It depreciates at 15%, which means it would be valued at 85% of the previous value.

After one year the value would be 9000 x 0.85 = £ 7650

Using a table of values, determine the solution to the equation below to the nearest fourth of a unit. 2^x=1-3^x
Greeley [361]

Answer:

Option (1)

Step-by-step explanation:

Given equation is,

2^x=1-3^x

To determine the solution of the equation we will substitute the values of 'x' given in the options,

Option (1)

For x = -0.75

2^{-0.75}=1-3^{-0.75}

0.59 = 1 - 0.44

0.59 = 0.56

Since, values on both the sides are approximately same.

Therefore, x = -0.75 will be the answer.

Option (2)

For x = -1.25

2^{-1.25}=1-3^{-1.25}

0.42 = 1 - 0.25

0.42 = 0.75

Which is not true.

Therefore, x = -1.25 is not the answer.

Option (3)

For x = 0.75

2^{0.75}=1-3^{0.75}

1.68 = 1 - 2.28

1.68 = -1.28

Which is not true.

Therefore, x = 0.75 is not the answer.

Option (4)

For x = 1.25

2^{1.25}=1-3^{1.25}

2.38 = 1 - 3.95

2.38 = -2.95

It's not true.

Therefore, x = 1.25 is not the answer.

The first one is correct because the angle on the opposite side is the same, and the second one is correct too because it's the same points.  So you can pick either or.

Winnona took five chapter tests. The table shows her scores. Test 1 2 3 4 5 Score 95 85 96 97 74 If Winnona retakes Test 5, what
mestny [16]

Answer:

The answer is A.

Step-by-step explanation:

Given that Winnona took 5 tests and retake Test 5. So the mean score for this question is Total number of scores divide by Total number of tests is equals to 87 :

Let Test 5's score be x,

Let mean score be 87,

\frac{95 + 85 + 96 + 97 + x}{5}  = 87

Next you have to solve the value of x :

373 + x = 87 \times 5 \\ 373 + x = 435 \\ 373 + x - 373 = 435 - 373 \\ x = 62 \:  \:  \: scores
