Answer: $248.68

Step-by-step explanation:

Given

Money compounded according to

[tex]\Rightarrow V=Pe^{rt}\\[/tex]

Here, P=$127

r=4.2%

t=16 years

[tex]\Rightarrow V=127e^{0.042\times 16}\\\\\Rightarrow V=127e^{0.672}=127\times 1.958\\\\\Rightarrow V=\$248.68[/tex]

Value after 16 years is $248.68

Answer: 248.69

Step-by-step explanation:

r= 4.2%

=0.042

r=4.2%=0.042

and then just b

Answer:

the answers for 72-y=6 is 66

Answer:

its 66 bc if ur subtracting y from 72 to get 6 it has to be that

Answer:

They are both non liner

Step-by-step explanation:

This is because any expression with the added such as +5 in x+5 would result in the graph to not meets in its orgin. So both of them are no.

Answer:

12

Step-by-step explanation:

4, 8, 6, 10, 8, ... has the pattern of +4 then -2

so, 4+4=8

8-2=6

6+4=10

10-2=8

the pattern goes on

so, 8+4=12

so, you  can get the pattern 8, 6, 10, 8, 12, ...

and the answer is 12

Answer:

c

Step-by-step explanation:

have a good day :D

to find the slope you take two points and add the y values and divide it by the x values

so you take the points (0,-2) and (3,2)

the y values are -2and2

2+2=4

the x values are 0 and 3

0+3=0

4/3=4/3 so that table does represent an equation with a slope of 4/3

sorry if this doesnt make sense its hard to explain virtually

How long she waits in Wellington

From the question:

She takes the 10 30 from Christchurch

So:

[tex]Christchurch\ Depart = 10\ 30[/tex]

This implies that:

She has to wait until Wellington arrives at 11 15

So:

[tex]Wellington\ Arrives= 11\ 15[/tex]

So, the wait time is:

[tex]Wait\ time = Wellington\ Arrives - Christchurch\ depart[/tex]

[tex]Wait\ time = 11: 15 - 10: 30[/tex]

[tex]Wait\ time = 1:45\ hr[/tex]

42.74 m²

Step-by-step explanation:

full circle area = πr² = (3.14)(7²) = 153.86 m²

(100°/360°)(153.86 m²) = 42.74 m²

Answer:

your friend by 50 seconds

Step-by-step explanation:

150 divided by 3 equals to 50 so you would also divide 120 minutes by 3 to get 40

You: 50 meters per 45 seconds

Friend: 50 meters in 40 seconds

50 times 10 equals 500 meters so we will multiply both number of seconds by 10

You:45*10=450

Friend: 40*10=400

450>400 so the friend swims the fastest

450-400= is 50 seconds

So the friend swims the fastest by 50 seconds

Answer:

B) The top right choice.

Step-by-step explanation:

The graph of the equation y = - 2x + 5 is shown in figure.

Option 2 is true.

The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The equation is,

⇒ y = - 2x + 5

Now,

Since, The equation is,

⇒ y = - 2x + 5

By comparing of the slope - intercept form of the equation of line,

y = mx + b we get;

⇒ Slope = - 2

And, The y - intercept = 5

So, The graph of the equation is passes through the point (0, 5) with slope - 2.
