1. A decreases

Mathematics
1 answer:
Anit [1.1K]3 years ago
3 0
<span>Answer:
1. B increases 
2. </span><span>D 4
</span><span>3. A. every 15 minutes

The exponent function can be described as an= a0(r)^n where
a0= the initial value
r= the ratio of growth of decay
n= the time

In this question, the initial value would be 120, the ratio would be 1.04 and the time would be 4t.
The ratio is 1,04 or can be said as 104%. The graph should be growing since the ratio is >1. So, the first answer is increases.
The ratio is 104% which means 4% more than the original value(100%). So the next answer would be 4%.
The time used in the graph is 4t and the unit used by t is hours. That means, the growing happens for every 1/4 hour. If you change it into minute, it would be: 1/4* 60 minutes/hour=  15 minutes</span>

Allushta [10]

Answer:

3\frac{17}{25}

Step-by-step explanation:

368%

<em>convert to a fraction</em>

\frac{368}{100}

<em>divide top and bottom by 2</em>

<em />\frac{184}{50}<em />

<em>divide top and bottom by 2</em>

<em />\frac{92}{25}<em />

92/25 = 3 remainder 17

The volumes of two similar solids are 1331 m3 and 216 m3. the surface area of the larger solid is 324 m3. what is the surface ar
zavuch27 [327]
Two solids are said to be similar when their corresponding sides and angles are proportional and congruent. Since the solids here are similar, we calculate as follows:

Assuming the solid is a sphere
V1/V2 = r1^3 / r2^3 = 1331/216 = 6.16203
r1/r2 = 11/6

A1/A2 = (r1/r2)^2
324/A2 = (11/6)^2
A2 = 42.84 m^2

You are working in a small, student-run company that sends out merchandise with university branding to alumni around the world.
topjm [15]

Answer:

The answer is "0.142466".

Step-by-step explanation:

Using the p formula for the proportion of nonconforming units through the subgrouping which can vary in sizes:

p =\frac{np}{n}\\\\

\bar{p}=\frac{\Sigma np}{\Sigma n}\\\\

Defects = \frac{5}{100} \times 50 \\\\

p = \frac{5}{100} \times \frac{50}{50}=0.05\\\\

It calculates the controls limits through the p-chart that is:

UCL_{p},LCL_{p}=\bar{p} \pm \sqrt{\frac{\bar{p}(1-\bar{p})}{\bar{n}}}\\\\

So, the upper control limits:

= 0.05 + 3 \times \sqrt{(\frac{0.05\times(1-0.05)}{50})} \\\\= 0.142466

0.7 (3s + 4)-1.1s = 7.9
vichka [17]

Answer:

s = 5.1

Step-by-step explanation:

0.7 (3s + 4)-1.1s = 7.9\\

Multiply both sides of the equation by 10

0.7\left(3s+4\right)\cdot \:10-1.1s\cdot \:10=7.9\cdot \:10\\\\= 7\left(3s+4\right)-11s=79\\

Expand

\mathrm{Expand\:}7\left(3s+4\right)-11s:\\\quad 10s+28

Subtract 28 from both sides

10s+28-28=79-28

Simplify

10s=51

Divide both sides of the equation by 10

\frac{10s}{10}=\frac{51}{10}

Simplify

s=\frac{51}{10}\\\\Decimal = 5.1
