556.67 ft³
When the volume 2/3 the maximum volume
= 2/3 × 696556.67 ft³
= 464371.11 ft³
The radius, r₂ at the point is
= 4/3·π·r₂³
= 464371.11 ft³
r₂³ = 464371.11 ft³ × 3/4
= 348278.33 ft³
348278.333333
r₂ = ∛(348278.33 ft³) ≈ 70.36 ft
The time for the radius to increase to the above length = Length/(Rate of increase of length of the radius)
The time for the radius to increase to the
above length
Time taken for the radius to increase the length.
= is 70.369 ft/(1.5 ft/min)
= 46.90 minutes
46.90mins is the time taken to inflate the balloon.
If correct will mark brainliest!!!!

y is inversely proportional to x. Given that y = 12 and x = 6. Find the value of y when x = 8.
Answer:
9
Step-by-step explanation:
formula for inverse proportion is y = [tex]\frac{k}{x}[/tex]
k is the constant of probability
to find k,
y is 12, x is 6
12 = [tex]\frac{k}{6}[/tex]
so x = 12 × 6
∴ k is 72
so y = [tex]\frac{72}{8}[/tex]
∴ y is 9
Need Answer ASAP I ONLY HAVE 5 min.
Answer:
B
Step-by-step explanation:
The answer is B since after cross multiplying 150 against all of the fractions you get 25.
Answer:
25
Step-by-step explanation
1/5 of 150 is 30
1/3 of 150 is 50
1/10 of 150 is 45
add all that together and get 125
150-125=25
Ann, Brian and Carol share the cost of a car. Ann pays 25 of the cost, Brian pays 13 and Carol pays the rest.

b) Ann pays $1600 more than Brian. Find the total cost of the car.
Complete question :
Ann, Brian and Carol share the cost of a car. Ann pays 2/5 of the cost, Brian pays 1/3 and Carol pays the rest.
a) What fraction of the cost does Carol pay?
b) Ann pays $1600 more than Brian. Find the total cost of the car.
Answer:
4/ 15
8000
Step-by-step explanation:
A)
Fraction carol paid :
Total fraction = 1/1
Fraction paid by Ann and Brian = (2/5 +1/3)
(2/5 + 1/3) = (6 + 5) / 15 = 11/15
1 - 11/ 15 = 4/ 15
Ann = 2/5 ; Brian pays 1/3
Ann pay 1600 more than Brian
2/5 - 1/3 = (6 - 5) = 1/5
1/5 of amount = 1600
If :
1/5 = 1600
1 = x
1/5x = 1600
x = 1600 ÷1/5
Total amount = 8000

Step-by-step explanation:
Second rectangle and third rectangle are resulting rectangles scale drawings of one another
What is Area of Rectangle?The area of Rectangle is length times of width.
Given,
Gayla draws a rectangle.
Second rectangle:
Jared then draws a different rectangle by increasing both the length and the width by 5%.
Third rectangle:
Lyda draws a third rectangle by increasing both the length and the width of Gayla’s by 5 inches.
Let us assume 1 inches as 1 percentage.
So second rectangle and third rectangle are resulting rectangles scale drawings of one another

find the curved surface area of a cylindrical tank of base radius 30 cm and height 2m
Answer:
37 700m² (rounded off to 3 s.f.)
Step-by-step explanation:
When the curved surface area of a cylindrical tank is laid out, it will be like a rectangular piece of sheet with the circumference of the base circle as its length and the height as its breadth.
Circumference of base circle with radius 30cm = pi × 30 × 2
= 60pi
2m = 200cm
Curved surface are = 60pi × 200
= 12 000pi
= 37 700m² (rounded off to 3 s.f.)
