(18x-44) + (8x-10) = 180

26x-54 = 180

26x = 234

x = 9

8(9)-10 + (13y-38) = 180

72-10+13y-38 = 180

13y+24 = 180

13y=156

y=12

What is the volume of a sphere with a diameter of 8 m use 3.14 for pie round your answer to the nearest hundredth
deff fn [24]

Volume of the sphere is 300 m³

Step-by-step explanation:

  • Step 1: Calculate volume of the sphere using the formula V = 4/3πr³, where r = d/2 = 4m

⇒ V = 4/3 × 3.14 × 4³ = 267.95 = 300 m³ (rounding off to the nearest hundredth)

The height of a model rocket is 4.5% of the height of the actual rocket.The model is 1.22 m high.How high is the actual rocket
Serjik [45]

Answer:

Actual Height = 27.11 m

Step-by-step explanation:

Given:

Height of model rocket = 4.5 % of actual Height

Model Height = 1.22 m

To Find:

Actual Height of rocket = ?

Solution:

We have to Find the Actual Height of the rocket

Let actual height be x

Now it is given that

Height of model rocket = 4.5 % of actual Height

As we have the values so putting it in it becomes

1.22 = 4.5 % * x

it could be written as

1.22=\frac{4.5}{100}*x

Multiplying both sides by \frac{100}{4.5}

it becomes

1.22*\frac{100}{4.5} = x

\frac{122}{4.5} = x

27.11 m =x

or

Actual Height = 27.11 m

Ln(x + 1) − ln(2) = 1
KonstantinChe [14]

Answer:

The answer to your question is: x = 4.44

Step-by-step explanation:

Data

                                          ln(x + 1) − ln(2) = 1

                                          In (x + 1)/2 = 1

                                          (x + 1) / 2 = e¹      

                                          x + 1 = 2 (2.7183)

                                          x = 5.44 - 1

                                          x = 4.44

Determine the location and values of the absolute maximum and absolute minimum of given function: f(x)= ( -x+2)^4, Where 0<=x
jeyben [28]

Answer:

The absolute maximum and the absolute minimum are (0, 16) and (2, 0).

Step-by-step explanation:

First, we obtain the first and second derivatives of the function by chain rule and derivative for a power function, that is:

First derivative

f'(x) = -4\cdot (-x+2)^{3}

Second derivative

f''(x) = 12\cdot (-x + 2)^{2}

Then, we proceed to do the First and Second Derivative Tests:

First Derivative Test

-4\cdot (-x+2)^{3} = 0

-x + 2 = 0

x = 2

Second Derivative Test

f''(2) = 12\cdot (-2+2)^{2}

f''(2) = 0

The Second Derivative Test is unable to determine the nature of the critical values.

Then, we plot the function with the help of a graphing tool. The absolute maximum and the absolute minimum are (0, 16) and (2, 0).
