Answer:

b, e

Step-by-step explanation:

a, b) ordinarily, we claim the variable on the vertical axis is a function of the variable on the horizontal axis. By that claim, <em>temperature is a function of time</em>.

If the graph passed the horizontal line test (a horizontal line intersects in one place), then we could also say time is a function of temperature. The graph does not pass that test, so we cannot make that claim.

c) The graph has negative slope between 4:00 and 5:00. Temperature is decreasing in that interval, not increasing.

d) The graph has two intervals in which it is horizontal: 5:00-9:00 and 11:00-12:00. In those intervals it is neither increasing nor decreasing.

e) The graph shows a minimum in the interval 11:00-12:00. <em>The lowest temperature first occurs at 11:00</em>.

Lulu has exactly enough fencing to go around her rectangular garden. She has 40 m of fencing and the garden is 8 m wide. What is

vesna_86 [32]

Answer:12 m

Step-by-step explanation:

Given

Width of garden $W=8\ m$

Total fencing $T=40\ m$

If Lulu has enough fencing to go around her rectangular garden then , it should be equal to perimeter of garden

Suppose L is the length of garden

Therefore perimeter is $P=2(L+W)$

$2(L+W)=40$

$L+W=20$

$L=20-8=12\ m$

thus length of fencing is $12\ m$

GEOMETRY

ira [324]

Answer:

Its like how much you multiply the original shape by, to the new one.

For example, if your new shape is double the size of the original shape, then the scale factor is 2, because you would multiply the original by 2, to get the size of the new.

However, if your new shape is half the size, then the scale factor is 1/2, as you multiply the original by half to get the new shape.

Hope this cleared things up, lmk down below if you any further questions.

Ash company report sales of $430,000 for year 1, $480,000 for year 2 and $530000 for year 3. Using year 1 as the base year, what

TiliK225 [7]

Answer:

12% increase

Step-by-step explanation:

Each year the sales increase by $50,000.

430,000 + 50,000 = 480,000

480,000 + 50,000 = 530,000

To find the percent change, write a proportion using 2 of the years.

$\frac{480,000}{430,000}=\frac{x}{100}$

To solve for x, cross multiply the numerator with the denominator of each fraction.

480,000(100) = 430,000(x)

48,000,000 = 430,000x

111.62 = x

Rounded this is 112% or 12% above 100%.
