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

0-1=-1

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

Answer:

The x intercept is at (1,0)

The HCM and LCM of 120 and 180 are 360.

The Highest Common Factor (HCF) of two or more given numbers is the largest number that divides each of the given numbers without leaving any remainder. The Least Common Multiple (LCM) of two or more numbers is the smallest of the common multiples of those numbers.

Given are two numbers as -

120 and 180

We can write 120 and 180 as -

120 = 2 x 2 x 2 x 3 x 5

180 = 2 x 2 x 3 x 3 x 5

HCF of 120 and 180 will be equal to = 2 x 2 x 3 x 5 = 60

Now, we can find LCM using the formula -

LCM(a, b) = (a x b)/HCF(a, b)

LCM(a, b) = (120 x 180)/60

LCM(a, b) = 2 x 180 = 360

Therefore, the HCM and LCM of 120 and 180 are 360.

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

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.

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

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.)

Given that, A cylindrical tank of base radius is 30cm and it's height is 2m or, 200cm

We need to find the curved surface area

We know that,

➩ Curves surface area of a cylinder = 2πrh

r (radius) = 30cm.

h (height) = 200cm.

Therefore,

➩ Curves surface area of a cylinder:

Second rectangle and third rectangle are resulting rectangles scale drawings of one another

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

Hence,  second rectangle and third rectangle are resulting rectangles scale drawings of one another
