show that the equation x^3 + x - 3 has a solution between 1 and 2

Answers

Answer 1

Answer:

see explanation

Step-by-step explanation:

Evaluate the polynomial at x = 1 and x = 2

x = 1 : 1³ + 1 - 3 = 1 + 1 - 3 = - 1

x = 2 : 2³ + 2 - 3 = 8 + 2 - 3 = 7

Then ( 1, - 1 ) → (2, 7 )

Shows the polynomial goes from y = - 1 to y = + 7

The change in sign indicates the graph crosses the x- axis between 1 and 2

Thus indicating a solution between x = 1 and x = 2

Because the angles are opposite each other they are equal so we can say

4x-25=75

4x=100

x=25

x= 25

4x -25 = 75 ( vertically opposit angle)

4x = 100

x = 100/4

x= 25

angle = 75

Item 4 Identify the initial amount $a$ and the rate of growth $r$ (as a percent) of the exponential function $y=12\left(1.05\right)^t$ . Evaluate the function when $t=5$ . Round your answer to the nearest tenth.

Answers

Answer:

Initial amount = 12

Rate of growth = 5%

value of the function when t t = 5 is 15.3

Step-by-step explanation:

The standard exponential growth equation is expressed as;

y = A(1+r)^t

A is the initial amount

r is the rate of growth

t is the time

Given the expression y = 12(1.05)^t

On comparing with the general formula;

A  = 12

Hence the initial amount is 12

Also;

1 + r  = 1.05

r = 1.05 -1

r = 0.05

r = 0.05 * 100

r = 5%

The rate of growth is 5%

To evaluate the function when t = 5, we will substitute t = 5 into the given function as shown;

Recall that y = A(1+r)^t

y = 12(1.05)^5

y = 12(1.2763)

y = 15.3 (to the nearest tenth)

Answer:

4/15

Step-by-step explanation:

Since Hannah spent 1/3 of the money on books and 2/5 of the money on presents, she currently has 1/3 * 900 = 300 dollars gone on books and 2/5 * 900 = 360 dollars gone on presents. Adding them, she has a total of 660 dollars gone on both books and presents. Now, we need to find the fraction of the 900 dollars that she has left. We need to divide the remaining money (900 - 660 = 240) by the total money she had to figure that out.

240 / 900 = 4/15

A farmhouse shelters 16 animals, some are pigs, and some are ducks. Altogether there are 42 legs. How many pigs are there?

Answers

Answer:

5 pigs

Step-by-step explanation:

A farmhouse shelters 16 animals, some are pigs, and some are ducks. Altogether there are 42 legs. How many pigs are there?

Let us represent:

Number of pigs = x

Number of ducks = y

Our system of equations is given as:

A farmhouse shelters 16 animals, some are pigs, and some are ducks.

x + y = 16...... Equation 1

x = 16 - y

Altogether there are 42 legs.

Ducks have 2 legs(feet) , pigs have 4 legs,

4x + 2y = 42..... Equation 2

We substitute

16 - y for x in Equation 2

Hence:

4(16 - y) + 2y = 42

64 - 4y + 2y = 42

Collect like terms

- 4y + 2y = 42 - 64

-2y =- 22

y = -22/-2

y = 11 ducks

Solving for x.

x = 16 - y

x = 16 - 11

x = 5 pigs

Therefore, we have 5 pigs

wait quotient? You have an addition symbol between them, I guess ill calculate both

For the symbol that you put in you equation (3 - 5i) + (2 - 5i), this equals 5 - 10i

For dividing both of the expressions, (3 - 5i) / (2 - 5i) = 31/29 + 5i/29

So if you were actually adding them use the first answer, if you were dividing them and used the wrong symbol in the question, use the second answer.

  x = 19.25

Step-by-step explanation:

Each half of the rhombus is an isosceles triangle. The two "base" angles are the same measure, and the sum of all angles is 180°:

  (2x -1)° +(2x -1)° +(4x+28)° = 180°

  8x = 154 . . . . . . . . . . divide by °, collect terms, subtract 26

  x = 154/8

  x = 19.25

__

Check

The angle measures are ...

  (2x -1)° = (2(19.25) -1)° = 37.5°

  (4x +28)° = (4(19.25) +28)° = 105°

Then the angle sum is 37.5 +37.5 +105 = 180, as it should be.
