Answer:

1. it is not a direct variation because the value k is not kept throughout the ordered pairs

2. -a^5 - 2a³ + 2a², leading coefficient is -1

Step-by-step explanation:

1. to find the direct variation, we will use y/x = k with k representing our constant throughout the chart. if every value is equal to k, it is a direct variation

for this problem we will assume that the cup sizes are x and the cost is y

so the ordered pairs are (8, 0.90), (12, 1.35), (16, 1.80), and (24, 2.25)

.90/8 = 0.1125 <-- this is our k value for which every result has to be equal to

1.35/12 = 0.1125

1.80/12 = 0.1125

2.25/24 = 0.09375

since the value k was not kept throughout the ordered pairs, this is not a direct variation

2. the standard form of a polynomial is the exponents in descending order.

we have the following polynomial: 2a² - a^5 -2a³

to write it in standard form, we will go in descending order of the exponents. the largest exponent being first

-a^5 - 2a³ + 2a²

the leading coefficient of the polynomial is -1, as there is a negative sign in front of the newly formed polynomial

The width of a rectangle is 4 inches greater than half the length. The perimeter is 56 inches. What is the length and the width

yulyashka [42]

Answer:

Length of the rectangle = 16 inches

Width of the rectangle = 12 inches

Step-by-step explanation:

Let the length of the rectangle be represented by x.

Then width can be expressed as $\[\frac{x}{2}+4\]
$

Perimeter of a rectangle is the sum of four sides of the rectangle.

This can be expressed as 2*(length + breadth)

= $2* (x + \frac{x}{2}+4)$

= $2* (\frac{3x}{2}+4)$

= $3x + 8$

But perimeter is given as 56.

So, $\[3x + 8 = 56\]
$

=> $3x = 48$

=> $x = 16$

Hence length of the rectangle = 16 inches

Width of the rectangle = $\frac{16}{2}+4$ = 12 inches

A multinational firm wants to estimate the average number of hours in a month that theiremployees spend on social media while on

elena55 [62]

Answer:

95% of the population spent between 16.8 hours to 26.2 hours on social media per month

Step-by-step explanation:

subtracting 1 from sample size: 83-1= 82
Note Mean=21.5 and standard deviation=2.5
Subtracting confidence interval from 1 and dividing by 2: (1-0.95)/2=0.025
At α=0.025 and dF=82, the t-distribution table gives 1.984
Divide standard deviation by square root of sample size: 21.5/√83= 2.36
Multiplying answer in step 4 by answer in step 5: 2.36×1.984= 4.68
For lower end: 21.5-4.68= 16.82
for upper end: 21.5+4.68=26.18

Please help!!!

stiv31 [10]

Answer:

Step-by-step explanation:

1. Percent means out of 100

8% = 8/100

.08

2. Is means equals and of means multiply

W = 48% *180

W = .48 *180

W =86.4

3. Is means equals and of means multiply

80 = 125% * W

80 = 1.25 W

Divide each side by 1.25

80/1.25 = W
