Answer 1

From the given quadratic function ff(x) = (x² + cx - 1)/(2x² - 3x + 2), we can tell that the possible values for which the function  lies on the interval (-1, 2) is; c c ≤ 12

What is the solution to the quadratic function?

We are given the quadratic function f(x) as;

f(x) = (x² + cx - 1)/(2x² - 3x + 2)

Now, we want to find the possible values of c for which the function belongs to the interval (-1, 2). Thus, we will plug in -1 for x and equate the function to 2;

f(-1) = ((-1)² + c(-1) - 1)/(2(-1)² - 3(-1) + 2) = 2

(1 - c - 1)/6 = 2

-c/6 = 2

c = -12

Thus, the possible values  for which the given function f(x) belongs to the interval (-1, 2) are; c ≤ 12

Find the median, mode, and range.

Answers

For the given discrete data series,

Median = 4'7"

Mode = 4'8"

Range = 1'3"

To begin with, let us arrange the given discrete data series in ascending order as follows:

3'7"     3'11"    4'3"    4'6"      4'7"      4'7"     4'8"      4'8"      4'8"     4'9"   4'10"

To identify the median, locate the data point that stands exact at midpoint of the series. It is the sixth entry from left and hence median = 4'7"

To identify the mode, count and identify which data points occurs highest in frequency. 4'8" is mode as it occurs highest number of times (3 times) in the series.

To calculate the range, we subtract the last entry. Thus Range = 4'10" - 3'7" = 1'3"

What is linear / non-linear equation ?

An equation is a statement in which the values of two mathematical expressions are equal. These statements consist of constants and variables. Constants are values that never change. Variables like y or x represent unknown numerical values. Nonlinear equations are equations that appear as curved lines when you graph them. After plotting pairs of values that make the equation true on a coordinate grid, you can't draw a straight line between the points.

Calculation

from the question given we can come to an equation that is

2( x+7) - 4 = 28

if the number chosen by Janet is x

lets find x

2x + 14 - 4 = 28

2x = 18

x = 9

write an equation for there consevite integers whose sum id 306

Answers

The equation for three consecutive integers whose sum is 36 is n + (n+1) + (n+2) = 306.

What is an equation?

A mathematical statement called an equation includes the sign "equal to" between two expressions with equal values.

What are consecutive numbers?

Whole numbers that follow one another without a gap are known as consecutive integers.

Given the sum of three consecutive integers = 306

Let the integers be n, n+1, n+2

Then, n + (n+1) + (n+2) = 306

⇒3n + 3 = 306

⇒n = 303/3

⇒n = 101

Hence, n+1 = 102 and n+2 = 103

Therefore, the equation for three consecutive integers whose sum is 36 is n + (n+1) + (n+2) = 306.

An object is enlarged in a scale drawing. An expansion increases or decreases the size of an object by multiplying each of its lengths by a scale factor. Consequently, when using scale drawings: Find out what the drawing's scale is. Use a ruler to measure the distance on the drawing (or, if available, count the number of squares). To get the distance in real life, multiply the measurement by the scale.

(100 points) While practicing a tightrope walk at a height of 20 feet, a circus performer slips and falls into a safety net 15 feet below. The function h(t) = -16t^2+20, where t represents time measured in seconds, gives the performer's height above the ground (in feet) as he falls. Write and solve an equation to find the elapsed time until the performer lands in the net. Will give brainiest to person who answers the questions correctly.

Answers

The equation to find the elapsed time is  -16t^2 + 20 + 15 = 0 and the elapsed time is 1.479 seconds

How to determine the equation to find the elapsed time?

The given parameters are:

h(t) = -16t^2 + 20

Also, we have:

Safety net = 15 feet below

This means that

h(t) = -15

Substitute h(t) = -15 in h(t) = -16t^2 + 20

So, we have

-16t^2 + 20 = -15

Add 15 to all sides

-16t^2 + 20 + 15 = 0

Using a graphing calculator, we have

t = -1.479 and t = 1.479

Time cannot be negative

So, we have

t = 1.479

Hence, the time is 1.479 seconds

Neil bought a house for £235 000
In the first year the value of the house depreciated by 4%
In each of years 2 and 3 the value of the house increased by 6%
Work out the value of the house at the end of year 3

Answers

Answer:

Based on the given conditions, formulate: 235000×(1+1-4%)

Calculate the sum or difference:235000×(2-0.04)

Calculate the sum or difference:235000×1.96

Calculate the product or quotient:460600

get the result:460600

So the answer is 460600

Answer:

£ 253,484.16

Step-by-step explanation:

Cost of house for first year = £235,000

Year 1

Depreciation for first year  is 4% = 4/100

Depreciation in £ = 235,000 x 4/100 = £9,400

Effective value of house at end of first year
= 235000 - 9400 = £225,600

Year 2

In the second year the house  value increased by 6% = 6/100

So total increase in £ at the end of year 2 with an initial value of £225,600 = £225,600 x 6/100 = £13,536

So actual value of house at end of year 2
= £225,600 + £13,536
= £239,136

Year 3

The value increased by 6% for year 3.

Value at beginning of year 3 = £239,136

Increase in value at 6% = £239,136 x 6/100 = £14,348.16

Total Value at end of year 3

=  £239,136 + £14,348.16

= £253,484.16

Answer: £253,484.16

Note
Another way of quickly calculating this is noting that 4% depreciation means the new value is  (1 - 4%) of initial value = 1 - 4/100 = 0.96

An increase of 6% means the new value will be 1.06 times the initial value

So the value of the house after 4% depreciation for the first year and 6% appreciation for the next  2 years

= 235000 x (0.96)(1.06)(1.06) = 253,484.16

therefore it forms a right angled triangle.

given hypotenuse is 30inch

the height is 18 inches

using the Pythagorean theorem

[tex] {hypotense}^{2} = {width}^{2} + {height}^{2} [/tex]

then

[tex] {30}^{2} = {width}^{2} + {18}^{2} \\ 900 = {width}^{2} +324[/tex]

Subtract 324 from both sides

Then,

Volume = 2s ×2s×2s
